    This project was developed to conduct research to improve the efficacy of captive broodstock programs and advance hatchery reform throughout the Columbia River Basin. The project has three objectives: (1) maintain adaptive life history characteristics in Chinook salmon, (2) improve imprinting in juvenile sockeye salmon, and (3) match wild phenotypes in Chinook and sockeye salmon reared in hatcheries. A summary of the results are as follows: Objective 1: The ratio of jack to adult male Chinook salmon were varied in experimental breeding populations to test the hypothesis that reproductive success of the two male phenotypes would vary with their relative frequency in the population. Adult Chinook salmon males nearly always obtained primary access to nesting females and were first to enter the nest at the time of spawning. Jack male spawning occurred primarily by establishing satellite positions downstream of the courting pair, and 'sneaking' into the nest at the time of spawning. Male dominance hierarchies were fairly stable and strongly correlated with the order of nest entry at the time of spawning. Observed participation in spawning events and adult-to-fry reproductive success of jack and adult males was consistent with a negative frequency-dependent selection model. Overall, jack males sired an average of 21% of the offspring produced across a range of jack male frequencies. Implications of these and additional findings on Chinook salmon hatchery broodstock management will be presented in the FY 2009 Annual Report. Objective 2: To determine the critical period(s) for imprinting for sockeye salmon, juvenile salmon were exposed to known odorants at key developmental stages. Molecular assessments of imprinting-induced changes in odorant receptor gene expression indicated that regulation of odorant expression is influenced by developmental status and odor exposure history.

    This project was developed to conduct research to improve the efficacy of captive broodstock programs and advance hatchery reform throughout the Columbia river basin. The project has three objectives: (1) maintain adaptive life history characteristics in Chinook salmon, (2) improve imprinting in juvenile sockeye salmon, and (3) match wild phenotypes in Chinook and sockeye salmon reared in hatcheries. A summary of the results are as follows: Objective 1: Adult and jack Chinook salmon males were stocked into four replicate spawning channels at a constant density (N = 16 per breeding group), but different ratios, and were left to spawn naturally with a fixed number of females (N = 6 per breeding group). Adult males obtained primary access to females and were first to enter the nest at the time of spawning. Jack male spawning occurred primarily by establishing satellite positions downstream of the courting pair, and 'sneaking' into the nest at the time of spawning. Male dominance hierarchies were fairly stable and strongly correlated with the order of nest entry at the time of spawning. Spawning participation by jack and adult males is consistent with a negative frequency dependent selection model, which means that selection during spawning favors the rarer life history form. Results of DNA parentage assignments will be analyzed to estimate adult-to-fry fitness of each male. Objective 2: To determine the critical period(s) for imprinting for sockeye salmon, juvenile salmon were exposed to known odorants at key developmental stages. Molecular assessments of imprinting-induced changes in odorant receptor gene expression indicated that regulation of odorant expression is influenced by developmental status and odor exposure history. The results suggest that sockeye salmon are capable of imprinting to homing cues during the developmental periods that correspond to several of current release strategies employed as part of the Captive Broodstock program

    The US Congress funded the Puget Sound and Coastal Washington Hatchery Reform Project via annual appropriations to the US Fish and Wildlife Service (USFWS) beginning in fiscal year 2000. Congress established the project because it recognized that while hatcheries have a necessary role to play in meeting harvest and conservation goals for Pacific Northwest salmonids, the hatchery system was in need of comprehensive reform. Most hatcheries were producing fish for harvest primarily to mitigate for past habitat loss (rather than for conservation of at-risk populations) and were not taking into account the effects of their programs on naturally spawning populations. With numerous species listed as threatened or endangered under the Endangered Species Act (ESA), conservation of salmon in the Puget Sound area was a high priority. Genetic resources in the region were at risk and many hatchery programs as currently operated were contributing to those risks. Central to the project was the creation of a nine-member independent scientific review panel called the Hatchery Scientific Review Group (HSRG). The HSRG was charged by Congress with reviewing all state, tribal and federal hatchery programs in Puget Sound and Coastal Washington as part of a comprehensive hatchery reform effort to: conserve indigenous salmonid genetic resources; assist with the recovery of naturally spawning salmonid populations; provide sustainable fisheries; and improve the quality and cost-effectiveness of hatchery programs. The HSRG worked closely with the state, tribal and federal managers of the hatchery system, with facilitation provided by the non-profit organization Long Live the Kings and the law firm Gordon, Thomas, Honeywell, to successfully complete reviews of over 200 hatchery programs at more than 100 hatcheries across western Washington. That phase of the project culminated in 2004 with the publication of reports containing the HSRG's principles for hatchery reform and recommendations

    2012-02-01

    Full Text Available Steam methane reforming (SMR is one of the most promising processes for the production of hydrogen. Therefore, the overall thermodynamic efficiency of this process is of particular importance. The thermodynamic inefficiencies in a thermal system are related to exergy destruction and exergy loss. However, a conventional exergetic analysis cannot evaluate the mutual interdependencies among the system components nor the real potential for improving the energy conversion system being considered. One of the tools under development for the improvement of energy conversion systems from the thermodynamic viewpoint is the advanced exergetic analysis. In this paper, the avoidable part of the exergy destruction is estimated and the interactions among components of the overall system are evaluated in terms of endogenous and exogenous exergy destruction. The assumptions required for these calculations are discussed in detail, especially for those components that are typically used in chemical processes. Results of this paper suggest options for increasing the thermodynamic efficiency of hydrogen production by steam-methane reforming.

    1988-04-01

    This report provides information on the preliminary design of Umatilla Fish Hatchery near Irrigon, Oregon. The fish hatchery will be capable of rearing steelhead and chinook with an initial capacity of 290,000 pounds. Future expansion will allow for a total capacity of 500,000 pounds if the initial production goals are met. The hatchery will consist of both Oregon and Michigan style ponds. The Oregon ponds are similar to those at Irrigon. The Michigan ponds are more narrow and shallow, are self cleaning, and use oxygen supplementation to obtain higher rearing densities as is currently being done in the state of Michigan. The Oregon ponds are a two-pass system with the capability to convert to Michigan style ponds, if this mode of operation proves to be an effective method in the west. The Michigan ponds are three-pass with the capability to expand to four-pass.

    This document outlines regional policies and procedures for hatchery operations in the Columbia River Basin. The purpose of these policies is to provide regional guidelines by which all anadromous fish hatcheries will be operated. These policies will be adopted by the fisheries co-managers, and will provide guidance to operate hatcheries in an efficient and biologically sound manner. The hatchery policies presented in this manual are not intended to establish production priorities. Rather, the intent is to guide hatchery operations once production numbers are established. Hatchery operations discussed in this report include broodstock collection, spawning, incubation of eggs, fish rearing and feeding, fish release, equipment maintenance and operations, and personnel training. Decisions regarding production priorities must be provided by fishery managers through a comprehensive plan that addresses both natural and hatchery fish production. The Integrated Hatchery Operations Team is a multi-agency group called for by the Northwest Power Planning Council. This team was directed to develop new basinwide policies for managing and operating all existing and future anadromous fish hatcheries in the Columbia River Basin. The parties pledge to confer with each other and to use their authorities and resources to accomplish these mutually acceptable hatchery practices.

    Full Text Available This article argues that recent comparatives literatures on the welfare state have yet to adequately consider the public sector and how governments have reshaped their public services. Drawing on macro-level data from the OECD, qualitative studies, and trade union research, it is claimed that governments have substantially remade their administrative and financial procedures in order to cut expenditures and lower labour costs. It is also contended that because of financial globalization and rising debt, states have made a series of reforms to public sector industrial relations. These have worsened wages, working conditions, and jobs throughout the public sector. It is concluded that such developments are central to reforming the nature of state functioning across North America and Western Europe. This is the first study to report on government reforms to fiscal policies, public sector services, and public sector labour forces in 13 OECD countries between 1980-2005.

    Due to the construction and operation of Grand Coulee Dam (1939), anadromous salmon have been eradicated and resident fish populations permanently altered in the upper Columbia River region. Federal and private hydropower dam operations throughout the Columbia River system severely limits indigenous fish populations in the upper Columbia. Artificial production has been determined appropriate for supporting a harvestable fishery for kokanee salmon (Oncorhynchus nerka) and rainbow trout (Oncorhynchus mykiss) in Lake Roosevelt and Banks Lake (Grand Coulee Dam impoundments). A collaborative multi-agency artificial production program for the Lake Roosevelt and Banks Lake fisheries exists consisting of the Spokane Tribal Hatchery, Sherman Creek Hatchery, Ford Trout Hatchery and the Lake Roosevelt Kokanee and Rainbow Trout Net Pen Rearing Projects. These projects operate complementary of one another to target an annual release of 1 million yearling kokanee and 500,000 yearling rainbow trout for Lake Roosevelt and 1.4 million kokanee fry/fingerlings for Banks Lake. Fish produced by this project in 2004 to meet collective fish production and release goals included: 1,655,722 kokanee fingerlings, 537,783 rainbow trout fingerlings and 507,660 kokanee yearlings. Kokanee yearlings were adipose fin clipped before release. Stock composition consisted of Lake Whatcom kokanee, 50:50 diploid-triploid Spokane Trout Hatchery (McCloud River) rainbow trout and Phalon Lake red-band rainbow trout. All kokanee were marked with either thermal, oxytetracyline or fin clips prior to release. Preliminary 2004 Lake Roosevelt fisheries investigations indicate hatchery/net pen stocking significantly contributed to harvestable rainbow trout and kokanee salmon fisheries. An increase in kokanee harvest was primarily owing to new release strategies. Walleye predation, early maturity and entrainment through Grand Coulee Dam continues to have a negative impact on adult kokanee returns and limits the

    On 31 December 1991, the Chinese State Council Housing System Reform Leading Group announced this Opinion, setting out targets, principles, and policies for the reform of the system of provisional housing in urban areas. Section 1 of the Opinion provides that the long-term goal of reform is to convert the distribution of housing from a system based on welfare allocation to one based on commodity exchange either by purchase or rental. Section 2 sets the following targets for reform: a) within the period of the Eighth Five-Year Plan, the system will be converted from one of low rent to one in which the calculation of rent will be based on cost of upkeep, administration costs, and depreciation; b) by 2000, the calculation of rent will be based on the above factors, as well as interest on investment and property taxes; and c) in the long term, the calculation of rent will be based on all of the above factors, as well as land rent, insurance premiums, and profit. Section 4 deals with policies for managing various problems such as rent increases and subsidies, sales of housing, financing for housing, the system of investment in and construction of housing, and administration of housing. This Section provides that a three-level housing investment fund based on municipalities, work units, and individuals will be established.

    Bonneville Power Administration's participation with the Washington Department of Fish and Wildlife, Ford Hatchery, provides the opportunity for enhancing the recreational and subsistence kokanee fisheries in Banks Lake. The artificial production and fisheries evaluation is done cooperatively through the Spokane Hatchery, Sherman Creek Hatchery (WDFW), Banks Lake Volunteer Net Pen Project, and the Lake Roosevelt Fisheries Evaluation Program. Ford Hatchery's production, together with the Sherman Creek and the Spokane Tribal Hatchery, will contribute to an annual goal of one million kokanee yearlings for Lake Roosevelt and 1.4 million kokanee fingerlings and fry for Banks Lake. The purpose of this multi-agency program is to restore and enhance kokanee salmon and rainbow trout populations in Lake Roosevelt and Banks Lake due to Grand Coulee Dam impoundments. The Ford Hatchery will produce 9,533 lbs. (572,000) kokanee annually for release as fingerlings into Banks Lake in October. An additional 2,133 lbs. (128,000) kokanee will be transferred to net pens on Banks Lake at Electric City in October. The net pen raised kokanee will be reared through the fall, winter, and early spring to a total of 8,533 lbs and released in May. While the origin of kokanee comes from Lake Whatcom, current objectives will be to increase the use of native (or, indigenous) stocks for propagation in Banks Lake and the Upper Columbia River. Additional stocks planned for future use in Banks Lake include Lake Roosevelt kokanee and Meadow Creek kokanee. The Ford Hatchery continues to produce resident trout (80,584 lb. per year) to promote the sport fisheries in trout fishing lakes in eastern Washington (WDFW Management, Region 1). Operation and maintenance funding for the increased kokanee program was implemented in FY 2001 and scheduled to continue through FY 2010.

    Various studies suggest that sea ranching of anadromous salmonids can result in domestication (increased fitness in the hatchery program) and a loss of fitness for natural production; however, the mechanism has not been characterized adequately. We artificially spawned hatchery and wild steelhead Oncorhynchus mykiss from the Clearwater River, Idaho, reared the resulting genetically marked (at the PEPA allozyme locus) progeny (HxH, HxW from hatchery females and wild males, and WxW) in hatcheries, and tested for differences in survival, growth, early maturation, downstream migration, and adult returns. Rearing treatments were mixed (crosses reared together) and separate (crosses reared separately from each other) at the hatchery of origin for the hatchery population where smolts are produced in one year, and at a nearby hatchery employing lower rations, lower winter temperatures, and two years of rearing to more closely mimic the natural life history (natural smolt age = 2-4 years). The hatchery population had been artificially propagated for six generations at the onset of our study. We found little or no difference in survival in the hatchery but substantially higher rates of growth and subsequent downstream migration for HxH than for WxW fish. Faster growth for HxH fish resulted in greater size at release which contributed to their higher migration rate, but other as yet uncharacterized traits also affected migration since the migration difference between crosses was apparent even within size classes. Growth of WxW fish was slower in the mixed than in the separate treatment indicating that WxW fish were competitively inferior to HxH fish in the hatchery environment. Incidence of precocious males was higher for WxW than for HxH fish in the separate but not in the mixed treatment. Incidence of HxH precocious males was similar between treatments. Apparently, the presence of HxH fish suppressed high incidence of early maturation by WxW males. A direct effect beyond

    Background Creation of a hydrogen infrastructure is an important prerequisite of widespread fuel cell commercialization, especially for the automotive market. Hydrogen is an attractive fuel since it offers an opportunity to replace petroleum-based fuels, but hydrogen occurs naturally only in chemical compounds like water or hydrocarbons that must be chemically converted to produce it. While an ultimate goal is to produce hydrogen through renewable energy sources, steam methane reforming (SMR) of natural gas is currently the most economical solution to initiate the transition to a hydrogen economy. Centralized hydrogen generation using large industrial SMR plants is already in place to serve customers. Yet, because of the weight and size of cylinders needed to contain hydrogen gas or liquid, transportation of hydrogen may only be economical for short distances. Consequently, distributed natural gas reforming, which trades off the economies of scale of large plants for simplified delivery logistics, is an attractive alternative that could address immediate problems with the lack of hydrogen infrastructure.

  20. Angler harvest, hatchery return, and tributary stray rates of recycled adult summer steelhead Oncorhynchus mykiss in the Cowlitz River, Washington

    Hatchery ‘recycling’ programs have been used to increase angling opportunities by re-releasing fish into a river after they returned to a hatchery or fish trap. Recycling is intended to increase opportunities for fishermen, but this strategy could affect wild fish populations if some recycled fish remain in the river and interact with wild fish populations. To quantify hatchery return and angler harvest rates of recycled steelhead, we conducted a 2-year study on the Cowlitz River, Washington. A total of 1051 steelhead were recycled, including 218 fish that were radio-tagged. Fates of recycled steelhead were similar between years: 48.4% returned to the hatchery, 19.2% were reported captured by anglers, and 32.4% remained in the river. A multistate model quantified the effects of covariates on hatchery return and angler harvest rates, which were positively affected by river discharge and negatively affected by time since release. However, hatchery return rates increased and angler harvest rates decreased during periods of increasing discharge. A total of 21.1% (46 fish) of the radio-tagged steelhead failed to return to the hatchery or be reported by anglers, but nearly half of those fish (20 fish) appeared to be harvested and not reported. The remaining tagged fish (11.9% of the radio-tagged population) were monitored into the spawning period, but only five fish (2.3% of the radio-tagged population) entered tributaries where wild steelhead spawning occurs. Future research focused on straying behaviour, and spawning success of recycled steelhead may further advance the understanding of the effects of recycling as a management strategy.

    This report presents the results of site analysis for the Bonneville Power Administration Northeast Oregon Hatchery Project. The purpose of this project is to provide engineering services for the siting and conceptual design of hatchery facilities for the Bonneville Power Administration. The hatchery project consists of artificial production facilities for salmon and steelhead to enhance production in three adjacent tributaries to the Columbia River in northeast Oregon: the Grande Ronde, Walla Walla, and Imnaha River drainage basins. Facilities identified in the master plan include adult capture and holding facilities; spawning incubation, and early rearing facilities; full-term rearing facilities; and direct release or acclimation facilities. The evaluation includes consideration of a main production facility for one or more of the basins or several smaller satellite production facilities to be located within major subbasins. The historic and current distribution of spring and fall chinook salmon and steelhead was summarized for the Columbia River tributaries. Current and future production and release objectives were reviewed. Among the three tributaries, forty seven sites were evaluated and compared to facility requirements for water and space. Site screening was conducted to identify the sites with the most potential for facility development. Alternative sites were selected for conceptual design of each facility type. A proposed program for adult holding facilities, final rearing/acclimation, and direct release facilities was developed.

    The Umatilla Hatchery is the foundation for rehabilitating chinook salmon and enhancing summer steelhead in the Umatilla River and expected to contribute significantly to the Northwest Power Planning Council`s goal of doubling salmonid production in the Columbia Basin. This report covers the second year of comprehensive monitoring and evaluation of the Umatilla Hatchery. As both the hatchery and the evaluation study are in the early stages of implementation, much of the information contained in this report is preliminary.

    Performance of wild (W) and hatchery (H) spring Chinook salmon (Oncorhynchus tshawytscha) was evaluated for a sixth generation hatchery program. Management techniques to minimize genetic divergence from the wild stock included regular use of wild broodstock and volitional releases of juveniles. Performance of HH, WW, and HW (hatchery female spawned with wild male) crosses was compared in hatchery and stream environments. The WW juveniles emigrated from the hatchery at two to three times the rate of HH fish in the fall (HW intermediate) and 35% more HH than WW adults returned (27% more HW than WW adults). Performance in the stream did not differ statistically between HH and WW fish, but outmigrants (38% WW, 30% HW, and 32% HH fish) during the first 39 days of the 16-month sampling period composed 74% of total outmigrants. Differences among hatchery-reared crosses were partially due to additive genetic effects, were consistent with domestication (increased fitness for the hatchery population in the hatchery program), and suggested that selection against fall emigration from the hatchery was a possible mechanism of domestication.

    The recent discovery of pharmaceuticals in streams across the United States (Kolpin and others, 2002) has raised the visibility and need for monitoring of antibiotics in the environment. Possible sources of antibiotics and other pharmaceuticals in streams may include fish hatcheries. This fact sheet presents the results from a preliminary study of fish hatcheries across the United States for the occurrence and concentration of antibiotics present in fish hatchery water. The study examines both sufonamides and tetracyclines. Sulfonamides are synthetic compounds, and tetracyclines are naturally occurring compounds. The use of antibiotics added to specially formulated feed is a common practice in fish hatcheries to treat and prevent bacterial infections in large fish populations. U.S. Food and Drug Administration (FDA) approved antibiotics are oxytetracycline-HCI, sulfamerazine, and a combination drug containing ormetoprim and sulfadiamethoxine (U.S. Food and Drug Administration, 2003). During January 2001?June 2002, the U.S. Geological Survey (USGS) Organic Geochemistry Research Laboratory (OGRL), Lawrence, Kansas, cooperatively collected water samples from 13 fish hatcheries across the United States (fig. 1) with the assistance of hatchery operators. A method for the analysis of antibiotics was developed and used to identify and quantify these compounds in fish hatchery water (Lindsey and others, 2001). This study was completed to determine if trace levels of antibiotics [approximately 1 microgram per liter (?g/L) or 1 part per billion or greater occurred] in which water associated with fish hatcheries, which are a potential source of these compounds in surface water.

    An experiment was undertaken to determine the relative strength of maternal and stock effects in Chinook salmon (Oncorhynchus tshawytscha) reared in a common environment, as a companion study to our investigation of hatchery and wild Chinook salmon. Pure-strain and reciprocal crosses were made between two hatchery stocks (Carson and Warm Springs National Fish Hatcheries). The offspring were reared together in one of the hatcheries to the smolt stage, and then were transferred to a seawater rearing facility (USGS-Marrowstone Field Station). Differences in survival, growth and disease prevalence were assessed. Fish with Carson parentage grew to greater size at the hatchery and in seawater than the pure-strain Warm Springs fish, but showed higher mortality at introduction to seawater. The analyses of maternal and stock effects were inconclusive, but the theoretical responses to different combinations of maternal and stock effects may be useful in interpreting stock comparison studies.

  8. Handling and Treatment of Poultry Hatchery Waste: A Review

    Directory of Open Access Journals (Sweden)

    Belinda Rodda

    2011-01-01

    Full Text Available A literature review was undertaken to identify methods being used to handle and treat hatchery waste. Hatchery waste can be separated into solid waste and liquid waste by centrifuging or by using screens. Potential methods for treating hatchery waste on site include use of a furnace to heat the waste to produce steam to run a turbine generator or to use an in line composter to stabilise the waste. There is also potential to use anaerobic digestion at hatcheries to produce methane and fertilisers. Hatcheries disposing wastewater into lagoons could establish a series of ponds where algae, zooplankton and fish utilise the nutrients using integrated aquaculture which cleans the water making it more suitable for irrigation. The ideal system to establish in a hatchery would be to incorporate separation and handling equipment to separate waste into its various components for further treatment. This would save disposal costs, produce biogas to reduce power costs at plants and produce a range of value added products. However the scale of operations at many hatcheries is too small and development of treatment systems may not be viable.

    1996-11-01

    Autothermal fuel reforming (ATR) consists of reacting a hydrocarbon fuel such as natural gas or diesel with steam to produce a hydrogen-rich {open_quotes}reformed{close_quotes} fuel. This work has been designed to investigate the fuel reformation and the product gas combustion under gas turbine conditions. The hydrogen-rich gas has a high flammability with a wide range of combustion stability. Being lighter and more reactive than methane, the hydrogen-rich gas mixes readily with air and can be burned at low fuel/air ratios producing inherently low emissions. The reformed fuel also has a low ignition temperature which makes low temperature catalytic combustion possible. ATR can be designed for use with a variety of alternative fuels including heavy crudes, biomass and coal-derived fuels. When the steam required for fuel reforming is raised by using energy from the gas turbine exhaust, cycle efficiency is improved because of the steam and fuel chemically recuperating. Reformation of natural gas or diesel fuels to a homogeneous hydrogen-rich fuel has been demonstrated. Performance tests on screening various reforming catalysts and operating conditions were conducted on a batch-tube reactor. Producing over 70 percent of hydrogen (on a dry basis) in the product stream was obtained using natural gas as a feedstock. Hydrogen concentration is seen to increase with temperature but less rapidly above 1300{degrees}F. The percent reforming increases as the steam to carbon ratio is increased. Two basic groups of reforming catalysts, nickel - and platinum-basis, have been tested for the reforming activity.

    1996-08-01

    The Nez Perce Tribe has proposed to build and operate the Nez Perce Tribal Hatchery (NPTH) in the Clearwater River subbasin of Idaho for the purpose of restoring self-sustaining populations of spring, summer, and fall chinook salmon to their native habitats. The project comprises a combination of incubation and rearing facilities, satellite rearing facilities, juvenile and adult collection sites, and associated production and harvest management activities. As currently conceived, the NPTH program will produce approximately 768,000 spring chinook parr, 800,000 summer chinook fry, and 2,000,000 fall chinook fry on an annual basis. Hatchery fish would be spawned, reared, and released under conditions that promote wild-type characteristics, minimize genetic changes in both hatchery and wild chinook populations, and minimize undesirable ecological interactions. The primary objective is to enable hatchery-produced fish to return to reproduce naturally in the streams in which they are released. These and other characteristics of the project are described in further detail in the Nez Perce Tribal Hatchery Master Plan, the 1995 Supplement to the Master Plan, and the Nez Perce Tribal Hatchery Program Environmental Impact Statement. The report in hand is referred to in project literature as the NPTH Monitoring and Evaluation (M&E) Plan. This report describes monitoring and evaluation activities that will help NPTH managers determine whether they were successful in restoring chinook salmon populations and avoiding adverse ecological impacts.

    This report summarizes the monitoring and evaluation studies of salmonids reared at Umatilla Hatchery for the period November 1, 1995 to October 31, 1996. Studies at Umatilla Hatchery are designed to evaluate rearing of chinook salmon and steelhead in Michigan raceways. Characteristics of Michigan raceways include high fish densities, rapid water turnover, oxygen supplementation, reuse of water, and baffles designed to reduce cleaning. Fish health at Umatilla Hatchery and other facilities associated with the Umatilla program is intensively monitored and evaluated as part of the overall research project. Further, under the Integrated Hatchery Operations Team guidelines, specific requirements for fish health monitoring are mandatory and have become the responsibility of the fish health staff conducting the studies at Umatilla Hatchery. Additional studies include evaluations of sport fisheries in the Umatilla River and mass marking and straying of fall chinook salmon. Juvenile rearing experiments have been completed for subyearling fall chinook salmon reared in Michigan and Oregon raceways. Although preliminary adult return data has been recovered, the most data on post-release survival is incomplete. Conclusions in this report should be viewed as preliminary and used in conjunction with additional information as it becomes available.

    The Sherman Creek Hatchery (SCH) was designed to rear 1.7 million kokanee fry for acclimation and imprinting during the spring and early summer. Additionally, it was designed to trap all available returning adult kokanee during the fall for broodstock operations and evaluations. Since the start of this program, the operations of the SCH have been modified to better achieve program goals. These strategic changes have been the result of recommendations through the Lake Roosevelt Hatcheries Coordination Team (LRHCT) and were implemented to enhance imprinting, improve survival and operate the two kokanee facilities more effectively. The primary change has been to replace the kokanee fingerling program with a kokanee yearling (post smolt) program. The second significant change has been to rear 120,000 rainbow trout fingerling at SCH from July through October to enable the Spokane Tribal Hatchery (STH) to rear additional kokanee for the yearling program.

    Hydropower development and operations in the Columbia River basin have caused the loss of 5 million to 11 million salmonids. An interim goal of the Northwest Power Planning Council is to reestablish these historical numbers by doubling the present adult runs from 2.5 million to 5.0 million fish. This increase in production will be accomplished through comprehensive management of both wild and hatchery fish, but artificial propagation will play a major role in the augmentation process. The current husbandry techniques in existing hatcheries require improvements that may include changes in rearing densities, addition of oxygen, removal of excess nitrogen, and improvement in raceway design. Emphasis will be placed on the ability to increase the number of fish released from hatcheries that survive to return as adults.

    Bacterial disease is a significant issue for larviculture of several species of shellfish, including oysters. One source of bacteria is the seawater used throughout the hatchery. In this study carried out at a commercial oyster hatchery in Tasmania, Australia, the diversity of the bacterial community and its relationship with larval production outcomes were studied over a 2-year period using terminal restriction fragment length polymorphism and tag-encoded pyrosequencing. The bacterial communities were very diverse, dominated by the Alphaproteobacteria, Gammaproteobacteria, Flavobacteria and Cyanobacteria. The communities were highly variable on scales of days, weeks and seasons. The difference between the intake seawater and treated clean seawater used in the hatchery was smaller than the observed temporal differences in the seawater throughout the year. No clear correlation was observed between production outcomes and the overall bacterial community structure. However, one group of Cyanobacterial sequences was more abundant when mass mortality events occurred than when healthy spat were produced although they were always present.

    Spring chinook salmon populations in the Imnaha and Grande Ronde rivers are listed as threatened under the Endangered Species Act (ESA) and are at high risk of extirpation. The Nez Perce Tribe, the Confederated Tribes of the Umatilla Indian Reservation, and Oregon Department of Fish and Wildlife, are co-managers of conservation/restoration programs for Imnaha and Grande Ronde spring chinook salmon that use hatchery supplementation and conventional and captive broodstock techniques. The immediate goal of these programs is to prevent extirpation and provide the potential for restoration once factors limiting production are addressed. These programs redirect production occurring under the Lower Snake River Compensation Plan (LSRCP) from mitigation to conservation and restoration. Both the Imnaha and Grande Ronde conservation/restoration programs are described in ESA Section 10 permit applications and the co-managers refer to the fish production from these programs as the Currently Permitted Program (CPP). Recently, co-managers have determined that it is impossible to produce the CPP at Lookingglass Hatchery, the LSRCP facility intended for production, and that without additional facilities, production must be cut from these conservation programs. Development of new facilities for these programs through the Columbia Basin Fish and Wildlife Program is considered a new production initiative by the Northwest Power Planning Council (NPPC) and requires a master plan. The master plan provides the NPPC, program proponents and others with the information they need to make sound decisions about whether the proposed facilities to restore salmon populations should move forward to design. This master plan describes alternatives considered to meet the facility needs of the CPP so the conservation program can be fully implemented.

    The Northwest Power Planning Council's Columbia River Basin Fish and Wildlife Program authorized construction of Umatilla Fish Hatchery (UFH) in 1986. Measure 703 of the program amended the original authorization for the hatchery and specified evaluation of the Michigan (MI) raceways using oxygen supplementation to reach production goals of 290,000 lb of chinook salmon (Oncorhynchus tshawytscha) and steelhead (O. mykiss). The hatchery was completed in fall 1991. Partial justification for the hatchery was to evaluate new production and supplementation techniques. MI raceways at UFH increase smolt production with a limited water supply. Test results for MI raceways will have systematic application in the Columbia River basin. The UFH is the foundation for rehabilitating chinook salmon and enhancing steelhead in the Umatilla River (CTUIR and ODFW 1990) and is expected to contribute significantly to the Northwest Power Planning Council's goal of doubling salmon production in the Columbia Basin. Hatchery production goals and a comprehensive monitoring and evaluation plan were presented in the Umatilla Hatchery Master Plan (CTUIR and ODFW 1990). The Comprehensive Plan for Monitoring and Evaluation of Umatilla Hatchery (Carmichael 1990) was approved by the Northwest Power Planning Council as a critical adaptive management guide for fisheries rehabilitation in the Umatilla River. Monitoring and evaluation will be used to increase knowledge about uncertainties inherent in the fisheries rehabilitation and will complement the developing systematic monitoring and evaluation program. The monitoring and evaluation goals are: (1) Provide information and recommendations for the culture and release of hatchery fish, harvest regulations, and natural escapement to accomplish long-term natural and hatchery production goals in the Umatilla River basin that are consistent with provisions of the Council's Columbia River Basin Fish and Wildlife Program. (2) Assess the

    The dominancy of semi-wild and hatchery-reared white-spotted charr Salvelinus leucomaenis juveniles was evaluated using pair-wise enclosure tests and field stocking tests. The semi-wild S. leucomaenis originated in a hatchery, being stocked into the test stream as eyed-eggs. In the pair-wise enclosure test, the semi-wild S. leucomaenis dominated the hatchery S. leucomaenis that were of a similar standard length (L(S) ). The semi-wild S. leucomaenis were subordinate to hatchery S. leucomaenis that were > 11% larger in LS . In the field stocking test, the abundance and growth of semi-wild S. leucomaenis was decreased in the presence of larger hatchery S. leucomaenis (14% larger LS ). Taken together, these results suggest that larger hatchery S. leucomaenis ecologically suppress the smaller semi-wild S. leucomaenis. Salvelinus leucomaenis juveniles that are stocked with the intention of supplementing natural populations should be < 10% larger than their wild counterparts at the time of stocking to minimize their competitive advantage. The semi-wild and hatchery S. leucomaenis used in both tests were genetically similar individuals, suggesting that the differences are due to the early rearing environment of either a natural stream or hatchery. The hatchery S. leucomaenis have lower levels of aggression as a result of selection in the hatchery rearing environment. Rearing in a natural stream from the eyed-egg stage is likely to increase their lowered aggression.

    Federal hydropower projects as well as private power utility systems have had a devastating impact upon anadromous fish resources that once flourished in the Columbia River and it's tributaries. Several areas were completely blocked to anadromous fish by dams, causing the native people who's number one food resource was salmon to rely entirely upon resident fish to replace lost fisheries resources. The Colville Tribal Fish Hatchery is an artificial production program to partially mitigate for anadromous fish losses in the ''Blocked Area'' above Chief Joseph and Grand Coulee Dams pursuant to Resident Fish Substitution Policy of the Northwest Power Planning Councils Fish and Wildlife Program. The hatchery was accepted into the Council's Fish and Wildlife Program in 1984 as a resident fish substitution measure and the hatchery was completed in 1990. The minimum production quota for this facility is 22,679 kg (50,000 lbs.) of trout. To achieve this quota the Colville Tribal Hatchery was scheduled to produce 174,000 fingerling rainbow trout (5 grams/fish), 330,000 sub-yearling rainbow trout (15 grams/fish), 80,000 legal size rainbow trout (90 grams/fish), 196,000 fingerling brook trout (5 grams/fish), 330,000 subyearling brook trout (15 grams/fish) and 60,000 lahontan cutthroat trout (15 grams/fish) in 2001. All fish produced are released into reservation waters, including boundary waters in an effort to provide a successful subsistence /recreational fishery for Colville Tribal members as well as a successful non-member sport fishery. The majority of the fish distributed from the facility are intended to provide a ''carry-over'' fishery. Fish produced at the facility are intended to be capable of contributing to the natural production component of the reservation fish populations. Contribution to the natural production component will be achieved by producing and releasing fish of sufficient quality and quantity for

    This report consists of activities/events conducted in response to the Objectives and Tasks described in the 1999 contract Statement Of Work for the Planning and Planning and Design (P and D) and Maintenance (O and M) activities of the Nez Perce Tribal Hatchery (NPTH). The report follows the format of the contract for ease in finding accomplishments. Although specific emphasis will be placed on activities related directly to the NPTH, activities from other artificial production related projects might also be noted because of overlap in staff duties and production facilities. Additionally, the project leader's role has evolved as other Tribal fisheries projects have been developed and assigned to the Production Division, Department of Fisheries Resource Management (DFRM), and Nez Perce Tribe (NPT). Thus, implementation of the project leader role for the NPTH actually entails specific duties of the Production Division Director and the Production Division Coordinator, as well as the Hatchery Division Coordinator.

    REPORT A: UMATILLA HATCHERY MONITORING AND EVALUATION--This report summarizes monitoring and evaluation studies of salmonids reared at Umatilla Fish Hatchery (UFH) for 1 November, 1999 to 31 October, 2002. Studies at UFH are designed to evaluate rearing of chinook salmon and steelhead in ''Michigan raceways''. Characteristics of Michigan raceways include high fish densities, rapid water turnover, oxygen supplementation, reuse of water, and baffles designed to reduce cleaning. Fish health at UFH and other facilities associated with the Umatilla program are intensively monitored and evaluated along with the overall research project. Further, under the Integrated Hatchery Operations Team guidelines, specific requirements for fish health monitoring at UFH are mandatory. An experiment designed to evaluate rearing subyearling fall chinook salmon in Michigan and Oregon raceways has been completed. An evaluation of survival of subyearling fall chinook salmon reared at three densities will be completed with final returns in 2005. Two new evaluations were started during this reporting period. The first is an evaluation of spring chinook survival of groups transferred to Imeques acclimation facility in the fall, overwinter-acclimated and released with the standard acclimated production groups in March. The second is an evaluation of subyearling fall chinook survival and straying of a direct-stream released group in the lower Umatilla River and the standard group acclimated at Thornhollow acclimation facility in the upper Umatilla River. An important aspect of the project is evaluation of the spring chinook and summer steelhead fisheries in the upper and lower Umatilla River.

    This report covers the first year of comprehensive monitoring and evaluation of the Umatilla Hatchery. As both the hatchery and the evaluation study are in the early stages of implementation, much of the information contained in this report is preliminary. The most crucial data for evaluating the success of the hatchery program, the data on post-release performance and survival, is yet unavailable. In addition, several years of data are necessary to make conclusions about rearing performance at Umatilla Hatchery. The conclusions drawn in this report should be viewed as preliminary and should be used in conjunction with additional information as it becomes available. A comprehensive fish health monitoring regimen was incorporated into the monitoring and evaluation study for Umatilla Hatchery. This is a unique feature of the Umatilla Hatchery evaluation project.

    This report presents the results of site analysis for the Bonneville Power Administration Northeast Oregon Hatchery Project. The purpose of this project is to provide engineering services for the siting and conceptual design of hatchery facilities for the Bonneville Power Administration. The hatchery project consists of artificial production facilities for salmon and steelhead to enhance production in three adjacent tributaries to the Columbia River in northeast Oregon: the Grande Ronde, Walla Walla, and Imnaha River drainage basins. Facilities identified in the master plan include adult capture and holding facilities; spawning incubation, and early rearing facilities; full-term rearing facilities; and direct release or acclimation facilities. The evaluation includes consideration of a main production facility for one or more of the basins or several smaller satellite production facilities to be located within major subbasins. The historic and current distribution of spring and fall chinook salmon and steelhead was summarized for the Columbia River tributaries. Current and future production and release objectives were reviewed. Among the three tributaries, forty seven sites were evaluated and compared to facility requirements for water and space. Site screening was conducted to identify the sites with the most potential for facility development. Alternative sites were selected for conceptual design of each facility type. A proposed program for adult holding facilities, final rearing/acclimation, and direct release facilities was developed.

    1996-06-01

    This summary gives the major points of the Draft Environmental Impact Statement (EIS) prepared for the Nez Perce Tribal Hatchery by the Nez Perce Tribe (NPT), the Bonneville Power Administration (BPA), the Bureau of Indian Affairs (BIA), and other interested parties. The Nez Perce once were one of the largest Plateau tribes in the Northwest and occupied a territory that included north central Idaho, southeastern Washington and northeastern Oregon. Salmon and other migratory fish species are an invaluable food resource and an integral part of the Nez Perce Tribe`s culture. Anadromous fish have always made up the bulk of the Nez Perce tribal diet and this dependence on salmon was recognized in the treaties made with the Tribe by the US. The historic economic, social, and religious significance of the fish to the Nez Perce Tribe continues to this day, which makes the decline of fish populations in the Columbia River Basin a substantial detrimental impact to the Nez Perce way of life. The Nez Perce Tribal Hatchery is a supplementation program that would rear and release spring, summer, and fall chinook (Oncorhynchus tshawytscha), biologically similar to wild fish, to reproduce in the Clearwater River Subbasin. Program managers propose techniques that are compatible with existing aquatic and riparian ecosystems and would integrate hatchery-produced salmon into the stream and river environments needed to complete their life cycle.

    1996-06-01

    Bonneville Power Administration, the Bureau of Indian Affairs, the Nez Perce Tribe propose a supplementation program to restore chinook salmon to the Clearwater River Subbasin in Idaho. The Clearwater River is a tributary to the Snake River, which empties into the Columbia River. The Nez Perce Tribe would build and operate two central incubation and rearing hatcheries and six satellite facilities. Spring, summer and fall chinook salmon would be reared and acclimated to different areas in the Subbasin and released at the hatchery and satellite sites or in other watercourses throughout the Subbasin. The supplementation program differs from other hatchery programs because the fish would be released at different sizes and would return to reproduce naturally in the areas where they are released. Several environmental issues were identified during scoping: the possibility that the project would fail if mainstem Columbia River juvenile and adult passage problems are not solved; genetic risks to fish listed as endangered or threatened; potential impacts to wild and resident fish stocks because of increase competition for food and space; and water quality. The Proposed Action would affect several important aspects of Nez Perce tribal life, primarily salmon harvest, employment, and fisheries management.

    This report summarizes monitoring and evaluation studies of salmonids reared at Umatilla Fish Hatchery (UFH) for the period November 1, 1997 to October 31, 1998. Studies at Umatilla Hatchery are designed to evaluate rearing of chinook salmon and steelhead in ''Michigan raceways''. Characteristics of Michigan raceways include high fish densities, rapid water turnover, oxygen supplementation, reuse of water, and baffles designed to reduce cleaning. Fish health at UFH and other facilities associated with the Umatilla program are intensively monitored and evaluated as part of the overall research project. Further, under the Integrated Hatchery Operations Team guidelines, specific requirements for fish health monitoring are mandatory and have become the responsibility of the fish health staff conducting studies at UFH. Additional studies include evaluations of sport fisheries in the Umatilla River and mass marking and straying of fall chinook salmon. Except for adult recovery data, an experiment designed to evaluate rearing subyearling fall chinook salmon in Michigan and Oregon raceways has been completed. We are currently in the second year of rearing subyearling fall chinook salmon at three densities. Experimental rearing of subyearling, fall release, and yearling spring chinook salmon, and steelhead has also been conducted. Although preliminary adult return data has been recovered, data on smolt-to-adult survival for all groups is incomplete. Conclusions in this report should be viewed as preliminary and used in conjunction with additional data as it becomes available.

    No Annual Production Goals were achieved for the year. The Kalispel Hatchery experienced two episodes of brood fish mortality. The first due to a standpipe malfunction and the second attributed to gas bubble disease caused by elevated Total Dissolved Gases (TDG's) in the reservoir. To date, the hatchery has 29 brood fish in the raceway and ready to spawn. If all things go well this spring, hatchery operations should be well underway next year.

    In 1996, construction activities commenced on a largemouth bass hatchery located on the Kalispel Indian Reservation. The major construction activities were complete as of October 1997. Of the six objectives identified in the 1997 Annual Operating Plan two objectives were fully achieved: the assembly of the life support system, and the preparation of the hatchery Operations and Maintenance Manual. The remaining four objectives were not fully achieved due to the hatchery not being completed before the spawning season (spring).

    Federal hydropower projects as well as private power utility systems have had a major negative impact upon anadromous fish resources that once flourished in the Columbia River and it's tributaries. Several areas have been completely blocked to anadromous fish by dams, destroying the primary food resource (salmon) for many native people forcing them to rely heavily upon resident fish to replace these lost resources. The Colville Tribal Fish Hatchery is an artificial production program that addresses the loss of anadromous fish resources in the Upper Columbia Sub-Region within the ''blocked area'' created by the construction of Chief Joseph and Grand Coulee Dams. This project enhances resident fisheries located in the Intermountain and Columbia Cascade Provinces, specifically within the Colville Reservation portion of the Upper Columbia, SanPoil and Oakanogan Sub-Basins. The project partially mitigates for anadromous fish losses through protection/augmentation of resident fish populations to enhance fishery potential (i.e. in-place, out-of-kind mitigation) pursuant to Resident Fish Substitution Policy of the Northwest Power Planning Councils Fish and Wildlife Program. The hatchery was accepted into the Council's Fish and Wildlife Program in 1984 and the hatchery was completed in 1990. The Colville Tribal Hatchery (CTH) is located on the northern bank of the Columbia River just down stream of the town of Bridgeport, Washington that is just down stream of Chief Joseph Dam. The hatchery is located on land owned by the Colville Tribes. The minimum production quota for this facility is 22,679 kg (50,000 lbs.) of trout annually. All fish produced are released into reservation waters, including boundary waters in an effort to provide a successful subsistence/recreational fishery for Colville Tribal members and provide for a successful nonmember sport fishery.

Ten U. cordatus megalopae of each group (hatchery-reared and wild-caught were individually analyzed using a stereoscopic microscope equipped with an ocular micrometer. Length, width, and height of all megalopae were measured, and the size of body appendices was determined. The results indicate that the hatchery-reared megalopae are more robust than the wild ones. Furthermore, some significant differences in the size of certain appendices can be cues of the kind of alterations that hatchery-reared individuals experience.

    The Northwest Power Planning Council`s Columbia River Basin Fish and Wildlife Program authorized construction of the Umatilla Hatchery in 1986. Measure 703 of the program amended the original authorization for the hatchery and specified evaluation of the Michigan type of rearing using oxygen supplementation to reach production goals of 290,000 lb of chinook salmon (Oncorhynchus tshawytscha) and steelhead (Oncorhynchus nzykiss). The hatchery was completed in the fall of 1991. Partial justification for the hatchery was to develop considerable knowledge and understanding of new production and supplementation techniques. The use of the Michigan raceways in rearing at Umatilla Hatchery was selected because it could increase smolt production given the limited hatchery well water supply and allow comparison of Michigan raceways with the standard Oregon raceways. Results of testing the Michigan raceways will have systematic application in the Columbia Basin. The Umatilla Hatchery is the foundation for rehabilitating chinook salmon and enhancing steelhead in the Umatilla River and is expected to contribute significantly to the Northwest Power Planning Council`s goal of doubling salmon production in the Columbia Basin. Hatchery production goals and a comprehensive monitoring and evaluation plan were presented in the Umatilla Hatchery Master Plan .

    The Kalispel Tribal hatchery successfully spawned largemouth bass broodfish in spring 2002. Approximately 150,000 eggs were produced and hatched. These fry were started on brine shrimp for a period of ten days. At this time, the fry needed more abundance food supply. Cannibalism started and the hatchery staff transferred the remaining fry to the river in hopes that some fish would survive.

    Billions of hatchery salmon smolts are released annually in an attempt to mitigate anthropogenic impacts on freshwater habitats, often with limited success. Mortality of wild and hatchery fish is high during downstream and early ocean migration. To understand changes that occur during migration, we examined physiological and endocrine changes in Atlantic salmon (Salmo salar) smolts during hatchery rearing, downstream migration, and early ocean entry in two successive years. Gill Na+/K+-ATPase activity increased in the hatchery during spring, increased further after river release, and was slightly lower after recapture in the ocean. Plasma growth hormone levels increased in the hatchery, were higher in the river, and increased further in the ocean. Plasma IGF-I remained relatively constant in the hatchery, increased in the river, then decreased in the ocean. Plasma thyroid hormones were variable in the hatchery, but increased in both river- and ocean-captured smolts. Naturally reared fish had lower condition factor, gill NKA activity, and plasma thyroxine than hatchery fish in the river but were similar in the ocean. This novel data set provides a vital first step in understanding the role and norms of endocrine function in smolts and the metrics of successful marine entry.

    2014-12-23

    The purpose of this study was to determine the extent to which juvenile hatchery summer steelhead and wild winter steelhead overlap in space and time, to evaluate the extent of residualism among hatchery summer steelhead in the South Santiam River, and to evaluate the potential for negative ecological interactions among hatchery summer steelhead and wild winter steelhead. Because it is not possible to visually discern juvenile winter steelhead from resident rainbow trout, we treated all adipose-intact juvenile O. mykiss as one group that represented juvenile wild winter steelhead. The 2014 study objectives were to 1) estimate the proportion of hatchery summer steelhead that residualized in the South Santiam River in 2014, 2) determine the extent to which hatchery and naturally produced O. mykiss overlapped in space and time in the South Santiam River, and 3) characterize the behavioral interactions between hatchery-origin juvenile summer steelhead and naturally produced O. mykiss. We used a combination of radio telemetry and direct observations (i.e., snorkeling) to determine the potential for negative interactions between hatchery summer and wild winter steelhead juveniles in the South Santiam River. Data collected from these two independent methods indicated that a significant portion of the hatchery summer steelhead released as smolts did not rapidly emigrate from the South Santiam River in 2014. Of the 164 radio-tagged steelhead that volitionally left the hatchery, only 66 (40.2%) were detected outside of the South Santiam River. Forty-four (26.8% of 164) of the radio-tagged hatchery summer steelhead successfully emigrated to Willamette Falls. Thus, the last known location of the majority of the tagged fish (98 of 164 = 59.8%) was in the South Santiam River. Thirty-three of the tagged hatchery steelhead were detected in the South Santiam River during mobile-tracking surveys. Of those, 21 were found to be alive in the South Santiam River over three months after

The 2014 study objectives were to 1) estimate the proportion of hatchery summer steelhead that residualized in the South Santiam River in 2014, 2) determine the extent to which hatchery and naturally produced O. mykiss overlapped in space and time in the South Santiam River, and 3) characterize the behavioral interactions between hatchery-origin juvenile summer steelhead and naturally produced O. mykiss. We used a combination of radio telemetry and direct observations (i.e., snorkeling) to determine the potential for negative interactions between hatchery summer and wild winter steelhead juveniles in the South Santiam River. Data collected from these two independent methods indicated that a significant portion of the hatchery summer steelhead released as smolts did not rapidly emigrate from the South Santiam River in 2014. Of the 164 radio-tagged steelhead that volitionally left the hatchery, only 66 (40.2%) were detected outside of the South Santiam River. Forty-four (26.8% of 164) of the radio-tagged hatchery summer steelhead successfully emigrated to Willamette Falls. Thus, the last known location of the majority of the tagged fish (98 of 164 = 59.8%) was in the South Santiam River. Thirty-three of the tagged hatchery steelhead were detected in the South Santiam River during mobile-tracking surveys. Of those, 21 were found to be alive in the South Santiam River over three months after

    A 2-year study of extensive and intensive fish hatcheries was conducted to assess the general temporal occurrence of antibiotics in aquaculture. Antibiotics were detected in 15% of the water samples collected during the 2001-2002 collection period and in 31% of the samples during the 2003 collection period. Antibiotics were detected more frequently in samples from the intensive hatcheries (17 and 39%) than in samples from the extensive hatcheries (14 and 4%) during the 2001-2002 and 2003 collection periods, respectively. The maximum ormetoprim, oxytetracycline, and sulphadimethoxine concentrations were higher in samples from the intensive hatcheries (12, 10, and 36 µg L-1), respectively, than in samples from the extensive hatcheries (<0.05, 0.31, and 1.2 µg L-1), respectively. Sulphadimethoxine persisted for a longer period of time (up to 48 days) than ormetoprim (up to 28 days) and oxytetracycline (less than 20 days).

  16. Activities and Ergonomics of Workers in Broiler Hatcheries

    2015-06-01

    Full Text Available The objective this study was to assess ergonomic factors, posture and biomechanics of workers of a broiler egg hatchery. The analysis of ergonomic factors was based on physical work load, thermal environment, and exposure to light and noise. The posture of workers was analyzed using photographic records which were evaluated by the software program OWAS (Ovako Working Posture Analysing System. A biomechanics analysis was also performed based on the photographs taken of the employee at various angles, which were used as inputs to the Michigan two-dimensional biomechanical model software program. The results show that certain activities can be considered unhealthy due to the exposure of employees to physical and thermal overload. The continuous noise levels and lighting were outside the range considered adequate by the regulations of the Brazilian Ministry of Labor. The manner in which certain activities are carried out when associated with weight and poor posture can result in body lesions in broiler hatchery employees. It is therefore necessary to apply specific ergonomic programs, including scheduled breaks, training, and other measures in order to reduce or to eliminate the risks involved in these activities.

    Salvanes, A G V

    2017-01-27

    This study explores how antipredator behaviour of juvenile Atlantic salmon Salmo salar developed during conventional hatchery rearing of eggs from wild brood stock, compared with the behaviour of wild-caught juveniles from the same population. Juveniles aged 1+ years were tested in two unfamiliar environments; in one S. salar were presented with simulated predator attacks and in the other they were given the opportunity to explore an open-field arena. No difference was found in their spontaneous escape responses or ventilation rate (reflex responses) after simulated predator attacks. Hatchery-reared juveniles were more risk-prone in their behaviours than wild-caught individuals. Hatchery juveniles stayed less time in association with shelter. In the open-field arena, hatchery juveniles were more active than wild juveniles. Hatchery juveniles were also immobile for less time and spent a shorter amount of time than wild juveniles in the fringe of the open-field arena. Salmo salar size had no effect on the observed behaviour. Overall, this study provides empirical evidence that one generation of hatchery rearing does not change reflex responses associated with threats, whereas antipredator behaviour, typically associated with prior experience, was less developed in hatchery-reared than in wild individuals.

    Fidelity to high-quality spawning sites helps ensure that adults repeatedly spawn at sites that maximize reproductive success. Fidelity is also an important behavioural characteristic to consider when hatchery-reared individuals are stocked for species restoration, because artificial rearing environments may interfere with cues that guide appropriate spawning site selection. Acoustic telemetry was used in conjunction with Cormack–Jolly–Seber capture–recapture models to compare degree of spawning site fidelity of wild and hatchery-reared lake trout (Salvelinus namaycush) in northern Lake Huron. Annual survival was estimated to be between 77% and 81% and did not differ among wild and hatchery males and females. Site fidelity estimates were high in both wild and hatchery-reared lake trout (ranging from 0.78 to 0.94, depending on group and time filter), but were slightly lower in hatchery-reared fish than in wild fish. The ecological implication of the small difference in site fidelity between wild and hatchery-reared lake trout is unclear, but similarities in estimates suggest that many hatchery-reared fish use similar spawning sites to wild fish and that most return to those sites annually for spawning.

    1960-01-01

    In a study of coho salmon (Oncorhynchus kisutch), the gross chemical and histological changes occurring over a 14-month period spent in fresh water were determined. The determinations were made at 3-month intervals on: 1) hatchery-reared fish, 2) fish hatchery-reared for 3, 6, 9, and 12 months and then planted in a controlled stream for the remainder of the period; and 3) an indigenous group of wild fish in this stream. Wild fish showed high incidence of tissue damage from spinose hairs of the moth larva, Halisidota argentata. Hatchery fish were similarly affected with the severity and incidence of lesions varying directly with the time of exposure of the larvae in the wild environment. Both groups of fish were heavily parasitized by sporozoan organisms in the kidney and spinal cord. Kidney disease appeared in both wild and planted hatchery fish. The gross chemical composition of hatchery fish transformed rapidly after planting to that of the wild fish. Although the initial rate of fat loss is essentially constant for all hatchery groups after planting, fish that were hatchery reared for 9 to 12 months did not complete the transformation to the wild-type body composition by the time of downstream migration at 14 months.

    Full Text Available ABSTRACT The objective of this study was to determine the optimal inclusion level of liquid egg hatchery waste for the anaerobic co-digestion of dairy cattle manure. A completely randomized experimental was applied, with seven treatments (liquid hatchery waste to cattle manure ratios of0: 100, 5:95, 10:90, 15:85, 20:80, 25:75 and 30:70, with five replicates (batch digester model each. The evaluated variables were disappearance of total solids (TS, volatile solids (VS, and neutral detergent fiber (NDF, and specific production of biogas and of methane. Maximum TS and VS disappearance of 41.3% and 49.6%, were obtained at 15.5% and 16.0% liquid hatchery waste inclusion levels. The addition of 22.3% liquid hatchery considerably reduced NDF substrate content (53.2%. Maximum specific biogas production was obtained with 17% liquid hatchery waste, with the addition of 181.7 and 229.5 L kg-1TS and VS, respectively. The highest methane production, at 120.1 and 151.8 L CH4 kg-1TS and VS, was obtained with the inclusion of 17.5 and 18.0% liquid hatchery waste, respectively. The addition of liquid hatchery waste atratios of up to 15.5%in co-digestion with cattle manure reduced solid and fiber levels in the effluent, and improved biogas and methane production.

  2. Genetic differences in growth, migration, and survival between hatchery and wild steelhead and Chinook salmon: Introduction and executive summary

    Science.gov (United States)

    Rubin, Steve P.; Reisenbichler, Reginald; Wetzel, Lisa A.; Hayes, Michael C.

    2012-01-01

    This report presents results of studies testing for genetically based differences in performance (growth, migration, and survival) between hatchery and wild populations of steelhead and Chinook salmon (Project Number 90-052). The report is organized into 10 chapters with a general study introduction preceding the first chapter. A growing body of data shows that domestication and a resulting loss of fitness for natural rearing occur in hatchery populations of anadromous salmonids; however, the magnitude of domestication will vary among species and hatchery programs. Better information on domestication is needed to accurately predict the consequences when hatchery and wild fish interbreed. The intent of hatchery supplementation is to increase natural production through introduction of hatchery fish into natural production areas. The goal of this study was to provide managers with information on the genetic risks of hatchery supplementation to wild populations of Columbia River Basin summer steelhead and spring Chinook salmon.

    2000-01-01

    The effects of stocking hatchery trout into wild populations were studied in a Danish river, using microsatellite and mitochondrial DNA (mtDNA) markers. Baseline samples were taken from hatchery trout and wild trout assumed to be unaffected by previous stocking. Also, samples were taken from...... resident and sea trout from a stocked section of the river. Genetic differentiation between the hatchery strain and the local wild population was modest (microsatellite F-ST = 0.06). Using assignment tests, more than 90% of individuals from the baseline samples were classified correctly. Assignment tests...... to the hatchery strain suggested that interbreeding took place between hatchery and wild trout. The latter result also indicated that male hatchery trout contributed more to interbreeding than females. We suggest that stronger selection acts against stocked hatchery trout that become anadromous compared...

    This report describes the findings that have resulted from the effort to create a proposed Nez Perce Tribal Hatchery (NPTH) in northern Idaho. This effort has been undertaken because of low population densities of salmon in the Clearwater and Salmon River Basins. The Northwest Power Planning Council (Council) has approved the NPTH concept. For the NPTH to proceed, the Council must approve a master plan and amend the Columbia Basin Fish and Wildlife Program (CBFWP). Requirements of the National Environmental Policy Act (NEPA) also must be met. The goals of NPTH are to: (1) develop, increase, and reintroduce natural populations of spring, summer, and fall chinook in the Clearwater and Salmon River Basins; (2) sustain long-term preservation and genetic integrity of target fish populations; (3) keep the ecological and genetic impacts of nontarget fish populations within acceptable limits; and, (4) provide harvest opportunities for both tribal and non-tribal anglers.

    This report covers the first three years of comprehensive monitoring and evaluation of the Umatilla Hatchery. Because the hatchery and the evaluation study and the fish health monitoring investigations are in the early stages of implementation, much of the information contained in this report is preliminary. The majority of the data that is crucial for evaluating the success of the hatchery program, the data on post-release performance and survival, is yet unavailable. In addition, several years of data are necessary to make conclusions about rearing performance at Umatilla Hatchery. The conclusions drawn in this report should be viewed as preliminary and should be used in conjunction with additional information as it becomes available.

    Full Text Available Knowledge and conservation of the genetic variability in stocks maintained as live gene banks have become a high priority task for Brazilian fish culture. The aim of the present survey was to assess the transferrin allelic diversity of five hatchery stocks of tambaqui (Colossoma macropomum. The tambaqui stock from Pentecoste, the oldest maintained in Brazilian hatchery stations, retained three of the six alleles detected in wild populations of tambaqui from the Amazon River. Other hatchery stocks, directly or indirectly derived from the Pentecoste stock, did not show transferrin allelic variability. Insufficient number of founders and genetic drift due to sampling errors seem to be the main causes leading to loss of genetic diversity in tambaqui hatchery stocks. Appropriate management strategies are required in order to improve the genetic potential of tambaqui stocks in Brazil.

    It is generally held that hatchery-reared salmonids are of inferior quality and have lower smolt-to-adult survival compared to naturally-reared salmon. The overall objectives of the work performed under this contract were the following: (1) Characterize the physiology and development of naturally rearing juvenile salmonids to: (2) Allow for the design of effective rearing programs for producing wild-like smolts in supplementation and production hatchery programs. (3) Examine the relationship between growth rate and size on the physiology and migratory performance of fish reared in hatchery programs. (4) Examine the interaction of rearing temperature and feed rate on the growth and smoltification of salmon for use in producing a more wild-like smolt in hatchery programs.

    2002-04-16

    The study described in this report evaluated spawning distribution, overlap with naturally-arriving spawners, and pre-spawning mortality of spring chinook salmon, Oncorhynchus tshawytscha, outplanted as adults in the Clearwater River Subbasin in 2001. Returns of spring chinook salmon to Snake River Basin hatcheries and acclimation facilities in 2001 exceeded needs for hatchery production goals in Idaho. Consequently, management agencies including the U.S. Fish and Wildlife Service (FWS), Idaho Department of Fish and Game (IDFG) and Nez Perce Tribe (NPT) agreed to outplant chinook salmon adults as an adaptive management strategy for using hatchery adults. Adult outplants were made in streams or stream sections that have been typically underseeded with spawners. This strategy anticipated that outplanted hatchery chinook salmon would spawn successfully near the areas where they were planted, and would increase natural production. Outplanting of adult spring chinook salmon from hatcheries is likely to be proposed in years when run sizes are similar to those of the 2001 run. Careful monitoring of results from this year's outplanting can be used to guide decisions and methods for future adult outplanting. Numbers of spring chinook salmon outplanted was based on hatchery run size, hatchery needs, and available spawning habitat. Hatcheries involved in outplanting in the Clearwater Basin included Dworshak National Fish Hatchery, Kooskia National Fish Hatchery, Clearwater Anadromous Fish Hatchery, and Rapid River Fish Hatchery. The NPT, IDFG, FWS, and the National Marine Fisheries Service (NMFS) agreed upon outplant locations and a range of numbers of spring chinook salmon to be outplanted (Table 1). Outplanting occurred mainly in the Selway River Subbasin, but additional outplants were made in tributaries to the South Fork Clearwater River and the Lochsa River (Table 1). Actual outplanting activities were carried out primarily by the NPT with supplemental outplanting

    Steward, Cleveland R.

    1996-08-01

    The Nez Perce Tribe has proposed to build and operate the Nez Perce Tribal Hatchery (NPTH) in the Clearwater River subbasin of Idaho for the purpose of restoring self-sustaining populations of spring, summer, and fall chinook salmon to their native habitats. The project comprises a combination of incubation and rearing facilities, satellite rearing facilities, juvenile and adult collection sites, and associated production and harvest management activities. As currently conceived, the NPTH program will produce approximately 768,000 spring chinook parr, 800,000 summer chinook fry, and 2,000,000 fall chinook fry on an annual basis. Hatchery fish would be spawned, reared, and released under conditions that promote wild-type characteristics, minimize genetic changes in both hatchery and wild chinook populations, and minimize undesirable ecological interactions. The primary objective is to enable hatchery-produced fish to return to reproduce naturally in the streams in which they are released. These and other characteristics of the project are described in further detail in the Nez Perce Tribal Hatchery Master Plan (Larson and Mobrand 1992), the 1995 Supplement to the Master Plan (Johnson et al. 1995), and the Nez Perce Tribal Hatchery Program Environmental Impact Statement (Bonneville Power Administration et al. 1996). The report in hand is referred to in project literature as the NPTH Monitoring and Evaluation (M&E) Plan. This report describes monitoring and evaluation activities that will help NPTH managers determine. whether they were successful in restoring chinook salmon populations and avoiding adverse ecological impacts. Program success will be gauged primarily by changes in the abundance and distribution of supplemented chinook populations. The evaluation of project-related impacts will focus on the biological effects of constructing and operating NPTH hatchery facilities, introducing hatchery fish into the natural environment, and removing or displacing wild

  16. Post-Release Performance of Natural and Hatchery Subyearling Fall Chinook Salmon in the Snake and Clearwater Rivers.

    Energy Technology Data Exchange (ETDEWEB)

    Connor, William P.

    2008-04-01

    In 2006, we continued a multi-year study to compare smolt-to-adult return rate (SAR) ratios between two groups of Snake River Basin fall Chinook salmon Oncorhynchus tshawytscha that reached the sea through a combination of either (1) transportation and inriver migration or (2) bypass and inriver migration. We captured natural subyearlings rearing along the Snake and Clearwater rivers and implanted them with passive integrated transponder (PIT) tags, but knew in advance that sample sizes of natural fish would not be large enough for precise comparisons of SAR ratios. To increase sample sizes, we also cultured Lyons Ferry Hatchery subyearlings under a surrogate rearing strategy, implanted them with PIT tags, and released them into the Snake and Clearwater rivers to migrate seaward. The surrogate rearing strategy involved slowing growth at Dworshak National Fish Hatchery to match natural subyearlings in size at release as closely as possible, while insuring that all of the surrogate subyearlings were large enough for tagging (i.e., 60-mm fork length). Surrogate subyearlings were released from late May to early July 2006 to coincide with the historical period of peak beach seine catch of natural parr in the Snake and Clearwater rivers. We also PIT tagged a large representative sample of hatchery subyearlings reared under a production rearing strategy and released them into the Snake and Clearwater rivers in 2006 as part of new research on dam passage experiences (i.e., transported from a dam, dam passage via bypass, dam passage via turbine intakes or spillways). The production rearing strategy involved accelerating growth at Lyons Ferry Hatchery, sometimes followed by a few weeks of acclimation at sites along the Snake and Clearwater rivers before release from May to June. Releasing production subyearlings has been suggested as a possible alternative for making inferences on the natural population if surrogate fish were not available. Smoltto-adult return rates are not

    Tisdell, Clem; Wilson, Clevo

    2005-04-01

    By combining economic analysis of markets with ecological parameters, this article considers the role that tourism-based sea turtle hatcheries (of an open-cycle type) can play in conserving populations of sea turtles. Background is provided on the nature and development of such hatcheries in Sri Lanka. The modeling facilitates the assessment of the impacts of turtle hatcheries on the conservation of sea turtles and enables the economic and ecological consequences of tourism, based on such hatcheries, to be better appreciated. The results demonstrate that sea turtle hatcheries serving tourists can make a positive contribution to sea turtle conservation, but that their conservation effectiveness depends on the way they are managed. Possible negative effects are also identified. Economic market models are combined with turtle population survival relationships to predict the conservation impact of turtle hatcheries and their consequence for the total economic value obtained from sea turtle populations.

    During the 1990s, shellfish hatcheries operating on the Eastern Shore of Virginia noticed an increase in mortalities of their clam larvae; it was suspected that this was a result of the deteriorating quality of the estuarine water used by aquaculture hatcheries. Many hatcheries obtain their facility process water directly from nearby streams and estuaries. During the same time period, there was also an increase in the use of plastic mulch on some of the vegetable fields on the Eastern ...

    2004-04-01

    The Colville Tribal Hatchery produced 62,335 pounds of trout during the contract period, however, only 46,092 pounds were liberated to lakes and streams. The remaining production will be carried over to 2004 to be planted as larger fish into reservation waters for the lakes opener. New raceways were completed in November and brought on line in the spring. These raceways currently hold the redband rainbow brood stock and will be spawned in 2004. Efforts are continuing to capture redbands from other streams in coordination with the monitoring and evaluation program. Creel was expanded by hiring a second creel clerk to give better coverage of reservation waters by reducing travel time. Marking continues on all fish planted from CTH and refinements continue to be made. The first tag retention study has been completed and the second study is now underway to determine long term tag recognition. Lakes continue to be surveyed to complete the baseline analysis of all reservation lakes and will be completed in 2004.

    The Confederated Tribes of the Umatilla Indian Reservation (CTUIR) and Oregon Department of Fish and Wildlife (ODFW) are cooperating in a joint effort to enhance steelhead and re-establish salmon runs in the Umatilla River Basin. As an integral part of this program, Bonifer Pond, Minthorn Springs, Imeques C-mem-ini-kem and Thornhollow satellite facilities are operated for acclimation and release of juvenile summer steelhead (Oncorhynchus mykiss), fall and spring chinook salmon (O. tshawytscha) and coho salmon (O. kisutch). Minthorn is also used for holding and spawning adult summer steelhead and Three Mile Dam is used for holding and spawning adult fall chinook and coho salmon. Bonifer, Minthorn, Imeques and Thornhollow facilities are operated for acclimation and release of juvenile salmon and summer steelhead. The main goal of acclimation is to reduce stress from trucking prior to release and improve imprinting of juvenile salmonids in the Umatilla River Basin. Juveniles are transported to the acclimation facilities primarily from Umatilla and Bonneville Hatcheries. This report details activities associated with operation and maintenance of the Bonifer, Minthorn, Imeques, Thornhollow and Three Mile Dam facilities in 1996.

    The oxygen transfer columns at the Williamette Hatchery are based on a design used by the Michigan Department of Natural Resources. The geometry and internal construction of the Mlilliamette Hatchery Oxygen Transfer Columns differ from the Michigan columns in several important ways. The performance of the columns was evaluated during May, 1990. The absorption efficiency of the 24 and 30 inch Williamette Hatchery Oxygen Transfer Columns ranged from 30 to 60%, which is comparable to published information on the Michigan columns. The performance of the 24 inch Williamette Hatchery Oxygen Transfer Columns was superior to either the 30 inch columns or the Michigan columns. The yearly oxygen demand for the Williamette Hatchery oxygen supplementation project is estimated to be 31,713 lb. Based on a oxygen purity of 99.6% and oxygen costs of $0.40/100 ft{sup 3}, increasing the absorption efficiency from 50 to 75% would decrease oxygen costs of the present project by only approximately $1018/year, which is small compared to the annual project cost. The pure oxygen system at Williamette Hatchery is designed for experimental purposes, therefore the existing system is adequate its intended use. While oxygen is not a major cost in the present experimental system, it will be much more critical in full-scale applications. It was necessary to build separate columns for the Williamette Oxygen Supplementation Project, but a centralized system may be more cost-effective in larger applications. There is considerable interest in the use of the Michigan type column in the Pacific Northwest and better definition of their operating characteristics or improvement in their performance would be useful to hatchery operations. In addition, there are a number of other oxygen transfer systems that may have potential in the Pacific Northwest.

    Increasing production of hatchery salmon over the past four decades has led to concerns about possible density-dependent effects on wild Pacific salmon populations in the North Pacific Ocean. The concern arises because salmon from distant regions overlap in the ocean, and wild salmon populations having low productivity may compete for food with abundant hatchery populations. We tested the hypothesis that adult length-at-age, age-at-maturation, productivity, and abundance of a Norton Sound, Alaska, chum salmon population were influenced by Asian hatchery chum salmon, which have become exceptionally abundant and surpassed the abundance of wild chum salmon in the North Pacific beginning in the early 1980s. We found that smaller adult length-at-age, delayed age-at-maturation, and reduced productivity and abundance of the Norton Sound salmon population were associated with greater production of Asian hatchery chum salmon since 1965. Modeling of the density-dependent relationship, while controlling for other influential variables, indicated that an increase in adult hatchery chum salmon abundance from 10 million to 80 million adult fish led to a 72% reduction in the abundance of the wild chum salmon population. These findings indicate that competition with hatchery chum salmon contributed to the low productivity and abundance of Norton Sound chum salmon, which includes several stocks that are classified as Stocks of Concern by the State of Alaska. This study provides new evidence indicating that large-scale hatchery production may influence body size, age-at-maturation, productivity and abundance of a distant wild salmon population.

    Sherman Creek Hatchery's primary objective is the restoration and enhancement of the recreational and subsistence fishery in Lake Roosevelt and Banks Lake. The Sherman Creek Hatchery (SCH) was designed to rear 1.7 million kokanee fry for acclimation and imprinting during the spring and early summer. Additionally, it was designed to trap all available returning adult kokanee during the fall for broodstock operation and evaluation. Since the start of this program, the operations on Lake Roosevelt have been modified to better achieve program goals. The Washington Department of Fish and Wildlife, Spokane Tribe of Indians and the Colville Confederated Tribes form the interagency Lake Roosevelt Hatcheries Coordination Team (LRHCT) which sets goals and objectives for both Sherman Creek and the Spokane Tribal Hatchery. The LRHCT also serves to coordinate enhancement efforts on Lake Roosevelt and Banks Lake. Since 1994 the kokanee fingerling program has changed to yearling releases. By utilizing both the hatcheries and additional net pens, up to 1,000,000 kokanee yearlings can be reared and released. The construction and operation of twenty net pens in 2001 enabled the increased production. Another significant change has been to rear up to 300,000 rainbow trout fingerling at SCH from July through October, for stocking into the volunteer net pens. This enables the Spokane Tribal Hatchery (STH) to rear additional kokanee to further the enhancement efforts on Lake Roosevelt. Current objectives include increased use of native tributary stocks where available for propagation into Upper Columbia River Basin waters. The Lake Roosevelt Fisheries Evaluation Program (LRFEP) is responsible for monitoring and evaluation on the Lake Roosevelt Projects. From 1988 to 1998, the principal sport fishery on Lake Roosevelt has shifted from walleye to include rainbow trout and kokanee salmon (Underwood et al. 1997, Tilson and Scholz 1997).

    Stock enhancement, restocking and sea ranching are being increasingly applied in both fisheries and conservation. The contribution of hatchery stock to fishery harvest and the maintenance of the genetic structure of stocked populations are both important considerations when releasing captive-bred organisms into natural systems. Use of wild-caught broodstock generally overcomes some of the genetic problems associated with domesticated hatchery populations, but there is still a need to ensure that a sufficient proportion of the natural population contribute to production of the stocked cohort to realise the genetic benefits of using wild-caught broodstock. Releases of Penaeus (Melicertus) plebejus are under investigation as a means of increasing prawn production in recruitment-limited areas. We used the highly variable mitochondrial control region (mtCR) to assign post-larvae to maternal lineages in the hatchery and also to investigate the reproductive performance of female broodstock in terms of contribution to the production of the cohorts of post-larvae in the hatchery. Our data showed that mtCR can be a useful tool for tracking lineages and provided genetic evidence that unequal contribution and underproducing females can occur even in wild-caught broodstock. This work therefore highlights the importance of monitoring the genetic composition of pre-release hatchery stocks.

    One alternative reproductive tactic involving early-maturing, cryptic males is referred to as "sneaking." Although sneakers tend to be easily detectable upon close inspection, little is known about the proportion of a fish population consisting of sneakers. We examined 15,400 age-1 rainbow trout Oncorhynchus mykiss in a hatchery. Total length (mm), wet weight (g), and sex (sneaker male or unknown) were recorded for each fish. We also individually tagged each sneaker male with soft visual implant alphanumeric (VIalpha) tags that were sequentially numbered and held the fish for 25 d before inspection. Sneakers constituted 2.8% of the hatchery rainbow trout population and were smaller in total length and weight than typical rainbow trout of the same age. Retention of the VIalpha tags in sneakers was 58.9%, significantly lower than has been reported under similar circumstances. We found that sneaker males may contribute substantially to hatchery populations. Reduced tag retention in sneakers may bias studies evaluating the effect of hatchery fish on wild populations. We believe that hatchery-produced sneaker males have the potential to contribute importantly to the genetic composition of wild populations.

    Invasive crayfish are known to displace native crayfish species, alter aquatic habitat and community structure and function, and are serious pests for fish hatcheries. White River Crawfish (WRC; Procambarus acutus) were inadvertently introduced to a warm-water fish hatchery in Missouri, USA, possibly in an incoming fish shipment. We evaluated the use of chemical control for crayfish to ensure incoming and outgoing fish shipments from hatcheries do not contain live crayfish. We conducted acute (≤24 hr) static toxicity tests to determine potency, dose-response, and selectivity of pesticides to WRC, Virile Crayfish (VC; Orconectes virilis), and Fathead Minnow (FHM; Pimephales promelas). Testing identified a formulation of cypermethrin (Cynoff®) as the most potent of five pesticides evaluated for toxicity to crayfish. A 4-hr exposure to a cypermethrin concentration of 100 μg · L-1 was found to kill 100% of juvenile and adult WRC; however, adult VC were not consistently killed. Concentrations of cypermethrin ≤100 μg · L-1 did not cause significant (>10%) mortality in juvenile FHM. Additional testing is needed to examine selectivity between crayfish and hatchery fish species. Biosecurity protocols at hatcheries that use chemical control have the potential to reliably prevent inadvertent transfers of live crayfish in fish shipments.

    1989-02-01

    The kokanee Oncorhynchus nerka rehabilitation program for Lake Pend Oreille continued to show progress during 1988. Estimated kokanee abundance in early September was 10.2 million fish. This estimate is 70% higher than 1987 and 140% higher than the populations's low point in 1986. Increased population size over the past two years is the result of two consecutive strong year classes produced from high recruitment of hatchery and wild fry. High recruitment of wild fry in 1988 resulted from good parental escapement (strong year class) in 1987 and relatively high fry survival. Hatchery fry made up 51% of total fry recruitment (73% of total fry biomass), which is the largest contribution since hatchery supplementation began in the 1970s. High hatchery fry abundance resulted from a large release (13 million fry) from Cabinet Gorge Hatchery and excellent fry survival (29%) during their first summer in Lake Pend Oreille. Improved fry release strategies enhanced survival, which doubled from 1987 to 1988 and was ten times higher than survival in 1986. Our research goal is to maintain 30% survival so we are very optimistic, but need to replicate additional years to address annual variability. 27 refs., 24 figs., 3 tabs.

    Formaldehyde is commonly used to overcome contaminants introduced by hatching eggs or water supply in the hatcher cabinets. However, health risks associated with its use make economical alternatives important. This project evaluated a chlorine dioxide based product (CDBP) (0.3% concentrate) as a hatchery sanitizer in decontaminating microbial populations on the shell surface of hatching eggs (>18 d old), as well as its impact on hatchability and chick performance. Hatchers (0.20 m(2)) designed to hold approximately 50 eggs and equipped with circulation fans, heaters, and thermostats were used for the evaluation. For each of the 2 trials conducted, 450 hatching eggs were obtained and incubated in a common setter. Eggs used in trial 1 were floor eggs whereas in trial 2 nest eggs were used. On d 18 of incubation, eggs were removed from the setter, and viable eggs were randomly allocated to 9 hatchers. Pre-treatment egg rinse samples (10 eggs per hatcher) were collected for initial microbial analysis. Three hatchers were treated with CDBP and 3 hatchers with a formaldehyde based product (FBP). Three untreated hatchers served as control (C). Prior to hatch, 10 eggs/incubator, not previously rinsed, were used for post treatment microbial counts. The hatched chicks were reared until d 21 in floor pens with a common starter diet. For the CDBP treated eggs, hatchability and chick performance (weight gains, mortality, and FCR on d 7 and d 21) were similar to the other treatments. The application rate of CDBP evaluated in this study was not an effective antimicrobial alternative to formaldehyde for sanitizing hatching eggs in hatcher cabinets prior to hatch.

    Full Text Available Advances in fuel cell applications reflect the ability of reformers to produce hydrogen. This work presents a flexible micro temperature sensor that is fabricated based on micro-electro-mechanical systems (MEMS technology and integrated into a flat micro methanol reformer to observe the conditions inside that reformer. The micro temperature sensor has higher accuracy and sensitivity than a conventionally adopted thermocouple. Despite various micro temperature sensor applications, integrated micro reformers are still relatively new. This work proposes a novel method for integrating micro methanol reformers and micro temperature sensors, subsequently increasing the methanol conversion rate and the hydrogen production rate by varying the fuel supply rate and the water/methanol ratio. Importantly, the proposed micro temperature sensor adequately controls the interior temperature during oxidative steam reforming of methanol (OSRM, with the relevant parameters optimized as well.

    The Crown Point Fish Hatchery, one of several hatcheries operated by the New York State Conservation Department, is located in Crown Point Center, Essex County, on the eastern edge of the Adirondack Highlands and about 2 miles west of lake Champlain. Figure 1 is a location map of the vicinity of the Hatchery. This report summarizes an investigation by the U.S. Geological Survey, in cooperation with the New York State Conservation Department, Division of Water Resources, to locate and evaluate sources of additional ground-water supply for the Hatchery. In order to expand the facilities at the Hatchery, an additional water supply of about 100 gpm (gallons per minute) to as much as 350 gpm is needed. In addition, the type of fish culture practiced requires a water temperature of about 7 to 13 degrees Celsius (centigrade) for optimum results.

    A life history model was used to predict the response of native steelhead Oncorhynchus mykiss in the Lochsa River, Idaho, to long-term supplementation with hatchery fry and smolts. The four key factors affecting the response of the native fish to a stocking program were (1) the number of native spawners, (2) the number of stocked fish, (3) the number and fitness of progeny from stocked fish, and (4) the amount of mating between hatchery and native fish. Long-term stocking of fry or smolts led to the extinction of native fish in some scenarios. The model can be used to help assess the risks and benefits of proposed stocking programs.

    On November 20, 1991, the National Marine Fisheries Service listed Snake River sockeye salmon Oncorhynchus nerka as endangered under the Endangered Species Act of 1973. In 1991, the Idaho Department of Fish and Game, the Shoshone-Bannock Tribes, and the National Marine Fisheries Service initiated efforts to conserve and rebuild populations in Idaho. Initial steps to recover sockeye salmon included the establishment of a captive broodstock program at the Idaho Department of Fish and Game Eagle Fish Hatchery. Sockeye salmon broodstock and culture responsibilities are shared with the National Oceanic and Atmospheric Administration at two locations adjacent to Puget Sound in Washington State. Activities conducted by the Shoshone-Bannock Tribes and the National Oceanic and Atmospheric Administration are reported under separate cover. Idaho Department of Fish and Game monitoring and evaluation activities of captive broodstock program fish releases (annual report to the Bonneville Power Administration for the research element of the program) are also reported separately. Captive broodstock program activities conducted between January 1, 2004 and December 31, 2004 for the hatchery element of the program are presented in this report. In 2004, twenty-seven anadromous sockeye salmon returned to the Sawtooth Valley. Traps on Redfish Lake Creek and the upper Salmon River at the Sawtooth Fish Hatchery intercepted one and four adults, respectively. Additionally, one adult sockeye salmon was collected at the East Fork Salmon River weir, 18 were seined from below the Sawtooth Fish Hatchery weir, one adult sockeye salmon was observed below the Sawtooth Fish Hatchery weir but not captured, and two adult sockeye salmon were observed in Little Redfish Lake but not captured. Fish were captured/collected between July 24 and September 14, 2004. The captured/collected adult sockeye salmon (12 females and 12 males) originated from a variety of release strategies and were transferred to

    The Nez Perce Tribal Hatchery (NPTH) responds directly to a need to mitigate for naturally-reproducing salmon in the Clearwater River subbasin. The overall goal is to produce and release fish that will survive to adulthood, spawn in the Clearwater River subbasin and produce viable offspring that will support future natural production and genetic integrity. Several underlying purposes of fisheries management will be maintained through this program: (1) Protect, mitigate, and enhance Columbia River subbasin anadromous fish resources. (2) Develop, reintroduce, and increase natural spawning populations of salmon within the Clearwater River subbasin. (3) Provide long-term harvest opportunities for Tribal and non-Tribal anglers within Nez Perce Treaty lands within four generations (20 years) following project completion. (4) Sustain long-term fitness and genetic integrity of targeted fish populations. (5) Keep ecological and genetic impacts to non-target populations within acceptable limits. (6) Promote Nez Perce Tribal Management of Nez Perce Tribal hatchery Facilities and production areas within Nez Perce Treaty lands. Nez Perce Tribal Hatchery is a supplementation program that will rear and release spring, fall, and early-fall stocks of chinook salmon. Two life stages of spring chinook salmon will be released: parr and presmolts. Fall and early-fall chinook salmon will be released as subyearling smolts. The intent of NPTHC is to use conventional hatchery and Natural Rearing Enhancement Systems (NATURES) techniques to develop, increase and restore natural populations of spring and fall chinook salmon in the Clearwater River subbasin.

A water-soluble, heat-stable exotoxin extracted from cultures of the vibrio inhibited larval swimming and contributed to larval mortality. Although the vibrio was insensitive to penicillin in standard plate testing, this antibiotic proved useful in preventing mass larval mortalities in the hatchery.

    The Nez Perce Tribal Hatchery (NPTH) responds directly to a need to mitigate for naturally-reproducing salmon in the Clearwater River subbasin. The overall goal is to produce and release fish that will survive to adulthood, spawn in the Clearwater River subbasin and produce viable offspring that will support future natural production and genetic integrity. Several underlying purposes of fisheries management will be maintained through this program: (1) Protect, mitigate, and enhance Columbia River subbasin anadromous fish resources. (2) Develop, reintroduce, and increase natural spawning populations of salmon within the Clearwater River subbasin. (3) Provide long-term harvest opportunities for Tribal and non-Tribal anglers within Nez Perce Treaty lands within four generations (20 years) following project completion. (4) Sustain long-term fitness and genetic integrity of targeted fish populations. (5) Keep ecological and genetic impacts to non-target populations within acceptable limits. (6) Promote Nez Perce Tribal Management of Nez Perce Tribal hatchery Facilities and production areas within Nez Perce Treaty lands. Nez Perce Tribal Hatchery is a supplementation program that will rear and release spring, fall, and early-fall stocks of chinook salmon. Two life stages of spring chinook salmon will be released: parr and presmolts. Fall and early-fall chinook salmon will be released as subyearling smolts. The intent of NPTHC is to use conventional hatchery and Natural Rearing Enhancement Systems (NATURES) techniques to develop, increase and restore natural populations of spring and fall chinook salmon in the Clearwater River subbasin.

    Sherman Creek Hatchery's primary objective is the restoration and enhancement of the recreational and subsistence fishery in Lake Roosevelt and Banks Lake. The Sherman Creek Hatchery (SCH) was designed to rear 1.7 million kokanee fry for acclimation and imprinting during the spring and early summer. Additionally, it was designed to trap all available returning adult kokanee during the fall for broodstock operations and evaluations. Since the start of this program, the operations on Lake Roosevelt have been modified to better achieve program goals. The Washington Department of Fish and Wildlife, Spokane Tribe of Indians and the Colville Confederated Tribe form the interagency Lake Roosevelt Hatcheries Coordination Team (LRHCT) which sets goals and objectives for both Sherman Creek and the Spokane Tribal Hatchery and serves to coordinate enhancement efforts on Lake Roosevelt and Banks Lake. The primary changes have been to replace the kokanee fingerling program with a yearling (post smolt) program of up to 1,000,000 fish. To construct and operate twenty net pens to handle the increased production. The second significant change was to rear up to 300,000 rainbow trout fingerling at SCH from July through October, for stocking into the volunteer net pens. This enables the Spokane Tribal Hatchery (STH) to rear additional kokanee to further the enhancement efforts on Lake Roosevelt. Current objectives include increased use of native/indigenous stocks where available for propagation into Upper Columbia River Basin Waters. Monitoring and evaluation is preformed by the Lake Roosevelt Fisheries Monitoring Program. From 1988 to 1998, the principle sport fishery on Lake Roosevelt has shifted from walleye to include rainbow trout and kokanee salmon (Underwood et al. 1997, Tilson and Scholz 1997). The angler use, harvest rates for rainbow and kokanee and the economic value of the fishery has increased substantially during this 10-year period. The most recent information from

    This contract proposal is in response to the Federal Columbia River Power System Biological Opinion Implementation Plan/Update Proposed Action (UPA) associated with increasing the number of Snake River sockeye smolts by 150,000. To accomplish this proposal the cooperation and efforts of three government entities has been planned (e.g., Idaho Department of Fish and Game (IDFG), Oregon Department of Fish and Wildlife (ODFW), and the National Marine Fisheries Service (NMFS)). Improvements at the IDFG Eagle Fish Hatchery and NMFS Burley Creek Hatchery will focus on increasing sockeye salmon captive broodstock and egg production. Improvements at the ODFW Oxbow Fish Hatchery will be made to accommodate the incubation, hatching and rearing of 150,000 sockeye salmon smolts for release into Idaho's Sawtooth Valley, Upper Salmon River near IDFG's Sawtooth Fish Hatchery and/or Redfish Lake Creek 1.4 km downstream of Redfish Lake. Modifications to Oxbow Fish Hatchery (ODFW) will include retro-fit existing pond drains so pond cleaning effluent water can be routed to the pollution abatement pond, and modifications to the abatement pond. Also included in this project as an added phase, was the rerouting of the hatchery building effluent water to meet state DEQ guidelines for the use of formalin to treat salmonid eggs. Some additional funding for the described Oxbow Hatchery modifications will come from Mitchell Act Funding. All personnel costs associated with this project will come from Mitchell Act funding. Due to heavy work load issues, being under staffed, and two emergency projects in the spring and summer of 2006, ODFW engineers were not able to complete all plans and get them out for bid in 2006. As a result of these circumstances retro-fitting pond drains and modifications to the abatement pond was carried over into fiscal year 2007-2008. A no cost time extension to the contract was approved by BPA. The format for this report will follow the standard format for

    Freshwater survival in hatchery and natural rearing environments was compared between progeny of hatchery (H) and wild (W) steelhead Oncorhynchus mykiss from the Clearwater River drainage in Idaho. Adults from Dworshak National Fish Hatchery and wild adults from Fish Creek fish were artificially spawned, and their progeny were genetically marked at the PEPA allozyme locus and released together as unfed fry in production facilities at the hatchery and in Brushy Fork Creek, also in the Clearwater River drainage, in a common garden design. Survival was higher for H than for W progeny at the hatchery but lower for H than for W progeny in Brushy Fork, indicating reduced fitness of the hatchery population for natural rearing and suggesting domestication as the cause. Survival at the hatchery was lower than is typical due to disease outbreaks. Survival of the first year-class of experimental fish to smolt release was only 18%. Survival of H fish was 3.8 times that of W fish under these poor survival conditions. All fish from the second year-class died halfway through the scheduled 10 month rearing period. Survival of H fish was 5.2 times that of W fish to when 1% of the initial fry were still alive indicating that W fish succumbed to the epizootic sooner than did H fish. Emigrants from the Brushy Fork study reach were sampled for three years and fish residing in the study reach were sampled for six years following fry release. Most emigrants were one or two years old and too small to be smolts (mean fork length at age-2 = 93 mm). Survival in Brushy Fork was lower for H than for W fish of the first year-class. Survival of the second year-class was higher for H than for W fish during the first two months in the stream but was lower for H than for W fish thereafter, and net survival from release to ages 3 and older was also lower for H than for W fish if our emigrant samples were representative (periods of inoperative emigrant traps prevented certainty about this

    Full Text Available With the world moving rapidly into digital media and information, the role of higher education is becoming increasingly important. Starting in January 2008, the University of Vlora is applying a modernization agenda through setting higher standards of scholarship, accompanied by curricular and governance reforms, causing changes to happen that are shaping themselves into an era of progress and rapid development, and planting a pioneer flag in the historical timeline of Albanian higher education. Differently from all other higher education institutions in Albania, and for the first time in decades of fictitious recognition of competency, the University of Vlora is striving to detach itself from the traditional oldsystem teaching mentality and methodology, managing through many struggles to be the first public university that is uninfluenced by the pressure of corruption and nepotism, and headed towards internationalization based on western standards. In its July 2010 edition, the Ranking Web of WorldUniversities ranks University of Vlora number one among all public and private universities in Albania, a title that is well deserved and earned through genuine, untiring and unbiased efforts to reach out and aspire to be what the rankings call the best university in Albania. University of Vlora students are now studying in a university that offers updated curricula, flexible learning paths, and a fully functional automated online academic transcript system, a very productive application that combines online and batch processing to generate student transcripts, as well as to facilitate student-faculty and administration-faculty communication via a university email system. This paper explores the achievements as well as the challenges that students and professors are facing in this completely new way of learning and teaching at an institution of higher education in a post-Communist country. Data was collected using interviews, as well as open-ended and

    This report fulfills the contract obligations based on the Statement of Work (SOW) for the project as contracted with Bonneville Power Administration (BPA). Nez Perce Tribal Hatchery (NPTH) Year-2001 annual report combines information from two contracts with a combined value of $2,336,491. They are identified by Bonneville Power Administration as follows: (1) Operations and Maintenance--Project No. 1983-350-00, Contract No. 4504, and (2) Planning and Design--Project No. 1983-350-00, Contract No. 4035. The Operations and Maintenance (O&M) budget of $2,166,110 was divided as follows: Facility Development and Fish Production Costs--$860,463; and Equipment Purchases as capital cost--$1,305,647 for equipment and subcontracts. The Planning and Design (P&D) budget of $170,381 was allocated to development of a Coho master planning document in conjunction with Nez Perce Tribal Hatchery. The O&M budget expenditures represent personnel and fish production expenses; e.g., administration, management, coordination, facility development, personnel training and fish production costs for spring Chinook and Coho salmon. Under Objective 1: Fish Culture Training and Education, tribal staff worked at Clearwater Anadromous Hatchery (CAFH) an Idaho Department of Fish and Game (IDFG) facility to produce spring Chinook smolt and parr for release that are intended to provide future broodstock for NPTH. As a training exercise, BPA allowed tribal staff to rear Coho salmon at Dworshak National Fish Hatchery, a U.S. Fish and Wildlife Service (USFWS) facility. This statement of work allows this type of training to prepare tribal staff to later rear salmon at Nez Perce Tribal Hatchery under Task 1.6. As a subset of the O&M budget, the equipment purchase budget of $1,305,647 less $82,080 for subcontracts provides operational and portable equipment necessary for NPTH facilities after construction. The equipment budget for the year was $1,223,567; this year's purchases amounted $287,364.48 (see

    On November 20, 1991, the National Marine Fisheries Service listed Snake River sockeye salmon Oncorhynchus nerka as endangered under the Endangered Species Act of 1973. In 1991, the Idaho Department of Fish and Game, the Shoshone-Bannock Tribes, and the National Marine Fisheries Service initiated efforts to conserve and rebuild populations in Idaho. Initial steps to recover sockeye salmon included the establishment of a captive broodstock program at the Idaho Department of Fish and Game Eagle Fish Hatchery. Sockeye salmon broodstock and culture responsibilities are shared with the National Oceanic and Atmospheric Administration at two locations adjacent to Puget Sound in Washington State. Activities conducted by the Shoshone-Bannock Tribes and the National Oceanic and Atmospheric Administration are reported under separate cover. Idaho Department of Fish and Game monitoring and evaluation activities of captive broodstock program fish releases (annual report to the Bonneville Power Administration for the research element of the program) are also reported separately. Captive broodstock program activities conducted between January 1, 2002 and December 31, 2002 for the hatchery element of the program are presented in this report. n 2002, 22 anadromous sockeye salmon returned to the Sawtooth Valley. Fifteen of these adults were captured at adult weirs located on the upper Salmon River and on Redfish Lake Creek. Seven of the anadromous sockeye salmon that returned were observed below the Sawtooth Fish Hatchery weir and allowed to migrate upstream volitionally (following the dismantling of the weir on September 30, 2002). All adult returns were released to Redfish Lake for natural spawning. Based on their marks, returning adult sockeye salmon originated from a variety of release options. Sixty-six females from brood year 1999 and 28 females from brood year 2000 captive broodstock groups were spawned at the Eagle Hatchery in 2002. Spawn pairings produced approximately 65

    2015-01-01

    Chemical looping reforming (CLR) technology is a clean and efficient fuel conversion process for direct hydrogen production by using solid metal oxides. Instead of the traditional use of steam or pure oxygen, solid metal oxides are typically used as oxygen carriers to convert carbonaceous fuel to syngas or CO2/H2O. The reduced oxygen carrier then reacts with the steam for directly generating H2, which is separatedin situ with near zero energy consumption. Based on the need for different products and the different heat supply methods, both two-reactor and three-reactor CLR systems have been discussed, with a focus on the characteristics of oxygen carriers and reactor design. The Elingham diagram is used to compare the redox properties of various metal oxides, and to guide the selection of suitable oxygen carriers for direct hydrogen production. Recent oxygen carrier development is also discussed to investigate the strategies for improving H2 selectivity and yield. The gas solid contacting pattern should be carefully selected when designing CLR reactors with various kinds of feed fuels and target products.%化学链重整直接制氢技术使用固态金属氧化物作为氧载体代替传统重整过程中所需的水蒸气或纯氧,将燃料直接转化为高纯度的合成气或者二氧化碳和水,被还原的金属氧化物则可以与水蒸气再生并直接产生氢气,实现了氢气的近零能耗原位分离,是一种绿色高效的新型制氢过程。根据产物和供热方式的不同,可以将化学链重整直接制氢工艺分为双床系统和三床系统两类,并对各系统中氧载体与反应器的设计与选择进行了分析。通过Elingham图对不同氧载体的氧化还原能力进行比较,选取适于直接制氢的金属氧化物,并讨论了氧载体材料研发的最新进展。化学链制氢反应器设计应根据不同原料和产品的特点,选择合适的气-固接触方式,以强化化学链重整直接制氢效率。

    The main functions of the National Marine Fisheries Service (NMFS) aquaculture task biologists and contractual scientists involved in the 1978 homing studies were primarily a surveillance of fish physiology, disease, and relative survival during culture in marine net-pens, to determine if there were any unusual factors that might affect imprinting and homing behavior. The studies were conducted with little background knowledge of the implications of disease and physiology on imprinting and homing in salmonids. The health status or the stocks were quite variable as could be expected. The Dworshak and Wells Hatcheries steelhead suffered from some early stresses in seawater, probably osmoregulatory. The incidences of latent BKD in the Wells and Chelan Hatcheries steelhead and Kooskia Hatchery spring chinook salmon were extremely high, and how these will affect survival in the ocean is not known. Gill enzyme activity in the Dworshak and Chelan Hatcheries steelhead at release was low. Of the steelhead, survival in the Tucannon Hatchery stock will probably be the highest, with Dworshak Hatchery stock the lowest. This report contains the data for the narratives in Volume I.

    The program at Warm Springs National Fish Hatchery in north - central Oregon was initiated with spring Chinook salmon Oncorhynchus tshawytscha from the Warm Springs River. Managers included wild fish in the broodstock most years and avoided artificial selection to minimize genetic divergence from the wild founder population. We tested for genetic differences in survival and growth between the hatchery and wild populations to ascertain whether this goal has been achieved. Progeny of hatchery x hatchery (HH), hatchery female x wild male (HW), and wild x wild (WW) crosses were genetically marked at the sSOD - 1* allozyme locus and released together as unfed fry in hatchery ponds in 1992 and 1996 and in the Little White Salmon River, in south - central Washington, in 1996. Fish were evaluated to returning adult at the hatchery and over their freshwater residence of 16 months in the stream. The three crosses differed on several measures including survival to outmigration in the stream (WW>HH>HW) and juvenile growth in the hatchery (1992 year - class; WW>HW>HH); however, results may have been confounded. The genetic marks were found to differentially effect survival in a companion study (HH mark favored over WW mark; HW mark intermediate). Furthermore, HW survival in the current study was neither intermediate, as would be expect ed from additive genetic effects, nor similar to that of HH fish as would be expected from maternal effects since HW and HH fish were maternal half - siblings. Finally, the unexpected performance of HW fish precludes ruling out maternal differences between hatchery and wild mothers as the cause of differences between HH and WW fish. The key finding that survival of HH fish in a stream was 0.91 that for WW fish, indicating a small loss of fitness for natural rearing in the hatchery population, is valid only if three conditions hold: (1) any selection on the genetic marks was in the same direction as in the companion study, (2) lower survival in

    Based on a comparative study of China’s three-decade financial system reform and the financial reform model of Russia and selected Eastern European countries, we found noticeable discrepancies between China and other transitional countries in respect to objective setting, path and sequence selection, power sources and advancement strategy. We conclude that a "China model" of nancial system reform does exist. The formation and evolution of the "China model" is closely related to China’s special political and economic environment. More importantly, it is significantly influenced by China’s overall economic reform model as well.

    2001-03-01

    The Sherman Creek Hatchery (SCH) was designed to rear 1.7 million kokanee fry for acclimation and imprinting during the spring and early summer. Additionally, it was designed to trap all available returning adult kokanee during the fall for broodstock operations and evaluations. Since the start of this program, the operations on Lake Roosevelt have been modified to better achieve program goals. These strategic changes have been the result of recommendations through the Lake Roosevelt Hatcheries Coordination Team (LRHCT) and were done to enhance imprinting, improve survival and operate the two kokanee facilities more effectively. The primary changes have been to replace the kokanee fingerling program with a yearling (post smolt) program of up to 1,000,000 fish. To construct and operate twenty net pens to handle the increased production. The second significant change was to rear 200,000 rainbow trout fingerling at SCH from July through October, for stocking into the volunteer net pens. This enables the Spokane Tribal Hatchery (STH) to rear additional kokanee to further the enhancement efforts on Lake Roosevelt. Monitoring and evaluation is preformed by the Lake Roosevelt Fisheries Monitoring Program. From 1988 to 1998, the principle sport fishery on Lake Roosevelt has shifted from walleye to include rainbow trout and kokanee salmon (Underwood et al. 1997, Tilson and Scholz 1997). The angler use, harvest rates for rainbow and kokanee and the economic value of the fishery has increased substantially during this 10-year period. The most recent information from the monitoring program also suggests that the hatchery and net pen rearing programs have been beneficial to enhancing the Lake Roosevelt fishery while not negatively impacting wild and native stocks within the lake.

    Full Text Available The aim of this study was to assess the effect of a fish hatchery (Stocking-Breeding Centre in Goleniów -OHZ, focused on the production and on-growing of stocking material, on the quality of post-production water. The following parameters were determined: dissolved oxygen, organic matter content, buffering capacity, the concentration of some forms of nitrogen and phosphorus ((N-NH4+, N-NO2–, N-NO3-, total nitrogen, P-PO43-, total phosphorus and the concentration of chloride ions. The study also included the measurements of water temperature, electrolytic conductivity and pH. It was shown that the water supplied to the hatchery had good quality, providing optimum conditions for growth and living of fry and juvenile forms of various fish species (most indices were within the range of the first water quality class. Production activities at the hatchery caused a reduction in the quality of discharged post-production water with respect to indicators such as total suspended solids, organic matter and phosphorus.

  19. Survival of hatchery Gulf sturgeon (Acipenser oxyrinchus desotoi Mitchill, 1815) in the Suwannee River, Florida: a 19-year evaluation

    2014-01-01

    An experimental release of 1192 hatchery-reared, individually PIT tagged, 220 days old (296–337 mm TL) Gulf sturgeon, Acipenser oxyrinchus desotoi, was undertaken in 1992 in the Suwannee River, Florida. The original objectives of the 1992 release experiment were to: (1) evaluate survival rate of cultured Gulf sturgeon in the wild vs survival rate of their wild 1992 cohort counterparts, (2) determine the differential effect of release site within the river upon long-term survival, and (3) evaluate comparative growth rates of recaptured hatchery vs captured wild 1992 cohort Gulf sturgeon. The present investigation addressed those original objectives, plus an additional fourth objective: (4) evaluation of hatchery fish recapture rate change over the 19-year experiment. The primary objective was to determine efficacy of potential conservation aquaculture for this species in terms of long-term survival in the wild. Follow-up 1993–2011 gill net sampling in freshwater reaches (rkm 4–237) and the estuarine river mouth (rkm −6 to 4) yielded recaptures representing 13.0% of the total released. Mean annual hatchery fish mortality (including emigration) rate estimated for the 19-year period (1993–2011) was more than twice that for same cohort wild fish. Mark-recapture survival probability (phi) for hatchery fish, 1993–2011, was substantially lower (0.733) than for their wild counterparts (0.888). Mean annual hatchery fish recapture rate, as a percentage of all 1992 cohort fish recaptures, declined significantly after age-7, coinciding with age of onset of migration into the open Gulf of Mexico. Hypothesized causal factors may be differentially lower fitness in the marine habitat or permanent outmigration due to natal river imprinting failure. Hatchery fish recapture rates varied significantly for fish from the ten release sites, being highest near the river mouth, and lowest for the furthest upriver sites in the Suwannee River and its Santa Fe River tributary

    On November 20, 1991, the National Marine Fisheries Service listed Snake River sockeye salmon Oncorhynchus nerka as endangered under the Endangered Species Act of 1973. In 1991, the Idaho Department of Fish and Game, the Shoshone-Bannock Tribes, and the National Marine Fisheries Service initiated efforts to conserve and rebuild populations in Idaho. Initial steps to recover sockeye salmon included the establishment of a captive broodstock program at the Idaho Department of Fish and Game Eagle Fish Hatchery. Sockeye salmon broodstock and culture responsibilities are shared with the National Marine Fisheries Service at two locations adjacent to Puget Sound in Washington State. Activities conducted by the Shoshone-Bannock Tribes and the National Marine Fisheries Service are reported under separate cover. Idaho Department of Fish and Game monitoring and evaluation activities of captive broodstock program fish releases are also reported under separate cover. Captive broodstock program activities conducted between January 1, 1999 and December 31, 1999 are presented in this report. In 1999, seven anadromous sockeye salmon returned to the Sawtooth Valley and were captured at the adult weir located on the upper Salmon River. Four anadromous adults were incorporated in the captive broodstock program spawning design for year 1999. The remaining three adults were released to Redfish Lake for natural spawning. All seven adults were adipose and left ventral fin-clipped, indicating hatchery origin. One sockeye salmon female from the anadromous group and 81 females from the captive broodstock group were spawned at the Eagle Fish Hatchery in 1999. Spawn pairings produced approximately 63,147 eyed-eggs with egg survival to eyed-stage of development averaging 38.97%. Eyed-eggs (20,311), presmolts (40,271), smolts (9,718), and adults (21) were planted or released into Sawtooth Valley waters in 1999. Supplementation strategies involved releases to Redfish Lake, Redfish Lake Creek

    The Northwest Power Planning Council has established a goal of doubling the size of salmon runs in the Columbia River Basin. The achievement of this important goal is largely dependent upon expanding the production of hatchery fish. Pure oxygen has been commonly used to increase the carrying capacity of private sector salmonid hatcheries in the Pacific Northwest. The use of supplemental oxygen to increase hatchery production is significantly less expensive than the construction of new hatcheries and might save up to $500 million in construction costs.

The hatchery is dedicated to producing local strains of brown trout (Salmo trutta m. fario, grayling (Thymallus thymallus and Danube salmon (Hucho hucho for re–stocking the natural waters of the Krusnica/Una River catchments (and larger Bosnia and Herzegovina and Danube basin, support the rehabilitation of fish populations and to help revitalize local tourism. The Regional Office for Europe and Central Asia (REU of the Food and Agricultural Organization of the United Nations (FAO, based in Budapest, Hungary implements the project in close collaboration with the Sport Fishermen’s Association of Krusnica, which currently has 351 members. A fish hatchery, a pilot Recirculation Aquaculture System (RAS in the valley of the River Krusnica, is the first of its kind in Bosnia and Herzegovina. It is suitable for production of 250,000 to 450,000 fingerlings annually. Five war invalids are employed at the hatchery continuously since fish production began in November of 2008. The production technology learned by the staff abroad was adapted to the local conditions. The hatchery is expected to be self–sustainable in its operation from sale of fingerlings. Since the hatchery activity has received wider publicity, anglers’ interest in the River Krusnica and River Una has increased. Further increase in the number of visitors is expected after restocking the fish into the river, since the bigger fish populations will attract more and more anglers.

    1999-01-01

    The relationship between smoltification and smolt-to-adult return (SAR) of spring chinook salmon Oncorhynchus tshawytscha from the Deschutes River, Oregon, was examined for four release groups in each of three successive years. Fish were reared, marked with coded wire tags, and released from Round Butte Hatchery, Pelton Ladder rearing facility, and Warm Springs National Fish Hatchery. Smolt releases occurred in nearly the same place at similar times, allowing a direct comparison of SAR to several characters representing smolt quality. Return rates varied significantly among facilities, varying over an order of magnitude each year. The highest average SAR was from Pelton Ladder, the lowest was from Warm Springs. Each of the characters used as metrics of smoltification - fish size, spring growth rate (February-April), condition factor, plasma hormone concentration (thyroxine, cortisol, and insulin-like growth factor-I [IGF-I]), stress challenge, gill Na+,K+-ATPase activity, and liver glycogen concentration - varied significantly among facilities and seasonally within hatchery groups. However, only spring growth rate, gill ATPase activity, and plasma IGF-I concentration showed significant relationships to SAR. These characters and SAR itself were consistently lower for fish released from Warm Springs Hatchery than for fish from Round Butte Hatchery and Pelton Ladder. This demonstrates that differences in the quality of fish released by facilities may have profound effects on subsequent survival and suggests that manipulations of spring growth rate may be used to influence the quality of smolts released from facilities.

  7. Habitat-related predation on juvenile wild-caught and hatchery-reared red drum Sciaenops ocellatus (Linnaeus).

    2001-05-31

    We examined the patterns of habitat-specific mortality for newly settled red drum (Sciaenops ocellatus) using an experimental mesocosm approach. Experiments were designed to analyze prey vulnerability and fish rearing-type (wild-caught or hatchery-reared) in estuarine habitats of varying structural complexity including marsh (Spartina alterniflora Loisel), oyster reef (Crassostrea virginica Gmelin), seagrass (Halodule wrightii Aschers), and nonvegetated sand bottom. We used two different predators, pinfish (Lagodon rhomboides Linnaeus) and spotted seatrout (Cynoscion nebulosus Cuvier). For both predators, vulnerability of wild-caught red drum was significantly lower in structurally complex habitats such as seagrass and oyster reef; the highest vulnerability was associated with the nonvegetated bottom. This habitat effect was not apparent for hatchery-reared prey. In trials using a combination of both rearing-types, there was no significant habitat effect on prey selection, but hatchery-reared red drum suffered higher overall mortality than wild-caught fish from pinfish predators. In these trials, spotted seatrout did not select for either prey type. Differences we observed in prey vulnerability were likely caused by behavioral differences between wild-caught and hatchery-reared red drum. Our results reinforce the conclusion that structural complexity in estuarine habitats increases survival of newly settled fishes. Our data also suggest that hatchery-reared red drum may be more vulnerable to predation than natural fishes, and that survival of stocked fish may be enhanced through habitat-related behavior modification.

    1991-03-01

    Rehabilitation of kokanee Oncorhynchus nerka in Lake Pend Oreille met with some success in 1990, but unexpected results have raised new questions. Estimated kokanee abundance during late August of 1990 was about 6.9 million fish. This is a decline of 19% from 1989, a continued decrease since 1988. The decreased population was attributed to low stocking of hatchery fry (7.3 million), lower wild fry survival in 1990 (1.5%), and exceptionally poor survival of fish ages 3+ and 4+. Average survival of the older fish was only 11% in 1990 compared to 72% in prior years. Compensatory survival was noted for kokanee ages 1+ and 2+, with an average of 81% in 1990 compared to 44% in 1989. Hatchery fry comprised 47% of the total kokanee fry recruitment in 1990 (80% of fry biomass). This contribution ranked third behind 1988 and 1989 since hatchery supplementation began in the 1970s. Survival of hatchery fry was 20%, the second highest since this investigation began. Findings of 1990 indicate a more comprehensive approach to managing kokanee must take into account predator stockings and predator/prey interaction. An unexpected low adult escapement was responsible for an egg-take of only 5.6 million eggs in 1990, 58% of the previous year, which will limit experimental stocking in 1991. Modification of the fish ladder at the Cabinet Gorge Fish Hatchery to improve adult escapement is strongly recommended to increase egg-take. 27 refs., 28 figs., 6 tabs.

    This report summarizes the emigration studies of the Nez Perce Tribe in the Imnaha River subbasin during the 2001 and 2002 migration years. A migration year for the Imnaha River is defined here as beginning July 31 of the previous year and ending July 30 the following year. The conclusion of the studies at the end of migration year 2002 marked the 11th year of the Nez Perce Tribe's Lower Snake River Emigration Studies. The Nez Perce Tribe has participated in the Fish Passage Center's Smolt Monitoring Program for nine of the 11 years. These studies collect and tag juvenile chinook salmon and steelhead at two locations in the fall, rkm 74 and rkm 7, and at rkm 7 during the spring. Data from captured and tagged fish provide an evaluation of hatchery production and releases strategies, post release survival of hatchery chinook salmon, abundance of natural chinook salmon, and downstream survival and arrival timing of natural and hatchery chinook salmon and steelhead. The hydrologic conditions that migrating fish encountered in 2001 were characterized as a drought and conditions in 2002 were characterized as below average. Hatchery chinook salmon had a mean fork length that was 34 mm greater in 2001 and 35 mm greater in 2002 than the mean fork length of natural chinook smolts. Hatchery steelhead smolt mean fork lengths were 39 mm greater than natural steelhead smolts in 2001 and 44 mm greater than natural steelhead smolt fork lengths in 2002. A significant difference (p < 0.05) between hatchery and natural chinook salmon and steelhead fork lengths has been documented by these emigration studies from 1997 to 2002. Hatchery chinook salmon were volitionally released in 2001 and 2002 and the 90% arrivals for 2001 and 2002 at the lower rkm 7 trap were within the range of past observations of 22 to 38 days observed in 1999 and 2000. We estimated that 93.9% of the 123,014 hatchery chinook salmon released in 2001 survived to the lower trap and 90.2% of the 303

  12. Application of a bioenergetics model for hatchery production: Largemouth bass fed commercial diets

    2012-01-01

    Fish bioenergetics models based on natural prey items have been widely used to address research and management questions. However, few attempts have been made to evaluate and apply bioenergetics models to hatchery-reared fish receiving commercial feeds that contain substantially higher energy densities than natural prey. In this study, we evaluated a bioenergetics model for age-0 largemouth bass Micropterus salmoidesreared on four commercial feeds. Largemouth bass (n ≈ 3,504) were reared for 70 d at 25°C in sixteen 833-L circular tanks connected in parallel to a recirculation system. Model performance was evaluated using error components (mean, slope, and random) derived from decomposition of the mean square error obtained from regression of observed on predicted values. Mean predicted consumption was only 8.9% lower than mean observed consumption and was similar to error rates observed for largemouth bass consuming natural prey. Model evaluation showed that the 97.5% joint confidence region included the intercept of 0 (−0.43 ± 3.65) and slope of 1 (1.08 ± 0.20), which indicates the model accurately predicted consumption. Moreover model error was similar among feeds (P = 0.98), and most error was probably attributable to sampling error (unconsumed feed), underestimated predator energy densities, or consumption-dependent error, which is common in bioenergetics models. This bioenergetics model could provide a valuable tool in hatchery production of largemouth bass. Furthermore, we believe that bioenergetics modeling could be useful in aquaculture production, particularly for species lacking historical hatchery constants or conventional growth models.

Captive broodstock program activities conducted between January 1, 1997 and December 31, 1997 are presented in this report. One hundred twenty-six female sockeye salmon from one captive broodstock group were spawned at the Eagle Fish Hatchery in 1997. Successful spawn pairings produced approximately 148,781 eyed-eggs with a cumulative mean survival to eyed-egg rate of 57.3%. Approximately 361,600 sockeye salmon were released to Sawtooth basin waters in 1997. Reintroduction strategies included eyed-eggs (brood year 1997), presmolts (brood year 1996), and prespawn adults for volitional spawning (brood year 1994). Release locations included Redfish Lake, Alturas Lake, and Pettit Lake. During this reporting period, four broodstocks and two unique production groups were in culture at the Eagle Fish Hatchery. Two of the four broodstocks were incorporated into the 1997 spawning design, and one broodstock was terminated following

    Invasive crayfish are known to displace native crayfish species, alter aquatic habitat and community structure and function, and are serious pests for fish hatcheries. White River Crawfish (WRC; Procambarus acutus) were inadvertently introduced to a warm-water fish hatchery in Missouri, USA, possibly in an incoming fish shipment. We evaluated the use of chemical control for crayfish to ensure incoming and outgoing fish shipments from hatcheries do not contain live crayfish. We conducted acute (less than or equal to 24 hr) static toxicity tests to determine potency, dose-response, and selectivity of pesticides to WRC, Virile Crayfish (VC; Orconectes virilis), and Fathead Minnow (FHM; Pimephales promelas). Data included are: Collection location and size of test organisms; Test chemical concentrations and recovery; Mortality and effect-based responses of test organisms; Water quality of test solutions

The years 1985 to 1987 were used in this evaluation. During those years, releases averaged 143,306,596 smolts weighing 7,693,589 pounds. A total of 48 hatchery or satellite facilities were identified as having expansion capability. They were estimated to have the potential for increasing production by an 84,448,000 smolts weighing 4,853,306 pounds. 2 refs., 25 tabs.

    Shellfish hatcheries are often affected by disease outbreaks. Three such episodes were investigated in different Galician hatcheries in order to establish the relationship between present microbiota and mortalities. Isolates were obtained from various parts of the hatcheries. Experimental tests for pathogenicity were carried out in microscale experiments using selected strains on Ostrea edulis larvae. The pathogenicity of 1 strain from each outbreak was demonstrated and shown to cause high mortalities (ranging from 98.5 to 100%) in 72 to 96 h after inoculation of larval cultures. All 3 strains belong to the genus Vibrio. One of the strains was identified as Vibrio neptunius and is the first description of this species as a molluscan pathogen. The other 2 strains showed low similarity with the Vibrio species analysed and may constitute new species within this genus.

    Lake Pend Oreille once provided the most popular kokanee Oncorhynchus nerka fishery in northern Idaho. A dramatic decline in the population occurred from the mid-1960s to 1970s. Restoration efforts included construction of the Cabinet Gorge Fish Hatchery to supplement the wild population and restore the fishery. In this study, hatchery-reared age 0 kokanee were stocked into Lake Pend Oreille from 1986 through 1992. Seven experimental stocking strategies for kokanee were tested using five locations and two time periods (early May through early June or late July). In 1985, the age 3 and older kokanee totaled about 0.35 million, but rose to 0.78 million in 1986, was stable, was then followed by a decline in 1990 to 0.53 million, then improved to 1.75 million in 1992. Much of the annual variation in total numbers of kokanee, ranging from 4.5 million to 10.2 million, was due to hatchery stockings of age 0 fish. Standing stocks of kokanee remained stable and ranged from 8 to 10 kg/hectare de spite dramatic changes in density due to age 0 fish. Prior to this study (1985), standing stocks were substantially higher (mean = 13.6 kg/hectare), indicating that the population may be operating below carrying capacity. The authors found survival of age 0 hatchery kokanee by each release season to range from 3% in 1986 to 39% in 1992, while the mean from 1987 through 1992 was 23%. They found significant (P=0.05) differences in survival between years, but they could not detect differences between stocking locations (P>0.71). Their analysis of survival between time (early vs late) and location was weak and inconclusive because after 1989 they had fewer fish to stock and could not repeat testing of some release strategies. They believe some of the variation in survival between release groups each year was due to the length of time between release in the lake and trawling.

    Estimated kokanee Oncorhynchus nerka abundance in Lake Pend Oreille was 6.01 million during late summer 1987. This estimate is 40% higher than the 1986 estimate and is the second largest population estimate since 1977. Higher abundance is predominantly a result of enhanced fry survival and recruitment. Hatchery-reared fry contribution was 22% of total fry recruitment in 1987, compared to 8% in 1986, and resulted from a fivefold increase in survival. Much of this improvement can be attributed to the large (52 mm) fry produced at Cabinet Gorge Hatchery in 1987 and represents the first measurable contribution of the new hatchery to the kokanee rehabilitation program. Survival of hatchery-reared fry released into Clark Fork River was nearly one-half that of fry released into Sullivan Springs due to poor flow conditions and potentially high predation during migration from Cabinet Gorge Hatchery to Lake Pend Oreille. Wild fry survival was enhanced by early availability of forage (cladocern zooplankton) during fry emergence in late spring. Cladoceran production began three weeks earlier in 1987 than 1986, which resulted from reduced Mysis abundance and earlier thermal stratification of Lake Pend Oreille, which helped segregate cladocerans from mysid predation. Kokanee dry otolith coding was evaluated to provide a reliable long-term mark. Analysis of daily growth increments on otoliths was used successfully in 1987 to differentiate fry from various release sites. The technique will be refined during 1988 to include coding fry otoliths with water temperature fluctuations during hatchery residence. 23 refs., 20 figs., 2 tabs.

    This report summarizes the emigration studies of the Nez Perce Tribe in the Imnaha River subbasin during the 2001 and 2002 migration years. A migration year for the Imnaha River is defined here as beginning July 31 of the previous year and ending July 30 the following year. The conclusion of the studies at the end of migration year 2002 marked the 11th year of the Nez Perce Tribe's Lower Snake River Emigration Studies. The Nez Perce Tribe has participated in the Fish Passage Center's Smolt Monitoring Program for nine of the 11 years. These studies collect and tag juvenile chinook salmon and steelhead at two locations in the fall, rkm 74 and rkm 7, and at rkm 7 during the spring. Data from captured and tagged fish provide an evaluation of hatchery production and releases strategies, post release survival of hatchery chinook salmon, abundance of natural chinook salmon, and downstream survival and arrival timing of natural and hatchery chinook salmon and steelhead. The hydrologic conditions that migrating fish encountered in 2001 were characterized as a drought and conditions in 2002 were characterized as below average. Hatchery chinook salmon had a mean fork length that was 34 mm greater in 2001 and 35 mm greater in 2002 than the mean fork length of natural chinook smolts. Hatchery steelhead smolt mean fork lengths were 39 mm greater than natural steelhead smolts in 2001 and 44 mm greater than natural steelhead smolt fork lengths in 2002. A significant difference (p < 0.05) between hatchery and natural chinook salmon and steelhead fork lengths has been documented by these emigration studies from 1997 to 2002. Hatchery chinook salmon were volitionally released in 2001 and 2002 and the 90% arrivals for 2001 and 2002 at the lower rkm 7 trap were within the range of past observations of 22 to 38 days observed in 1999 and 2000. We estimated that 93.9% of the 123,014 hatchery chinook salmon released in 2001 survived to the lower trap and 90.2% of the 303

    Hatchery supplementation of steelhead Oncorhynchus mykiss raises concerns about the impacts on natural populations, including reduced growth and survival, displacement, and increased predation. The potential risks may be density dependent.We examined how hatchery stocking density and the opportunity to emigrate affect the responses of natural steelhead parr in an experimental stream channel and after 15 d found no density-dependent effects on growth, emigration, or survival at densities ranging from 1-6 hatchery parr/m2. The opportunity for steelhead parr to emigrate reduced predation by coastal cutthroat trout O. clarkii clarkii on both hatchery and natural steelhead parr. The cutthroat trout exhibited a type-I functional response (constant predation rate with increased prey density) for the hatchery and composite populations. In contrast, the predation rate on natural parr decreased as hatchery stocking density increased. Supplementation with hatchery parr at any experimental stocking density reduced the final natural parr density. This decline was explained by increased emigration fromthe supplemented groups. Natural parr had higher mean instantaneous growth rates than hatchery parr. The proportion of parr emigrating decreased as parr size increased over successive experimental trials. Smaller parr had lower survival and suffered higher predation. The final density of the composite population, a measure of supplementation effectiveness, increased with the hatchery steelhead stocking rate. Our results indicate that stocking larger hatchery parr (over 50 d postemergence) at densities within the carrying capacity would have low short-term impact on the growth, survival, and emigration of natural parr while increasing the density of the composite population; in addition, a stocking density greater than 3 fish/m2 might be a good starting point for the evaluation of parr stocking in natural streams.

    Bacillary necrosis associated with Vibrio species is the common cause of larval and spat mortality during commercial production of Australian blue mussel Mytilus galloprovincialis. A total of 87 randomly selected Vibrio isolates from various stages of rearing in a commercial mussel hatchery were characterised using partial sequences of the ATP synthase alpha subunit gene (atpA). The sequenced isolates represented 40 unique atpA genotypes, overwhelmingly dominated (98%) by V. splendidus group genotypes, with 1 V. harveyi group genotype also detected. The V. splendidus group sequences formed 5 moderately supported clusters allied with V. splendidus/V. lentus, V. atlanticus, V. tasmaniensis, V. cyclitrophicus and V. toranzoniae. All water sources showed considerable atpA gene diversity among Vibrio isolates, with 30 to 60% of unique isolates recovered from each source. Over half (53%) of Vibrio atpA genotypes were detected only once, and only 7 genotypes were recovered from multiple sources. Comparisons of phylogenetic diversity using UniFrac analysis showed that the culturable Vibrio community from intake, header, broodstock and larval tanks were phylogenetically similar, while spat tank communities were different. Culturable Vibrio associated with spat tank seawater differed in being dominated by V. toranzoniae-affiliated genotypes. The high diversity of V. splendidus group genotypes detected in this study reinforces the dynamic nature of microbial communities associated with hatchery culture and complicates our efforts to elucidate the role of V. splendidus group bacteria in vibriosis.

    Full Text Available Viral pathogens appear to exert the most significant constraints on the growth and survival of crustaceans under culture conditions. The prevalence of viral pathogens White Spot Syndrome Virus (WSSV, Hepatopancreatic Parvo Virus (HPV, Monodon Baculo Virus (MBV and Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV in Penaeus monodon post-larvae was studied. Samples collected from different hatcheries and also samples submitted by farmers from Kerala were analyzed. Out of 104 samples collected, WSSV was detected in 12.5% of the post-larvae samples. Prevalence of concurrent infections by HPV, MBV and WSSV (either dual or triple infection was present in 60.6% of the total post-larvae tested. Out of the 51 double positives, 98% showed either HPV or IHHNV infection. HPV or IHHNV was detected in 11 post-larval samples showing triple viral infection. This is the first report of IHHNV from India. Result of this study reveals the lack of efficient screening strategies to eradicate viruses in hatchery reared post-larvae.

    Full Text Available To ensure stable supply of milkfish, Chanos chanos fingerlings for stocking in ponds or cageswhere they will be reared until harvestable size, nursery production of hatchery-reared milkfish fry inearthen ponds and fed solely on natural food (periphyton was developed. Trials were conducted using500 m2 earthen ponds during the dry and wet months. The ponds were prepared and added withfertilizers in order to enhance the production of natural food. Hatchery-reared milkfish fry were stockedat densities ranging 20 – 39 fry/m2. At least a month (< 40 days after stocking, the fry reached thefingerling stage (2.59 – 4.63 g with survival rates of 68.6% - 81.0%. There was better productionduring the dry months due to abundant supply of natural food, although it was also possible to obtaingood production during the wet months when pond conditions are favorable. This strategy of rearingmilkfish fry in nursery ponds using natural food could be a viable and inexpensive technique inmaintaining sustainable milkfish aquaculture.

    The main aim of this study was to determine the occurrence of resistant bacteria in florfenicol-treated and untreated scallop larval cultures from a commercial hatchery and to characterize some selected florfenicol-resistant strains. Larval cultures from untreated and treated rearing tanks exhibited percentages of copiotrophic bacteria resistant to florfenicol ranging from 0.03% to 10.67% and 0.49-18.34%, respectively, whereas florfenicol resistance among oligotrophic bacteria varied from 1.44% to 35.50% and 3.62-95.71%, from untreated and treated larvae, respectively. Florfenicol resistant microbiota from reared scallop larvae mainly belonged to the Pseudomonas and Pseudoalteromonas genus and were mainly resistant to florfenicol, chloramphenicol, streptomycin and co-trimoxazole. This is the first study reporting antimicrobial resistant bacteria associated to a shellfish hatchery and the results suggest that a continuous surveillance of antimicrobial resistance even in absence of antibacterial therapy is urgently required to evaluate potential undesirable consequences on the surrounding environments.

    Bacterial diseases are a major cause of larval mortality in shellfish hatcheries. Even with proper sanitation measures, bacterial pathogens cannot be eliminated in all cases. The pathogenicity of bacteria isolated from Pacific Northwest shellfish hatcheries to Pacific oyster Crassostrea gigas larvae was investigated. We found 3 highly pathogenic strains and 1 mildly pathogenic strain among 33 isolates tested. These strains appear to be members of the genus Vibrio. Although there have been many studies of bivalve bacterial pathogens, a standard method to assess bacterial pathogenicity in bivalve larvae is needed. Thus, we developed 2 methods using either 15 ml conical tubes or tissue culture plates that were employed for rapidly screening bacterial strains for pathogenicity to Pacific oyster larvae. The tissue culture plates worked well for screening both mildly pathogenic strains and LD50 (lethal dose) assays. This method allowed for non-intrusive and non-destructive observation of the oyster larvae with a dissecting microscope. The LD50 for the 3 highly pathogenic strains ranged between 1.6 and 3.6 x 10(4) colony forming units (CFU) ml(-1) after 24 h and between 3.2 x 102 and 1.9 x 10(3) CFU ml(-1) after 48 h.

    INTRODUCTION The Nisqually Fall Chinook population is one of 27 stocks in the Puget Sound evolutionarily significant unit listed as threatened under the federal Endangered Species Act (ESA). Preservation and extensive restoration of the Nisqually delta ecosystem are planned to assist in recovery of the stock. A pre-restoration baseline including life history types, estuary residence time, growth rates, and habitat use are needed to evaluate the potential response of hatchery and wild Chinook salmon to restoration. Otolith analysis has been selected as a means to examine Chinook salmon life history, growth, and residence in the Nisqually estuary. Over time, the information from the otolith analyses will be used to: 1) determine if estuary restoration actions cause changes to the population structure (i.e. frequency of the different life history trajectories) for Nisqually River Chinook, 2) compare pre- and post- restoration residence times and growth rates, 3) suggest whether estuary restoration yields substantial benefits for Chinook salmon through (1) and (2), and 4) compare differences in habitat use between hatchery and wild Chinook to further protect ESA listed stock. Otoliths are calcium carbonate structures in the inner ear that grow in proportion to the overall growth of the fish. Daily growth increments can be measured so date and fish size at various habitat transitions can be back-calculated. Careful analysis of otolith microstructure can be used to determine the number of days that a fish resided in the estuary as a juvenile (increment counts), size at entrance to the estuary, size at egress, and the amount that the fish grew while in the estuary. Juvenile hatchery Chinook salmon are generally released as smolts that move quickly through the delta with much shorter residence times than for many wild fish and are not dependent on the delta as nursery habitat (Myers and Horton 1982; Mace 1983; Levings et al. 1986). The purpose of this study is to use and

    2015-12-22

    A non-catalytic recuperative reformer has a flue gas flow path for conducting hot flue gas from a thermal process and a reforming mixture flow path for conducting a reforming mixture. At least a portion of the reforming mixture flow path is embedded in the flue gas flow path to permit heat transfer from the hot flue gas to the reforming mixture. The reforming mixture flow path contains substantially no material commonly used as a catalyst for reforming hydrocarbon fuel (e.g., nickel oxide, platinum group elements or rhenium), but instead the reforming mixture is reformed into a higher calorific fuel via reactions due to the heat transfer and residence time. In a preferred embodiment, extended surfaces of metal material such as stainless steel or metal alloy that are high in nickel content are included within at least a portion of the reforming mixture flow path.

    China's telecom sector has experienced decade-long reform and market opening. The reform and prospects of China's telecom service industry are analysed in 4aspects: infrastructure development, industrial restructuring and regulation, market structure, and market opening. A competitive market has been preliminarily shaped, and its infrastructure is well advanced; but the market regulatory system and foreign direct investment is still rather inadequate. To meet WTO commitments, first priority must be given to improving regulatory system and further relaxing FDI restrictions.

  15. Reformer Fuel Injector

    Suder, Jennifer L.

    2004-01-01

    Today's form of jet engine power comes from what is called a gas turbine engine. This engine is on average 14% efficient and emits great quantities of green house gas carbon dioxide and air pollutants, Le. nitrogen oxides and sulfur oxides. The alternate method being researched involves a reformer and a solid oxide fuel cell (SOFC). Reformers are becoming a popular area of research within the industry scale. NASA Glenn Research Center's approach is based on modifying the large aspects of industry reforming processes into a smaller jet fuel reformer. This process must not only be scaled down in size, but also decrease in weight and increase in efficiency. In comparison to today's method, the Jet A fuel reformer will be more efficient as well as reduce the amount of air pollutants discharged. The intent is to develop a 10kW process that can be used to satisfy the needs of commercial jet engines. Presently, commercial jets use Jet-A fuel, which is a kerosene based hydrocarbon fuel. Hydrocarbon fuels cannot be directly fed into a SOFC for the reason that the high temperature causes it to decompose into solid carbon and Hz. A reforming process converts fuel into hydrogen and supplies it to a fuel cell for power, as well as eliminating sulfur compounds. The SOFC produces electricity by converting H2 and CO2. The reformer contains a catalyst which is used to speed up the reaction rate and overall conversion. An outside company will perform a catalyst screening with our baseline Jet-A fuel to determine the most durable catalyst for this application. Our project team is focusing on the overall research of the reforming process. Eventually we will do a component evaluation on the different reformer designs and catalysts. The current status of the project is the completion of buildup in the test rig and check outs on all equipment and electronic signals to our data system. The objective is to test various reformer designs and catalysts in our test rig to determine the most

    This paper presents the optimisation of Lime-Soda process parameters for the reduction of hardness in aqua-hatchery practices in the context of M. rosenbergii. The fresh water in the development of fisheries needs to be of suitable quality. Lack of desirable quality in available fresh water is generally the confronting restraint. On the Indian subcontinent, groundwater is the only source of raw water, having varying degree of hardness and thus is unsuitable for the fresh water prawn hatchery practices (M. rosenbergii). In order to make use of hard water in the context of aqua-hatchery, Lime-Soda process has been recommended. The efficacy of the various process parameters like lime, soda ash and detention time, on the reduction of hardness needs to be examined. This paper proposes to determine the parameter settings for the CIFE well water, which is pretty hard by using Taguchi experimental design method. Orthogonal Arrays of Taguchi, Signal-to-Noise Ratio, the analysis of variance (ANOVA) have been applied to determine their dosage and analysed for their effect on hardness reduction. The tests carried out with optimal levels of Lime-Soda process parameters confirmed the efficacy of the Taguchi optimisation method. Emphasis has been placed on optimisation of chemical doses required to reduce the total hardness using Taguchi method and ANOVA, to suit the available raw water quality for aqua-hatchery practices, especially for fresh water prawn M. rosenbergii.

    Mid-water trawling techniques were used during September to estimate kokanee population abundance, structure and survival. Abundance in 1985 was estimated at 4.5 million fish (198 per hectare), down from over 12 million kokanee in 1974 when the population was first monitored. Hatchery fry production (<6 million annually) has stabilized kokanee abundance since its initial decline in the late 1960s. Wild fry recruitment has remained relatively stable at 1.8 million since 1978; whereas recruitment of hatchery-reared fry has ranged from 0.09 to 1.98 million. The 1985 creel survey indicated that kokanee harvest rates remain low, with approximately one kokanee harvested per hour of effort from April to August. Catch rates were as high as 3.5 fish per hour during the mid-1960s. The zooplankton community was monitored with periodic plankton tows. Zooplankton composition in 1985 was similar to previous years and appears to have stabilized following the introduction of mysids, with peak cladoceran production occurring several weeks after peak kokanee emergence. Delayed release of hatchery fry resulted in higher survival of hatchery (7.3%) than wild (0.43%) kokanee fry. Other release strategies will be tested as more fry become available.

    The high loss of newly released hatchery-reared European lobster (Homarus gammarus) juveniles for stock enhancement is believed to be the result of maladaptive anti-predator behaviour connected to deprived stimuli in the hatchery environment. Our objective was to learn if an enriched hatchery environment enhances shelter-seeking behaviour and survival. In the "naïve" treatment, the juveniles were raised in single compartments without substrate and shelter whereas juveniles in the "exposed" treatment experienced substrate, shelter and interactions with conspecifics. Three experiments with increasing complexity were conducted. Few differences in shelter-seeking behaviour were found between treatments when one naïve or one exposed juvenile were observed alone. When observing interactions between one naïve and one exposed juvenile competing for shelter, naïve juveniles more often initiated the first aggressive encounter. The third experiment was set up to simulate a release for stock enhancement. Naïve and exposed juveniles were introduced to a semi-natural environment including substrate, a limited number of shelters and interactions with conspecifics. Shelter occupancy was recorded three times during a period of 35 days. Exposed juveniles occupied more shelters, grew larger and had higher survival compared with naïve juveniles. Our results demonstrate that experience of environmental complexity and social interactions increase shelter-seeking ability and survival in hatchery reared lobster juveniles.

    Many conservation programs consider translocation of turtle nests to hatcheries as a useful technique. The repeated use of the same incubation substrate over several seasons in these hatcheries could, however, be harmful to embryos if pathogens were able to accumulate or if the physical and chemical characteristics of the incubation environment were altered. However, this hypothesis has yet to be tested. We conducted two field experiments to evaluate the effects of hatchery sand and eggshell decay on the embryonic development of leatherback sea turtle eggs in Colombia. We identified the presence of both fungi and bacteria species on leatherback turtle eggs. Sea turtle eggs exposed to previously used hatchery substrates or to decaying eggshells during the first and middle third of the embryonic development produced hatchlings that were smaller and/or weighed less than control eggs. However, this did not negatively influence hatching success. The final third of embryonic development seems to be less susceptible to infection by microorganisms associated with decaying shells. We discuss the mechanisms that could be affecting sea turtle egg development when in contact with fungi. Further studies should seek to understand the infection process and the stages of development in which the fungi are more virulent to the eggs of this critically endangered species.

    The high loss of newly released hatchery-reared European lobster (Homarus gammarus) juveniles for stock enhancement is believed to be the result of maladaptive anti-predator behaviour connected to deprived stimuli in the hatchery environment. Our objective was to learn if an enriched hatchery environment enhances shelter-seeking behaviour and survival. In the “naïve” treatment, the juveniles were raised in single compartments without substrate and shelter whereas juveniles in the “exposed” treatment experienced substrate, shelter and interactions with conspecifics. Three experiments with increasing complexity were conducted. Few differences in shelter-seeking behaviour were found between treatments when one naïve or one exposed juvenile were observed alone. When observing interactions between one naïve and one exposed juvenile competing for shelter, naïve juveniles more often initiated the first aggressive encounter. The third experiment was set up to simulate a release for stock enhancement. Naïve and exposed juveniles were introduced to a semi-natural environment including substrate, a limited number of shelters and interactions with conspecifics. Shelter occupancy was recorded three times during a period of 35 days. Exposed juveniles occupied more shelters, grew larger and had higher survival compared with naïve juveniles. Our results demonstrate that experience of environmental complexity and social interactions increase shelter-seeking ability and survival in hatchery reared lobster juveniles. PMID:27560932

    Mitigation Objective 1: Produce Native Westslope Cutthroat Trout at Creston NFH--Task: Acquire eggs and rear up to 100,000 Westslope Cutthroat trout annually for offsite mitigation stocking. Accomplishments: A total of 150,000 westslope cutthroat eggs (M012 strain) were acquired from the State of Montana Washoe Park State Fish Hatchery in July 2001 for this objective. Another 120,000 westslope cutthroat eggs were taken from feral fish at Rogers Lake in May of 2001 by the Creston Hatchery crew. The fish were reared using approved fish culture techniques as defined in the U.S. Department of the Interior Fish Hatchery Management guidelines. Post release survival and angler success is monitored annually by Montana Fish Wildlife and Parks (MFWP) and the Confederated Salish and Kootenai Tribe (CSKT). Stocking numbers and locations may vary yearly based on results of biological monitoring. Mitigation Objective 2: Produce Rainbow Trout at Creston NFH--Task: Acquire and rear up to 100,000 Rainbow trout annually for offsite mitigation in closed basin waters. Accomplishments: A total of 50,500 rainbow trout eggs (Arlee strain) were acquired from the State of Montana Arlee State Fish Hatchery in December 2001 for this objective. The fish were reared using approved fish culture techniques as defined in the U.S. Department of the Interior Fish Hatchery Management guidelines. Arlee rainbow trout are being used for this objective because the stocking locations are terminal basin reservoirs and habitat conditions and returns to creel are unsuitable for native cutthroat. Post release survival and angler success is monitored annually by the Confederated Salish and Kootenai Tribe (CSKT). Stocking numbers and locations may vary yearly based on results of biological monitoring.

    Full Text Available Protocol for hatchery culture of the pullet carpet shell clam Venerupis corrugata spat is currently under development, as the only reliable means of providing spat to replenish natural beds or to support aquaculture activities. Among other variables, the microbiota has been demonstrated to be critical for successful bivalve culture. Shellfish hatcheries are hindered by fatal outbreaks of disease, regardless the bivalve species. These mass mortalities are mainly caused by opportunistic bacteria belonging to genus Vibrio and constitute one bottleneck for this economic activity. Different species, as V. tubiashii, V. pectenicida, V. splendidus, V. neptunius, V. ostreicida and V. bivalvicida, have been identified as responsible of mortalities in hatchery-reared larvae, affecting a wide range of bivalves. This is the first report of the microbiota associated with larval cultures of the pullet carpet shell clam. We present the results of the microbiological analyses of two larval cultures of pullet carpet shell reared in the Centro de Investigacións Mariñas (CIMA, Xunta de Galicia de Ribadeo (Galicia, NW Spain following the procedures developed in the institution. Each batch, A and B, was obtained from broodstocks collected in natural environment but in different geographical locations, the stock A (SW Galicia and the stock B (NW Galicia. Previous records of mortalities led us to divide each batch in two. One sub-batch (A1 and B1 was cultured following the routine procedures. Antibiotic was experimentally added to the other sub-batch (A2 and B2 with the aim of evaluating the effects on the culturable bacterial population (total marine bacteria and presumptive vibrios and on larval survival. Chloramphenicol, formerly the most commonly used antibiotic in bivalve hatcheries, was supplied with each change of seawater during larval development. Microbiological samples of broodstock, larvae and seawater in culture tanks were taken and processed

    On November 20, 1991, the National Marine Fisheries Service listed Snake River sockeye salmon Oncorhynchus nerka as endangered under the Endangered Species Act of 1973. In 1991, the Idaho Department of Fish and Game, the Shoshone-Bannock Tribes, and the National Marine Fisheries Service initiated efforts to conserve and rebuild populations in Idaho. Initial steps to recover sockeye salmon included the establishment of a captive broodstock program at the Idaho Department of Fish and Game Eagle Fish Hatchery. Sockeye salmon broodstock and culture responsibilities are shared with the National Marine Fisheries Service at two locations adjacent to Puget Sound in Washington State. Activities conducted by the Shoshone-Bannock Tribes and the National Marine Fisheries Service are reported under separate cover. Idaho Department of Fish and Game monitoring and evaluation activities of captive broodstock program fish releases are also reported under separate cover. Captive broodstock program activities conducted between January 1, 2000 and December 31, 2000 are presented in this report.

    Rahul Srivastava

    Full Text Available The well-known Late Cretaceous Lameta Ghat locality (Jabalpur, India provides a window of opportunity to study a large stable, near shore sandy beach, which was widely used by sauropod dinosaurs as a hatchery. In this paper, we revisit the eggs and eggshell fragments previously assigned to lizards from this locality and reassign them to crocodylomorphs. Several features point to a crocodilian affinity, including a subspherical to ellipsoidal shape, smooth, uneven external surface, discrete trapezoid shaped shell units with wide top and narrow base, basal knobs and wedge shaped crystallites showing typical inverted triangular extinction under crossed nicols. The crocodylomorph eggshell material presented in this paper adds to the skeletal data of these most probably Cretaceous-Eocene dryosaurid crocodiles.

    Four lytic bacteriophages designated as φVh1, φVh2, φVh3, and φVh4 were isolated from commercial shrimp hatcheries, possessing broad spectrum of infectivity against luminescent Vibrio harveyi isolates, considering their potential as biocontrol agent of luminescent bacterial disease in shrimp hatcheries, and were characterized by electron microscopy, genomic analysis, restriction enzyme analysis (REA), and pulsed-field gel electrophoresis (PFGE). Three phages φVh1, φVh2, and φVh4 had an icosahedral head of 60-115 nm size with a long, noncontractile tail of 130-329 × 1-17 nm, belonged to the family Siphoviridae. φVh3 had an icosahedral head (72 ± 5 nm) with a short tail (27 × 12 nm) and belonged to Podoviridae. REA with DraI and PFGE of genomic DNA digested with ScaI and XbaI and cluster analysis of their banding patterns indicated that φVh3 was distinct from the other three siphophages. PFGE-based genome mean size of the four bacteriophages φVh1, φVh2, φVh3, and φVh4 was estimated to be about 85, 58, 64, and 107 kb, respectively. These phages had the property of generalized transduction as demonstrated by transduction with plasmid pHSG 396 with frequencies ranging from 4.1 × 10(-7) to 2 × 10(-9) per plaque-forming unit, suggesting a potential ecological role in gene transfer among aquatic vibrios.

  8. Nutritional Supplement of Hatchery Eggshell Membrane Improves Poultry Performance and Provides Resistance against Endotoxin Stress.

    Full Text Available Eggshells are significant part of hatchery waste which consist of calcium carbonate crust, membranes, and proteins and peptides of embryonic origins along with other entrapped contaminants including microbes. We hypothesized that using this product as a nutritional additive in poultry diet may confer better immunity to the chickens in the paradigm of mammalian milk that enhances immunity. Therefore, we investigated the effect of hatchery eggshell membranes (HESM as a short term feed supplement on growth performance and immunity of chickens under bacterial lipopolysaccharide (LPS challenged condition. Three studies were conducted to find the effect of HESM supplement on post hatch chickens. In the first study, the chickens were fed either a control diet or diets containing 0.5% whey protein or HESM as supplement and evaluated at 5 weeks of age using growth, hematology, clinical chemistry, plasma immunoglobulins, and corticosterone as variables. The second and third studies were done to compare the effects of LPS on control and HESM fed birds at 5 weeks of age following at 4 and 24 h of treatment where the HESM was also sterilized with ethanol to deplete bacterial factors. HESM supplement caused weight gain in 2 experiments and decreased blood corticosterone concentrations. While LPS caused a significant loss in body weight at 24 h following its administration, the HESM supplemented birds showed significantly less body weight loss compared with the control fed birds. The WBC, heterophil/lymphocyte ratio, and the levels of IgG were low in chickens fed diets with HESM supplement compared with control diet group. LPS challenge increased the expression of pro-inflammatory cytokine gene IL-6 but the HESM fed birds showed its effect curtailed, also, which also, favored the up-regulation of anti-inflammatory genes compared with control diet fed chickens. Post hatch supplementation of HESM appears to improve performance, modulate immunity, and increase

    Full Text Available Raw hatchery waste was cooked with water at 2:1 ratio for 15 minutes and then oven dried at 65C and ground. Hatchery waste meal (HWM thus prepared contained 32% crude protein, 16% ether extract, 0.9% crude fibre, 40% total ash, 11.1% nitrogen free extract, 20% calcium and 0.6 % available phosphorous with no E.Coli and Salmonella. In biological evaluation trail, non significant differences was observed among rations in which HWM replaced the fish meal at 0(A, 25(B, 50(C and 75 (D levels in broiler rations. These rations showed that protein efficiency ratios were 1.68, 1.79, 1.65,and 1.64 apparent biological value 59.96, 60.25, 59.75 and 58.32% respectively, indicating better balance of amino acid in HWM to be replaced with fish meal,. In 6 weeks performance trail, the body weight gains were 1807.69, 1916.39, 1788.39 and 1635.66 gm in A, B, C and D rations, respectively. Whereas, FCR values were 2.59, 2.32, 2.43 and 2.63 in the corresponding groups, which shows no significant difference among all rations. The cost per chick to market age was lowest in ration containing high level of HWM (7.5% and highest in ration containing high level of fish meal (10% indicating maximum replacement of fish meal by HWM in broiler ration is economical. Similarly, slaughtering data revealed no significant difference among all rations in all parameters. It may be concluded that the HWM can completely replace fish meal in commercial broiler rations.

    2012-04-01

    Full Text Available After President Lula’s two terms of office, the election of Dilma Rousseff generated all kinds of different expectations, whether because of the candidate’s lack of a political career within the Workers’ Party (PT, or because of her rather uncharismatic personality and poor propensity towards political negotiations with the allied parties that favoured the governability of the previous term of office. The country she has inherited is in a much better situation than the one inherited by the first PT government, with a stabilised economy and inflation under control. The sustainable policies for reducing poverty have generated conditions that encourage the enlargement of the middle class which, together with the creation of popular credit mechanisms, have served to halt the effects of the world crisis and have generated enormous expectations of social mobility. This scenario, together with the country’s increasingly recognised presence as an important international actor, provides unprecedented possibilities for the advancement of the “development with social inclusion” project. Nevertheless, certain reforms still need to be implemented that could threaten governability: political reform, federative agreement and tax reform, as well as social reforms.

    Many hatchery programs for steelhead pose genetic or ecological risks to natural populations because those programs release or outplant fish from non-native stocks. The goal of many steelhead programs has been to simply provide 'fishing opportunities' with little consideration given to conservation concerns. For example, the Washington Department of Fish and Wildlife (WDFW) has widely propagated and outplanted one stock of winter-run steelhead (Chambers Creek stock) and one stock of summer-run steelhead (Skamania stock) throughout western Washington. Biologists and managers now recognize potential negative effects can occur when non-native hatchery fish interact biologically with native populations. Not only do non-native stocks pose genetic and ecological risks to naturally spawning populations, but non-native fish stray as returning adults at a much higher rate than do native fish (Quinn 1993). Biologists and managers also recognize the need to (a) maintain the genetic resources associated with naturally spawning populations and (b) restore or recover natural populations wherever possible. As a consequence, the U.S. Fish & Wildlife Service (USFWS) and the NOAA Fisheries have been recommending a general policy that discourages the use of non-native hatchery stocks and encourages development of native broodstocks. There are two primary motivations for these recommendations: (1) reduce or minimize potential negative biological effects resulting from genetic or ecological interactions between hatchery-origin and native-origin fish and (2) use native broodstocks as genetic repositories to potentially assist with recovery of naturally spawning populations. A major motivation for the captive-rearing work described in this report resulted from NOAA's 1998 Biological Opinion on Artificial Propagation in the Columbia River Basin. In that biological opinion (BO), NOAA concluded that non-native hatchery stocks of steelhead jeopardize the continued existence of

    Full Text Available Rorty should be read as a reformer, rather than a revolutionary transformer. While the reformer aims to improve what is already good, the revolutionary transformer seeks to dispense with the merely good in a quest for the absolutely best. For Rorty this choice was a bad choice. In order to make the case that Rorty was a reformer,we explicate Rorty’s views on truth. These views argue that we can obtain consensus about what is worth preserving and improving without reference to either rightness, truth, or objectivity. For after all, there is no way for philosophers to get outside the circle of language within which we debate about what we take to be authoritative and aceptable.

    This report summarizes the results of the Lower Snake River Compensation Plan Hatchery Evaluation Studies (LSRCP) and the Imnaha Smolt Monitoring Program (SMP) for the 1999 smolt migration from the Imnaha River, Oregon. These studies were designed and closely coordinated to provide information about juvenile natural and hatchery chinook salmon (Oncorhynchus tshawytscha) and steelhead (Oncorhynchus mykiss) biological characteristics, behavior and emigrant timing, survival, arrival timing and travel time to the Snake River dams and McNary Dam on the Columbia River. Data collected from these studies are shared with the Fish Passage Center (FPC). These data are essential to quantify smolt survival rates under the current passage conditions and to evaluate the future recovery strategies that seek to optimize smolt survival through the hydroelectric system. Information shared with the FPC assists with in-season shaping of flow and spill management requests in the Snake River reservoirs. The Bonneville Power Administration and the United States Fish and Wildlife Service contracted the Nez Perce Tribe (NPT) to monitor emigration timing and tag 21,200 emigrating natural and hatchery chinook salmon and steelhead smolts from the Imnaha River during the spring emigration period (March 1-June 15) with passive integrated transponder (PIT) tags. The completion of trapping in the spring of 1999 marked the eighth year of emigration studies on the Imnaha River and the sixth year of participating in the FPC smolt monitoring program. Monitoring and evaluation objectives were to: (1) Determine spring emigration timing of chinook salmon and steelhead smolts collected at the Imnaha River trap. (2) Evaluate effects of flow, temperature and other environmental factors on emigration timing. (3) Monitor the daily catch and biological characteristics of juvenile chinook salmon and steelhead smolts collected at the Imnaha River screw trap.

    Study on the microscopic composition of biofloc in closed hatchery culture system was carried out to determine the interaction between the aggregation flocs in the bioremediation process for the decomposition and degradation of organic matter loaded in the shrimp culture tanks. The study was done for 105 days of culture period in zero water exchange. All of the organic loaded in the culture tanks identified comes from the shrimp feces, uneaten fed, and the decomposed macro- and microorganisms died in the culture tanks. All of the microscopic organisms in the biofloc were identified using Advance microscopes Nikon 80i. From the present study, there were abundances and high varieties of phytoplankton, zooplankton, protozoa, nematodes and algae species identified as aggregates together in the flocs accumulation. All of these microscopic organisms identified implemented the symbiotic process together for food supply, become the algae grazer, act as natural water stabilizer in regulating the nutrients in culture tank and serve as decomposer for dead organic matter in the water environment. Heterotrophic bacteria identified from Pseudomonas and Aeromonas family consumed the organic matter loaded at the bottom of culture tank and converted items through chemical process as useful protein food to be consumed back by the shrimp. Overall it can be concluded that the biofloc organisms identified really contributed as natural bioremediation agents in zero water exchange culture system to ensure the water quality in the optimal condition until the end of culture period.

  11. Estimate of resources required for a meaningful reform of education

    CERN Document Server

    Glazek, Stanislaw D

    2012-01-01

    A simple estimate in terms of currency units shows that a meaningful educational reform process can be launched and sustained over many generations of teachers with support of parents of students. In the estimate, the steady inflow of resources from parents provides support for advanced studies by teachers. Not to waste the resources on spurious activities, the estimated inflow proceeds directly from the parents as clients to the providers of required reform program. The providers are the experts in various disciplines who excel in helping teachers become great. Their services to teachers are ultimately assessed by parents on the basis of changes in behavior of children. The resulting reform program grows slowly from small seeds. The running cost of the reform process to parents appears surprisingly low while its development leads to the desired changes over time.

  12. The moral economy of austerity: analysing UK welfare reform.

    2016-03-01

    This paper notes the contemporary emergence of 'morality' in both sociological argument and political rhetoric, and analyses its significance in relation to ongoing UK welfare reforms. It revisits the idea of 'moral economy' and identifies two strands in its contemporary application; that all economies depend on an internal moral schema, and that some external moral evaluation is desirable. UK welfare reform is analysed as an example of the former, with reference to three distinct orientations advanced in the work of Freeden (1996), Laclau (2014), and Lockwood (1996). In this light, the paper then considers challenges to the reform agenda, drawn from third sector and other public sources. It outlines the forms of argument present in these challenges, based respectively on rationality, legality, and morality, which together provide a basis for evaluation of the welfare reforms and for an alternative 'moral economy'.

    1988-02-03

    The main functions of the National Marine Fisheries Service (NMFS) Aquaculture Task biologists and contractual scientists involved in the 1978 homing studies were primarily a surveillance of fish physiology, disease, and relative survival during culture in marine net-pens, to determine if there were any unusual factors that might affect imprinting and homing behavior. The studies were conducted with little background knowledge of the implications of disease and physiology on imprinting and homing in salmonids. The health status of the stocks was quite variable as could be expected. The Dworshak and Wells Hatcheries steelhead suffered from some early stresses in seawater, probably osmoregulatory. The incidences of latent BKD in the Wells and Chelan Hatcheries steelhead and Kooskia Hatchery spring chinook salmon were extremely high, and how these will affect survival in the ocean is not known. Gill enzyme activity in the Dworshak and Chelan Hatcheries steelhead at release was low. Of the steelhead, survival in the Tucannon Hatchery stock will probably be the highest, with Dworshak Hatchery stock the lowest. This report contains five previously published papers.

    2003-01-01

    In the Yakima Spring Chinook supplementation program, wild fish are brought into the Cle Elum Hatchery, artificially crossed, reared, transferred to acclimation sites, and released into the upper Yakima River as smolts. When these fish mature and return to the Yakima River most of them will be allowed to spawn naturally; a few, however, will be brought back to the hatchery and used for research purposes. In order for this supplementation approach to be successful, hatchery-origin fish must be able to spawn and produce offspring under natural conditions. Recent investigations on salmonid fishes have indicated that exposure to hatchery environments during juvenile life may cause significant behavioral, physiological, and morphological changes in adult fish. These changes appear to reduce the reproductive competence of hatchery fish. In general, males are more affected than females; species with prolonged freshwater rearing periods are more strongly impacted than those with shorter rearing periods; and stocks that have been exposed to artificial culture for multiple generations are more impaired than those with a relatively short exposure history to hatchery conditions.

  15. Source-sink estimates of genetic introgression show influence of hatchery strays on wild chum salmon populations in Prince William Sound, Alaska.

    Directory of Open Access Journals (Sweden)

    James R Jasper

    Full Text Available The extent to which stray, hatchery-reared salmon affect wild populations is much debated. Although experiments show that artificial breeding and culture influence the genetics of hatchery salmon, little is known about the interaction between hatchery and wild salmon in a natural setting. Here, we estimated historical and contemporary genetic population structures of chum salmon (Oncorhynchus keta in Prince William Sound (PWS, Alaska, with 135 single nucleotide polymorphism (SNP markers. Historical population structure was inferred from the analysis of DNA from fish scales, which had been archived since the late 1960's for several populations in PWS. Parallel analyses with microsatellites and a test based on Hardy-Weinberg proportions showed that about 50% of the fish-scale DNA was cross-contaminated with DNA from other fish. These samples were removed from the analysis. We used a novel application of the classical source-sink model to compare SNP allele frequencies in these archived fish-scales (1964-1982 with frequencies in contemporary samples (2008-2010 and found a temporal shift toward hatchery allele frequencies in some wild populations. Other populations showed markedly less introgression, despite moderate amounts of hatchery straying. The extent of introgression may reflect similarities in spawning time and life-history traits between hatchery and wild fish, or the degree that hybrids return to a natal spawning area. The source-sink model is a powerful means of detecting low levels of introgression over several generations.

  8. The 'reformation' of counselling

    G.A. Lotter

    2001-08-01

    Full Text Available Although the Reformation took place some four hundred years ago, one area in which reformation is really needed today is the counselling of people. Since Wilhelm Wundt started the “study of the mind” in 1879, William James and Sigmund Freud followed and secular psychology gradually has developed to take the “front seat”; hence moving Biblical counselling, which has been practised since the times of the New Testament, to the “back burner”. This development had been going on for the greater part of the 20th century, up to the publication of Competent to Counsel by Jay E. Adams in 1970. In the model for counselling suggested by Adams, the principles of the Reformation of the sixteenth century, Soli Deo Gloria, Soli Scriptura, Soli Fidei, Sola Gratia, etc. were again implemented in assisting and counselling people with personal and interpersonal problems. The epistomological and anthropological approach of secular psychology differs radically from that of Biblical principles, thus necessitating a new “reformation” of counselling. Within this new form counselling, inter alia, implies the following: the Word of God has its rightful place, sin has to be taken seriously and the work of the Holy Spirit should be recognised. In this article it is proposed that the “reformation” of counselling was started by scholars with a Biblical Reformational approach and that this method of counselling followed the parameters of the Reformation of the sixteenth century. This “reformation” developed into a new direction in counselling and still continues today with fascinating new frontiers opening up for Biblical counselling.

    Ten microsatellite markers were used to analyze the levels of genetic diversity and inbreeding in a hatchery release population of Rhopilema esculentum Kishinouye (Scyphozoa: Rhizostomatidae). A total of 85 alleles were detected in 600 individuals. Within-population levels of observed (H o) and expected (H e) heterozygosity ranged from 0.152 to 0.839 (mean=0.464) and from 0.235 to 0.821 (mean=0.618), respectively. The polymorphism information content (PIC) of each marker ranged from 0.207 to 0.795 with an average of 0.580, indicating that the hatchery population maintained a high level of genetic diversity. Inbreeding levels were estimated in the hatchery population and the inbreeding coefficient was 0.203. This result revealed that a certain level of inbreeding occurred within the population. Meanwhile, we also determined genetic diversity at the clone level. Several polyps from the same scyphistomae were genotyped at the ten microsatellite loci and there was virtually no difference in their genotypes. Furthermore, we calculated the probabilities of exclusion. When both parents were known, the average exclusion probability of ten loci was 99.99%. Our data suggest that the ten microsatellite markers can not only be used to analyze the identity of individuals but they can also be applied to parentage identification. Our research provides a theoretical basis and technical support for genetic diversity detection and reasonable selection of R. esculentum hatchery populations. These findings support the use of releasing studies and conservation of R. esculentum germplasm resources.

    To reveal the accumulation profile of tetrodotoxin (TTX) in pufferfish Takifugu rubripes juveniles, we compared the localization of TTX in various tissues among wild juveniles and hatchery-reared juveniles with or without TTX administration using immunohistochemical technique with anti-TTX monoclonal antibody. Immuno-positive reaction was observed in hepatic tissue, basal cell of skin and olfactory, olfactory epithelium, optic nerve and brain (optic tectum, cerebellum, medulla oblongata) of wild juveniles (body length: BL, 4.7-9.4 cm). TTX was detected in the same tissues as wild juveniles and epithelial cell layer of intestine of hatchery-reared juveniles (BL, 5.0-5.3 cm) to which TTX was orally administrated. No positive reaction was observed from the tissues of hatchery-reared juveniles without TTX administration. These results suggest that orally administrated TTX to the non-toxic cultured juveniles is accumulated in the same manner of wild juveniles. In addition, our study revealed that pufferfish accumulates TTX in the central nervous system.

    The kokanee Oncorhynchus nerka rehabilitation program for Lake Pend Oreille continued to show progress during 1989. Estimated kokanee abundance in late August was 7.71 million fish. Decreased population size is the result of lower hatchery and wild fry recruitment and low age 1+ survival. Lower recruitment of wild fry in 1989 resulted from a smaller parental escapement in 1988 and lower wild fry survival. Six fry release strategies were evaluated in 1989. Two groups were released in Clark Fork River to help improve a spawning run to Cabinet Gorge Hatchery. Survival from the mid-summer release, which was barged down Clark Fork River to avoid low flow problems, was not significantly different from the early release. The final assessment of these release strategies will be evaluated when adults return to Cabinet gorge Hatchery in 1992 and 1993. Fry released to support the Sullivan Springs Creek spawning run also survived will in 1989. Two open-water releases were made during early and mid-summer. 30 refs., 26 figs., 2 tabs.

    Decades of atmospheric acid deposition have resulted in widespread lake and river acidification in the northeastern U.S. Biological effects of acidification include increased mortality of sensitive aquatic species such as the endangered Atlantic salmon (Salmo salar). The purpose of this paper is to describe the development of a limestone-based fluidized bed system for the treatment of acid-impacted waters. The treatment system was tested at the Craig Brook National Fish Hatchery in East Orland, Maine over a period of 3 years. The product water from the treatment system was diluted with hatchery water to prepare water supplies with three different levels of alkalinity for testing of fish health and survival. Based on positive results from a prototype system used in the first year of the study, a larger demonstration system was used in the second and third years with the objective of decreasing operating costs. Carbon dioxide was used to accelerate limestone dissolution, and was the major factor in system performance, as evidenced by the model result: Alk = 72.84 ?? P(CO2)1/2; R2 = 0.975. No significant acidic incursions were noted for the control water over the course of the study. Had these incursions occurred, survivability in the untreated water would likely have been much more severely impacted. Treated water consistently provided elevated alkalinity and pH above that of the hatchery source water. ?? 2005 Elsevier B.V. All rights reserved.

    A growing body of literature suggests that adult salmon produced by artificial culture are not as reproductively successful as wild fish when they spawn under natural conditions. Behavioral, morphological, and physiological divergences have been observed between hatchery and wild fish. These disparities are the likely proximate causes of the differences seen in the reproductive success of hatchery and wild salmonids. Two evolutionary paradigms have been proposed to explain why salmonids cultured in hatcheries are genetically and phenotypically different from wild cohorts. The first proposes that natural selection has been significantly relaxed in hatcheries. Consequently, fish that normally would have perished because of the possession of unsuitable traits are able to survive. If these traits have a genetic basis, they may become established in a hatchery population and cause its productivity to be less than expected if the fish are once again exposed to natural selection pressures. The second theorizes that environmental and social conditions in hatcheries are less variable than in the natural environment and that these conditions will remain relatively constant from one generation to the next. In this circumstance, selection for genetic traits that adapt fish to artificial culture will become prevalent in the population. Such traits may be mal-adaptive under natural conditions. Many of the studies that have compared the reproductive success (RS) of hatchery and wild fish, however, have used non-local hatchery fish that have experienced multiple generations of hatchery culture. Few efforts have been made where both the hatchery and wild fish have originated from the same population. When such studies have been performed differences in the competency of the fish to produce offspring have not been detected or are not as great as those expressed when non-local hatchery fish have been used.

    In this article,antibiogram and heavy metal resistance profile of bacteria isolated from giant freshwater prawn (Macrobrachium rosenbergii) hatchery in Malaysia are described.Although giant freshwater prawn was introduced into Malaysia since the 1980s,there was no database information on antibiogram and heavy metal resistance profile of bacteria from giant freshwater prawn (M.rosenbergii) hatchery in Malaysia.Therefore,this study was carried out to determine the effectiveness of antibiotic and heavy metal resistance profile to control bacterial diseases in M.rosenbergii hatchery.The results can provide valuable information for local M.rosenbergii post-larval producer.Antibiotic sensitivity test was carried out by disk-diffusion method against 15 types of antibiotics as follows:oxolinic acid (2 μg),ampicillin (10 μg),erythromycin (15 μg),furazolidone (15 μg),lincomycin (15 μg),amoxicillin (25 μg),col istin sulphate (25 μg),doxycycline (30 μg),florfenicol (30 μg),flumequine (30 μg),nalidixic acid (30 μg),tetracycline (30 μg),oleandomyein (15 μg),fosfomycin (50 μg),and spiramycin (100 μg),whereas heavy metal resistance profile of the present bacterial isolates was determined by 2-fold agar dilution technique.In this study,5 types of bacteria were successfully isolated;they were Aeromonas spp.(n= 77),Escherichia coil (n = 73),Edwardsiella spp.(n = 62),Salmonella spp.(n= 75),and Vibrio spp.(n = 43).The result showed that furazolidone was the most effective antibiotic to control the bacteria isolated in this study,approximately 89.7% of the bacterial isolates were sensitive to this antibiotic.Multiple antibiotic resistance (MAR) index indicated that the hatchery water source and M.rosenbergii post-larval and sediment tanks were at high-risk exposure to the tested antibiotic.Furthermore,all the tested heavy metals (Cd2+,Cr6+ Hg2+,and Cu2+) failed to inhibit the growth of the bacterial isolates.Therefore,it indicated that the water source of the hatchery is

    There is a considerable interest in using hatcheries to speed the recovery of wild populations. The Bonneville Power Administration (BPA), under the authority of the Northwest Power Planning Act, is currently funding several hatchery programs in the Columbia Basin as off-site mitigation for impacts to salmon and steelhead caused by the Columbia River federal hydropower system. One such project is located on the Hood River, an Oregon tributary of the Columbia. These hatchery programs cost the region millions of dollars. However, whether such programs actually improve the status of wild fish remains untested. The goal of this project was to evaluate the effectiveness of the Hood River hatchery program as required by the Northwest Power Planning Council Fish and Wildlife Program, by the Oregon Plan for Coastal Salmonids, by NMFS ESA Section 4(d) rulings, and by the Oregon Department of Fish and Wildlife (ODFW) Wild Fish Management Policy (OAR 635-07-525 through 529) and the ODFW Hatchery Fish Gene Resource Management Policy (OAR 635-07-540 through 541). The Hood River supports two populations of steelhead, a summer run and a winter run. They spawn only above the Powerdale Dam, which is a complete barrier to all salmonids. Since 1991 every adult passed above the dam has been measured, cataloged and sampled for scales. Therefore, we have a DNA sample from every adult steelhead that went over the dam to potentially spawn in the Hood River from 1991 to the present. Similar numbers of hatchery and wild fish have been passed above the dam during the last decade. During the 1990's 'old' domesticated hatchery stocks of each run (multiple generations in the hatchery, out-of-basin origin; hereafter H{sub old}) were phased out, and conservation hatchery programs were started for the purpose of supplementing the two wild populations (hereafter 'new' hatchery stocks, H{sub new}). These samples gave us the unprecedented ability to estimate, via

    Full Text Available Hatchery-bred early juvenile Milkfish (Chanos chanos Forsskål, 1755 (average weight of 0.45g were stocked in a 500 m2 nursery pond at a density of 16 juveniles/m2 during the dry months (March-May. The early juveniles were reared for two months with natural food followed by supplementalfeeding. Upon the harvest the fish reached an average weight of 9.30 g and a survival rate of 86.9%. Afeed conversion ratio (FCR of 1.08 was attained, with specific growth rate (SGR of 4.96%/day. Thehigh survival rate and good production could be attributed to the time of the year when the nurseryproduction trial was conducted. The nursery of milkfish in ponds during the summer months ensuressufficient supply of natural food and stable water quality during the crucial phase in the nurseryproduction. This strategy of rearing early juveniles (< 1g of milkfish in nursery ponds at high stockingdensities using a combination of natural food and supplemental feeding could be one of the alternativeapproaches in the nursery production of this fish.

    A partial oxidation reformer comprising a longitudinally extending chamber having a methanol, water and an air inlet and an outlet. An igniter mechanism is near the inlets for igniting a mixture of methanol and air, while a partial oxidation catalyst in the chamber is spaced from the inlets and converts methanol and oxygen to carbon dioxide and hydrogen. Controlling the oxygen to methanol mole ratio provides continuous slightly exothermic partial oxidation reactions of methanol and air producing hydrogen gas. The liquid is preferably injected in droplets having diameters less than 100 micrometers. The reformer is useful in a propulsion system for a vehicle which supplies a hydrogen-containing gas to the negative electrode of a fuel cell.

    Many hatchery programs for steelhead pose genetic or ecological risks to natural populations because those programs release or outplant fish from non-native stocks. The goal of many steelhead programs has been to simply provide 'fishing opportunities' with little consideration given to conservation concerns. For example, the Washington Department of Fish and Wildlife (WDFW) has widely propagated and outplanted one stock of winter-run steelhead (Chambers Creek stock) and one stock of summer-run steelhead (Skamania stock) throughout western Washington. Biologists and managers now recognize potential negative effects can occur when non-native hatchery fish interact biologically with native populations. Not only do non-native stocks pose genetic and ecological risks to naturally spawning populations, but non-native fish stray as returning adults at a much higher rate than do native fish (Quinn 1993). Biologists and managers also recognize the need to (a) maintain the genetic resources associated with naturally spawning populations and (b) restore or recover natural populations wherever possible. As a consequence, the U.S. Fish & Wildlife Service (USFWS) and the NOAA Fisheries have been recommending a general policy that discourages the use of non-native hatchery stocks and encourages development of native broodstocks. There are two primary motivations for these recommendations: (1) reduce or minimize potential negative biological effects resulting from genetic or ecological interactions between hatchery-origin and native-origin fish and (2) use native broodstocks as genetic repositories to potentially assist with recovery of naturally spawning populations. A major motivation for the captive-rearing work described in this report resulted from NOAA's 1998 Biological Opinion on Artificial Propagation in the Columbia River Basin. In that biological opinion (BO), NOAA concluded that non-native hatchery stocks of steelhead jeopardize the continued existence of

    A total of 350,000, M012 strain, westslope cutthroat trout (WCT) eggs were received from Montana Fish Wildlife & Parks (MFWP), Washoe Park State Fish Hatchery in June of 2005 to accomplish this fishery management objective. These eggs were incubated, hatched and reared entirely inside the hatchery nursery building using a protected well water supply. Fish grew according to schedule and survival was excellent. The hatchery achieved a 0.78 feed fed to pounds gained conversion ratio for this group of WCT. Not all of the progenies from this fish lot were used for Hungry Horse Dam Fishery Mitigation Implementation. Some were used for other regional fishery management projects. Westslope cutthroat trout were reared using approved fish culture techniques as recommended in the USFWS Fish Hatchery Management Handbook and also utilizing a regimen adapted for hatchery specific site conditions. The fish health for these WCT was very good. Survival from first feeding fry stage to stocking was 79%. The hatchery had an annual fish health inspection performed by the USFWS Bozeman Fish Health Center in mid March of 2006. This inspection found all fish lots at Creston to be disease free. The Montana State Fish Health Board has placed the hatchery under a limited quarantine since May of 2005 due to an epizootic of Furunculosis. This classification has allowed the Creston NFH to stock disease free fish in locations approved by regional fish managers. The hatchery has been working with the State Fish Pathologist to remove the limited quarantine classification from the facility. Although fish health for all station fish lots remains disease free, MFWP has asserted it will not remove the limited quarantine until the new influent water treatment system, including the ultraviolet disinfection unit, is running full time, year round. The USFWS is working to secure the additional funding necessary to operate the treatment building year round. Distribution of the WCT took place from March

  7. The Finish Municipal Reform

    Full Text Available The article aims at evaluating the municipal amalgamation process as a way of reforming local government, by two criteria – efficiency in service provision and level of democracy. Those issues are applied onto a Finnish case study, as amalgamation is more common in Northern Europe. The author gives a review of amalgamation studies in the world and of the extensive evaluation reports of amalgamation reform in Finland. The paper examines amalgamation policy from two perspectives – from the instrumental or goal-oriented view and from the process aspect. The findings on the relatively high number of instances of amalgamation in Finland are the following: the main process-driving factors were political parties that mostly supported the reform and the underlying urge to construct larger entities which made municipalities take part in the process. The level of efficiency in the New, amalgamated municipalities is not necessarily higher, as efficient service provision can be found both in small and large municipalities. Efficiency is more determined by the dynamics of a municipal economy while the size of a municipality alone does not make a difference. As amalgamations change the nature of local political life they affect democracy both positively and negatively.

    This study was initiated in the early 1990s to provide managers with data comparing genetic fitness for natural rearing, as measured by survival of juveniles in freshwater, between steelhead Oncorhynchus mykiss from Dworshak National Fish Hatchery and wild steelhead from the Clearwater River, Idaho. We artificially spawned hatchery steelhead and wild steelhead from the Selway River, a Clearwater River tributary, released the resulting genetically marked (at the PEPA allozyme locus) progeny (HxH, HxW from hatchery females and wild males, and WxW) as unfed fry in a second order tributary of the South Fork Clearwater River, and monitored fish residing in the stream or emigrating from it for five years. Barrier falls prevented access to the stream by naturally produced steelhead. Over 90% of the emigrants were one or two years of age and too small to be smolts (mean fork length at age-2 = 103 mm). Per fry released, the HxH cross produced 0.64-0.83 times as many emigrants as the WxW cross (PWxW cross for one year-class (P=0.051) and 0.68 times as many for the other (ns). Survival from age-1 to age-4 was lower for HxH than for WxW residuals of one year-class (PWxW residuals of the other (P=0.062). Collectively, these results indicate lower survival for HxH than for WxW fish. Size was often greater for HxH than for WxW fish indicating faster growth for the former, and condition factor was also usually greater for HxH than for WxW fish. Dispersal of fry from release sites and emigration of one- and two-year olds from the study stream were greater for WxW than for HxH fish, and apparently neither was from competitive displacement of small by larger fish. Incidence of flowing milt was higher for HxH than for WxW fish at age-2. Peak incidence of flowing milt for older residuals was similar among crosses (about 50%), but the peak occurred at greater size and age for WxW than for HxH residuals. HxW fish were intermediate between HxH and WxW fish, not similar to HxH fish, in

    2005-01-01

    The population of endangered razorback suckers Xyrauchen texanus in the middle Green River (upper Colorado River basin) has declined during the last 40 years. The apparent cause for this decline is a lack of successful recruitment. This study used radiotelemetry to evaluate the ability of hatchery-reared razorback suckers to locate spawning areas where wild fish congregate during the ascending hydrographic limb of the snowmelt runoff. Hatchery-reared razorback suckers appeared to show similar reproductive behavior to wild fish. Both wild and hatchery-reared fish were found near the middle Green River spawning area between 1 and 25 May 2000. Hatchery fish occupied the same areas on the spawning site as wild fish, and remained on the spawning site during both nocturnal and diurnal hours. Males were more abundant on the spawning area than females, but the few females captured tended to stage away from the primary spawning area. The results from this study suggest hatchery-reared fish are capable of responding to natural cues that prompt spawning aggregations and are successful in locating existing spawning aggregations of wild fish. Given attention to stocking criteria, including genetic diversity and the size and time of stocking, the challenges of recovering razorback suckers will center on those factors that led to the population declines, particularly the survival of early life stages in off-channel habitats. ??

    Radio and acoustic telemetry were used to monitor the seasonal movement of hatchery-reared and wild shortnose sturgeon (622-927 mm total length) in the Savannah River. Diploid, and sterile hatchery-reared shortnose sturgeon, and wild shortnose sturgeon showed apparent similar seasonal patterns of movement within the river. We were unable to detect any significant differences in the seasonal mean river location, minimum daily distance moved, absolute distance moved, displacement or mean territory size among treatments. Fish moved throughout the brackish and freshwater interface area of the Savannah River during the summer months. Coinciding with decreasing fall temperatures, fish of all treatment groups moved downriver into brackish areas of the upper estuary, residing in the Front, Middle, and Back Rivers, where they remained through winter. Upriver movements of some hatchery-reared and wild groups began in early February as river temperatures began to increase. Shortnose sturgeon from each group selected apparent similar thermal, salinity and water depth conditions throughout the year. Hatchery-reared fish may be useful as surrogates for wild fish in behavioural studies. Triploid or surgically-sterilized fish may be used in situ behavioural studies where genetic contamination is a concern. It may be possible to monitor habitats used by released hatchery-reared fish to locate or verify remnant populations of rare or endangered species in systems where they are thought to be extirpated.

    Numbers of Snake River sockeye salmon Oncorhynchus nerka have declined dramatically in recent years. In Idaho, only the lakes of the upper Salmon River (Sawtooth Valley) remain as potential sources of production (Figure 1). Historically, five Sawtooth Valley lakes (Redfish, Alturas, Pettit, Stanley, and Yellowbelly) supported sockeye salmon (Bjornn et al. 1968; Chapman et al. 1990). Currently, only Redfish Lake receives a remnant anadromous run. On April 2, 1990, the National Oceanic and Atmospheric Administration Fisheries Service (NOAA - formerly National Marine Fisheries Service) received a petition from the Shoshone-Bannock Tribes (SBT) to list Snake River sockeye salmon as endangered under the United States Endangered Species Act (ESA) of 1973. On November 20, 1991, NOAA declared Snake River sockeye salmon endangered. In 1991, the SBT, along with the Idaho Department of Fish & Game (IDFG), initiated the Snake River Sockeye Salmon Sawtooth Valley Project (Sawtooth Valley Project) with funding from the Bonneville Power Administration (BPA). The goal of this program is to conserve genetic resources and to rebuild Snake River sockeye salmon populations in Idaho. Coordination of this effort is carried out under the guidance of the Stanley Basin Sockeye Technical Oversight Committee (SBSTOC), a team of biologists representing the agencies involved in the recovery and management of Snake River sockeye salmon. National Oceanic and Atmospheric Administration Fisheries Service ESA Permit Nos. 1120, 1124, and 1481 authorize IDFG to conduct scientific research on listed Snake River sockeye salmon.

    1991-01-01

    Initially, rehabilitation of kokanee Oncorhynchus nerka met with apparent success reaching a peak abundance of 10.2 million fishTl988. However, a decline of 47% followed from 1988 through 1991 to 5.4 million fish. The decreased population was attributed to poor recruitment of wild fish, poor egg take, thus, low stocking of hatchery fry (7.3 million in 1990 and 5.0 million in 1991 compared to about 13.0 million in 1981), and poor survival of fish ages 3 and 4 (average survival of the older fish was only 35% in 1990 compared to 72% in prior years but it was 68% in 1991). In addition, standing stocks of kokanee have remained relatively stable (x = 8.6 kg/hectare) since 1986 despite the dramatic changes in density. Prior to this study (1985) standing stocks were substantially higher (x = 13.6 kg/hectare). The kokanee population is probably operating below carrying capacity. Hatchery fry comprised 59% of the total kokanee recruitment in 1991 (93% of fry biomass). This contribution of 1.06 million fry ranked fifth behind 1988 (3.74 million), 1989 (2.25 million), 1982 (1.89 million), and 1990 (1.56 million) since hatchery supplementation began in the 1970s. Survival of hatchery fry was 21% in 1991, the second highest since this investigation began. Two release strategies were tested in 1991 of which the best survival was recorded for the Sullivan Springs release at 23% while the early Clark Fork River release continued to have lowest survival at 18%. Survival of hatchery reared kokanee fry is still below the goal of 30% and it appears that this goal may not be attainable most years. Statistical analysis between number of days from fry release to recapture day and fry survival did not reveal a relationship (P = 0.43). Survival of fry from late releases is higher (P = 0.05) than early releases but no difference (P L 0.71) was detected between stocking locations. Good survival of fry from the Sullivan Springs releases was attributed to large size of kokanee fry (55 mm), warm

    Two waste streams from a Leghorn hatchery were preserved and recycled by fermentation with a by-product carbohydrate and extrusion processing into new feed ingredients that were evaluated with broiler chickens. Cockerel chicks (CC) and a 60:40 ratio of CC:shell waste (CC:SW) were fermented in 189-L barrels for 21 d following grinding, then mixing with a liquid culture (0.2%) and carbohydrate source at 15 and 16.66%, respectively. At 2 wk, pH was 4.44 and 5.09 for the CC and CC:SW products compared with higher values of 6.54 and 6.98 for the raw ingredients at the onset. Negligible hydrogen sulfide and no ammonia gas were recorded during the fermentation period. At 21 d, the fermented CC and CC:SW were extruded, dried, and ground to meals containing CP and TMEn levels of 47.4%, 3,187 kcal/kg, and 33.1%, 2,696 kcal/kg, respectively. Broiler chickens were fed a control diet and the CC (5 and 10%) and CC:SW (2.5 and 5%) ingredient diets with corn and soybean meal for 6 wk to evaluate feeding value and carcass yield. Body weight, gain and feed conversion at 42 d for birds fed diets supplemented with CC or CC:SW at all levels were comparable to those of the control. Diets supplemented with hatchery by-product had no negative effect on carcass measurements except ready to cook carcass and wing yield, which were significantly greater for the 10% CC:SW birds than for the control. These data indicate that nutrient dense hatchery by-products can be preserved with fermentation up to 21 d and support broiler live performance and carcass yield as dietary ingredients equal to or better than a corn-soybean meal control.

    The National Marine Fisheries Service (NMFS), under contract to the Bonneville Power Administration, is conducting research on imprinting salmon and steelhead for homing (Slatick et al. 1979, 1980; Novotny and Zaugg 1979). The studies were begun with little background knowledge of the effects of disease or certain physiological functions on imprinting and homing in salmonids. Consequently, work aimed at filling this void was begun by the authors in 1978 (Novotny and Zaugg 1979) and continued in 1979. In 1979, we examined random samples of normal populations of homing test fish at the hatcheries to determine the physiological readiness to migrate and adapt to seawater and general fish health. At the Manchester Marine Experimental Station, Manchester, Washington, we determined the survival of samples of the test fish maintained in marine net-pens after release from the hatcheries. Hatcheries and stocks sampled are listed in Table 1.

    The goal of this report is to document current production practices for hatcheries which rear anadromous fish in the Columbia River Basin and to identify those facilities where production can be increased. A total of 85 hatchery and satellite facilities operated by the Idaho Department of Fish and Game, Oregon Department of Fish and Game, US Fish and Wildlife Service, Washington Department of Wildlife, and Washington Department of Fisheries were evaluated. The years 1985 to 1987 were used in this evaluation. During those years, releases averaged 143,306,596 smolts weighing 7,693,589 pounds. A total of 48 hatchery or satellite facilities were identified as having expansion capability. They were estimated to have the potential for increasing production by an 84,448,000 smolts weighting 4,853,306 pounds. 2 refs., 25 figs.

    Mitigation Objective 1: Produce Native Westslope Cutthroat Trout at Creston NFH--Task: Acquire eggs and rear up to 100,000 Westslope Cutthroat trout annually for offsite mitigation stocking. Accomplishments: A total of 141,000 westslope cutthroat eggs (M012 strain) was acquired from the State of Montana Washoe Park State Fish Hatchery in May 2002 for this objective. We also received an additional 22,000 westslope cutthroat eggs, MO12 strain naturalized, from feral fish at Rogers Lake, Flathead County, Montana. The fish were reared using approved fish culture techniques as defined in the U.S. Fish and Wildlife Service, Fish Hatchery Management guidelines. Survival from the swim up fry stage to stocking was 95.6%. We achieved a 0.80 feed conversion this year on a new diet, Skretting ''Nutra Plus''. Post release survival and angler success is monitored annually by Montana Fish Wildlife and Parks (MFWP) and the Confederated Salish and Kootenai Tribe (CSKT). Stocking numbers and locations vary yearly based on results of biological monitoring and adaptive management. Mitigation Objective 2: Produce Rainbow Trout at Creston NFH--Task: Acquire and rear up to 100,000 Rainbow trout annually for offsite mitigation in closed basin waters. Accomplishments: A total of 54,000 rainbow trout eggs (Arlee strain) was acquired from the Ennis National Fish Hatchery in December 2002 for this objective. The fish were reared using approved fish culture techniques as defined in the U.S. Fish and Wildlife Service, Fish Hatchery Management guidelines. Survival from the swim up fry stage to stocking was 99.9%. We achieved a 0.79 feed conversion this year on a new diet, Skretting ''Nutra Plus''. Arlee rainbow trout are being used for this objective because the stocking locations are terminal basin reservoirs and habitat conditions and returns to the creel are unsuitable for native cutthroat. Post release survival and angler success is monitored annually

    1996-12-31

    An environmental tax reform is seen by many as a possible solution to some crucial problems of modern society - pollution, excessive resource consumption and unemployment. Changes in the system of taxation are here seen as a long term process, one that must cheapen the costs of labour and make the costs of resource use more expensive - a process which can also create major changes in our society as to conceptions of quality, work, consumption etc. The conference presented proposals for an ecological tax and duty system that would contribute to: Changing technology so that it becomes more resource and energy effective. Changing the economic mechanisms so that resource consumption and pollution become more expensive while human resources become cheaper. Changing personal life styles and values so that material consumption becomes less decisive for our choices and priorities. An environmental tax reform is neither without problems nor painless. An economy and an industrial sector based on increasing consumption of energy and raw materials will, in the long run, lead to drawbacks that far outweigh those that are connected with an economic re-orientation whose driving force is another conception of nature.

  15. Small School Reform

    Full Text Available This qualitative ethnographic case study explored the evolution of a public urban high school in its 3rd year of small school reform. The study focused on how the high school proceeded from its initial concept, moving to a small school program, and emerging as a new small high school. Data collection included interviews, observations, and document review to develop a case study of one small high school sharing a multiplex building. The first key finding, “Too Many Pieces, Not Enough Glue,” revealed that the school had too many new programs starting at once and they lacked a clear understanding of their concept and vision for their new small school, training on the Montessori philosophies, teaching and learning in small schools, and how to operate within a teacher-cooperative model. The second key finding, “A Continuous Struggle,” revealed that the shared building space presented problems for teachers and students. District policies remain unchanged, resulting in staff and students resorting to activist approaches to get things done. These findings offer small school reform leaders suggestions for developing and sustaining a small school culture and cohesion despite the pressures to revert back to top-down, comprehensive high school norms.

  16. Power Tariff Reform and Energy Constraint in China

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    Power tariff reform and power restructuring should be coordinately advanced. In the period of the power tariff reform, attention should be fully given to possible demand growth, investment characteristics and environment pressure when taking transitional measures. In the stage, focal point of the reform is to establish a rational system of sales price to power network. Moreover, it is necessary to raise the electricity price for household consumption. The highly-centralized system of state-owned power enterprises is the root-cause of some basic problems in the power industry. The system would cause a great power overproduction, squeeze out private and foreign investment and constrain efficiency improvement. Effective energy strategy and planning are a crux of dealing with crises of energy security. China needs a state-class energy administration body and should make massive research on energy economics.

  17. Public Administration reforms and results

    Directory of Open Access Journals (Sweden)

    Gunnar Helgi Kristinsson

    2014-12-01

    Full Text Available Research on administrative reforms during the past thirty years indicates that reform efforts of countries differ. The Anglo Saxon states were at the forefront of the New Public Management movement while countries on mainland Europe were more hesitant and moved further towards the Neo-Weberian state. Academics have tried to explain different reform efforts within countries by looking at political, historical and cultural issues, values and economic factors to name just a few. Three hypotheses are put forward to explain reform efforts in different states. This research involves analysing the implementation of two different reform trends, New Public Management and the Neo-Weberian tradition. The analysis indicates that countries vary in their commitment to reform rather than in the emphasis on either New Public Management or the Neo-Weberian State. Decentralization, clear objectives and consultation with communities and experts are closely related to national reform efforts. However, Iceland does distinguish itself from Europe and the Nordic countries. The analysis reveals that although decentralization is high in the Icelandic system, autonomy of agencies does not have a strong relation to a varied use of administrative instruments. The second part of the article focuses on the results and achievements of reform programmes. The achievement of reform programmes are examined in relation to theories of bounded rationality, street level bureaucracy (bottom up and consensus decision making. Three hypotheses are presented and tested to explain what causes reforms programmes to be successful in some countries and not in others. The analysis reveals that countries are more likely to succeed if bounded rationality is applied with careful preparation and when stakeholders are consulted.

    Eleven Danish brown trout hatchery strains were studied by PCR- RFLP analysis of the ND-I and ND-5/6 segments of the mitochondrial genome. For comparison, data from wild trout representing three Danish river systems also were included. Reduced variability in terms of nucleon diversity and number...... of haplotypes was observed in most hatchery strains. However, computer simulations showed that even with relatively large numbers of female spawners considerable loss of haplotypes could take place over time. Therefore, reduced variability in some of the strains did not necessarily indicate a critical loss...

  19. Chile's health sector reform: lessons from four reform periods.

    Science.gov (United States)

    de la Jara, J J; Bossert, T

    1995-01-01

    This paper applies an interdisciplinary approach to analyze the process of health reform in four significant periods in Chilean history: (1) the consolidation of state responsibility for public health in the 1920s, (2) the creation of the state-run National Health Service in the 1950s, (3) the decentralization of primary care and privatization of health insurance in the 1980s, and (4) the strengthening of the mixed public-private market in the 1990s. Building on the authors' separate disciplines, the paper examines the epidemiological, political and economic contexts of these reforms to test simple hypotheses about how these factors shape reform adoption and implementation. The analysis underlines: (1) the importance of epidemiological data as an impetus to public policy; (2) the inhibiting role of economic recession in adoption and implementation of reforms: and (3) the importance of the congruence of reforms with underlying political ideology in civil society. The paper also tests several hypotheses about the reform processes themselves, exploring the role of antecedents, interest groups, and consensus-building in the policy process. It found that incremental processes building on antecedent trends characterize most reform efforts. However, interest group politics and consensus building were found to be complex processes that are not easily captured by the simple hypotheses that were tested. The interdisciplinary approach is found to be a promising form of analysis and suggests further theoretical and empirical issues to be explored.

  20. Public Benefits and Power Sector Reform. Report from an International Workshop

    Energy Technology Data Exchange (ETDEWEB)

    Nilsson, Lars J.; Arvidson, Anders; Eberhard, Anton (eds.)

    2003-10-01

    The Workshop on Public Benefits and Power Sector Reform was motivated by the need to address broader development goals and advance the provision of public benefits in power sector reforms. The primary objectives were: To provide a forum for a discussion among specialists, of how the provision of public benefits can be expanded as power sectors in developing countries are reformed, and review the experience (Day 1). To identify the needs for training and capacity building and institutional arrangements, as well as make recommendations for their design and implementation, for policy makers, regulators, and other professionals in developing countries (Day 2). Public benefits is a socially constructed concept that includes activities that are not adequately conceived by competitive markets. Public benefit policies and programmes include those that expand electricity access to rural areas and the urban poor, improve security of supply, promote energy efficiency and renewable energy, etc. Reforms have indeed been a threat to public benefits as traditionally delivered through electric utilities. However, in many cases public benefit programmes have also been rescued. In fewer cases, public benefit programmes have been conceived in the reform process. From experience so far it is clear that power sector reforms must be made more compatible with broader sustainable development goals. Recognising the need for broader policy integration and putting public benefits higher on the reform agenda points to the importance of reaching beyond energy ministries and power sector experts at an early stage in the reform process. Other actors, such as NGOs and academia, may also be instrumental in monitoring and assessing the impacts of reform. Public benefits can be an integral part of a reform package, or a complement to reform. It does appear that reform creates space and opportunity to achieve public benefits, but someone has to utilise that opportunity. The need to make trade

  1. Microsatellite DNA markers: evaluating their potential for estimating the proportion of hatchery-reared offspring in a stock enhancement programme.

    Bravington, M V; Ward, R D

    2004-05-01

    We describe a statistical method for estimating the effectiveness of a stock enhancement programme using nuclear DNA loci. It is based on knowing the population allele frequencies and the genotypes of the hatchery parents (mother only, or mother and father), and on determining the probability that a wild-born animal will by chance have a genotype consistent with hatchery origin. We show how to estimate the proportion of released animals in the wild population, and its standard error. The method is applied to a data set of eight microsatellite loci in brown tiger prawns (Penaeus esculentus), prior to the start of a possible enhancement programme. We conclude that, for this particular data set, the effectiveness of such an enhancement programme could be quantified accurately if both maternal and paternal genotypes are known, but not if maternal genotypes only are known. Full paternal genotyping would require offspring genotyping and thus would be expensive, but a partly typed paternal genotype from a mass homogenate of offspring would be almost as effective and much cheaper. The experiment would become feasible based on maternal genotypes alone, if a further three typical microsatellite loci could be found to add to the existing panel of eight. The methods detailed should be of interest to any enhancement project that relies on nuclear DNA markers to provide tags.

    1987-02-01

    Estimated kokanee (Oncorhynchus nerka) abundance in Lake Pend Oreille was 4.3 million during September 1986. This estimate was similar to 1985 and indicates continued suppression of the kokanee population since initial decline in the late 1960s. Atypically high survival of wild fry resulted in similar fry recruitment in 1986 as 1985, whereas hatchery-reared fry contributed only 8% to total fry recruitment as a result of low post-release survival (3%). Fry released into the Clark Fork River from Cabinet Gorge Hatchery had very low survival during emigration to Lake Pend Oreille, resulting from poor flow conditions and potentially high predation. Fry survival during emigration was twice as high during nighttime flows of 16,000 cfs than 7,800 cfs. Emigration also was faster during higher flows. Several marks were tested to differentially mark fry release groups to help determine impacts of flow and other factors on fry survival. Survival of fry marked with tetracycline and fluorescent dye was high (>99%) during the 10-week study. In contrast, survival of fry marked with fluorescent grit marks ranged from 5 to 93%, depending on application pressure and distance from the fry. Retention was high (>96%) for tetracycline and grit marks during the study, whereas dye marks were discernible (100%) for only one week. 23 refs., 20 figs., 10 tabs.

    The operation of the Federal Columbia River Power System (FCRPS) has negatively affected threatened and endangered salmonid populations in the Pacific Northwest. Barging Snake River spring Chinook salmon Oncorhynchus tshawytscha through the FCRPS is one effort to mitigate the effect of the hydrosystem on juvenile salmon out-migration. However, little is known about the occurrence and transmission of infectious agents in barged juvenile salmon relative to juvenile salmon that remain in-river to navigate to the ocean. We conducted a survey of hatchery-reared spring Chinook salmon at various points along their out-migration path as they left their natal hatcheries and either migrated in-river or were barged through the FCRPS. Salmon kidneys were screened by polymerase chain reaction for nine pathogens and one family of water molds. Eight pathogens were detected; the most prevalent were Renibacterium salmoninarum and infectious hematopoietic necrosis virus. Species in the family Saprolegniaceae were also commonly detected. Pathogen prevalence was significantly greater in fish that were barged through the FCRPS than in fish left to out-migrate in-river. These results suggest that the transmission of infectious agents to susceptible juvenile salmon occurs during the barging process. Therefore, management activities that reduce pathogen exposure during barging may increase the survival of juvenile Chinook salmon after they are released.

    2010-10-01

    Full Text Available Japanese scallop (Mizuhopecten yessoensis is a cold-tolerant bivalve that was introduced to China for aquaculture in 1982. In this study, amplified fragment length polymorphism (AFLP markers were used to investigate levels of genetic diversity within M. yessoensis cultured stocks and compare them with wild populations. Six pairs of primer combinations generated 368 loci among 332 individuals, in four cultured and three wild populations. High polymorphism at AFLP markers was found within both cultured and wild M. yessoensis populations. The percentage of polymorphic loci ranged from 61.04% to 72.08%, while the mean heterozygosity ranged from 0.2116 to 0.2596. Compared with wild populations, the four hatchery populations showed significant genetic changes, such as lower expected heterozygosity and percentage of polymorphic loci, and smaller frequency of private alleles, all indicative of a reduction in genetic diversity. Some genetic structures were associated with the geographical distribution of samples; with all samples from Dalian and Japan being closely related, while the population from Russia fell into a distinct clade in the phylogenetic analysis. The genetic information derived from this study indicated that intentional or accidental release of selected Japanese scallops into natural sea areas might result in disturbance of local gene pools and loss of genetic variability. We recommend monitoring the genetic variability of selected hatchery populations to enhance conservation of natural Japanese scallop resources.

    The Comparative Survival Rate Study (CSS) is a multi-year program of the fishery agencies and tribes to measure the smolt-to-adult survival rates of hatchery spring and summer chinook at major production hatcheries in the Snake River basin and at selected hatcheries in the lower Columbia River. The CSS also compares the smolt-to-adult survival rates for Snake River basin chinook that were transported versus those that migrated in-river to below Bonneville Dam. Estimates of smolt-to-adult survival rates will be made both from Lower Granite Dam back to Lower Granite Dam (upriver stocks) and from the hatchery back to the hatchery (upriver and downriver stocks). This status report covers the first three migration years, 1996 to 1998, of the study. Study fish were implanted with a PIT (Passive Integrated Transponder) tag which allows unique identification of individual fish. Beginning in 1997, a predetermined proportion of the PIT tagged study fish in the collection/bypass channel at the transportation sites, such as Lower Granite and Little Goose dams, was purposely routed to the raceways for transportation and the rest was routed back to the river. Two categories of in-river migrating fish are used in this study. The in-river group most representative of the non-tagged fish are fish that migrate past Lower Granite, Little Goose, and Lower Monumental dams undetected in the bypass systems. This is because all non-tagged fish collected at these three dams are currently being transported. The other in-river group contains those fish remaining in-river below Lower Monumental Dam that had previously been detected at one or more dams. The number of fish starting at Lower Granite dam that are destined to one of these two in-river groups must be estimated. The Jolly-Seber capture-recapture methodology was used for that purpose. Adult (including jacks) study fish returning to the hatcheries in the Snake River basin were sampled at the Lower Granite Dam adult trap. There the PIT

    Reference price systems for prescription drugs have found widespread use as cost containment tools. Under such regulatory regimes, patients co-pay a fraction of the difference between pharmacy retail price of the drug and a reference price. Reference prices are either externally (based on drug...... prices in other countries) or internally (based on domestic drug prices) determined. In a recent study, we analysed the effects of a change from external to internal reference pricing in Denmark in 2005, finding that the reform led to substantial reductions in prices, producer revenues, and expenditures...... for patients and the health insurance system. We also estimated an increase in consumer welfare but the size effect depends on whether or not perceived quality differences between branded and other drugs are taken into account....

The major objective of this reform is to provide medical service as a public service. In an interview with Beijing-based Guangming Daily, Li Weiping, a fellow researcher at the Institute of Medicine and Economy under the Ministry of Health, says that public hospitals are key to making this reform work and medical workers will need to drive this process forward.

  11. A reforming accountability: GPs and health reform in New Zealand.

    Jacobs, K

    1997-01-01

    Over the last ten years or so, many countries have undertaken public sector reforms. As a result of these changes, accounting has come to play a more important role. However, many of the studies have only discussed the reforms at a conceptual level and have failed to study how the reforms have been implemented and operated in practice. Based on the work of Lipsky (1980) and Gorz (1989), it can be argued that those affected by the reforms have a strong incentive to subvert the reforms. This prediction is explored via a case study of general practitioner (GP) response to the New Zealand health reforms. The creation of Independent Practice Associations (IPAs) allowed the State to impose contractual-accountability and to cap their budget exposure for subsidies. From the GP's perspective, the IPAs absorbed the changes initiated by the State, and managed the contracting, accounting and budgetary administration responsibilities that were created. This allowed individual GPs to continue practising as before and provided some collective protection against the threat of state intrusion into GP autonomy. The creation of IPAs also provided a new way to manage the professional/financial tension, the contradiction between the professional motivation noted by Gorz (1989) and the need to earn a living.

    Thermally activated hydrotalcite based upon a Zn/Al hydrotalcite with carbonate in the interlayer has been used to remove nitrate anions from an aqueous solution resulting in the reformation of a hydrotalcite with a mixture of nitrate and carbonate in the interlayer. X-ray diffraction of the reformed hydrotalcites with a d(003) spacing of 7.60 A shows that the nitrate anion is removed within a 30 min period. Raman spectroscopy shows that two types of nitrate anions exist in the reformed hydrotalcite (a) nitrate bonded to the 'brucite-like' hydrotalcite surface and (b) aquated nitrate anion in the interlayer. Kinetically the nitrate is replaced by the carbonate anion over a 21 h period. Two types of carbonate anions are observed. This research shows that the reformation of a thermally activated hydrotalcite can be used to remove anions such as nitrate from aqueous systems.

    Research in recent years has demonstrated the efficient use of solar thermal energy for driving endothermic chemical reforming reactions in which hydrocarbons are reacted to form synthesis gas (syngas). Closed-loop reforming/methanation systems can be used for storage and transport of process heat and for short-term storage for peaking power generation. Open-loop systems can be used for direct fuel production; for production of syngas feedstock for further processing to specialty chemicals and plastics and bulk ammonia, hydrogen, and liquid fuels; and directly for industrial processes such as iron ore reduction. In addition, reforming of organic chemical wastes and hazardous materials can be accomplished using the high-efficiency destruction capabilities of steam reforming. To help identify the most promising areas for future development of this technology, we discuss in this paper the economics and market potential of these applications.

    Restocking and stock enhancement programs are now recognized as an important tool for the management of fishery resources. It is important, however, to have an adequate knowledge on the genetic population structure of both the released stock and the wild population before carrying out such programs. In this study, random amplified polymorphic DNA (RAPD) markers were applied to assess genetic diversity and population structure of wild and hatchery populations of the white seabream Diplodus sargus and the common two-banded seabream D. vulgaris (Sparidae). The estimated values for intrapopulation genetic variation, measured using the percentage of polymorphic loci (%P), Shannon index (H'), and Nei's gene diversity (h), showed high values for all populations. The percentage of genetic variation within D. sargus and D. vulgaris populations, based on coefficient of gene differentiation, reached 82.5% and 90% of the total genetic variation, respectively. An undeniable decrease in genetic variation was found in both hatchery populations, particularly in D. sargus, compared to the wild ones. However, the high values of variation within all populations and the low levels of genetic variation among populations did not indicate inbreeding or depression effects, thus indicating a fairly proper hatchery management. Nevertheless, the results of this study highlight the importance of monitoring the genetic variation of hatchery populations, particularly those to be used in restocking programs. The creation of a genetic baseline database will contribute to a more efficient conservation management and to the design of genetically sustainable restocking programs.

    Reproductive success in wild- and first generation hatchery-origin spring Chinook males was examined by allowing the fish to compete for spawning opportunities in two sections of an observation stream. Behavioral observations were used to characterize the frequency of aggression and courting activities. Microsatellite DNA from each male and fry collected from the observation stream were used in pedigree analyses to estimate reproductive success. The coefficient of variation in male reproductive success equaled 116 and 86% in the two populations. No differences were detected in reproductive success due to hatchery or wild origin. Nor were any behavioral differences found between hatchery and wild males. Although statistical power was low due to intrinsic variation a great deal of overlap existed in the reproductive success values of hatchery and wild males. Significant disparities existed among the males on their ability to produce offspring. Males achieving high reproductive success mated with numerous females, were socially dominant, aggressive, and tended to stay in localized areas, courting and spawning with females that were adjacent to one another.

    This is the third in a series of annual reports that address reproductive ecological research and comparisons of hatchery and wild origin spring chinook in the Yakima River basin. Data have been collected prior to supplementation to characterize the baseline reproductive ecology, demographics and phenotypic traits of the unsupplemented upper Yakima population, however this report focuses on data collected on hatchery and wild spring chinook returning in 2003; the third year of hatchery adult returns. This report is organized into three chapters, with a general introduction preceding the first chapter and summarizes data collected between April 1, 2003 and March 31, 2004 in the Yakima basin. Summaries of each of the chapters in this report are included below. A major component of determining supplementation success in the Yakima Klickitat Fishery Project's spring chinook (Oncorhynchus tshawytscha) program is an increase in natural production. Within this context, comparing upper Yakima River hatchery and wild origin fish across traits such as sex ratio, age composition, size-at-age, fecundity, run timing and gamete quality is important because these traits directly affect population productivity and individual fish fitness which determine a population's productivity.

    Human salmonellosis linked to contact with live poultry is an increasing public health concern. In 2012, eight unrelated outbreaks of human salmonellosis linked to live poultry contact resulted in 517 illnesses. In July 2012, PulseNet, a national molecular surveillance network, reported a multistate cluster of a rare strain of Salmonella Braenderup infections which we investigated. We defined a case as infection with the outbreak strain, determined by pulsed-field gel electrophoresis, with illness onset from 25 July 2012-27 February 2013. Ill persons and mail-order hatchery (MOH) owners were interviewed using standardized questionnaires. Traceback and environmental investigations were conducted. We identified 48 cases in 24 states. Twenty-six (81%) of 32 ill persons reported live poultry contact in the week before illness; case-patients named 12 different MOHs from eight states. The investigation identified hatchery D as the ultimate poultry source. Sampling at hatchery D yielded the outbreak strain. Hatchery D improved sanitation procedures and pest control; subsequent sampling failed to yield Salmonella. This outbreak highlights the interconnectedness of humans, animals, and the environment and the importance of industry knowledge and involvement in solving complex outbreaks. Preventing these infections requires a 'One Health' approach that leverages expertise in human, animal, and environmental health.

    This report is intended to satisfy two concurrent needs: (1) provide a contract deliverable from Oncorh Consulting to the Washington Department of Fish and Wildlife (WDFW), with emphasis on identification of salient results of value to ongoing Yakima/Klickitat Fisheries Project (YKFP) planning, and (2) summarize results of research that have broader scientific relevance. This is the second in a series of reports that address reproductive ecological research and monitoring of spring chinook in the Yakima River basin. In addition to within-year comparisons, between-year comparisons will be made to determine if traits of the wild Naches basin control population, the naturally spawning population in the upper Yakima River and the hatchery control population are diverging over time. This annual report summarizes data collected between April 1, 2002 and March 31, 2003. In the future, these data will be compared to previous years to identify general trends and make preliminary comparisons. Supplementation success in the Yakima Klickitat Fishery Project's (YKFP) spring chinook (Oncorhynchus tshawytscha) program is defined as increasing natural production and harvest opportunities, while keeping adverse ecological interactions and genetic impacts within acceptable bounds (Busack et al. 1997). Within this context demographics, phenotypic traits, and reproductive ecology have significance because they directly affect natural productivity. In addition, significant changes in locally adapted traits due to hatchery influence, i.e. domestication, would likely be maladaptive resulting in reduced population productivity and fitness (Taylor 1991; Hard 1995). Thus, there is a need to study demographic and phenotypic traits in the YKFP in order to understand hatchery and wild population productivity, reproductive ecology, and the effects of domestication (Busack et al. 1997). Tracking trends in these traits over time is also a critical aspect of domestication monitoring (Busack

    In 2001 hatchery- and wild-origin spring chinook were placed into an observation stream located at the Cle Elum Supplementation Research Facility to compare their reproductive success. Two groups containing both wild- and hatchery fish of both sexes were brought into the stream and allowed to spawn. Their longevity, spawning participation, and reproductive success were assessed. In addition, wild- and hatchery-origin precocious males were also introduced into one of the sections and allowed to spawn. We found that hatchery and wild males generally lived longer than females. In one group hatchery and wild females lived for similar periods of time while in the other wild females lived longer than hatchery fish. Wild females were also more successful at burying their eggs and the eggs they buried had higher survival rates. This result occurred in both groups of fish. Spawning participation in males was estimated by using two statistics referred to as percent gonad depletion (PGD) and percent testes retention (PRT). Both of these measures assumed that loss of testes weight in males would reflect their spawning participation and therefore could be used to estimate reproductive success. Hatchery and wild males had similar PGD and PRT values. One of these measures, PRT, was negatively associated with male reproductive success, confirming the idea that reduction in testes weight can be used as a surrogate measure of a male's ability to produce offspring Fry from the observation stream were collected throughout the emergence period that ran from January through May. Proportionate sub-samples of these fish were removed and microsatellite DNA was extracted from them. Pedigree analyses were performed to ascertain which adult fish had produced them. These analyses disclosed that wild males were more successful at producing progeny in one of the groups. No difference occurred in the other group. Precocial males and jacks fathered fewer progeny than did fish maturing at ages

    Full Text Available This paper considers the social and structural policies in contemporary Europe. The presentation is organized in four sections. First, we discuss the emerging Europe, the new unity based on democracy and the market economy, the special European Union formula, and comparisons with America. Second, we analyze the dynamics of the European economy, the convergence process, the gaps between United States in productivity and standard of living, competitiveness issues, and the emergence of a new European economy and new European policy mix.Third, we consider European social conditions, the stationary and aging population, Europe’s low employment rate and permanently high unemployment. European economic growth could draw on two major sources: the labor reserves and reforms in factor, product and service markets. In a monetary union, advanced industrial relations should promote labor mobility and salary flexibility. The social security systems permit the redistribution and cohesion which defines the European model.Fourth, for the new Europe, the structural reform strategy is the way forward for the challenge of European economic policy and social policy: more and better jobs thanks to sustainable growth in a dynamic and competitive knowledge-based economy, favoring greater social cohesion.

    We report results from four years (1998-2001) of an ongoing study of survival and travel time of subyearling fall chinook salmon in the Snake River. We report analyses of associations among river conditions and survival and travel time estimates, which include data from 1995 through 1997. At weekly intervals from early June to early July each year (mid-May to late June in 2001), hatchery-reared subyearling fall chinook salmon were PIT tagged at Lyons Ferry Hatchery, trucked upstream, acclimated, and released above Lower Granite Dam at Pittsburgh Landing and Billy Creek on the Snake River and at Big Canyon Creek on the Clearwater River. Each year, a small proportion of fish released were not detected until the following spring. However, the number that overwintered in the river and migrated seaward as yearlings the following spring was small and had minimal effect on survival estimates. Concurrent with our studies, a number of subyearling fall chinook salmon that reared naturally in the Snake River were caught by beach seine, PIT tagged, and released. We compared a number of characteristics of hatchery and wild fish. Hatchery and wild fish were similar in 2001, and from 1995 through 1997. Results for 1998 through 2000 showed some relatively large differences between hatchery and wild fish. However, recent information suggests that a considerable proportion of wild subyearling chinook salmon migrating in a given year may actually be stream-type (spring/summer), rather than ocean-type (fall) fish, which may account for some of the differences we have observed.

    The timing of downstream migration and detection rates of hatchery-reared Atlantic salmon Salmo salar smolts and stream-reared smolts (stocked 2 years earlier as fry) were examined in the Connecticut River (U.S.A.) using passive integrated transponder (PIT) tags implanted into fish and then detected at a downstream fish bypass collection facility at Turners Falls, MA (river length 192 km). In two successive years, hatchery-reared smolts were released in mid-April and early May at two sites: the West River (river length 241 km) or the Passumpsic (river length 450 km). Hatchery-reared smolts released higher in the catchment arrived 7 to 14 days later and had significantly lower detection rates than smolts stocked lower in the catchment. Hatchery-reared smolts released 3 weeks apart at the same location were detected downstream at similar times, indicating that early-release smolts had a lower average speed after release and longer residence time. The size and gill Na+/K+-ATPase (NKA) activity of smolts at the time of release were significantly greater for detected fish (those that survived and migrated) than for those that were not detected. Stream-reared pre-smolts (>11·5 cm) from four tributaries (length 261–551 km) were tagged in autumn and detected during smolt migration the following spring. Stream-reared smolts higher in the catchment arrived later and had significantly lower detection rates. The results indicate that both hatchery and stream-reared smolts from the upper catchment will arrive at the mouth of the river later and experience higher overall mortality than fish from lower reaches, and that both size and gill NKA activity are related to survival during downstream migration.

    We address four main areas in which graduate quantum mechanics education in the U.S. can be improved: course content; textbook; teaching methods; and assessment tools. We report on a three year longitudinal study at the Colorado School of Mines using innovations in all four of these areas. In particular, we have modified the content of the course to reflect progress in the field in the last 50 years, use modern textbooks that include such content, incorporate a variety of teaching techniques based on physics education research, and used a variety of assessment tools to study the effectiveness of these reforms. We present a new assessment tool, the Graduate Quantum Mechanics Conceptual Survey, and further testing of a previously developed assessment tool, the Quantum Mechanics Conceptual Survey (QMCS). We find that graduate students respond well to research-based techniques that have previously been tested mainly in introductory courses, and that they learn a great deal of the new content introduced in each ve...

    Steam reforming (SR) of oxygenated species like bio-oil or ethanol can be used to produce hydrogen or synthesis gas from renewable resources. However, deactivation due to carbon deposition is a major challenge for these processes. In this study, different strategies to minimize carbon deposition...... on Ni-based catalysts during SR of ethanol were investigated in a flow reactor. Four different supports for Ni were tested and Ce0.6Zr0.4O2 showed the highest activity, but also suffered from severe carbon deposition at 600 °C or below. Operation at 600 °C or above were needed for full conversion...... 400 ppm of the carbon in the feed at approx. 600 °C. The different promoters did not influence the product distribution to any significant extent. Selective poisoning with small amounts of K2SO4 on Ni–CeO2/MgAl2O4 at 600 °C decreased carbon deposition from 900 to 200 ppm of the carbon in the feed...

  14. The effect of structural enrichment in hatchery tanks on the morphology of two neotropical fish species

    Directory of Open Access Journals (Sweden)

    Sarah de Oliveira Saraiva

    Full Text Available Reared fish differ from wild fish in several aspects, including morphology, because they are adapted to captive conditions that are totally different from natural conditions. To minimize the influence of the hatchery environment on the morphology of fish, the use of environmental enrichment through the incorporation of natural designs in captivity, has been proposed. In the present study, we performed the physical structuring of fish farming tanks to verify the enrichment effect on the morphology of two species of neotropical fishes: Prochilodus lineatus and Brycon orbignyanus. Each species was subjected to four different treatments over two months: tanks with submersed logs, with artificial aquatic plants, with both structures and without any structure. Results showed that the structural enrichment had a strong effect on the morphology of the cultured fish, which varied with each species analyzed and with the type of structural complexity added to the tanks. There was an increase of morphological variability in the population of P. lineatus and an increase of the average length in the population of B. orbignyanus. This shows that the environmental enrichment is capable to induce morphological differentiation through phenotypic plasticity, probably generating phenotypes more adapted to exploiting a complex environment. Peixes cultivados diferem de peixes selvagens em vários aspectos, incluindo morfologia, pois são adaptados às condições de cativeiro, que são totalmente diferentes das condições naturais. Para minimizar a influência do meio de cultivo sobre a morfologia dos peixes, o enriquecimento ambiental, através da incorporação de 'designs' naturais em cativeiro, tem sido proposto. No presente estudo, foi realizada a estruturação física de tanques de piscicultura para verificar o efeito deste tipo de enriquecimento ambiental sobre a morfologia de duas espécies de peixes neotropicais: Prochilodus lineatus e Brycon orbignyanus

  16. Let's make a deal: trading malpractice reform for health reform.

    Science.gov (United States)

    Sage, William M; Hyman, David A

    2014-01-01

    Physician leadership is required to improve the efficiency and reliability of the US health care system, but many physicians remain lukewarm about the changes needed to attain these goals. Malpractice liability-a sore spot for decades-may exacerbate physician resistance. The politics of malpractice have become so lawyer-centric that recognizing the availability of broader gains from trade in tort reform is an important insight for health policy makers. To obtain relief from malpractice liability, physicians may be willing to accept other policy changes that more directly improve access to care and reduce costs. For example, the American Medical Association might broker an agreement between health reform proponents and physicians to enact federal legislation that limits malpractice liability and simultaneously restructures fee-for-service payment, heightens transparency regarding the quality and cost of health care services, and expands practice privileges for other health professionals. There are also reasons to believe that tort reform can make ongoing health care delivery reforms work better, in addition to buttressing health reform efforts that might otherwise fail politically.

  17. Patterns of hybridization of nonnative cutthroat trout and hatchery rainbow trout with native redband trout in the Boise River, Idaho

    Science.gov (United States)

    Neville, Helen M.; Dunham, Jason B.

    2011-01-01

    Hybridization is one of the greatest threats to native fishes. Threats from hybridization are particularly important for native trout species as stocking of nonnative trout has been widespread within the ranges of native species, thus increasing the potential for hybridization. While many studies have documented hybridization between native cutthroat trout Oncorhynchus clarkii and nonnative rainbow trout O. mykiss, fewer have focused on this issue in native rainbow trout despite widespread threats from introductions of both nonnative cutthroat trout and hatchery rainbow trout. Here, we describe the current genetic (i.e., hybridization) status of native redband trout O. mykiss gairdneri populations in the upper Boise River, Idaho. Interspecific hybridization was widespread (detected at 14 of the 41 sampled locations), but high levels of hybridization between nonnative cutthroat trout and redband trout were detected in only a few streams. Intraspecific hybridization was considerably more widespread (almost 40% of sampled locations), and several local populations of native redband trout have been almost completely replaced with hatchery coastal rainbow trout O. mykiss irideus; other populations exist as hybrid swarms, some are in the process of being actively invaded, and some are maintaining genetic characteristics of native populations. The persistence of some redband trout populations with high genetic integrity provides some opportunity to conserve native genomes, but our findings also highlight the complex decisions facing managers today. Effective management strategies in this system may include analysis of the specific attributes of each site and population to evaluate the relative risks posed by isolation versus maintaining connectivity, identifying potential sites for control or eradication of nonnative trout, and long-term monitoring of the genetic integrity of remaining redband trout populations to track changes in their status.

  18. Survival, movement, and health of hatchery-raised juvenile Lost River suckers within a mesocosm in Upper Klamath Lake, Oregon

    The recovery of endangered Lost River suckers (Deltistes luxatus) in Upper Klamath Lake is limited by poor juvenile survival and failure to recruit into the adult population. Poor water quality, degradation of rearing habitat, and toxic levels of microcystin are hypothesized to contribute to low juvenile survival. Studies of wild juvenile suckers are limited in that capture rates are low and compromised individuals are rarely captured in passive nets. The goal of this study was to assess the use of a mesocosm for learning about juvenile survival, movement, and health. Hatchery-raised juvenile Lost River suckers were PIT (passive integrated transponder) tagged and monitored by three vertically stratified antennas. Fish locations within the mesocosm were recorded at least every 30 minutes and were assessed in relation to vertically stratified water-quality conditions. Vertical movement patterns were analyzed to identify the timing of mortality for each fish. Most mortality occurred from July 28 to August 16, 2014. Juvenile suckers spent daylight hours near the benthos and moved throughout the entire water column during dark hours. Diel movements were not in response to dissolved-oxygen concentrations, temperature, or pH. Furthermore, low dissolved-oxygen concentrations, high temperatures, high pH, high un-ionized ammonia, or high microcystin levels did not directly cause mortality, although indirect effects may have occurred. However, water-quality conditions known to be lethal to juvenile Lost River suckers did not occur during the study period. Histological assessment revealed severe gill hyperplasia and Ichthyobodo sp. infestations in most moribund fish. For these fish, Ichthyobodo sp. was likely the cause of mortality, although it is unclear if this parasite originated in the rearing facility because fish were not screened for this parasite prior to introduction. This study has demonstrated that we can effectively use a mesocosm equipped with antennas to learn

    This study aims to examine whether there is particularly anything to be supplemented in order to successfully reform the price system, based on the assumption of maintaining the current proposal for price reforming. To achieve the target, we compare and evaluate the tax structure and proportion to the advanced taxation system through surveying on the taxation system of the advanced countries and investigate the measures for advancing the energy tax system. Through benchmarking USA, Japan, and European countries, we understand the contents about taxation system, revenue, and future tax reformation related to energy and draw an appropriated conclusion about energy taxation system. On the basis of these analyzed data about the advanced countries' taxation system, we objectively appraise the reforming proposal of our energy price system and examine what needs to be improved and supplemented. Accordingly, we deduce necessary measures for improvement and estimate the expected national economic effects in case of enforcing the improving measures actually. To estimate the economic effects, we also estimate the effects that the price reform impacts on increase and decrease of tax revenue and find an effective expenditure measures for increasing tax revenue. 36 refs., 26 figs., 111 tabs.

  20. The Missing Link in Housing Sector Reforms in Nigeria

    2012-09-01

    Full Text Available Housing is a fundamental product for every human being irrespective of financial standing. World acclaimed American psychologist, Abraham Maslow ranked shelter as second only to food in his hierarchy of human needs. Despite the importance of housing to the socio-economic development of man and the nation, housing problems have remained endemic throughout the world. In today’s world, some 100 million persons are homeless and more than a billion are inadequately housed. In 2002 housing deficit in Nigeria was put at about 8 million units. Latest statistics indicate that Nigeria requires a whopping 700,000 housing units annually for the next 15 years. The question is why this state of affairs? Why the perennial and unending problems of housing shortages, forced evictions and slum development? The paper examined these issues in Nigeria in order to advance the future prospect of the sector. The paper identified that whilst reforms were been made to all other subsector of the housing industry, land reform necessary to fast track the process was left unattended to by the government. The paper thus advocated for a robust reform of the current land management system in order to impact positively on the housing reform agenda in Nigeria.

  1. Can ICT Reform Public Agencies?

    Science.gov (United States)

    Jansen, Arild; Løvdal, Einar

    This study examines the reorganisation of the administration of admission to higher education in Norway, which has also included the development of a nationwide, ICT-based case handling system. This reform process was initiated out of the need to provide politicians with information for control and regulatory purposes, and the reform resulted in a centralised management information system. This system, however, has evolved into a coordinated but also partly locally delegated decision-making instrument which processes most of the applications for admission to higher education in Norway.

    How does central bank conservatism affect labor market reform? In this paper we examine the economic forces at work. An increase in conservatism triggers two opposite effects. It reduces the inflation bias of discretionary monetary policy and hence the benefits of a reform. It also increases unemployment variability, which increases the precautionary benefits of a reform. In combination, the two effects produce a u-shaped relation between conservatism and labor market reform. An empirical inv...

    McClellan, Mark B; Thoumi, Andrea I

    2015-05-01

    Cancer care is transforming, moving toward increasingly personalized treatment with the potential to save and improve many more lives. Many oncologists and policymakers view current fee-for-service payments as an obstacle to providing more efficient, high-quality cancer care. However, payment reforms create new uncertainties for oncologists and may be challenging to implement. In this article, we illustrate how accountable care payment reforms that directly align payments with quality and cost measures are being implemented and the opportunities and challenges they present. These payment models provide more flexibility to oncologists and other providers to give patients the personalized care they need, along with more accountability for demonstrating quality improvements and overall cost or cost growth reductions. Such payment reforms increase the importance of person-level quality and cost measures as well as data analysis to improve measured performance. We describe key features of quality and cost measures needed to support accountable care payment reforms in oncology. Finally, we propose policy recommendations to move incrementally but fundamentally to payment systems that support higher-value care in oncology.

    2003-01-01

    To meet the demands for high-octane gasoline and aromatics, catalytic reforming process has been advancing quickly in China. The reforming catalysts developed by RIPP have been used in more than 80% capacity of domestic CCR and SR units. This paper introduces the properties of PS-VI CCR catalyst developed by RIPP in recent years and also the result from commercial units. The PS-VI catalyst has high activity and good selectivity, under the same reaction conditions, the carbon on catalyst was lowered by 26% in mass as compared with that of the reference catalyst. Among the SR reforming catalysts, the new type of PRT series catalysts have excellent performance at low reaction pressure compared with the ref. Cat A. The aromatics and reformate mass yields of PRT catalyst were 2%~3% and 3%, respectively, higher than those of Cat A, and the run length was 30%~40% longer as well, which exhibits good prospect of application.

  11. Monitoring the Reproductive Success of Naturally Spawning Hatchery and Natural Spring Chinook Salmon in the Wenatchee River, 2008-2009 Progress Report.

    We investigated differences in the statistical power to assign parentage between an artificially propagated and wild salmon population. The propagated fish were derived from the wild population, and are used to supplement its abundance. Levels of genetic variation were similar between the propagated and wild groups at 11 microsatellite loci, and exclusion probabilities were >0.999999 for both groups. The ability to unambiguously identify a pair of parents for each sampled progeny was much lower than expected, however. Simulations demonstrated that the proportion of cases the most likely pair of parents were the true parents was lower for propagated parents than for wild parents. There was a clear relationship between parentage assignment ability and the degree of linkage disequilibrium, the estimated effective number of breeders that produced the parents, and the size of the largest family within the potential parents. If a stringent threshold for parentage assignment was used, estimates of relative fitness were biased downward for the propagated fish. The bias appeared to be largely eliminated by either fractionally assigning progeny among parents in proportion to their likelihood of parentage, or by assigning progeny to the most likely set of parents without using a statistical threshold. We used a DNA-based parentage analysis to measure the relative reproductive success of hatchery- and natural-origin spring Chinook salmon in the natural environment. Both male and female hatchery-origin fish produced far fewer juvenile progeny per parent when spawning naturally than did natural origin fish. Differences in age structure, spawning location, weight and run timing were responsible for some of the difference in fitness. Male size and age had a large influence on fitness, with larger and older males producing more offspring than smaller or younger individuals. Female size had a significant effect on fitness, but the effect was much smaller than the effect of size on

    2000-11-01

    Since the 1980's psychiatric care in Spain changed considerably (Reforma psiquiátrica española). In the course of this reform, many positive results were achieved. An extensive community network of mental health centres was build up which resulted in the majority of psychiatric patients being integrated in the Spanish general health care system and making a better organized mental health care structure possible. New legislation also improved the care and civil rights of patients. An analysis of the experiences of the Spanish psychiatric reform shows that the tendency to retain the old mental hospitals, alongside the other institutions still exists. The process of deinstitutionalization and the original aims of the psychiatric reform cannot only be satisfied by the closure of large psychiatric hospitals as during the reform new aspects and problems as well the great complexity of the task have become apparent. This article together with the details of the Spanish sources gives the German public a good overview of the developments in Spanish psychiatry.

    2002-09-01

    The catalytic reforming of naphtha is one of the major refinery processes, designed to increase the octane number of naphtha or to produce aromatics. The naphtha used as catalytic reformer feedstock usually contains a mixture of paraffins, naphthenes, and aromatics in the carbon number range C{sub 6} to C{sub 10}. The detailed chemical composition of the feed is necessary to predict the aromatics and hydrogen production as well as the operation severity. The analysis of feed naphtha is usually reported in terms of its ASTM distillation curve and API or specific gravity. Since reforming reactions are described in terms of lumped chemical species (paraffins, naphthenes and aromatics), a feed characterisation technique should be useful in order to predict reforming operating conditions and detect feed quality changes. Unfortunately online analyzer applications as cromatography or recently introduced naphtha NMR [1] are scarce in most of refineries. This work proposes an algorithmic characterisation method focusing on its main steps description. The method could help on the subjects previously described, finally a calculation example is shown.

  19. Negative Valve Overlap Reforming Chemistry in Low-Oxygen Environments

    Fuel injection into the negative valve overlap (NVO) period is a common method for controlling combustion phasing in homogeneous charge compression ignition (HCCI) and other forms of advanced combustion. When fuel is injected into O2-deficient NVO conditions, a portion of the fuel can be converted to products containing significant levels of H2 and CO. Additionally, other short chain hydrocarbons are produced by means of thermal cracking, water-gas shift, and partial oxidation reactions. The present study experimentally investigates the fuel reforming chemistry that occurs during NVO. To this end, two very different experimental facilities are utilized and their results are compared. One facility is located at Oak Ridge National Laboratory, which uses a custom research engine cycle developed to isolate the NVO event from main combustion, allowing a steady stream of NVO reformate to be exhausted from the engine and chemically analyzed. The other experimental facility, located at Sandia National Laboratories, uses a dump valve to capture the exhaust from a single NVO event for analysis. Results from the two experiments are in excellent trend-wise agreement and indicate that the reforming process under low-O2 conditions produces substantial concentrations of H2, CO, methane, and other short-chain hydrocarbon species. The concentration of these species is found to be strongly dependent on fuel injection timing and injected fuel type, with weaker dependencies on NVO duration and initial temperature, indicating that NVO reforming is kinetically slow. Further, NVO reforming does not require a large energy input from the engine, meaning that it is not thermodynamically expensive. The implications of these results on HCCI and other forms of combustion are discussed in detail.

  20. After Medicare: regionalization and Canadian health care reform.

    2009-01-01

    In the immediate postwar era the primary object of health reform among the advanced industrial democracies was to expand, if not universalize, access to a broad spectrum of health services through sustained, high levels of government-mandated spending. The fiscal crises of the 1970s and 1980s ushered in a new generation of policies devoted to balancing the imperatives of guaranteeing access to basic health and social services and to improving the accountability, efficiency, and effectiveness of health care industries. In Canada, the regionalization of health care administration emerged as the most prominent strategy for grappling with the contradictions and paradoxes of contemporary health reform. This essay traces the historical evolution of federal-provincial deliberations that elevated regionalization to the forefront of health policy-making in the new era of fiscal restraint, and further, assesses recent efforts to institutionalize regional health authorities.

    1995-08-01

    Two streams in the Imnaha River subbasin (Camp Creek and Little Sheep Creek) and eight streams in the Grande Ronde River subbasin (Catherine, Deer, Five Points, Fly, Indian, Lookingglass, Meadow, and Sheep creeks) were selected as study streams to evaluate the success and impacts of steelhead supplementation in northeast Oregon. The habitat of the study streams was inventoried to compare streams and to evaluate whether habitat might influence the performance parameters we will measure in the study. The mean fecundity of hatchery and natural steelhead 1-salts returning to Little Sheep Creek fish facility in 1990 and 1991 ranged from 3,550 to 4,663 eggs/female; the mean fecundity of hatchery and natural steelhead 2-salts ranged from 5,020 to 5,879 eggs/female. Variation in length explained 57% of the variation in fecundity of natural steelhead, but only 41% to 51% of the variation in fecundity of hatchery steelhead. Adult steelhead males had an average spermatocrit of 43.9% at spawning. We were also able to stain sperm cells so that viable cells could be distinguished from dead cells. Large, red disc tags may be the most useful for observing adults on the spawning grounds. The density of wild, juvenile steelhead ranged from 0 fish/l00{sup 2} to 35.1 (age-0) and 14.0 (age-1) fish/l00m{sup 2}. Evidence provided from the National Marine Fisheries Service suggests that hatchery and wild fish within a subbasin are genetically similar. The long-term experimental design is presented as a component of this report.

    1989-10-01

    In 1979 this study was initiated to determine the distribution, contribution, and value of artificially propagated fall chinook salmon from the Columbia River. Coded wire tagging (CWT) of hatchery fall chinook salmon began in 1979 with the 1978 brood and was completed in 1982 with the 1981 brood of fish at rearing facilities on the Columbia River system. From 18 to 20 rearing facilities were involved in the study each brood year. Nearly 14 million tagged fish, about 4% of the production, were released as part of this study over the four years, 1979 through 1982. Sampling for recoveries of these tagged fish occurred from 1980 through 1986 in the sport and commercial marine fisheries from Alaska through California, Columbia River fisheries, and returns to hatcheries and adjacent streams. The National Marine Fisheries Service coordinated this study among three fishery agencies: US Fish and Wildfire Service, Oregon Department of Fish and Wildlife, and Washington Department of Fisheries. The objectives of this study were to determine the distribution, fishery contribution, survival, and value of the production of fall chinook salmon from each rearing facility on the Columbia River system to Pacific coast salmon fisheries. To achieve these objectives fish from each hatchery were given a distinctive CWT. 81 refs., 20 figs., 68 tabs.

  3. Loss of genetic variation in Greek hatchery populations of the European sea bass (Dicentrarchus labrax L. as revealed by microsatellite DNA analysis

    Directory of Open Access Journals (Sweden)

    D. LOUKOVITIS

    2015-01-01

    Full Text Available Genetic variation in four reared stocks of European sea bass Dicentrarchus labrax L., originating from Greek commercial farms, was assessed using five polymorphic microsatellite markers and was compared with that of three natural populations from Greece and France. The total number of alleles per marker ranged from 8 to 22 alleles, and hatchery samples showed the same levels of observed heterozygosity with samples from the wild but substantially smaller allelic richness and expected heterozygosity. The genetic differentiation of cultivated samples between them as well as from the wild origin fish was significant as indicated by Fst analysis. All population pairwise comparisons were statistically significant, except for the pair of the two natural Greek populations. Results of microsatellite DNA analysis herein showed a 37 % reduction of the mean allele number in the hatchery samples compared to the wild ones, suggesting random genetic drift and inbreeding events operating in the hatcheries. Knowledge of the genetic variation in D. labrax cultured populations compared with that in the wild ones is essential for setting up appropriate guidelines for proper monitoring and management of the stocks either under traditional practices or for the implementation of selective breeding programmes.

    This report is intended to satisfy two concurrent needs: (1) provide a contract deliverable from Oncorh Consulting to the Washington Department of Fish and Wildlife (WDFW), with emphasis on identification of salient results of value to ongoing Yakima/Klickitat Fisheries Project (YKFP) planning and (2) summarize results of research that have broader scientific relevance. This is the fourth in a series of reports that address reproductive ecological research and monitoring of spring chinook populations in the Yakima River basin. This annual report summarizes data collected between April 1, 2004 and March 31, 2005 and includes analyses of historical baseline data, as well. Supplementation success in the Yakima Klickitat Fishery Project's (YKFP) spring chinook (Oncorhynchus tshawytscha) program is defined as increasing natural production and harvest opportunities, while keeping adverse ecological interactions and genetic impacts within acceptable bounds (Busack et al. 1997). Within this context demographics, phenotypic traits, and reproductive ecology have significance because they directly affect natural productivity. In addition, significant changes in locally adapted traits due to hatchery influence, i.e. domestication, would likely be maladaptive resulting in reduced population productivity and fitness (Taylor 1991; Hard 1995). Thus, there is a need to study demographic and phenotypic traits in the YKFP in order to understand hatchery and wild population productivity, reproductive ecology, and the effects of domestication (Busack et al. 1997). Tracking trends in these traits over time is also a critical aspect of domestication monitoring (Busack et al. 2004) to determine whether trait changes have a genetic component and, if so, are they within acceptable limits. The first chapter of this report compares first generation hatchery and wild upper Yakima River spring chinook returns over a suite of life-history, phenotypic and demographic traits. The second

    2010-09-01

    In order to study the infection dynamics of 2 renal myxozoans, Zschokkella hildae Auerbach, 1910 and Gadimyxa atlantica Køie, Karlsbakk and Nylund, 2007 in cultured Atlantic cod, Gadus morhua L. aged 3-19 months, a specific single-round PCR assay and a double-label in situ hybridization protocol were developed. The results demonstrated that the 2 myxozoans show spatial separation of their development with regard to spore formation inside the renal tubules versus the collecting ducts and ureters, as well as temporal separation with Z. hildae proliferating and developing spores only once the G. atlantica infection decreases, despite the presence of both myxozoans in the smallest fry studied. These results strongly suggest within-host competition of the 2 myxozoans with potential suppression of Z. hildae by G. atlantica until G. morhua acquires immunity against G. atlantica. The quantification of the G. atlantica infection inside the renal tubules before and after a 29-day experimental growth performance study using fry from hatcheries with differing filtration systems showed that the intensity of infection with G. atlantica seems to be controlled if prolonged exposure to the myxozoan transmission stages takes place from hatching onwards. Surprisingly, growth rates in the trial were inversely affected suggesting that G. atlantica does not negatively influence cod fry growth performance.

    2011-05-01

    The feeding and growth of hatchery-reared (HR) Japanese flounder Paralichthys olivaceus of c. 100 mm total length (L(T) ) released off the coast of Fukushima, Japan, were investigated. From 2 to 15 days after release, the HR P. olivaceus frequently exhibited high empty-stomach frequency (>40%), low stomach-content mass (<1% of body mass), reduced somatic condition from release (c.-10%) and negligible growth. Thereafter, empty-stomach frequency decreased, the stomach-content mass of HR fish increased to 2-8% of body mass, the somatic condition recovered and growth rate increased to 0·5-1·5 mm day(-1) . Prey items were initially mysids, shifting thereafter to fishes such as the Japanese anchovy Engraulis japonica, as observed similarly in wild counterparts. The proportion of mysids decreased with time after release irrespective of size at release, indicating the importance of mysids for adaptation to natural food. Recapture rates at age 1 year, derived from fish market surveys, varied greatly among release years (4-11%). The variation in the recapture rates was largely accounted for by the post-release growth rates (r(2) = 0·5), suggesting a relationship between the post-release growth of HR fish and their survival and subsequent stocking effectiveness.

    2002-02-01

    The Comparative Survival Study (CSS) was initiated in 1996 as a multi-year program of the fishery agencies and tribes to estimate survival rates over different life stages for spring and summer chinook (hereafter, chinook) produced in major hatcheries in the Snake River basin and from selected hatcheries in the lower Columbia River. Much of the information evaluated in the CSS is derived from fish tagged with Passive Integrated Transponder (PIT) tags. A comparison of survival rates of chinook marked in two different regions (which differ in the number of dams chinook have to migrate through) provides insight into the effects of the Snake/Columbia hydroelectric system (hydrosystem). The CSS also compares the smolt-to-adult survival rates (SARs) for Snake River chinook that were transported versus those that migrated in-river to below Bonneville Dam. Additional comparisons can be made within in-river experiences as well comparison between the different collector projects from which smolts are transported. CSS also compares these survival rates for wild Snake River spring and summer chinook. These comparisons generate information regarding the relative effects of the current management actions used to recover this listed species.Scientists and managers have recently emphasized the importance of delayed hydrosystem mortality to long-term management decisions. Delayed hydrosystem mortality may be related to the smolts. experience in the Federal Columbia River Power System, and could occur for both smolts that migrate in-river and smolts that are transported. The CSS PIT tag information on in-river survival rates and smolt-to-adult survival rates (SARs) of transported and in-river fish are relevant to estimation of ''D'', which partially describes delayed hydrosystem mortality. ''D'', or differential delayed mortality, is the differential survival rate of transported fish relative to fish that migrate in-river, as measured from

The Sherman Creek Hatchery, located on a tributary of Lake Roosevelt to provide an egg collection and imprinting site, is small with limited rearing capability. The second hatchery was located on the Spokane Indian Reservation because of a spring water source that supplied cold, pure water for incubating and rearing eggs.`The Spokane Tribal Hatchery thus serves as the production facility. Fish reared there are released into Sherman Creek and other tributary streams as 7-9 month old fry. However, to date, returns of adult fish to release sites has been poor. If hatchery reared kokanee imprint to the hatchery water at egg or swim up stages before 3 months of age, they may not be imprinting as 7-9 month old fry at the time of stocking. In addition, if these fish undergo a smolt phase in the reservoir when they are 1.5 years old, they could migrate below Grand Coulee Dam and out of the Lake Roosevelt system. In the present investigation, which is part of the Lake Roosevelt monitoring program to assess hatchery effectiveness, kokanee salmon were tested to determine if they experienced thyroxine-induced chemical imprinting and smoltification similar to anadromous salmonids. Determination of the critical period for olfactory imprinting was determined by exposing kokanee to different synthetic chemicals (morpholine or phenethyl alcohol) at different life stages, and then measuring the ability to discriminate the chemicals as sexually mature adults. Whole body thyroxine content and blood plasma thyroxine concentration was measured to determine if peak thyroid activity coincided with imprinting or other morphological, physiological or behavioral transitions associated with smoltification.

    Full Text Available Intercountry adoption (ICA is a relatively common practice. Since its contemporary conception during the Second World War, approximately one million children have been adopted internationally. Controversy surrounding ICA includes ideas about human rights and notions of child rescue in the context of major reform to prevent child sales and abduction under the Hague Convention on Intercountry Adoption. Social work, as a discipline, is a central player in ICA practices, and at least, one historian asserts that social work academic literature is scant on the topic of problematic practice and reforms. A review of the social work literature was conducted, and four thematic areas emerged in the 87 manuscripts reviewed: (a social policy; (b exploitation, social justice, ethics, and human rights; (c clinical perspectives to include identity, child development, and family transition; and (d child welfare practices. Results indicate a small but robust body of social work literature, and highlights are presented as well as analysis indicating methodical trends.

    Thermal plasma technology can be efficiently used in the production of hydrogen and hydrogen-rich gases from methane and a variety of fuels. This paper describes progress in plasma reforming experiments and calculations of high temperature conversion of methane using heterogeneous processes. The thermal plasma is a highly energetic state of matter that is characterized by extremely high temperatures (several thousand degrees Celsius) and high degree of dissociation and substantial degree of ionization. The high temperatures accelerate the reactions involved in the reforming process. Hydrogen-rich gas (50% H{sub 2}, 17% CO and 33% N{sub 2}, for partial oxidation/water shifting) can be efficiently made in compact plasma reformers. Experiments have been carried out in a small device (2--3 kW) and without the use of efficient heat regeneration. For partial oxidation/water shifting, it was determined that the specific energy consumption in the plasma reforming processes is 16 MJ/kg H{sub 2} with high conversion efficiencies. Larger plasmatrons, better reactor thermal insulation, efficient heat regeneration and improved plasma catalysis could also play a major role in specific energy consumption reduction and increasing the methane conversion. A system has been demonstrated for hydrogen production with low CO content ({approximately} 1.5%) with power densities of {approximately} 30 kW (H{sub 2} HHV)/liter of reactor, or {approximately} 10 m{sup 3}/hr H{sub 2} per liter of reactor. Power density should further increase with increased power and improved design.

    2007-07-01

    India faces endemic electrical energy and peaking shortages. The Power Sector is plagued with mounting commercial losses due various inefficiencies, colossal commercial and technical losses and increasing subsidy burden on the states. These shortages have had a very detrimental effect on the overall economic growth of the country. In order to re-vitalise the sector and improve the techno-economic performance, the Government of India has initiated the reform process in 1991. This paper analyses the pre-reform era and identifies the key concerns which led to the initiation of the reforms. It also analyses the likely impact of the major policy and regulatory initiatives that have been undertaken since 1991 including the provisions of the new enactments which have come into force eventually in the form of The Electricity Act, 2003. This paper details out the key features of the Act and its likely impact on the Indian electricity industry in the emerging scenario. The paper also discusses major issues like power trading, role of regulator in the new regime, issue of open access, introduction of power markets and role of Appellate Tribunal for Electricity in harmonizing the orders of the various regulators.

    1995-09-01

    Since 1991, the National Science Foundation has signed cooperative agreements with 26 states to undertake ambitious and comprehensive initiatives to reform science, mathematics, and technology education. Collectively, those agreements are known as the State Systemic Initiatives (SSI's). Two complimentary programs, The Urban and Rural Systemic Initiatives (USI's and RSI's), address similar reforms in the nation's largest cities and poorest rural areas. The SSI Program departs significantly from past NSF practice in several ways. The funding is for a longer term and is larger in amount, and the NSF is taking a more activist role, seeking to leverage state and private funds and promote the coordination of programs within states. The Initiatives also have a stronger policy orientation than previous NSF programs have had. The NSF strategy is a reflection of the growing and widely held view that meaningful reforms in schools are most likely to be achieved through state initiatives that set clear and ambitious learning goals and standards; align all of the available policy levers in support of reform; stimulate school-level initiatives; and mobilize human and financial resources to support these changes. Two premises underlie systemic reform: (1) all children can meet significantly higher standards if they are asked to do so and given adequate opportunities to master the content, and (2) state and local policy changes can create opportunities by giving schools strong and consistent signals about the changes in practice and performance that are expected. Because this is an enormous investment of Federal resources that is intended to bring about deep, systemic improvement in the nation's ability to teach science and mathematics effectively, the NSF has contracted with a consortium of independent evaluators to conduct a review of the program. The first of the SSI's were funded in 1991, sufficiently long ago to begin to formulate some initial impressions of their impact. Take

    In 2001 hatchery- and wild-origin spring chinook were placed into an observation stream located at the Cle Elum Supplementation Research Facility to compare their reproductive success. Two groups containing both wild- and hatchery fish of both sexes were brought into the stream and allowed to spawn. Their longevity, spawning participation, and reproductive success were assessed. In addition, wild- and hatchery-origin precocious males were also introduced into one of the sections and allowed to spawn. We found that hatchery and wild males generally lived longer than females. In one group hatchery and wild females lived for similar periods of time while in the other wild females lived longer than hatchery fish. Wild females were also more successful at burying their eggs and the eggs they buried had higher survival rates. This result occurred in both groups of fish. Spawning participation in males was estimated by using two statistics referred to as percent gonad depletion (PGD) and percent testes retention (PRT). Both of these measures assumed that loss of testes weight in males would reflect their spawning participation and therefore could be used to estimate reproductive success. Hatchery and wild males had similar PGD and PRT values. One of these measures, PRT, was negatively associated with male reproductive success, confirming the idea that reduction in testes weight can be used as a surrogate measure of a male's ability to produce offspring Fry from the observation stream were collected throughout the emergence period that ran from January through May. Proportionate sub-samples of these fish were removed and microsatellite DNA was extracted from them. Pedigree analyses were performed to ascertain which adult fish had produced them. These analyses disclosed that wild males were more successful at producing progeny in one of the groups. No difference occurred in the other group. Precocial males and jacks fathered fewer progeny than did fish maturing at ages

    This case study of Kenyan business trade licensing shows that red-tape costs can be cut if reform is championed strongly and there is a strong case in terms of costs and benefits. The reform of business registration, trade licensing and other business entry procedures is a cost effective and progressive way to promote indigenous private sector development. But, reform needs more than good cost-benefit analysis and legal drafting; it also requires building constituencies and continuous advocacy.

    Fuel processors for on-board hydrogen production have to meet numerous technical demands. They should be efficient, compact and lightweight, capable of different loads and able to perform cold start ups. In this paper, the recirculation of reformate is proposed as a means of efficiency enhancement. Different system configurations based on this idea are introduced and simulated. The resulting effect on the system's efficiency, the water balance as well as the impact of recirculation on the system's volume and weight are discussed. (author)

  11. Inter-population differences in salinity tolerance and osmoregulation of juvenile wild and hatchery-born Sacramento splittail

    The Sacramento splittail (Pogonichthys macrolepidotus) is a minnow endemic to the highly modified San Francisco Estuary of California, USA and its associated rivers and tributaries. This species is composed of two genetically distinct populations, which, according to field observations and otolith strontium signatures, show largely allopatric distribution patterns as recently hatched juveniles. Juvenile Central Valley splittail are found primarily in the nearly fresh waters of the Sacramento and San Joaquin rivers and their tributaries, whereas San Pablo juveniles are found in the typically higher-salinity waters (i.e. up to 10‰) of the Napa and Petaluma Rivers. As the large salinity differences between young-of-year habitats may indicate population-specific differences in salinity tolerance, we hypothesized that juvenile San Pablo and Central Valley splittail populations differ in their response to salinity. In hatchery-born and wild-caught juvenile San Pablo splittail, we found upper salinity tolerances, where mortalities occurred within 336 h of exposure to 16‰ or higher, which was higher than the upper salinity tolerance of 14‰ for wild-caught juvenile Central Valley splittail. This, in conjunction with slower recovery of plasma osmolality, but not ion levels, muscle moisture or gill Na+,K+-ATPase activity, in Central Valley relative to San Pablo splittail during osmoregulatory disturbance provides some support for our hypothesis of inter-population variation in salinity tolerance and osmoregulation. The modestly improved salinity tolerance of San Pablo splittail is consistent with its use of higher-salinity habitats. Although confirmation of the putative adaptive difference through further studies is recommended, this may highlight the need for population-specific management considerations.

  12. The effect of hatchery release strategy on marine migratory behaviour and apparent survival of Seymour River steelhead smolts (Oncorhynchus mykiss.

    Shannon Balfry

    Full Text Available Early marine migratory behaviour and apparent survival of hatchery-reared Seymour River steelhead (Oncorhynchus mykiss smolts was examined over a four year period (2006-2009 to assess the impact of various management strategies on improving early marine survival. Acoustically tagged smolts were released to measure their survival using estuary and coastal marine receivers forming components of the Pacific Ocean Shelf Tracking (POST array. Early marine survival was statistically indistinguishable between releases of summer run and winter run steelhead races, night and day releases, and groups released 10 days apart. In 2009, the survival of summer run steelhead released into the river was again trialed against groups released directly into the ocean at a distance from the river mouth. Apparent survival was improved significantly for the ocean released groups. The health and physiological status of the various release groups were monitored in years 2007-2009, and results indicate that the fish were in good health, with no clinical signs of disease at the time of release. The possibility of a disease event contributing to early marine mortality was further examined in 2009 by vaccinating half of the released fish against common fish diseases (vibriosis, furunculosis. The results suggest that marine survival may be enhanced using this approach, although not to the extent observed when the smolts were transported away from the river mouth before release. In summary, direct experimental testing of different release strategies using the POST array to measure ocean survival accelerated the scientific process by allowing rapid collection of data which enabled the rejection of several existing theories and allowed tentative identification of several new alternative approaches that might improve early marine survival of Seymour River steelhead.

    The current epidemiological situation of viral nervous necrosis virus (VNNV) on Hainan Island was investigated. A total of 490 hatchery-reared fish and 652 wild fish were sampled for VNNV detection from March 2013 to May 2014. Positive detection rates of 84.53% (153/181) and 0.97 % (3/309) were obtained in diseased and healthy hatchery-reared samples, respectively, by conventional RT-PCR. However, using more-sensitive nested RT-PCR, the positive detection rates in healthy hatchery-reared fish reached up to 64.08% (198/309), suggesting that asymptomatic VNNV carriers commonly exist among larvae and juveniles breeding on Hainan Island. In wild-fish samples, 2.6% (17/652) and 34.2% (223/652) positive detection rates were observed using RT-PCR and nested RT-PCR, respectively, indicating that wild fish may be a potential reservoir for VNNV. Phylogenetic analysis showed that all 52 VNNV isolates from cultured fish belong to the RGNNV genotype, but 2 out of 48 VNNV isolates from wild fish samples were found to be of the SJNNV genotype. This study is the first to confirm the existence of SJNNV-genotype VNNV in China. Golden pompano, an important fish species for culture, was selected as a fish model to investigate the optimal conditions for RGNNV disease progression in artificial infection experiments. The effects of temperature, salinity, and fish size were evaluated. Results showed that 28 °C and 20 ‰ are the optimal infection temperature and salinity, respectively, and golden pompano juveniles with small body sizes are more susceptible to RGNNV. These findings are highly consistent with those conditions involved in the natural outbreak of RGNNV.

    2003-08-01

    The Yakima River Spring Chinook Salmon Supplementation Project in Washington State is currently one of the most ambitious efforts to enhance a natural salmon population in the United States. Over the past five years we have conducted research to characterize the developmental physiology of naturally- and hatchery-reared wild progeny spring chinook salmon (Oncorhynchus tshawytscha) in the Yakima River basin. Fish were sampled at the main hatchery in Cle Elum, at remote acclimation sites and, during smolt migration, at downstream dams. Throughout these studies the maturational state of all fish was characterized using combinations of visual and histological analysis of testes, gonadosomatic index (GSI), and measurement of plasma 11-ketotestosterone (11-KT). We established that a plasma 11-KT threshold of 0.8 ng/ml could be used to designate male fish as either immature or precociously maturing approximately 8 months prior to final maturation (1-2 months prior to release as 'smolts'). Our analyses revealed that 37-49% of the hatchery-reared males from this program undergo precocious maturation at 2 years of age and a proportion of these fish appear to residualize in the upper Yakima River basin throughout the summer. An unnaturally high incidence of precocious male maturation may result in loss of potential returning anadromous adults, skewing of female: male sex ratios, ecological, and genetic impacts on wild populations and other native species. Precocious male maturation is significantly influenced by growth rate at specific times of year and future studies will be conducted to alter maturation rates through seasonal growth rate manipulations.

    China's decades of rapid growth has led some to hail the success of "state capitalism." Others say the state's hand is less important. Researcher Zhang Wenkui at the State Council's Development Research Center is in the second camp. State companies and industrial administrators have had roles to play in leading the economy. But more recentlyhe said, they've yielded to a rising private sector. Zhang suggests it's time to launch a new round of state-run enterprise reform by selling small companies and introducing private investors for big ones, thus helping China maintain high economic growth.

    2015-06-01

    Full Text Available The paper provides an overview of the land reform in Russia's recent history. Analysis of land reform, which started in 1990, shows what actions and what logic led the land sector in the state in which it was at the finish line of the quarter-century reform marathon. The reform process was not linear, it highlighted the steps differing objectives and strategies to achieve them. Land reform is presented as a struggle of different political forces, which were reflected in the redistribution of functions between agencies in lobbying for appointment to senior positions promoted various commands. The authors conclude about the gradual displacement of state regulation of land relations, the deliberate destruction of the land management as a basis for the development of land resources.

    2016-05-01

    We model the labor market impact of the key provisions of the national and Massachusetts "mandate-based" health reforms: individual mandates, employer mandates, and subsidies. We characterize the compensating differential for employer-sponsored health insurance (ESHI) and the welfare impact of reform in terms of "sufficient statistics." We compare welfare under mandate-based reform to welfare in a counterfactual world where individuals do not value ESHI. Relying on the Massachusetts reform, we find that jobs with ESHI pay $2812 less annually, somewhat less than the cost of ESHI to employers. Accordingly, the deadweight loss of mandate-based health reform was approximately 8 percent of its potential size.

The NPTH program was designed to rear and release 1.4 million fall and 625,000 spring Chinook salmon. Construction of the central incubation and rearing facility NPTH and spring Chinook salmon acclimation facilities were completed in 2003 and the first full term NPTH releases occurred in 2004 (Brood Year 03). Monitoring and evaluation plans (Steward, 1996; Hesse and Cramer, 2000) were established to determine whether the Nez Perce Tribal Hatchery program is achieving its stated goals. The monitoring and evaluation action plan identifies the need for annual data collection and annual reporting. In addition, recurring 5-year program reviews will evaluate emerging trends and aid in the determination of the effectiveness of the NPTH program with recommendations to improve the program's implementation. This report covers the Migratory Year (MY) 2007 period of the NPTH Monitoring & Evaluation (M&E) program. There are three NPTH spring Chinook salmon treatment streams: Lolo Creek, Newsome Creek, and Meadow Creek. In 2007, Lolo Creek received 140,284 Brood Year (BY) 2006 acclimated pre-smolts at an average weight of 34.9 grams per fish, Newsome Creek received 77,317 BY 2006 acclimated pre-smolts at an average of 24

    Full Text Available Combined (steam and CO2 reforming is one of the methods to produce syngas for different applications. An energy requirement analysis of steam reforming to dry reforming with intermediate steps of steam reduction and equivalent CO2 addition to the feed fuel for syngas generation has been done to identify condition for optimum process operation. Thermodynamic equilibrium data for combined reforming was generated for temperature range of 400–1000°C at 1 bar pressure and combined oxidant (CO2 + H2O stream to propane (fuel ratio of 3, 6, and 9 by employing the Gibbs free energy minimization algorithm of HSC Chemistry software 5.1. Total energy requirement including preheating and reaction enthalpy calculations were done using the equilibrium product composition. Carbon and methane formation was significantly reduced in combined reforming than pure dry reforming, while the energy requirements were lower than pure steam reforming. Temperatures of minimum energy requirement were found in the data analysis of combined reforming which were optimum for the process.

    Full Text Available This paper highlights the most important institutional evolutions of Belgian federalism stemming from the implementation of the sixth state reform (2012-2014. This reform inter alia included a transfer of powers worth 20 billion euros from the federal level to the level of the federated states, a profound reform of the Senate, and a substantial increase in fiscal autonomy for the regions. This contribution critically analyses the current state of Belgian federalism. Although the sixth state reform realized important and long-awaited changes, further evolutions are to be expected. Since the Belgian state model has reached its limits with regard to complexity and creativity, politicians and academics should begin to reflect on the seventh state reform with the aim of increasing the transparency of the current Belgian institutional labyrinth.

    The main functions of the National Marine Fisheries Service (NMFS) Aquaculture Task biologists and contractual scientists involved in the 1978 homing studies were primarily a surveillance of fish physiology, disease, and relative survival during culture in marine net-pens, to determine if there were any unusual factors that might effect imprinting and homing behavior. The studies were conducted with little background knowledge of the implications of disease and physiology on imprinting and homing in salmonids. Hatcheries and stocks sampled are listed in Table 1. The health status of the stocks was quite variable as could be expected. The Dworshak and Wells Hatcheries steelhead suffered from some early stresses in seawater, probably osmoregulatory. The incidences of latent BKD in the Wells and Chelan Hatcheries steelhead and Kooskia Hatchery spring chinook salmon were extremely high, and how these will effect survival in the ocean is not known. Gill enzyme activity in the Dworshak and Chelan Hatcheries steelhead at release was low. Of the steelhead, survival in the Tucannon Hatchery stock will probably be the highest, with Dworshak Hatchery stock the lowest. The analyses conducted by the veterinary pathologist indicate that overall there was no evidence of serious pathological conditions that might be disastrous to any given stock, but at this time it is also difficult to interpret the results of certain types of clinical pathology that have either not been previously reported or extensively studied. For example, if the 77% incidence of basophillic granular organisms in the gills of the Carson coho salmon does represent an infestation of microsporidian protozoan parasites, is the intensity of infestation severe enough to cause irreparable damage that might affect survival? The results of the viral assays are questionable because the Rangen Laboratory is the only one that found evidence of viruses in these stocks (however, the veterinary pathologist did find evidence

The forces show distinct traits and adopt different ways in the process of affecting the schooling reform. In present China, the two forces of educational administration and social both have some aspects which are obstructive to the schooling reform. In order to advance the schooling reform, we have to improve the educational administration and guide the social needs for the education, so as to create a supporiive environment for schooling reform. What is more practical is that we should cultivate the force of advancing the schooling reform, based on the autonomous choice of the school which should be regarded as one of the agents of the reform.

    A bacterial disease was reported from gilthead sea bream (Sparus aurata) within a hatchery environment in Malta. Symptoms included complete erosion of tail, infection in the eye, mucous secretion and frequent mortality. A total of 540 strains were initially isolated in marine agar from different infected body parts and culture water sources. Subsequently 100 isolates were randomly selected, identified biochemically and all were found to be Vibrio harveyi-related organisms; finally from 100 isolates a total of 13 numbers were randomly selected and accurately identified as V. harveyi by 16S rRNA gene sequencing and species-specific PCR. Ribotyping of these strains with HindIII revealed total of six clusters. In vivo challenge study with representative isolates from each cluster proved two clusters each were highly pathogenic, moderately pathogenic and non-pathogenic. All 13 isolates were positive for hemolysin gene, a potential virulence factor. Further analysis revealed probably a single copy of this gene was encoded in all isolates, although not in the same locus in the genome. Although V. harveyi was reported to be an important pathogen for many aquatic organisms, to our knowledge this might be the first report of disease caused by V. harveyi and their systematic study in the sea bream hatchery from Malta.

    The Comparative Survival Study (CSS) was initiated in 1996 as a multi-year program of the fishery agencies and tribes to estimate survival rates over different life stages for spring and summer chinook (hereafter, chinook) produced in major hatcheries in the Snake River basin and from selected hatcheries in the lower Columbia River. Much of the information evaluated in the CSS is derived from fish tagged with Passive Integrated Transponder (PIT) tags. A comparison of survival rates of chinook marked in two different regions (which differ in the number of dams chinook have to migrate through) provides insight into the effects of the Snake/Columbia hydroelectric system (hydrosystem). The CSS also compares the smolt-to-adult survival rates (SARs) for Snake River chinook that were transported versus those that migrated in-river to below Bonneville Dam. Additional comparisons can be made within in-river experiences as well comparison between the different collector projects from which smolts are transported. CSS also compares these survival rates for wild Snake River spring and summer chinook. These comparisons generate information regarding the relative effects of the current management actions used to recover this listed species. Scientists and managers have recently emphasized the importance of delayed hydrosystem mortality to long-term management decisions. Delayed hydrosystem mortality may be related to the smolts experience in the Federal Columbia River Power System, and could occur for both smolts that migrate in-river and smolts that are transported. The CSS PIT tag information on in-river survival rates and smolt-to-adult survival rates (SARs) of transported and in-river fish are relevant to estimation of ''D'', which partially describes delayed hydrosystem mortality. The parameter D is the differential survival rate of transported fish relative to fish that migrate in-river, as measured from below Bonneville Dam to adults returning to Lower

    At the kokanee salmon hatcheries on Lake Roosevelt, constructed as partial mitigation for effects from Grand Coulee Dam, adult returns have been poor. The reason may be in the imprinting or in the smoltification. A study was initiated in 1992 to determine if there was a critical period for thyroxine induced alfactory imprinting in kokanee salmon; experiments were conducted on imprinting to morpholine and phenethyl alcohol. Other results showed that chemical imprinting coincided with elevated thyroxine levels in 1991 kokanee exposed to synthetic chemicals in 1992. In this report, imprinting experiments were repeated; results showed that imprinting occurred concomitant with elevated thyroxine levels in 1991 kokanee exposed to synthetic chemicals in 1992 and tested in 1994 as age 3 spawners. Imprinting also occurred at the same time as thyroxine peaks in 1992 kokanee exposed to synthetic chemicals in 1993 and tested as age 2 spawners. In both groups fish that had the highest whole body thyroxine content (swimup stage) also had the highest percentage of fish that were attracted to their exposure odor in behavioral tests. So, kokanee salmon imprinted to chemical cues during two sensitive periods during development, at the alevin/swimup and smolt stages. A field test was conducted in Lake Roosevelt on coded wire tagged fish. Smoltification experiments were conducted from 1992 to 1994. Recommendations are made for the Lake Roosevelt kokanee hatcheries.

    We investigated differences in the statistical power to assign parentage between an artificially propagated and wild salmon population. The propagated fish were derived from the wild population, and are used to supplement its abundance. Levels of genetic variation were similar between the propagated and wild groups at 11 microsatellite loci, and exclusion probabilities were >0.999999 for both groups. The ability to unambiguously identify a pair of parents for each sampled progeny was much lower than expected, however. Simulations demonstrated that the proportion of cases the most likely pair of parents were the true parents was lower for propagated parents than for wild parents. There was a clear relationship between parentage assignment ability and the degree of linkage disequilibrium, the estimated effective number of breeders that produced the parents, and the size of the largest family within the potential parents. If a stringent threshold for parentage assignment was used, estimates of relative fitness were biased downward for the propagated fish. The bias appeared to be largely eliminated by either fractionally assigning progeny among parents in proportion to their likelihood of parentage, or by assigning progeny to the most likely set of parents without using a statistical threshold. We used a DNA-based parentage analysis to measure the relative reproductive success of hatchery- and natural-origin spring Chinook salmon in the natural environment. Both male and female hatchery-origin fish produced far fewer juvenile progeny per parent when spawning naturally than did natural origin fish. Differences in age structure, spawning location, weight and run timing were responsible for some of the difference in fitness. Male size and age had a large influence on fitness, with larger and older males producing more offspring than smaller or younger individuals. Female size had a significant effect on fitness, but the effect was much smaller than the effect of size on

    1993-10-01

    From 1966 to 1968, Raymond estimated an average survival rate of 89% for yearling chinook salmon (Oncorhynchus tshawytscha) migrating from trap sites on the Salmon River to Ice Harbor Dam, which was then the uppermost dam on the Snake River. During the 1970s, the estimated survival rate declined as the proportion of hatchery fish increased and additional dams were constructed. Recent survival indices for yearling chinook salmon smolts in the Snake River Basin indicate that substantial mortalities are occurring en route to Lower Granite Dam, now the uppermost dam on the Snake River. Detection rates for wild and hatchery PIT-tagged smolts at Lower Granite Dam have been much lower than expected. However, for wild fish, there is considerable uncertainty whether overwinter mortality or smolt loss during migration is the primary cause for low survival. Efforts to rebuild these populations will have a better chance of success after the causes of mortality are identified and addressed. Information on the migrational characteristics and survival of wild fish are especially needed. The goal of this initial planning phase is to develop a research plan to outline potential investigations that will determine the timing, location, magnitude, and cause of smolt mortality above Lower Granite Dam.

    Concomitant sporadic high mortalities were reported in France in May 1994 among batches of hatchery-reared larval Pacific oysters Crassostrea gigas and European flat oysters Ostrea edulis in 2 hatcheries, and in June and July 1994 among batches of cultured spat of both species in a shellfish nursery. Histological observation showed the presence of cellular abnormalities in moribund animals. Transmission electron microscopy revealed the presence of herpes-like virus particles in infected larvae and spat of both oyster species. This is the first description of a herpes-like virus infection in larval O. edulis. Viruses observed in diseased larvae and spat of both species are similar with respect to ultrastructure and morphogenesis. They were detected simultaneously in C. gigas and O. edulis larvae and spat, indicating possible interspecific transmission. Moreover, these viruses are associated with high mortality rates in both oyster species. An electron microscopic examination revealed hemocytes with condensed chromatin and extensive perinuclear fragmentation of chromatin. These data suggest that herpes-like viruses infecting oysters may induce apoptosis in oyster hemocytes.

    This report details the smolt performance of natural and hatchery chinook salmon and steelhead from the Imnaha River to the Snake River and Columbia River dams during migration year 2000. Flow conditions in the Imnaha River and Snake River were appreciably lower during May and June in 2000, compared to historic levels at gauging stations, but flow conditions in the Imnaha and Snake River were above average during April. Overall, water conditions for the entire Columbia River were characterized by the Fish Passage Center as below normal levels. Spill occurred continuously at Lower Granite Dam (LGR), Little Goose Dam (LGO), and Lower Monumental Dam (LMO) from April 5, April 10, and April 4, respectively, to June 20, and encompassed the periods of migration of Imnaha River juvenile chinook salmon and steelhead, with a few exceptions. Outflow in the tailraces of LGR, LGO, and LMO decreased in May and June while temperatures increased. Chinook salmon and steelhead were captured using rotary screw traps at river kilometer (rkm) 74 and 7 during the fall from October 20 to November 24, 1999, and during the spring period from February 26 to June 15, 2000, at rkm 7. Spring trapping information was reported weekly to the Fish Passage Center's Smolt Monitoring Program. A portion of these fish were tagged weekly with passive integrated transponder (PIT) tags and were detected migrating past interrogation sites at Snake River and Columbia River dams. Survival of PIT tagged fish was estimated with the Survival Using Proportional Hazards model (SURPH model). Estimated survival of fall tagged natural chinook (with {+-} 95% confidence intervals in parenthesis) from the upper Imnaha (rkm 74) to LGR was 29.6% ({+-} 2.8 ). Natural chinook salmon tagged in the fall in the lower Imnaha River at rkm 7, which over wintered in the Snake River, had an estimated survival of 36.8% ({+-} 2.9%) to LGR. Spring tagged natural chinook salmon from the lower site had an estimated survival of 84

    Pathophysiology is a scientific discipline that studies the onset and progression of pathological conditions and diseases, and pathophysiology is one of the core courses in most preclinical medical curricula. In China, most medical schools house a Department of Pathophysiology, in contrast to medical schools in many developed countries. The staff in Chinese Departments of Pathophysiology generally consists of full-time instructors or lecturers who teach medical students. These lecturers are sometimes lacking in clinic knowledge and experiences. To overcome this, in recent years, we have been trying to bring new trends in teaching pathophysiology into our curriculum. Our purpose in writing this article was to share our experiences with our colleagues and peers worldwide in the hope that the insights we have gained in pathophysiology teaching will be of some value to educators who advocate teaching reform in medical schools.

    The Fukushima Daiichi NPP accident deeply questioned the bases of nuclear safety and nuclear safety regulation in Japan. It also resulted in a considerable loss of public confidence in the safety of nuclear power across the world. Although the accident was caused by natural phenomena, institutional and human factors also largely contributed to its devastating consequences, as shown by the Japanese Diet's and Government's investigation reports. 'Both regulators and licensees were held responsible and decided to fully reconsider the existing approaches to nuclear safety. Consequently, the regulatory system underwent extensive reform based on the lessons learned from the accident,' Yoshihiro Nakagome, the President of Japan Nuclear Energy Safety Organisation, an ETSON member TSO, explains.

    This paper provides an outlook of the electricity market reform in Greece which started in 2001 and is still developing slowly. This is related to the persisting dominance of the incumbent company and the specificities of the electricity sector of Greece which is heavily dependent on indigenous lignite firing generation, while being located in the periphery of the EU internal electricity and gas markets. Competition through enhancing electricity trade in the region is limited to date, as the establishment of an internal market in South East Europe also progresses slowly. Development of competition through gas-firing generation by new entrants has been the priority adopted by State and Regulator's policies. However, the gas supply market in Greece and in the region still lags behind. (author)

  13. Abortion law reform in Nepal.

    Upreti, Melissa

    2014-08-01

    Across four decades of political and social action, Nepal changed from a country strongly enforcing oppressive abortion restrictions, causing many poor women's long imprisonment and high rates of abortion-related maternal mortality, into a modern democracy with a liberal abortion law. The medical and public health communities supported women's rights activists in invoking legal principles of equality and non-discrimination as a basis for change. Legislative reform of the criminal ban in 2002 and the adoption of an Interim Constitution recognizing women's reproductive rights as fundamental rights in 2007 inspired the Supreme Court in 2009 to rule that denial of women's access to abortion services because of poverty violated their constitutional rights. The government must now provide services under criteria for access without charge, and services must be decentralized to promote equitable access. A strong legal foundation now exists for progress in social justice to broaden abortion access and reduce abortion stigma.

Excluding other factors may help us predict easier (but not more accurately future evolutions but as a scientific effort it is a bad practice. Much of the assumptions about technological change came from hasty generalizations. The changing nature of some collective actions, jobs in certain areas of the economy or organizations were considered as optimal (and necessary paths for the entire society (from individual to national levels. Public administration reforms are far from being a consequence of new technologies. Moreover public administration reforms do not embed ICTs and do not have a happy marriage with e-government.

    Full Text Available A great deal of comparative work on education reform is now being done, but this work often lacks a clearly articulated conceptual frame. This paper, based on a study of change in five jurisdictions in four countries, develops a model of reform based on four interactive elements - origins, adoption, implementation, and outcomes. Within each of these elements, questions and concepts from the relevant literature are developed with the intent of building a more comprehensive approach to the analysis of reform from political, organizational and educational perspectives.

    Ross, Johnathon S

    2009-05-01

    The 2008 presidential campaign season featured health care reform proposals. I discuss 3 approaches to health care reform and the tools for bringing about reform, such as insurance market reforms, tax credits, subsidies, individual and employer mandates, and public program expansions. I also discuss the politics of past and current health care reform efforts. Market-based reforms and mandates have been less successful than public program expansions at expanding coverage and controlling costs. New divisions among special interest groups increase the likelihood that reform efforts will succeed. Federal support for state efforts may be necessary to achieve national health care reform. History suggests that state-level success precedes national reform. History also suggests that an organized social movement for reform is necessary to overcome opposition from special interest groups.

    2013-01-01

    Full Text Available This article is a South African perspective of a Black African reflection on the publicity of Reformed faith. Whilst the notion of public theology is fairly new, the article argues, it is important to define the ‘public’ of the type of public theology to which Reformed faith and tradition could be linked. As a confessional tradition, Reformed faith is intrinsically public, the article demonstrates. The publicity of this tradition is however ambivalent and tainted. I attempt to show this by discussing two important tenets of the Reformed Tradition: sola scriptura and sola fide, within the festering wounds of Black African colonialism, apartheid and the hegemony of the neoliberal paradigm in the 21st century.

    1997-10-01

    This report reviews and analyzes the recent electricity reforms in Argentina, Australia, and the United Kingdom (UK) to illustrate how different models of privatization and reform have worked in practice. This report also analyzes the motivations of the U.S. companies who have invested in the electricity industries in these countries, which have become the largest targets of U.S. foreign investment in electricity. Two calculations of foreign investment are used. One is the foreign direct investment series produced by the U.S. Department of Commerce. The other is based on transactions in electric utilities of the three countries. The electricity reform and privatization experiences reviewed may offer some insight as to how the U.S. electricity industry might develop as a result of recent domestic reform efforts and deregulation at the state and national levels. 126 refs., 23 figs., 27 tabs.

    Full Text Available This article proposes a critical but non-systematic review of recent health care system reforms in developing countries. The literature reports mixed results as to whether reforms improve the financial protection of the poor or not. We discuss the reasons for these differences by comparing three representative countries: Mexico, Vietnam, and China. First, the design of the health care system reform, as well as the summary of its evaluation, is briefly described for each country. Then, the discussion is developed along two lines: policy design and evaluation methodology. The review suggests that i background differences, such as social development, poverty level, and population health should be considered when taking other countries as a model; ii although demand-side reforms can be improved, more attention should be paid to supply-side reforms; and iii the findings of empirical evaluation might be biased due to the evaluation design, the choice of outcome, data quality, and evaluation methodology, which should be borne in mind when designing health care system reforms.

    The Russian Government is pursuing a strategy of very high economic growth, with the objective of doubling gross domestic product in ten years. It recognises the central role the electricity sector has to play to achieve this target and has embarked on a highly ambitious program of electricity reform. If it is to succeed, the reform program will have to create market structures, market rules and a regulatory framework that will foster competitive wholesale and retail electricity markets. At the same time, it will have to deal with sensitive social issues related to tariff rebalancing and the removal of cross subsidies. Only competitive markets based on transparent prices that reflect costs can deliver the efficient, reliable and internationally competitive performance needed to meet the government's economic targets. Such markets are essential to attract new investment that will be required to ensure security of electricity supply after 2010. This book focuses on key aspects of the proposed reform that could have an important bearing on its success. It also raises concerns as to the pace of reform in related areas, such as the need for complementary reforms in the Russian natural gas sector. The IEA commends the Russian Government on its efforts to embrace this electricity reform - a key element critical to meeting the challenges ahead in terms of its economic growth and energy security. 17 figs., 10 tabs., 3 maps.

    Health information management policies usually address the use of paper records with little or no mention of electronic health records. Information Technology (IT) policies often ignore the health care business needs and operational use of the information stored in its systems. Representatives from the Telemedicine & Advanced Technology Research Center, TRICARE and Offices of the Surgeon General of each Military Service, collectively referred to as the Policies, Procedures and Practices Work Group (P3WG), examined military policies and regulations relating to computer-based information systems and medical records management. Using a system of templates and matrices created for the purpose, P3WG identified gaps and discrepancies in DoD and service compliance with the proposed Health Insurance Portability and Accountability Act (HIPAA) Security Standard. P3WG represents an unprecedented attempt to coordinate policy review and revision across all military health services and the Office of Health Affairs. This method of policy reform can identify where changes need to be made to integrate health management policy and IT policy in to an organizational policy that will enable compliance with HIPAA standards. The process models how large enterprises may coordinate policy revision and reform across broad organizational and work domains.

    Vance, J. M.; Hales, B. R.

    2010-12-01

    The increasing absorption of anthropogenic CO2 by the global ocean and concomitant decrease in pH will alter seawater carbonate chemistry in ways that may negatively impact calcifying organisms. In particular, the change in saturation state (Ω) of calcium carbonate minerals calcite and aragonite may be energetically unfavorable for shell formation while favoring shell dissolution. Eastern boundary upwelling systems may provide insights into how ecosystems respond to future conditions of ocean acidification when deep water with high dissolved inorganic carbon (DIC), low pH and low Ω is forced toward the surface. Mortality in commercial seed stock and reduced wild set of the oyster Crassostrea gigas in the northeast Pacific during 2005-2009 reinforced the need for understanding biological responses to acidified ocean water. In response, a long-term strategy to understand local carbonate chemistry dynamics, seasonal perturbations and the effects on development of calcifying bivalves was developed. At present, a time-series of pCO2 measurements was implemented in April 2010 in Netarts Bay, Oregon at Whiskey Creek Shellfish Hatchery (WCH). The intake sits at a depth of 0.5-8ft and water is pumped in at 100gpm. A line taken off the intake is run continuously through a thermosalinograph at approximately 1.5gpm into a showerhead style equilibrator in which the headspace is recirculated by aerating the water for enhanced gas exchange. CO2 in equilibrated air is analyzed by NDIR. Additionally two discrete samples of intake seawater were taken across tidal cycles weekly and analyzed for total CO2 (TCO2) according to the methods of Hales et al. (2004) and pCO2 for quality control. The pCO2 in the bay exhibits a diurnal cycle representative of daytime photosynthesis and nighttime respiration. However, the phasing and profiles of these cycles are dominated by tidal mixing and are affected by the introduction of high pCO2 water during upwelling events. Diurnal pCO2 during

    Full Text Available This study analyzes the implications of contemporary linguistic and cultural diversity concerning educational theory from three different perspectives: intercultural bilingual-education proposals; the demographical view in relation to language distribution and functionality; and the analysis of diversity within the framework of linguistic and cultural conflict. In recent searches for the meanings of diversity, sociolinguistic investigations have postulated that the consequences of the loss of diversity and its replacement by uniformity will be reflected in three important dimensions of social life: first, changes in communicative function and in cultural continuity; second, a more intense concentration of rationality or reflection on dominant linguistic and cultural models; and third, an intensification of the processes of diversification and specialization of subjects’ cultural skills pertaining to the needs of global projects. Multiculturalism and inequalities have erupted with such an impact on the sociopolitical platforms of global, national and ethnic projects that they have changed diversity and multidirectionality into fascinating but conflictive disclosures. Little by little these notions are giving support to a citizenship parameter for the society of the near future, when new national problems will arise, and new solutions, charged with participation and democratic meaning, will have to be devised. At the moment, the phenomena of interculturality, bilingualism and ethnodiversity are creating new parameters for the discussion of educational reform.

  19. Health Reform Requires Policy Capacity

    Directory of Open Access Journals (Sweden)

    Pierre-Gerlier Forest

    2015-05-01

    Full Text Available Among the many reasons that may limit the adoption of promising reform ideas, policy capacity is the least recognized. The concept itself is not widely understood. Although policy capacity is concerned with the gathering of information and the formulation of options for public action in the initial phases of policy consultation and development, it also touches on all stages of the policy process, from the strategic identification of a problem to the actual development of the policy, its formal adoption, its implementation, and even further, its evaluation and continuation or modification. Expertise in the form of policy advice is already widely available in and to public administrations, to well-established professional organizations like medical societies and, of course, to large private-sector organizations with commercial or financial interests in the health sector. We need more health actors to join the fray and move from their traditional position of advocacy to a fuller commitment to the development of policy capacity, with all that it entails in terms of leadership and social responsibility

    Steam reforming (SR) of ethanol, acetic acid, acetone, acetol, 1-propanol, and propanal has been investigated over Ni/MgAl2O4 at temperatures between 400 and 700 degrees C and at a steam-to-carbon-ratio (S/C) of 6. The yield of H-2 and conversion increased with temperature, while the yield of by-products...... decreased with temperature in the SR of the investigated compounds. The yield of H2 approached the thermodynamic limit at the highest temperatures investigated. No significant differences in conversion as a function of temperature among the different model compounds were observed. However, the product...... distribution depended on the model compound, and C-3-oxygenates produced a larger fraction of by-products compared to C-2-oxygenates. Temperatures of 600 degrees C or above were generally needed to minimize the fraction of by-products and obtain a syngas containing mainly CO, CO2, H-2, and H2O with only traces...

    2010-08-01

    The effects of a tropical cyclone on the distribution of hatchery-reared black-spot tuskfish Choerodon schoenleinii were examined using acoustic telemetry. Nine fish were released in Urasoko Bay, Ishigaki Island, Japan, in September 2006, and another nine were released in June to July 2007, before a cyclone's passing through the area in September 2007. Data for the fish released in 2006 were used as the cyclone-inexperienced group to compare their distribution pattern to that of the 2007 cyclone-experienced group. Both groups of fish were monitored for up to 150 days. Of the nine fish in each group, four (44%) and two (22%) were monitored for over 150 days in the cyclone-inexperienced and the cyclone-experienced groups, respectively. Three of the five fish that had settled in the monitoring area left the area within a few days of the cyclone event. To estimate the time of disappearance of the fish, maximum wind speed during a period of 7 days (indicating the occurrence and intensity of the tropical cyclone), fish size and release year were evaluated as explanatory variables using a Cox proportional hazards model with Akaike's information criterion. The best predictive model included the effect of maximum wind speed. One fish that left the monitoring area displayed movement patterns related to strong winds, suggesting that wind-associated strong currents swept the fish away. No relationships were found between the movement patterns of the other two fish and any physical environmental data. The daily detection periods of one of the two fish gradually decreased after the cyclone hit, and this fish eventually left the monitoring area within 3 days, suggesting that it shifted to a habitat outside the monitoring area. These results indicate that tropical cyclones have both direct and indirect effects on the distribution of hatchery-reared C. schoenleinii.

    2007-04-13

    This Project Final Report serves to document the project structure and technical results achieved during the 3-year project titled Advanced Autothermal Reformer for US Dept of Energy Office of Industrial Technology. The project was initiated in December 2001 and was completed March 2005. It was a joint effort between Sandia National Laboratories (Livermore, CA), Kellogg Brown & Root LLC (KBR) (Houston, TX) and Süd-Chemie (Louisville, KY). The purpose of the project was to develop an experimental capability that could be used to examine the propensity for soot production in an Autothermal Reformer (ATR) during the production of hydrogen-carbon monoxide synthesis gas intended for Gas-to-Liquids (GTL) applications including ammonia, methanol, and higher hydrocarbons. The project consisted of an initial phase that was focused on developing a laboratory-scale ATR capable of reproducing conditions very similar to a plant scale unit. Due to budget constraints this effort was stopped at the advanced design stages, yielding a careful and detailed design for such a system including ATR vessel design, design of ancillary feed and let down units as well as a PI&D for laboratory installation. The experimental effort was then focused on a series of measurements to evaluate rich, high-pressure burner behavior at pressures as high as 500 psi. The soot formation measurements were based on laser attenuation at a view port downstream of the burner. The results of these experiments and accompanying calculations show that soot formation is primarily dependent on oxidation stoichiometry. However, steam to carbon ratio was found to impact soot production as well as burner stability. The data also showed that raising the operating pressure while holding mass flow rates constant results in considerable soot formation at desirable feed ratios. Elementary reaction modeling designed to illuminate the role of CO2 in the burner feed showed that the conditions in the burner allow for the direct

    This report summarizes the Nez Perce Tribe (NPT) Department of Fisheries Resources Management (DFRM) results for the Lower Snake River Compensation Plan (LSRCP) Hatchery Evaluation studies and the Imnaha River Smolt Monitoring Program (SMP) for the 2007 smolt migration from the Imnaha River, Oregon. These studies are closely coordinated and provide information about juvenile natural and hatchery spring/summer Naco x (Chinook Salmon; Oncorhynchus tshawytscha) and Heeyey (steelhead; O. mykiss) biological characteristics, emigrant timing, survival, arrival timing and travel time to the Snake River dams and McNary Dam (MCD) on the Columbia River. These studies provide information on listed Naco x (Chinook salmon) and Heeyey (steelhead) for the Federal Columbia River Power System (FCRPS) Biological Opinion (NMFS 2000). The Lower Snake River Compensation Plan program's goal is to maintain a hatchery production program of 490,000 Naco x (Chinook salmon) and 330,000 Heeyey (steelhead) for annual release in the Imnaha River (Carmichael et al. 1998, Whitesel et al. 1998). These hatchery releases occur to compensate for fish losses due to the construction and operation of the four lower Snake River hydroelectric facilities. One of the aspects of the LSRCP hatchery evaluation studies in the Imnaha River is to determine natural and hatchery Naco x (Chinook salmon) and Heeyey (steelhead) smolt performance, emigration characteristics and survival (Kucera and Blenden 1998). A long term monitoring effort was established to document smolt emigrant timing and post release survival within the Imnaha River, estimate smolt survival downstream to McNary Dam, compare natural and hatchery smolt performance, and collect smolt-to-adult return information. This project collects information for, and is part of, a larger effort entitled Smolt Monitoring by Federal and Non-Federal Agencies (BPA Project No. 198712700). This larger project provides data on movement of smolts out of major

    Recent global experiences in electricity restructuring were examined with particular emphasis on how policy decisions have contributed to the current uncertainties for investment in electricity generation and transmission. California, Ontario, Alberta, and the United Kingdom were among the jurisdictions mentioned. It was noted that improved public policies that reduce uncertainties would encourage and manage industry restructuring while achieving improved economics and environmental objectives. Reform of economic regulations has been characterized by the following 3 trends: (1) liberalization, in which prices are determined by competitive markets, (2) state retrenchment, in which activities previously restricted by regulatory barriers are returned to the private sector, and (3) new regulatory design, in which new regulations are introduced to motivate public interest in a more competitive framework. It was noted that electricity is unlike other commodities. It cannot be economically stored and the market is characterized by volatile spot prices. The supply is not inexhaustible either. The electricity market has been more difficult to restructure than any other market that was used as a model for deregulation. No one jurisdiction has been completely successful in electricity restructuring, but each has its own merits and drawbacks. This document also discussed the impact that electricity restructuring will have on the climate change challenge and Canada's commitment under the Kyoto Protocol. When a jurisdiction moves to competitive power generation, generators look for the least expensive generation options, which are not necessarily the most environmentally desirable ones. It was emphasized that there is a need for long-term, integrated planning that addresses policy objectives for market regulation, climate change, and air quality. 38 refs., 1 tab., 1 fig.

    Full Text Available The present paper tries to assess the public administration reforms based on the opinions of public servants – the ones in charge with the actual implementation of the reforms. In November 2007 a mail survey was done in Romanian PA institutions. The opinions showed the necessity of the administrative reforms is accepted mainly as a request of the European Union. The way in which reforms were done is seen as a strenuous process, characterized by low coherence, with many changes of focus and done mainly through enacting new legislation over and over, which led to over-regulation. De-centralization (financial and managerial has still a long way to go, legislative improvement also (especially streamlining rules and procedures, citizens/community is not seen as a real partnership. More optimistic answers are regarding the functioning of local institutions (especially along the organizational culture dimension, which are seen as functioning very well in the context of reforms (a cautionary note should be made – loyalty or subjectivity may have lead to such answers.

  10. The agrarian reform, between memory and forgetfulness

    Full Text Available Although the Peruvian Agrarian Reform has been a mayor event for the peasant communities of Peru, especially in the Andes, it is barely evoked. It is the case of the community of Llanchu, located in the region of Cusco y in the Province of Calca, even if it has born thanks to the reform. In this paper we will analyse the way people refers to the agrarian reform. We will show that discourses about the past are socially controlled as any other kind of speech in that society. We will also discuss the way this past is engraved in the society and its territory. The ancient categories former to the reform are then still in use today even if they are expressed in new words. We will finally discuss the fact that the forgetfulness of the reform makes this community appear like a long-date one. The main question raised here is “what is supposed to be a peasant community today in the Peruvian Andes?” Is that so important to show a social unity and a historical continuity? This point is especially crucial today, as those populations entered in a process of ethnicization.

    The ongoing healthcare reform in China has a powerful spillover effect beyond the health sector and the borders of China. A successful completion of the Chinese reform will offer a new model for social justice development, shift the global economy toward sustainability and create a new hub for science and technology in medical and health science. However, reforming the healthcare system in the most populated country is a daunting task. China will not live up to its promise, and all the potentials may end with hype not hope if coherent national strategies are not constructed and state-of-the-art navigation is not achieved with staggering domestic and global challenges. The cost of failure will be immensely high, socioeconomic costs for Chinese and an opportunity cost for the world as a whole. A full appreciation of the global implications of China's healthcare reform is crucial in keeping China receptive toward good practices evidence-approved elsewhere and open minded to fulfill its international obligations. More critically, the appreciation yields constructive engagements from global community toward a joint development and global prosperity. The current report provides a multiple disciplinary assessment on the global implications of the healthcare reform in China.

    Program RealTime provided tracking and forecasting of the 2000 in season outmigration via the internet for stocks of wild PIT-tagged spring/summer chinook salmon. These stocks were ESUs from nineteen release sites above Lower Granite dam, including Bear Valley Creek, Big Creek, Camas Creek (new), Cape Horn Creek, Catherine Creek, Elk Creek, Herd Creek, Imnaha River, Johnson Creek (new), Lake Creek, Loon Creek, Lostine River, Marsh Creek, Minam River, East Fork Salmon River (new), South Fork Salmon River, Secesh River, Sulfur Creek and Valley Creek. Forecasts were also provided for two stocks of hatchery-reared PIT-tagged summer-run sockeye salmon, from Redfish Lake and Alturas Lake (new); for a subpopulation of the PIT-tagged wild Snake River fall subyearling chinook salmon; for all wild Snake River PIT-tagged spring/summer yearling chinook salmon (new) and steelhead trout (new)detected at Lower Granite Dam during the 2000 outmigration. The 2000 RealTime project began making forecasts for combined wild- and hatchery-reared runs-at-large of subyearling and yearling chinook, coho, and sockeye salmon, and steelhead trout migrating to Rock Island and McNary Dams on the mid-Columbia River and the mainstem Columbia River. Due to the new (in 1999-2000) Snake River basin hatchery protocol of releasing unmarked hatchery-reared fish, the RealTime forecasting project no longer makes run-timing forecasts for wild Snake River runs-at-large using FPC passage indices, as it has done for the previous three years (1997-1999). The season-wide measure of Program RealTime performance, the mean absolute difference (MAD) between in-season predictions and true (observed) passage percentiles, improved relative to previous years for nearly all stocks. The average season-wide MAD of all (nineteen) spring/summer yearling chinook salmon ESUs dropped from 5.7% in 1999 to 4.5% in 2000. The 2000 MAD for the hatchery-reared Redfish Lake sockeye salmon ESU was the lowest recorded, at 6.0%, down

    In view of artificially high urbanization rate of China and possible causes,survey and data analysis methods were used to discuss reform of household registration system,and path for promoting rural land system reform. Results show that it is required to eliminate bottlenecks of land system in the advance of new urbanization process. In line with land system bottlenecks of new urbanization,it is recommended to take following measures.( i) Promoting land right confirmation centered land system reform.( ii) Weakening rural land ownership and stressing land use right.( iii) Establishing urban and rural integrated land market and putting an end to low cost urbanization road.( iv) Realizing asset value of rural construction land and tackling the problem of insufficient construction land.( v) Reforming the land expropriation system and increasing the share of gain in land value to farmers.( vi) Implementing different land policies to promote coordinated development of regional social economy.( vii) Establishing land circulation access system to ensure unchanged land use purpose and high efficient use.

    Human space missions generate waste materials. A 70-kg crewmember creates a waste stream of 1 kg per day, and a four-person crew on a deep space habitat for a 400+ day mission would create over 1600 kg of waste. Converted into methane, the carbon could be used as a fuel for propulsion or power. The NASA Advanced Exploration Systems (AES) Logistics Reduction and Repurposing (LRR) project is investing in space resource utilization with an emphasis on repurposing logistics materials for useful purposes and has selected steam reforming among many different competitive processes as the preferred method for repurposing organic waste into methane. Already demonstrated at the relevant processing rate of 5.4 kg of waste per day, high temperature oxygenated steam consumes waste and produces carbon dioxide, carbon monoxide, and hydrogen which can then be converted into methane catalytically. However, the steam reforming process has not been studied in microgravity. Data are critically needed to understand the mechanisms that allow use of steam reforming in a reduced gravity environment. This paper reviews the relevant literature, identifies gravity-dependent mechanisms within the steam gasification process, and describes an innovative experiment to acquire the crucial kinetic information in a small-scale reactor specifically designed to operate within the requirements of a reduced gravity aircraft flight. The experiment will determine if the steam reformer process is mass-transport limited, and if so, what level of forced convection will be needed to obtain performance comparable to that in 1-g.

    Full Text Available Since the reformation and democratization movement in 1998, Indonesians have faced a chronic corruption problem. At the beginning of reformation era in 1998 to fight against corruption, the Indonesian government reforms the organization structure of the Indonesia Police to be an independent body separated from the Military organization. The police reforms begun in 1999 and got legal foundation with Act No. 2/2002. However, since fourteen years, the level of police reform has not yet succeed because of low community satisfaction on police service and the intense conflicts always occur whenever ACA investigates the case of corruptions conducted by police leaders. Three conflicts between police institution and ACA have taken placed. By using institutionalism approach, this research focus on the reform in police themselves are major actors on how reforms are organized and managed. This study is interpretative in nature gained only through social constructions such as language, consciousness, shared meanings, documents, tools, and other artefacts’. This finding revealed that this unsuccessful institutionalization process took place in a context of the main task of police for communicty service. Second, the study has demonstrated that three concepts from institutional theory as aforementioned provided vocabularies and insights to explain the phenomenon under study.

  18. The new architects of health care reform.

    Rising health care costs have been an issue for decades, yet federal-level health care reform hasn't happened. Support for reform, however, has changed. Purchasers fear that health care cost growth is becoming unaffordable. Research on costs and quality is questioning value. International comparisons rank the United States low on important health system performance measures. Yet it is not these factors but the unsustainable costs of Medicare and Medicaid that will narrow the window for health care stakeholders to shape policy. Unless the health care system is effectively reformed, sometime after the 2008 election, budget hawks and national security experts will eventually combine forces to cut health spending, ultimately determining health policy for the nation.

    The main contributions of this study are to conduct a comparative thermodynamic analysis of methane reforming reactions and to asses the influence of key operational variables on chemical equilibrium using an in-house code, developed in the open-source software Scilab{sup c} INRIA-ENPC (www.scilab.org). Equilibrium compositions are calculated by two distinct methods: evaluation of equilibrium constants and Lagrange multipliers. Both methods result in systems of non-linear algebraic equations, solved numerically using the Scilab function 'fsolve'. Comparison between experimental and simulated equilibrium data, published in the literature, was used to validate the simulated results. Effects of temperature, pressure, initial H{sub 2}O/CH{sub 4} ratio (steam reforming), initial CH{sub 4}:CO{sub 2}:N{sub 2} ratio (dry reforming) and initial O{sub 2}/CH{sub 4} ratio (partial oxidation) on the reaction products were evaluated.
