    Amezcua-Martinez, Felipe; Bellgraph, Brian J.

    2014-09-14

    The contributed papers in this book provide research undertaken in estuarine systems of Mexico and Central America that aim to provide a scientific basis for proper estuarine management. The book is divided in three parts that cover topics associated with fisheries management and regulations: physicochemical studies, ecological studies and socioeconomic studies. This introduction outlines the contents of this book in relation to the management of coastal ecosystems, which have a high socioeconomic importance for a large proportion of the population in this area of the world. Rather than be a definitive suite of papers for the regulation of these habitats, the goal of this book is to outline the urgent need to continue research of threatened coastal ecosystems of Mexico and Central America.

    Full Text Available The aims of this study is to report some characteristics of fishing trips, effort, catches, fishing areas and bycatch through observations on board and logbooks. 85% of sets were in the first 574 Km of distance from the coast (309 nautical miles. Farthest set was located at 1320 Km (712 nautical miles. A total of 382000 hooks were used to catch Mahi mahi, in 224 sets and 29 fishing trips, 94.6% of catch was Mahi mahi, 2.7% blue shark (Prionace glauca y 1,3% mako shark (Isurus oxyrinchus. Also, 103790 hooks were used to catch sharks, in 109 sets y 12 trips, 81.9% of catch was blue sharks and 16.8% mako sharks. Catch per Unit of Effort (CPUE for Mahi mahi shows significative difference among seasons; with a peak from November to January. CPUE for shark shows significative difference among seasons, with peaks in September and October. The Green turtle Chelonia mydas agassizii was the most caugth species and two of three were juveniles. All Loggerhead turtles, Caretta caretta, caught were juveniles. A petrel is reported as bycatch and, probably, mammal bycatch is scarce. Considering the huge effort of this fishery, it is important to monitor it and establish management actions.

  5. Cooperation between scientists, NGOs and industry in support of sustainable fisheries: the South African hake Merluccius spp. trawl fishery experience.

    This paper examines the increasingly close interaction between natural and social scientists, non-governmental organizations (NGO) and industry, in pursuit of responsible ecosystem-based management of fisheries. South Africa has committed to implementing an ecosystem approach to fisheries management. Management advice stems from multi-stakeholder representation on government-led scientific and management working groups. In the hake Merluccius capensis and Merluccius paradoxus fishery, the primary management measure is an annual total allowable catch (TAC), the level of which is calculated using a management procedure (MP) that is revised approximately every 4 years. Revision of the MP is a consultative process involving most stakeholders, and is based on simulation modelling of projected probable scenarios of resource and fishery dynamics under various management options. NGOs, such as the Worldwide Fund for Nature in South Africa (WWF-SA), have played an important role in influencing consumers, the fishing industry and government to develop responsible fishing practices that minimize damage to marine ecosystems. Cooperation between industry, government and scientists has helped to improve sustainability and facilitated the meeting of market-based incentives for more responsible fisheries. Research includes ecosystem modelling, spatial analysis and ecosystem risk assessment with increasing research focus on social and economic aspects of the fishery. A four-year cooperative experiment to quantify the effect of trawling on benthic community structure is being planned. The food requirements of top predators still need to be included in the TAC-setting formulae and more social and economic research is needed. This paper also demonstrates how NGO initiatives such as Marine Stewardship Council certification and the Southern African Sustainable Seafood Initiative, a traffic light system of classifying seafood for consumers, have contributed to responsible fishing

    Full Text Available Fisheries has recently been very exploited area in the Croatian media, either regarding the EU accession negotiations or regarding the interrelationships of the involved parties within Croatia. Iceland is one of the strongest fishery nations in the world that passed through some heavy struggles to protect its fishery grounds (so called “fishery or cod wars”. Therefore its experience in fisheries can be useful when creating Croatian fishery policy. So, the aim of this article is to present the Statement on Responsible Fisheries in Iceland signed by all the parties involved in the Icelandic fishery industry.

  9. Liberalisation Reform, 'Neo-centralism', and Black Market: The Political Diseconomy of Lake Nasser Fishery Development

    Directory of Open Access Journals (Sweden)

    Christophe Béné

    2008-10-01

    Full Text Available Despite its relatively modest importance, and the current difficulties faced by the government in implementing liberalisation in the rest of the country, the Egyptian governement decided to embark on a reform of the Lake Nasser fishery in the early 2000s. The objective of this article is to analyse the evolution of this reform from a political economy perspective. The paper looks retrospectively at the general context of the reform, describes the different institutional and economic changes that have resulted from its realisation, identifies how the distribution of power between the different actors has altered the course of its implementation, and finally assesses the outcomes of the reform. The analysis shows that, while some major institutional changes have taken place, those changes have had little to do with a 'liberalisation' as conventionally understood in neo-classical literature. Instead, the new status quo turns out to be one where the central government and its different parastatal agencies have managed to maintain their existing advantages. The failure to reform more thoroughly the system also led fishers and fish traders to engage in a large-scale black market activity in which a substantial amount of fish is smuggled through unofficial trade channels.

  10. Add-on conservation benefits of marine territorial user rights fishery policies in central Chile.

    Gelcich, Stefan; Godoy, Natalio; Prado, Luis; Castilla, Juan Carlos

    2008-01-01

    To combine the rational use of marine benthic resources and economic development of small-scale fishers, Chile passed legislation in 1991 establishing a comanagement policy that grants exclusive territorial user rights for fisheries (TURFs) to artisanal fisher organizations in well-defined inshore coastal areas, known as Management and Exploitation Areas for Benthic Resources (MEABRs). In general the policy has been proclaimed a management and economic success because benthic resource abundances have increased inside MEABRs in comparison with open-access areas. However, there is a lack of studies assessing the impact of this management policy on nontargeted subtidal species and community assemblages and the policy's implications for biodiversity and conservation. This study starts to fill this gap and links the allocation of TURFs for benthic resources with add-on conservation benefits for species that are not directly linked with the fishery policy. Comparative subtidal surveys inside vs. outside MEABRs were used to assess the effects of three MEABRs on managed targeted benthic species, biodiversity (species richness), and community assemblages in central Chile. Surveys focused exclusively on subtidal kelp forest habitats dominated by Lessonia trabeculata, spanning 4-12 m in depth and with similar levels of habitat complexity. The study comprised: (1) quantification of kelp forest complexity, (2) understory survey of sessile species, (3) quantification of conspicuous benthic macroinvertebrates, including those under management, and (4) quantification of reef-fish species inside the kelp habitat. Results showed population enhancement of target-managed invertebrates inside MEABRs. Moreover, reef-fish species were significantly more diverse and abundant inside MEABRs, and community assemblages of nontarget benthic invertebrates and reef fish were significantly different inside vs. outside MEABRs. The comanagement of inshore benthic resources in Chile, through MEABRs

    Full Text Available This paper reviews some major challenges experienced in the implementation of fisheries co-management initiatives in response to governance reforms being advocated in various countries. Lessons are drawn from Malawi's experiences on the implementation of co-management arrangements. Appropriate policy and legal frameworks that govern management of the fisheries resources in decentralised structures should be formulated as attributes to community empowerment. Defining clear objectives and incentives for fisheries co-management becomes a challenge where appropriation of the commons is for survival especially in areas where poverty is persistent. There are limited resilient co-management institutions due to unclear definition of roles for various stakeholders and limited participation of civil society groups in the management of the commons as part of the governance system. Traditional institutions play a role either in support of or against sustainable resource management is response to inducements of various forms especially from migrants which challenges exclusion of non-members from appropriating the commons. The principles of good governance that include participation and accountability of the representative committees are limited in some areas. The initiation process as to whether the co-management was introduced by government or by the user community affects resilience of the co-management institutions. However, adoption of broad-based co-management regimes with various empowered stakeholders including the civil society, non-governmental organisations and government agencies are a positive step towards achievement of a sustainable fish resource management.

    2010-01-01

    How multiple stressors influence fish stock dynamics is a crucial question in ecology in general and in fisheries science in particular. Using time-series covering a 30 yr period, we show that the body growth of the central Baltic Sea herring Clupea harengus, both in terms of condition and weight-at-age (WAA), has shifted from being mainly driven by hydro-climatic forces to an inter-specific density-dependent control. The shift in the mechanisms of regulation of herring growth is triggered by...

    Karen A. Villarta

    2010-06-01

    Full Text Available This study documents the fishery of the short-necked clam Paphia undulata in coastal waters of southern Negros Occidental. Catch and effort estimates were determined based on daily records of compressor divers gathered between February-July 2008 in Himamaylan City and July 2008-May 2009 in the town of Hinigaran. Fishing and marketing practices in both areas were also documented and population biology information noted.Compared to earlier conditions, present fishing patterns show a worsened stage of overexploitation primarily characterized by collection of predominantly small and immature (mostly <45 mm shell lengths sizes. Intensity/duration and location of fishing also varied due to both abundance and demand factors.The difference in sizes of clams and the varying fishing durations in each area suggest a non-uniform pattern of settlement resulting most likely from differential larval recruitment, the likely factors causing the local boom and bust fishery. The larger and long term extent of the effect of these factors can only be further investigated by parallel 2-3 year fishery-dependent and -independent surveys

    Full Text Available Dolphin interactions with fishermen have increased significantly and pose potential risks to the boto, Inia geoffrensis (Blainville, 1817, and the tucuxi, Sotalia fluviatilis (Gervais & Deville, 1853. The main objective of the present paper was to describe the existing conflicts between river dolphins and fishermen in the municipality of Manacapuru region. Sixteen fishermen were interviewed in Manacapuru, state of Amazonas, Brazil who described a situation of ongoing conflict that may be unsustainable. Two merchants from Manacapuru made unconfirmed reports on a boto carcass trade. Data collection for this study occurred between April 20th and April 25th, 2009, but the first author had been conducting research on river dolphins and fisheries in Manacapuru and nearby cities since the beginning of 2008, in order to gain the trust of the fishermen interviewed. The hunting and deliberate killing of the species is probably more threatening to botos than their incidental capture in fishing gears in the Manacapuru region. This practice may result from the fact that dolphins are prone to damaging fishing equipment, and stealing (and possibly damaging fish from the nets. They are portrayed negatively in numerous myths and superstitions of traditional Amazonian folklore, making them extremely undesired or even hated, seen as pests, and used in the piracatinga, Calophysus macropterus (Lichtenstein, 1819 fishery as bait. For tucuxis, incidental capture still represents the major threat to their conservation in the region evaluated here.

    The reported annual yield from inland capture fisheries in 2008 was over 10 million tonnes, although real catches are probably considerably higher than this. Inland fisheries are extremely complex, and in many cases poorly understood. The numerous water bodies and small rivers are inhabited by a wide range of species and several types of fisher community with diversified livelihood strategies for whom inland fisheries are extremely important. Many drivers affect the fisheries, including internal fisheries management practices. There are also many drivers from outside the fishery that influence the state and functioning of the environment as well as the social and economic framework within which the fishery is pursued. The drivers affecting the various types of inland water, rivers, lakes, reservoirs and wetlands may differ, particularly with regard to ecosystem function. Many of these depend on land-use practices and demand for water which conflict with the sustainability of the fishery. Climate change is also exacerbating many of these factors. The future of inland fisheries varies between continents. In Asia and Africa the resources are very intensely exploited and there is probably little room for expansion; it is here that resources are most at risk. Inland fisheries are less heavily exploited in South and Central America, and in the North and South temperate zones inland fisheries are mostly oriented to recreation rather than food production.

  18. Central Equatorial Pacific Experiment (CEPEX). Design document

    Energy Technology Data Exchange (ETDEWEB)

    1993-04-01

    The Earth`s climate has varied significantly in the past, yet climate records reveal that in the tropics, sea surface temperatures seem to have been remarkably stable, varying by less than a few degrees Celsius over geologic time. Today, the large warm pool of the western Pacific shows similar characteristics. Its surface temperature always exceeds 27{degree}C, but never 31{degree}C. Heightened interest in this observation has been stimulated by questions of global climate change and the exploration of stabilizing climate feedback processes. Efforts to understand the observed weak sensitivity of tropical sea surface temperatures to climate forcing has led to a number of competing ideas about the nature of this apparent thermostat. Although there remains disagreement on the processes that regulate tropical sea surface temperature, most agree that further progress in resolving these differences requires comprehensive field observations of three-dimensional water vapor concentrations, solar and infrared radiative fluxes, surface fluxes of heat and water vapor, and cloud microphysical properties. This document describes the Central Equatorial Pacific Experiment (CEPEX) plan to collect such observations over the central equatorial Pacific Ocean during March of 1993.

    An impact assessment of a Fishery Observing System (FOS) network in the Adriatic Sea was carried out with an ocean circulation model fully-coupled with a data assimilation system. The FOS data are single point vertical values of temperature collected in 2007. In this study, we used the Observing System Experiment (OSE) and Observing System Simulation Experiment (OSSE) methodologies to estimate the impact of different FOS design and sensors implementation. OSEs were conducted to evaluate real observations and they show that the FOS network improves the analysis significantly, especially during the stratification season. Root mean square (RMS) of temperature errors are reduced by about 44% and 36% in the upper and lower layers respectively. We also demonstrated that a similar impact can be obtained with a reduced number of vessels if the spatial coverage of the data points does not change significantly. In the OSSE, the impact of the implementation of a CTD (conductivity-temperature-depth) sensor in place of the existing temperature sensor was tested with identical twin approaches between January and April 2007. The results imply that the assimilation of salinity does not improve the analysis significantly during the winter and spring seasons.

  3. Fishing mortality in North Carolina's southern flounder fishery: direct estimates of instantaneous fishing mortality from a tag return experiment

    Science.gov (United States)

    Smith, William E.; Scharf, Frederick S.; Hightower, Joseph E.

    2009-01-01

    Estimation of harvest rates is often a critical component of fishery stock assessment and management. These assessments are often based on catch-at-age data sets generated over many years, but estimates of instantaneous fishing mortality (F) can also be obtained from a shorter-term tag return study. We conducted a 2-year tag return experiment to generate direct estimates of F for southern flounder Paralichthys lethostigma in a North Carolina estuary. The southern flounder supports lucrative commercial and recreational fisheries within the state and has experienced heavy fishing pressure for more than a decade. During 2005 and 2006, fish were captured and tagged with the assistance of commercial harvesters in the New River estuary. Tag returns were used to generate monthly estimates of F, which demonstrated a clear seasonal pattern that was consistent between years. Several important assumptions of the tag return model were accounted for through the use of double-tagged individuals, the distribution of both high- and standard-reward tags, and the completion of an independent controlled experiment to evaluate mortality related to tagging. Annual estimates of F exceeded the short-term management target in both years. Residual patterns suggest that the estimates may actually have been biased low, possibly due to delayed mixing of tagged fish. Thus, despite recently amended fishery regulations, F in the North Carolina southern flounder gill-net fishery still has the potential to greatly exceed targeted levels, which may delay stock recovery. Tag return studies can provide reliable (and nearly real-time) information about F and natural mortality as long as the experimental design addresses specific assumptions related to tagging-induced mortality, tag shedding, and nonreporting of tags.

    Madsen, Niels; Tschernij, Vesa; Holst, René

    2010-01-01

    Due to declining cod (Gadus morhua) stocks, the Baltic Sea was one of the first areas regulated by the European Communities where selective escape windows were implemented to improve the exploitation pattern. Increasing discard rates and the potential for a significant increase of the spawning...... stock and the yield of the fishery are important reasons to further improve the selectivity of the fishery and to asses the potential next step in this process. In this study, we tested three relatively different design concepts, in the Baltic cod pelagic trawl fishery, that are relevant to past...... or present legislation and that were developed to meet requirements of increased selectivity performance. A standard nominal 135 mm diamond mesh codend, a codend with two nominal 125 mm bottom windows, and a codend with a nominal 125 mm nominal top window were tested using the covered codend method.

  8. Exploitation rates of two benthic resources across management regimes in central Chile: Evidence of illegal fishing in artisanal fisheries operating in open access areas.

    Science.gov (United States)

    2017-01-01

    There is an urgent need to quantify the impacts of artisanal fisheries and define management practices that allow for the recovery and conservation of exploited stocks. The extent of illegal catch is particularly critical as a driver of overexploitation in artisanal fisheries. However, the lack of data at proper spatial scales limits the evaluation of illegal fishing and effectiveness of management practices. We used a catch curve analysis to estimate total instantaneous mortality as a proxy of fishing pressure in the artisanal benthic fishery in central Chile. We compared the patterns of total mortality in fishing grounds under the well-studied territorial use rights for fisheries system (TURF) immersed in a landscape of open access areas (OAA; no access restriction), and from these patterns determined the extent of illegal fishing in open access areas focusing on the two most frequently extracted resources: locos (Concholepas concholepas) and keyhole limpets (Fissurella spp.). The beauty of this seascape is the presence of the no-take (NT) area of Las Cruces as control (no fishing), allowing us to estimate natural mortality. Loco exploitation is banned in OAAs. However, loco mortality in OAAs was 92% higher than in the NT, and 42% higher than in TURFs. Keyhole limpet mortality was similar between TURFs and the NT, but doubled in OAAs. We also found strong differences in mortality among fishing grounds with the same level of protection (i.e. TURFs), and over time. Our results highlight (a) the high level of illegal fishing that may occur in artisanal fisheries under traditional management regimes, and (b) that TURFs can be effective to reduce fishing mortality. However, large variability among TURFs suggests the need for a deeper understanding of the drivers of success of TURFs.

  9. Challenges in merging fisheries research and management: The Upper Mississippi River experience

    Science.gov (United States)

    Garvey, J.; Ickes, B.; Zigler, S.

    2010-01-01

    The Upper Mississippi River System (UMRS) is a geographically diverse basin extending 10?? north temperate latitude that has produced fishes for humans for millennia. During European colonization through the present, the UMRS has been modified to meet multiple demands such as navigation and flood control. Invasive species, notably the common carp, have dominated fisheries in both positive and negative ways. Through time, environmental decline plus reduced economic incentives have degraded opportunities for fishery production. A renewed focus on fisheries in the UMRS may be dawning. Commercial harvest and corresponding economic value of native and non-native species along the river corridor fluctuates but appears to be increasing. Recreational use will depend on access and societal perceptions of the river. Interactions (e. g., disease and invasive species transmission) among fish assemblages within the UMRS, the Great Lakes, and other lakes and rivers are rising. Data collection for fisheries has varied in intensity and contiguousness through time, although resources for research and management may be growing. As fisheries production likely relies on the interconnectivity of fish populations and associated ecosystem processes among river reaches (e. g., between the pooled and unpooled UMRS), species-level processes such as genetics, life-history interactions, and migratory behavior need to be placed in the context of broad ecosystem- and landscape-scale restoration. Formal communication among a diverse group of researchers, managers, and public stakeholders crossing geographic and disciplinary boundaries is necessary through peer-reviewed publications, moderated interactions, and the embrace of emerging information technologies. ??

    This paper examines why market and government institutions failed to prevent over fishing in the Southern Gulf snow crab fishery, whereas non-market institutions succeeded. A general conclusion is that the institutional environment in which economic behaviour must be coordinated for successful fishe

  15. Comparative analysis of depth distribution for seventeen large pelagic fish species captured in a longline fishery in the central-eastern Pacific Ocean

    2012-02-01

    Full Text Available The objective of this study was to estimate depth distribution of pelagic species captured in a longline fishery and to evaluate the difference in depth distribution among species. We estimated depth distribution for 17 frequently captured species based on a Chinese longline fishing trip targeting bigeye tuna (Thunnus obesus in the central-eastern Pacific Ocean in February-November 2006. The depth distributions of 13 bycatch species were significantly different from that of bigeye tuna. Although most of the bycatch species were found to be distributed in water depths shallower than bigeye tuna (i.e. increasing hook depths can decrease catch rates of these species, the rates of catch rates declined with increasing hook depths may be different. The depth distributions were found to be not significantly different between genders for 7 species. There was no significant correlation between fish sizes and capture depths. The information derived from this study can play an important role in reducing bycatch in pelagic tuna longline fisheries in the central-eastern Pacific Ocean.

  16. Impacts of the Snake River drawdown experiment on fisheries resources in Little Goose and Lower Granite Reservoirs, 1992

    1992-09-01

    In March 1992, the US Army Corps of Engineers initiated a test to help evaluate physical and environmental impacts resulting from the proposed future drawdown of Snake River reservoirs. Drawdown would reduce water levels in Snake River reservoirs and is being proposed as a solution to decrease the time it takes for salmon and steelhead smolts to migrate to the ocean. The Pacific Northwest Laboratory evaluated impacts to specific fisheries resources during the drawdown experiment by surveying Lower Granite Reservoir to determine if fall chinook salmon (Oncorhynchus tshawytscha) spawning areas and steelhead (0. mykiss) access to tributary creeks were affected. In addition, shoreline areas of Little Goose Reservoir were monitored to evaluate the suitability of these areas for spawning by fall chinook salmon. Relative abundance of fish species in nearshore areas was also determined during the drawdown, and stranded resident fish and other aquatic organisms were observed.

  17. Field experiments to improve the efficacy of gargoor (fish trap) fishery in Kuwait's waters

    Fish traps were investigated to understand the effects of season, bait type, trap size, and trap soak time on catch rates, catch composition, and trap loss rates from March 2004 to September 2005, to improve the performance and management of Kuwait's gargoor (cage style fish trap) fishery, which used to be the nation's most important one in terms of value and landings volume. Catch rates were the highest in April/May (5-8 kg/trap haul) and again in December (7 kg/trap haul). Bait type and trap size also affected catch rates and species composition. Of the seven baits tested, the best catch rates, >5 kg/trap haul, occurred with cuttlefish ( Sepia pharaonis), but wolf-herring ( Chirocentrus dorab) and mullet ( Liza klunzingeri) also produced good results (4-5 kg/trap haul). Within the five tested sizes, the two largest-sized traps captured more fish and larger size fish. Analysis of variance (ANOVA) showed significant differences of catch rate among traps with different baits as well as among traps of different sizes. Duncan test further revealed these differences between two specific baits and sizes. Cluster Analysis of species composition showed more differences among different baits than among different trap sizes. Longer soak times did not result in larger catch rates, but increased trap loss. About 10-day soak time resulted in trap loss 7%, while 40-day soak time could result in a loss of around 20%. Consequently, it is recommended that the gargoor be checked every 10 or fewer days. The average overall catch rate during the study period was lower than that of 1980s (4.5 vs. 5.8 kg/trap haul), indicating a possible decline of fish abundance in Kuwait's waters. It is recommended that the number of gargoor fishing boats and gargoors from each boat should be limited to allow stock rehabilitation.

    Although inland and marine environments, their fisheries, fishery managers, and the realm-specific management approaches are often different, there are a surprising number of similarities that frequently go unrecognized. We contend that there is much to be gained by greater cross-fertilization and exchange of ideas and strategies between realms and the people who manage them. The purpose of this paper is to provide examples of the potential or demonstrated benefits of working across aquatic boundaries for enhanced sustainable management of the world’s fisheries resources. Examples include the need to (1) engage in habitat management and protection as the foundation for fisheries, (2) rethink institutional arrangements and management for open-access fisheries systems, (3) establish “reference points” and harvest control rules, (4) engage in integrated management approaches, (5) reap conservation benefits from the link to fish as food, and (6) reframe conservation and management of fish to better engage the public and industry. Cross-fertilization and knowledge transfer between realms could be realized using environment-independent curricula and symposia, joint scientific advisory councils for management, integrated development projects, and cross-realm policy dialogue. Given the interdependence of marine and inland fisheries, promoting discussion between the realms has the potential to promote meaningful advances in managing global fisheries.

  20. Food web and fish stock changes in central Chile: comparing the roles of jumbo squid (Dosidicus gigas) predation, the environment, and fisheries

    Neira, Sergio; Arancibia, Hugo

    2013-10-01

    We analyzed recent food web and fish stock changes in the central Chile marine ecosystem, comparing the roles of jumbo squid (Dosidicus gigas) as predator, the environment, and fishing. To accomplish this we used food web modeling and the Ecopath with Ecosim software (EwE). The principal fish stocks have experienced wide decadal fluctuations in the past 30 years, including stock collapses of horse mackerel (Trachurus murphyi) and hake (Merluccius gayi), and there was a large influx of jumbo squid during the mid-2000s. We used two EwE models representing the food web off central Chile to test the hypothesis that predation by jumbo squid has been significant in explaining the dynamics of the main fishing resources and other species in the study area. Results indicate that predation by jumbo squid on fish stocks is lower than that of other predators (e.g. hake) and the fishery. Long-term fluctuations (1978-2004) in the biomass of the main fish stocks (as well as other components of the food web) seem to be related to fishing and to variation in primary production, rather than to predation by jumbo squid alone. Jumbo squid seems to play a role as predator rather than prey in the system, but its impacts are low when compared with the impacts of other predators and fishing. Therefore, we conclude that jumbo squid predation on its prey was not the primary force behind the collapse of important fish stocks off central Chile. Future efforts should be directed to better understanding factors that trigger sudden increases in jumbo squid abundance off central Chile, as well as modeling its trophic impacts.

    Tracheal stenosis is a serious, life-threatening disease with an increasing tendency. The number of complicated tracheal lesions, where resection and anastomosis can not be performed, still increases and the situation requires solution by endoprosthesis. Consequent the management of such complicated obstructive tracheal lesions is individual and time-consuming. The main objective of this study is to review the single institution experience with central airways stenosis treatment and to define the role of endotracheal stenting in tracheal reconstruction surgery. This study presents the retrospective analysis of tracheal stenosis reconstruction by means of our own modification of Montgomery T-tube. (Tab. 3, Fig. 3, Ref. 12.)

    The jaraquis (Semaprochilodus spp.) are the most abundant group in the fishing landing in Manaus. However, just command and control management strategies have been used by the fishery governmental agency in the region without the power to enforce centralized decisions. The fishermen and their culture represent a source of information on dynamics of the resources and aquatic environments, fundamental in making possible the co-management of the fishing resources. The present study aims to contribute to management through identification of common information available in scientific and traditional knowledge about the jaraquis' bio-ecology. There were 57 semi-structured interviews recorded with fishermen of Manaus and rural areas of Manacapuru in 2002 concerning biological and ecological aspects. Similarity was observed between scientific and traditional knowledge in the following items: size of first sexual maturation, spawning type, parental care, trophic relationships and migratory behavior, as well as in some aspects of the mortality and growth of the species. However, there was less ethnoicthyological information on fecundity and the determination of the age and growth of adult fish. Common information would be used preferably by agencies to start an effective and technical dialogue with commercial and riverine fishermen to design management plans in a decentralized strategy.

    The STAR experiment at the Relativistic Heavy Ion Collider (RHIC) performs studies of diffractive processes with the focus on the exclusive production of particles in central range of rapidity. In 2015 STAR collected 18 pb$^{-1}$ of data in polarized proton+proton collisions at $\\sqrt{s}$=200 GeV to measure Central Exclusive Production (CEP) process $pp\\to pXp$ through Double Pomeron Exchange (DPE) mechanism. The intact protons moving inside the RHIC beampipe after the collision were measured in silicon strip detectors (SSD), which were placed in the Roman Pot vessels. This enables full control over interaction kinematics and verification of the exclusivity of the reaction by measuring the total (missing) transverse momenta of all final state particles: the central diffractive system in the Time Projection Chamber (TPC) and the forward protons in the Roman Pots. With the use of ionization energy loss in the TPC, d$E$/d$x$, it was possible to discriminate various production channels in $pp\\to pXp$ reaction. Th...

    The well-drained sandy soil in the Wisconsin Central Sands is ideal for growing potatoes, corn, and other vegetables. A shallow sand and gravel aquifer provides abundant water for agricultural irrigation but also supplies critical base flow to cold-water trout streams. These needs compete with one another, and stakeholders from various perspectives are collaborating to seek solutions. Stakeholders were engaged in providing and verifying data to guide construction of a groundwater flow model which was used with linear and sequential linear programming to evaluate optimal tradeoffs between agricultural pumping and ecologically based minimum base flow values. The connection between individual irrigation wells as well as industrial and municipal supply and streamflow depletion can be evaluated using the model. Rather than addressing 1000s of wells individually, a variety of well management groups were established through k-means clustering. These groups are based on location, potential impact, water-use categories, depletion potential, and other factors. Through optimization, pumping rates were reduced to attain mandated minimum base flows. This formalization enables exploration of possible solutions for the stakeholders, and provides a tool which is transparent and forms a basis for discussion and negotiation.

    Full Text Available Diagnostic laboratory services in Alberta have been dramatically restructured over the past five years. In 1994, Alberta Health embarked on an aggressive laboratory restructuring that cut back approximately 30% of the overall monies previously paid to the laboratory service sector in Calgary. A unique service delivery model consolidated all institutional and community-based diagnostic testing in a company called Calgary Laboratory Services (CLS in late 1996. CLS was formed by a public/private partnership between the Calgary Regional Health Care Authority (CRHA and MDS-Kasper Laboratories. By virtue of its customer service base and scope of testing, CLS provides comprehensive regional laboratory services to the entire populace. Regional microbiology services within CLS have been successfully consolidated over the past three years into a centralized high volume laboratory (HVL. Because the HVL is not located in a hospital, rapid response laboratories (RRLs are operated at each acute care site. Although the initial principle behind the proposed test menus for the RRLs was that only procedures requiring a clinical turnaround time of more than 2 h stay on-site, many other principles had to be used to develop and implement an efficient and clinically relevant RRL model for microbiology. From these guiding principles, a detailed assessment of the needs of each institution and extensive networking with user groups, the functions of the microbiology RRLs were established and a detailed implementation plan drawn up. The experience at CLS with regards to restructuring a regional microbiology service is described herein. A post-hoc analysis provides the pros and cons of directing and operating a regionalized microbiology service.

    2008-12-01

    Full Text Available Most of the oil and natural gas produced in Brazil derive from offshore fields, virtually concentrated in the Campos Basin off the coast of Rio de Janeiro State. The area is also of intense fisheries interest, involving participation of hand-liners artisanal boats and tuna boats due to the fish aggregating effect of the oil rigs. In order to avoid accidents with the platform "Stena Tay", in operation at Santos and Campos Basins, in 2001 e 2002, an awareness project was developed aiming at avoiding the presence of fishing boats in its 500 m exclusion zone. This paper summarizes the main observations concerning the extent of the fish aggregating effect and the behavior of the fishing boats in the vicinity of the platform.

    This paper reviews the use of acoustic telemetry as a tool for addressing issues in fisheries management, and serves as the lead to the special Feature Issue of Ecological Applications titled “Acoustic Telemetry and Fisheries Management”. Specifically, we provide an overview of the ways in which acoustic telemetry can be used to inform issues central to the ecology, conservation, and management of exploited and/or imperiled fish species. Despite great strides in this area in recent years, there are comparatively few examples where data have been applied directly to influence fisheries management and policy. We review the literature on this issue, identify the strengths and weaknesses of work done to date, and highlight knowledge gaps and difficulties in applying empirical fish telemetry studies to fisheries policy and practice. We then highlight the key areas of management and policy addressed, as well as the challenges that needed to be overcome to do this. We conclude with a set of recommendations about how researchers can, in consultation with stock assessment scientists and managers, formulate testable scientific questions to address and design future studies to generate data that can be used in a meaningful way by fisheries management and conservation practitioners. We also urge the involvement of relevant stakeholders (managers, fishers, conservation societies, etc.) early on in the process (i.e. in the co-creation of research projects), so that all priority questions and issues can be addressed effectively.

    Full Text Available Known as the ‘Old Lady’ of Threadneedle Street, the Bank of England is the central bank of the United Kingdom. Founded in 1694, the Bank of England is standing at the centre of the United Kingdom’s financial system, and is committed to promoting and maintaining monetary and financial stability as its contribution to a healthy economy. In our opinion, it is very important to analyze the Bank of England’s monetary policy strategy, starting from 1992 – adoption of the inflation target and the evolution of it’s monetary policy strategy, through an important feature – delegating operational accountability regarding the monetary policy in 1997 as well as the appropriate institutional framework. More over, it is important to analyze the Bank of England’s performances before and after granting central bank independence.

  1. Urban Recreational Fisheries in the Australian Coastal Zone: The Sustainability Challenge

    Directory of Open Access Journals (Sweden)

    Daryl P. McPhee

    2017-03-01

    Full Text Available Recreational fishing is an important wildlife harvesting activity in urban coastal areas, and recreational harvest in these areas can frequently exceed the commercial harvest. Recreational fishing is a key way that many members of the public experience the environment. The activity enhances social capital, promotes respect for nature, provides health benefits and can provide economic benefits to coastal communities. It is also an important driver of the science on aquatic animals and habitats, and an important tangible reason for many members of the public to conserve and protect aquatic resources. Overall, there has been little specific consideration of urban recreational fisheries management in Australia, despite the paramount importance of urban areas as a focus of recreational fishing activity. This paper identifies that in order to maximize individual and societal benefits from recreational fishing, there needs to be a refocussing of management with the aim of being more holistic. Historically, fisheries management in Australia has focused on maximum sustainable yield (MSY or maximum economic yield (MEY which is relevant for the commercial fishing sector, but neither of these is directly relevant to recreational fisheries. This paper identifies that Urban Fisheries Management Plans are required that recognize the specific issues associated with urban recreational fisheries. These plans need to coordinate within and between levels of government and have clear management objectives relevant to urban recreational fisheries. Enhanced opportunities for meaningful citizen science can be incorporated at multiple levels within these plans and this can engender public support for environmental stewardship, as well as fill a very important gap in the knowledge base necessary for managing the activity. As urban recreational fisheries are often occurring in highly modified or degraded habitats, a central element of these plans needs to be habitat

  2. Hemodynamics of Central Venous Catheters: experiments and simulations

    Central venous catheters (CVC) are used to provide vascular access during hemodialysis in patients with end-stage kidney disease. Despite several advantages and widespread use, CVCs have a high incidence rate of clot formation during the interdialytic phase (48 hrs). In an attempt the prevent clot formation, hospitals routinely administer heparin, an anticoagulant, into the catheter after a dialysis session. It has been reported, however, that up to 40% of the heparin solution will leak into the blood stream during the interdialytic phase, placing the patient at risk for systemic bleeding incidences. The aim of this study is to determine the role that advective-diffusive transport plays in the heparin leaking process. Numerical simulations of heparin convective mass transfer have been conducted, showing that while advective losses may be significant at the tip, previous studies may be overestimating the total amount of heparin leakage. To validate the quantitative prediction from the simulations, P.L.I.F. is used to experimentally measure heparin transport from CVCs placed in an idealized Superior Vena Cava with physically accurate pulsatile flow conditions. Improved understanding of flow near the catheter tip is applied to improve catheter design and heparin locking procedures.

  3. Enhancing Experiment Central Service Reliability: from delivery to security and virtualization

    Donno, Flavia; Buzykaev, Alexey; Saiz Santos, Maria Dolores

    2011-01-01

    The four LHC experiments rely on experiment specific services running on machines mainly located at CERN. Some of these services have been rated by the experiments as very critical: any loss or degradation of performance has a major impact on the experiment's production and analysis activities. It is therefore important to provide a reliable and robust operational environment. In this work we describe the strategy based on service deployment, security and virtualization adopted to enhance the reliability of ATLAS and CMS central services.

    Pomfret, Richard

    2010-12-01

    Full Text Available This paper reviews the experience of the five Central Asian countries in the two decades since independence. In the 1990s the five countries looked like a natural experiment. They had similar initial conditions, but different transition strategies. Today that does not appear to have been a useful research agenda, which raises some broader questions for comparative economic studies.

    Full Text Available Descartes são comuns na pesca comercial, sendo avaliados para apoiar o manejo da pesca na região. Por meio de acompanhamentos diários das pescarias da frota comercial de Tefé, foi descrito o descarte de pescado no médio Solimões. Utilizando análises de correlação e covariância, foram avaliados fatores que determinam o descarte com três modalidades distintas de pesca. Os pescadores selecionaram o pescado no momento da captura por espécie e tamanho. As espécies de pescados mais descartados foram jaraquis, tucunarés e branquinhas, porém os mais freqüentes, no descarte, foram espécies dos Siluriformes. Os apetrechos de pesca analisados apresentaram diferenças nas características de seu descarte. O descarte foi menor na enchente-cheia (5-17% da captura, conforme apetrecho que durante a vazante-seca (20-62%, conforme apetrecho. Discards are common in commercial fishery, and are evaluated in order to support fisheries management in the region. Fish discards in themiddle Solimões River were described through daily monitoring of fishing activities by the commercial fleet of the town of Tefé. By making use of analyses of correlation and covariance, determinant factors for discards in three different types of fisheries wereevaluated. The crew selected the fish at the moment of capture, by species and size. Among the most discarded fish species were jaraquis Semaprochilodus spp., tucunarés Cichla spp. and branquinhas Curimatidae; however, the most frequently discarded were Siluriform species. The fishing gear analyzed featured differences in their discarding characteristics. Discard was lower during the flood period (5-17% of catches, depending on gear than during the dry season (20-62% of catches, depending on gear.

    Highlights: > Central sloshing experiments are simulated with meshless SPH-based method. > Presence of obstacles and asymmetries on the central peak formation are studied. > The high central peak is observed only in strongly symmetrical geometry. > Results are compared with sloshing simulations by 3D reactor code SIMMER-IV. - Abstract: Liquid sloshing phenomena can be observed whenever a liquid in a container has an unrestrained surface and can be excited. A particular type of sloshing motion can occur during the core meltdown of a liquid metal cooled reactor (LMR) and can lead to a compaction of the fuel in the center of the core possibly resulting in energetic nuclear power excursions. This phenomenon was studied in series of 'centralized sloshing' experiments with a central water column collapsing inside the surrounding cylindrical tank. These experiments provide data for a benchmark exercise for accident analysis codes. To simulate 'centralized sloshing' phenomena, a numerical method should be capable to predict the motion of the free surface of a liquid, wave propagation and reflection from the walls. In this study, a meshless method based on smoothed particle hydrodynamics (SPH) for the simulation of a 3D free surface liquid motion has been developed. The proposed method is applied to the simulation of 'centralized sloshing' experiments. Simulation results are compared with the experimental results as well as with results of computations performed with the 3D code SIMMER-IV which is an advanced reactor safety analysis code that implements the traditional mesh-based numerical method. In a series of numerical calculations it is shown that overall motion of the liquid is in a good agreement with experimental observations. Dependence on the initial and geometrical symmetry is studied and compared with experimental data.

    Full Text Available Global catches of marine fishery resources declined during the last decades; however, there has been a trend of increasing exploitation of deepwater resources that are especially vulnerable to depletion. Such a tendency was noticeable in Pacific Latin América, too. In Costa Rica, the vast majority of the commercial fishing activities are concentrated on the Pacific coast. The target species for the deepwater fishery in Costa Rica are the two pandalids Heterocarpus affinis and H. vicarius as well as Solenocera agassizii, the latter one being the most important in terms of annual landings. Here we compile the information available from Costa Rica about each of the three target species. Furthermore, we describe research activities related to the Costa Rican deepwater resources and present available data about by-catch and discards in this fishery. Finally, the current situation of the administration and management of these resources in Costa Rica is described. Strengthening collaboration between governmental agencies, the fishery sector, non-governmental organizations, and the academic sector is recommended to avoid an uncontrolled overfishing of these valuable deepwater resources along the Pacific coast of Costa Rica.Las capturas globales de los recursos marinos pesqueros disminuyeron durante las últimas décadas. Sin embargo, se ha observado una tendencia de aumento en la explotación de los recursos de aguas profundas, los cuales son especialmente vulnerables a la extracción. Esta tendencia ha sido notable también en la pesca a lo largo del Pacífico de Latino América. En Costa Rica, la mayoría de las actividades pesqueras comerciales se concentran en la costa del Pacífico. Las especies objetivo de la pesca de aguas profundas en Costa Rica son los dos pandálidos Heterocarpus affinis y H vicarius así como Solenocera agassizii, siendo esta última la más importante respecto a las capturas anuales.

  20. The rebuilding imperative in fisheries: Clumsy solutions for a wicked problem?

    Science.gov (United States)

    Khan, Ahmed S.; Neis, Barb

    2010-10-01

    There is mounting evidence that global fisheries are in crisis and about 25-30% of fish stocks are over exploited, depleted or recovering. Fish landings are increasingly coming from fully-exploited and over-exploited fisheries, and from intensive aquaculture that often relies indirectly on reduction fisheries. This poses severe challenges for marine ecosystems as well as food security and the livelihoods of resource-dependent coastal communities. Growing awareness of these social, economic and ecological consequences of overfishing is reflected in an expanding literature which shows that reducing fishing effort to allow fish stocks to recover has been the main focus of management efforts, but successful examples of stock recovery are few. An alternative, less explored social-ecological approach focuses on rebuilding entire ‘fish chains’ from oceans to plate. This paper supports this alternative approach. A review and synthesis of stock rebuilding initiatives worldwide suggests effective governance is central to rebuilding, and fisheries governance is a wicked problem. Wicked problems are complex, persistent or reoccurring and hard to fix because they are linked to broader social, economic and policy issues. This review and analysis implies that, due to socioeconomic and sociopolitical concerns, fisheries governance challenges are particularly wicked when dealing with collapsed fisheries and rebuilding efforts. The paper concludes that rebuilding might benefit from experimenting with clumsy solutions. Clumsy solutions are exploratory, include inputs from a broad range of stakeholders along the fish chain, and require information sharing, knowledge synthesis, and trust building. Moreover, clumsy solutions that address power relations, collective action dilemmas, and the fundamental question of ‘rebuilding for whom’ are essential for stewardship, equity and long-term resource sustainability.

    Nearshore areas off of west-central Maui, Hawai‘i, once dominated by abundant coral coverage, now are characterized by an increased abundance of turf algae and macroalgae. In an effort to improve the health and resilience of the coral reef system, the Kahekili Herbivore Fisheries Management Area was established by the State of Hawai‘i, and the U.S. Coral Reef Task Force selected the Kā‘anapali region as a priority study area. To support these efforts, the U.S. Geological survey mapped nearly 5 km2 of sea floor from the shoreline to water depths of about 30 m. Unconsolidated sediment (predominantly sand) constitutes 65 percent of the sea floor in the mapped area. Reef and other hardbottom potentially available for coral recruitments constitutes 35 percent of the mapped area. Of this potentially available hardbottom, only 51 percent is covered with a minimum of 10 percent coral, and most is found between 5 and 10 m water depth.

  2. Global Sushi: The Political Economy of the Mediterranian Bluefin Tuna Fishery in the Modern Era

    2015-08-01

    Full Text Available The bluefin tuna fishery in the Mediterranean has a long history of human interaction. In recent times, this fishery has become the central source of bluefin tuna for core nations, particularly Japan. This process was set off in large part by the growth of global fish markets, driven by the valuable sushi and sashimi market, and overfishing of other bluefin stocks in other parts of the world. The transformation of this fishery from an artisanal trap fishery to a globalized industrial fishery has had a number of social and environmental consequences. Based on in-depth fieldwork and historical research, this paper examines the political economy of the bluefin tuna fishery in the Mediterranean, with a focus on Sicily. It provides a descriptive history of the changing conditions in this fishery, paying special attention to the modern fishery. This research contributes to the discussions regarding the globalization and industrialization of agri-foodsystems and environmental degradation.

    Full Text Available In the tropical and subtropical coastal zone, were highly diverse fish communities occur, it is important to study the small scale fisheries exploiting these communities. For this study, 219 fishing days were carried out in Bahia de Navidad, Jalisco, Mexico. Four gillnets with different mesh sizes (76.2, 88.9, 101.6 and 114.3 mm were used for the fishing operations, from April 1994 to March 1995 and from January 1998 to December 2000. A total of 26126 organisms weighting 11680 kg were caught. One hundred and eighty three species belonging to 57 families and 19 orders were identified. Ten species accumulated more than 60% of the total abundance and biomass, the remaining species (173 individually contributed with less than 2% of the total abundance and biomass. The most important species in the catch were Microlepidotus brevipinnis, Caranx caballus, Haemulon flaviguttatum, Scomberomorus sierra, C. caninus, C. sexfasciatus, Lutjanus guttatus and L. argentiventris. The catch per unit of effort showed a large variation during the study, both in number and biomass. On average, 110 fishes and 48.5 kg fishing day-1 were caught. The maximum values were recorded during January and October 1998 (250 fishes and 100 kg fishing day-1, and the minimum values were recorded during September and November 1994 (25 org. and 10 kg fishing day-1.

    Pitcher, Tony J; Cheung, William W L

    2013-09-30

    Recent work suggesting that fisheries depletions have turned the corner is misplaced because analysis was based largely on fisheries from better-managed developed-world fisheries. Some indicators of status show improvements in the minority of fisheries subjected to formal assessment. Other indicators, such as trophic level and catch time series, have been controversial. Nevertheless, several deeper analyses of the status of the majority of world fisheries confirm the previous dismal picture: serious depletions are the norm world-wide, management quality is poor, catch per effort is still declining. The performance of stock assessment itself may stand challenged by random environmental shifts and by the need to accommodate ecosystem-level effects. The global picture for further fisheries species extinctions, the degradation of ecosystem food webs and seafood security is indeed alarming. Moreover, marine ecosystems and their embedded fisheries are challenged in parallel by climate change, acidification, metabolic disruptors and other pollutants. Attempts to remedy the situation need to be urgent, focused, innovative and global.

    2004-02-01

    The aim of this study was to explore the postoperative pain experiences of Central Australian Aboriginal women and the subsequent interpretation of that pain experience by non-Aboriginal female nurses. Qualitative study using grounded theory methodology. Postoperative surgical setting of a Central Australian regional hospital. Five Aboriginal female clients who had undergone a surgical procedure, eight non-Aboriginal female nurses and four Aboriginal female health workers employed by a Central Australian regional hospital. Aboriginal women have culturally appropriate ways of expressing and managing pain that are not well understood by non-Aboriginal female nurses. In addition, the Aboriginal women inappropriately endow non-Aboriginal nurses with the same powers and skills expected of healers from their culture. This phenomenon resulted in the non-Aboriginal nurses lacking the cultural insight and the appropriate knowledge and tools required to assess and manage the postoperative pain of Central Australian Aboriginal women effectively or efficiently. Non-Aboriginal nurses have a profound knowledge deficit about the postoperative pain experiences of Central Australian Aboriginal women. This deficit is evident through the use of culturally inappropriate and unreliable pain assessment strategies and tools and the misinterpretation of traditional pain relief strategies, such as the use of pituri, rubbing and centreing. The findings of this study suggested that nurse/client interactions related to language and role interpretation were in cultural conflict. The nurses expected the Aboriginal women to adopt pain behaviours as understood from the nurses' culture. The nurses anticipated that the client would contribute to their own care by communicating pain experiences in ways that are familiar and are believed to be universal. The Aboriginal women expected the nurses to conduct business similar to that of their own traditional tribal healers, 'to see within' and to 'just

  14. Supply regimes in fisheries

    DEFF Research Database (Denmark)

    Nielsen, Max

    2006-01-01

    Supply in fisheries is traditionally known for its backward bending nature, owing to externalities in production. Such a supply regime, however, exist only for pure open access fisheries. Since most fisheries worldwide are neither pure open access, nor optimally managed, rather between the extremes......-economic supply model with mesh sizes is developed. It is found that in the presence of realistic management schemes, the supply curves are close to vertical in the relevant range. Also, the supply curve under open access with mesh size limitations is almost vertical in the relevant range, owing to constant...... recruitment. The implications are that the effects on supply following from e.g. trade liberalisation and reductions of subsidies are small in several and probably most fisheries worldwide.

Moreover, we estimated diet overlap for three different size classes (15.1 cm TL. The results revealed exclusively two groups of benthic prey items: crustaceans (30% and teleost fish (70% in their diet. The most frequent preys were pandalid shrimps Plesionika trispinus (% O = 17 and the fathom mora Physiculus rastrelliger (% O = 12. The greatest diversity and frequency of abundance of food items was observed in intermediate-sized individuals (10.1-15.0 cm TL. Small-sized L. spilurus ( 15.0 cm TL preyed on large-sized stomatopods and teleost fish. There was a clear diet overlap between small and intermediate-sized L. spilurus (p 0.05. Our results suggest that L. spilurus feeds exclusively on crustaceans (Decapoda and Stomatopoda and benthic teleost fish along the Pacific of Costa Rica. While small and large-sized individuals showed a more pronounced selectivity for certain prey items, the high diversity of benthic prey items observed in intermediate-sized specimens suggest a more opportunistic foraging behavior.

Larval abundance was negatively correlated with depth and distance from the coast but positively correlated with sea surface temperature. No correlation with sea surface salinity was found. The highest larval abundance was observed in June at 20-25 m depth, while adults were mostly found at 30-35 m depth. This species is mainly concentrated in the area of influence of the Guadalquivir River but is very scarce in the rest of the study area. The maturation of the ovary and the activity of the sexual accessory glands begin in early winter. The population is age-structured in three year classes and females reach first maturity within the second year class, at 23.7 mm carapace length.

    The rapid increase in body size and abundance of most species inside Management and Exploitations Areas for Benthic Resources (MEABRs) has led to the proposal of these areas as a good complement for achieving the conservation objectives of Marine Protected Areas (MPAs). However, when evaluating MEABRs and MPAs as conservation and/or management tools, their impact upon parasite populations has rarely been considered, despite the fact that epidemiological theory suggests an increased susceptibility to parasitism under high population abundance. We evaluated the effects of MEABRs on the parasite abundance of Proctoeces lintoni and its impact on the growth of the host limpet Fissurella crassa in central Chile. Parasitic magnitude was higher inside MEABRs than in Open-Access Areas, and parasitized limpets showed a greater shell length, muscular foot biomass, and gonadosomatic index compared to non-parasitized limpets of the same age. Our results suggest that the life cycle of P. lintoni and, consequently, its trophic links have been strengthened inside MEABRs. The increased growth rate could reduce the time required to reach the minimum catch size and increase the reproductive and muscular output of the host population. Thus, parasitism should be considered in the conservation and management of economically important mollusk hosts.

    A framework for target diagnostic centralized control system (TDCCS) in inertial confinement fusion (ICF) experiment has been developed. The developed framework is based on the common object request broker architecture (CORBA) standard and part of the concept from the ICFRoot (a framework based on ROOT for ICF experiments) framework design. This framework is of a component architecture, including a message bus, command executer, status processor, parser and proxy. To test the function of the framework, a simplified prototype of the TDCCS has been developed as well.

    Centralizing hyperacute stroke unit (HASU) care services allows improved access to thrombolysis but could be associated with worse patient experience, particularly when early repatriation to a local stroke recovery unit occurs as this may result in discontinuity of care. A centralized model of care was introduced in London, United Kingdom, with 8 HASUs providing acute care for the whole 8.3 million population, with repatriation on day 3 to a local stroke recovery unit. The patient and carer experience of this model of care has not been previously reported. We undertook a prospective observational study of the new model of care in the South West London sector. Patient and carer experiences were evaluated using a modified Picker Questionnaire. Separate questionnaires were used for patients discharged directly home from the HASU, those repatriated to local stroke recovery units, and for carers of patients admitted to the HASU. Despite moving from a selected to nonselected admission pattern, thrombolysis rates increased from 6% to 9%. High satisfaction rates were reported among both patients and carers. Patients discharged directly home had higher satisfaction levels than those requiring repatriation to their local stroke unit, who were older and had more severe stroke. A total of 47% of carers expressed anxiety over the repatriation from the HASU back to the local stroke recovery unit, but few patients and carers reported an impact of this move on patient recovery. Centralized HASU care is associated with good levels of patient and carer satisfaction.

    Fishery resources are a vital source of food and make valuable economic contributions to the local communities involved in fishery activities along the 850 km stretch of the Tanzania coastline and numerous islands. Small-scale artisanal fishery accounts for the majority of fish catch produced by more than 43 000 fishermen in the country, mainly operating in shallow waters within the continental shelf, using traditional fishing vessels including small boats, dhows, canoes, outrigger canoes and dinghys. Various fishing techniques are applied using uncomplicated passive fishing gears such as basket traps, fence traps, nets as well as different hook and line techniques. Species composition and size of the fish varies with gear type and location. More than 500 species of fish are utilized for food with reef fishes being the most important category including emperors, snappers, sweetlips, parrotfish, surgeonfish, rabbitfish, groupers and goatfish. Most of the fish products are used for subsistence purposes. However, some are exported. Destructive fishing methods such as drag nets and dynamite fishing pose a serious problem as they destroy important habitats for fish and other organisms, and there is a long-term trend of overharvested fishery resources. However, fishing pressure varies within the country as fishery resources are utilized in a sustainable manner in some areas. For this report more than 340 references about Tanzanian fishery and fish ecology were covered. There are many gaps in terms of information needed for successful fishery management regarding both basic and applied research. Most research results have been presented as grey literature (57%) with limited distribution; only one-fifth were scientific publications in international journals.

  2. Freedom and poverty in the fishery commons

    2010-01-01

    Full Text Available Abstract In fisheries, alleviating poverty sometimes requires strategies that are inherently in conflict. When aiming to develop a fishery as a means to reduce poverty, its common pool resource basis might be undermined, resulting in greater poverty. But poverty in fisheries is also linked to, or a part of deeper social issues and processes, for instance, the marginalization and exclusion of certain communities. Poverty also has many factors— income, health, literacy, gender, power, security, etc.—all of which make poverty alleviation a particularly “wicked problem” that would require a broad process of political, social and institutional reform. In other words, poverty alleviation is not only an issue of sustainable resource management but also one of societal governance. Drawing from research in small-scale fisheries communities in Nicaragua, Tanzania, and Bangladesh, this paper describes how fishing people cope with poverty. The paper discusses what the governance implications are for alleviating poverty at individual, household and community levels, and argue that both the definition of poverty and poverty alleviation in small-scale fisheries must be rooted in real life experiences.

  5. "A Future for Fisheries?" Setting of a Field-based Class for Evaluation of Aquaculture and Fisheries Sustainability

    Macko, Stephen; O'Connell, Matthew

    2016-04-01

    For the first time in 2015, aquaculture yields approximately equaled global wild capture fisheries. Are either of these levels of production sustainable? This course explored the limitations of both sources of fishery landings and included legal limitations, environmental concerns and technological problems and adaptations. It made use of visits to aquaculture facilities, government laboratories like NOAA , as well as large fish distribution centers like J.J. McDowell's Seafood (Jessup, MD), and included presentations by experts on legalities including the Law of the Sea. In addition, short day-long trips to "ocean-related" locations were also used to supplement the experience and included speakers involved with aquaculture. Central Virginia is a fortunate location for such a class, with close access for travel to the Chesapeake Bay and numerous field stations, museums with ocean-based exhibits (the Smithsonian and National Zoo) that address both extant and extinct Earth history, as well as national/state aquaria in Baltimore and Virginia Beach. Furthermore, visits to local seafood markets at local grocery stores, or larger city markets in Washington, Baltimore and Virginia Beach, enhance the exposure to productivity in the ocean, and viability of the fisheries sustainability. Sustainability awareness is increasingly a subject in educational settings. Marine science classes are perfect settings of establishing sustainability awareness owing to declining populations of organisms and perceived collapse in fisheries worldwide. Students in oceanography classes often request more direct exposure to actual ocean situations or field trips. This new approach to such a course supplement addresses the requests by utilizing local resources and short field trips for a limited number of students to locations in which Ocean experiences are available, and are often supported through education and outreach components. The vision of the class was a mixture of classroom time

    Trauma has been understudied among Latina immigrants from Central and South America. This study examined the types and context of trauma exposure experienced by immigrant women from Central America, South America, and Mexico living in the United States. Twenty-eight women seeking care in primary care or social service settings completed life history interviews. The majority of the women reported some type of trauma exposure in their countries of origin, during immigration, and/or in the United States. In the interviews, we identified types of trauma important to the experience of these immigrants that are not queried by trauma assessments typically used in the United States. We also identified factors that are likely to amplify the impact of trauma exposure. The study highlights the importance of utilizing a contextualized approach when assessing trauma exposure among immigrant women.

  8. Resisting violence against women in Central America: the experience of a feminist collective.

    Science.gov (United States)

    Profitt, N J

    1994-01-01

    This article explores how violence against women was resisted in Central America. It was observed that women in Central America have "developed a feminist critical consciousness of the negative responses to their personal and political transformation." This consciousness served as a bridge between various women groups and movements such as the Women's Collective Pancha Carrasco and other mutual support groups. This paper made clear that any organization addressing the issue of violence against women should take place in a context of a political framework where women can make sense of their resistance. Feminist social work practice should therefore be aimed towards a deeper understanding of the social and political dimensions of women. With this, feminist workers shall be able to create a feminist politics that is rooted on the collectivity of the experiences of women and resistance to abuse and violence.

    2002-12-01

    The investigations of the RV SONNE cruise SO161 during the SPOC experiment (Subduction Processes Off Chile) concentrated on the area of the central Chilean margin west off Valparaiso. The main goal of this experiment is to investigate the effects of subducting oceanic seafloor relief on the seismicity of this domain. A marine array of 23 ocean bottom hydrophones and seismometers (OBH/S) was deployed for a period of ten weeks to monitor local earthquakes from this part of the Chilean margin where volcanic structures like the aseismic Juan Fernandez Ridge enter the trench. A strong decrease in dip angle of the subducting plate (flat slab) is observed here, resulting in a segmentation of the margin. The flat slab segment correlates with the absence of Quaternary volcanism and a central valley on the South American plate. It is assumed that a connection between the buoyancy of thickened oceanic crust and the occurrence of shallow subduction earthquakes exists. We present preliminary results of hypocenter determinations, founded on about 300 localisable events based on the OBH/S recordings. The distribution of hypocenters shows a considerable seismic activity within the 15 km - 50 km depth range. The special focus on the transitional domain of the slope allowed us to map in detail the seaward termination of the seismogenic zone. In addition, we used seismological land data, recorded from the Central Chilean Network (CCN) and a number of temporary landstations to supplement the marine data set. Comparative and joint hypocenter analysis from both marine and land data, increases the precision of locations and allows an assessment of systematic errors. We can show the need of both, on- and offshore data sets, to determine offshore earthquake locations with high precision. The seismological investigations are in close collaboration with the active seismic studies carried out during the scope of the SPOC experiment.

    COMPASS is a fixed-target experiment at the CERN SPS which recorded a data set with an incident proton beam impinging on a liquid hydrogen target in order to study the central production of light scalar mesons. We select events with two protons and two pseudo-scalar mesons in the final state and decompose their angular distribution in terms of partial-wave amplitudes. Fits to the mass-dependence of these amplitudes are used to determine the Breit-Wigner parameters of scalar resonances.

    2017-01-01

    The size and evolution of the medium created in a heavy-ion collision depends on collision geometry. Experimentally collisions can be characterized by the measured particle multiplicities around midrapidity or by the energy measured in the forward rapidity region, which is sensitive to the spectator fragments. In the Compressed Baryonic Matter (CBM) experiment at the future Facility for Antiproton and Ion Research (FAIR) the multiplicity of produced particles is measured with the silicon tracking system (STS). The projectile spectator detector (PSD) measures the energy of spectator fragments. We present the procedure of collision centrality determination in CBM and its performance using the PSD and the STS information.

    De Salvo, A; Luci, C

    2002-01-01

    We describe the central error analyser (CEA) system developed for the L3 experiment at CERN. The goal was to have a centralized environment to collect error and diagnostic messages coming from the several subsystems of the detector and of the data acquisition system as well as from the slow control. The CEA has been operational during the last three years of the L3 data taking, namely from 1998 till 2000. It reduced significantly the time needed to detect and fix DAQ failures, resulting in an overall efficiency exceeding 90%. We describe how the system handled the error messages and how it managed at a central level the correlation among different error situations. The mechanism to exchange messages among independent processes, running on different platforms like VAX-VMS, HP-Unix and PC-Linux, was based on TCP client-server relationships, while the whole CEA architecture was implemented in C++ on a Linux PC platform and it was based on a relational database (postgresql).

    Full Text Available A malhadeira é um apetrecho de pesca frequentemente utilizado na pesca regional. O presente estudo visa verificar características das malhadeiras utilizadas nos diversos subsistemas da Amazônia Central, seu uso e a aplicação de normas legais relacionadas. Os dados foram obtidos por meio de entrevistas com pescadores em Manaus entre 1994 e 2004 e em Manacapuru entre 2001 e 2004. Os resultados indicaram que o apetrecho responde em média a 14% da produção pesqueira de Manaus, com tendência a diminuição e a 24,5% de Manacapuru, com estabilidade interanual. As freqüências modais recentes do tamanho de malha estiveram entre 50-60 mm no desembarque em Manaus, mas em Manacapuru foram mais diversas, entre 20 mm e 90 mm. A moda do comprimento das redes foi de 100 m em ambos portos, mas se em Manaus correspondem a cerca de 90% das registradas, em Manacapuru não são nem 50% do total. Quanto à freqüência de ocorrência de uso da malhadeira nos subsistemas da Amazônia Central que desembarcaram em Manaus, destaca-se o rio Purus (47,8%, enquanto que para Manacapuru predominou explotação no Baixo Solimões (94,3%. A composição das capturas variou entre os anos analisados, destacando cinco principais pescados que compõem mais de 70% das capturas: tambaqui, aruanã, tucunaré, curimatá, pirapitinga. Com relação às restrições no tamanho de malha, a maioria dos apetrechos têm tamanho de malha passível de uso ilegal, similarmente aos comprimentos das mesmas.

    Full Text Available By passing the law on state support in agriculture, fishery and forestry the former support system has been changed. Fishery support beneficiaries can use several kinds of support and help. Former financial stimulations for fishery regulated by law from 1995 to 1st January 2003 were settled by the production stimulation model. Besides that well received model, there are the capital investment model, the support in production insurance, the right to use blue diesel, and granting credit for production of freshwater and saltwater fry, adult fish and shells. These five models of support and help can be used by freshwater and saltwater fish and shell breeders, while for fishing the marine fish the production stimulation model is applied (fishing of small pelagic fish, as well as the capital investment model and right to use blue diesel. Marine and freshwater processors can use the production stimulation and the capital investment model. All these models have in common the fact that all physical and legal entities registered for fishing activities (having licence for commercial fishery, aquaculture (the licence for aquaculture or the one for fish and other marine organisam breeding and processing (having the regulated veterinarian and sanitary conditions, the registration document and having been registered in the List of approved facilities have the right to use them.

  3. Job Satisfaction in Fisheries Compared.

    Pollnac, Richard; Bavinck, Maarten; Monnereau, Iris

    2012-10-01

    This article draws comparative lessons from seven job satisfaction studies on marine capture fishing that were recently carried out in nine countries and three geographical regions-Asia, Africa, and the Caribbean. The seven studies made use of an identical job satisfaction assessment tool and present information on a selection of métiers mainly in the small-scale and semi-industrial fishing sectors. The responses manifest statistically significant geographical variation. Multidimensional plots and cluster analyses lead the authors to identify three clusters: (1) Southeast Asian (Vietnam and Thailand); (2) Caribbean (Belize, Nicaragua, Dominican Republic) and (3) Afro-Indian (Senegal, Guinea Bissau, and India). Jamaica is a significant outlier. On a general level, the authors conclude that fishers who report that they are not interested in leaving the occupation of fishing score higher on three traditional job satisfaction scales-basic needs, social needs and self actualization. Those who say they would leave fishing for another occupation are younger, have less fishing experience and smaller households. The latter findings are of relevance with regard to the pressing need, felt by fisheries managers, to move fishers out of the fishery.

    BPA proposes to fund several fishery-related activities in the Yakima River Basin. These activities, known as the Yakima Fisheries Project (YFP), would be jointly managed by the State of Washington and the Yakima Indian Nation. The YFP is included in the Northwest Power Planning Council`s (Council`s) fish and wildlife program. The Council selected the Yakima River system for attention because fisheries resources are severely reduced from historical levels and because there is a significant potential for enhancement of these resources. BPA`s proposed action is to fund (1) information gathering on the implementation of supplementation techniques and on feasibility of reintroducing coho salmon in an environment where native populations have become extinct; (2) research activities based on continuous assessment, feedback and improvement of research design and activities ({open_quotes}adaptive management{close_quotes}); and (3) die construction, operation, and maintenance of facilities for supplementing populations of upper Yakima spring chinook salmon. Examined in addition to No Action are two alternatives for action: (1) supplementation of depressed natural populations of upper Yakima spring chinook and (2) that same supplementation plus a study to determine the feasibility of reestablishing naturally spawning population and a significant fall fishery for coho in the Yakima Basin. Alternative 2 is the preferred action. A central hatchery would be built for either alternative, as well as three sites with six raceways each for acclimation and release of spring chinook smolts. Major issues examined in the Revised Draft EIS include potential impacts of the project on genetic and ecological resources of existing fish populations, on water quality and quantity, on threatened and endangered species listed under the Endangered Species Act, and on the recreational fishery.

  16. The invasive ctenophore Mnemiopsis leidyi in northern European waters and its potential impact on fisheries

    DEFF Research Database (Denmark)

    Jaspers, Cornelia

    The recent invasion by Mnemiopsis in northern European waters has lead to concerns for fishery interests especially in the central Baltic Sea, where it overlaps with commercially important cod recruits on their spawning grounds. We present laboratory feeding rate experiments along with video...... selected against cod eggs. Application of our clearance rates to in situ abundances confirmed that Mnemiopsis has a negligible direct predation impact on cod offspring. Further, due to drastically reduced reproduction rates at low salinities, occurrence of Mnemiopsis in the central Baltic appears...... to be dependent on advection, and is unlikely to reach large population sizes. Hence, Mnemiopsis constitutes neither a direct nor a potential indirect threat to the cod population in the central Baltic. However, its large reproduction potential in high saline areas with 11,500 eggs ind-1 d-1 and observed high...

    This paper describes the design, authoring, and development of interactive, computerized, multimedia clinical simulations in pediatric rheumatology/immunology and related musculoskeletal diseases, the development and implementation of a high speed information management system for their centralized storage and distribution, and analytical methods for evaluating the total system's educational impact on medical students and pediatric residents. An FDDI fiber optic network with client/server/host architecture is the core. The server houses digitized audio, still-image video clips and text files. A host station houses the DB2/2 database containing case-associated labels and information. Cases can be accessed from any workstation via a customized interface in AVA/2 written specifically for this application. OS/2 Presentation Manager controls, written in C, are incorporated into the interface. This interface allows SQL searches and retrievals of cases and case materials. In addition to providing user-directed clinical experiences, this centralized information management system provides designated faculty with the ability to add audio notes and visual pointers to image files. Users may browse through case materials, mark selected ones and download them for utilization in lectures or for editing and converting into 35mm slides.

    Marine protected areas (MPAs) are attaining increasing importance in the management of marine ecosystems. They are effective for conservation in tropical and subtropical areas (mainly coral and rocky reefs), but it is debated whether they are useful in the management of migratory fish stocks in open temperate regions. World War II created a large marine area within which commercial fishing was prevented for 6 years. Here we analyse scientific trawl data for three important North Sea gadoids, collected between 1928 and 1958. Using statistical models to summarise the data, we demonstrate the potential of MPAs for expediting the recovery of over-exploited fisheries in open temperate regions. Our age-structured data and population models suggest that wild fish stocks will respond rapidly and positively to reductions in harvesting rates and that the numbers of older fish in a population will react before, and in much greater proportion, than their younger counterparts in a kind of Mexican wave. Our analyses demonstrate both the overall increase in survival due to the lack of harvesting in the War and the form of the age-dependent wave in numbers. We conclude that large closed areas can be very useful in the conservation of migratory species from temperate areas and that older fish benefit fastest and in greater proportion. Importantly, any rise in spawning stock biomass may also not immediately result in better recruitment, which can respond more slowly and hence take longer to contribute to higher future harvestable biomass levels.

  1. Green growth in fisheries

    DEFF Research Database (Denmark)

    Nielsen, Max; Ravensbeck, Lars; Nielsen, Rasmus

    2014-01-01

    Climate change and economic growth have gained a substantial amount of attention over the last decade. Hence, in order to unite the two fields of interest, the concept of green growth has evolved. The concept of green growth focuses on how to achieve growth in environment-dependent sectors, without...... harming the environment. Fishery is an environment-dependent sector and it has been argued that there is no potential for green growth in the sector owing to global overexploitation, leaving no scope for production growth. The purpose of this paper is to explain what green growth is and to develop...... a conceptual framework. Furthermore, the aim is to show that a large green growth potential actually exists in fisheries and to show how this potential can be achieved. The potential green growth appears as value-added instead of production growth. The potential can be achieved by reducing overcapacity...

  2. Predicting overfishing and extinction threats in multispecies fisheries.

    Burgess, Matthew G; Polasky, Stephen; Tilman, David

    2013-10-01

    Threats to species from commercial fishing are rarely identified until species have suffered large population declines, by which time remedial actions can have severe economic consequences, such as closure of fisheries. Many of the species most threatened by fishing are caught in multispecies fisheries, which can remain profitable even as populations of some species collapse. Here we show for multispecies fisheries that the biological and socioeconomic conditions that would eventually cause species to be severely depleted or even driven extinct can be identified decades before those species experience high harvest rates or marked population declines. Because fishing effort imposes a common source of mortality on all species in a fishery, the long-term impact of a fishery on a species is predicted by measuring its loss rate relative to that of species that influence the fishery's maximal effort. We tested our approach on eight Pacific tuna and billfish populations, four of which have been identified recently as in decline and threatened with overfishing. The severe depletion of all four populations could have been predicted in the 1950s, using our approach. Our results demonstrate that species threatened by human harvesting can be identified much earlier, providing time for adjustments in harvesting practices before consequences become severe and fishery closures or other socioeconomically disruptive interventions are required to protect species.

    CERN Document Server

    Austregesilo, Alexander; Mallot, Gerhard

    The question of the existence of glueballs is one of the unsolved problems in modern particle physics and can be regarded as a stringent test for quantum chromodynamics. Especially the supernumerous states in the light scalar meson spectrum are candidates for the observation of mixing effects between $q\\bar q$ mesons and pure gluonic bound states. On the other hand, the existence and the properties of many resonances in this sector are disputed. The COMPASS experiment was proposed to make significant contributions to this field. COMPASS is a fixed-target experiment at the CERN SPS which focused on light-quark hadron spectroscopy during the data taking periods in 2008 and 2009. A world-leading data set was collected with a $190\\,\\mathrm{GeV}/c$ hadron beam impinging on a liquid hydrogen target in order to study, inter alia, the central production of glueball candidates in the light meson sector. Especially the double-Pomeron exchange mechanism is well suited for the production of mesons without valenc...

    C. P. Welsch

    2004-08-01

    Full Text Available A small electrostatic storage ring is the central machine of the Frankfurt Ion Storage Experiments (FIRE which will be built at the new Stern-Gerlach Center of Frankfurt University. As a true multiuser, multipurpose facility with ion energies up to 50 keV, it will allow new methods to analyze complex many-particle systems from atoms to very large biomolecules. With envisaged storage times of some seconds and beam emittances in the order of a few mm mrad, measurements with up to 6 orders of magnitude better resolutions as compared to single-pass experiments become possible. In comparison to earlier designs, the ring lattice was modified in many details: Problems in earlier designs were related to, e.g., the detection of light particles and highly charged ions with different charge states. Therefore, the deflectors were redesigned completely, allowing a more flexible positioning of the diagnostics. Here, after an introduction to the concept of electrostatic machines, an overview of the planned FIRE is given and the ring lattice and elements are described in detail.

  6. The international regulation of herring, blue whiting and mackerel fishery

    2017-06-01

    Full Text Available The purpose of the fisheries management is to provide the conditions for long-term, high and sustainable fishing. Most of the fish stocks in the North-East Atlantic's are transboundary and straddling, and some international agreements in the field of regulation of their fishing are required for effective management. Achieving multilateral international agreements in the field of fisheries is very difficult and long-term process, because it affects the economic and political interests of the contracting parties. The paper considers results of the analysis of stock dynamics of the most important fishery resources in the North-East Atlantic – herring, blue whiting and mackerel – in different historical periods. As in the past few decades, we have seen periods of both managed and unmanaged fisheries and in relation to the value of stocks of pelagic fish there have been significant fluctuations, in this paper the authors have attempted to estimate the value of concerted international fisheries management to maintain a stable state of stocks of pelagic fish. Implementation of scientific recommendations agreed by the participating countries of ICES and the joint management of the herring stock management contribute to the preservation of stock stable and optimal levels of withdrawal of the object. The historical experience of the international fishing of blue whiting has shown that compliance by states involved in the fishery advice of ICES and its reserve management activities and promotes the good stock condition. To save the mackerel stock within safe biological boundaries it is necessary to achieve the agreed long-term plan for managing its fisheries between all participants in the fishery. In the long term for the conservation of stocks of herring, blue whiting and North East mackerel in the safe biological boundaries, the international regulation of their fisheries based on the scientific recommendations of ICES in the framework of NEAFC and

    This investigation of the leech heartbeat neural network system led to the development of a low resources, real-time, biomimetic digital hardware for use in hybrid experiments. The leech heartbeat neural network is one of the simplest central pattern generators (CPG). In biology, CPG provide the rhythmic bursts of spikes that form the basis for all muscle contraction orders (heartbeat) and locomotion (walking, running, etc.). The leech neural network system was previously investigated and this CPG formalized in the Hodgkin-Huxley neural model (HH), the most complex devised to date. However, the resources required for a neural model are proportional to its complexity. In response to this issue, this article describes a biomimetic implementation of a network of 240 CPGs in an FPGA (Field Programmable Gate Array), using a simple model (Izhikevich) and proposes a new synapse model: activity-dependent depression synapse. The network implementation architecture operates on a single computation core. This digital system works in real-time, requires few resources, and has the same bursting activity behavior as the complex model. The implementation of this CPG was initially validated by comparing it with a simulation of the complex model. Its activity was then matched with pharmacological data from the rat spinal cord activity. This digital system opens the way for future hybrid experiments and represents an important step toward hybridization of biological tissue and artificial neural networks. This CPG network is also likely to be useful for mimicking the locomotion activity of various animals and developing hybrid experiments for neuroprosthesis development.

  11. Spatio-temporal declines in Philippine fisheries and its implications to coastal municipal fishers’ catch and income

    Full Text Available The problem of overexploitation in global fisheries is well-recognized. However, published assessment of fisheries spatio-temporal trends at the national scale is lacking for many high biodiversity developing countries, which is problematic since fisheries management is often implemented at the local or national levels. Here, we present the long-term spatio-temporal trends of Philippine fisheries production based on the landed national fish catch data (1980-2012 and fishers’ interviews. We found that the total Philippine fish catch volume (Metric Tons MT of most capture fisheries throughout the country has either stagnated or declined over the last three decades. The decline is even more prominent when evaluating fisheries trends at the provincial level, suggesting spatial serial depletion of the country’s fisheries. In contrast, the total Philippine fish catch value (US Dollars US$ or Philippine Pesos PHP has continued to increase over time, despite the declining fish catch volume. However, local municipal fishers are experiencing both low fish catch and income, contributing to observable poverty in many coastal communities in the Philippines. The various stakeholders of Philippine fisheries need to recognize the depleted state of Philippine fisheries, and learn from various experiences of collapsed and recovered fisheries from around the world, in order to recover the Philippines’ capture fisheries. Lessons from the literature on collapsed fisheries offer the following options for recovery: (1 regulate or reduce fisheries exploitation and other human activities impacting the fisheries to allow fisheries to rebuild or recover, (2 enforce effective networks of marine reserves, (3 engage fishers, consumers, and other stakeholders in fisheries management, (4 improve fisheries science, monitoring, and management capacities, and (5 provide alternative livelihood, skills, and improved education to fishers and their families.

  13. Projected Scenarios for Coastal First Nations' Fisheries Catch Potential under Climate Change: Management Challenges and Opportunities.

    Weatherdon, Lauren V; Ota, Yoshitaka; Jones, Miranda C; Close, David A; Cheung, William W L

    2016-01-01

    Studies have demonstrated ways in which climate-related shifts in the distributions and relative abundances of marine species are expected to alter the dynamics and catch potential of global fisheries. While these studies assess impacts on large-scale commercial fisheries, few efforts have been made to quantitatively project impacts on small-scale subsistence and commercial fisheries that are economically, socially and culturally important to many coastal communities. This study uses a dynamic bioclimate envelope model to project scenarios of climate-related changes in the relative abundance, distribution and richness of 98 exploited marine fishes and invertebrates of commercial and cultural importance to First Nations in coastal British Columbia, Canada. Declines in abundance are projected for most of the sampled species under both the lower (Representative Concentration Pathway [RCP] 2.6) and higher (RCP 8.5) emission scenarios (-15.0% to -20.8%, respectively), with poleward range shifts occurring at a median rate of 10.3 to 18.0 km decade(-1) by 2050 relative to 2000. While a cumulative decline in catch potential is projected coastwide (-4.5 to -10.7%), estimates suggest a strong positive correlation between the change in relative catch potential and latitude, with First Nations' territories along the northern and central coasts of British Columbia likely to experience less severe declines than those to the south. Furthermore, a strong negative correlation is projected between latitude and the number of species exhibiting declining abundance. These trends are shown to be robust to alternative species distribution models. This study concludes by discussing corresponding management challenges that are likely to be encountered under climate change, and by highlighting the value of joint-management frameworks and traditional fisheries management approaches that could aid in offsetting impacts and developing site-specific mitigation and adaptation strategies derived

  17. The Seismogenic Coupling Zone in Central Chile - Amphibious Experiments SPOC (Subduction Processes Off Chile)

    Nearly all interplate megathrust earthquakes occur in the seismogenic coupling zone between converging plates. In the area of the 1960 Chile earthquake (Mw = 9.5), we aim at a quantitative understanding of the seismicity and its relation to processes operating at depth and at the surface. As a first step, the offshore experiment SPOC with RV SONNE was combined with an onshore-offshore, active-passive seismic experiment between 36\\deg and 39\\deg S, crossing the rupture area of the 1960 Chile earthquake. The campaign comprised: (1) a 2-D wide-angle component recording chemical shots and airgun pulses along three consecutive E-W onshore profiles; (2) a seismic reflection experiment in the onshore-offshore transition; and (3) a 3-D component which recorded both active and passive sources. Offshore, the upper plate is split into many segments with pronounced forearc basins and a narrow accretionary wedge. A thick subduction channel seems to cause a non-frontally accreting subduction mode. Along the westernmost part of the southernmost E-W refraction seismic line, the profile spread of the active reflection seismic survey at 38\\deg 15' S was 54 km long, and also recorded the airgun shots of the marine profile with the first 18 km of its spread. Different mainly eastward dipping reflection bands are observed. Between 5-25 km depth the internal structure of the Palaeozoic accretionary wedge is described. Reflections between 16-42 km correlate with Wadati-Benioff seismicity and are interpreted as imaging the top of the downgoing plate. In the central part of the profile a break in reflectivity located below the axis of the coastal cordillera more or less coincides with the intersection between the oceanic plate and the continental Moho. This break in reflectivity also approximately correlates with the downdip end of the seismogenic plate interface as defined by geodetic modelling. These new seismic data provide the geometry of the subduction zone in the area, and hence

    The main goal of the RV SONNE cruise 161 SPOC (Subduction Processes Off Chile), Leg 1 and 4, was to investigate the effects of subducting aseismic ridges and frac- ture zones on the seismicity and structure of the Central Chilean Margin. Scientists from GEOMAR (Kiel), BGR (Hannover), FU Berlin (SFB 267), Universidad de Chile (Santiago) and Instituto Costaricense de Electricidad (Costa Rica) participated in data acquisition and analysis. The SPOC experiment consists of four consecutive legs off Valparaiso, Central Chile. During Leg 1 (October), an array of 23 ocean bottom hydrophons and seismome- ters (OBH/S) was deployed to register local earthquakes. In December (Leg 4), the network was recovered and a total of 125 OBH/S locations were occupied on five wide-angle profiles. They recorded more than 10.000 airgun shots, fired by an airgun array of 20 guns with a total volume of 50 liters. In addition, the wide-angle seis- mic lines were extended by land-based seismometers, operated by the Universidad de Chile, Santiago. Furthermore gravity, magnetics and high resolution bathymetry (SIMRADTM) and sediment echo-sound data (PARASOUNDTM) were recorded. On Legs 2 and 3, the BGR carried out a multi-channel reflection (MCS) seismic survey. Preliminary analysis of the data shows that a considerable number of local earthquakes has been recorded by the passive seismological network. Preliminary location of the hypocenters yield earthquake depths predominantly between 15 and 30 km. Many events registered by the local seismological network have been relocated~10 km west- wards of the previous land-based locations, which might indicate a bias in the existing catalogues. Wide-angle record sections of high quality were obtained, for all profiles shot. Mantle phases over offsets of more than 120 km were recorded by many stations. The pre- liminary velocity depth model derived for a profile striking E-W at 31a S across the subduction zone resolved the lateral transition on the

    The processes that govern magma generation and extraction at subduction zones are not yet well understood. Velocity tomography and earthquake locations from the TUCAN (Tomography Under Costa Rica and Nicaragua) PASSCAL experiment give insight into the geometry and structure of the Central American subduction zone, which exhibits large variations in downgoing plate roughness and dip, volcano locations, and geochemistry over a short distance along the arc. Approximately 14000 P travel times and 11000 S travel times are used in joint Vp, Vp/Vs and hypocenter inversions. The present-day slab geometry is highlighted by contrasts in dip beneath the two arc sections: a near-vertical slab dip beneath the volcanic front in Nicaragua, similar to that indicated by teleseismic hypocenters and a 30° slab dip beneath central Costa Rica, similar to that indicated by a previous local study. In both regions, the intermediate-depth seismic zone is a single layer as thin as 5 km in some areas and no more than 10 to 20 km thick overall. Tomographic images show that throughout Nicaragua and Costa Rica, the slowest mantle velocities appear directly below the volcanic front, indicating likely zones of mantle melting extending 80 to 120 km depth. This region is much larger beneath Nicaragua than beneath Costa Rica, potentially allowing a greater extent of melting. Within the downgoing plate, a low-velocity region is imaged at depths less than 150 km beneath Nicaragua and in the upper 60 km of the slab beneath Costa Rica. This feature may represent a hydrated layer at the top of the downgoing plate, similar to that seen in waveguide studies. Beneath Nicaragua, we also see evidence for a dipping high-velocity region in the mantle wedge beneath Nicaragua extending from 20 to 100 km trenchward of the arc, consistent with results from receiver function analysis and offshore active source tomography. This high-velocity region may serve as an impediment to mantle flow and fluid migration

  2. Manual on sample-based data collection for fisheries assessment : Examples from Viet Nam

    DEFF Research Database (Denmark)

    Sparre, Per Johan

    This manual deals with the practical implementation of a routine data collection programme. This programme is developed through a top-down approach, from the identification of the objectives down to the practical recording and management of data obtained from the fishery. The issues are dealt...... with through both detailed discussion and by using simple examples. These examples are mostly based on situations in tropical fisheries and, in particular, experience has been drawn from developing a data collection programme in Viet Nam. The main questions addressed in the manual are which fisheries data...... to collect, where and when to collect them. Only data collected from commercial marine capture fisheries are considered (data from freshwater fisheries, cultured fish and experimental fisheries are excluded). The methodologies used are mainly appropriate for a tropical developing country with many small...

  5. Primary sarcomas of the central nervous system: UCSF experience (1985-2005

    2007-01-01

    Full Text Available Sarcomas constitute less than 2% of all cancers, and are a highly diverse group of neoplasms. Primary sarcomas of the central nervous system (CNS are even less common, and our experience is limited by lack of studies with sufficient size that can address the challenges in predicting behavior or management. It is critical to recognize the characteristics of these uncommon neoplasms and to develop better predictors for prognosis and behavior.We have conducted a search of the UCSF Department of Pathology and UCSF Cancer Center Registry databases for all primary CNS sarcomas that were diagnosed and treated between 1985 and 2005. Hemangiopericytomas were included, so were the solitary fibrous tumors due to their close association with the former. We excluded all cases of metastatic sarcomas, chordomas, sarcomatoid variants of all neuroepithelial neoplasms, Ewing’s sarcomas and other embryonal tumors. In addition, we have identified all soft tissue sarcomas diagnosed and treated during the same period. There were 43 primary CNS neoplasms that fulfilled the inclusion criteria. At the same time, we identified 1706 sarcomas primary to the soft tissue. Primary CNS sarcomas included 16 hemangiopericytomas, 15 chondrosarcomas, 3 solitary fibrous tumors, 3 osteosarcomas, 2 leiomyosarcomas, 2 undifferentiated sarcomas, 1 histiocytic sarcoma, and 1 fibrosarcoma. There was a distinctly higher frequency of hemangiopericytoma in the CNS compared to soft tissue. In addition, a group of low grade, parasagittal chondrosarcomas were noted for their highly indolent biological behavior. Unlike some previous series, our cohort was devoid of angiosarcoma and malignant fibrous histiocytoma. This study underscores the limitations of single institutional series, and highlights the value of multi-institutional studies to understand and better treat primary CNS sarcomas.

  13. Structure and Dynamics of Fisheries in Nigeria

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The changes that have taken place in Nigerian fisheries are reviewed. Artisanal fishery has continued to dominate the fisheries, contributing over 85% of total fish production. The inland water and coastal seas are fully exploited and the increase in fishery production is not likely. Aquaculture potentials remain untapped as much as deep-sea fisheries. The combined potential of the fisheries resources-freshwater, marine and aquaculture can meet over 90% of the nation's demand for fish. Opportunities for investments, therefore, exist in the various subsectors, especially in the areas of storage, processing and preservation for the capture fishery and fish seed multiplication for aquaculture.

    The simulating experiments of deformation for fresh granite samples from central part of the Jiangnan Belt under a Three Axes Stress Experimental Machine are reported, by which plenty of deformed microstructures from brittle to ductile corresponding to different temperatures and pressures have been obtained. Experiments suggest that additives of fluid (NaCl saturated solution) and setting shear plane for a sample before experiment can lower the temperature and wall pressure and shorten the experimental time from undeformation to mylonitizition. The experimental results provide some important evidence for origin mechanism and formation conditions of natural mylonitic granite.

  15. How fisheries management can benefit from genomics?

    Science.gov (United States)

    Valenzuela-Quiñonez, Fausto

    2016-09-01

    Fisheries genomics is an emerging field that advocates the application of genomic tools to address questions in fisheries management. Genomic approaches bring a new paradigm for fisheries management by making it possible to integrate adaptive diversity to understand fundamental aspects of fisheries resources. Hence, this review is focused on the relevance of genomic approaches to solve fisheries-specific questions. Particularly the detection of adaptive diversity (outlier loci) provides unprecedented opportunity to understand bio-complexity, increased power to trace processed sample origin to allow enforcement and the potential to understand the genetic basis of micro-evolutionary effects of fisheries-induced evolution and climate change. The understanding of adaptive diversity patterns will be the cornerstone of the future links between fisheries and genomics. These studies will help stakeholders anticipate the potential effects of fishing or climate change on the resilience of fisheries stocks; consequently, in the near future, fisheries sciences might integrate evolutionary principles with fisheries management.

Colonizing the smears of the cut catheter tops, there was found a positive finding in 8.9% of femoral and 4.7% of jugular catheters in which the mentioned type of staphylococcal bacteria was prevalent, without statistically significant difference (p = 0.82. In 77% of femoral, 71.4% of jugular and 68.4% of subclavian catheters, there were no complications associated with insertion and manipulation of catheters for hemodialysis and the difference was at the limits of statistical significance (p = 0.06. Conclusion. Unconvincing rate of infections and a smaller percent of serious complications associated with the placement and use of central vein catheters instilled into the femoral vein, indicate that personal experience is sufficient recommendation to convince us that femoral vein does not represent a region with an increased risk for insertion of hemodialysis catheters.

    Large areas of African moist forests are being logged in the context of supposedly sustainable management plans. It remains however controversial whether harvesting a few trees per hectare can be maintained in the long term while preserving other forest services as well. We used a unique 24 year silvicultural experiment, encompassing 10 4 ha plots established in the Central African Republic, to assess the effect of disturbance linked to logging (two to nine trees ha⁻¹ greater than or equal to 80 cm DBH) and thinning (11-41 trees ha⁻¹ greater than or equal to 50 cm DBH) on the structure and dynamics of the forest. Before silvicultural treatments, above-ground biomass (AGB) and timber stock (i.e. the volume of commercial trees greater than or equal to 80 cm DBH) in the plots amounted 374.5 ± 58.2 Mg ha⁻¹ and 79.7 ± 45.9 m³ ha⁻¹, respectively. We found that (i) natural control forest was increasing in AGB (2.58 ± 1.73 Mg dry mass ha⁻¹ yr⁻¹) and decreasing in timber stock (-0.33 ± 1.57 m³ ha⁻¹ yr⁻¹); (ii) the AGB recovered very quickly after logging and thinning, at a rate proportional to the disturbance intensity (mean recovery after 24 years: 144%). Compared with controls, the gain almost doubled in the logged plots (4.82 ± 1.22 Mg ha⁻¹ yr⁻¹) and tripled in the logged + thinned plots (8.03 ± 1.41 Mg ha⁻¹ yr⁻¹); (iii) the timber stock recovered slowly (mean recovery after 24 years: 41%), at a rate of 0.75 ± 0.51 m³ ha⁻¹ yr⁻¹ in the logged plots, and 0.81 ± 0.74 m³ ha⁻¹ yr⁻¹ in the logged + thinned plots. Although thinning significantly increased the gain in biomass, it had no effect on the gain in timber stock. However, thinning did foster the growth and survival of small- and medium-sized timber trees and should have a positive effect over the next felling cycle.

    The microbial contamination of central air conditioning system is one of the important factors that affect the indoor air quality. Actual measurement and analysis were carried out on microbial contamination in central air conditioning system at a venue in Dalian, China. Illumina miseq method was used and three fungal samples of two units were analysed by high throughput sequencing. Results showed that the predominant fungus in air conditioning unit A and B were Candida spp. and Cladosporium spp., and two fungus were further used in the hygrothermal response experiment. Based on the data of Cladosporium in hygrothermal response experiment, this paper used the logistic equation and the Gompertz equation to fit the growth predictive model of Cladosporium genera in different temperature and relative humidity conditions, and the square root model was fitted based on the two environmental factors. In addition, the models were carried on the analysis to verify the accuracy and feasibility of the established model equation.

  14. The influence of hook type, angler experience, and fish size on injury rates and the duration of capture in an Alaskan catch-and-release rainbow trout fishery

    Science.gov (United States)

    Meka, J.M.

    2004-01-01

    Owing to concerns about the high incidence of past hooking injuries in Alagnak River rainbow trout Oncorhynchus mykiss, fish were captured with spin- and fly-fishing gear with barbed and barbless circle and "J" hooks to determine gear types contributing to injury. Landing and hook removal times were measured for a portion of fish captured, and the anatomical hooking location, hooking scar locations, bleeding intensity, angler experience, and fish size were recorded for all captured fish. Approximately 62% of fish captured experienced at least one new hooking injury, and 29% of fish had at least one past hooking injury. Small fish sustained higher new injury and bleeding rates, but large fish had higher past injury rates. Injury rates were higher for barbed J hooks, barbed J hooks took longer to remove, and fish caught by spin-fishing were injured more frequently than fish caught by fly-fishing. Fewer fly-fishing-caught fish were injured using circle hooks, and circle hooks tended to hook fish in only one location, generally in the jaw. Barbed J hooks were more efficient at landing fish, and J hooks were more efficient at landing fish than circle hooks. Novice anglers injured proportionally more fish than experienced anglers, primarily during hook removal. Landing time was positively correlated with fish size, and experienced anglers took longer to land fish than novices because they captured larger fish. These results suggest that a reduction in hooking injuries may be achieved by using circle hooks as an alternative to J hooks and barbless J hooks to reduce injury and handling time, yet catch efficiency for both methods would be reduced. Although fish captured with barbless J hooks and circle hooks had fewer injuries, it is important to note that each hook type also caused significant injury, and angler education is recommended to promote proper hook removal techniques.

  15. Community management of natural resources, agrosilvopastoral and fisheries in the Sierra de Santa Marta, Veracruz, Mexico: a possible alternative to developmental discourse and capitalist globalization?

    Full Text Available This research studies the processes of community natural resources management, agrosilvopastoral and fishery, since the agrarian communalism is presented as a central issue in the contemporary agrarian world with implications for the biocultural heritage management, more in line with socio-economic approaches of the 21st century. Thus, from a qualitative methodology, the advances of the first research offer a vision of communal management of goods: land, pastures, livestock, water, fisheries and ecotourism. The experiments studied in Sierra de Santa Marta of Veracruz in Mexico, through the caseanalysis Project Sierra de Santa Marta, PSSM, show how, starting from an “ecology of knowledge (Santos, 2009, the resources of the jungle have allowed different peasant and/or indigenous communities to survive, avoiding, largely, to resort to emigration. From the theoretical positioning of this work, it would no longer be an alternative development model, but an alternative to development or a post-development

  16. Fisheries-induced disruptive selection.

    Science.gov (United States)

    Landi, Pietro; Hui, Cang; Dieckmann, Ulf

    2015-01-21

    Commercial harvesting is recognized to induce adaptive responses of life-history traits in fish populations, in particular by shifting the age and size at maturation through directional selection. In addition to such evolution of a target stock, the corresponding fishery itself may adapt, in terms of fishing policy, technological progress, fleet dynamics, and adaptive harvest. The aim of this study is to assess how the interplay between natural and artificial selection, in the simplest setting in which a fishery and a target stock coevolve, can lead to disruptive selection, which in turn may cause trait diversification. To this end, we build an eco-evolutionary model for a size-structured population, in which both the stock׳s maturation schedule and the fishery׳s harvest rate are adaptive, while fishing may be subject to a selective policy based on fish size and/or maturity stage. Using numerical bifurcation analysis, we study how the potential for disruptive selection changes with fishing policy, fishing mortality, harvest specialization, life-history tradeoffs associated with early maturation, and other demographic and environmental parameters. We report the following findings. First, fisheries-induced disruptive selection is readily caused by commonly used fishing policies, and occurs even for policies that are not specific for fish size or maturity, provided that the harvest is sufficiently adaptive and large individuals are targeted intensively. Second, disruptive selection is more likely in stocks in which the selective pressure for early maturation is naturally strong, provided life-history tradeoffs are sufficiently consequential. Third, when a fish stock is overexploited, fisheries targeting only large individuals might slightly increase sustainable yield by causing trait diversification (even though the resultant yield always remains lower than the maximum sustainable yield that could be obtained under low fishing mortality, without causing disruptive

    Laparoscopic major hepatectomy is a common procedure that has been reported frequently; however, laparoscopic resection of centrally located tumors involving segments 4, 5, and 8 remains a technically difficult procedure because it requires 2 transection planes and dissection of numerous branches of the hepatic vein and glissonean capsule compared to hemi-hepatectomy. Here, we present 7 cases of totally laparoscopic right anterior sectionectomy (Lap-RAS) and 3 cases of totally laparoscopic central bisectionectomy (Lap-CBS).Between May 2013 and January 2015, 10 totally laparoscopic anatomical resections of centrally located tumors were performed in our institution. The median age of the patients was 54.2 (38-72) years and the median ICG-R15 was 10.4 (3.9-17.4). There were 8 patients with hepatocellular carcinoma (HCC) and 2 with metastatic colorectal cancer. All the HCC patients has the liver function impairment on the degree of Child-Pugh score A.The mean operation time was 330 ± 92.7 minutes with an estimated blood loss of 325 ± 234.5 mL.

    In this paper, we present stylized facts about exchange rate fluctuations and intervention behavior in the Exchange Rate Mechanism I (ERM I), in particular in light of the recent literature on multilateral target zone models. We estimate bilateral exchange rate distributions of the maximum spot rate deviations of six ERM I currencies, explicitly taking the multilateral setting of ERM I into account. In a further analysis, we estimate short-term reaction functions for the central banks of Belg...

    This article addresses two topics. We provide an overview of the National Institutes of Health Mouse Metabolic Phenotyping Center (MMPC) Program. We then discuss some observations we have made during the first eight years of the Vanderbilt MMPC regarding common phenotyping practices. We include specific recommendations to improve phenotyping practices for tests of glucose tolerance and insulin action. We recommend that methods for experiments in vivo be described in manuscripts. We make specific recommendations for data presentation, interpretation, and experimental design for each test. To facilitate and maximize the exchange of scientific information, we suggest that guidelines be developed for methods used to assess glucose tolerance and insulin action in vivo. PMID:19638507

    Biodiverse coastal zones are often areas of intense fishing pressure due to the high relative density of fishing capacity in these nearshore regions. Although overcapacity is one of the central challenges to fisheries sustainability in coastal zones, accurate estimates of fishing pressure in coastal zones are limited, hampering the assessment of the direct and collateral impacts (e.g., habitat degradation, bycatch) of fishing. We compiled a comprehensive database of fishing effort metrics and...

  7. The new institutionalist approaches to health care reform: lessons from reform experiences in Central Europe.

    Science.gov (United States)

    Sitek, Michał

    2010-08-01

    This article discusses the applicability of the new institutionalism to the politics of health care reform in postcommunist Central Europe. The transition to a market economy and democracy after the fall of communism has apparently strengthened the institutional approaches. The differences in performance of transition economies have been critical to the growing understanding of the importance of institutions that foster democracy, provide security of property rights, help enforce contracts, and stimulate entrepreneurship. From a theoretical perspective, however, applying the new institutionalist approaches has been problematic. The transitional health care reform exposes very well some inherent weaknesses of existing analytic frameworks for explaining the nature and mechanisms of institutional change. The postcommunist era in Central Europe has been marked by spectacular and unprecedented radical changes, in which the capitalist system was rebuilt in a short span of time and the institutions of democracy became consolidated. Broad changes to welfare state programs were instituted as well. However, the actual results of the reform processes represent a mix of change and continuity, which is a challenge for the theories of institutional change.

  8. Central Asia: Kyrgyzstan and the learning experience in the design of pastoral institutions.

    Science.gov (United States)

    Kasymov, U; Undeland, A; Dörre, A; Mackinnon, A

    2016-11-01

    The authors analyse the nature of policy development to understand the reasons for institutional change in pasture management in Kyrgyzstan. They use the concept of intentional institutional change, emphasising its incremental nature and the important relationship between belief systems and institutions. The paper explores the relationship between the perceptions and beliefs of policy-makers, the policy interventions they undertake, and the consequences for pastoral migration and practices. The study reveals the gap between the intentions behind such policies and their outcomes, the persistence and importance of pastoral migration, and the learning process that policy-makers undergo. This close look at the development and institutionalisation of new dominant societal beliefs highlights the possible direction of the future development of formal pastoral institutions in Central Asia. Policy-makers should respond better to changes in pastoral mobility and the unsustainable increase in intensified use of natural pastures. Policy-makers must also respond to the growth in conflict over pasture use by becoming more aware of the need for inter-sectoral cooperation. The authors argue that a crucial test for the new formal institutions still lies ahead. The key questions are: whether policy-makers and pasture users can eventually come to hold the same beliefs about what is needed in their society, and what new effective institutions will emerge to define the future of pastoralism in Central Asia.

    Full Text Available This work deals with the analysis and sublimation of all the relevant informations regarding fisheries in Republic of Croatia. This means that there were processed data about freshwater fisheries (farming of freshwater fish and other aquatic organisms, commercial and sports fisheries, marine fisheries (mariculture, commercial fisheries, small–scale fisheries and processing of fish products, import and export of fish and fish products as well as the financial subventions regarding fisheries. The farming of freshwater fish in 2003 is marked by the decrease of production comparing to the past 5 years. Carp is furthermore the most dominant fish species in freshwater fish farming, but it’s percentage is decreasing, and the percentage of the trout is increasing over the years. In addition to the decrease of production, the areas of production are decreasing as well, and now they are the smallest in the past decade — 6,281.97 ha. In 2003 the amount of used food is also decreased, but the amount of used fertilizers and lime is increased, that means it is the biggest in the past decade. This is caused by the bad climate conditions during the summer. Marine fisheries farming (mariculture in 2003 is in a slightly better position then the freshwater fish farming. The production of white fish species, which was reached before few years, is not changing — 2,510 tons, also the farming of oysters is stagnating, but in the past few years the farming of mussels and tuna fish is increasing. The total marine fish catch is 29,102 tons and it is performed over 34,000 km2, comparing to the 2002 it is increased by almost 49.24%. Additional to the increase of the total catch the number of commercial fishermen and fishing vessels is also increased. The number of fisherman which fish for their own consumption without the right to sell fish, that means the small–scale fishermen in 2003 is 13,500. The production of fish and fish products in 2003 is 19,000 tons

  16. A Bioeconomic Analysis of Traditional Fisheries in the Red Sea

    KAUST Repository

    Jin, Di

    2012-06-15

    We undertake a bioeconomic analysis of the aggregate traditional fisheries in the Northern and Central areas of Red Sea off the coast of the Kingdom of Saudi Arabia (KSA). Results of our analysis using a Fox model and the Clarke-Yoshimoto-Pooley (CY&P) estimation procedure suggest that the aggregate traditional fisheries have been overfished since the early 1990s. The estimated stock size in recent years is as low as 6,400 MT, while the estimated stock size associated with the maximum economic yield (MEY) is 19,300 MT. The socially optimal level of fishing effort is about 139,000 days. Thus, the current effort level of 300,000 to 350,000 days constitutes a problem of overfishing. The estimated current total gross revenue from the traditional fisheries is Saudi Rials (SR) 147 million with zero net benefit. If total fishing effort is reduced to the socially optimal level, then we estimate gross revenue would be SR 167 million and the potential net benefit from the KSA Red Sea traditional fisheries could be as large as SR 111 million.

    Full Text Available Thirty-one patients with end-stage renal disease (ESRD were offered continuous ambulatory peritoneal dialysis (CAPD at the Dammam Central Hospital, Dammam, Saudi Arabia over a period of five years. The group included 21 women and 10 men with a mean age of 41.3 ± 17.2 years. The main indication for CAPD was poor or failed vascular access (51.4%. Peritonitis remained the major complication with an overall incidence of 0.62 episode per patient year. Staphylococcus epidermidis was the main causative organism. Therapy with CAPD lasted a mean of 26 ± 7.4 months. Our results, showing good technique survival and low peritonitis rate, suggest that CAPD should be promoted to become a full arm of the integrated care of ESRD in Saudi Arabia.

    2016-11-01

    Relapsing polychondritis (RP) is an autoimmune disorder characterized by inflammation in cartilaginous structures including the ears, noses, peripheral joints, and tracheobronchial tree. It rarely involves the central nervous system (CNS) but diagnosis of CNS complication of RP is challenging because it can present with varying clinical features. Herein we report 3 cases of relapsing polychondritis involving CNS with distinct manifestations and clinical courses. The first patient presented with rhombencephalitis resulting in brain edema and death. The second patient had acute cognitive dysfunction due to limbic encephalitis. He was treated with steroid pulse therapy and recovered without sequelae. The third patient suffered aseptic meningitis that presented as dementia, which was refractory to steroid and immune suppressive agents. We also reviewed literature on CNS complications of RP.

    2005-06-01

    Dental services in sports competitions in the Games sponsored by the International Olympic Committee are mandatory. In every Central American, Pan American and Olympic Summer Games, as well as Winter Games, the Organizing Committee has to take all the necessary measures to assure dental services to all competitors. In all Olympic villages, as part of the medical services, a dental clinic is set up to treat any dental emergency that may arise during the Games. Almost every participating country in the Games has its own medical team and some may include a dentist. The major responsibilities of the team dentist as a member of the national sports delegation include: (i) education of the sports delegation about different oral and dental diseases and the illustration of possible problems that athletes or other personnel may encounter during the Games, (ii) adequate training and management of orofacial trauma during the competition, (iii) knowledge about the rules and regulations of the specific sport that the dentist is working, (iv) understanding of the anti-doping control regulations and procedures, (v) necessary skills to fabricate a custom-made and properly fitted mouth guard to all participants in contact or collision sports of the delegation. This study illustrates the dental services and occurrence of orofacial injury at the Central American and Caribbean Sports Games of the Puerto Rican Delegation for the past 20 years. A total of 2107 participants made up the six different delegations at these Games. Of these 279 or 13.2% were seen for different dental conditions. The incidence of acute or emergency orofacial conditions was 18 cases or 6% of the total participants. The most frequent injury was lip contusion with four cases and the sport that experienced more injuries was basketball with three cases.

  1. Wide-Angle Seismic Experiment Across the Oeste Fault Zone, Central Andes, Northern Chile.

    Lorenzo, J. M.; Yáñez, G. A.; Vera, E. E.; Sepúlveda, J.

    2008-12-01

    From December 6-21, 2007, we conducted a 3-component, radio-telemetric, seismic survey along a ~ 15-km wide E-W transect in the Central Andes, at a latitude of ~ 22.41° S, centered north of the city of Calama (68.9° W), Chile. The study area is sandwiched between the Central Depression in the west and the Andean Western Cordillera of Chile. Recording stations, nominally spaced at intervals of either 125 or 250 m collected up to 3.5 s of refracted seismic arrivals at maximum source-receiver offsets exceeding 15 km. Ten shothole sources, spaced 2-6 km apart focused energy on the shallow (0-3 km), crustal, Paleogene-age structures. Preliminary, tomographic inversions of refracted first arrivals show the top of a shallow ( 600 km), strike-slip fault zone known as the Oeste fault. Turning ray densities suggest the base of the overlying velocity gradient unit (VP, 2-4 km/s) dips inwardly from both east and west directions toward the Oeste fault to depths of almost 1 km. Plate reorganization commencing at least by the latter half of the Oligocene led from oblique to more orthogonal convergence between the South American and the Nazca (Farallon) Plates. We interpret previously mapped, older, minor faults as being generated within the right-lateral, orogen-parallel, Oeste strike-slip fault zone, and postdated by Neogene, N-S striking thrust faults. In this context we also interpret that the spatial distribution of velocity units requires an period of extensional activity that may (1) postdate the transpressional strike slip fault activity of the Neogene, (2) be related to a later releasing bend through the translation and interaction of rigid blocks hidden at depth or even (3) be the consequence of inelastic failure from the result of flexural loading.

    Total allowable catch (TAC) management has in many fisheries, especially mixed fisheries, failed to meet conservation objectives. For instance, for the Faroe Plateau mixed demersal fisheries, the TAC system failed to achieve the objective of an average annual fishing mortality of 0.45 for the three...... gadoid stocks cod (Gadus morhua), haddock (Melanogrammus aeglefinus), and saithe (Pollachius virens). Therefore, in 1996, an effort-regulation system with individual transferable effort quotas was introduced to manage the fisheries. Experience has shown that effort management without additional stock......-specific measures may not be appropriate for such fisheries. A management strategy evaluation model was developed to compare an effort-management system based on the Faroese example with a TAC system as currently applied in EU fisheries. Results show that when stocks are considered in isolation, a total allowable...

    The highly productive fisheries of Alaska are located in seas projected to experience strong global change, including rapid transitions in temperature and ocean acidification-driven changes in pH and other chemical parameters. Many of the marine organisms that are most intensely affected by ocean acidification (OA) contribute substantially to the state's commercial fisheries and traditional subsistence way of life. Prior studies of OA's potential impacts on human communities have focused only on possible direct economic losses from specific scenarios of human dependence on commercial harvests and damages to marine species. However, other economic and social impacts, such as changes in food security or livelihoods, are also likely to result from climate change. This study evaluates patterns of dependence on marine resources within Alaska that could be negatively impacted by OA and current community characteristics to assess the potential risk to the fishery sector from OA. Here, we used a risk assessment framework based on one developed by the Intergovernmental Panel on Climate Change to analyze earth-system global ocean model hindcasts and projections of ocean chemistry, fisheries harvest data, and demographic information. The fisheries examined were: shellfish, salmon and other finfish. The final index incorporates all of these data to compare overall risk among Alaska's federally designated census areas. The analysis showed that regions in southeast and southwest Alaska that are highly reliant on fishery harvests and have relatively lower incomes and employment alternatives likely face the highest risk from OA. Although this study is an intermediate step toward our full understanding, the results presented here show that OA merits consideration in policy planning, as it may represent another challenge to Alaskan communities, some of which are already under acute socio-economic strains.

  5. Production cavity and central optics for a light shining through a wall experiment

    The unexplained nature of dark matter and dark energy is a prominent reason for investigating physics beyond the standard model of particle physics (SM). Some extensions of the SM propose weakly interacting slim particles (WISPs). In an attempt to prove the existence of these particles, Light shining through the wall (LSW) experiments explore a very weak coupling between WISPs and photons (and viceversa). LSW experiments employ high-power lasers that provide a well defined flux of photons for the WISP-Photon conversion. The ALPS-I experiment at DESY in Hamburg was the first successful experiment with a high finesse optical resonator to enhance the laser power in a strong magnetic field in order to increase the photon to WISP conversion probability. The ALPS-II experimental concept adds a second optical cavity to also increase the reconversion probability. Both cavities are separated by a wall, amplify light at 1064 nm and share a common optical axis. Operating these two cavities inside 20 straightened HERA superconducting dipole magnets and using a transition edge sensor (TES) as a single photon detector will make the ALPS-II experiment almost three orders of magnitude more sensitive than its predecessor. Since photons, originating from reconverted WISPs in the regeneration cavity (RC) have 1064 nm wavelengths, the RC has to be locked to the production cavity (PC) with light of a different wavelength. Therefore frequency doubled PCs light will be used to lock the RC. This 532 nm light shall not arrive at the TES to prevent background noise. To achieve this, an optical attenuation system for wavelengths different from 1064 nm is required. In my thesis, the required attenuation was estimated and an optical setup was proposed and constructed and tested. It attenuates green photons by a factor of of 10{sup -18} and transmits 85% of the infrared photons. Furthermore the high finesse production cavity of ALPS-IIa was set up and characterized during this thesis. The PC

    What would extensive fishery reform look like? In addition, what would be the benefits and trade-offs of implementing alternative approaches to fisheries management on a worldwide scale? To find out, we assembled the largest-of-its-kind database and coupled it to state-of-the-art bioeconomic models for more than 4,500 fisheries around the world. We find that, in nearly every country of the world, fishery recovery would simultaneously drive increases in food provision, fishery profits, and fis...

    Full Text Available Background Magnetic resonance imaging (MRI is gradually becoming more common for thorough visualization of the fetus than ultrasound (US, especially for neurological anomalies, which are the most common indications for fetal MRI and are a matter of concern for both families and society. Objectives We investigated fetal MRIs carried out in our center for frequency of central nervous system anomalies. This is the first such report in southern Iran. Materials and Methods One hundred and seven (107 pregnant women with suspicious fetal anomalies in prenatal ultrasound entered a cross-sectional retrospective study from 2011 to 2013. A 1.5 T Siemens Avanto scanner was employed for sequences, including T2 HASTE and Trufisp images in axial, coronal, and sagittal planes to mother’s body, T2 HASTE and Trufisp relative to the specific fetal body part being evaluated, and T1 flash images in at least one plane based on clinical indication. We investigated any abnormality in the central nervous system and performed descriptive analysis to achieve index of frequency. Results Mean gestational age ± standard deviation (SD for fetuses was 25.54 ± 5.22 weeks, and mean maternal age ± SD was 28.38 ± 5.80 years Eighty out of 107 (74.7% patients who were referred with initial impression of borderline ventriculomegaly.

  13. Baryon-antibaryon asymmetry in central rapidity region at LHC with the ALICE experiment

    CERN Document Server

    Broz, Michal

    The Large Hadron Collider (LHC) provided the first proton-proton collisions in the period of November-December 2009. Since then, a large data sample has been recorded by all LHC experiments. This event sample allows us to study more and more exotic particles and events. The ALICE (A Large Ion Collider Experiment) experiment, though designed primarily to study heavy ion collisions, has a rich proton-proton physics program. The characteristic features of ALICE are its very low-momentum cut-off, the low material budget and the excellent particle identification (PID) and vertexing capabilities. In this thesis, I discuss the results from the analysis of proton-proton collisions at the different LHC energies (√s = 900 GeV, 2.76 TeV and 7 TeV). I concentrate on the antibaryon-to-baryon ratio study which is of great importance for description of baryon number transport and it can allow to determine the carrier of the baryon number as well as to give an information on baryon structure itself. In particular, the mult...

    Primary production must constrain the amount of fish and invertebrates available to expanding fisheries; however the degree of limitation has only been demonstrated at regional scales to date. Here we show that phytoplanktonic primary production, estimated from an ocean-colour satellite (SeaWiFS), is related to global fisheries catches at the scale of Large Marine Ecosystems, while accounting for temperature and ecological factors such as ecosystem size and type, species richness, animal body size, and the degree and nature of fisheries exploitation. Indeed we show that global fisheries catches since 1950 have been increasingly constrained by the amount of primary production. The primary production appropriated by current global fisheries is 17-112% higher than that appropriated by sustainable fisheries. Global primary production appears to be declining, in some part due to climate variability and change, with consequences for the near future fisheries catches.

    This article analyses an ongoing planning process in Greenlandic fisheries governance aiming to reform the coastal Greenland halibut fishery. It examines the way certain truths about this fishery and the need for reform are produced up to and in the final policy document ‘regulation concerning...... the coastal fishery for Greenland halibut’. Findings highlight the way the small-scale Greenland halibut fishery system becomes a particular governance problem with respect to particular contextual meanings of sustainability and long-term planning. The article then examines whether this governance problem...... could also be understood as primarily a problem to a certain ‘governmentality’ mode of governance. Whereas some fishery studies document how governmentality modes of governance in fisheries succeeds in transforming subjectivities, this study offers a view into the process that might go before successful...

  17. RECRUITMENT AND RECRUITMENT MODELS IN FISHERY SCIENCE

    Directory of Open Access Journals (Sweden)

    Merica Slišković

    2006-04-01

    Full Text Available Recruitment and growth of individuals bring the most to enlargement of fish stock biomass. Recruitment can be independent on stock size during the development of the fishery, but experience has showed that many fisheries have come to the point when recruitment decreases due to over fishing. Large parental stock does not give large number of juveniles because large number of individuals influences survival of juveniles (competition for food. In period between 1984 and 1987 this phenomenon was recorded in sardine population in the Adriatic Sea, when large biomass of parental stock resulted in twice less recruitment. In the period between 1993 and 2000 there was no significant recruitment of the sardine population in the Adriatic Sea and it reflected on biomass of the sardine. Large recruitment was recorded in 2001 and 2002. There are numerous mathematical models which give relation between stock and recruitment. Beverton–Holt’s and Ricker’s models are usually used. Beverton–Holt’s model assumes that recruitment depends on the density of population. Ricker’s model is based on assumption that all resources are evenly distributed among the individuals; therefore the rise in density causes the exhaustion of resources. This model is suitable for species as the sardine, which migrates in the breeding area.

    The authors conducted a community based, cross-sectional study to describe the prevalence of intimate partner violence (IPV) by husbands and the association between wives' attitudes toward gender roles and their experience of IPV in Central Province, Sri Lanka. This article included a representative sample of 624 wives between 15 and 49 years of age and examined the prevalence of physical, psychological, and sexual abuse. Then, using multivariate logistic regression analysis, the authors examined the association between wives' attitudes toward gender roles and IPV. Of the 624 wives, 36% had experienced at least one episode of physical, psychological, or sexual abuse by their husbands during their life time (ever abuse), and 19% had experienced such abuse during the past 12 months (current abuse). The wives were less likely to experience current abuse by husbands if they believed that "outsiders should not intervene to protect abused wives." They were more likely to experience ever and current isolated psychological abuse by husbands if they did not believe that "a good wife always obeys her husband." This study suggests that the prevalence of IPV is high in Sri Lanka. Although several published studies on IPV suggest that traditional gender role attitudes tend to increase women's vulnerability to IPV, this study suggests that in Sri Lanka, the wives who respect cultural norms tend to experience less IPV by husbands.

    Prehospital emergency medicine (PHEM) is a recently recognised subspecialty of emergency medicine, and anaesthetics, intensive care and acute medicine, in the UK, and yet it receives little to no mention in many undergraduate medical curricula. However, there is growing interest in PHEM among medical students and junior doctors. Several programmes are in existence across the UK that serve to provide teaching and exposure of prehospital care to medical students and junior doctors. However, relatively few students are able to gain significant first-hand experience of treating patients in the prehospital phase. In this short report, we discuss our experience of launching the student first responder (SFR) scheme across three counties in the Thames Valley. Medical students are trained by the regional ambulance service and respond to life-threatening medical emergencies in an ambulance response vehicle. The scheme is likely to benefit the ambulance service by providing a wider pool of trained volunteer first responders able to attend to emergency calls, to benefit patients by providing a quick response at their time of need, and to benefit medical students by providing first-hand experience of medical emergencies in the community. In its first 15 months of operation, SFRs were dispatched to 343 incidents. This scheme can serve as a training model for other ambulance services and medical schools across the UK.

    We integrated satellite-tracking data from black-footed albatrosses (Phoebastria nigripes; n = 7) and Laysan albatrosses captured in Alaska (Phoebastria immutabilis; n = 18) with data on fishing effort and distribution from commercial fisheries in the North Pacific in order to assess potential risk from bycatch. Albatrosses were satellite-tagged at-sea in the Central Aleutian Islands, Alaska, and tracked during the post-breeding season, July-October 2005 and 2006. In Alaskan waters, fishing effort occurred almost exclusively within continental shelf and slope waters. Potential fishery interaction for black-footed albatrosses, which most often frequented shelf-slope waters, was greatest with sablefish (Anoplopoma fimbria) longline and pot fisheries and with the Pacific halibut (Hippoglossus stenolepsis) longline fishery. In contrast, Laysan albatrosses spent as much time over oceanic waters beyond the continental shelf and slope, thereby overlapping less with fisheries in Alaska than black-footed albatrosses. Regionally, Laysan albatrosses had the greatest potential fishery interaction with the Atka mackerel (Pleurogrammus monopterygius) trawl fishery in the Western Aleutian Islands and the sablefish pot fishery in the Central Aleutian Islands. Black-footed albatrosses ranged further beyond Alaskan waters than Laysan albatrosses, overlapping west coast Canada fisheries and pelagic longline fisheries in the subarctic transition domain; Laysan albatrosses remained north of these pelagic fisheries. Due to inter-specific differences in oceanic distribution and habitat use, the overlap of fisheries with the post-breeding distribution of black-footed albatrosses is greater than that for Laysan albatrosses, highlighting inter-specific differences in potential vulnerability to bycatch and risk of population-level impacts from fisheries. ?? 2008 Elsevier Ltd.

    Background We characterized the incidence of central nervous system (CNS) involvement, risk factors and outcome in a large single institution dataset of peripheral T-cell lymphoma (PTCL). Methods Retrospective review of the PTCL database at Memorial Sloan Kettering Cancer Center. We identified 231 patients with any subtype of PTCL between 1994-2011 with a minimum six months of follow-up or an event defined as relapse or death. Results Histologies included peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS) (31.6%), angioimmunoblastic (16.9%), anaplastic large cell lymphoma (ALCL), ALK- (12.1%), ALCL, ALK + (6.1%), extranodal NK/T-cell lymphoma (7.4%), adult T-cell leukemia/lymphoma (ATLL) (7.4%), and transformed mycosis fungoides (8.7%). Seventeen patients had CNS disease (7%). Fifteen had CNS involvement with PTCL and two had diffuse large B-cell lymphoma and glioblastoma. Median time to CNS involvement was 3.44 months (0.16-103.1). CNS prophylaxis was given to 24 patients (primarily intrathecal methotrexate). Rates of CNS involvement were not different in patients who received prophylaxis. Univariate analysis identified stage III-IV, bone marrow involvement, >1 extranodal site and ATLL as risk factors for CNS disease. On multivariate analysis, >1 extranodal site and international prognostic index (IPI) ≥ 3 were predictive for CNS involvement. The median survival of patients with CNS involvement was 2.63 months (0.10-75). Conclusions Despite high relapse rates, PTCL, except ATLL, carries a low risk of CNS involvement. Prognosis with CNS involvement is poor and risk factors include: >1 extra nodal site and IPI ≥3.

    Primary central nervous system (CNS) germ cell tumors (GCTs) are a rare heterogeneous group of lesions, which the clinicopathological features have a marked degree of heterogeneity comparing with that of gonadal GCTs. Accurately diagnosing CNS GCTs might be extremely difficult and requires immunohistochemical verification. This study was to investigate the biological feature of CNS GCTs and diagnostic value of immunohistochemical markers OCT3/4, C-kit, PLAP, and CD30 in CNS GCTs. A retrospective study was performed on 34 patients with CNS germ cell tumors between 1990 and 2014. 34 CNS GCTs account for 9.2% of all primary CNS neoplasms. The sellar region (35.3%) and pineal gland (17.6%) were the most common sites of intracranial GCTs. Hydrocephalus (82.4%) and diplopia (46.9%) were the two most common clinical presentations. The most common histological subtypes were germinoma (67.6%). PLAP, c-kit, OCT3/4 were highly expressed in gernimomas. CD30 and CK AE1/3 stainings were positive in embryonal carcinoma. Yolk sac tumor component showed positive staining for AFP and CK AE1/3. β-HCG staining was positive in choriocarcinoma and STGC. Patients with mature teratomas and germinomas had a better prognosis (a 5-year survival rate) than those with embryonal carcinoma and choriocarcinoma (a 5-year survival rates were 0). Our finding suggest that the incidences of primary CNS GCTs are higher in South China than in the West, but mixed GCTs are uncommon in our study. The judicious use of a panel of selected markers is helpful in diagnosing and predicting the prognosis for CNS GCTs.

    Patients with progressive primary brain tumors (PBT) are attracted to promising new treatments, even prior to convincing data. Anti-PD1 immunotherapies have been in the spotlight since publication of groundbreaking results for metastatic melanoma with pembrolizumab (PBL). Our objective was to report on the response and toxicity of PBL in patients with advanced PBT. We retrospectively reviewed the charts of 22 patients (17 adults and 5 children) with recurrent central nervous system tumors treated with PBL. We analyzed prior antineoplastic therapies, steroid usage, and outcomes. Patients received a median of two neoplastic therapies prior to PBL, and a median of three infusions of PBL in adults and four in children. Twelve patients (9 adults and 3 children) started PBL on steroids (median dose in adults 4 mg; range 2-8, and in children 1.5 mg, range 0.5-4) and five patients received steroids later during PBL treatment. Twelve patients (10 adults and 2 children) received concomitant bevacizumab with PBL. Side effects were minimal. All patients showed progressive tumor growth during therapy. Median OS from the start of PBL was 2.6 months in adults and 3.2 months in children. Two GB patients underwent tumor resection following treatment with PBL. Tumor-lymphocytic response in these cases was unremarkable, and PD-L1 immuno-staining was negative. In this series of 22 patients with recurrent primary brain tumors, PBL showed no clinical or histologic efficacy. We do not recommend further use of PBL for recurrent PBT unless convincing prospective clinical trial data are published.

    Its peripheral vein puncture point, safe insertion procedure and high rate of success have made the peripherally inserted central catheter (PICC) a particularly suitable medical device for cancer patients who require long-term intravenous chemotherapy. PICC can help avoid the pain of repeat punctures as well as reduce incidence of cytotoxic drug extravasation-induced phlebitis and tissue necrosis. With PICC, patient activity is not limited, which improves quality of life. This paper reported on complications and subsequent nursing care provided to 400 cancer patients who received PICC in our center between September 2007 and October 2008. A total of 395 cases had successful PICC insertion on the first attempt and 5 cases achieved success immediately following the second insertion attempt (overall success rate: 98.8%). The average catheter dwell-in time was 122 days (range 2-350 days), during which time no patient required repeat puncture. During the insertion process, arrhythmia occurred in 1.5% (6/400), difficult catheter propelling in 3.75% (15/400), and excessive oozing of blood in 0.3% (1/400) of subjects. During the catheter dwell-in period, sensitizing dermatitis occurred in 8% (38/400), mechanical phlebitis in 7.5% (30/400), catheter occlusion in 9.5% (38/400) (including 2% [8/400] complete and 7.5% [30/400] partial occlusions), catheter associated hematogenous infection in 3% (12/400) and venous thrombosis in 2% (8/400) of subjects. All complications were well controlled with active and effective management. In conclusion, the safety of PICC can be maximized and complications reduced when nurses fully evaluate patients prior to their operation, strictly adhere to PICC operating guidelines, detect complications early, and manage problems promptly.

    Lake Outburst Floods can evolve from complex process chains like avalanches of rock or ice that produce flood waves in a lake which may overtop and eventually breach glacial, morainic, landslide, or artificial dams. Rising lake levels can lead to progressive incision and destabilization of a dam, to enhanced ground water flow (piping), or even to hydrostatic failure of ice dams which can cause sudden outflow of accumulated water. These events often have a highly destructive potential because a large amount of water is released in a short time, with a high capacity to erode loose debris, leading to a powerful debris flow with a long travel distance. The best-known example of a lake outburst flood is the Vajont event (Northern Italy, 1963), where a landslide rushed into an artificial lake which spilled over and caused a flood leading to almost 2000 fatalities. Hazards from the failure of landslide dams are often (not always) fairly manageable: most breaches occur in the first few days or weeks after the landslide event and the rapid construction of a spillway - though problematic - has solved some hazardous situations (e.g. in the case of Hattian landslide in 2005 in Pakistan). Older dams, like Usoi dam (Lake Sarez) in Tajikistan, are usually fairly stable, though landsildes into the lakes may create floodwaves overtopping and eventually weakening the dams. The analysis and the mitigation of glacial lake outburst flood (GLOF) hazard remains a challenge. A number of GLOFs resulting in fatalities and severe damage have occurred during the previous decades, particularly in the Himalayas and in the mountains of Central Asia (Pamir, Tien Shan). The source area is usually far away from the area of impact and events occur at very long intervals or as singularities, so that the population at risk is usually not prepared. Even though potentially hazardous lakes can be identified relatively easily with remote sensing and field work, modeling and predicting of GLOFs (and also

    Full Text Available Background: Promotion of birth preparedness and raising awareness of potential complications is one of the main strategies to enhance the timely utilisation of skilled care at birth and overcome barriers to accessing care during emergencies. Objective: This study aimed to investigate factors associated with birth preparedness in three districts of eastern central Uganda. Design: This was a cross-sectional baseline study involving 2,010 women from Iganga [community health worker (CHW strategy], Buyende (vouchers for transport and services, and Luuka (standard care districts who had delivered within the past 12 months. ‘Birth prepared’ was defined as women who had taken all of the following three key actions at least 1 week prior to the delivery: 1 chosen where to deliver from; 2 saved money for transport and hospital costs; and 3 bought key birth materials (a clean instrument to cut the cord, a clean thread to tie the cord, cover sheet, and gloves. Logistical regression was performed to assess the association of various independent variables with birth preparedness. Results: Only about 25% of respondents took all three actions relating to preparing for childbirth, but discrete actions (e.g. financial savings and identification of place to deliver were taken by 75% of respondents. Variables associated with being prepared for birth were: having four antenatal care (ANC visits [adjusted odds ratio (ORA=1.42; 95% confidence interval (CI 1.10–1.83], attendance of ANC during the first (ORA=1.94; 95% CI 1.09–3.44 or second trimester (ORA=1.87; 95% CI 1.09–3.22, and counselling on danger signs during pregnancy or on place of referral (ORA=2.07; 95% CI 1.57–2.74. Other associated variables included being accompanied by one's husband to the place of delivery (ORA=1.47; 95% CI 1.15–1.89, higher socio-economic status (ORA=2.04; 95% CI 1.38–3.01, and having a regular income (ORA=1.83; 95% CI 1.20–2.79.

    Data from 4,713 fisheries worldwide, representing 78% of global reported fish catch, are analyzed to estimate the status, trends, and benefits of alternative approaches to recovering depleted fisheries. For each fishery, we estimate current biological status and forecast the impacts of contrasting management regimes on catch, profit, and biomass of fish in the sea. We estimate unique recovery targets and trajectories for each fishery, calculate the year-by-year effects of alternative recovery approaches, and model how alternative institutional reforms affect recovery outcomes. Current status is highly heterogeneous—the median fishery is in poor health (overfished, with further overfishing occurring), although 32% of fisheries are in good biological, although not necessarily economic, condition. Our business-as-usual scenario projects further divergence and continued collapse for many of the world’s fisheries. Applying sound management reforms to global fisheries in our dataset could generate annual increases exceeding 16 million metric tons (MMT) in catch, $53 billion in profit, and 619 MMT in biomass relative to business as usual. We also find that, with appropriate reforms, recovery can happen quickly, with the median fishery taking under 10 y to reach recovery targets. Our results show that commonsense reforms to fishery management would dramatically improve overall fish abundance while increasing food security and profits. PMID:27035953

    Background. Decentralization of care and treatment for HIV infection in Africa makes services available in local health facilities. Decentralization has been associated with improved retention and comparable or superior treatment outcomes, but patient experiences are not well understood. Methods. We conducted a qualitative study of patient experiences in decentralized HIV care in Plateau State, north central Nigeria. Five decentralized care sites in the Plateau State Decentralization Initiative were purposefully selected. Ninety-three patients and 16 providers at these sites participated in individual interviews and focus groups. Data collection activities were audio-recorded and transcribed. Transcripts were inductively content analyzed to derive descriptive categories representing patient experiences of decentralized care. Results. Patient participants in this study experienced the transition to decentralized care as a series of “trade-offs.” Advantages cited included saving time and money on travel to clinic visits, avoiding dangers on the road, and the “family-like atmosphere” found in some decentralized clinics. Disadvantages were loss of access to ancillary services, reduced opportunities for interaction with providers, and increased risk of disclosure. Participants preferred decentralized services overall. Conclusion. Difficulty and cost of travel remain a fundamental barrier to accessing HIV care outside urban centers, suggesting increased availability of community-based services will be enthusiastically received.

    A combination of fisheries dependent and independent data was used to assess the vulnerability of the oceanic whitetip shark to pelagic longline fisheries. The Brazilian tuna longline fleet, operating in the equatorial and southwestern Atlantic, is used as a case study. Fisheries dependent data include information from logbooks (from 1999 to 2011) and on-board observers (2004 to 2010), totaling 65,277 pelagic longline sets. Fisheries independent data were obtained from 8 oceanic whitetip sharks tagged with pop-up satellite archival tags in the area where longline fleet operated. Deployment periods varied from 60 to 178 days between 2010 and 2012. Tagging and pop-up sites were relatively close to each other, although individuals tended to travel long distances before returning to the tagging area. Some degree of site fidelity was observed. High utilization hotspots of tagged sharks fell inside the area under strongest fishing pressure. Despite the small sample size, a positive correlation between tag recorded information and catch data was detected. All sharks exhibited a strong preference for the warm and shallow waters of the mixed layer, spending on average more than 70% of the time above the thermocline and 95% above 120 m. Results indicate that the removal of shallow hooks on longline gear might be an efficient mitigation measure to reduce the bycatch of this pelagic shark species. The work also highlights the potential of tagging experiments to provide essential information for the development of spatio-temporal management measures.

  15. Role of genetics in adapting forests under climate change: lessons learned from common garden experiments in central Europe

    Adaptive management aiming at reducing vulnerability and enhancing the resilience of forested ecosystems is a key to preserving the potential of forests to provide multiple ecosystem services under climate change. Planting alternative or non native tree species adapted to future conditions and also utilizing the genetic variation within tree species has also been suggested as an important adaptive management strategy under climate change. Therefore, knowledge on suitable provenances/populations is a key issue. Provenance trial experiments, where several populations of a species are planted in a particular climate or throughout an appropriate climatic gradient offers a great opportunity to understand adaptive genetic variation within a tree species. These trials were primarily established, for identifying populations with desired growth and fitness characteristics. Due to the increasing interest in climate change, such trials were revisited to understand the relation between growth performance and climate and to recommend suitable populations for future conditions. Here we present the lessons learned from provenance trials of Norway spruce and Douglas -fir in central Europe. With data from provenance trials planted across a wide range of environmental conditions in central Europe we developed multivariate models, Universal Response Functions (URFs). The URFs predict growth performance as a function of climate of planting locations (i.e. environmental factors) and provenance/ population origin (i.e. genetic factors). The flexibility of the URFs as a decision making tool is remarkable. The model can be used as to identify suitable planting material for a give site, and vice versa and also as a species distribution model (SDM) with integrated genetic variation. Under current and climate change scenarios, the URFs were applied to predict populations with higher growth performance in central Europe and also as species distribution models for Douglas-fir (Pseudotsuga

    During the RV SONNE cruise 161 Leg 1 to 5 (October 2001 to January 2002) Sub- duction Processes Off Chile (SPOC) have been investigated using a multi-disciplinary geoscientific approach. Here we report first results of multi channel seismic (MCS) experiments and high-resolution swath bathymetry data from Leg 3, south of Val- paraiso. 24 MCS profiles with a total length of 3670 km were run between 36 S to 4020' S, providing a detailed view of the structures related to the subduction of the Nazca Plate under the Chile Margin. The oceanic crust of the Nazca Plate shows at least three sets of structural trends associated with the Mocha and Valdivia Fractures Zones, the spreading lineations and subduction related horst and graben structures. In the study area the trench is filled with well stratified turbidites up to 2 seconds TWT thick. Along the trench axis a turbidite channel exceeding 80 m relief exists. Several large deep sea fan complexes are developed at the slope toe. Their distributary canyons cut deep into the slope and shelf and can be traced back to major river mouths. The deformation front is coincident with the slope toe; compressional structures of the trench fill are uncommon. The deformation front is curved and offset along strike, caused presumably by collision and indentation of structures of the Nazca Plate. The most remarkable features of the MCS - profiles, yet, are the only very rudimentary developed modern accretionary prism as well as the high variability of the lower slope angles. Lower slope angles locally exceed 10. The continental crust extends seawards to the middle slope and acts as a backstop. Several profiles reveal landward dipping reflectors above the downgoing slab, possibly depicting a subduction channel beneath the slope. Thus, the geometry of the subduction units U a young thick trench fill, only rudimental frontal accretion and a subduction channel U argues for subduction of the bulk of the sediments.

    Latest fisheries directives propose adopting an ecosystem approach to manage fisheries \\citep{FAO-EAFM}. Such an approach aims to protect important ecosystems based on the principle that healthy ecosystems produce more and thus enhance sustainability. Unfortunately, quantifying the importance of an ecosystem is a difficult task to do due the immense number of interactions involved in marine systems. This PhD dissertation relies on the fact that good fisheries distribution maps could play ...

    Abstract In fisheries, alleviating poverty sometimes requires strategies that are inherently in conflict. When aiming to develop a fishery as a means to reduce poverty, its common pool resource basis might be undermined, resulting in greater poverty. But poverty in fisheries is also linked to, or a part of deeper social issues and processes, for instance, the marginalization and exclusion of certain communities. Poverty also has many factors— income, health, literacy, gender, power, sec...

    Previous studies based on Life Cycle Assessment (LCA) in Denmark and Sweden have shown that the fishery is the environmental "hot spot" in the life cycle of fish products. Within the fishery, fuel consumption is one of the most important factors addressed by LCA. The present study reveals...... that there are great differences in the fuel consumption between fisheries targeting ground or shellfish and those targeting pelagic or industrial fish....

    Central venous access device (CVAD) insertion is one of the most common procedures performed on paediatric haemophilia patients. There are no clear guidelines outlining the optimal dosing schedule of factor VIII (FVIII) and duration of treatment required to achieve adequate haemostasis during and after surgery. In this article, we describe the experience at McMaster Children's Hospital using FVIII replacement therapy in 15 children with severe haemophilia A during the course of 7 years. This is a retrospective institutional chart review. Patients between 0 and 18 years of age with severe haemophilia A that underwent CVAD insertion at McMaster Children's Hospital in Hamilton, Ontario, from 2004 to 2010, were identified and charts were reviewed. A total of 15 CVAD insertion surgeries were reviewed. The total average preoperative dose of FVIII was 93.5 IU/kg (range: 53.7-145.4 IU/kg). The total average postoperative dose was 818.7 IU/kg (range: 441-1258 IU/kg). The total perioperative dose was 912.2 IU/kg (range: 495.2-1349 IU/kg). The current study attempts to describe the experience at McMaster Children's Hospital for CVAD insertion surgeries, the average factor dose administered has decreased during the years. These results may be of help in the development of optimal treatment schedules.

  20. Connectivity of a large embayment and coastal fishery: spawning aggregations in one bay source local and broad-scale fishery replenishment.

    Science.gov (United States)

    Hamer, P A; Acevedo, S; Jenkins, G P; Newman, A

    2011-04-01

    Ichthyoplankton sampling and otolith chemistry were used to determine the importance of transient spawning aggregations of snapper Chrysophrys auratus (Sparidae) in a large embayment, Port Phillip Bay (PPB), Australia, as a source of local and broad-scale fishery replenishment. Ichthyoplankton sampling across five spawning seasons within PPB, across the narrow entrance to the bay and in adjacent coastal waters, indicated that although spawning may occur in coastal waters, the spawning aggregations within the bay were the primary source of larval recruitment to the bay. Otolith chemical signatures previously characterized for 0+ year C. auratus of two cohorts (2000 and 2001) were used as the baseline signatures to quantify the contribution that fish derived from reproduction in PPB make to fishery replenishment. Sampling of these cohorts over a 5 year period at various widely dispersed fishery regions, combined with maximum likelihood analyses of the chemistry of the 0+ year otolith portions of these older fish, indicated that C. auratus of 1 to 3+ years of age displayed both local residency and broad-scale emigration from PPB to populate coastal waters and an adjacent bay (Western Port). While the PPB fishery was consistently dominated (>70%) by locally derived fish irrespective of cohort or age, the contribution of fish that had originated from PPB to distant populations increased with age. At 4 to 5+ years of age, when C. auratus mature and fully recruit to the fishery, populations of both cohorts across the entire central and western Victorian fishery, including two major embayments and c. 800 km of coastal waters, were dominated (>70%) by fish that had originated from the spawning aggregations and nursery habitat within PPB. Dependence of this broadly dispersed fishery on replenishment from heavily targeted spawning aggregations within one embayment has significant implications for management and monitoring programmes.

  1. Evaluating community fishery management in the Tonle Sap Lake of Cambodia

    Science.gov (United States)

    KC, K. B.; Elliott, V.; Fraser, E. D. G.; Hannah, L.; Bond, N.; Seng, R.; Farrell, T.

    2016-12-01

    The Cambodian government has reformed its fresh water fishery policy in 2012 on the Tonle Sap Great Lake. Before 2012, fishing was directly managed by the central government through fishing lot system. After 2012, lot system was abolished and a system of community fisheries (CF) was started. After the reform of fishery policy, the environment of the lake, fish resources as well as livelihoods of people dependent on the lake might have changed. In this context, using the recently conducted household survey of 800 respondents across the lake, this study assesses the impact of the reform, the differences in the involvement of inhabitants before and after the reform, and the benefits that fishers are obtaining compared to prior to reform as well as any differences in associated costs for the fishers before and after reform. The approach is to compare the differences for indicators such as lake water, lake environment including flooded forest, conservation zone, whether the inhabitants are obtaining additional socioeconomic benefits such as including more fish catch, less fishing related costs and time, more employment/engagements in fishery related activities, or social engagements. What are the limitations or whether fishers are not obtaining better than they used to get prior to fishery reform? By doing so, this study helps to quantify the environmental and economic trade-offs associated with before and after the fishery reform. This will help for the policy decision makers to plan a better fishery management system for the Tonle Sap Lake, thereby minimizing the environmental and economic impact of fishery resources management.

    2006-11-01

    This work was carried out in the Enseada da Baleia and Vila Rápida communities. Data was provided by the Co-Management Committee of the Cardoso Island State Park (PEIC) on manjuba fishery management, technique and strategies used by the fishermen, as well as locally accumulated knowledge. Based on the results, social, ecological, and economic aspects of this type of fishing were analyzed. The importance of the accumulated knowledge and experience of this community, as well as the limitations imposed by local fishing gear, was concluded to be essential in conserving manjuba fishery conditions in the area. Industrial fishing, relevant state legislation, and market conditions were found to be the main obstacles to local fishery. Various proposals are suggested for manjuba fishery management, with emphasis on the need for fishing community participation in whatever measures are ultimately implemented.

  5. Characterizing fishing effort and spatial extent of coastal fisheries.

    Directory of Open Access Journals (Sweden)

    Kelly R Stewart

    Full Text Available Biodiverse coastal zones are often areas of intense fishing pressure due to the high relative density of fishing capacity in these nearshore regions. Although overcapacity is one of the central challenges to fisheries sustainability in coastal zones, accurate estimates of fishing pressure in coastal zones are limited, hampering the assessment of the direct and collateral impacts (e.g., habitat degradation, bycatch of fishing. We compiled a comprehensive database of fishing effort metrics and the corresponding spatial limits of fisheries and used a spatial analysis program (FEET to map fishing effort density (measured as boat-meters per km² in the coastal zones of six ocean regions. We also considered the utility of a number of socioeconomic variables as indicators of fishing pressure at the national level; fishing density increased as a function of population size and decreased as a function of coastline length. Our mapping exercise points to intra and interregional 'hotspots' of coastal fishing pressure. The significant and intuitive relationships we found between fishing density and population size and coastline length may help with coarse regional characterizations of fishing pressure. However, spatially-delimited fishing effort data are needed to accurately map fishing hotspots, i.e., areas of intense fishing activity. We suggest that estimates of fishing effort, not just target catch or yield, serve as a necessary measure of fishing activity, which is a key link to evaluating sustainability and environmental impacts of coastal fisheries.

  7. The Mediterranean and Black Sea fisheries at risk from overexploitation.

    Directory of Open Access Journals (Sweden)

    Athanassios C Tsikliras

    Full Text Available The status of the Mediterranean and Black Sea fisheries was evaluated for the period 1970-2010 on a subarea basis, using various indicators including the temporal variability of total landings, the number of recorded stocks, the mean trophic level of the catch, the fishing-in-balance index and the catch-based method of stock classification. All indicators confirmed that the fisheries resources of the Mediterranean and Black Sea are at risk from overexploitation. The pattern of exploitation and the state of stocks differed among the western (W, central (C and eastern (E Mediterranean subareas and the Black Sea (BS, with the E Mediterranean and BS fisheries being in a worst shape. Indeed, in the E Mediterranean and the BS, total landings, mean trophic level of the catch and fishing-in-balance index were declining, the cumulative percentage of overexploited and collapsed stocks was higher, and the percentage of developing stocks was lower, compared to the W and C Mediterranean. Our results confirm the need for detailed and extensive stock assessments across species that will eventually lead to stocks recovering through conservation and management measures.

  20. Image of the seismogenic coupling zone in Central Chile: The amphibious experiment SPOC (Subduction Processes Off Chile)

    Nearly all interplate megathrust earthquakes occur in the seismogenic coupling zone between converging plates. In the area of the 1960 Chile earthquake (Mw = 9.5), we aim at a quantitative understanding of the seismicity and its relation to processes operating at depth and at the surface. As a first step, the offshore experiment SPOC with RV SONNE was combined with an onshore-offshore, active-passive seismic experiment between 36° and 39° S, crossing the rupture area of the 1960 Chile earthquake. The campaign comprised: (1) a 2-D wide-angle component recording chemical shots and airgun pulses along three consecutive E-W onshore profiles; (2) a seismic reflection experiment in the onshore-offshore transition; and (3) a 3-D component which recorded both active and passive sources. Offshore, the upper plate is split into many segments with pronounced forearc basins and narrow accretionary wedges. A thick subduction channel seems to cause a non-accretionary subduction mode. Covering onshore the westernmost part of a long E-W refraction seismic line (one amongst three), the profile spread of the reflection seismic survey at 38° 15`S was 54 km long, with three set-ups of 18 km length each, and extended from the coast to the east. Furthermore, the offshore-onshore transition zone is imaged by a wide-angle section resulting from the registration of the airgun shots of the marine profile with the first 18 km of the spread of the NVR survey. Different mainly eastward dipping reflection bands are observed between 5-25 km depth. These bands are interpreted to describe the internal structure of the Palaeozoic accretionary wedge in the region. The reflections between 25-45 km depth correlate with Wadati-Benioff seismicity and are suggested to image the top of the downgoing plate. Below the coast, the plate dips with c. 15° below the continent. In the central part of the profile, a break in reflectivity located below the axis of the coastal cordillera more or less coincides

  1. A Pilot Near-vertical Seismic Reflection Experiment In Central Chile Landward of The Offshore Spoc Survey

    Science.gov (United States)

    Krawczyk, C. M.; Onshore Nvr Party, Spoc

    Between 36 and 39 S, the multi-disciplinary offshore project SPOC (Subduction Processes Off Chile) was extended landwards in November 2001 by different active and passive seismic experiments, with the zone of seismic coupling, generally located between 20-40 km depth, as the prime target. Here, we report the first results from the near-vertical incidence reflection (NVR) seismic experiment component that was designed to image that part of the subduction zone between the S-America and over- riding Nazca-Plate that is located in the offshore-onshore transition zone. The NVR profile was located at 37 15`S. Covering the westernmost part of a long E-W refrac- tion seismic line (one amongst three), the profile spread was 54 km long, with three sections of 18 km length each, and extended from the coast in the west to the east. 180 geophone-groups were deployed with 100 m spacing which recorded the offshore pro- file shot by the R/V SONNE with the airgun array. Furthermore, 2 small shots in the Pacific Ocean (50 kg and 25 kg charge), 11 small shots (75 kg charge) at 7 different lo- cations within the onshore reflection seismic line, and 1 shot (150 kg charge) ca. 22.5 km east of the active spread were shot. This active NVR-experiment thereby resulted in a 45 km long 2-fold CDP line, and single-fold coverage along 72 km profile length. The preliminary data processing of single shots gives an image of different reflection bands in the upper and middle crust. On the entire profile, a 1 s TWT thick strong reflection band is observed between 3 and 4 s TWT, which shows almost no dip. On the western half of the profile, prominent reflections dip eastward from ca. 6 s TWT down to ca. 8 s TWT. Finally, in the central part of the seismic reflection profile, some relatively weaker reflections are found between 10 to 14 s TWT. All theses eastward dipping reflection bands between 6 and 14 s TWT could be interpreted as indications for the downgoing plate.

  19. Central planning, market and subsistence from a tundra perspective: Field experience with reindeer herders in the Kola Peninsula

    Directory of Open Access Journals (Sweden)

    Dessislav Sabev

    2002-04-01

    Full Text Available This paper is based on field experience in the tundra camp of a reindeer-herding brigade with mixed ethnic background (Komi, Sami, Nenets, Russians belonging to the ex-Sovkhoz of Krasnoschelie. Its purpose is to situate the new critical issues facing the reindeer-herding collectives after the economic collapse in Russia in 1998. My main argument is that the increasing economic isolation of the tundra periphery forces the herders to redefine their relationship with both the centre(s and the other tundra actors. Reindeer herding on the Kola Peninsula is analysed in relation to its heterogeneous economic system defined by the old Sovkhoz-like management and the new Western buyer of reindeer meat. Furthermore, the social environment in the herding territories has changed since the deterioration of the central planning economy, implying new renewable resources' users. After massive loss of jobs, militaries, miners and geologists came into the tundra for substantial hunting and fishing and so became actors in the local informal economy. Finally, tundra-located herders and hunters seem to be somewhere unified by a discourse against the town-based administrative power and economic actors such as mining industry. Therefore herders have to deal with both an old administrative system in the agrocentre and new realities in the tundra. Based on a case study of herding/hunting activities in a tundra camp, the paper analyses the social relationships between the different actors in the post-Soviet Kola tundra and express their quest for solutions.

  20. Microanalysis of the aerosol collected over south-central New Mexico during the alive field experiment, May-December 1989

    Science.gov (United States)

    Sheridan, Patrick J.; Schnell, Russel C.; Kahl, Jonathan D.; Boatman, Joe F.; Garvey, Dennis M.

    Thirty-eight size-segregated aerosol samples were collected in the lower troposphere over the high desert of south-central New Mexico, using cascade impactors mounted onboard two research aircraft. Four of these samples were collected in early May, sixteen in mid-July, and the remaining ones in December 1989, during three segments of the ALIVE field initiative. Analytical electron microscope analyses of aerosol deposits and individual particles from these samples were performed to physically and chemically characterize the major particulate species present in the aerosol. Air-mass trajectories arriving at the sampling area in the May program were quite different from those calculated for the July period. In general, the May trajectories showed strong westerly winds, while the July winds were weaker and southerly, consistently passing over or very near the border cities of El Paso, Texas, and Ciudad Juarez, Mexico. Aerosol samples collected during the May period were predominantly fine (0.1-0.5 μm dia.), liquid H 2SO 4 droplets. Samples from the July experiment were comprised mostly of fine, solid (NH 4) 2SO 4 or mostly neutralized sulfate particles. In both sampling periods, numerous other particle classes were observed, including many types with probable terrestrial or anthropogenic sources. The numbers of these particles, however, were small when compared with the sulfates. Composite particle types, including sulfate/crustal and sulfate/carbonaceous, were also found to be present. The major differences in aerosol composition between the May and July samples (i.e. the extensive neutralization of sulfates in the July samples) can be explained by considering the different aerosol transport pathways and the proximity of the July aerosol to the El Paso/Juarez urban plume. Winds during the December experiment were quite variable, and may have contributed to the widely varying aerosol compositions observed in these samples. When the aircraft sampled the El Paso

  4. Fishery induces sperm depletion and reduction in male reproductive potential for crab species under male-biased harvest strategy.

    Directory of Open Access Journals (Sweden)

    Luis Miguel Pardo

    Full Text Available Sperm depletion in males can occur when polygynous species are intensively exploited under a male-biased management strategy. In fisheries involving crabs species, the effects of this type of management on the reproductive potential is far from being understood. This study tests whether male-biased management of the principal Chilean crab fishery is able to affect the potential capacity of Metacarcinus edwardsii males to transfer sperm to females. Five localities in southern Chile, recording contrasting crab fishery landing, were selected to assess the potential of sperm depletion triggered by fishery. Seasonally, male crabs from each locality were obtained. Dry weight and histological condition of vasa deferentia and the Vaso-Somatic Index (VSI were determined in order to use them as proxies for sperm depletion and male reproductive condition. A manipulative experiment was performed in the laboratory to estimate vasa deferentia weight and VSI from just-mated males in order to obtain a reference point for the potential effects of the fishery on sperm reserves. Sperm storage capacity is significantly affected by fisheries; during the mating season vasa deferentia from localities with low fishery intensity were heavier than those from high intensity fisheries, and these differences were even more evident in large males. Histological section showed that this disparity in vasa deferentia weight was explained principally by differences in the quantity of spermatophores rather than other seminal material. VSI was always higher in males from localities with low fishery intensity. Males from localities with high fishery intensity showed little capacity to recover sperm reserves and the VSI of these males remained below the values of the just-mated males. Detriment in the capacity of males to transfer sperm is the first step to sperm limitation in an exploited population, thus detection of sperm depletion can be an alert to introduce changes in the

  10. An Empty Donut Hole: the Great Collapse of a North American Fishery

    Directory of Open Access Journals (Sweden)

    Full Text Available Walleye pollock (Theragra chalcogramma is North America's most abundant and lucrative natural fishery, and is the world's largest fishery for human food. The little-known demise of the "Donut Hole" stock of pollock in the Aleutian Basin of the central Bering Sea during the 1980s is the most spectacular fishery collapse in North American history, dwarfing the famous crashes of the northern cod and Pacific sardine (Sardinops sagax. This collapse has received scant recognition and became evident only in 1993 when fishing was banned by an international moratorium; nearly 20 years later it has not recovered. The history of fishing in the North Pacific Ocean after World War II offers some insights into how the Donut Hole pollock fishery developed, and the societal and economic pressures behind it that so influenced the stock's fate. Overfishing was, without a doubt, the greatest contributor to the collapse of the Aleutian Basin pollock fishery, but a lack of knowledge about population biocomplexity added to the confusion of how to best manage the harvest. Unfortunately, the big scientific questions regarding the relationship of Donut Hole fish to other stocks are still unanswered.

    Pre- and post-migration contexts of refugee children from Central America and Southeast Asia were compared. The results suggest that the culture of origin radically modulates the relationship between the pre-migration experience and the developing post-migration universe. In the case of the Central American children, the state-sponsored violence suffered in the country of origin is strongly associated with subsequent family conflicts, whereas in the case of the Southeast Asians, conflict is associated with an active social network in the community of origin, suggesting that there is a delicate balance between the support provided and the burden imposed by the extended family.

    Objective: To investigate the clinical presentation of dislodged totally implantable central venous access system (central venous port-catheter) fragments and the efficacy and safety of percutaneous retrieval of them in our hospital. Materials and methods: Ninety-two cancer patients, mean age of 53.8 years old with 51.1% male, were enrolled from January 2005 to March 2007. They were referred to our catheterization laboratory for retrieval of fractured central venous port-catheter in our hospital. All patients were followed in the outpatient department for at least 1 month after surgical insertion. The characteristics of disrupted central venous port-catheter were recorded. The procedure-related clinical condition was evaluated. Results: The most common presentation of central venous port-catheter dislodgement is irrigation resistance to infusion (51/92). The most common location of fractured fragments is between superior vena cava and right atrium (i.e. proximal end remained in superior vena cava and distal end in right atrium) (22/92). The most common fracture site of the catheter is at the anastomosis between injection port and catheter (77/92). The retrieval set used mostly is loop snare. The success rate of the percutaneous retrieval of dislodged fragment was 97.8% and the complication rate was 3.3% only. Conclusion: The faulty connection between catheter and injection port contributes mainly to dislodgement of central venous port-catheter. Percutaneous retrieval of dislodged catheter is a highly successful, safe and efficient method.

  15. Harvest control rules in modern fisheries management

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available Abstract Harvest control rules have become an important tool in modern fisheries management, and are increasingly adopted to provide continuity in management practices, to deal with uncertainty and ecosystem considerations, and to relieve management decisions from short-term political pressure. We provide the conceptual and institutional background for harvest control rules, a discussion of the structure of fisheries management, and brief introductions to harvest control rules in a selection of present day cases. The cases demonstrate that harvest control rules take different forms in different settings, yet cover only a subset of the full policy space. We conclude with views on harvest control rules in future fisheries management, both in terms of ideal and realistic developments. One major challenge for future fisheries management is closing the gap between ideas and practice.

    Tropical peatland in Southeast Asia is a vast reservoir of terrestrial carbon, which covers 24.8 million hectares and stores 68.5 PgC peat, equal to 11-14% of global peat carbon. In recent decades, large scale peatland fire has occurred frequently in that region, in which many areas of peatland were reclaimed with intention to use the land for forest plantation and rice paddy. We conducted a plot-scale peat burning experiment to elucidate the characteristics of gaseous carbon emission from a tropical peatland fire at the ground level. The experimental site was established at an open area 20 km southeast from Palangka Raya, Central Kalimantan Province, Indonesia. The size of the burning plot is 4 m in length and 3 m in width. Gas samples were collected at heights of 1.0, 0.5, 0.0 (aboveground), -0.1 and -0.2 m (belowground) through stainless steel and/or aluminum tubes settled across the edge of the plot. The concentrations of carbon dioxide (CO2), carbon monoxide (CO), methane (CH4) and particulate matter (PM) was determined. Soil temperature was recorded every 10 minutes 0.1 and 0.2 m below the ground surface. Twelve iron rods were installed in 1-m by 1-m square grid to determine the depth of burn scar. After ignition, flaming stage of peat burning was ceased within 1-2 hours. The following smoldering stage continued for a week. In the flaming stage, soil temperature at -0.1 m increased tentatively. After the smoldering stage began, the temperature rapidly increased to 350-450°C. Response of soil temperature at -0.2 m was less prominent. Concentrations of gaseous components became maximal in the flaming stage. During the smoldering stage, the concentrations gradually decreased. The influence of burning on CO2 and PM was prominently remained at -0.1 m, whereas those at -0.2 m were not so much. The averaged burnt depth was 5.8±5.1 cm. Based on bulk density of 0.22 g/cm3 and carbon content of 55.5%, the amount of carbon lost from the plot was 85.3 kg. Most of the

    Small-holder farmers in Ethiopia are facing several climate related hazards, in particular highly variable rainfall with severe droughts which can have devastating effects on their livelihoods. Projected changes in climate are expected to aggravate the existing challenges. This study examines farmer perceptions on current climate variability and long-term changes, current adaptive strategies, and potential barriers for successful further adaptation in two case study regions—the Central Rift Valley (CRV) and Kobo Valley. The study was based on a household questionnaire, interviews with key stakeholders, and focus group discussions. The result revealed that about 99 % of the respondents at the CRV and 96 % at the Kobo Valley perceived an increase in temperature and 94 % at CRV and 91 % at the Kobo Valley perceived a decrease in rainfall over the last 20-30 years. Inter-annual and intraseasonal rainfall variability also has increased according to the farmers. The observed climate data (1977-2009) also showed an increasing trend in temperature and high inter-annual and intra-seasonal rainfall variability. In contrast to farmers’ perceptions of a decrease in rainfall totals, observed rainfall data showed no statistically significant decline. The interaction among various bio-physical and socio-economic factors, changes in rainfall intensity and reduced water available to crops due to increased hot spells, may have influenced the perception of farmers with respect to rainfall trends. In recent decades, farmers in both the CRV and Kobo have changed farming practices to adapt to perceived climate change and variability, for example, through crop and variety choice, adjustment of cropping calendar, and in situ moisture conservation. These relatively low-cost changes in farm practices were within the limited adaptation capacity of farmers, which may be insufficient to deal with the impacts of future climate change. Anticipated climate change is expected to impose new

    Illegal behaviour and public enforcement of law are important theoretical and empirical subjects for Economics. They were dormant in economic scholarship, until the article of Becker, 1968, “Crime and Punishment: An Economic Approach”. In the context of Fisheries Economics, the problem can be seen as an externality arising when exclusive property rights are absent. That absence depends on the costs of defining and enforcing exclusivity and the problem becomes more complex when fisheries are t...

    Recent reports suggest that many well-assessed fisheries in developed countries are moving toward sustainability. We examined whether the same conclusion holds for fisheries lacking formal assessment, which comprise >80% of global catch. We developed a method using species' life-history, catch, and fishery development data to estimate the status of thousands of unassessed fisheries worldwide. We found that small unassessed fisheries are in substantially worse condition than assessed fisheries, but that large unassessed fisheries may be performing nearly as well as their assessed counterparts. Both small and large stocks, however, continue to decline; 64% of unassessed stocks could provide increased sustainable harvest if rebuilt. Our results suggest that global fishery recovery would simultaneously create increases in abundance (56%) and fishery yields (8 to 40%).

    Full Text Available In 1996, a census was taken of the Sicilian fisheries that engage in dolphinfish (Coryphaena hippurus L. 1758 fishing. Two different surveys were conducted; data on fishing boats were obtained from the Naval Registers and frominterviewing boat owners on the wharf. The area sampled was divided into 3 zones and 6 strata. 205 boats were recorded in the eastern zone (Tyrrhenian and Ionian seas, 57 boats located in 4 different strata were recorded in the western zone. Fishing activities in the Ionian area begin in early August and end in December. In all other areas of Sicily, dolphinfish fishing begins in early September and continues until December. A census was also taken of the equipment used by the various boats for this activity in the different areas. The surveys showed that FADs are the most commonly employed method for dolphinfish fishing. The geographical distribution, number and characteristics were recorded for each area surveyed. The catches for the 1996 fishing season distributed for strata and zone are reported.

    Central nervous system tumours comprise a heterogeneous group of neoplasms with great histological diversity. Despite the rising prevalence of these tumours in developing countries, some places like Mexico and Latin America have no representative studies that show the real impact of these tumours in our population. To describe the characteristics of the primary and secondary tumours of the central nervous system in the last 20 years in a Mexican institution. Patients with histopathological diagnosis from 1993 to 2013 in our institution, grouping them according to WHO classification 2007, characterising them by age group, gender, and anatomical location. There were a total of 511 tumours of the central nervous system. Of those, 292 were women and 219 men, with a ratio 1.3: 1, and a mean age of 49.3 years. Tumours with higher prevalence were: Meningeal tumours, 171 (33%), followed by neuroepithelial, 121 (24%). Astrocytoma had the highest prevalence in paediatric patients, whereas in those older than 20 years it was the meningioma. The supratentorial location was the most involved. This is the first study of a series of cases in Mexico that is performed by taking into account benign and malignant tumours of the central nervous system, with patients of all age groups with a range of 20 years. While this work only represents a retrospective analysis of an institution, it can be a strong indication of the epidemiology of these tumours in our environment. Copyright © 2016.

  17. FISHERY MANAGEMENT IN THE DANUBE CATCHMENT AREA

    Directory of Open Access Journals (Sweden)

    Tomislav Treer

    1999-12-01

    Full Text Available There are three successive regions of the Danube, each of which has to deal with its own problems in fisheries. Sport fishing and ecological recontruction problem matters predominate in the upper flow. These problems also characterize the middle flow, where to a certain extent, commercial fishery is coming into view, while the lower flow has to deal with commercial fishery problems to full extent. The difference is not so much due to the morphometry as to the development and state of the economy of the countries in the river basin, their legislation on fishery and the manner in which the legislation is applied. Numerous dams of the upper flow of the Danube (29 in Germany, 9 in Austria, influence significantly the ichthyocenoses. An extreme example of that is Gabčikovo dam at the Slovak-Hungarian border where fish catch decreased to one fourth. In the lower segment of the Danube fish catch falls down to one third and is followed, by a drastically negative change of fish species composition. The records show that highly valued species as sturgeons, pike and tench are in drastic decline over the last few years. The changes were caused by physical barriers, like dams and weirs, by water pollution, by increasing concentration of nutrients and heavy metals, by poaching and by overexploitation. For all those alarming reasons, some legal interventions in commercial fishery must be undertaken. In the middle flow, where the Danube flows through Croatian territory, there have also been declining trends of bentivore and phytophyl species respectively. The law supports the coexistence of sport and commercial fishery in this area and although sport fishing should be given the advantage, commercial fishing should be rigorously supervised and allowed only when there is a naturally produced surplus. Because of fish migrations and political frontiers of Danube area, it is essential that the neighboring countries coordinate their efforts in managing fisheries

    Ecosystem-based approaches to fisheries management (EAFMs) have emerged as requisite for sustainable use of fisheries resources. At the same time, however, there is a growing recognition of the degree of variation among individuals within a population, as well as the ecological consequences of this variation. Managing resources at an ecosystem level calls on practitioners to consider evolutionary processes, and ample evidence from the realm of fisheries science indicates that anthropogenic disturbance can drive changes in predominant character traits (e.g. size at maturity). Eco-evolutionary theory suggests that human-induced trait change and the modification of selective regimens might contribute to ecosystem dynamics at a similar magnitude to species extirpation, extinction and ecological dysfunction. Given the dynamic interaction between fisheries and target species via harvest and subsequent ecosystem consequences, we argue that individual diversity in genetic, physiological and behavioural traits are important considerations under EAFMs. Here, we examine the role of individual variation in a number of contexts relevant to fisheries management, including the potential ecological effects of rapid trait change. Using select examples, we highlight the extent of phenotypic diversity of individuals, as well as the ecological constraints on such diversity. We conclude that individual phenotypic diversity is a complex phenomenon that needs to be considered in EAFMs, with the ultimate realization that maintaining or increasing individual trait diversity may afford not only species, but also entire ecosystems, with enhanced resilience to environmental perturbations. Put simply, individuals are the foundation from which population- and ecosystem-level traits emerge and are therefore of central importance for the ecosystem-based approaches to fisheries management.

  20. Involving stakeholders in building integrated fisheries models using Bayesian methods.

    Science.gov (United States)

    Haapasaari, Päivi; Mäntyniemi, Samu; Kuikka, Sakari

    2013-06-01

    A participatory Bayesian approach was used to investigate how the views of stakeholders could be utilized to develop models to help understand the Central Baltic herring fishery. In task one, we applied the Bayesian belief network methodology to elicit the causal assumptions of six stakeholders on factors that influence natural mortality, growth, and egg survival of the herring stock in probabilistic terms. We also integrated the expressed views into a meta-model using the Bayesian model averaging (BMA) method. In task two, we used influence diagrams to study qualitatively how the stakeholders frame the management problem of the herring fishery and elucidate what kind of causalities the different views involve. The paper combines these two tasks to assess the suitability of the methodological choices to participatory modeling in terms of both a modeling tool and participation mode. The paper also assesses the potential of the study to contribute to the development of participatory modeling practices. It is concluded that the subjective perspective to knowledge, that is fundamental in Bayesian theory, suits participatory modeling better than a positivist paradigm that seeks the objective truth. The methodology provides a flexible tool that can be adapted to different kinds of needs and challenges of participatory modeling. The ability of the approach to deal with small data sets makes it cost-effective in participatory contexts. However, the BMA methodology used in modeling the biological uncertainties is so complex that it needs further development before it can be introduced to wider use in participatory contexts.

    is that their fishing power has not varied much over time. IFP is calculated for some of the Danish cod fisheries in the Baltic Sea. IFP appeared to be independent of the vessel composition of the reference sub- fleet and for the fleets fishing in the Eastern Baltic Sea. but less so for the Western Baltic Sea fleets....... Variations in IFP are analysed by a GLM (General Linear Model). Results suggest that fishing power has developed in the Eastern Baltic Sea cod fishery at an annual rate of 2% and 6% for trawlers and gillnetters respectively. Mechanisms of fishing power creeping may include increased technical efficiency......Using nominal fishing effort to control fishing mortality and using cpue data from commercial fisheries as abundance indices require ability to correct fishing power for temporal development. It is often assumed in ICES stock assessments that fishing power Is constant over time. However, experience...

  4. Romania's experience in using woody residues as a combustible for central heating; L'experience roumaine de l'utilisation des residus ligneux comme combustible pour le chauffage central

    Energy Technology Data Exchange (ETDEWEB)

    Lavrov, G. [Inst. des Etudes et des Projets Energetiques (Romania)

    2004-06-01

    Romania's national policy for renewable resources promotes the use of clean and renewable energy. The national policy is intended to increase the national contribution of renewable energy sources and to develop non-conventional technologies for exploiting renewable resources. This paper described two examples where woody residues are used as a combustible for central heating. The first example describes a local industry in Campeni, a village of 10,000 people located near the Aires River, which produces 54,000 tons of ligneous waste each year. A central heating plant was modernized to accept this waste as a fuel. Two old boilers were replaced with two modern, Romanian-made boilers that produce a calorific output of 8,790 kJ/kg. The efficiency of the new boilers is 83 per cent. The benefits of this modernization have been a significant reduction in pollution of the Aires River by reducing the number of ligneous waste dumped into the river. Carbon dioxide and SOx emissions have also been reduced by replacing fossil fuel with biomass. The thermal comfort of the buildings served by the heating plant has also improved because the new boilers produce 88 per cent more heat. The second example focuses on the village of Tasca in Moldavia, a forest rich region of Romania where the wood dust from local saw mills has polluted the Bicaz and Damuc Rivers. A project was launched to develop an urban district heating system by installing a new 2.5 MW boiler fueled by sawdust and ligneous waste. Consumers were connected to the thermal energy distribution system. A separate system was created to collect waste from the sawmills. The benefits of this project have been a significant reduction in the pollution of the rivers, increased comfort levels in houses and a significant reduction in air pollution because the old individual and inefficient heating systems were replaced with an efficient central heating system. 1 tab.

    Limited information is available on artisanal and subsistence shark fisheries across the Pacific. The aim of this study was to investigate Fiji’s inshore fisheries which catch sharks. In January and February 2013, 253 semi-directive interviews were conducted in 117 villages and at local harbours on Viti Levu, Vanua Levu, Taveuni, Ovalau and a number of islands of the Mamanuca and Yasawa archipelagos. Of the 253 interviewees, 81.4% reported to presently catch sharks, and 17.4% declared that they did not presently catch any sharks. Of the 206 fishers that reported to catch sharks, 18.4% targeted sharks and 81.6% caught sharks as bycatch. When targeted, primary use of sharks was for consumption or for sale. Sharks caught as bycatch were frequently released (69.6%), consumed (64.9%) or shared amongst the community (26.8%). Fishers’ identification based on an identification poster and DNA barcoding revealed that at least 12 species of elasmobranchs, 11 shark and one ray species (Rhynchobatus australiae) were caught. This study, which is the first focused exploration of the shark catch in Fiji’s inshore fisheries, suggests that the country’s artisanal shark fisheries are small but have the potential to develop into larger and possibly more targeted fisheries.

    2017-09-10

    Understanding overfishing and regulating fishing quotas is a major global challenge for the 21st Century both in terms of providing food for humankind and to preserve the oceans' ecosystems. However, fishing is a complex economic activity, affected not just by overfishing but also by such factors as pollution, technology, financial factors and more. For this reason, it is often difficult to state with complete certainty that overfishing is the cause of the decline of a fishery. In this study, we developed a simple dynamic model specifically designed to isolate and to study the role of depletion on production. The model is based on the well-known Lotka-Volterra model, or Prey-Predator mechanism, assuming that the fish stock and the fishing industry are coupled variables that dynamically affect each other. In the model, the fishing industry acts as the "predator" and the fish stock as the "prey". If the model can fit historical data, in particular relative to the productive decline of specific fisheries, then we have a strong indication that the decline of the fish stock is driving the decline of the fishery production. The model doesn't pretend to be a general description of the fishing industry in all its varied forms; however, the data reported here show that the model can describe several historical cases of fisheries whose production decreased and collapsed, indicating that the overexploitation of the fish stocks is an important factor in the decline of fisheries.

    Local adaptations to environmental conditions are of high ecological importance as they determine distribution ranges and likely affect species responses to climate change. Increased environmental stress (warming, extreme drought) due to climate change in combination with decreased genetic mixing due to isolation may lead to stronger local adaptations of geographically marginal than central populations. We experimentally observed local adaptations of three marginal and four central populations of Fagus sylvaticaL., the dominant native forest tree, to frost over winter and in spring (late frost). We determined frost hardiness of buds and roots by the relative electrolyte leakage in two common garden experiments. The experiment at the cold site included a continuous warming treatment; the experiment at the warm site included a preceding summer drought manipulation. In both experiments, we found evidence for local adaptation to frost, with stronger signs of local adaptation in marginal populations. Winter frost killed many of the potted individuals at the cold site, with higher survival in the warming treatment and in those populations originating from colder environments. However, we found no difference in winter frost tolerance of buds among populations, implying that bud survival was not the main cue for mortality. Bud late frost tolerance in April differed between populations at the warm site, mainly because of phenological differences in bud break. Increased spring frost tolerance of plants which had experienced drought stress in the preceding summer could also be explained by shifts in phenology. Stronger local adaptations to climate in geographically marginal than central populations imply the potential for adaptation to climate at range edges. In times of climate change, however, it needs to be tested whether locally adapted populations at range margins can successfully adapt further to changing conditions.

    Some studies suggest that fishery yields can be higher with reserves than under conventional management. However, the economic performance of fisheries depends on economic profit, not fish yield. The predictions of higher yields with reserves rely on intensive fishing pressures between reserves; the exorbitant costs of harvesting low-density populations erode profits. We incorporated this effect into a bioeconomic model to evaluate the economic performance of reserve-based management. Our results indicate that reserves can still benefit fisheries, even those targeting species that are expensive to harvest. However, in contrast to studies focused on yield, only a moderate proportion of the coast in reserves (with moderate harvest pressures outside reserves) is required to maximize profit. Furthermore, reserve area and harvest intensity can be traded off with little impact on profits, allowing for management flexibility while still providing higher profit than attainable under conventional management.

    To assess the functional status and long-term outcomes of endovascular management for the treatment of central veno-occlusive disease in patients undergoing hemodialysis. Retrospective chart evaluation of 600 patients with threatened upper extremity dialysis access showed central veno-occlusive disease in 69 patients (11%; 30 women and 39 men; mean age, 63.9 years; age range, 26-92 years). A total of 92 venous segments were involved with disease. Initial endovascular procedures consisted of transvenous angioplasty (n = 88) and stent placement (n = 6); there were 134 repeat interventions (14 stents). The mean follow-up was 14.5 months (range, 1-44 months). Angiographic data were reviewed prospectively by two independent observers for the extent of veno-occlusive disease. Technical failures were defined as residual stenosis of at least 30% or lesions that were unable to be dilated or crossed. Statistical analysis, including interobserver agreement and Kaplan-Meier analysis, was performed. Technical success rates for initial and follow-up interventional procedures were 90% (81 of 92 segments) and 96% (129 of 134 interventions), respectively. Two complications required treatment with interventional procedures. There was excellent interobserver agreement (kappa = 0.84; 95% confidence interval: 0.67, 0.93) for grading the degree of venous stenoses. Primary patency rates of hemodialysis access at 1, 6, and 12 months were 81%, 46%, and 22%, respectively, which significantly (P = .001) improved to assisted patency rates of 91%, 77%, and 63% at 1, 6, and 12 months, respectively. Endovascular management including a combination of angioplasty and selective stent placement can be effectively used to treat central veno-occlusive disease and preserve functional access in patients with threatened upper extremity dialysis access.

    The status of Kuwait's fisheries landings and relative abundance for major species was reviewed using research data from Kuwait Institute for Scientific Research and landing data from the Kuwait's Central Statistical Bureau. Landing data showed significant decreases for major commercial species such as zobaidy (Pampus argenteus), suboor (Tenualosa ilisha), hamoor (Epinephelus coioides), newaiby (Otolithes ruber) and hamra (Lutjanus malabaricus) while abundance data for the shrimp Penaeus semisulcatus showed significant reduction in the recent years mainly because of overfishing. The catch-rate data showed continuous decline for major species such as zobaidy, newaiby and hamoor, which indicate that stock abundances of these species are low. The reduction in stock abundance in context with changes in habitat quality, particularly the effects of reduced discharge of the Shatt Al-Arab, is discussed.

Ward, Ryan Porter, Susan Beck, George Zandt, Lara Wagner, Estela Minaya, and Hernando Tavera The University of Arizona The University of North Carolina San Calixto Observatorio, La Paz, Bolivia IGP, Lima, Peru In order to investigate the interplay between crustal shortening, lithospheric removal, and surface uplift we have deployed 50 broadband seismometers in northwestern Bolivia and southern Peru as part of the interdisciplinary Central Andean Uplift and Geodynamics of High Topography (CAUGHT) project. The morphotectonic units of the central Andes from west to east, consist of the Western Cordillera, the active volcanic arc, the Altiplano, an internally drained basin (~4 km elevation), the Eastern Cordillera, the high peaks (~6 km elevation) of an older fold and thrust belt, the Subandean zone, the lower elevation active fold and thrust belt, and the foreland Beni basin. Between northwestern Bolivia and southern Peru, the Altiplano pinches out north of Lake Titicaca as the Andes narrow northward. The CAUGHT seismic instruments were deployed between 13° to 18° S latitudes to investigate the crust and mantle lithosphere of the central Andes in this transitional zone. In northwest Bolivia, perpendicular to the strike of the Andes, there is a total of 275 km of documented upper crustal shortening (15° to 17°S) (McQuarrie et al, 2008). Associated with the shortening is crustal thickening and possibly lithospheric removal as the thickening lithospheric root becomes unstable. An important first order study is to compare upper crustal shortening estimates with present day crustal thickness. To estimate crustal thickness, we have calculated receiver functions using an iterative deconvolution method and used common conversion point stacking along the same profile as the geologically based shortening estimates. In our preliminary results, we observed a strong P to S conversion corresponding to the Moho at approximately 60-65 km depth underneath the

  3. Changing Use Patterns, Changing Feedback Links: Implications for Reorganization of Coastal Fisheries Management in the Stockholm Archipelago, Sweden

    Directory of Open Access Journals (Sweden)

    Full Text Available Property rights are important institutions for regulating the use of valuable natural resources from coastal ecosystems. In this case study, we identify and analyze property rights and user patterns related to small-scale coastal fisheries in the Stockholm Archipelago, Sweden. User patterns and user groups have changed significantly over the last century, as commercial fishing has been increasingly replaced by recreational activities. Interviews with local resource users and owners of water properties in two different areas, Möja and Ornö parishes within the Stockholm Archipelago, revealed a very diverse pattern of property and user rights, with a large number of water and fishing rights owners. Recreational fisheries, including both sport and household fishing, seem to predominate in both areas, but ownership differs. In Möja, most waters are collectively owned, whereas in Ornö, individual ownership predominates. Very few examples of local influence on fisheries management were found in either area, although the social structure for joint management does exist in Möja. Instead, larger-scale institutions at the regional, national, or international level regulate fisheries, often not addressing local conditions and fish populations. The ongoing shift in resource use has created a heterogeneous user group, and the limitations of centralized management authorities in dealing with the diversity in the coastal ecosystem have created mismatches within the social-ecological system. Combined with a large-scale decline in coastal fish stocks, these mismatches challenge the existing local property rights arrangements as well as the more centralized regulatory management structure. A key issue for fisheries management is how to develop and stimulate appropriate distribution of management functions at different geographical scales and organizational levels. The complexity and diversity in archipelago fisheries call for multilevel arrangements and cross
