  9. THE CLASSIC WAY OF FISH PROCESSING

    Full Text Available Today's population faces great difficulties in fish marketing, although it is very valuable food. The classic supply with fresh fish has little influence on its consumption, which is not remarkable anyhow. Therefore one shulud be reminded on the classic, almost forgotten, ways of fish processing that can substantially increase fish assortment and improve its distribution. After cleaning and cutting the fish (primary procedures in its processing, comes salting, after which the salted fish can become an end-product or it can be one of many semi-products in the fish production chain. The most common methods of fish salting are dry-salting, dry-wet-salting (Greek-Dalmatian and wet-salting (pickling. The aim of fish drying is its dehydratation. Our country has the experience of traditional drying, sun-drying and natural drying of fish. Each of these has its own special qualities, depending on the fish species and the drying temperature. Smoked fish gets a very distinctive and spicy aroma and a specific colour. There are two kinds of smoking - cold and warm - based on the smoke derived from burning some special trees or, lately, from smoke preparations. Marinades are old procedures of fish processing in acetic acid and specific spices which can be prepared cold, fried or cooked. Fish-roe of some specific fish species has a special value and is considered a delicacy. The most precious black caviar is derived from the sturgeon roe and some of its related species.

    Full Text Available The study on the role of middlemen in fish marketing was carried out in Igbokoda fish market in Ondo State, Nigeria with the use of structured questionnaire and personal interview to know the various activities in the fishing community and to be able to examine the socio-economic activities and characteristics of the fish marketers, the challenges in the market, the marketing procedures, the role middlemen plays and structures encountered in the fish business using descriptive analysis, such as the use of table, frequency, counts, mean and percentage. From this study, it was discovered that majority (42% of the respondents were within the age group of 31-40 years, thus indicating that most of them are within the economically active population. Majority of the marketers were involved in co-operative societies while only 10% were not involved in any co-operative society, which on the other hand indicate high level of rural poverty in the fishing community. 35% of the respondents have only one middleman, 22% have 2 middlemen and 38% of the respondents have 3 middlemen which indicate that their profit margin reduced as the number of middlemen increased. Fish sales in bulk and unit were observed in the area. Fish marketing, challenges and benefits that can be derived from it was also considered as well as facilities as a way of strengthening fish marketing structure by improving the bargaining power of traders and increasing the profit margin.

  20. Fish market prices drive overfishing of the 'big ones'.

    Tsikliras, Athanassios C; Polymeros, Konstantinos

    2014-01-01

    The relationship between fish market price and body size has not been explored much in fisheries science. Here, the mean market prices and fish body size were collected in order to examine the hypothesis that large fish, both among- and within-species, are being selectively targeted by fisheries because they may yield greater profit. Trophic levels, vulnerability to fishing and global landings were also collected because these variables may also be related to the market fish price. These relationships were examined using generalized additive models (GAM), which showed that, among species, fish market price was positively dependent on maximum total length (P = 0.0024) and negatively on landings (P = 0.0006), whereas it was independent of trophic level (P > 0.05) and vulnerability to fishing (P > 0.05). When the fish price vs. size relationship was tested within-species, large individuals were consistently attaining higher market prices compared to their medium and small-sized counterparts. We conclude that the selective removal of the larger fish, which is driven by their market price and to a lesser extent by their availability, may contribute to their overfishing.

    Full Text Available This paper focuses on fresh fish trade networks found in the street markets of Palmas, capital of Tocantins state, Brazil, so as to identify the economic agents involved and the various geographical spaces which interact as a result of these networks. Fresh fish trade in Palmas takes place in distributor warehouses, grocery stores, supermarkets and hypermarkets, fish shops, and fishing communities, but it is street markets that constitute the most popular sale venues. Market sellers establish upstream supply networks with sectors in the fish food system (suppliers in primary and secondary production, distribution, and retail, whose interactions generate connections in Palmas (fishermen, distributors, retailers on a local scale, as well as connections with locations in Tocantins and Pará states (fishermen, fisheries, cold storage companies on a regional scale. Sellers also establish downstream trade networks with the end consumer at markets and with establishments in the food and small retail sectors, whose interactions produce mostly local connections, in Palmas and in the Luzimangues district (close to Palmas. Such connections are marked by consumption processes in these urban areas. Key-words: network, fresh fish trade, street markets.

    Traditional fish processing technologies are important in the preservation and utilization of fish in many developing countries. These technologies as well as the quality of the products arc poorly defined and understood. This study therefore investigated the production, quality characteristics and utilization of traditional cured fish products using field surveys and laboratory techniques. It was found that simple traditional technologies for smoking, salting and drying are used to process fish in Ghana; infrastructural requirements for traditional fish processing have high local material input. The cured fish products have distinct sensory, physico-chemical properties and variable storage characteristics. Processors' perceptions of important quality attributes of cured fish products were linked to storage, marketing and other product delivery characteristics. Consumers' perceptions and expectations of desirable quality attributes however were found to he dependent upon the type of cured fish product and the food in which it is used. Cost was found to be the most important factor influencing the utilization of animal protein foods; other factors were nutritional quality, beliefs and food habits. Animal protein consumers showed a high preference for fish in general and cured fish products in particular. U sing central composite rotatable design for k = 3, representing salting time (0 - 24), drying temperature (40°C - 60°C) and drying time (6 - 20 hours), equations for predicting objective and subjective quality indices were developed. The critical salting time for attaining minimum moisture content were 20.5, 12 and 8.5 hours respectively for products dried at 40°C, 50°C and 60°C. At each salting time, the mean hardness score was dependent on the drying temperature and drying time whilst the mean colour and overall acceptability scores were influenced by drying temperature. It was found that the long salting time (24-72 hours) and drying time (5

    Parasites still become the major problem in ornamental fish as the fast grown of its trading in Indonesia. Parasites causes diseases in ornamental fish hence followed by death and reducing its appearence. In this study, the prevalence of parasites in 100 apparently healthy ornamental fishes namely Guppy (Poecilia reticulate) and Goldfish (Carrasius auratus) were determined. The method of this research used was survey in local fish market in Medan from March to May 2017 The aim of this study was to determine the parasite that infects aquarium fishes and find out its prevalence. For this purpose, ornamental fishes were examined for parasites from their skin, fin, gill and intestine using wet mount method under a light microscope. The survey result showed that parasites that infect Guppy and Goldfish were Monogenea (Dactylogyrus sp and Gyrodactylus sp) in their skin and gill, Protozoa (piscinodinium sp) in their gill and Nematoda (Capillaria sp) in abdominal cavity. Prevalence rate of parasites that attack Guppy in Medan is Dactylogyrus sp (8%), Gyrodactylus sp (14 %), Piscinodinium sp (6%) and Capillaria sp (8%). Then, prevalence rate of Capilaria sp that attack Goldfish is 4%. The conclusion of this work revealed that the prevalence rate of ectoparasite and endoparasites in ornamental fishes in Medan had the low rate as well as there was no pathological findings is observed. However, these parasites could be a harmful parasitic diseases in case there is the changes in aquarium environment and improper fish handling.

    Coral reef fisheries are crucial to the livelihoods of tens of millions of people; yet, widespread habitat degradation and unsustainable fishing are causing severe depletion of stocks of reef fish. Understanding how social and economic factors, such as human population density, access to external markets, and modernization interact with fishing and habitat degradation to affect fish stocks is vital to sustainable management of coral reef fisheries. We used fish survey data, national social and economic data, and path analyses to assess whether these factors explain variation in biomass of coral reef fishes among 25 sites in Solomon Islands. We categorized fishes into 3 groups on the basis of life-history characteristics associated with vulnerability to extinction by fishing (high, medium, and low vulnerability). The biomass of fish with low vulnerability was positively related to habitat condition. The biomass of fishes with high vulnerability was negatively related to fishing conducted with efficient gear. Use of efficient gear, in turn, was strongly and positively related to both population density and market proximity. This result suggests local population pressure and external markets have additive negative effects on vulnerable reef fish. Biomass of the fish of medium vulnerability was not explained by fishing intensity or habitat condition, which suggests these species may be relatively resilient to both habitat degradation and fishing. © 2012 Society for Conservation Biology.

    Full Text Available Oman’s fish exports have shown an increasing trend while supplies to the domestic market have declined, despite increased domestic demand caused by population growth and income. This study hypothesized that declining fish supplies to domestic markets were due to inefficiency of the transport function of the fish marketing system in Oman. The hypothesis was tested by comparing the observed prices of several fish species at several markets with optimal prices. The optimal prices were estimated by the dual of a fish transport cost- minimizing linear programming model. Primary data on market prices and transportation costs and quantities transported were gathered through a survey of a sample of fish transporters. The quantity demanded at market sites was estimated using secondary data. The analysis indicated that the differences between the observed prices and the estimated optimal prices were not significantly different showing that the transport function of fish markets in Oman is efficient. This implies that the increasing trend of fish exports vis-à-vis the decreasing trend of supplies to domestic markets is rational and will continue. This may not be considered to be equitable but it is efficient and may have long-term implications for national food security and have an adverse impact on the nutritional and health status of the rural poor population. Policy makers may have to recognize the trade off between the efficiency and equity implications of the fish markets in Oman and make policy decisions accordingly in order to ensure national food security.

    The substitution of high-value fish species for those of lower value is common practice. Although numerous studies have addressed this issue, few have been conducted in Mexico. In this study, we sought to identify fresh fillets of fish, sharks, and rays using DNA barcodes. We analyzed material from "La Viga" in Mexico City, and other markets located on the Gulf and Caribbean coasts of Mexico. From 134 samples, we obtained sequences from 129, identified to 9 orders, 28 families, 38 genera, and 44 species. The most common species were Seriola dumerili, Pangasianodon hypophthalmus, Carcharhinus falciformis, Carcharhinus brevipinna, and Hypanus americanus. Pangasianodon hypophthalmus was most commonly used as a substitute for higher-value species. The substitution rate was 18% of the total. A review of the conservation status of the specimens identified against the IUNC list enabled us to establish that some species marketed in Mexico are threatened: Makaira nigricans, Lachnolaimus maximus, Hyporthodus flavolimbatus, and Isurus oxyrinchus are classified as vulnerable; Lopholatilus chamaeleonticeps and Sphyrna lewini are endangered; and the status of Hyporthodus nigritus is critical. These results will demonstrate to the Mexican authorities that DNA barcoding is a reliable tool for species identification, even when morphological identification is difficult or impossible.

  5. From Fishing to Fish Processing: Separation of Fish from Crustaceans in the Norway Lobster-Directed Multispecies Trawl Fishery Improves Seafood Quality.

    Directory of Open Access Journals (Sweden)

    Junita D Karlsen

    Full Text Available Fishing gears have negative impacts on seafood quality, especially on fish in the mixed trawl fishery targeting Norway lobster (Nephrops norvegicus. In this fishery, which is worth about €80 millions in Denmark alone, the quality of fish can be significantly improved by simple gear changes. A trawl codend divided into an upper and lower codend was designed to separate fish from Norway lobster during the fishing process by encourage fish to swim into the upper codend by using a frame at the entrance of the lower codend. Separate codends for fish and Norway lobster in the same gear provide the opportunity to selectively reduce small low-value fish, which will reduce catch weight and sorting time onboard the vessel. For this horizontally divided test codend and a standard codend, in which the catch was mixed, quality assessments were performed on the same batches of fish during three steps of the value chain: i aboard the fishing vessel; ii at the Fishermen's Collection Central, and iii in the production plant. Four species of fish and fillets from fish caught in the upper codend of the test codend were of significantly better quality for several of the assessed parameters compared with those caught in the standard codend: i newly caught fish showed significantly less scale loss and discolourations and had significantly better texture; ii landed fish had significantly better skin appearance and texture and significantly fewer discolourations; and iii fillets showed significantly fewer blood spots and had significantly better texture. There were no differences in injuries for newly caught fish or gaping and bruises for fillets between the test and standard codends. The decrease in catch-related damages in the test codend is explained by little contact between fish and animals with hard or spiny surfaces due to successful separation of fish and Norway lobster into the upper and lower codends, respectively, and by lower catch weight in the upper

    The management of small-scale freshwater fisheries in Amazon has been based usually on surveys of urban markets, while fisheries of rural villages have gone unnoticed. We compared the fishing characteristics (catch, effort and selectivity) between an urban market and five small villages in the Lower Tocantins River (Brazilian Amazon), downstream from a large reservoir. We recorded 86 and 601 fish landings in the urban market and villages, respectively, using the same methodology. The urban fishers showed higher catch per unit of effort, higher amount of ice (related to a higher fishing effort, as ice is used to store fish catches) and larger crew size per fishing trip, but village fishers had a higher estimated annual fish production. Conversely, urban and village fishers used similar fishing gear (gillnets) and the main fish species caught were the same. However, village fishers showed more diverse strategies regarding gear, habitats and fish caught. Therefore, although it underestimated the total amount of fish caught in the Lower Tocantins River region, the data from the urban market could be a reliable indicator of main fish species exploited and fishing gear used by village fishers. Monitoring and management should consider the differences and similarities between urban and rural fisheries, in Amazon and in other tropical regions.

    Full Text Available Objective: To understand the existing fish distribution and marketing systems, assess marketing costs and margins and identify constraints of fish marketing systems. Methods: Data were collected from three different markets by fishermen, commission agents, wholesalers, retailers, day laborers etc. through questionnaire interviews and participatory approach during June to September, 2013. Results: Four types of marketing channel were identified from farmers to consumers in all the three fish markets through a number of intermediaries. The daily supply of total fish in Binodpur Market, Talaimari Market and Shaheb Market was estimated 0.8-1 ton, 0.2-0.3 ton and 8-8.1 ton, respectively. Virtually, most of the fish (75% is imported from outside; the local supply amount is only 25%. The total marketing cost of wholesalers and retailers of the three markets were $ 8.58 and $ 6.47 per day, respectively. The average marketing margin of the wholesalers and retailers of the three markets were $ 0.18 and $ 0.25 per kg respectively. Income of fisherman, wholesaler, retailer and day laborer was estimated at $ 350, $ 9.75, $ 6.48, and $ 1.69, respectively. Conclusions: Traders have broadly improved their food consumption, standards of living, purchasing power, choice and ability as an economic sector.

  11. A review of lipid extraction from fish processing by-product for use as a biofuel

    2014-01-01

    Fish processing facilities generate a significant amount of fish by-products that could be an important source of energy, food, or industrial feedstock. While fish oil is a natural source of omega-3 polyunsaturated fatty acids (mostly eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA)) used in nutritional supplements, the ability to extract, refine, and get to market of these oils may be challenging at processing facilities where there is limited infrastructure and plants are remotely located. Under these conditions, extraction of oil from fish by-product for use as an in-house or regional fuel may be both economically and environmentally be a more sustainable approach. Processes to extract and refine fish oil for fuel are less energy intensive than the processes for nutritional quality oils and do not require the stringent product specifications and approval process as in the food and pharmaceutical industry. Unlike food crops, extraction of oil from fish residue does not negatively impact food production. This paper presents an overview of developments made in fish oil extraction methodologies including physical, chemical and biological processes. - Highlights: • We have reviewed various lipid extraction methods from fish residue. • Low grade fish oils for fuel applications can be beneficial to facility and region. • The environmental impacts and safety issues can be reduced using SFE method

    The relationship between fish market price and body size has not been explored much in fisheries science. Here, the mean market prices and fish body size were collected in order to examine the hypothesis that large fish, both among- and within-species, are being selectively targeted by fisheries because they may yield greater profit. Trophic levels, vulnerability to fishing and global landings were also collected because these variables may also be related to the market fish price. These relationships were examined using generalized additive models (GAM), which showed that, among species, fish market price was positively dependent on maximum total length (P = 0.0024) and negatively on landings (P = 0.0006), whereas it was independent of trophic level (P > 0.05) and vulnerability to fishing (P > 0.05). When the fish price vs. size relationship was tested within-species, large individuals were consistently attaining higher market prices compared to their medium and small-sized counterparts. We conclude that the selective removal of the larger fish, which is driven by their market price and to a lesser extent by their availability, may contribute to their overfishing. PMID:25392754

    Full Text Available Histamine fish poisoning is quite common and occur in consequence of microbial decarboxylase whose activity begin early in the post-mortem but are triggered in consequence of abuse in the shelf life of fish products. In this study forty-eight samples of tuna, mackerel, anchovies, sardines, fresh or processed were sampled from fish shops and supermarkets in the City of Bologna in the period from January to July 2010. Concentration of histamine was assessed using ELISA quantitative test and presence of psicrotrophic histamine forming bacteria was searched using a modified Niven agar medium which allow detection of suspect colonies that were confirmed by PCR for detecting the presence of the histidine decarboxylase genes in their DNA. The positive colonies were then identified on the basis of their morphology, Gram reaction and biochemical characteristics with API20E. The differential capability of the Niven agar was found to be low and approximately one fifth of the suspect colonies were confirmed by the PCR test, which however included both strong and weak histamine producing strains. The presence of Morganella morganii was associated with concentration of histamine 460 mg∙kg-1 above the allowed limit in a sample of tuna sampled from a fish shop. The same bacterium was found in samples of Atlantic horse mackerel (Trachurus trachurus. High histamine concentration (between 258 and > 300 mg∙kg-1 were observed in salted European pilchard and European anchovy (228 mg∙kg-1 sold loose in supermarkets. Because temperature abuse could occur when Tuna (fresh/defrozen are hold on chopping board to sell fresh cuts and during shelf life of salted pilchard and pickled anchovies held in opened cans in chilled display cabinets for extended period, which might results in very high histamine concentration, controls on time and temperature at the retail, in addition to those done during the harvest and processing are needed.

    2017-01-01

    Fish consumption in Mexico is considered low (around 12 kg per person per year) and non-homogeneously distributed across the country. One of the reasons for this situation is the scarcity of wholesale selling sites. In this context, the Mercado del Mar (MM), located in Guadalajara city, Jalisco, is the second biggest wholesale fish market in Mexico, with a distribution of about 500 tons per day and a variety of about 350 different species of fish. In this paper, we argue that MM has accumulated social capital, which is formed from two main resources: buyer and seller relationships, and reputation. Specifically, the MM manages a broad and intensive interaction among business actors and the already achieved reputation allows the MM to adapt to market changes. To validate our hypotheses, an empirical study was conducted in 2015 by means of interviews to fish wholesalers in the MM and a sample of their suppliers and buyers. For simplicity we have only considered fresh water fish. We have followed snow-ball sampling as the survey strategy. Results show that the MM has responded to fish market dynamics organizing a complex network of buyers and suppliers whose relationships can be explained in the form of strong and weak ties. At the same time, reputation has been the central resource to build this social capital and also gives place to market transactions. Additionally, the strategic position of Guadalajara city and the well-connected routes have facilitated fish bulking and distribution in the region. PMID:29016637

    The present study relates to the food processing machinery and, more specifically machine for producing boneless comminuted meat from raw fish fillet. This machine is of belt and drum type meat bone separator designed for small scale fish processing in a continuous mode. The basic principal involved in this machine is compression force. The electric geared motor consists of 1HP and the conveyor belt has a linear velocity of 19 to 22 m min(-1), which was sufficient to debone the fish effectively. During the meat bone separation trials an efficiency up to 75 % on dressed fish weight basis was observed and with a capacity to separate 70 kg h(-1) of meat from fish at the machine speed of 25 rpm. During the trials, it was demonstrated that there was no significant change in the proximate composition of comminuted fish meat when compared to unprocessed fish meat. This design has a greater emphasis on hygiene, provision for cleaning-in-place (CIP) and gives cost effective need and reliability for small scale industries to produce fish meat in turn used for their value added products.

    Chitin is a biodegradable biopolymer with a variety of commercial applications, including in the food food-supplement industries as a marine-derived nutraceutical. The purpose of this study was to characterize the molecular structure of chitin extracted from fish scales of important marine fish purchased from local markets in North Sulawesi. Chitin compound material was obtained from a specific fish scale, and then sequentially carrying out a boiling treatment to separate it from a complex with collagen. From the scales of two fish species, parrotfish (Chlorurus sordidus) and red snapper (Lutjanus argentimaculatus), the rendemen of chitin obtained were 45 % and 33%, respectively. Structural characteristics of the chitin were discussed by FTIR (Fourier Transform Infrared) analysis data. FTIR analysis was done using infrared spectroscopy, which is the resulting spectrum represents the molecular absorption and transmission, creating a molecular fingerprint of the sample. The molecular structure of chitin, C18H26N2O10, where the hydroxyl group on the second carbon replaced by acetyl amide, was shown by the infrared spectra. In the infrared spectra, chitin from parrot fish scales indicated the amide band at 1627.13 cm-1, and chitin from red snapper fish scales the amide band at 1648.09 cm-1 which are a typical one for marine chitin. The hydroxyl and amino bands at the ranged spectra up to 3500 cm-1. The yields of chitin isolated from fish scale were relatively huge. Some treatments are necessary to confirm the molecular conformation and deacetylation behavior. All products from the extraction of fish scales could be more accessible for structural modifications to develop biocompatible materials for pharmaceutical purposes.

    2009-01-01

    Fish is highly nutritious as it contains easily digestible proteins and nutritionally important vitamins and polyunsaturated fatty acids. However, due to high ambient temperature in tropical countries, fish is spoiled rapidly. Spoilage of fish during transportation and storage amounting to about 30% of the catch results in heavy economic losses. The microbiological hazard related to the presence of food-borne pathogens is also common in both marine and aqua-cultured fish and shellfish. In dried products (moisture content, < 20%) insects are mainly responsible for the loss of quality during storage. Radiation processing can play a major role in ensuring security and safety of fish and fishery products by reducing post-harvest losses and eliminating pathogenic microorganisms. Being a 'cold process' the technology helps in retaining the quality of fishery products in 'as is' condition. (author)

    Since regulation of water content of the dried fish is an important factor for the quality of the fish, water-losing process during drying (squid and Japanese horse mackerel) was analyzed through neutron beam imaging. The neutron image showed that around the shoulder of mackerel, there was a part where water content was liable to maintain high during drying. To analyze water-losing process more in detail, spatial image was produced. From the images, it was clearly indicated that the decrease of water content was regulated around the shoulder part. It was suggested that to prevent deterioration around the shoulder part of the dried fish is an important factor to keep quality of the dried fish in the storage.

    Full Text Available This study evaluated various aspects of the profile of pacu (Mylossoma spp., Myleus spp., Metynnis spp. fish marketed on the Cai N’água floating platform of Porto Velho (RO from 1985 to 2004. Inter- and intra-annual variations in yield, variation in fish length and general characteristics of the fishing are reported. The annual pacu yield ranged from 33,000kg to 146,000kg (average = 86,585kg, representing from 6.6% to 20.45% of the total landings in the studied period. These variations followed the hydrologic cycle, and the greatest yields were recorded in the years following the highest water levels. The monthly production ranged from 0 to 42,366kg (average = 5,772kg and it was related to reproductive migration. The pacu presented variations in standard length from 14 to 20cm (18.72cm ± 3.69, mean ± sd. The fishing was based on the use of seines and gill nets and the main environments of capture were tributaries of the low Madeira River (Jamari, Oropiara, Machado and Novo Aripuanã. The CPUE calculated for 2003 to 2005 was 15kg*fisherman 1day-1 (sd = ±21. The results show that the category constituted during this period an important resource for local commercial exploitations, as verified in other regions of the Amazon.

    2013-01-01

    Full Text Available Although there has been a considerable debate on market segmentation over five decades, attention was merely devoted to single stages of the segmentation process. In doing so, stages as segmentation base selection or segments profiling have been heavily covered in the extant literature, whereas stages as implementation of the marketing strategy or market definition were of a comparably lower interest. Capitalizing on this shortcoming, this paper strives to close the gap and provide each step of the segmentation process with equal treatment. Hence, the objective of this paper is two-fold. First, a snapshot of the segmentation process in a step-by-step fashion will be provided. Second, each step (where possible will be evaluated on chosen criteria by means of description, comparison, analysis and synthesis of 32 academic papers and 13 commercial typology systems. Ultimately, the segmentation stages will be discussed with empirical findings prevalent in the segmentation studies and last but not least suggestions calling for further investigation will be presented. This seven-step-framework may assist when segmenting in practice allowing for more confidential targeting which in turn might prepare grounds for creating of a differential advantage.

    Full Text Available The temporal trend in the mean trophic level (mTL, fisheries-in-balance index (FIB, trophic categories landing (TrC and landing profile (LP of the exploited marine community (82 species in the Argentinean-Uruguayan Common Fishing Zone (AUCFZ were examined from 1989 to 2003. The total landings (Yt (rs=-0.561; P< 0.05 and the Yt of carnivores and top predators has declined, while the Yt of herbivores, detritivores and omnivores has increased. Consequently, the mTL significantly decreased (rs =-0.88; P< 0.01 at a rate of 0.41 from 1991 (mTL =3.81 to 2003 (mTL =3.4, and the FIB index has declined in the last 6 years. The LP temporal pattern showed four periods with significant differences in their species composition and Primary Production Required, which shows a strong decline in the traditional fishery resources (i.e. Merluccius hubbsi, Micropogonias furnieri, and increases in crustacean (Chaceon notilis, molluscs (Zygochlamys patagonica and some fishes (Macrodon ancylodon, Macruronus magallanicus, Rajidae. The mTL trend reflects the changes in the AUCFZ landing structure. This was characterized by large, slow-growing and late-maturing species during the early 1990s, while during recent years, early 2000s, it was mainly characterized by medium-sized fishes, crustaceans and molluscs. The examination of the mTL, FBI, TrC trajectories and LP temporal pattern suggests that new fishery resources are developing or that the fishing effort has been redistributed from overexploited resources to lightly exploited resources. In addition, the examination of discriminator and common species, and the fact that traditional resources are being over-fished support the hypothesis that the mTL trend has been influenced more by the impacts of new fishing technologies than the changes in market-driven exploitation and environmental fluctuation. These results provide evidence of the fishing down process along AUCFZ.

  18. The licensing processes influence on nuclear market

    Locatelli, Giorgio; Mancini, Mauro; Sainati, Tristano; Sallinen, Liisa

    2011-01-01

    The paper deals with the licensing nuclear power plants; it focuses primarily on the licensing process implications into the international nuclear market. Nowadays there are twenty-six countries that are planning to build new nuclear facilities, and thirty-seven where nuclear reactors are proposed; on the other hand, there are mainly ten international reactor vendors. At international level, there are few vendors that have sufficient resources, capabilities and experience to carry out the design and delivering of a nuclear power plant in the international market; On the other hand, the licensing processes are strictly dependent on national law frameworks, and on the nuclear policies. The paper proposes a comparison of six licensing processes (the ones established in Finland, France, Italy, South Korea, USA and UK), and analyzes its main features and implications; the IAEA licensing process is taken as reference point. The objective of the paper is to propose a systemic approach for considering the licensing procedures. The framework proposed enables facilitating the licensing management and inferring the main features of licensing contexts. The paper concludes with a forecast of the nuclear licensing context, especially with respect to the fourth generation of nuclear reactors. (author)

    Background: As the improvement of the living standard, the safety of food becomes more and more concerned currently. The fish is healthy food with more protein but less fat. Purpose: We bought ten species of fish from the market, which are often eaten by Chinese, and analyzed the trace elements of them by instrumental neutron activation analysis (INAA). So some detecting methods should be applied to give some suggestions for human. Methods: First of all, we choose six species of fresh water fish, including grass carp, weever, Wuchang Fish, tilapia, crucian, carp, and four species of frozen sea fish, including hairtail, yellow croaker, salmon, ling. All of them were collected from a supermarket in Beijing. Secondly, we remove the squama by Teflon coated scissor, wash the fish with de-ionized water and use ashless filter paper to absorb the water on the fish. Then we cut the squama-less part with titanium knife for about 10 g, put them into plastic bags separately and sealed, balance the net weight, use a tablet machine to press them into slice and freeze at -18℃ for 12 h. And then we put them into a vacuum desiccator to pump for 72 h, balance dry fish, calculate the ratio of moisture and triturate the sample into about 40 meshes in agate. Finally, we prepare three sub-samples about 300 mg with each packed by plastic bag for analysis. We put the samples, NIST-1632a and chemical standard material together, irradiate in micro neutron source reactor (MNSR) for 16 h, measure the radioactivity by Ge detector after cooling 5 d or 10 d, and calculate the contents of 16 elements by the ko-NAA and the relative method. Results: The contents of trace elements are different between fresh water fish and sea fish. The contents of As, Hg, Br: Na, Se in sea fish are apparently higher than fresh water fish, but the contents of Rb and Zn are contrary. Considering most fresh water fishes are feed, Zn was probably added in fodder. The content of As in weever is 2.4 μg·g -1 , the

Dry ashing procedure has been employed to prepare sample solutions. Result indicate that edible muscle tissue of these fish, in general, contain higher amounts of potassium, calcium, sodium and magnesium, moderate quantities of zinc and iron and lessor amounts of copper and manganese. However, cadmium and lead were found to be below the limit of detection. (author)

  2. Trend Switching Processes in Financial Markets

    Science.gov (United States)

    Preis, Tobias; Stanley, H. Eugene

    For an intriguing variety of switching processes in nature, the underlying complex system abruptly changes at a specific point from one state to another in a highly discontinuous fashion. Financial market fluctuations are characterized by many abrupt switchings creating increasing trends ("bubble formation") and decreasing trends ("bubble collapse"), on time scales ranging from macroscopic bubbles persisting for hundreds of days to microscopic bubbles persisting only for very short time scales. Our analysis is based on a German DAX Future data base containing 13,991,275 transactions recorded with a time resolution of 10- 2 s. For a parallel analysis, we use a data base of all S&P500 stocks providing 2,592,531 daily closing prices. We ask whether these ubiquitous switching processes have quantifiable features independent of the time horizon studied. We find striking scale-free behavior of the volatility after each switching occurs. We interpret our findings as being consistent with time-dependent collective behavior of financial market participants. We test the possible universality of our result by performing a parallel analysis of fluctuations in transaction volume and time intervals between trades. We show that these financial market switching processes have features similar to those present in phase transitions. We find that the well-known catastrophic bubbles that occur on large time scales - such as the most recent financial crisis - are no outliers but in fact single dramatic representatives caused by the formation of upward and downward trends on time scales varying over nine orders of magnitude from the very large down to the very small.

    The risks and benefits of fish from markets in Chinese cities have not previously been fully evaluated. In the present study, 24 common fish species with more than 400 individual samples were collected from markets from five big Chinese cities in 2007. The main nutrients and contaminants were measured and the risk-benefit was evaluated based on recommended nutrient intakes and risk level criteria set by relevant authorities. The comprehensive effects of nutrients and contaminants in marine oily fish were also evaluated using the data of two related human dietary intervention trials performed in dyslipidemic Chinese men and women in 2008 and 2010, respectively. The results showed that concentrations of contaminants analyzed including DDT, PCB{sub 7}, arsenic and cadmium were much lower than their corresponding maximum limits with the exception of the mercury concentration in common carp. Concentrations of POPs and n-3 LCPUFA, mainly EPA and DHA, were positively associated with the lipid content of the fish. With a daily intake of 80-100 g marine oily fish, the persistent organic pollutants in fish would not counteract the beneficial effects of n-3 LCPUFA in reducing cardiovascular disease (CVD) risk markers. Marine oily fish provided more effective protection against CVD than lean fish, particularly for the dyslipidemic populations. The risk-benefit assessment based on the present daily aquatic product intake in Chinese urban residents (44.9 and 62.3 g for the average values for all cities and big cities, respectively) indicated that fish, particularly marine oily fish, can be regularly consumed to achieve optimal nutritional benefits from n-3 LCPUFA, without causing significant contaminant-related health risks. However, the potential health threat from contaminants in fish should still be emphasized for the populations consuming large quantities of fish, particularly wild fish. - Highlights: Black-Right-Pointing-Pointer We collected 24 fish species with more than

    This study evaluated different cooking processes (roasted, cooked and fried) on micronutrient (Ca, Fe, K, Na, Se and Zn) and total Hg content in fish species most consumed by Manaus residents and surrounding communities. Twelve different fresh water fish species were purchased at the central receiving market (CEASA) in Manaus and prepared at the INPA Food and Nutrition Laboratory. In total 64 fish samples were analysed. Analytical determinations were performed by Neutron Activation Analysis Technique (NAA) for micronutrients and Atomic Absorption Spectrometry (CV AAS) for total Hg. All analytical methods were developed and validated for precision and accuracy by means of reference material analyses with certified values for the elements determined. The concentration variation of the analyzed elements was: Hg (2392 to 19 μ kg -1 ); K (19187 to 1185 mg kg -1 ); Ca (14590 to 994 mg kg -1 ); Na (18386 to 12850 mg kg -1 ); Fe (5580 to 4 mg kg -1 ); Se (5249 to 129 μg kg -1 ) and Zn (684 to 15 mg kg -1 ). The effect of the different cooking processes on the variation of micronutrient composition was quite significant. On the other hand Hg composition variation seems to be more related to fish species rather than the cooking process itself. As was expected, predatory species presented higher Hg and Se levels.

    Fish and shrimp are common healthy sources of protein to a large percentage of the world's population. Hence, it is vital to evaluate the content of possible contamination of these marine-foods. Six species of fishes and two species of shrimps were collected from the local markets of Mashhad, Iran. The mercury (Hg) concentration of samples was determined by atomic absorption spectrophotometry using a mercuric hydride system (MHS 10). High concentration of total Hg was found in Clupeonella cultriventris caspia (0.93 ± 0.14 μg/g) while the lowest level was detected in Penaeus indicus (0.37 ± 0.03 μg/g). Mean Hg levels in fish and shrimp samples were 0.77 ± 0.08 μg/g and 0.51 ± 0.05 μg/g, respectively. Farmed species (except for P. indicus) and all samples from Persian Gulf and the Caspian Sea had mean mercury concentrations above 0.5 μg/g, which is the maximum standard level recommended by Joint FAO/WHO/Expert Committee on Food Additives (JECFA). All samples had also mean Hg concentrations that exceeded EPA's established safety level of 0.3 μg/g. A little more extensive analysis of data showed that weekly intake of mercury for the proportion of the Iranian population consuming Hg contaminated fish and shrimp is not predicted to exceed the respective provisional tolerable weekly intakes recommended by JECFA. However, the Iranian health and environmental authorities should monitor Hg contamination of the fishes and shrimps before marketing.

    Full Text Available The most common problems in the fish processing industry relate to high water consumption and the generation of effluents with concentrated organic loads. Given that reuse can represent an alternative for sustainable development, this study sought to assess the potential for recycling effluents produced in a fish-processing plant. In order to do so, the final industrial effluent was analyzed using the American Public Health Association (APHA standard effluent-analysis method (2005. In addition, the study assessed treatments which produce effluents meeting the requirements prescribed by different countries' regulations for reuse and recycling. The results found that effluents with smaller organic loads, such as those from health barriers and monoblock washing, can be treated in order to remove nutrients and solids so that they can be subsequently reused. For effluents produced by the washing and gutting cylinders, it is recommended that large fragments of solid waste be removed beforehand. Effluents can in this way attain a quality compatible with industrial reuse. This study further highlights the possibility of treating effluents so as comply with drinking water standards. This would potentially allow them to be used within the actual fish-processing procedure; in such a case, a revision of standards and measures for controlling use should be considered to prevent microbiological damage to products and risks to handlers and final consumers.

    Full Text Available The fundamental characteristic of contemporary marketing is the total opening towards three major directions: consumer needs, organization needs and society’s needs. The continuous expansion of marketing has been accompanied by a process of differentiation and specialization. Differentiation has led to the so called “specific marketing”. In this paper, we aim to explain that in the retail companies, the concept of sales marketing can be distinguished as an independent marketing specialization. The main objectives for this paper are: the definition and delimitation of consumer goods’ sales marketing in the retail business and the sectoral approach of the marketing concept and its specific techniques for the retail activities.

    Mercury content and fatty acids in muscles of Perca fluviatilis L. (European perch), Leuciscus idus L. (ide), Cyprinus carpio L. (European or common carp), Oncorhynchus mykiss Walb. (rainbow trout), Platichthys flesus L. (European flounder). and Clupea harengus L. (bream) from the Polish market were investigated. The total mercury was processed with AAS. The fatty acids were analyzed by gas chromatography. The concentration of mercury in muscles varied from 0.006 to 0.138 mg/kg and decreased as follows: perch ≈ ide > flounder > herring ≈ bream ≈ rainbow trout > carp ( p ≤ 0.05). There were only significant positive correlations between body weight and mercury content in muscle tissue of carp (r = 0.878), flounder (r = 0.925) and herring (r = 0.982) ( p ≤ 0.05). The atherogenic index (AI), thrombogenicity index (TI) and flesh-lipid quality index (FLQ) were calculated as follows 0.33-0.70 (IA), 0.16-0.31 (IT) and 13.01-33.22 (FLQ). Hypocholesterolemic (OFA) and hypercholesterolemic fatty acids (DFA) in muscles of fish ranged from 18.26 to 23.01 and from 73.91 to 78.46, respectively. In most cases, there were not significant correlations between size (body weight and total length) and fatty acids in the muscles of the examined fish ( p > 0.05). The Target Hazard Quotient (THQ) values were below 1, which shows that there is no non-carcinogenic health risk to the consumer by consuming the examined fish.

    The aim of this study was to investigate the prevalence and characterization of Listeria species and Listeria monocytogenes isolated from raw fish and open-air fish market environments. Eight hundred and sixty two samples including raw fish and fish market environments (samples from workers' hands, workers' knives, containers and work surface) were collected from the open-air fish markets in the Northern region of Iran. Listeria spp. was isolated from 104/488 (21.3%) raw fish and 29/374 (7.8%) of samples from open-air fish market environment. The isolates of Listeria spp. included L. innocua (35.3%), L. monocytogenes (32.3%), L. seeligeri (18%), and L. ivanovii (14.3%). Of the 43 L. monocytogenes isolates, 31 (72.1%), 10 (23.3%) and 2 (4.7%) belonged to serovars 1/2a, 4b, and 1/2b, respectively. The inlA, inlB, inlC, inlJ, actA, hlyA, iap, plcA, and prfA virulence-associated genes were detected in almost all of the L. monocytogenes isolates. The Listeria spp. isolates showed high resistance against tetracycline (23.3%), penicillin G, and cephalothin (each 16.5%). Besides, we observed significant resistance level to tetracycline (27.9%), ampicillin (20.9%), cephalothin, penicillin G, and streptomycin (each 16.3%) in the L. monocytogenes isolates. All of the isolates were susceptible to cefotaxime, gentamicin, kanamycin, and pefloxacin. We found that tetM (25.6%), tetA (23.3%), ampC (14%), and penA (11.6%) were the most prevalent antibiotic resistance genes in the L. monocytogenes isolates. Recovery of potentially pathogenic L. monocytogenes from raw fish and environment of open-air fish market samples in this study is a convincing evidence for the zoonotic potential of listeriosis.

    Market demand is often ignored or assumed to lead uniformly to the decline of resources. Yet little is known about how market demand influences natural resources in particular contexts, or the mediating effects of biological or institutional factors. Here, we investigate this problem by examining the Pacific red snapper (Lutjanus peru) fishery around La Paz, Mexico, where medium or “plate-sized” fish are sold to restaurants at a premium price. If higher demand for plate-sized fish increases the relative abundance of the smallest (recruit size class) and largest (most fecund) fish, this may be a market mechanism to increase stocks and fishermen’s revenues. We tested this hypothesis by estimating the effect of prices on the distribution of catch across size classes using daily records of prices and catch. We linked predictions from this economic choice model to a staged-based model of the fishery to estimate the effects on the stock and revenues from harvest. We found that the supply of plate-sized fish increased by 6%, while the supply of large fish decreased by 4% as a result of a 13% price premium for plate-sized fish. This market-driven size selection increased revenues (14%) but decreased total fish biomass (−3%). However, when market-driven size selection was combined with limited institutional constraints, both fish biomass (28%) and fishermen’s revenue (22%) increased. These results show that the direction and magnitude of the effects of market demand on biological populations and human behavior can depend on both biological attributes and institutional constraints. Fisheries management may capitalize on these conditional effects by implementing size-based regulations when economic and institutional incentives will enhance compliance, as in the case we describe here, or by creating compliance enhancing conditions for existing regulations.

    The Fish Barcode of Life campaign involves a broad international collaboration among scientists working to advance the identification of fishes using DNA barcodes. With over 25% of the world's known ichthyofauna currently profiled, forensic identification of seafood products is now feasible and is becoming routine. Driven by growing consumer interest in the food supply, investigative reporters from five different media establishments procured seafood samples (n = 254) from numerous retail establishments located among five Canadian metropolitan areas between 2008 and 2010. The specimens were sent to the Canadian Centre for DNA Barcoding for analysis. By integrating the results from these individual case studies in a summary analysis, we provide a broad perspective on seafood substitution across Canada. Barcodes were recovered from 93% of the samples (n = 236), and identified using the Barcode of Life Data Systems "species identification" engine ( www.barcodinglife.org ). A 99% sequence similarity threshold was employed as a conservative matching criterion for specimen identification to the species level. Comparing these results against the Canadian Food Inspection Agency's "Fish List" a guideline to interpreting "false, misleading or deceptive" names (as per s 27 of the Fish Inspection regulations) demonstrated that 41% of the samples were mislabeled. Most samples were readily identified; however, this was not true in all cases because some samples had no close match. Others were ambiguous due to limited barcode resolution (or imperfect taxonomy) observed within a few closely related species complexes. The latter cases did not significantly impact the results because even the partial resolution achieved was sufficient to demonstrate mislabeling. This work highlights the functional utility of barcoding for the identification of diverse market samples. It also demonstrates how barcoding serves as a bridge linking scientific nomenclature with approved market names

    Full Text Available This research investigated the adoption of smoking chokor among fish processors in Kwara state, Nigeria. The study made use of structured questionnaire along with interview schedule to a sample size of one hundred and seventy (170 processors randomly selected through a two-stage random sampling technique. The data were analyzed with descriptive and inferential statistics and the Regression Analysis. The results obtained through the analysis revealed that 43.7% of the respondents adopted the improved technology (smoking chokor. A higher percentage of respondents preferred the improved technology for the golden brown colour, fine texture, good smell and delicacy in the taste. The significant determinants of adoption include sex (female, income from fish processing activities (p<0.05 and the trust worthiness of the source of the technology (p<0.1. Perceived benefits associated with technology adoption include wastage reduction, employment generation and the reduction of smoke, while the technicalities associated with the use constitute a major constraint limiting its adoption. The study concludes that fish processors prefer the smoking chokor but its adoption is marred with various constraints. It therefore recommends the need for creating more awareness of the smoking chokor as well as reducing the perceived constraints limiting its adoption by training extension agents and other verifiable sources to educate farmers as they disseminate the technology.

    Full Text Available The conducted researches allowed to establish that intensive disintegration of a muscular glycogen leads to sharp decrease in size рН muscular tissue in the sour party that in turn affects a chemical composition and physic-colloidal structure of proteins therefore: resistance of meat of fish to action of putrefactive microorganisms increases; solubility of muscle proteins, level of their hydration which is water connecting abilities decreases; there is a swelling of collagen of connecting fabric; activity of the cathepsin (an optimum рН 5,3 causing hydrolysis of proteins at later stages of an autolysis increases; the bicarbonate system of muscular tissue with release of carbon dioxide collapses; predecessors of taste and aroma of meat are formed; process of oxidation of lipids becomes more active. As a result of accumulation dairy, phosphoric and other acids in meat of fish concentration of hydrogen ions of that decrease рН is result increases. Sharply shown sour environment and availability of inorganic phosphorus is considered the reason of disintegration of an actin-myosin complex on actin and a myosin which begins after 8 hours of storage, i.e. there comes the period of relaxation of muscle fibers and the period of permission of an numbness, and then the last stage of maturing of meat – deep autolysis. Thus, on the basis of classical ideas of biochemical changes of meat of land animals and summarizing the obtained data on posthumous changes in muscular tissue of fishes, it is possible to draw a conclusion that they have similar nature of regularity in comparison with muscular tissue of land animals, but their main difference is higher speed of course of autolytic transformations. It in turn leads to faster change of FTS of meat of fishes who are the defining indicators when developing assortment groups of products taking into account stages of an autolysis in meat.

    The decline in marine and freshwaters catches in recent years in Colombia has led to a change in dietary habits, with an increase in the purchase and consumption of imported fish. This is of particular concern as fish are sometimes caught in mercury-contaminated waters, and are subsequently sold canned or uncanned. In addition, canned tuna has received little attention as it is widely assumed that concentrations are low. In this study, total mercury (THg) and methylmercury (MeHg) concentrations were evaluated in three imported fish species marketed in Colombia, Prochilodus lineatus, Prochilodus reticulatus, and Pangasianodon hypophthalmus, plus four brands of canned tuna and one of sardines. One brand of tuna showed the highest mean concentrations of THg (0.543 ± 0.237 μg/g, wet weight, ww) and MeHg (0.518 ± 0.337 μg/g ww), while concentrations in P. hypophthalmus were approximately 30 times lower (≈0.02 µg/g ww). The estimated weekly intake (EWI) in children was above the provisional tolerable weekly intake (PTWI) of MeHg established by the Joint FAO/World Health Organization (WHO) Expert Committee on Food Additives (JECFA) in 2007, 1.6 μg/kg body weight (bw) per week, for all the canned tuna brands. Values for adults were below PTWI, whereas for women of childbearing age, values were above PTWI only for brand D of canned tuna. The estimate of the potential risk indicated that MeHg levels in canned tuna can generate negative effects in vulnerable groups, while the EWI of fresh fish did not pose a threat to the general population. Therefore, establishing strategies to address the high consumption of canned tuna, and continuous monitoring to control commercial food, are recommended to decrease Hg exposure.

    "TSUKIJI" is one of the biggest and most famous Free Fish Markets in the world, but there are many problems on the working condition because it was built about 60 years ago. Our investigation was held 1991 to 1993 to give some improvements regarding layout of buildings, working time, heat condition at refrigerator, working posture, and so on. We used a questionnaire on daily life and health care of workers, time study with measurement of heartbeats, and checklist (using Checklist for Improvement of Safety-Health and Working Conditions,' made by ILO). The main occupations in TSUKIJI were seller, buyer, delivery worker, and refrigerator maintenance worker. Their starting time was early in the morning, usually between 2:00 a.m. and 5:00 a.m., but the hardest one was delivery workers starting at 9:00 p.m. They used auto cargo car for carrying to shops from refrigerator or from auction places many times. Sellers had two different types of work. First, the seller set up the auction, numbering the fish (or cases of seafood), arranging them in order, and so on. The rest of the work was transaction of invoices, sometimes using VDU with almost sitting. These works did not look well balanced. Buyer of tuna cut if like lumber by electric saws did not have guard for protection and there were more than 200 machines. Overlooking the market by checklist, some problems were clarified, and suggestions for improvement include restructuring the whole layout of the market or reforming buildings, standardization of the cases, adjustment of health facilities, safety protection on tools and machines, management of working system, working posture, health care, and so on.

    Full Text Available In order to improve the encapsulation process, a newly supercritical antisolvent process was developed to encapsulate fish oil using hydroxypropyl methyl cellulose as a polymer. Three factors, namely, temperature, pressure, and feed emulsion rate were optimized using response surface methodology. The suitability of the model for predicting the optimum response value was evaluated at the conditions of temperature at 60°C, pressure at 150 bar, and feed rate at 1.36 mL/min. At the optimum conditions, particle size of 58.35 μm was obtained. The surface morphology of the micronized fish oil was also evaluated using field emission scanning electron microscopy where it showed that particles formed spherical structures with no internal voids. Moreover, in vitro release of oil showed that there are significant differences of release percentage of oil between the formulations and the results proved that there was a significant decrease in the in vitro release of oil from the powder when the polymer concentration was high.

    White, K R; Thompson, J M; Patel, U B

    2001-01-01

    The hospital marketing function has been widely adopted as a way to learn about markets, attract sufficient resources, develop appropriate services, and communicate the availability of such goods to those who may be able to purchase such services. The structure, tasks, and effectiveness of the marketing function have been the subject of increased inquiry by researchers and practitioners alike. A specific understanding of hospital marketing in a growing managed care environment and the relationship between marketing and managed care processes in hospitals is a growing concern. Using Kotler and Clarke's framework for assessing marketing orientation, we examined the marketing orientation of hospitals in a single state at two points in time--1993 and 1999. Study findings show that the overall marketing orientation score decreased from 1993 to 1999 for the respondent hospitals. The five elements of the Kotler and Clarke definition of marketing orientation remained relatively stable, with slightly lower scores related to customer philosophy. In addition, we evaluated the degree to which selected managed care activities are carried out as part of its marketing function. A significant (p marketing function was evident from 1993 to 1999. With increasing numbers of managed care plan enrollees, hospitals are likely focusing on organizational buyers as important customers. In order to appeal to organizational buyers, hospital executives may be focusing more on clinical quality and cost efficiency in the production of services, which will improve a hospital's position with organizational buyers.

  7. Fish market surveys indicate unsustainable elasmobranch fisheries in the Saudi Arabian Red Sea

    Elasmobranch populations worldwide are severely threatened due to overexploited and unregulated fisheries. Despite the fact that sharks and rays are captured in fisheries operating along the Red Sea coast of the Kingdom of Saudi Arabia (KSA), information on any aspects of these fisheries are very limited. Here we document the structure, composition and biological characteristics of eastern Red Sea elasmobranch fisheries based on genetic identification and market survey data over an intensive two-year sampling period at the biggest Red Sea fish market in the KSA (Jeddah). Market surveys conducted two times per month between 2011 and 2013 revealed that 24 previously confirmed elasmobranch species for the Red Sea were landed by fishers and offered for sale. Genetic identification revealed two potentially undescribed guitarfish species as well as four batoid species not formerly reported from the Red Sea. Five coastal carcharhinid species dominated the landings-. Carcharhinus sorrah, C. amblyrhynchos, C. falciformis, C. limbatus, Rhizoprionodon acutus, together comprising 73% numerically of the total catch. Targeted shark fisheries reportedly exist in shark nursery areas. Most elasmobranchs outside of these areas were reportedly landed as bycatch. Most strikingly, the large majority of landed elasmobranchs were immature males or females below their reported size of sexual maturity, which suggests potential for both growth and recruitment overfishing and emphasizes the urgent need to implement region-specific management and conservation strategies to avoid the loss of these critical predators.

    Full Text Available Mussels filter large volumes of water and can concentrate pathogenic organisms, which may act as potential vehicles of transmission to the consumer. A survey study was carried out to investigate the presence of Cryptosporidium protozoan parasites in green mussels (Perna viridis, the smussles pecies most destined for consumption in Thailand. In total, 56 samples were examined from Bangkok (n = 24 and Samut Prakan (n = 32 a wholesale shell-fish markets located at the mouth of the Chao Phraya River. The market for green mussels was closed to the mussel culture placed along the coastal line and this localization may have significant economical impact if the mussels’ cultures are found contaminated. Cryptosporidium spp. oocysts were detected by the immunofluorescence antibody method (IFA in 12.5% of the samples examined. The detection of Cryptosporidium oocysts in green mussels’ population of Samut Prakan was higher (15.6% than in Bangkok market (8.3%. These differences in positive samples from the two locations may be caused by physical, ecological and anthropogenic conditions. This could relay to different contamination levels of marine water by Cryptosporidium oocysts and consequently to contamination of harvested shellfish populations. The results demonstrate that the Cryptosporidium spp. oocysts were found indigenous in mussels from the coastal line of Thailand, indicating that mussels may act as a reservoir of Cryptosporidium foodborne infections for humans.

    Full Text Available Summary. Competitive advantages of this direction of researches are in justification of actions and offers on a technical provision of production of a dry fish basis from meat- and bone residue of pond fishes that will allow to produce fast foods of high quality and biological value (broths, soups, sauces, to expand the assortment taking into account market demand, to introduce the new forms of food convenient in storage and use at home and outside as well as for special food. The first courses on dry fish broth are easily digestible, with the high contents of micro and macro elements in the quantity of them they surpass meat broths. Their other advantage is the content of the polynonsaturated fatty acids neutralizing negative impact of substances, destroying tendons, ligaments and cartilage in the human body, thereby eliminating joint pains that is especially important for the determined groups of the population, for example, the military personnel, sportsmen, etc. In addition, this technology includes sparing modes of processing of raw materials, keeping thereby native properties of useful substances (protein, fat as much as possible. Researches on selection of an optimum ratio of the heads and the bones providing high organoleptic rates of broths on their basis were carried out to produce dry fish bases. Conditions and parameters of convective drying of little value products of cutting of silver carp and cod are determined. The results allow to draw a preliminary conclusion on the possibility of creation a new technology of powdery products for broths fast preparation. The developed technology is of great importance in the creation of waste-free and low-waste production at the enterprises of fishery industry of the Russian Federation.

    The aim of this survey was to compare total mercury (THg) in canned fish in terms of species and fishing area. A number of 110 samples of canned fish, which were divided by fish species and fishing area, were analysed. The highest THg content in muscle tissue was found in the escolar. In other fish species, the highest level was detected in tuna. Mercury content in tuna differed significantly from mackerel, sardine, and sprat. Mercury content in herring differed significantly from sprat. The order of the fish according to their THg content corresponds to their status in the aquatic food chain. A significant difference was also found between fish caught from the closed Mediterranean and Black Sea and fish caught in the open oceans. In terms of THg content, the results of this study indicate good quality of various species of canned fish caught in worldwide locations.

    1979-09-01

    This report is a synthesis of published work on the contamination of fish by radiostrontium, covering 143 publications and reports. The authors highlight the most important findings, since past activity levels in fish allow the effects of future discharges to be estimated. Both marine and freshwater environments are analyzed. The radiostrontium activity is evaluated in fish from zones both directly and not directly affected by liquid effluent discharges. Quantitative data is cited for the concentration factors and biological half lives determined from field measurements and laboratory experiments. Physiological phenomena discussed include contamination kinetics, radiostrontium distribution in fish organisms and the extent of transfer through food chains. The effects of biological factors (age, weight, species) and environmental factors (temperature, salinity, influence of stable elements) are examined. The radiostrontium uptake potential is higher in fresh water fish than in marine fish. In both cases, however, the water itself is the principal contamination source, and food is not of major importance; only the intake path varies. In both freshwater and seawater areas not directly affected by waste discharge, the 90 Sr content in fish was observed to rise until 1966, when it began to drop. Maximum values of 42000 pCi/kg live weigth were recorded in the skeletons of lacustrine fish. The mean concentration factors are 20 for marine fish and 300 for freshwater fish, while the biological half-lives are 138 days and 2 years, respectively. This bibliographic synthesis clearly demonstrates the need to determine baseline conditions prior to reactor divergence, and to make sufficient allowance for the local ecological characteristics of each site [fr

    Empirical analysis of the price fluctuations of financial markets has received extensive attention because a substantial amount of financial market data has been collected and because of advances in data-mining techniques. Price fluctuation trends can help investors to make informed trading decisions, but such decisions may also be affected by a psychological factors-the anchoring effect. This study explores the intraday price time series of Taiwan futures, and applies diffusion model and quantitative methods to analyze the relationship between the anchoring effect and price fluctuations during first passage process. Our results indicate that power-law scaling and anomalous diffusion for stock price fluctuations are related to the anchoring effect. Moreover, microscopic price fluctuations before switching point in first passage process correspond with long-term price fluctuations of Taiwan's stock market. We find that microscopic trends could provide useful information for understanding macroscopic trends in stock markets.

    2013-01-01

    Polonium-210 (t 1/2 = 138 d) is a decay product of uranium-radium decay chain and consequently widely spread in the environment. It enters organisms through direct uptake, ingestion or inhalation. It is a pure alpha emitter and its radiotoxicity is connected with the fact that emits alpha particles with relatively high energy of about 5.3 MeV. It is concentrated in the soft tissues such as mussel, liver and others, where significantly contributes to the internal dose. Beta emitter lead-210 (t 1/2 = 22.17 years) is the second highest radiotoxic radionuclide from uranium-238 decay chain and decays, through bismuth- 210 (t 1/2 = 5.01 d) into 210 Po. Therefore it is necessary to determine the 21P o in foods, especially in seafood, because of its accumulation capacity. 210 Po and 210 Pb were determined in mussels (Mytilus galloprovincialis) and fish (salmon, trout) from Slovenia market. Mussels were bought on the local market as well as from domestic producers. Fish of Slovenian origin were bought on the local market. Samples were freeze dried, homogenized and assayed for 210 Po and 210 Pb. First, radiochemical separation was performed, followed by alpha particle spectrometric measurement of 210 Po and beta counting of 210 Pb on a low background gas-flow proportional counter. The results obtained show that the activity concentrations of 210 Po in mussels varied from 0.9 to 191 Bq/kg of fresh mass and for fish from 0.3 to 2.12 Bq/kg of fresh mass, while for 210 Pb they varied from 1.5 to 6.9 Bq/k of fresh mass for mussels and in fish samples the activity concentrations were less than 1.9 Bq/kg of fresh mass. Combined annual ingestion doses due to 210 Po and 210 Pb for mussels and fish from the Slovenian market is assessed. (author)

    Full Text Available Monitoring of protein breakdown products and lipid autoxidation in farmed mullet fish as a function of a proposed treatments prior to chilling process at 3 °C ± 1 was carried out. Furthermore, sensory evaluation of three investigated treatments, whole mullet fish (RM-eviscerated and soaked in distilled water (WSRM-eviscerated and soaked in a solution containing 5% K-sorbate + 5% Na4P2O7 + 2% Na-citrate + 0.2% ascorbic acid (SSRM, were followed during chilling storage. Estimation of the predicted length of cold storage period as well as the marketing losses of the marketable mullet fish was also elucidated. The marketing losses of mullet fish at whole or retail market levels were also estimated by using a pre-tested questionnaire. Total volatile basic nitrogen (TVB-N and trimethylamine nitrogen (TMA-N increased concomitantly during cold storage of differently treated mullet fish. Moreover, lipid oxidation and hydrolysis products were followed by determining peroxide value (PV, thiobarbituric acid reactive substances (TBARS and ratio of absorbance (A400/A450 as well as acid value (AV and free volatile fatty acids (FVFA. Mostly, these parameters show upward trend with different rates depending on the applied treatment. Soaking treatment greatly retarded fish spoilage during cold storage. As regards, SSRM samples withstand spoilage up to about 15 days compared to only 8 and 9 days for both RM and WSRM samples, respectively.

  13. The Action Research Process and Matrix Marketing

    Directory of Open Access Journals (Sweden)

    Claudio Vignali

    2001-01-01

    Full Text Available There has been extensive and long-lasting debate in the UK about the purpose and scope of appropriate management research. Many authors elucidate that it is widely agreed that management research does not operate a single agreed scientific paradigm and can be seen as a soft, applied area of study, showing features of both, ‘engineering’ and ‘craft’ orientations. Nevertheless, the need for management theory to be made more relevant to the work of practice by explaining that it will be necessary to identify new ways of formulating and employing scientific knowledge to practical ends is the basis of this work. However, some authors argue that the process of managerial decision-making, a major aspect of the strategic planning procedure, has become more problematic because modern management, more than ever before, is faced with an immense complexity of tasks and an increasingly volatile business environment. For many years writers have been suggesting that organisations should focus and rely on the fundamental formal models and techniques of strategic planning.

    Ciguatera fish poisoning (CFP) is a common intoxication associated with the consumption of reef fish, which constitutes a critical issue for public health in many countries. The complexity of its epidemiology is responsible for the poor management of the risk in tropical fish markets. We used the example of the Noumea fish market in New Caledonia to develop a cost-effective methodology of assessing the CFP risk. We first used published reports and the knowledge of local experts to define a list of potentially poisonous local species, ranked by their ciguatoxic potential. Based on two 1-month surveys in the market, conducted in winters 2008 and 2009, we then calculated the consolidated ratio of biomass of potentially poisonous species vs. total biomass of fish sold on the market. The prevalence of high CFP-risk species in the market was 16.1% and 18.9% in 2008 and 2009, respectively. The most common high CFP risk species were groupers (serranids), king mackerels (scombrids), snappers (lutjanids), barracudas (sphyaraenids), emperors (lethrinids) and wrasses (labrids). The size (age) of the fish also plays a critical role in the potential ciguatoxic risk. According to proposals of average size thresholds provided by experts for high-risk species, we were also able to assess the additional risk induced by the sale of some large fish on the market. The data collected both from experts and from the market allowed us to develop a cost-effective proposal for improving the management of the CFP risk in this market. However, the successful implementation of any regulation aiming to ban some specific species and sizes from the market, with an acceptable economical impact, will require the improvement of the expertise in fish identification by public health officers and, ideally, the commitment of retailers.

    Full Text Available Sustainability has become a necessity in the building industry. In recent years, as the general public is more informed and aware of sustainability related issues, they are becoming major players in the decision making process regarding their built environment. However, there are still challenges with how sustainability is communicated to occupants and owners of buildings. As the global economic crisis is continuing, the marketing of green buildings needs to be refined to communicate the lifetime benefits of sustainability. One of the ways to develop effective marketing strategies, is to understand what the occupants value the most among many aspects of green buildings thus develop focused marketing solutions. Authors present a conceptual methodology using Analytic Hierarchy Process toward identifying consumer ranking and weights of a major green building rating system’s categories. Authors use sample non-representative data to illustrate the proposed methodology, while sharing preliminary qualitative data from the research in progress.

    1992-01-01

    This paper reports that American Electric Power Service Corporation has explored the feasibility of using a patented signal development process and underwater sound system to divert fish away from water intake areas. The effect of water intakes on fish is being closely scrutinized as hydropower projects are re-licensed. The overall goal of this four-year research project was to develop an underwater guidance system which is biologically effective, reliable and cost-effective compared to other proposed methods of diversion, such as physical screens. Because different fish species have various listening ranges, it was essential to the success of this experiment that the sound system have a great amount of flexibility. Assuming a fish's sounds are heard by the same kind of fish, it was necessary to develop a procedure and acquire instrumentation to properly analyze the sounds that the target fish species create to communicate and any artificial signals being generated for diversion

    Full Text Available Heavy metals entrance to fish body tissues and transferring to human body systems after their consuming makes numerous undesirable effects and health problems. The aim of this study was to determine some heavy metals (lead, cadmium and mercury in fresh fishes marketed in Khorramabad City, west of Iran. In this descriptive study, five samples of 17 fish species with high consumption were purchased randomly in 2014. Measurement of mercury, lead and cadmium was performed using atomic absorption spectrometry. All measurements were performed three times for each sample. Lead mean levels in fish samples was in the range 0.736 -1.005 ppm, cadmium range was from 0.196 to 0.015 ppm and mean content of mercury was  0.431 - 0.107 ppm. At present mean concentration of lead, mercury and cadmium in supplied fishes muscle is lower than maximum recommended levels according to WHO, EC and FDA guidelines. Based on the obtained results of this study and the importance of heavy metals in foods and their impacts on human health, continuous monitoring of heavy metals levels in foods is necessary.

    The purpose of vocational rehabilitation (VR) is to provide disabled individuals with the training and support services needed to assimilate into the workforce. This study incorporates concepts developed in the relationship marketing and internal marketing literature to determine the factors that influence overall satisfaction of vocational training services. Results underscore the importance of social and structural bonds that develop among the multiple stakeholders involved in the VR process. Satisfaction is also influenced by the design and equipment used in the facilities and the efficiency of initiating VR services. A highly reliable instrument to measure VR participant satisfaction is presented.

    Selection of a power market structure from the available alternatives is an important activity within an overall power sector reform program. The evaluation criteria for selection are both subjective as well as objective in nature and the selection of alternatives is characterised by their conflicting nature. This study demonstrates a methodology for power market structure selection using the analytic hierarchy process, a multiple attribute decision- making technique, to model the selection methodology with the active participation of relevant stakeholders in a workshop environment. The methodology is applied to a hypothetical case of a State Electricity Board reform in India. (author)

    The concentrations of the heavy metals cadmium (Cd), mercury (Hg), lead (Pb), chromium, silver, nickel, copper, and zinc in the edible portions of 105 marine invertebrates representing 16 mollusk and crustacean species were accurately determined to evaluate their hazard for human consumption. The samples were collected in 2011 from major fish markets on the coast of Korea and analyzed for Hg using a direct Hg analyzer and for other metals using inductively coupled plasma mass spectrometry. Estimated dietary exposure (EDE) was determined, and a risk assessment was made of the heavy metals to provide information concerning consumer safety. The Cd concentrations, which were the highest for the three hazardous metals (Cd, Hg, and Pb), were significantly higher (P Food Additives or the U.S. Environmental Protection Agency. The EDE of Cd, Hg, and Pb for each class of marine invertebrate were 0.07 to 2.64, 0.01 to 0.43, and 0.001 to 0.16% of the PTDI, respectively. The total EDE of Cd, Hg, and Pb for marine invertebrates accounted for 4.03, 0.96, and 0.21%, respectively, of the PTDI. The EDE of other metals in each class of marine invertebrate was less than 2% of the PTDI. The hazard index is a reasonable parameter for assessing the risk of heavy metal consumption associated with contaminated food. In the present study, the hazard index for all of the species was less than 1.0, which indicates that the intake of heavy metals from consumption of these marine invertebrates does not represent an appreciable hazard to humans.

    Full Text Available This paper put on few reflexions emerged from ethnographies on islands on the mouth of Amazon river: Capim island, in Abaetetuba and Apeú Salvador, located in Viseu. We analyzed few features related to the fisheries market in which are the habitants of these islands. The ethnography allows us a rich dialogue with theories towards the analyze of the process involving these small fishworkers, mainly theirs commercial affairs, that include larger than monetarist links. In that region fishery is a very important activity not only by supply food directly to people but in their sole commercial production. Grosso modo, all fishermen in small scales are designated by the term 'artisanal', and we suggest thereway that the simplist opposition from 'artisanal' to industrial fishery, reduce the specificities and particular fields of the production, leading to an idea of homogeneity in the activity. What we want is just point put the complexity and diversification of social organization in which group of fishermen, in accord with each empiric reality.

    Food-processing techniques may induce changes in fish protein immunogenicity. Allergens from >100 fish species have been identified, but little is known on the effects of processing on fish protein immunogenicity. IgE binding of sera of patients allergic to fresh and processed (smoked, salted/sugar-cured, canned, lye-treated and fermented) cod, haddock, salmon, trout, tuna, mackerel and herring and of hydrolysates based on salmon and whiting was investigated using immunoblot and inhibition ELISA. Parvalbumin oligomers were identified using monoclonal and polyclonal antibodies. IgE binding was seen in most sera at 12-14 kDa (parvalbumin), and at 17-60 kDa for all fish except tuna. Changes in IgE binding appeared to reflect altered parvalbumin monomers and oligomers. Smoked haddock, salmon and mackerel had increased IgE binding and novel bands at 30 kDa. Chemically processed cod, salmon, trout and pickled herring had reduced or abolished IgE binding. The serum of 1 subject, however, had increased IgE binding to these products and also inhibition of binding by both fish hydrolysates to their constituent fish species. Process-induced changes in fish protein immunogenicity were more dependent on process rather than species, although individual responses varied. Changes in the allergenicity of a product may depend on the net effect of processing on parvalbumin oligomerization patterns, which may also vary in different species. Chemical processes generally caused loss in IgE-binding activity, though sensitization may occur to modified or degraded rather than intact peptides as shown by increased binding by chemically processed fish and hydrolysates in 1 subject. The clinical significance of these findings remains to be established.

  10. Climate variability and change scenarios for a marine commodity: Modelling small pelagic fish, fisheries and fishmeal in a globalized market

    The world's small pelagic fish populations, their fisheries, fishmeal and fish oil production industries and markets are part of a globalised production and consumption system. The potential for climate variability and change to alter the balance in this system is explored by means of bioeconomic models at two different temporal scales, with the objective of investigating the interactive nature of environmental and human-induced changes on this globalised system. Short-term (interannual) environmental impacts on fishmeal production are considered by including an annual variable production rate on individual small pelagic fish stocks over a 10-year simulation period. These impacts on the resources are perceived by the fishmeal markets, where they are confronted by two aquaculture expansion hypotheses. Long-term (2080) environmental impacts on the same stocks are estimated using long-term primary production predictions as proxies for the species' carrying capacities, rather than using variable production rates, and are confronted on the market side by two alternative fishmeal management scenarios consistent with IPCC-type storylines. The two scenarios, World Markets and Global Commons, are parameterized through classic equilibrium solutions for a global surplus production bioeconomic model, namely maximum sustainable yield and open access, respectively. The fisheries explicitly modelled in this paper represent 70% of total fishmeal production, thus encapsulating the expected dynamics of the global production and consumption system. Both short and long-term simulations suggest that the sustainability of the small pelagic resources, in the face of climate variability and change, depends more on how society responds to climate impacts than on the magnitude of climate alterations per se.

    An assessment of Committed Effective Dose (CED) due to consumption of Red Sea fish containing 210 Po and 137 Cs was performed for 23 different marine fish samples collected from the local market at Port Sudan. The fish were classified according to their feeding habits into three categories: carnivores, herbivores, and omnivores. Measured activity concentrations of 210 Po were found in the ranges 0.25-6.42 (carnivores), 0.7-5 (omnivores) and 1.5-3.8 (herbivores) Bq/kg fresh weight. In the same study, activity concentrations of Cs-137 were determined to be in the ranges 0.1-0.46 (carnivores), 0.09-0.35 (omnivores) and 0.09-0.32 (herbivores) Bq/kg fresh weight, which were several times lower than those of 210 Po. Appropriate conversion factors were used to derive the CED, which was found to be 0.012, 0.01 and 0.01 (μSv/yr) in carnivores, omnivores and herbivores, respectively, for 137 Cs. This contributes about 0.4% of the total dose exclusively by ingestion of fish. For 210 Po, it was found to be 3.47, 4.81 and 4.14 (μSv/yr) in carnivores, omnivores and herbivores, respectively, which represents 99.6% of the total dose (exclusively by ingestion of fish). The results of CED calculations suggest that the dose received by the Sudanese population from the consumption of marine fish is rather small and that the contribution of 137 Cs is negligible compared to 210 Po

    The increasing consumption of shark products, along with the shark's fishing vulnerabilities, has led to the decrease in certain shark populations. In this study we used a DNA barcoding method to identify the species of shark landings at fishing ports, shark fin products in retail stores, and shark fins detained by Taiwan customs. In total we identified 23, 24, and 14 species from 231 fishing landings, 316 fin products, and 113 detained shark fins, respectively. All the three sample sources were dominated by Prionace glauca, which accounted for more than 30% of the collected samples. Over 60% of the species identified in the fin products also appeared in the port landings, suggesting the domestic-dominance of shark fin products in Taiwan. However, international trade also contributes a certain proportion of the fin product markets, as four species identified from the shark fin products are not found in Taiwan's waters, and some domestic-available species were also found in the customs-detained sample. In addition to the species identification, we also found geographical differentiation in the cox1 gene of the common thresher sharks (Alopias vulpinus), the pelagic thresher shark (A. pelagicus), the smooth hammerhead shark (Sphyrna zygaena), and the scalloped hammerhead shark (S. lewini). This result might allow fishing authorities to more effectively trace the origins as well as enforce the management and conservation of these sharks.

    Flow regimes are important drivers of both stream community and biogeochemical processes. However, the interplay between community and biogeochemical responses under different flow regimes in streams is less understood. In this study, we investigated the structural and functional responses of periphyton and macroinvertebrates to different densities of the Mediterranean barbel (Barbus meridionalis, Cyprinidae) in two stream reaches differing in flow regime. The study was conducted in Llémena Stream, a small calcareous Mediterranean stream with high nutrient levels. We selected a reach with permanent flow (permanent reach) and another subjected to flow regulation (regulated reach) with periods of flow intermittency. At each reach, we used in situ cages to generate 3 levels of fish density. Cages with 10 barbels were used to simulate high fish density (>7indm -2 ); cages with open sides were used as controls (i.e. exposed to actual fish densities of each stream reach) thus having low fish density; and those with no fish were used to simulate the disappearance of fish that occurs with stream drying. Differences in fish density did not cause significant changes in periphyton biomass and macroinvertebrate density. However, phosphate uptake by periphyton was enhanced in treatments lacking fish in the regulated reach with intermittent flow but not in the permanent reach, suggesting that hydrologic alteration hampers the ability of biotic communities to compensate for the absence of fish. This study indicates that fish density can mediate the effects of anthropogenic alterations such as flow intermittence derived from hydrologic regulation on stream benthic communities and associated biogeochemical processes, at least in eutrophic streams.

    Full Text Available Reliable and precise species identification is important to fisheries management and conservation. However, many rays and skates in Indonesia are currently being exploited and landed into traditional fish market without a proper identification. Therefore, this study was conducted to identify species of skates and stingrays that were landed and traded in three fish markets in Indonesia (Palabuhanratu, Muara Saban, and Lampung using molecular techniques and to determine the conservation status of the identified species based on IUCN (International Union for Conservation of Nature and Natural Resources as well as defined by CITES (Convention on International Trade in Endangered Species. The mitochondrial cytochrome oxidase I (COI gene was amplified by polymerase chain reaction (PCR using a pair of primer, fish-BCL and fish-BCH. Of 29 tissue samples collected from the study sites, a total of five species were successfully identified: Dipturus chilensis (4, Himantura walga (1, Neotrygon kuhlii (11, Taeniura lymma (9 and Rhinoptera javanica (4. The Neighbor Joining phylogeny of mitochondrial lineages, based on partial COI gene sequences, the ingroup haplotypes were clustered into five main clades representing each species. The identified stingrays were being listed as vulnerable (D. chilensis and R. javanica, near threatened (H. walga and T. lymma, and data deficient (N. kuhlii by IUCN, with two species (D. chilensis and H. walga population were indicated decreased. Unfortunately, all of identified species have not been evaluated by CITES regarding their trade status. As a consequences, a valuable effort should be placed to create a scientific network for monitoring programmes not only on a local scale, and to make pressure on governments for adopting molecular techniques as tools for controlling and avoiding misidentification.

    A non-destructive method of estimating the freshness of fish is required for appropriate price setting and food safety. In particular, for determining the possibility of eating raw fish (sashimi), freshness estimation is critical. We studied such an estimation method by capturing images of fish eyes and performing image processing using the temporal changes of the luminance of pupil and iris. To detect subtle non-visible changes of these features, we used UV (375 nm) light illumination in addition to visible white light illumination. Polarization and two-channel LED techniques were used to remove strong specular reflection from the cornea of the eye and from clear-plastic wrap used to cover the fish to maintain humidity. Pupil and iris regions were automatically detected separately by image processing after the specular reflection removal process, and two types of eye contrast were defined as the ratio of mean and median pixel values of each region. Experiments using 16 Japanese dace (Tribolodon hakonensis) at 23° and 85% humidity for 24 hours were performed. The eye contrast of raw fish increase non-linearly in the initial period and then decreased; however, that of frozen-thawed fish decreased linearly throughout 24 hours, regardless of the lighting. Interestingly, the eye contrast using UV light showed a higher correlation with time than that using white light only in the case of raw fish within the early 6- hour period postmortem. These results show the possibility of estimating fish freshness in the initial stage when fish are eaten raw using white and UV lightings.

    Full Text Available Diarrhea is one of the most common diseases and is a leading cause of death in developing countries. This is often caused by contaminated food. Poor food hygiene standards are exacerbated by the presence of flies which can transmit a variety of infectious microorganisms, particularly through animal source foods. This fact becomes especially important in developing countries like Zambia, where fish is a highly valued source of protein. Our interest in this study was to identify if the flies that beset food markets in Zambia carry important pathogenic bacteria on their bodies, and subsequently if these bacteria carry resistance genes to commonly used antibiotics, which would indicate problems in eradicating these pathogens. The present study took into account fish vendors’ and consumers’ perception of flies and interest in interventions to reduce their numbers. We conducted semi-structured interviews with (1 traders (comprised of randomly selected males and females and (2 consumers (including randomly selected males and females. Thereafter, we collected flies found on fish in markets in Mongu and Lusaka districts of Zambia. For the entire study, a total of 418 fly samples were analyzed in the laboratory and Salmonella spp. and enteropathogenic Escherichia coli were isolated from the flies. Further laboratory screening revealed that overall, 17.2% (72/418 (95% CI; 43.2%–65.5% of total samples analyzed contained Extended-Spectrum Beta-Lactamase (ESBL-producing E. coli. These significant findings call for a strengthening of the antibiotic administering policy in Zambia and the development of sustainable interventions to reduce fly numbers in food markets and improve food safety and hygiene.

    The first food product commercially produced by a U.S. company using high-pressure processing has had successful test market results. High-pressure processing permits food to be preserved by subjecting it to pressures in the range of 60,000-100,000 psi for a short time instead of exposing the food to heat, freezing, chemicals, or irradiation. To produce Classic Guacamole, Avomex of Keller, Texas, uses a batch isostatic press to deactivate the enzymes in the avocado and to kill bacteria, obtaining a refrigerated shelf life of over 30 days. The guacamole is then vacuum packed and processed again. The product undergoes no heat treatment and does not contain preservatives, and the high pressure does not affect its texture, color, or taste. Meanwhile, a continuous system for high-pressure processing of pumpable foods is currently being developed by Flow International of Kent, Washington, and will be used for testing and applications work at Oregon State University

    The worldwide LPG industry continues to expand faster than the petroleum industry -- 4%/year for LPG vs. 2%/year for petroleum in 1995 and less than 1%/year in the early 1990s. This rapid expansion of LPG markets is occurring in virtually every region of the world, including such developing countries as China. The Far East is the focus of much of the LPG industry's attention, but many opportunities exist in other regions such as the Indian subcontinent, Southeast Asia, and Latin America. The investment climate is improving in all phases of downstream LPG marketing, including terminaling, storage, and wholesale and retail distribution. The world LPG supply/demand balance has been relatively tight since the Gulf War and should remain so. Base demand (the portion of demand that is not highly price-sensitive) is expanding more rapidly than supplies. As a result, the proportion of total LPG supplies available for price-sensitive petrochemical feedstock markets is declining, at least in the short term. The paper discusses importers, price patterns, world LPG demand, world LPG supply, US NGL supply, US gas processing, ethane and propane supply, butane, isobutane, and natural gasoline supply, and US NGL demand

These models are based on generalized telegraph processes with alternating velocities and jumps occurring at switching velocities. The model under consideration is arbitrage-free and complete if the directions of jumps in stock prices are in a certain correspondence with their velocity and with the behaviour of the interest rate. A risk-neutral measure and arbitrage-free formulae for a standard call option are constructed. This model has some features of models with memory, but it is more simple.

    Concentrations of heavy metals (As, Cd, Pb, Cu, Ni, Fe, Mn, and Zn) in market vegetables and fishes in Beijing, China, are investigated, and their health risk to local consumers is evaluated by calculating the target hazard quotient (THQ). The heavy metal concentrations in vegetables and fishes ranged from not detectable (ND) to 0.21 mg/kg fresh weight (f.w.) (As), ND to 0.10 mg/kg f.w. (Cd), and n.d to 0.57 mg/kg f.w. (Pb), with average concentrations of 0.17, 0.04, and 0.24 mg/kg f.w., respectively. The measured concentrations of As, Cd, Pb, Cu, Ni, Fe, Mn, and Zn are generally lower than the safety limits given by the Chinese regulation safety and quality standards of agriculture products (GB2762-2012). As, Cd, and Pb contaminations are found in vegetables and fishes. The exceeding standard rates are 19 % for As, 3 % for Cd, and 25 % for Pb. Pb contaminations are found quite focused on the fish samples from traditional agri-product markets. The paper further analyzed the health risk of heavy metals in vegetables and fishes respectively from supermarkets and traditional agri-product markets; the results showed that the fishes of traditional agri-product markets have higher health risk, while the supermarkets have vegetables of higher heavy metal risk, and the supervision should be strengthened in the fish supply channels in traditional agri-product markets.

The analysis of fatty acid and sugars composition were performed by gas liquid chromatography and high performance liquid chromatography, respectively. Protein and lipid content were founded higher in baked and fried in fish S. commersonnianus (74.29%, (20.20%, fish Sphyraena helleri (88.12% and (17.77%, respectively. Ash content in fish S. commersonnianus varies from 9.80% to 15.34%, and in fish S. helleri from 5.83% to 7.68%. Based on the proximate analysis, it can be calculated that an edible portion of 100 g of studied edible plant foods provides, on average, around 303.9±1.04 kcal. The plant Portulaca neglecta is suitable for high temperature food processes. The macronutrient profile in general revealed that the wild plant foods were with rich sources of protein and carbohydrates, and had low amounts of fat. The highest protein, the lowest fat and energy contents were found in boiled in both fish species; therefore, boiling can be recommended as the best cooking method for healthy diet.

    Species substitution is a form of seafood fraud for the purpose of economic gain. DNA barcoding utilizes species-specific DNA sequence information for specimen identification. Previous work has established the usability of short DNA sequences-mini-barcodes-for identification of specimens harboring degraded DNA. This study aims at establishing a DNA mini-barcoding system for all fish species commonly used in processed fish products in North America. Six mini-barcode primer pairs targeting short (127-314 bp) fragments of the cytochrome c oxidase I (CO1) DNA barcode region were developed by examining over 8,000 DNA barcodes from species in the U.S. Food and Drug Administration (FDA) Seafood List. The mini-barcode primer pairs were then tested against 44 processed fish products representing a range of species and product types. Of the 44 products, 41 (93.2%) could be identified at the species or genus level. The greatest mini-barcoding success rate found with an individual primer pair was 88.6% compared to 20.5% success rate achieved by the full-length DNA barcode primers. Overall, this study presents a mini-barcoding system that can be used to identify a wide range of fish species in commercial products and may be utilized in high throughput DNA sequencing for authentication of heavily processed fish products.

    Fish is one of the most common causes of food allergy and its major allergen is parvalbumin, a 12 kDa muscular protein. In this study, a sandwich enzyme-linked immunosorbent assay (ELISA) for the determination of fish protein in processed foods was developed using a polyclonal antibody raised against Pacific mackerel parvalbumin. The developed sandwich ELISA showed 22.6-99.0% reactivity (based on the reactivity to Pacific mackerel parvalbumin) to parvalbumins from various species of fish. The limits of detection and quantitation were estimated to be 0.23 and 0.70 μg protein per g of food, respectively. When the sandwich ELISA was subjected to inter-laboratory validation, spiked fish protein was recovered from five model processed foods in the range of 69.4-84.8% and the repeatability and reproducibility relative standard deviations were satisfactorily low (≤ 10.5%). Thus, the sandwich ELISA was judged to be a useful tool to determine fish protein in processed foods. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Many fish cultivator in Indonesia who suffered losses due to the sale and purchase of fish seeds did not match the agreed amount. The loss is due to the calculation of fish seed still using manual method. To overcome these problems, then in this study designed fish counting system automatically and real-time fish using the image processing based on Raspberry Pi. Used image processing because it can calculate moving objects and eliminate noise. Image processing method used to calculate moving object is virtual loop detector or virtual detector method and the approach used is “double difference image”. The “double difference” approach uses information from the previous frame and the next frame to estimate the shape and position of the object. Using these methods and approaches, the results obtained were quite good with an average error of 1.0% for 300 individuals in a test with a virtual detector width of 96 pixels and a slope of 1 degree test plane.

    Results: Housewives and employed women reported similar and sometimes different barriers for fish consumption. The barriers for non consumption were of the following: high price of fish, unpleasant taste of fish, having bone and goo, and dislike of fish by one of the family members. From the viewpoint of the employed women, being unfamiliar with cooking methods(promotion aspect, high price of fish, unpleasant taste of fish, having bone and goo, its favor, dislike of fish by one of the family members, and lack of time were reported as the most important barriers. Conclusion: People's views, demands and preferences about different issues and products such as health issues and healthy products are influenced by individual and environmental conditions including biologic condition and health level, cultural, social, political, economic and bio-environmental conditions which can be affected by time and by changing these conditions. Therefore, social marketing framework should emphasize on the need for a comprehensive and proper understanding of consumers of each product and categorize them by their differences in planning and implementing social marketing programs. Thus one can be certain that intervention programs reach more appropriate consumers and cause desired consumption behavior changes

At the detailed analyzing of regularities of heat treatment processes of fish in different modes a significant amount of experienced material was successfully generalized on the basis of dimensionless simplex (similarity numbers. Using the dimensionless simplex allowed to detect a number of simple mathematical models for the studied phenomena. The generalized kinetic models of fish dehydration, the generalized dynamic models (changing moisture diffusion coefficients, the generalized kinetic models of fish heating (the temperature field changing in the products thickness, average volume and center were founded. These generalized mathematical models showed also relationship of dehydration and heating at the processes of fish semi-hot, hot smoking (drying and frying. The relationship of the results from the physical nature of the dehydration process, including a change in the binding energy of the moisture with the material to the extent of the process and the shrinkage impact on the rate of the product moisture removal is given in the article. The factors influencing the internal structure and properties of the raw material changing and retarding the dehydration processes are described there. There was a heating rate dependence of fish products on the chemical composition the geometric dimensions of the object of heating and on the coolant regime parameters. A unique opportunity is opened by using the generalized models, combined with empirically derived equations and the technique of engineering calculation of these processes, to design a rational modes of heat treatment of raw materials and to optimize the performance of thermal equipment.

  8. Critical reflexivity in financial markets: a Hawkes process analysis

    2013-10-01

    We model the arrival of mid-price changes in the E-mini S&P futures contract as a self-exciting Hawkes process. Using several estimation methods, we find that the Hawkes kernel is power-law with a decay exponent close to -1.15 at short times, less than ≈ 103 s, and crosses over to a second power-law regime with a larger decay exponent ≈-1.45 for longer times scales in the range [ 103,106 ] seconds. More importantly, we find that the Hawkes kernel integrates to unity independently of the analysed period, from 1998 to 2011. This suggests that markets are and have always been close to criticality, challenging a recent study which indicates that reflexivity (endogeneity) has increased in recent years as a result of increased automation of trading. However, we note that the scale over which market events are correlated has decreased steadily over time with the emergence of higher frequency trading.

    The use of phosphate additives in meat and fish processing leads to a phosphorus overload that we cannot quantify through labelling or food composition tables. We analysed this increase by measuring phosphorus content in these products by spectrophotometry. We determined the phosphorus/protein ratio in fresh meat and fish products with varying degrees of processing by spectrophotometry (phosphorus) and the Kjeldahl method (proteins). We contrasted these results with those reflected in the food composition tables. The phosphorus/protein ratio was higher in processed meat products (15.83 mg/g) than in battered (11.04 mg/g) and frozen meat products (10.5mg/g), and was lower in fresh (8.41 mg/g) and refrigerated meat products (8.78 mg/g). Fresh white fish had a phosphorus/protein ratio of 8.58mg/g, while it increased by 22% (10.3mg/g) in frozen white fish and by 46% (12.54 mg/g) in battered fish. The information in the tables was poor and confusing, and no reference is made to the brands tested. Processing meat and fish products poses a serious obstacle to the reduction of phosphorus intake. The current regulatory framework does not assist us in the objective of reducing phosphorus additives, since it considers them safe for public consumption. Overcoming these barriers requires a coordinated effort to demonstrate that a high intake of these additives may be harmful to the general population and it should be more closely examined by regulators.

    2009-01-01

    Full Text Available There are numerous parameters that can influence bacterial decontamination during washing of machinery and equipment in a food processing establishment. Incomplete decontamination of bacteria will increase the risk of biofilm formation and consequently increase the risk of pathogen contamination or prevalence of other undesirable microorganisms such as spoilage bacteria in the processing line. The efficiency of a typical washing protocol has been determined by testing three critical parameters and their effects on bacterial decontamination. Two surface materials (plastic and stainless steel, water temperatures (7 and 25 °C and detergent concentrations (2 and 4 % were used for this purpose in combination with two types of detergents. Biofilm was prepared on the surfaces with undefined bacterial flora obtained from minced cod fillets. The bacterial flora of the biofilm was characterised by cultivation and molecular analysis of 16S rRNA genes. All different combinations of washing protocols tested were able to remove more than 99.9 % of the bacteria in the biofilm and reduce the cell number from 7 to 0 or 2 log units of bacteria/cm2. The results show that it is possible to use less diluted detergents than recommended with comparable success, and it is easier to clean surface material made of stainless steel compared to polyethylene plastic.

  4. The liberalisation of the European electricity market : an unstructured restructuring process?

    International Nuclear Information System (INIS)

    Boisseleau, F.; Hakvoort, R.

    2005-01-01

    The European Union (EU) directive 96/92/EC defines common rules for the generation, transmission and distribution of electricity, paving the way for the liberalization of the electricity markets of EU member states. Member states are obliged to open their national electricity supply markets, meaning that eligible customers can choose their own suppliers. This paper discussed the process by which the countries of the EU have restructured their electricity markets, arguing that the process has focused on legal and organizational issues, rather than specific prescriptions for the economic design of the market. Although the objective of the EU directive was to create a competitive market, restructuring has led to 15 or more fragmented markets, each liberalized to a different degree and shaped following a wide range of different principles. Areas where the EU has failed to provide a coherent market view were discussed. Issues concerning short-term market arrangements, congestion management and long-term investment were examined. Section 1 of the paper focused on policy issues in the liberalization process, while section 2 emphasized the importance of market design. Section 3 addressed the need for market monitoring and the issue of market power. It was concluded that liberalization is only one step in the process that alone cannot deliver the expected benefits of single integrated European-wide market. At present, the European electricity market is hindered by a lack of proper design and sufficient transparency. 32 refs., 3 tabs., 4 figs

    Mo, Wing Yin; Man, Yu Bon; Wong, Ming Hung

    2018-02-01

    China's aquaculture industry is growing dramatically in recent years and now accounts for 60.5% of global aquaculture production. Fish protein is expected to play an important role in China's food security. Formulated feed has become the main diet of farmed fish. The species farmed have been diversified, and a large amount of 'trash fish' is directly used as feed or is processed into fishmeal for fish feed. The use of locally available food waste as an alternative protein source for producing fish feed has been suggested as a means of tackling the problem of sourcing safe and sustainable feed. This paper reviews the feasibility of using locally available waste materials, including fish waste, okara and food waste. Although the fishmeal derived from fish waste, okara or food waste is less nutritious than fishmeal from whole fish or soybean meal, most fish species farmed in China, such as tilapia and various Chinese carp, grow well on diets with minimal amounts of fishmeal and 40% digestible carbohydrate. It can be concluded that food waste is suitable as a component of the diet of farmed fish. However, it will be necessary to revise regulations on feed and feed ingredients to facilitate the use of food waste in the manufacture of fish feed. Copyright © 2017 Elsevier B.V.

    Kinetic aspects of the development of lipid oxidation in complex foods as fish in the course of irradiation were analyzed with respect to the associated formation of malonaldehyde (MA) through the reactions modified so as to be consistent with those in complex foods as fish. Air-packed anchovy (Engraulis encrasicholus) samples in polyethylene pouches were irradiated at the doses of 1, 2, 5, 10, 15,20 and 25 kGy at 20 o C in a Cs-137 gamma irradiator of 1.806 kGy/h dose rate. Immediately after each irradiation, MA contents of irradiated and unirradiated samples were determined by thiobarbituric acid test. Based on the MA formation, a kinetic model to simulate the apparent oxidation of lipid in fish as a function of irradiation dose was derived from the rate equations consistent with modified reactions. Kinetic parameters and simulation were related to conditions of lipid oxidation, and associated rancidity state of fish with respect to the doses applied in different irradiation-preservation processes. Numerical values of kinetic parameters based on the MA formation were found as a threshold dose of 0.375 kGy, an apparent yield of 1.871 μmol/kg kGy, and a maximum attainable concentration of 15.853 μmol/kg which may be used for process control and dosimetry.

    2018-05-01

    Full Text Available Segregation techniques represent a sustainable alternative to minimize wastes of raw material in processing industries. This study considered the premise; its purpose was to use segregation techniques to determine the theoretical removal rate of solid compounds present in processing effluents, in order to support the sustainable development of the fish industry. The removal rates obtained for different treatments were evaluated for the parameters: total solids, organic matter and oils and greases, and the efficiency of the segregation of the effluent streams in the different stages of fish processing was evaluated through descriptive statistical analysis. The segregation recovered from 31% to 70% of total solids; from 15% to 97.50% of organic matter, and from 10% to 63% of oils and greases. These results indicates that the raw material can be used in new products, leading to reduced final-effluent concentration.

  10. Priceless prices and marine food webs: Long-term patterns of change and fishing impacts in the South Brazil Bight as reflected by the seafood market

    2010-10-01

    The lack of market variables in fishery systems (i.e., prices and quantities) has often been cited as one reason for the particular difficulty of understanding whole marine ecosystem change and its management under a broader ecosystem perspective. This paper shows the results of efforts to tackle this problem in the South Brazil Bight by compiling and analyzing in-depth an unprecedented 40-year database from the region’s largest wholesale seafood market, based in the megacity of São Paulo. Fishery landings and market values for the period 1968-2007 were analyzed primarily by updated trophic level classes and multispecies indicators including the (1) marine trophic index (MTI), (2) weighted price, and (3) log relative price index (LRPI) which relates prices and trophic levels. Moreover, an inferential analysis of major seafood category statistical trends in market prices and quantities and their positive and negative correlations was undertaken. In general, these market trends contributed substantially to identifying and clarifying the changes that occurred. Considerations of the behavior of demand, supply and markets are included. In particular, while the MTI did not support a “fishing down the marine food web” hypothesis, other indicators did show the continued scarcity of major high trophic level categories and fisheries target species. Overall, the results indicate that the analysis of fishery landings, or of certain other indicators alone, can mask real changes. Rather, a joint ecological-econometric analysis provides better evidence of the direction of ecosystem pressures and stock health. This method for detecting market changes across the food web may be particularly helpful for systems considered data-poor but where fish market data have been archived. This study further elucidates historical changes and fishing impacts in the South Brazil Bight ecosystem.

  11. Current problems of raw fish material processing while manufacturing dried products

    2017-09-01

    Full Text Available The substantiation for using techniques of fish raw material canning has been presented, raw fish being caught or farmed in aquaculture. The main problems in raw fish canning have been reviewed, including significant reduction in thermolabile vitamins in the ultimate product as compared with the raw material due to the thermal processing. Promising canning technique – vacuum drying – has been proposed. This technique makes possible to reduce the temperature of thermal processing down to 50…55 °С and significantly enlarge preservation of thermolabile vitamins from the raw fish. Sampling of raw materials, semi-finished products, finished products, including preparation for analysis has been conducted by standard methods. Disadvantages of this way have been found, it is low energy efficiency of the process. The way to intensify the vacuum drying of aquatic organisms has been proposed based on the method of preliminary pore-forming due to augmenting the area of moisture evaporation. The design of the pilot plant has been proposed in order to research the process of pore forming and vacuum drying. Target species for processing have been suggested. They are as follows: Azov goby (fillet for food products and Black Sea sprat for feeds. The recipes of the feed mixture for granulated floating food for trout have been developed. The results of the first series of the pilot research have been provided. The experiments have proved that preliminary pore forming immediately before vacuum drying makes possible to enlarge the surface area of moisture evaporation by 15…25 %. By processing photomicrographs of sections by means of a special software the authors have got the results demonstrating that when manufacturing dried products by pore forming and drying under pressure 10 kPa the pore take 35...38 % of the inner volume of the product and with drying under pressure 10 kPa – only 18...21 %, and when drying under the atmospheric pressure – 11...13 %.

  12. KINETICS PROCESSES OF DEHYDRATION AND HEATING FISH DURING FRYING, DURING SEMI HOT AND HOT SMOKING

    Directory of Open Access Journals (Sweden)

    V. A. Pokholchenko

    2014-01-01

    Full Text Available Summary. Calculated methods of graphing of curves for kinetics of dehydration and fish heating during the processes of frying, semi hot smoking and hot smoking have been developed. The offered methods of calculating are based on the basic regularities of heat and mass exchanges of these processes. Based on the research of the regularities of dehydration on the kinetic curves, critical points were identified, that characterize the transition from the moisture removal with lower energy of its bond with material to the removal of one with higher energy bond, also the influence of the product shrinkage on the velocity of the moisture removal. These points are characteristic for the temperature curves as well. It’s suggested for the temperature curve to be replaced by broken line that consists of three straight lines that are crossing in points, corresponded with the critical moistures and critical temperatures. Significant amount of the experimental material of the research of the kinetics of dehydration and fish heating under different modes is shown by authors in the form of generalized dependencies. The method allows modeling the processes of heating and dehydrating of fish and choosing the most rational modes based on the calculated data. The proposed technique makes it possible to construct the curves of the kinetics of heating and dehydration kinetics in processes of roasting, semi hot and hot smoked fish, which allows to optimize a particular process, design more efficient in terms of consumption of raw materials and energy technology, as well as to create better machines or upgrade existing equipment into account the relationship of heat and mass transfer processes.

    Shanghai is a Chinese megacity in the Yangtze River Delta area, one of the most polluted coastal areas in China. The inhabitants of Shanghai have very high aquatic product consumption rates. A risk–benefit assessment of the co-ingestion of fish nutrients and contaminants has not previously been performed for Shanghai residents. Samples of five farmed fish species (marine and freshwater) with different feeding habits were collected from Shanghai markets in winter and summer. Fatty acids, protein, mercury, cadmium, lead, copper, polychlorinated biphenyls, hexachlorocyclohexanes, and dichlorodiphenyltrichloroethanes were measured in liver, abdominal fat, and dorsal, abdominal, and tail muscles from fish. Tolerable daily intakes and benefit–risk quotients were calculated to allow the benefits and risks of co-ingesting n − 3 long-chain polyunsaturated fatty acids and contaminants to be assessed according to the cancer slope factors and reference doses of selected pollutants. All of the contaminant concentrations in the muscle tissues were much lower than the national maximum limits, but the livers generally contained high Hg concentrations, exceeding the regulatory limit. The organic pollutant and n − 3 long-chain polyunsaturated fatty acid concentrations correlated with the lipid contents of the fish tissues, and were higher in carnivorous marine fish than in omnivorous and herbivorous freshwater fish. The tolerable daily intakes, risk–benefit quotients, and current daily aquatic product intakes for residents of large Chinese cities indicated that the muscle tissues of most of the fish analyzed can be consumed regularly without significant contaminant-related risks to health. However, attention should be paid to the potential risks posed by dichlorodiphenyltrichloroethane in large yellow croaker and Hg in tilapia. Based on the results of this study, we encourage people to consume equal portions of marine and freshwater fish. - Highlights: • Shanghai coast

  17. Fish gelatin.

    2010-01-01

    Gelatin is a multifunctional ingredient used in foods, pharmaceuticals, cosmetics, and photographic films as a gelling agent, stabilizer, thickener, emulsifier, and film former. As a thermoreversible hydrocolloid with a narrower gap between its melting and gelling temperatures, both of which are below human body temperature, gelatin provides unique advantages over carbohydrate-based gelling agents. Gelatin is mostly produced from pig skin, and cattle hides and bones. Some alternative raw materials have recently gained attention from both researchers and the industry not just because they overcome religious concerns shared by Jews and Muslims but also because they provide, in some cases, technological advantages over mammalian gelatins. Fish skins from a number of fish species are among the other sources that have been comprehensively studied as sources for gelatin production. Fish skins have a significant potential for the production of high-quality gelatin with different melting and gelling temperatures over a much wider range than mammalian gelatins, yet still have a sufficiently high gel strength and viscosity. Gelatin quality is industrially determined by gel strength, viscosity, melting or gelling temperatures, the water content, and microbiological safety. For gelatin manufacturers, yield from a particular raw material is also important. Recent experimental studies have shown that these quality parameters vary greatly depending on the biochemical characteristics of the raw materials, the manufacturing processes applied, and the experimental settings used for quality control tests. In this review, the gelatin quality achieved from different fish species is reviewed along with the experimental procedures used to determine gelatin quality. In addition, the chemical structure of collagen and gelatin, the collagen-gelatin conversion, the gelation process, and the gelatin market are discussed. Copyright © 2010 Elsevier Inc.

    Garcia, Gabriel Macasiray; de Castro, Butch

    2017-05-01

    This study explored how unique environmental conditions in Alaska influenced occupational health and safety for Filipino fish processing workers, many of whom migrated from warm locations (e.g., the Philippines, California, and Nevada). In-depth interviews were conducted with 26 Filipino workers in one commercial fish processing company in Dutch Harbor. Results indicated that cold weather interferes with workers' job performance, increasing their risk for injury and illness, whereas the community's isolation and rural nature causes loneliness and boredom, resulting in more high-risk behaviors. Other non-environmental factors affecting worker health include roommate and supervisor concerns and culture-specific practices. Findings suggest the importance of job rotation to avoid long exposures to cold temperatures, the value of a designated individual to inform workers about company and community resources that promote healthy lifestyles, and the possible utility of a joint worker-management safety committee.

    The aim of this study was to determine the level of heavy metals and polycyclic aromatic hydrocarbons (PAHs) in 57 samples of canned tuna, 25 samples of canned sardines, and 16 samples of canned smoked sprouts, collected from supermarkets in Serbia. Heavy metal levels (lead, cadmium, mercury, arsenic, iron, copper, and zinc) were determined using an inductive coupled plasma mass spectrometry method. Sixteen analysed PAHs were determined using a gas chromatography-mass spectrometry method. The trace elements in canned fish were in the range (mg kg -1 ) of 0.01-0.28 for lead, 0.003-0.08 for cadmium, 0.007-0.64 for mercury, 0.17-3.73 for arsenic, 3.88-52.2 for iron, 0.2-5.95 for copper, and 1.35-44.5 for zinc. Total PAH levels reached 17.67 µg kg -1 in canned tuna and 15.12 µg kg -1 in sardines, whereas in smoked sprouts it amounted to 57.19 µg kg -1 . Some of the samples contained cadmium, arsenic, copper, and benzo(a)pyrene above the limits as set by the European and Serbian legislation.

    Developing the promotional strategy is often the most exciting and enjoyable part of the social marketing plan. Health communication and social marketing campaigns that combine mass media with the distribution of health-related products, such as child safety restraints and sun protection products, have shown strong evidence of effectiveness for producing intended behavior changes (Guide to Community Preventive Services, 2010). This article discusses the promotional aspect of social marketing plans--the fourth P in the marketing mix that includes product, place, and price--and how public health practitioners can work with creative professionals to be sure that the creative development and execution of promotional messages and materials stay "on strategy" and support their objectives.

    The analysis of aflatoxins (B1, B2, G1 and G2) and ochratoxin A (OTA) was performed in processed spices marketed in Penang, Malaysia, using immunoaffinity columns and HPLC equipped with fluorescence detector (HPLC-FD). The processed powdered spices analysed include dried chilli, fennel, cumin, turmeric, black and white pepper, poppy seed, coriander, 'garam masala', and mixed spices for fish, meat and chicken curry. Two different studies were carried out. The limit of detection (LOD) was 0.01 ng g(-1) for each aflatoxin (AF) and 0.10 ng g(-1) for OTA (signal-to-noise ratio = 3:1). In the first study, 34 commercial processed spices analysed with a mean level, range and incidence of positive samples for total AF were 1.61 ng g(-1), 0.01-9.34 ng g(-1) and 85%, respectively, and for AFB1 were 1.38 ng g(-1), 0.01-7.68 ng g(-1) and 85%, respectively. The mean level, range and incidence of positive samples for OTA were 2.21 ng g(-1), 0.14-20.40 ng g(-1) and 79%, respectively. Natural co-occurrence of AF and OTA was found in 25 (74%) samples. In the second study of 24 commercial processed spices, the mean level, range and incidence of positive samples for total AF were 8.38 ng g(-1), 0.32-31.17 ng g(-1) and 88%, respectively, and for AFB1 were 7.31 ng g(-1), 0.32-28.43 ng g(-1) and 83%, respectively. Fifteen positive samples for total AF and two positive samples for OTA exceeded the permissible Malaysian limit of 5 ng g(-1). Contamination of both mycotoxins in spices may represent another route of exposure to consumers due to their frequent and prolonged consumption, as spices are common ingredients in popular dishes among Asian countries.

  2. PRICE GENERATING PROCESS AND VOLATILITY IN NIGERIAN AGRICULTURAL COMMODITIES MARKET

    Full Text Available The literature on agricultural commodity price volatility in Nigeria has constantly reflected that an excessive price movement is harmful for both producers and consumers, particularly for those who are not able to cope with that new source of economic uncertainty. It has also raised an extensive debate on the main determinants behind the large agricultural commodity price swings observed in the last years without recourse for the price generating process. To narrow this gap, the study examined the price generating process and volatility in the Nigerian agricultural commodities market using secondary data for price series on meat, cereals, sugar, dairy and aggregate food for the period of January 1990 to February 2014. The data were analysed using the linear Gaussian State-Space (SS model. The results of the descriptive statistics showed that the coefficients of variation for cereals (39.88%, food (32.65% and dairy price (43.08% were respectively higher during the overall time period (January 1990 to February 2014 than during the first (January 1990 to January 2002 and second (February 2002 to February 2014 sub-time periods. The results of the inferential statistics showed that authoregressive moving average (ARMA model is the most selected Nigeria agricultural commodity price generating model for the time periods, that a unit increase in the past price state of cereals, dairy, sugar, meat and aggregate food would increase the future price of sugar, meat and aggregate food by N0.14, N0.28 and N0.15 respectively but decrease future price of cereals and dairy by about N1.00 and N0.21 respectively, and that the one-step ahead predicted value for the first out-ofsample period for cereals, meat, dairy and sugar price were 6317.86, 10.24 and 2.06 respectively. The Nigerian agricultural commodity prices have experienced high variability over the period, and such volatility, price-generating process and the determinants of the Nigerian food commodities

  5. Supervised pre-processing approaches in multiple class variables classification for fish recruitment forecasting

    KAUST Repository

    Fernandes, José Antonio

    2013-02-01

    A multi-species approach to fisheries management requires taking into account the interactions between species in order to improve recruitment forecasting of the fish species. Recent advances in Bayesian networks direct the learning of models with several interrelated variables to be forecasted simultaneously. These models are known as multi-dimensional Bayesian network classifiers (MDBNs). Pre-processing steps are critical for the posterior learning of the model in these kinds of domains. Therefore, in the present study, a set of \\'state-of-the-art\\' uni-dimensional pre-processing methods, within the categories of missing data imputation, feature discretization and feature subset selection, are adapted to be used with MDBNs. A framework that includes the proposed multi-dimensional supervised pre-processing methods, coupled with a MDBN classifier, is tested with synthetic datasets and the real domain of fish recruitment forecasting. The correctly forecasting of three fish species (anchovy, sardine and hake) simultaneously is doubled (from 17.3% to 29.5%) using the multi-dimensional approach in comparison to mono-species models. The probability assessments also show high improvement reducing the average error (estimated by means of Brier score) from 0.35 to 0.27. Finally, these differences are superior to the forecasting of species by pairs. © 2012 Elsevier Ltd.

  6. Biophysical processes leading to the ingress of temperate fish larvae into estuarine nursery areas: A review

    Teodósio, Maria Alexandra; Paris, Claire B.; Wolanski, Eric; Morais, Pedro

    2016-12-01

    A series of complementary hypotheses have been proposed to explain the recruitment of marine and temperate pelagic fish larvae originated from pelagic eggs in coastal environments. In this review, we propose a new and complementary hypothesis describing the biophysical processes intervening in the recruitment of temperate fish larvae into estuaries. This new hypothesis, the Sense Acuity And Behavioral (SAAB) hypothesis, recognizes that recruitment is unlikely if the larvae drift passively with the water currents, and that successful recruitment requires the sense acuity of temperate fish larvae and their behavioral response to the estuarine cues present in coastal areas. We propose that temperate fish larvae use a hierarchy of sensory cues (odor, sound, visual and geomagnetic cues) to detect estuarine nursery areas and to aid during navigation towards these areas. The sensorial acuity increases along ontogeny, which coincides with increased swimming capabilities. The swimming strategies of post-flexion larvae differ from offshore areas to the tidal zone. In offshore areas, innate behavior might lead larvae towards the coast guided by a sun compass or by the earth's geomagnetic field. In areas under limited influence of estuarine plumes (either in energetic nearshore areas or offshore), post-flexion larvae display a searching swimming behavior for estuarine disconnected patches (infotaxis strategy). After finding an estuarine plume, larvae may swim along the increasing cue concentration to ingress into the estuary. Here, larvae exhibit a rheotaxis behavior and avoid displacement by longshore currents by keeping bearing during navigation. When larvae reach the vicinity of an estuary, merging diel rhythms with feeding and predator avoidance strategies with tidally induced movements is essential to increase their chances of estuarine ingress. A fish larva recruitment model developed for the Ria Formosa lagoon supports the general framework of the SAAB hypothesis. In

    India is bestowed with vast livestock wealth and it is growing at the rate of 6% per annum. The contribution of livestock industry including poultry and fish is increasing substantially in GDP of country which accounts for >40% of total agricultural sector and >12% of GDP. This contribution would have been much greater had the animal by-products been also efficiently utilized. Efficient utilization of by-products has direct impact on the economy and environmental pollution of the country. Non-utilization or under utilization of by-products not only lead to loss of potential revenues but also lead to the added and increasing cost of disposal of these products. Non-utilization of animal by-products in a proper way may create major aesthetic and catastrophic health problems. Besides pollution and hazard aspects, in many cases meat, poultry and fish processing wastes have a potential for recycling raw materials or for conversion into useful products of higher value. Traditions, culture and religion are often important when a meat by-product is being utilized for food. Regulatory requirements are also important because many countries restrict the use of meat by-products for reasons of food safety and quality. By-products such as blood, liver, lung, kidney, brains, spleen and tripe has good nutritive value. Medicinal and pharmaceutical uses of by-product are also highlighted in this review. Waste products from the poultry processing and egg production industries must be efficiently dealt with as the growth of these industries depends largely on waste management. Treated fish waste has found many applications among with which the most important are animal feed, biodiesel/biogas, dietectic products (chitosan), natural pigments (after extraction) and cosmetics (collagen). Available information pertaining to the utilization of by-products and waste materials from meat, poultry and fish and their processing industries has been reviewed here.

    Full Text Available We are looking for the answer as to what tendencies were indicative of the future development of required marketing activity of the SMEs in the article dealing with the marketing activity of the SMEs working in the food industry. The article is based on a nationwide survey among 200 SMEs working in the food processing industry. In this article, we focus on the SMEs working in the dairy and meat processing industries. The results of the nationwide research and some domestic references refer to that there is a latent demand of effective marketing activity among small and medium-sized enterprises. It manifests itself in specifying marketing-related fields to be improved in the future. The marketing itself is believed not to be an important field at the same time. This apparent opposition is the small enterprise marketing paradox in the background of which is the lack of knowledge about the marketing instruments. It can be stated that these small businesses collect mainly general market information and have no information about particular products. Therefore, the presence of marketing planning is really rare and where there is some kind of planning it is not connected to available funds and follow-up control. The marketing strategy can be characterized by products processed mainly at low or medium level. Therefore, market position is deffned by “lower price-good quality”. They mainly use the traditional distribution channels and their communication is accidental and has a low level.

    Full Text Available Five diets were prepared using fish processing waste meal (FMFP to replace fish meal (FM at inclusion levels of 0, 25, 50, 75 and 100%. Frog diet was used as a control diet. Nile tilapia (Oreochromis niloticus were reared in laboratory conditions for 8 weeks. It was found that substitution levels of protein from FMFP in the tested diets reduced growth and feed efficiency of tilapia (p<0.05. However, the differences looks like significant trend especially that between the 100% substitution level and the frog diet. Substitution of FM by FMFD at 75% reduced cost of feed by 15.35%. It was concluded that up to 75% inclusion of FMFD in the diet of tilapia could support normal growth of Nile tilapia with the potential for substitution of FM.

    2013-01-01

    Full Text Available In this research, three variance ratio tests: the standard variance ratio test, the wild bootstrap multiple variance ratio test, and the non-parametric rank scores test are adopted to test the random walk hypothesis (RWH of stock markets in Middle East and North Africa (MENA region using most recent data from January 2010 to September 2012. The empirical results obtained by all three econometric tests show that the RWH is strongly rejected for Kuwait, Tunisia, and Morocco. However, the standard variance ratio test and the wild bootstrap multiple variance ratio test reject the null hypothesis of random walk in Jordan and KSA, while non-parametric rank scores test do not. We may conclude that Jordan and KSA stock market are weak efficient. In sum, the empirical results suggest that return series in Kuwait, Tunisia, and Morocco are predictable. In other words, predictable patterns that can be exploited in these markets still exit. Therefore, investors may make profits in such less efficient markets.

  17. Fish invasions in the world's river systems: when natural processes are blurred by human activities.

    Directory of Open Access Journals (Sweden)

    Fabien Leprieur

    2008-02-01

    Full Text Available Because species invasions are a principal driver of the human-induced biodiversity crisis, the identification of the major determinants of global invasions is a prerequisite for adopting sound conservation policies. Three major hypotheses, which are not necessarily mutually exclusive, have been proposed to explain the establishment of non-native species: the "human activity" hypothesis, which argues that human activities facilitate the establishment of non-native species by disturbing natural landscapes and by increasing propagule pressure; the "biotic resistance" hypothesis, predicting that species-rich communities will readily impede the establishment of non-native species; and the "biotic acceptance" hypothesis, predicting that environmentally suitable habitats for native species are also suitable for non-native species. We tested these hypotheses and report here a global map of fish invasions (i.e., the number of non-native fish species established per river basin using an original worldwide dataset of freshwater fish occurrences, environmental variables, and human activity indicators for 1,055 river basins covering more than 80% of Earth's surface. First, we identified six major invasion hotspots where non-native species represent more than a quarter of the total number of species. According to the World Conservation Union, these areas are also characterised by the highest proportion of threatened fish species. Second, we show that the human activity indicators account for most of the global variation in non-native species richness, which is highly consistent with the "human activity" hypothesis. In contrast, our results do not provide support for either the "biotic acceptance" or the "biotic resistance" hypothesis. We show that the biogeography of fish invasions matches the geography of human impact at the global scale, which means that natural processes are blurred by human activities in driving fish invasions in the world's river systems

  18. Rapid Fishery Assessment by Market Survey (RFAMS--an improved rapid-assessment approach to characterising fish landings in developing countries.

    Directory of Open Access Journals (Sweden)

    William T White

    Full Text Available The complex multi-gear, multi-species tropical fisheries in developing countries are poorly understood and characterising the landings from these fisheries is often impossible using conventional approaches. A rapid assessment method for characterising landings at fish markets, using an index of abundance and estimated weight within taxonomic groups, is described. This approach was developed for contexts where there are no detailed data collection protocols, and where consistent data collection across a wide range of fisheries types and geographic areas is required, regardless of the size of the site and scale of the landings. This methodology, which was demonstrated at seven fish landing sites/fish markets in southern Indonesia between July 2008 and January 2011, provides a rapid assessment of the abundance and diversity in the wild catch over a wide variety of taxonomic groups. The approach has wider application for species-rich fisheries in developing countries where there is an urgent need for better data collection protocols, monitoring future changes in market demographics, and evaluating health of fisheries.

    The aim of this research was to investigate the occurrence of Listeria monocytogenes in fish and fish processing plant and to determine their transmission, virulence and antibiotic resistance. L. monocytogenes was isolated according to the ISO 11290-1. The identification of L. monocytogenes was confirmed by multiplex PCR method. Genetic similarity of L. monocytogenes strains was determined with the Pulsed-Filed Gene Electrophoresis (PFGE) method. The multiplex PCR was used for identification of L. monocytogenes serogroups and detection of selected virulence genes (actA, fbpA, hlyA, iap, inlA, inlB, mpl, plcA, plcB, prfA). The L. monocytogens isolates susceptibility to penicillin, ampicillin, meropenem, erythromycin, trimethoprim/sulfamethoxazole was evaluated with disc diffusion method according to EUCAST v. 7.1. The presence of 237 L. monocytogenes isolates (before genetic similarity assessment) in 614 examined samples was confirmed. After strain differentiation by PFGE techniques the presence of 161 genetically different strains were confirmed. The genetic similarity of the examined isolates suggested that the source of the L. monocytogenes strains were fishes originating from farms. All tested strains possessed all detected virulence genes. Among examined strains, the most (26, 38.6%) belonged to the group 1/2a-3a. The most of tested strains were resistant to erythromycin (47.1%) and trimethoprim/sulfamethoxazole (47.1%). Copyright © 2018. Published by Elsevier B.V.

  1. Evaluation of coastal waters receiving fish processing waste: Lota Bay as a case study.

    Liquid wastes from the fish meal and oil processing industries produce serious environmental impacts in coastal embayments on the coasts of Chile and Peru. This article presents an analysis of an environmental monitoring program at Lota Bay, a shallow coastal indentation in central Chile (37 degrees S) exposed to industrial fishing activity. The study of the environmental impact produced by waste effluents permitted making an evaluation of the bay's capacity for seasonal recovery from this impact. Seasonal cruises were carried out during 1994 and in 1996, 1997, and 1998. Variables analyzed included salinity, temperature, dissolved oxygen, ammonium concentration and surface oil and grease. The hydrographic regime of Lota Bay follows a seasonal pattern, where, typical of most SE pacific embayments, waters from subsuperficial oxygen minimum zones moved into the bay. The percentages of dissolved oxygen were critical in the area of organic waste discharge. The impact of wastewater is related to the type and status of the fishery, including: (i) overloads of plant production lines, (ii) maintenance and cleaning of installations, and (iii) degree of shipboard fishing conservation. Major alterations were observed in summer, when the highest discharge of organic load occurred. In winter, an improvement in the re-aeration conditions reduced the impact. Remedial measures implemented beginning in 1997 arose from the monitoring program and had to be separated into two recovery factors including (a) internal management of plants and (b) treatment of plant effluents.

    1997-01-01

    Kinetic studies on radiation-inactivation and the postirradiation growth of spoilage microorganisms during chill storage and their product formation inradurized fish were carried out. Anchovy (Engraulis encrasicholus) samples unirradiated, and those irradiated at 1,2 and 3 kGy doses of gamma radiation were stored at +2 o C for 21 days. Microbiological analyses of mesophilic, psycrophilic and total bacterial counts (TBC) and chemical analyses of trimethylamine (TMA) and total volatile bases (TVB) of the samples were done immediately after irradiation and periodically during storage. Radiation induced inactivations of bacteria were expressed with a first-order decreasing kinetics. A spoilage fermentation modeling was used to evaluate the quality control parameters of radurized fish in which the increase in TBC of survivor microorganisms during storage was described by a first-order growth with a lag phase and the production of TMA and TVB was described by a growth associated product formation. Examinations of the dose effects on the kinetic parameters resulted in that the relation between the product formation rate constants and the irradiation dose represented a parabolic function which was satisfactorily used to determine optimum irradiation dose. Optimum irradiation dose was found 1.719+- 0.471 kGy with TVB data resulting in an extended shelf-life of 15-16 days of fish. It is suggested that the kinetic evaluation method developed in this study may be substitute for or used with the analytical estimate in use comprising microbiological chemical and organoleptic controls for quality assessment and dose optimization of radurization processing of fish and other sea foods.(2 tab s. and 24 refs.)

    2008-09-01

    Full Text Available The profile of sardine fishing, the Triportheus species, landed at the fishing market of Porto Velho (RO between 1990 and 2004, was established by analyzing variations in the intra- and inter-annual yield as well as the length and general characteristics of the fishing. The annual production varied from 15,372 to 78,340kg (average = 33,482kg, totaling 5.46% of the overall production during the studied period. These variations can be related to the changes in the fishermen’s effort, as a reflex to searching for alternatives for fishing, or related to the level of the river, since the greatest annual yields were preceded by years of having more intense flooding. The monthly production varied from 0 to 21,456kg (average=2,876kg. Greater values of production were obtained in periods of lower hydrological levels (dry season [r(Pearson= -0.53. p<0.0001]. The average capture per fisherman/day between 2003 and 2004 was 9.27kg. Rivers were the main environment from which the captures took place, mainly from the Jamari, Machado and Novo Aripuanã rivers, that are tributaries of the Madeira River. The lengths of the fishes varied from 70 to 380mm and presented a bimodal pattern, suggesting the presence of more than one species within the captures.

    2014-04-01

    This study provides insight for food safety (FS) performance in light of the current performance of core FS management system (FSMS) activities and context riskiness of these systems to identify the opportunities for improvement of the FSMS. A FSMS diagnostic instrument was applied to assess the performance levels of FSMS activities regarding context riskiness and FS performance in 14 fish processing companies in Tanzania. Two clusters (cluster I and II) with average FSMS (level 2) operating under moderate-risk context (score 2) were identified. Overall, cluster I had better (score 3) FS performance than cluster II (score 2 to 3). However, a majority of the fish companies need further improvement of their FSMS and reduction of context riskiness to assure good FS performance. The FSMS activity levels could be improved through hygienic design of equipment and facilities, strict raw material control, proper follow-up of critical control point analysis, developing specific sanitation procedures and company-specific sampling design and measuring plans, independent validation of preventive measures, and establishing comprehensive documentation and record-keeping systems. The risk level of the context could be reduced through automation of production processes (such as filleting, packaging, and sanitation) to restrict people's interference, recruitment of permanent high-skilled technological staff, and setting requirements on product use (storage and distribution conditions) on customers. However, such intervention measures for improvement could be taken in phases, starting with less expensive ones (such as sanitation procedures) that can be implemented in the short term to more expensive interventions (setting up assurance activities) to be adopted in the long term. These measures are essential for fish processing companies to move toward FSMS that are more effective.

    Full Text Available Market process theory is designed by the followers of Austrian School tradition as an alternative to neo-classic price theory in order to explain perceptible markets. Contrary to neo-classic economy which focuses on the concept of equilibrium, market process theory seeks to explore unequilibrium and direction to equilibrium. While doing so, the role of enterprenuer in dealing with limited information which is not taken into consideration in the price theory of neo-classic economy, uncertainty because of time and uncertainty which occurs in market underpins Israel Kirzner's analyses. In the study, Kirzner's competition and enterpreneurship theory is discussed with the contributions of Mises and Hayek. The study constitutes an introduction to market process theory of Kirzner.

    American Electric Power Company, Inc., is exploring the feasibility of using a patented signal development process and sound system to guide aquatic animals with underwater sound. Sounds from animals such as chinook salmon, steelhead trout, striped bass, freshwater drum, largemouth bass, and gizzard shad can be used to synthesize a new signal to stimulate the animal in the most sensitive portion of its hearing range. AEP's field tests during its research demonstrate that adult chinook salmon, steelhead trout and warmwater fish, and steelhead trout and chinook salmon smolts can be repelled with a properly-tuned system. The signal development process and sound system is designed to be transportable and use animals at the site to incorporate site-specific factors known to affect underwater sound, e.g., bottom shape and type, water current, and temperature. This paper reports that, because the overall goal of this research was to determine the feasibility of using sound to divert fish, it was essential that the approach use a signal development process which could be customized to animals and site conditions at any hydropower plant site

    Full Text Available Abstract A cross sectional survey was initiated to understand the frequency of occupational injury occurrence and the associated factors in the fish processing industries of western India involving 185 randomly selected women subjects. All the subjects were interviewed with the help of an interviewer-administered questionnaire to collect information regarding their personal, occupational and work related morbidity details (including details of occupational injuries. Logistic regression method was used to analyze the data in order to obtain the contribution of individual factors on occupational injuries. This study has shown that work related morbidity like blanching of hand (OR; 2.30, 95%CI; 1.12–4.74 and nature of job like grading (OR; 3.99, 95%CI; 1.41–11.27 and packing (OR; 5.68, 95%CI; 1.65–19.57 had a significant impact on injury causation. This study eventually concludes that apart from nature of job of fish processing workers occupational hazards prevailing in the work environment contribute significantly to the occurrence of work related injuries and prevention of such occupational hazards may help in protecting workers from occupational injuries also.

    The renal diet must include limited amounts of high quality protein, phosphorus P and potassium K. n-3 polyunsaturated fatty acids (n-3PUFA EPA and DHA), present in fishes and mollusks, render beneficial properties against progression of renal damage. The aim of this study was to evaluate protein PR, phosphorus P, potassium K, calcium Ca and n-3PUFA in processed fishes and mollusks as an alimentary option for renal patients. Canned tuna (water AA and oil AC), sardine in tomate sauce ST and chipotle SC and smoked salmon SA, fresh jumbo flying squid CA, common octopus PU and oyster OS were evaluated. Significant difference was detected (p <.0.05) for K between different types of fish. SA contained 38g/100g PR, 307 mg/100g of P, 371 mg/ 100g K and 106 mg/100g n-3PUFA. Sardines contained (279-304 mg/100g of P and 283-322 mg/100g K and tunas 142-160 mg/100g P and 141-154 mg/100g K. Tunas and sardines had elevated concentration of n-3PUFA (4114 and 4790 mg/ 100g respectively), P:n-3PUFA and K:n-3PUFA ratio was low in tunas (0.03) and sardines (0.06). AA and AC contained (10.1 and 11.1 mgP/gPR), while ST and SC provided 26.4-19.1 mg/P/gPR. n-3PUFA/gPR were similar for tunas and sardines (302-424mg/gPR). Mollusks: CA presented the highest values of P and PR (2.4 mg/100g and 18.4g/100g). n-3PUFA ranged from 4.3 to 79 mg/100g in PU and OS respectively. Among processed fishes, only canned tunas are recommended for the diet of renal patients, in an individualized basis. The risk-benefit ratio of sardines in the renal diet should be evaluated, due to their high content of P and n-3PUFA. Salmon and mollusks are not recommended for the renal diet.

    Attracted by their high economic growth rates, young and growing populations, and increasingly open markets, transnational food and beverage corporations (TFBCs) are targeting Asian markets with vigour. Simultaneously the consumption of ultra-processed foods high in fat, salt and glycaemic load is increasing in the region. Evidence demonstrates that TFBCs can leverage their market power to shape food systems in ways that alter the availability, price, nutritional quality, desirability and ultimately consumption of such foods. This paper describes recent changes in Asian food systems driven by TFBCs in the retail, manufacturing and food service sectors and considers the implications for population nutrition. Market data for each sector was sourced from Euromonitor International for four lower-middle income, three upper-middle income and five high-income Asian countries. Descriptive statistics were used to describe trends in ultra-processed food consumption (2000-2013), packaged food retail distribution channels (1999-2013), 'market transnationalization' defined as the market share held by TFBCs relative to domestic firms (2004-2013), and 'market concentration' defined as the market share and thus market power held by the four leading firms (2004-2013) in each market. Ultra-processed food sales has increased rapidly in most middle-income countries. Carbonated soft drinks was the leading product category, in which Coca-Cola and PepsiCo had a regional oligopoly. Supermarkets, hypermarkets and convenience stores were becoming increasingly dominant as distribution channels for packaged foods throughout the region. Market concentration was increasing in the grocery retail sector in all countries. Food service sales are increasing in all countries led by McDonalds and Yum! Brands. However, in all three sectors TFBCs face strong competition from Asian firms. Overall, the findings suggest that market forces are likely to be significant but variable drivers of Asia

    Full Text Available This paper proposes a model that wants to offer some pertinent answers about the process of assimilation and operationalization of the marketing concept in the practice of local organizations in Romania. Considering the reality of organizational practice in Romania, which revealed a lack of consistency in the approach of assimilation and operationalization of the marketing concept, the model tries to capture a range of factors that determine and explain this phenomenon. Reality shows that many Romanian organizations either do not perceive the need and importance of marketing in their activity or assimilate and develop a priori, actions carried out by transnational companies that do not meet the particular context of the Romanian market and / or of internal environment. The model attempts to capture the peculiarities of the process of assimilation and operationalization of the concept of marketing in local organizations and describe the characteristics of each identified organizational structures.

    Although Europe 'produces' excellent science, it has not been equally successful in translating scientific results into commercially successful companies in spite of European and national efforts invested in supporting the translation process. The Idea-to-Market process is highly complex due to the large number of actors and stakeholders. ITECH was launched to propose recommendations which would accelerate the Idea-to-Market process of health technologies leading to improvements in the competitiveness of the European health technology industry in the global markets. The project went through the following steps: defining the Idea-to-Market process model; collection and analysis of funding opportunities; identification of 12 gaps and barriers in the Idea-to-Market process; a detailed analysis of these supported by interviews; a prioritization process to select the most important issues; construction of roadmaps for the prioritized issues; and finally generating recommendations and associated action plans. Seven issues were classified as in need of actions. Three of these are part of the ongoing Medical Device Directive Reform (MDR), namely health technology assessment, post-market surveillance and regulatory process, and therefore not within the scope of ITECH. Recommendations were made for eHealth taxonomy; Education and training; Clinical trials and Adoption space and Human Factors Engineering (HFE).

    2017-01-01

    The Institute for Marine Research and Observation (IMRO) - Ministry of Marine Affairs and Fisheries Republic of Indonesia (MMAF) has developed a potential fishing zone (PFZ) forecast using satellite data, called Peta Prakiraan Daerah Penangkapan Ikan (PPDPI). Since 2005, IMRO disseminates everyday PPDPI maps for fisheries marine ports and 3 days average for national areas. The accuracy in determining the PFZ and processing time of maps depend much on the experience of the operators creating them. This paper presents our research in developing an automated processing system for PPDPI in order to increase the accuracy and shorten processing time. PFZ are identified by combining MODIS sea surface temperature (SST) and chlorophyll-a (CHL) data in order to detect the presence of upwelling, thermal fronts and biological productivity enhancement, where the integration of these phenomena generally representing the PFZ. The whole process involves data download, map geo-process as well as layout that are carried out automatically by Python and ArcPy. The results showed that the automated processing system could be used to reduce the operator’s dependence on determining PFZ and speed up processing time.

    The increasing consumption of shark products, along with the shark’s fishing vulnerabilities, has led to the decrease in certain shark populations. In this study we used a DNA barcoding method to identify the species of shark landings at fishing ports, shark fin products in retail stores, and shark fins detained by Taiwan customs. In total we identified 23, 24, and 14 species from 231 fishing landings, 316 fin products, and 113 detained shark fins, respectively. All the three sample sources were dominated by Prionace glauca, which accounted for more than 30% of the collected samples. Over 60% of the species identified in the fin products also appeared in the port landings, suggesting the domestic-dominance of shark fin products in Taiwan. However, international trade also contributes a certain proportion of the fin product markets, as four species identified from the shark fin products are not found in Taiwan’s waters, and some domestic-available species were also found in the customs-detained sample. In addition to the species identification, we also found geographical differentiation in the cox1 gene of the common thresher sharks (Alopias vulpinus), the pelagic thresher shark (A. pelagicus), the smooth hammerhead shark (Sphyrna zygaena), and the scalloped hammerhead shark (S. lewini). This result might allow fishing authorities to more effectively trace the origins as well as enforce the management and conservation of these sharks. PMID:26799827

    The present work presents a study of the biological treatment of fish processing wastewater at salt concentration of 55 g/L. Wastewater was treated by both continuous stirred-tank reactor (CSTR) and membrane bioreactor (MBR) during 50 and 100 days, respectively. These biological processes involved salt-tolerant bacteria from natural hypersaline environments at different organic loading rates (OLRs). The phylogenetic analysis of the corresponding excised DGGE bands has demonstrated that the taxonomic affiliation of the most dominant species includes Halomonadaceae and Flavobacteriaceae families of the Proteobacteria (Gamma-proteobacteria class) and the Bacteroidetes phyla, respectively. The results of MBR were better than those of CSTR in the removal of total organic carbon with efficiencies from 97.9% to 98.6%. Nevertheless, salinity with increasing OLR aggravates fouling that requires more cleaning for a membrane in MBR while leads to deterioration of sludge settleability and effluent quality in CSTR.

    2008-09-01

    The analysis of long memory processes in capital markets has been one of the topics in finance, since the existence of the market memory could implicate the rejection of an efficient market hypothesis. The study of these processes in finance is realized through Hurst exponent and the most classical method applied is R/S analysis. In this paper we will discuss the efficiency of this methodology as well as some of its more important modifications to detect the long memory. We also propose the application of a classical geometrical method with short modifications and we compare both approaches.

    Full Text Available Increase in fish fillet export in Indonesia has caused an increase in its waste such as bones, spines, skin and entrails of fish. Fish bones can be processed by demineralization to produce collagen, an important food additive. The effect of addition of 5% of collagen obtained from fresh water, brackish water and sea water fish bone on the fish protein miofibril of grouper was investigated in this research. Water sorption isotherm, Ca-ATPase activity, gel strength, water holding capacity, folding test and viscosity during dehydration process were evaluated. The results showed that collagens made from various fish bones have different Ca-ATPase activity. The reduction rate of Ca-ATPase activity were in accordance with the reduction of water sorbtion isotherm, gel forming ability, water holding capacity, viscosity and folding test during dehydration process.

    To analyse the Na content and labelling of processed and ultra-processed food products marketed in Brazil. Cross-sectional study. A large supermarket in Florianopolis, southern Brazil. Ingredient lists and Na information on nutrition labels of all processed and ultra-processed pre-prepared meals and prepared ingredients, used in lunch or dinner, available for sale in the supermarket. The study analysed 1416 products, distributed into seven groups and forty-one subgroups. Five products did not have Na information. Most products (58.8 %; 95 % CI 55.4, 62.2 %) had high Na content (>600 mg/100 g). In 78.0 % of the subgroups, variation in Na content was at least twofold between similar products with high and low Na levels, reaching 634-fold difference in the 'garnishes and others' subgroup. More than half of the products (52.0 %; 95 % CI 48.2, 55.6 %) had at least one Na-containing food additive. There was no relationship between the appearance of salt on the ingredients list (first to third position on the list) and a product's Na content (high, medium or low; P=0.08). Most food products had high Na content, with great variation between similar products, which presents new evidence for reformulation opportunities. There were inconsistencies in Na labelling, such as lack of nutritional information and incomplete ingredient descriptions. The position of salt on the ingredients list did not facilitate the identification of high-Na foods. We therefore recommend a reduction in Na in these products and a review of Brazilian legislation.

    There are numerous factors that can have an impact on the microbial ecology and quality of frozen Pangasius hypophthalmus fillets during processing in Vietnam. The presence of spoilage bacteria along the processing line can shorten the shelf-life of thawed frozen fish products. Therefore, the spoilage microbiota throughout the processing chain of two companies (BC: large scale factory, chlorine-based process, BW: large scale factory, water-based process and SC: small scale factory, chlorine-based process) was identified by culture-dependent techniques and 16S rRNA gene sequencing. The microbiological counts were observed to be insignificantly different (p>0.05) between BC and BW. Surprisingly, chlorine treated fillets from the SC line were revealed to have significantly higher microbial counts than potable water treated fillets at BW line. This was determined to be a result of temperature abuse during processing at SC, with temperatures even greater than 10 °C being recorded from skinning onwards. On the contrary, the microbiota related to spoilage for BC and BW lines was determined by 16S rRNA gene sequencing to be more diverse than that on the SC line. A total of 174 isolates, 20 genera and 38 species were identified along the processing chains. The genera Aeromonas, Acinetobacter, Lactococcus and Enterococcus were prevalent at various processing steps on all the processing lines evaluated. A diverse range of isolates belonging to the Enterobacteriaceae such as Providencia, Shigella, Klebsiella, Enterobacter and Wautersiella were isolated from fillets sampled on the SC line whereas Serratia was only observed on fillets sampled on the BC and BW lines. The results can be used to improve Good Manufacturing Practices for processed Pangasius fillets and to select effective measures to prolong the shelf-life of thawed Vietnamese Pangasius fillets products. © 2013.

    Full Text Available This article contributes to the understanding of marketing strategy process when it presents the organizational and human factors that support the processes of implementation, identified in a qualitative study conducted in the creative industry of video game development. The research, a case study applied to four video and computer game companies was based on the Sashittal and Jassawalla (2001 marketing strategic model, and on the concepts of the creative behavior and innovation in organizations proposed by Amabile (1997. The analysis suggests that the marketing strategy implementation is anchored in innovative administrative process, creative skills and the adoption of modern control technologies. It was observed that a vision that associates production, process, the market orientation and the delivery of value-adding is essential for the implementation of strategies in creative and innovative organizational structures. The research contributes to the marketing strategy implementation studies in creative and innovative environments under the approach of smaller organizations. It also contributes with the marketing strategy theory when it suggests that the analysis of the process, the control and the management skills be included as categories into the theoretical model in future investigations.

    While the literature on price discovery process and information flow between dominant and satellite market is exhaustive, most studies have applied an approach that can be traced back to Hasbrouck (1995) or Gonzalo and Granger (1995). In this paper, however, we propose a Generalized Langevin process with asymmetric double-well potential function, with co-integrated time series and interconnected diffusion processes to model the information flow and price discovery process in two, a dominant and a satellite, interconnected markets. A simulated illustration of the model is also provided.

    Application of different dose levels of gamma radiation (0.25-3.0 KGy) on bolti fish resulted in remarkable suppression of the pathogenic organisms contaminating the samples. The D 10 values were found to be 0.31, 0.55 and 0.63 KGy for the Escherichia coli, Staphylococcus aureus and Streptococcus faecalis respectively. It has been found that the dose of 3.0 KGy is almost sufficient for 5 log cycles reduction of strept. faecalis being the most radio-resistant species of these organisms. Irradiation considerably decreased the numbers of salmonella typhimurium artificially contaminated the whole bolti fish and bolti fillets. The D 10 value of S.thyphimurium for whole bolti fillets. For the reduction of 5 log cycles of S.typhimurium, radiation dose levels of at least 4.50 KGy for the whole fish and 2.0 KGy for fish fillets were required

    Fish quality is traditionally controlled by chemical and microbiological analysis. The non-destructive control presents an enormous professional interest thanks to the technical contribution and precision of the analysis to which it leads. This paper presents the results obtained from a characterisation of fish thaw-ing process by the ultrasonic technique, with monitoring thermal processing from frozen to defrosted states. The study was carried out on fish type red drum and salmon cut into fillets of 15 mm thickness. After being frozen at -20°C, the sample is enclosed in a plexiglas vessel with parallel walls at the ambient temperature 30°C and excited in perpendicular incidence at 0.5 MHz by an ultrasonic pulser-receiver Sofranel 5052PR. the technique of measurement consists to study the signals reflected by fish during its thawing, the specific techniques of signal processing are implemented to deduce informations characterizing the state of fish and its thawing process by examining the evolution of the position echoes reflected by the sample and the viscoelastic parameters of fish during its thawing. The obtained results show a relationship between the thermal state of fish and its acoustic properties, which allowed to deduce the optimal time of the first thawing in order to restrict the growth of microbial flora. For salmon, the results show a decrease of 36% of the time of the second thawing and an increase of 10.88% of the phase velocity, with a decrease of 65.5% of the peak-to-peak voltage of the signal reflected, thus a decrease of the acoustic impedance. This study shows an optimal time and an evolution rate of thawing specific to each type offish and a correlation between the acoustic behavior of fish and its thermal state which approves that this technique of ultrasonic monitoring can substitute the control using the destructive chemical analysis in order to monitor the thawing process and to know whether a fish has suffered an accidental thawing.

    Smoking is widely used in fish processing for the color and flavor. Smoke flavorings have evolved as a successful alternative to traditional smoking. The hazards of the fish products treated by liquid-smoking process are discussed in this review. The smoke flavoring is one important ingredient in the smoke-flavored fish. This paper gives the definition of smoke flavorings and the hazard of polycyclic aromatic hydrocarbons (PAHs) residue in the smoke flavorings on the market. It gives also an assessment of chemical hazards such as carcinogenic PAHs, especially Benzo-[ a]pyrene, as well as biological hazards such as Listeria monocytogenes, Clostridium botulinum, histamine and parasites in smoke-flavored fish. The limitations in regulations or standards are discussed. Smoke flavored fish have lower content of PAHs as compared with the traditional smoking techniques if the PAHs residue in smoke flavorings is controlled by regulations or standards.

    Full Text Available Streptococcosis is one of the economically important diseases in the aquaculture industry particularly in rainbow trout aquaculture causing remarkable annual losses. Streptococcosis is known as a zoonotic disease causing morbidity and mortality in some consumers. In this study the status of farmed rainbow trout contamination with Streptococcus iniae and Lactococcus garvieae was assessed. For this reason, during summer months, 64 apparently diseased trout were sampled from fish markets of Tehran and Karaj. Gram staining was performed on grown colonies and then gram-positive cocci were further characterized using biochemical and PCR assays. The obtained results showed that 56.23% (36 samples of the samples were infected with the both bacterial pathogens. The prevalence of S. iniae and L. garvieae were 32.8 % (21 samples and 23.43% (15 samples, respectively. The highest and lowest prevalence rate of S. iniae was observed in the samples of Karaj (15.62% and Kahrizak (0% markets, respectively. In the case of L. garvieae, the highest and lowest rates were obtained in Karaj/Kahrizak (7.81% and Meidan-Nabi (1.56% markets, respectively. The results revealed that in some markets, the prevalence of streptococcosis and lactococcusis in cultured rainbow were relatively high. Therefore, it is necessary to conduct further trials.

    2014-08-01

    Fish processing plants still face microbial food safety-related product rejections and the associated economic losses, although they implement legislation, with well-established quality assurance guidelines and standards. We assessed the microbial performance of core control and assurance activities of fish exporting processors to offer suggestions for improvement using a case study. A microbiological assessment scheme was used to systematically analyze microbial counts in six selected critical sampling locations (CSLs). Nine small-, medium- and large-sized companies implementing current food safety management systems (FSMS) were studied. Samples were collected three times on each occasion (n = 324). Microbial indicators representing food safety, plant and personnel hygiene, and overall microbiological performance were analyzed. Microbiological distribution and safety profile levels for the CSLs were calculated. Performance of core control and assurance activities of the FSMS was also diagnosed using an FSMS diagnostic instrument. Final fish products from 67% of the companies were within the legally accepted microbiological limits. Salmonella was absent in all CSLs. Hands or gloves of workers from the majority of companies were highly contaminated with Staphylococcus aureus at levels above the recommended limits. Large-sized companies performed better in Enterobacteriaceae, Escherichia coli, and S. aureus than medium- and small-sized ones in a majority of the CSLs, including receipt of raw fish material, heading and gutting, and the condition of the fish processing tables and facilities before cleaning and sanitation. Fish products of 33% (3 of 9) of the companies and handling surfaces of 22% (2 of 9) of the companies showed high variability in Enterobacteriaceae counts. High variability in total viable counts and Enterobacteriaceae was noted on fish products and handling surfaces. Specific recommendations were made in core control and assurance activities

    Full Text Available The Hazard Analysis and Critical Control Point (HACCP system is scientifically based and focused on problem prevention in order to assure the produced food products are safe to consume. Prerequisite programs such as GMP (Good Manufacturing Practices, GHP (Good Hygienic Practices are an essential foundation for the development and implementation of successful HACCP plans. One of the preliminary tasks in the development of HACCP plan is to conduct a hazard analysis. The process of conducting a hazard analysis involves two stages. The first is hazard identification and the second stage is the HACCP team decision which potential hazards must be addressed in the HACCP plan. By definition, the HACCP concept covers all types of potential food safety hazards: biological, chemical and physical, whether they are naturally occurring in the food, contributed by the environment or generated by a mistake in the manufacturing process. In raw fish processing, potential significant biological hazards which are reasonably likely to cause illness of humans are parasites (Trematodae, Nematodae, Cestodae, bacteria (Salmonella, E. coli, Vibrio parahemolyticus, Vibrio vulnificus, Listeria monocytogenes, Clostridium botulinum, Staphyloccocus aureus, viruses (Norwalk virus, Entero virusesi, Hepatitis A, Rotovirus and bio-toxins. Upon completion of hazard analysis, any measure(s that are used to control the hazard(s should be described.

    Assessment of Committed Effective Dose (CED) due to consumption of marine fishes (Red Sea area) was performed in 33 different marine fish samples collected from the local market at Port sudan and classified according to their feeding habits into three categories: carnivores, herbivores, and omnivores. Activity concentrations of 210 Po and 137 Cs were determined and were found to range between 0.25 to 6.42 (carnivores), 0.7-5 (omnivores) and 1.5-3.8 (herbivores) Bq/Kg fresh w. for 210 Po and 0.1 to 0.46 (carnivores), 0.09 to 0.35 (omnivores) and 0.09 to 0.3 (herbivores) Bq/Kg fresh w. For 137 Cs which are several times lower than those of 210 Po. Appropriate conversion factors were used to derive the CED which was found to be 0.012, 0.01 and 0.01 (μ Sv/y) in carnivores, omnivores and herbivores, respectively, for 137 Cs, this contributes about 0.4% of the total dose. While for 210 Po, it was found to be 3.47, 4.81 and 4.14 (μ Sv/y) in carnivores, omnivores and herbivores, respectively which represents 99.6% of the total dose. The results of CED suggest that the dose received by Sudanese population from the consumption of marine fishes is rather small and the contribution of 137 Cs is negligible compared to 210 Po.

    Full Text Available In this paper, I examine the responses of 154 tourists in relation to their predisposition to purchase and the patterns and habits that are usually decisive in the decision making process regarding tourism services or products. For this research, I conducted a selective direct research, whose purpose was to obtain a segmentation of consumers who purchase tourism services based on specific dimensions of behavior. This research also implied studying the behavior of current and potential customers who purchase travel services depending on several variables for establishing different consumption habits. Thus, to establish a more detailed image of the tourists who participated in this direct and selective research, the analysis involved a factor analysis and a cluster analysis.

  5. Brokers and brokerage in the process of trading in commodity futures markets

    2003-01-01

    Full Text Available This paper mainly deals with the analysis of a very complex process of brokerage in commodity futures markets. Unlike a classical commodity market in which brokers are not a necessity, sales and purchases in commodity futures markets cannot be carried out without brokers. Brokers who act as agents of buyers and sellers of futures are a necessary condition for trading in organized markets, such as commodity futures markets. The structure of brokers in futures trading is multilayer and involves participants in futures trading from floor brokers, immediate futures traders and the members of clearing and the clearing house itself, on the one hand, to numerous other necessary actors whose activities out of the stock exchange and the clearing house contribute to the efficient functioning of futures market. The fact that transactions between buyers and sellers in futures markets are not carried out directly but through brokers means that the obligations of buyers and sellers are formally conveyed to brokers, providing at the same time the guarantee by the broker that the actual buyer and the actual seller will fulfill their contractual obligations. At the very beginning of futures trading, the relationship between the seller and the buyer is transformed into a relationship between two brokers. Since that moment on, the original relationship is conveyed to higher levels of brokerage reaching the level of the clearing house. In the process of transformation of the buyer-seller relationship and transmitting obligations and guaranteeing their fulfillment, the clearing house itself becomes the buyer relative to all sellers and the seller relative to all buyers. In this way, it guarantees that obligations regarding all transactions in futures market will be fulfilled. The whole process is carried out in accordance with the prescribed procedures conducted on the floor of commodity exchange, in its administrative departments and in the clearing house itself.

    Polonium-210 ( 210 Po), a short-lived member from the uranium series, is broadly distributed in Nature being among all alpha-emitters the major contributor to the internal dose in man. Studies of diets have shown that marine foods are important sources of this radionuclide. The levels of 210 Po have been determined in three highly consumed marine species, the fishes Sardinella brasiliensis (sardine) and Thunnus atlanticus (tuna), and the shrimp Litopenaeus brasiliensis, purchased from the Niteroi (RJ, Brazil) fish market, and caught along the coast of the state of Rio de Janeiro. Doses of 210 Po were determined for the entire organisms and for some tissues and organs, such as eyes, heart, gills, muscle, stomach liver, intestine and pyloric caecal (fishes) or eyes, head content, exoskeleton, muscle, hepatopancreas and pleopods. 210 Po is not uniformly distributed within these species, the highest levels being observed for sardine in the intestine (1634.6 mBq g-1), tuna in pyloric caecal (4656.1 mBq g-1) and shrimp in the hepatopancreas (1460.5 mBq g-1). The 210 Po activities in sardine, tuna and shrimp, calculated on a mean whole-organism basis, were 64.6, 34.5 and 39.5 Bq kg-1 (dry weight) respectively, with corresponding concentration factors of 7.2 x104, 3.8 x104 and 4.4 x104. Considering body distribution, almost 60% of the total activity is concentrated in the pyloric caecal of both fishes and in the hepatopancreas of the shrimp. In turn, the edible parts concentrate much less activity. (author)

    This research was conducted as a part of the continuous development of a novel technique for managing fish-processing wastewater by cultivating proteolytic yeast, Candida rugopelliculosa, as possible diet of the rotifer, Brachionus plicatilis. It was feasible to use Alaska Pollack processing wastewater as a growth medium for C. rugopelliculosa, which was stimulatory for growth of the rotifer by 18.3% over the commercial diet of Saccharomyces cerevisiae. Maximum growth of C. rugopelliculosa and reduction of influent soluble chemical oxygen demand (SCOD) concentration were respectively (6.09+/-0.04)x10(6) cells/ml and 70.0% at 6.3h hydraulic retention time (HRT). Method of 4th order Runge-Kutta approximation was successfully applied to determine the Monod kinetics of C. rugopelliculosa by using unsteady state data from only one continuous unsteady state operation at a fixed HRT. The maximum microbial growth rates, mu(max), and half saturation coefficient, K(s), were determined to be 0.82+/-0.22 h(-1) and 690+/-220 mg SCOD/L, respectively. The microbial yield coefficient, Y, and microbial decay rate coefficient, k(d), were determined to be (1.39+/-0.22)x10(4) cells/mg SCOD and 0.06+/-0.01 h(-1), respectively.

    Full Text Available Due to limited resources a company cannot serve all potential markets in the world in a manner that all the clients to be satisfied and the business goals achieved, which is why the company should select the most appropriate markets. It can focus on a single product market serving many geographic areas, but may also decide to serve different product markets in a group of selected geographic areas. Due to the large number and diversity of markets that can choose, analyze of the market attractiveness and the selection the most interesting is a complex process. General Electric Matrix/McKinsey has two dimensions, market attractiveness and the competitive strength of the firm, and aims to analyze the strengths and weaknesses of the company in a variety of areas, allowing the company to identify the most attractive markets and to guide managers in allocating resources to these markets, improve the weaker competitive position of the company in emerging markets, or to draw firm unattractive markets. We can say that it is a very efficient tool for the company being used by international market specialists, on one hand to select foreign markets for the company, and on the other hand, to determine the strategy that the firm will be using to internationalize on those markets. At the end of this paper we present a part of a larger study in which we showed how General Electric Matrix/McKinsey it is used specifically in select foreign markets.

    Full Text Available Oil price markets can benefit from a better considerate of how shocks can affect volatility through time. This study assesses the impact of structural changes and outliers on volatility persistence of two crude oil markets WTI and Brent oil price between January 1, 1996 and March 17, 2014. First, we identify the FIGARCH process proposed by Baillie et al. (1996 [Baillie, R.T., Bollerslev, T., & Mikkelsen, H.O., (1996, Fractionally integrated generalized autoregressive conditional heteroscedasticity. Journal of Econometrics, 74, 3-30.] and investigate some of its statistical proprieties and then incorporate this information into the volatility modelling. We also show that outliers can bias the estimation of the persistence of the volatility. Taking into account outliers on the volatility modelling process improve the understanding of volatility in crude oil markets.

  14. Optimal methodology for a machining process scheduling in spot electricity markets

    2010-01-01

    Electricity spot markets have introduced hourly variations in the price of electricity. These variations allow the increase of the energy efficiency by the appropriate scheduling and adaptation of the industrial production to the hourly cost of electricity in order to obtain the maximum profit for the industry. In this article a mathematical optimization model simulates costs and the electricity demand of a machining process. The resultant problem is solved using the generalized reduced gradient approach, to find the optimum production schedule that maximizes the industry profit considering the hourly variations of the price of electricity in the spot market. Different price scenarios are studied to analyze the impact of the spot market prices for electricity on the optimal scheduling of the machining process and on the industry profit. The convenience of the application of the proposed model is shown especially in cases of very high electricity prices.

    After the Chernobyl accident in April 1986, high levels of fish contamination with radiocesium were observed in different water-bodies in countries outside the former Sovet Union, particularly in some lakes in Scandinavia. Therefore, due to the high levels of radionuclide deposition in Ukraine, Belarus and Russia, high contamination in freshwater fish could be expected in these countries. It was considered that the contribution of the fish pathway to the individual and collective doses to the Ukrainian population was of lower significance in comparison with other pathways. However for local populations inhabiting contaminated areas, fish consumption could represent a higher risk. Large differences in contamination levels in fish were found in different water-bodies, and even in the same water-body between species. One of the important findings was the wide range of the levels of contamination within the same species by the 'size effect'. The European Commission was interested in reducing uncertainties in population doses estimates. Therefore the following studies, in collaboration between EU and CIS countries were started in 1992: laboratory experiments concerning the dependence of radiocesium biological half-life in fish upon the potassium concentration in water and food, water temperature and fish size; field studies in different water-bodies in Ukraine and Russia to understand the 'size-effect' and reveal the critical groups of population

    Pepsin is common digestive enzyme used for fish digestion in the laboratory to collect trematode metacercariae. In a field study, to survey the infected fish is needed a huge yield of pepsin and it is very expensive. Therefore, our purpose of this study was to investigate the candidate enzyme from pineapple juice which has a digestive enzyme called bromelain, a mixture of proteolytic enzymes, to digest fish in order to harvest metacercariae. Fish were divided into 2 groups: one group in which metacercariae were harvested using acid pepsin as a control and other groups in which the fish was digested using fresh pineapple juices. The results showed that pineapple juice is able to digest fish similarly to pepsin. The Pattavia pineapple juice had the highest number of metacercariae similar to the control. For Trat Si Thong pineapple juice, we found the number of metacercariae was less than control. This result suggests that the Pattavia pineapple juice was optimal juice for fish digestion to metacercaria collection and can be used instread of pepsin acid. PMID:28441786

    Methods to sample fishes in stream ecosystems and to analyze the raw data, focusing primarily on assemblage-level (all fish species combined) analyses, are presented in this chapter. We begin with guidance on sample site selection, permitting for fish collection, and information-gathering steps to be completed prior to conducting fieldwork. Basic sampling methods (visual surveying, electrofishing, and seining) are presented with specific instructions for estimating population sizes via visual, capture-recapture, and depletion surveys, in addition to new guidance on environmental DNA (eDNA) methods. Steps to process fish specimens in the field including the use of anesthesia and preservation of whole specimens or tissue samples (for genetic or stable isotope analysis) are also presented. Data analysis methods include characterization of size-structure within populations, estimation of species richness and diversity, and application of fish functional traits. We conclude with three advanced topics in assemblage-level analysis: multidimensional scaling (MDS), ecological networks, and loop analysis.

    Full Text Available This study was designed to estimate the economic analysis of locust bean processing and marketing in Ilorin, Kwara State, Nigeria. Primary data was used and purposive sampling technique was adopted to select the respondents used for the study. A total number of 60 respondents were interviewed. The data collected were analyzed using inferential statistical tool such as regression analysis. Budgetary analysis technique was also used to analyze the profitability of locust bean processing and marketing in the study area. Majority of the processors and marketers are making profits; 68.3% operate above breakeven point while 26.7% operate at breakeven point and the rest 5% was below the breakeven point, this indicates that they neither profit nor lost. The regression analysis result shows that quantity processed, family size and years of experience in processing are significant at 1%, 5% and 10% respectively while education level and stall rent is negative and significant at 1% and 5% respectively. F- Test also explained that independent variables are jointly significant at 1% probability level with an adjusted R2 of 78.9%. The overall rate of return on investment indicates that average rate of return is 0.5 (50%, which is positive. It is therefore concluded that profit made by the processors and marketers can be improved on by increasing the quantity of locust bean being processed through adoption of newly discovered method of processing and improved method of preservation, packaging and marketing of the product to international standard by reducing the odour of the product without the loss of essential nutrients and palability in order to generate foreign exchange. Also, rules and regulations against cutting of economic trees for alternative uses should be enforced to maximize their values.

    Various studies were conducted to determine the possibility of utilizing gamma irradiation to disinfect cowpea, maize, kola nuts and smoked fish in Nigeria. The studies included the determination of radiosensitivity of important storage insect pests such as the cowpea seed beetle, 'Callosobrucus maculatus', the cigarette beetle, 'Lasioderma serricorne', the kola weevils, 'Balanogastris kolae' and 'Sophrorhinus gbanjaensis'. They also included consumer acceptance and or sensory evaluation of irradiated cowpea, maize and smoked-dried fish. The results showed that irradiation could be integrated with the traditional peasant farmers' method of storing unshelled dry cowpea in granaries; and such an integration can completely eliminate seed beetle infestation. Irradiation at a dose of 0.2-1.0KGy was quite effective in preventing development of 'L. Serricorne'. All stages of development of 'B.kolae' and 'S. gbanjaensis' were very sensitive to irradiation; and a dose of 0.1KGy-0.2KGy was found to be adequate for disinfecting kola nut of the weevils. Irradiation up to 0.2KGy also did not cause any significant change in proximate composition of kola nuts. Consumer acceptance and sensory evaluation tests on cowpea, maize and smoke-dried fish showed that Nigerian consumers did not have any aversion to irradiated foods. A high percentage of respondents indicated their willingness to purchase samples

  10. The active electric sense of weakly electric fish: from electric organ discharge to sensory processing and behaviour

    Directory of Open Access Journals (Sweden)

    Krahe Rüdiger

    2016-01-01

    Full Text Available Sensory systems have been shaped by evolution to extract information that is relevant for decision making. In order to understand the mechanisms used by sensory systems for filtering the incoming stream of sensory input, it is important to have a quantitative understanding of the natural sensory scenes that are to be processed. Weakly electric fish lead a rather cryptic nocturnal life in often turbid tropical rainforest streams. They produce electric discharges and sense perturbations of their selfgenerated electric field for prey detection and navigation, and also use their active sense for communication in the context of courtship and aggression. The fact that they produce their electric signals throughout day and night permits the use of electrode arrays to track the movements of multiple individual fish and monitor their communication interactions, thus offering a window into their electrosensory world. This approach yields unprecedented access to information on the biology of these fishes and also on the statistical properties of the sensory scenes that are to be processed by their electrosensory system. The electrosensory system shares many organizational features with other sensory systems, in particular, the use of multiple topographic maps. In fact, the sensory surface (the skin is represented in three parallel maps in the hindbrain, with each map covering the receptor organ array with six different cell types that project to the next higher level of processing. Thus, the electroreceptive body surface is represented a total of 18 times in the hindbrain, with each representation having its specific filter properties and degree of response plasticity. Thus, the access to the sensory world of these fish as well as the manifold filtering of the sensory input makes these fish an excellent model system for exploring the cell-intrinsic and network characteristics underlying the extraction of behaviourally relevant sensory information.

    Little is known about early life diet as a risk factor for early-onset persistent conduct problems (EOP CP). To investigate this, we used data from the Avon Longitudinal Study of Parents and Children, a UK-based prospective epidemiological birth cohort. 5727 mother-child pairs (49.9 % boys) monitored since pregnancy (delivery date between 1 April, 1991 and 31 December, 1992) reported intake of fish and processed foods at 32 weeks gestation and, for the child, at 3 years; EOP (n = 666) and Low conduct problem (Low CP, n = 5061) trajectories were measured from 4 to 13 years; hyperactivity and emotional difficulties were assessed in childhood (4-10 years) and early adolescence (12-13 years), in addition to potential confounding factors (family adversity, birth complications, income). Compared to Low CP, mothers of EOP children consumed less fish (p processed food (p processed food at 3 years (p processed food (vs. less than one serving/day, p processed food, and low in fish, associate with an EOP CP trajectory and co-occurring difficulties in early adolescence. As small effect size differences were found, further studies are needed to investigate the long-term impact of early unhealthy diet.

    We model trading and price formation in a market under the assumption that order arrival and cancellations are Poisson random processes. This model makes testable predictions for the most basic properties of markets, such as the diffusion rate of prices (which is the standard measure of financial risk) and the spread and price impact functions (which are the main determinants of transaction cost). Guided by dimensional analysis, simulation, and mean-field theory, we find scaling relations in terms of order flow rates. We show that even under completely random order flow the need to store supply and demand to facilitate trading induces anomalous diffusion and temporal structure in prices.

  14. PRESERVATION OR DEGRADATION OF LOCAL CULTURAL ASSETS IN CENTRAL TOKYO – THE CASE OF THE PLANS TO RELOCATE THE TSUKIJI FISH MARKET

    Full Text Available Most cultural-led redevelopment projects in today’s global cities are devised with the clear objective of stimulating their economic growth. Redevelopment schemes usually aim to develop consumption services and urban settings to make the city more attractive for investors. In many cases, redevelopment has led to a diminishment in diversity of local cultural spaces in the inner-city areas. Historically and socially important services and institutions like Tokyo’s Tsukiji Fish Market tend to be relocated and replaced by less traditional and culturally less attractive spaces. This short-term strategy cannot really succeed in preserving or integrating local cultures, which may in the long run help Tokyo to become distinctively different from other global competing cities and to benefit from these advantages. The article analyses the plans to renovate or redevelop specific local consumption spaces in Tokyo, and explores what mechanisms and strategies are being used by the involved actors to accomplish their goals.

    This article provides an overview of the privatization of railway passengers market in Spain through a background to the most relevant cases studies in Europe, particularly the liberalization process in England. The English case study is a paradigmatic example to assess how the liberalization process was developed and its effect in the present. This assessment has been undertaken to analyse the railway franchise structure, ticketing measures, role of national and regional authorities, etc. and possible analogies to be adapted to the case of Spain. Firstly, this article reviews the origin of the privatization of the railway market in both Spain and England, describing every phase of the liberalization and the success of every stage. Secondly, a critical approach assessment exposes those market failures of the liberalization process in England that caused negative impacts on society. In addition, the role of the Government is analysed to measure their implication in order to solve that situation. Furthermore, the paper expounds a wide analysis of the rail ticketing in England, its effects on increased passenger number. Finally, this article proposes some measures to be followed on the privatization of passenger rail market in Spain, as well as some key concepts to guarantee its success as taken from the case studies that have been reviewed.

    A simple and effective method for the rapid determination of five salicylate and benzophenone-type UV absorbing substances in marketed fish is described. The method involves the use of matrix solid-phase dispersion (MSPD) prior to their determination by on-line silylation gas chromatography tandem mass spectrometry (GC-MS/MS). The parameters that affect the extraction efficiency were optimized using a Box-Behnken design method. The optimal extraction conditions involved dispersing 0.5g of freeze-dried powdered fish with 1.0g of Florisil using a mortar and pestle. This blend was then transferred to a solid-phase extraction (SPE) cartridge containing 1.0g of octadecyl bonded silica (C18), as the clean-up co-sorbent. The target analytes were then eluted with 7mL of acetonitrile. The extract was derivatized on-line in the GC injection-port by reaction with a trimethylsilylating (TMS) reagent. The TMS-derivatives were then identified and quantitated by GC-MS/MS. The limits of quantitation (LOQs) were less than 0.1ng/g. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Because escape from a net cage and mortality are constant problems in fish farming, health control and management of facilities are important in aquaculture. In particular, the development of an accurate fish counting system has been strongly desired for the Pacific Bluefin tuna farming industry owing to the high market value of these fish. The current fish counting method, which involves human counting, results in poor accuracy; moreover, the method is cumbersome because the aquaculture net cage is so large that fish can only be counted when they move to another net cage. Therefore, we have developed an automated fish counting system by applying particle tracking velocimetry (PTV) analysis to a shoal of swimming fish inside a net cage. In essence, we treated the swimming fish as tracer particles and estimated the number of fish by analyzing the corresponding motion vectors. The proposed fish counting system comprises two main components: image processing and motion analysis, where the image-processing component abstracts the foreground and the motion analysis component traces the individual's motion. In this study, we developed a Region Extraction and Centroid Computation (RECC) method and a Kalman filter and Chi-square (KC) test for the two main components. To evaluate the efficiency of our method, we constructed a closed system, placed an underwater video camera with a spherical curved lens at the bottom of the tank, and recorded a 360° view of a swimming school of Japanese rice fish (Oryzias latipes). Our study showed that almost all fish could be abstracted by the RECC method and the motion vectors could be calculated by the KC test. The recognition rate was approximately 90% when more than 180 individuals were observed within the frame of the video camera. These results suggest that the presented method has potential application as a fish counting system for industrial aquaculture.

    Full Text Available Contracting a licence is buying or selling contract of technology, design and marketing experiencerelating to a product or process, and involves the contracting of knowledge and know-how. The granting of aninternational licence takes place when a company provides, in return for a fee or royalties, technology needed byanother firm to run business operations on a foreign market. When in this form, the granting of the licencerequires at least one of the following items: a brand name; operating experience; manufacturing technology;access to patents and trade secrets/industrial. Company that grants the licence get access on a foreign marketwith very low investment and, in many cases, the benefits of investment and market knowledge of a competentlocal firms. The company that received the licence get access to foreign technology, with a very smallinvestment. There are several very obvious advantages of activity under the license on international markets.The granting of a licence can improve cash flow situation for the company that attaches. Because the license ontechnology allows companies to bring products to market faster, the company enjoys early advantage of apositive balance of cash flow. In addition, obtaining a license means lower development costs. The licensedactivity may mean fewer profits in the long run. Immediate benefits of easy access to new technology, lower costsand the development of an early cash flow are attractive advantages of contracting a licence.

    Full Text Available This paper addresses two principal issues: a the scale at which one examines urban segregation; and b how informality, specifically accessibility to land markets and the process of land appropriation by low-income groups in Latin American cities, influences segregation patterns. Using Mexico City as a case study for Latin America, it shows that macro residential segregation levels are not becoming more polarized as many believe, due to informality of the market place and the weak state intervention through planning and zoning. However, there is a hardening of boundaries between adjacent neighborhoods as people turn to gated communities, largely for security reasons. Case study material from three Mexican cities are presented to examine how the nature of residential land costs and market segmentation contributes to segregation in Latin American cities. In a second case study, data from peri-urban low-income self-build settlements (colonias in Texas cities demonstrate how existing inequality patterns can be reproduced by differential access to land markets. They further argue a case that such isolated (rural settlements serving nearby urban labor market, should also be included in any analysis of urban segregation patterns, even if they do not form part of the contiguous urban area.

    Full Text Available The analysis here developed is based on studies focusing on women’s participation in artisanal fishing, conducted in communities of the county of Canavieiras – BA. Women’s achievements regarding their insertion in the labor market have raised new issues and questions as to the production process in fishing communities, where women’s work is still marked by its invisibility and lack of recognition within the fishing category. Quite often, women’s work is regarded merely as an extension of their roles as mothers/wives/housewives which are superimposed upon their fishing activities. In many cases, for instance, the preparation of the fish by the women, for marketing purposes, even when adding value to the product, is regarded by both fishermen and fisherwomen as an extension of domestic tasks, precisely because is undertaken within the realms of their own homes.

    The main problem in boiled salted fish ikan pindang is mucus and mold on the surface of the fish which is produced relatively fast as well as the high level of histamine content especially when scombroid fish species are used as raw material. This study was performed to evaluate the effectiveness of various preservatives to overcome such problems. Three combinations of preservatives P1 (green tea and sorbate), P3 (green tea, piper betel, sorbate), P4 (green tea and piper betel) and P0 (no preservative/control) resulted from the previous study were used in this study. Before being used, the preservatives were tested against deteriorating microorganisms commonly found in boiled salted products, of which the result showed that all microorganisms were inhibited. The preservatives were then applied at three different stages of the process of boiled salted fish, i.e. before boiling, during boiling and after boiling. Sensory attributes and microbial characteristics of the products were then evaluated. The results showed that the performance of all tested preservatives against deteriorating microorganisms was relatively similar. It was also shown that the application before and during boiling performed better.

    In Langsa, fisheries are the sector leaders by fulfilling a capacity of about 6,050 tons per year and on the other hand, fish-aquaculture reaches 1,200 tons per year on average. The fish processing is conducted through catches and aquaculture. The facilities on which this processing takes place are divided into an ice factory unit, a gutting and cutting unit, a drying unit and a curing unit. However, the energy and electricity costs during the production process has become major constraint because of the increase in the fishermen’s production and income. In this study, the potential and cost-effectiveness of photovoltaic solar power plant to meet the energy demands of fish processing units have been analysed. The energy requirements of fish processing units have reached an estimate of 130 kW, while the proposed design of solar photovoltaic electricity generation is of 200 kW in an area of 0,75 hectares. In this analysis, given the closeness between the location of the processing units and the fish supply auctions, the assumption is made that the photovoltaic plants (OTR) were installed on the roof of the building as compared to the solar power plants (OTL) installed on the outside of the location. The results shows that the levelized cost of OTR instalation is IDR 1.115 per kWh, considering 25 years of plant life-span at 10% of discount rate, with a simple payback period of 13.2 years. OTL levelized energy, on the other hand, is at IDR 997.5 per kWh with a simple payback period of 9.6 years. Blood is an essential component of living creatures in the vascular space.

    2009-01-01

    Full Text Available Teleost fish possess similar nociceptive processing systems to those found in terrestrial vertebrates. It means that they react to potential painful stimuli in a similar manner as mammals and birds. However, the welfare of fish has been the focus of less research than that of higher vertebrates. Humans may affect the welfare of fish through fisheries, aquaculture and a number of other activities. There is scientific evidence to support the assumption that fish have the capacity to experience pain because they possess functional nociceptors, endogenous opioids and opioid receptors, brain structures involved in pain processing and pathways leading from nociceptors to higher brain structures. Also, it is well documented that some anaesthetics and analgesics may reduce nociceptive responses in fish. Behavioural indicators in fish such as lip-rubbing and rocking behaviours are the best proof that fish react to potential painful stimuli. This paper is an overview of some scientific evidence on fish capacity to experience pain.

    To objectively evaluate voluntary nutrition and health claims and marketing techniques present on packaging of high-market-share ultra-processed foods (UPF) in Australia for their potential impact on public health. Cross-sectional. Packaging information from five high-market-share food manufacturers and one retailer were obtained from supermarket and manufacturers' websites. Ingredients lists for 215 UPF were examined for presence of added sugar. Packaging information was categorised using a taxonomy of nutrition and health information which included nutrition and health claims and five common food marketing techniques. Compliance of statements and claims with the Australia New Zealand Food Standards Code and with Health Star Ratings (HSR) were assessed for all products. Almost all UPF (95 %) contained added sugars described in thirty-four different ways; 55 % of UPF displayed a HSR; 56 % had nutrition claims (18 % were compliant with regulations); 25 % had health claims (79 % were compliant); and 97 % employed common food marketing techniques. Packaging of 47 % of UPF was designed to appeal to children. UPF carried a mean of 1·5 health and nutrition claims (range 0-10) and 2·6 marketing techniques (range 0-5), and 45 % had HSR≤3·0/5·0. Most UPF packaging featured nutrition and health statements or claims despite the high prevalence of added sugars and moderate HSR. The degree of inappropriate or inaccurate statements and claims present is concerning, particularly on packaging designed to appeal to children. Public policies to assist parents to select healthy family foods should address the quality and accuracy of information provided on UPF packaging.

    2004-01-01

    Market liberalization has triggered fundamental changes in the electricity sector with far-reaching economic, technical, organizational and ecological consequences. The paper examines how electricity market liberalization has influenced innovation processes at the level of electric utilities and in the electricity sector as a whole. The results are based on an empirical survey including two case studies, green power and fuel cells, in which utility innovation strategies were analysed. From the similarities in both cases and the aggregated effects of innovation strategies, we identify several indications for a general change of innovation processes in the sector: the innovation activity has increased, there is a greater variety of innovation projects, product innovations and organizational innovations have gained importance, innovation networks have become smaller and more specific, and the professionalism of innovation management is improving.

    The most widely used method of reducing sulphur dioxide emission is flue gas desulphurisation (FGD). The combustion gases produced by large combustion units (for example power stations) are in contact with a liquid or a slurry containing a reactant for SO[sub 2]. This operation produces a waste gas which is essentially free of sulphur dioxide. This paper describes the steps involved in the research and development of the new Ispra FGD process. Details of market consideration are also given.

    Full Text Available The long–lasting process of adaptation of the Polish standardisation system to the conditions of the European Community has not beencompleted yet. Its logical consequence is the need to shape the mentality of the entrepreneurs and make them understand the importance of standards and their value in a competitive market. It is the intention of the authors of this study to disclose the main aspects of standardisation at both Polish and European level, explain the model of standardisation system currently functioning in Poland, and against this background highlight the priorities in the standardisation policy adopted by the European Union, especially as regards some specific subjects, including – among others – problems related with environmental protection and occupational safety. In standardisation system, the problems of occupational safety and environmental protection are dealt with by a large group of standards harmonised with the New Approach Directive, which touches on the safety–related issues. Our knowledge of standards speaking the language of business is the challenge of modern times that should not be rejected, as in many cases it determines our competitiveness in the common market. The synthetic knowledge comprised in standards creates conditions for good decisions supporting the process of company development, strengthening its position in the European market, and creating the image of a successful modern enterprise ready to start cooperation with other enterprises, making – moreover – an important contribution to the economic management of products manufactured by varioustechnological processes.

    New production processes and markets for alpha hemihydrate are discussed. Utility studies concluded that lignite gypsum is harmless in terms of public and occupational health, and is technically comparable to or superior to natural gypsum by virtue of greater purity. Semi-commercial and pilot-scale studies were carried out on the use of flue gas desulfurization (FGD) gypsum for producing alpha hemihydrate, with successful results. The process enabled pure alpha hemihydrate to be produced without dihydrate or dihydrate impurities, and of a constant, uniform quality. The treatment consists of forming pressed mouldings of FGD gypsum followed by steam autoclaving, drying and milling. Agents are used to stabilize the stackable moldings, and to act as growth inhibitors during transformation of dihydrite to alpha-hemihydrate. Markets for the product are found in mining, tunneling and road building, foundation work, floor systems, as hard plaster for dental and moulding applications, for construction industry use, and as structural and non-structural material. Details are presented of the production process and marketing concepts. 12 figs

    Full Text Available One source of ω-3 fatty acids is a by-product of lemuru canning processing that can be used for fortification.  Generally, fortification uses fish oil microcapsule but it is more expensive than direct fortification.  In this study, fish oil from a by-product of lemuru canning processing was directly fortified into beef meatball and chicken nugget at concentration of 0, 2, 4, and 6% (w/w.  Oxidation level, free fatty acid content, colour, lightness, texture, and sensory acceptance by triangle difference test were analyzed. The results showed that oxidation level of nugget was higher than meatball.  Free fatty acid content increased in nugget by increasing fortification level, but it was decrease in meatball. Texture of both was relatively unchanged, with a tendency to increase in nugget and decrease in meatball. Lightness (L of meatball surface was higher than nugget surface. Lightness did not significantly change by increasing fortification level. Redness (+a and yellowness (+b of meatball and nugget changed significantly by fortification. Difference test showed that fortification level of 2% was the highest level of fortification that taste and odor could not be distinguished with control by panelists. Best level of fish oil fortification was 2%. At 2% fortification, EPA was 2.85% for meatball, and 2.22% for nugget.  Sharp decline was occured in EPA and the decrease washigher in nugget than meatball.

  20. Honey Quality as Affected by Handling, Processing and Marketing Channels in Uganda

    Directory of Open Access Journals (Sweden)

    Nabakabya, D.

    2008-01-01

    Full Text Available The factors that affect honey quality in Uganda were surveyed in 120 beekeeping households. Honey was sampled from supermarkets, hawkers and stall markets along four transects across Kampala, the capital. Honey quality parameters assessed were diastase number (DN, free acidity (FA, moisture content (MC, hydroxymethylfurfural (HMF, and water insoluble solids (WIS. Honey was mostly harvested from basket and grass hives. Pressing, boiling and straining were popular honey processing methods. Honey quality was mainly compromised by harvesting immature honey, bad extraction methods and contamination by extraneous materials. Constraints to beekeeping were lack of appropriate equipment (52%, inadequate farmer skills, bad weather and vermin. Honey brands differed (P< 0.05 in DN, most failed the Uganda and Codex Alimentarius standards, and 20% met European Union HMF and DN standards. Correlation was observed between HMF vs. DN (r= 0.94; MC vs. FA (r= 0.56. Supermarket honey (4.65 was more superior (P< 0.05 in DN than stall markets (1.93, and hawkers (2.3. Similarly, WIS levels differed (P< 0.05 between honeys from supermarkets (0.08, stall markets (3.0 and hawkers (3.15. All honeys met MC standards, while DN and WIS were major shortcomings. Farmer training and extension in proper honey harvesting, handling and processing should be strengthened. Quality monitoring at all levels should be emphasized.

    The aim of this study was to determine the prevalence of various Salmonella serotypes in chickens, carcass contact surfaces as well as environmental samples collected from wet markets and small scale processing plant. A total of 182 poultry and environmental samples were collected at random on separate occasions from wet markets and small scale processing plant, during the period of October 2014 to July 2015 in Penang and Perlis, Malaysia. The samples were analyzed for the presence of Salmonella using ISO 6579:2002 conventional culture-based method. Presumptive Salmonella colonies were subjected to various biochemical tests (such as triple sugar iron and lysine iron test), serologically confirmed using polyvalent O and H antisera and further serotyped at Public Health Laboratory, Ministry of Health, Perak, Malaysia. Salmonella serotypes were isolated from 161 out of 182 samples (88.46%) with 100% prevalence in the whole chicken carcass and chicken cuts - as well as transport crate, cage, drum, knife, chopping board, display table, floor, bench wash water, wash water, and drain water. Salmonella was isolated from 91.67%, 83.33%, and 66.67% of defeathering machines, drain swabs, and apron, respectively. 17 serotypes were isolated in this study with Salmonella Albany (57/161), Salmonella Corvallis (42/161), and Salmonella Brancaster (37/161) being the predominant serovars. The most carcass contact and environmental samples collected along the wet market chicken processing line were consistently contaminated with Salmonella . This indicates that Salmonella has established itself in poultry processing environments by colonizing the surfaces of the equipment and survives in these environments by establishing biofilms. Our results highlight the need of implementing strict hygiene and sanitation standards to reduce the incidence of Salmonella . The prevalence of Salmonella in poultry can be reduced effectively by identifying and eliminating the sources and contamination

    Acceptability of radurized pasteurized by ionizing radiations or radappertized (sterilized by ionizing radiations) fishery products depends on the irradiated fish quality. Though the sensory test is subjective, it allows a correct estimate of the quality. The correlation that exists between the adulteration degree estimated by chemical tests (T.M.A., total volatile bases, total volatil acids) and the organoleptic quality of the product is very variable. Gamma irradiation causes both qualitative and quantitative changes in the microbial flora. Methods actually used for the quality determination are not very fiable: researchs have to be undertaken to improve them.

    Acceptability of radurized (pasteurized by ionizing radiation) or radappertized (sterilized by ionizin radiation) fishery products depends on the quality of fish irradiated. Though the organoleptic test is subjective, it allows a correct estimate of the quality. The correlation that exists between the adulteration degree estimated by chemical tests (T.M.A., total volatile bases, total volatile acids) and the organoleptic quality of the product is very variable. Further research is necessary to improve the methods currently used for quality determination. However, it can be assumed that the quality of radurized fish depends on its initial quality, storage time, preirradiation storage temperature and absorbed dose of radiation. Gamma irradiation causes both qualitative and quantitative changes in the microbial flora. Selective reduction in the microbial flora may be favourable to the development of Clostridium botulinum. This microorganism may produce toxins at refrigeration temperatures; radurization cannot eliminate the spores of Clostridium botulinum type E (the most often encountered in fish). Other food infection and food poisoning microorganisms like Salmonella species, Staphylococci and Enterococci survive radurization. Techniques such as irradiation on board, or combining refrigeration and irradiation may increase the storage life

    The chemical modifications and partitioning toward the brine phase (5% salt) of major phenol compounds of extra virgin olive oil (EVOO) were studied in a model system formed by sealed cans filled with oil-brine mixtures (5:1, v/v) simulating canned-in-oil food systems. Filled cans were processed in an industrial plant using two sterilization conditions commonly used during fish canning. The partitioning of phenolic compounds toward brine induced by thermal processing was studied by reversed-phase high-performance liquid chromatographic analysis of the phenol fraction extracted from oils and brine. Hydroxytyrosol (1), tyrosol (2), and the complex phenolic compounds containing 1 and 2 (i.e., the dialdehydic form of decarboxymethyl oleuropein aglycon 3, the dialdehydic form of decarboxymethyl ligstroside aglycon 4, and the oleuropein aglycon 6) decreased in the oily phase after sterilization with a marked partitioning toward the brine phase. The increase of the total amount of 1 and 2 after processing, as well as the presence of elenolic acid 7 released in brine, revealed the hydrolysis of the ester bond of hydrolyzable phenolic compounds 3, 4, and 6 during thermal processing. Both phenomena (partitioning toward the water phase and hydrolysis) contribute to explain the loss of phenolic compounds exhibited by EVOO used as filling medium in canned foods, as well as the protection of n-3 polyunsaturated fatty acids in canned-in-EVOO fish products.

    A chronic bioassay was carried out under laboratory conditions using juvenile Solea senegalensis to determine the toxicity of contaminants from an oil spill(Prestige). Also, the repair processes in fish affected by contaminants due to oil exposure were evaluated. Over 30 days individuals were exposed to clean sediment (control) and to sediment contaminated by a mixture of polyaromatic hydrocarbons (PAHs) and other substances. The physicochemical parameters of the tanks (salinity, temperature, pH and dissolved oxygen) were controlled during the exposure period. Clean sediment from the Bay of Cadiz (Spain) was used as negative control and was mixed with fuel oil to prepare the dilution (0.5% w:w dry-weight). After the exposure period, fish were labeled and transferred to "clean tanks" (tanks without sediment) in order to study the recovery and the repair processes in the exposed organisms. A biomarker of exposure (ethoxyresorufin-O-deethylase activity - EROD activity) and a biomarker of effect (histopathology) were analyzed during the exposure and recovery period. After 10, 20 and 30 days of exposure, individuals showed significant induction (P tank", enabled a first evaluation of the repair process of the induced damages due to the fuel oil exposure. After the recovery phase, control individuals showed a more significant decrease (P repair processes probably need longer recovery periods to observe significant improvement of the affected organs. This will be further investigated in the future.

    This paper reports the results of a preliminary evaluation of the potential domestic market for solar thermal energy supply technologies matched to industrial process heat applications. The study estimates current and projects future industrial process heat demand to the year 2030 by two-digit standard industrial classification code for the manufacturing industrial sector and discusses the potential to displace conventional fossil fuel sources such as natural gas with alternative sources of supply. The PC Industrial Model, used by DOE's Energy Information Administration in support of the National Energy Strategy (NES) is used for forecast industrial energy demand. Demand is disaggregated by census region to account for geographic variations in solar insolation, and by heat medium and temperature to facilitate end-use matching with appropriate solar energy supply technologies. Levelized energy costs (LEC) are calculated for flat plate collectors for low- temperature preheat applications, parabolic troughs for intermediate temperature process steam and direct heat, and parabolic dish technologies for high-temperature, direct heat applications. LEC is also developed for a conventional natural gas-fueled Industrial Process Heat (IPH) supply source assuming natural gas price escalation consistent with NES forecasts to develop a relative figure of merit used in a market penetration model

    Full Text Available Each year research institutes develops many new technologies. Understanding the process of developing and bringing new technologies to market is important for researchers and managers of research organizations. Condense the technology development process and keeping its quality is one of the major strategic challenges within the research institute. The only way is to assure a better interaction of the main process steps of the new technology development process: Research, Development, Engineering, Production and Operation. This could save time, reduce cost and potentially even improve the quality of the outputs. Since NPD process in manufacturing companies is similar to NTD process in research organizations, the NPD paradigm provided a natural starting point for the commercialization process of new technologies. We describe the technology development process based on a review of the literature and web sites addressing NPD processes and policies. Our research effort is to better understand the steps prevalent in the new technology development process and we use a process modeling technique, namely, Process Approach View in our study. The main limit of this study are lack of material in the literature and the a lack of a system level understanding of the dynamics of the technology development process, both from management and process perspectives among researchers and managers of research organizations. This model has an integrated approach into a holistic development process of a technology and consists of various research and development (R&D activities. The model performs better ’predictions of R&D projects’ technical and commercial success and has the potential to be used as a conducting model for research projects in research organizations.

  14. Reliability through markets in Ontario : submission by the Independent Electricity Market Operator to the Minister of Energy's Consultation Process

    International Nuclear Information System (INIS)

    2003-01-01

    For the past five years, Ontario has invested $1 billion to restructure and open its electricity market to competition. In recent months, and in response to residential consumers pricing concerns, the Independent Electricity Market Operator (IMO) transferred credits to local distribution companies allowing them to issue $75 rebates to all affected customers as of December 1, 2002, and to bill low-volume and other designated customers at a rate of 4.3 cents per kilowatt hour for the commodity portion of their bills. This report addresses the concern that price responsiveness will be lost for those parts of the market with fixed prices. It was noted that the reliability of the power system could be placed at risk if the range of customers with fixed prices is broadened. Fixed prices would also jeopardize the province's ability to attract new supply and enhance competition in the electricity sector. The IMO believes that price responsiveness in the wholesale market is crucial to the reliability of the electricity system and recommends that a plan for any additional fixed pricing should include a clearly defined phase-out over the period ending in 2006 as new supply comes on-line. The IMO emphasizes that the lack of price responsiveness to the market, particularly in peak energy demand periods, is equivalent to adding hundreds of MW to the load. The report presents lessons learned in other jurisdictions and highlights noteworthy considerations such as the market power mitigation agreement, improving competition, a phased-in approach, and demand side initiatives

In Chinese 3G telecommunication market, there are three oligopolistic competitors. In order to study competing process of the triopoly, the paper considered a Bertrand model with bounded rational. A triopoly game is modeled by three nonlinear difference equations. By using the theory of bifurcations of dynamical systems, the existence and stability for the equilibria of this system were obtained. Numerical simulations were used to show bifurcations diagrams, the maximum Lyapunov exponent and sensitive dependence on initial conditions. We observed that increasing the speed of adjustment of bounded rational player might change the stability of Nash equilibrium point and cause bifurcation and chaos to occur. Thus, it will be difficult to make strategy and to forecast for each enterprise. It might cause the telecom markets to be irregular. The analysis and results in this paper are important for Chinese telecommunication markets, the same to mathematics.

The objective was to determine the characteristics of relationship marketing as a key factor in the process of Customer Loyalty in the big construction of Manizales Colombia. From a joint perspective, methodology relies on instruments and qualitative and quantitative analysis of court. The results tend to confirm that developers recognize the importance of Relational Marketing but not raised as a policy or have not defined in its strategic plan; additionally, expressed lack of strategies for customer retention, however, these remain loyal because the construction work on meeting your needs, based on trust, commitment and communication. To conclude, the faithful customers perceive that construction does not periodically evaluate their satisfaction with the purchased product, also claim that they show little interest in understanding the perception, make personal meetings, making constant communication through phone calls and meet their tastes and preferences.

    In the present study, we evaluated the changes in quality that can occur during the distribution of nonheated anchovy ( Engraulis japonicus) fish sauce after packaging. The pH values of all samples ranged from 5.5 to 5.8, and there were no significant differences ( P > 0.05) in pH among the samples during storage regardless of storage temperature or salt concentration. The initial total volatile base nitrogen concentration in all samples after bottling was 115 to 121 mg/100 mL, but this concentration increased gradually with storage time. After 1 year of storage, total volatile base nitrogen concentration had increased to approximately 170% of the initial concentration (166 to 194 mg/100 mL). Amino nitrogen increased slightly during storage but was significantly lower than the increase in amino nitrogen during general anchovy fish sauce fermentation with anchovy flesh. Most of the free amino acids increased slightly during the storage period regardless of storage temperature or salt concentration, but tyrosine and histidine increased and then decreased during the storage period. The histamine concentration of the anchovy fish sauce at a salt concentration of 20% was 43.3 mg/100 mL initially, but after 1 year the histamine concentration was 89.7 mg/100 mL in samples stored at 10°C, 102.6 mg/100 mL in samples stored at 25°C, and 116.8 mg/100 mL in samples stored at 35°C . Changes in putrescine and cadaverine concentrations were similar to those in histamine; concentrations increased about twofold from the initial concentrations after 1 year of storage. However, the rate of increase in putrescine from 4 months after storage was very high, and cadaverine slightly decreased by 12 months of storage. High scores for umami and aroma sensory characteristics were given to samples stored at 10°C, but samples stored 35°C were given high scores for rancid. Despite the overall low scores for aroma and umami for samples stored at 35°C, the quality of the anchovy fish sauce

    Gamma irradiation causes both qualitative and quantitative changes in the microbial flora. Selective reduction in the microbial flora may be favourable to the development of Clostridium botulinum. This microorganism is able to produce toxins at refrigeration temperatures and the radurization is not able to eliminate the spores of Clostridium botulinum type E (the most often encountered in fish). Other food infection and food poisoning microorganisms like Salmonella species, Staphylococci and Enterococci survive radurization. Techniques such as irradiation on board, or combining refrigeration and irradiation may increase the keeping quality time. Public health and economical aspects have to be examined thoroughly [fr

    The present study was undertaken to investigate the possible effects of Fe and trace element exposure on hepatic levels of retinoids in seven fish species. Concentrations of retinoids were measured in fish collected from a coastal lagoon in Brazil that receives effluents from an iron-ore mining and processing plant. Fish from nearby coastal lagoons were also included to assess possible differences related to chemical exposure. Results indicated considerable differences in hepatic retinoid composition among the various species investigated. The most striking differences were in retinol and derivative-specific profiles and in didehydro retinol and derivative-specific profiles. The Perciformes species Geophagus brasiliensis, Tilapia rendalli, Mugil liza, and Cichla ocellaris and the Characiforme Hoplias malabaricus were characterized as retinol and derivative-specific, while the Siluriformes species Hoplosternum littorale and Rhamdia quelen were didehydro retinol and derivative-specific fish species. A negative association was observed between Al, Pb, As, and Cd and hepatic didehydro retinoid levels. Fish with higher levels of hepatic Fe, Cu, and Zn showed unexpectedly significant positive correlations with increased hepatic retinol levels. This finding, associated with the positive relationships between retinol and retinyl palmitate with lipid peroxidation, may suggest that vitamin A is mobilized from other tissues to increase hepatic antioxidant levels for protection against oxidative damage. These data show significant but dissimilar associations between trace element exposure and hepatic retinoid levels in fish species exposed to iron-ore mining and processing effluents, without apparent major impacts on fish health and condition.

    This article presents the links between technique, commerce and consumption in fishing for zazamushi, a mixture of aquatic insect larvae sold as food souvenirs in Japan. Since zazamushi are mainly collected for economic reasons, we suggest that demand for them has incited technical development among collectors in order to fish more insects. Several fishermen and traders were interviewed in semi-directed interviews about their practices and knowledge. To understand the passage from a faunal composition to a commercial composition, our research follows a fishing session closely, as well as the selection of insects that follows it. The insects collected were separated from inanimate matter, then identified, counted and weighed at each stage of the process. Our results suggest that the current technique corresponds to an evolution in subsistence and recreational collecting towards a more systematic fishing of the insects, the aim of which is commercial. In their response to trade issues, the collectors have moved away from the banks to fish the insects in the river current, thus increasing the amount of one species captured compared to another. Although the technique is efficient (and similar to other harvesting techniques), it requires the thorough sorting of organic debris and insects (in our example, the catch contains approximately 78 % of inanimate matter and 22 % of insects, of which 3.29 % are retained for consumption, i.e., less than 2 out of 100 insects). The selection of insects to be consumed takes place mainly during cleaning. This stage depends on traders and reflects the different compositions sold as souvenirs. Our research shows that the consumption of insects is not explained just by ecological factors that are favourable or unfavourable, but also by technological and economic factors related to their commerce. It suggests that the traders have gradually established the insects that are currently sold as zazamushi and that this commercial development

    Emerging literature suggests that men's diets may affect spermatogenesis as reflected in semen quality indicators, but literature on the relation between meat intake and semen quality is limited. Our objective was to prospectively examine the relation between meat intake and indicators of semen quality. Men in subfertile couples presenting for evaluation at the Massachusetts General Hospital Fertility Center were invited to participate in an ongoing study of environmental factors and fertility. A total of 155 men completed a validated food-frequency questionnaire and subsequently provided 338 semen samples over an 18-mo period from 2007-2012. We used linear mixed regression models to examine the relation between meat intake and semen quality indicators (total sperm count, sperm concentration, progressive motility, morphology, and semen volume) while adjusting for potential confounders and accounting for within-person variability across repeat semen samples. Among the 155 men (median age: 36.1 y; 83% white, non-Hispanic), processed meat intake was inversely related to sperm morphology. Men in the highest quartile of processed meat intake had, on average, 1.7 percentage units (95% CI: -3.3, -0.04) fewer morphologically normal sperm than men in the lowest quartile of intake (P-trend = 0.02). Fish intake was related to higher sperm count and percentage of morphologically normal sperm. The adjusted mean total sperm count increased from 102 million (95% CI: 80, 131) in the lowest quartile to 168 million (95% CI: 136, 207) sperm in the highest quartile of fish intake (P-trend = 0.005). Similarly, the adjusted mean percentages of morphologically normal sperm for men in increasing quartiles of fish intake were 5.9 (95% CI: 5.0, 6.8), 5.3 (95% CI: 4.4, 6.3), 6.3 (95% CI: 5.2, 7.4), and 7.5 (95% CI: 6.5, 8.5) (P-trend = 0.01). Consuming fish may have a positive impact on sperm counts and morphology, particularly when consumed instead of processed red meats. © 2014 American

    Currently, one of the major problem affecting the world is solid waste management, predominantly petroleum-based plastic and fish solid waste (FSW). However, it is very difficult to reduce the consumption of plastic as well as fish products, but it is promising to convert FSW to biopolymer to reduce eco-pollution. On account of that, the bioconversion of FSW extract to polyhydroxybutyrate (PHB) was undertaken by using Bacillus subtilis (KP172548). Under optimized conditions, 1.62 g/L of PHB has been produced by the bacterium. The purified compound was further characterized by advanced analytical technologies to elucidate its chemical structure. Results indicated that the biopolymer was found to be PHB, the most common homopolymer of polyhydroxyalkanoates (PHAs). This is the first report demonstrating the efficacy of B. subtilis to utilize FSW extract to produce biopolymer. The biocompatibility of the PHB against murine macrophage cell line RAW264.7 demonstrated that, it was comparatively less toxic, favourable for surface attachment and proliferation in comparison with poly-lactic acid (PLA) and commercially available PHB. Thus, further exploration is highly indispensable to use FSW extract as a substrate for production of PHB at pilot scale.

    The identification of fish species in transformed food products is difficult because the existing methods are not adapted to heat-processed products containing more than one species. Using a common to all vertebrates region of the cytochrome b gene, we have developed a denaturing high-performance liquid chromatography (DHPLC) fingerprinting method, which allowed us to identify most of the species in commercial crab sticks. Whole fish and fillets were used for the creation of a library of referent DHPLC profiles. Crab sticks generated complex DHPLC profiles in which the number of contained fish species can be estimated by the number of major fluorescence peaks. The identity of some of the species was predicted by comparison of the peaks with the referent profiles, and others were identified after collection of the peak fractions, reamplification, and sequencing. DHPLC appears to be a quick and efficient method to analyze the species composition of complex heat-processed fish products.

    The imbalance of the n-3/n-6 ratio in the Western diet is characterised by a low intake of n-3 long-chain (LC) PUFA and a concurrent high intake of n-6 PUFA. Fish, in particular marine fish, is a unique source of n-3 LC PUFA. However, FA composition of consumed fish changed, due to the increasing usage of n-6 PUFA-rich vegetable oils in aquaculture feed and in fish processing (frying) which both lead to a further shift in n-6 PUFA to the detriment of n-3 LC PUFA.The aim of this study was to determine the ratio of n-3/n-6 including the contents of EPA and DHA in fish fillets and fish products from the German market (n=123). Furthermore, the study focussed on the FA content in farmed salmon compared to wild salmon as well as in processed Alaska pollock fillet, e.g., fish fingers. Total fat and FA content in fish products varied considerably depending on fish species, feed management, and food processing. Mackerel, herring and trout fillets characteristically contained adequate dietary amounts of absolute EPA and DHA, due to their high fat contents. However, despite a lower fat content, tuna, pollock, and Alaska pollock can contribute considerable amounts of EPA and DHA to the human supply.Farmed salmon are an appropriate source of EPA and DHA owing to their higher fat content compared to wild salmon (12.3 vs. 2.1 wt %), however with elevated SFA, n-9 and n-6 FA contents representing the use of vegetable oils and oilseeds in aquaculture feed. The n-3/n-6 ratio was deteriorated (2.9 vs. 12.4) but still acceptable. Compared to pure fish fillets, breaded and pre-fried Alaska pollock fillet contained extraordinarily high fat and n-6 PUFA levels. Since fish species vary with respect to their n-3 LC PUFA contents, eating a variety of fish is advisable. High n-6 PUFA containing pre-fried fish support the imbalance of n-3/n-6 ratio in the Western diet. Thus, consumption of pure fish fillets is to be favoured. The lower n-3 PUFA portion in farmed fish can be offset by the

    Organochlorine pesticide residues and polychlorinated biphenyls were determined in raw materials, fish feeds and fillets from fish exposed through the productive cycle (14 months) to experimental diets with different percentages of fish oil replacement with vegetable oils. Detectable amounts of organochlorine compounds were found in raw materials derived from fish sources with none being detected in vegetable ingredients. Fish feeds presented trace concentrations of contaminants at the ng/g level, which varied according to the contribution of the different resources used in their manufacture. Contaminants did not accumulate during the first 11 months of exposure, and low concentrations of organochlorine compounds were found both at the start and at the end of this feeding period. Fillets from fish fed the fish oil diet presented the highest concentrations of organochlorine compounds, with these decreasing in proportion to fish oil replacement. Three months of fish oil re-feeding during the finishing phase only produced significant bioaccumulation over the course of the first month. By optimizing fish meal and fish oil replacement with vegetable oils alternative feeds can contribute to significantly reduce the risk of organochlorine uptake by consumers.

    Some technological and food processing treatments applied to parasitized fish kill the Anisakis larvae and prevent infection and sensitization of consumers. However, residual allergenic activity of parasite allergens has been shown. The aim here was to study the effect of different heat treatments used in the fish canning processing industry on the antigen recognition of Anisakis L3. Bigeye tuna (Thunnus obesus) and yellowfin tuna (Thunnus albacares) were experimentally infected with live L3 Anisakis. After 48 h at 5 ± 1 °C, brine was added to the muscle, which was then canned raw (live larvae) or heated (90 °C, 30 min) (dead larvae) and treated at 113 °C for 60 min or at 115 °C for 90 min. Anisakis antigens and Ani s 4 were detected with anti-crude extract and anti-Ani s 4 antisera respectively. Ani s 4 decreased in all lots, but the muscle retained part of the allergenicity irrespective of the canning method, as observed by immunohistochemistry. Dot blot analysis showed a high loss of Ani s 4 recognition after canning, but residual antigenicity was present. The results indicate that heat treatment for sterilization under the conditions studied produces a decrease in Ani s 4 and suggest a potential exposure risk for Anisakis-sensitized patients. © 2014 Society of Chemical Industry.

    Colombia is one of the countries where a restructuring process of the electricity industry has taken place in the recent years. The reforms introduced since the beginning of the present decade, have resulted in deep changes into this sector. Such a process seeks to create a competitive sector to manage the profound crisis that has pervaded the electricity supply in Colombia since the 80`s. The adopted model contains several of the elements needed to achieve economic efficiency: Unbundling, competition on generation and on the retail market, open access to electricity networks and regulatory mechanisms in whose activities where a natural monopoly takes place. The aim of this article is to show the Colombian experience in implementing and managing structural changes in the electricity market. (orig.)

    This paper provides an in-depth, qualitative analysis of the physicians' decision process for drug prescription. Drugs in the considered therapeutic classes are mainly prescribed by specialists, treating patients with obligatory medical insurance, for a prolonged period of time. The research approach is specifically designed to capture the full complexity and sensitive nature of the physician's choice behavior, which appears to be more hybrid and less rational in nature than is often assumed in quantitative, model-based analyses of prescription behavior. Several interesting findings emerge from the analysis: (i) non-compensatory decision rules seem to dominate the decision process, (ii) consideration sets are typically small and change-resistant, (iii) drug cost is not a major issue for most physicians, (iv) detailing remains one of the most powerful pharmaceutical marketing instruments and is highly appreciated as a valuable and quick source of information, and (v) certain types of non-medical marketing incentives (such as free conference participation) may in some situations also influence drug choices.

    Reported fish allergy prevalence varies widely, with an estimated prevalence of 0.2% in the general population. Sensitization to fish can occur by ingestion, skin contact or inhalation. The manifestations can be IgE or non-IgE mediated. Several fish allergens have been identified, with parvalbumins being the major allergen in various species. Allergenicity varies among fish species and is affected by processing or preparation methods. Adverse reactions after eating fish are often claimed to be 'allergy' but could be a reaction to hidden food allergen, fish parasite, fish toxins or histamine in spoiled fish. Identifying such causes would allow free consumption of fish. Correct diagnosis of fish allergy, including the specific species, might provide the patient with safe alternatives. Patients have been generally advised for strict universal avoidance of fish. However, testing with various fish species or preparations might identify one or more forms that can be tolerated.

    Full Text Available For the Czech insurance industry, it has been 13 years since the passage of the Insurance Act in 1991, which did away with the monopoly and allowed competition in this business sector. In our evaluation, we can state that the positives outweigh the negatives. A relatively high pace of growth in total premiums written was achieved and the ratio of premiums written to GDP increased, up to 4,0% in 2002. In comparison with EU countries, the Czech insurance market is behind in 2 global indicators: the ratio of premiums written to GDP and the share of life insurance in total premiums written. The Czech insurance market must count on greater competition from foreign insurance companies, as the Czech Republic was May 1, 2004, accepted as a member of the European Union.

    In this article, we investigate conditional mean and conditional variance forecasts using a dynamic model following a k-factor GIGARCH process. Particularly, we provide the analytical expression of the conditional variance of the prediction error. We apply this method to the German electricity price market for the period August 15, 2000-December 31, 2002 and we test spot prices forecasts until one-month ahead forecast. The forecasting performance of the model is compared with a SARIMA-GARCH benchmark model using the year 2003 as the out-of-sample. The proposed model outperforms clearly the benchmark model. We conclude that the k-factor GIGARCH process is a suitable tool to forecast spot prices, using the classical RMSE criteria. (author)

    Toxin formation by proteolytic and nonproteolytic strains of C. botulinum type B in radurized raw fish and in radurized Pindang fish was investigated. In radurized Pindang fish samples, inoculation was done either before or after cooking. Radurization process with 2 and 3 kGy caused the extension of storage life of Rastrelliger sp., Euthynnus sp., and Scomberomorus sp. by factors of 2 and 2.5 at storage temperatures between 5 and 10 0 C. In general at 10.5 +- 0.3 0 C, no toxin was formed before the samples were spoiled both in irradiated and unirradiated samples. At 5.6 +- 0.5 0 C no toxin was formed until after the samples were spoiled. The earliest toxin formation in unirradiated Pindang samples stored at ambient temperature was detected after the samples were spoiled. In irradiated Pindang samples inoculated with C. botulinum spores after cooking and stored at ambient temperature the toxin formation was detected before the samples were spoiled. However, if the inoculation was done before the fish was processed into Pindang, the toxin was always detected after the samples were spoiled regardless of the irradiation dose, strain and inoculation level. As fish may be contaminated - if at all - with spores of C. botulinum in its raw state, processing of fish into Pindang and irradiation would not contribute to the health hazard concerning botulism even if the samples are stored at ambient temperature

    Full Text Available It has been determined that investment processes in the IT market enable the development and efficient use of affordable investment resources to develop and ensure the competitiveness of market players. Different approaches to interpretation of essence of investment processes have been identified. It has been proven that in order to implement an effective public policy in the IT services market, investment process must be seen as a macroeconomic system of relationships in the formation, attraction and use of investments in the IT services market, implementation of investment projects by the IT business entities. With that, systematic approach to understanding investment process brings to the fore an awareness of its typology, which in turn affects the applied instruments and means of public investment policy in this sphere. It has been found that the characteristics of governmental regulation of investment processes in the market for IT services are first and foremost determined by the aspects of the market functioning, the selected objects of trade, the basic constituents of investment activity, and the institutional framework.

    Food basket surveys and exposure studies conducted over the past decade suggest that one of the main routes of human exposure to polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) and biphenyls (PCBs) is likely through the consumption of food products such as eggs, meats, fish, and dairy products. More recently, studies of human milk, blood, and adipose tissues also demonstrate human exposure to polybrominated diphenyl ethers (PBDEs). The contamination of Belgium store-bought chicken products in 1999 and, more recently, concerns regarding farmraised fish products in the U.S., Ireland, and elsewhere by PCDD/Fs and PCBs has heightened concerns about the occurrence of other persistent organic pollutants (POPs), including PBDEs, in consumer food products. In the U.S., for example, recent studies have shown the edible portions of farm-raised fish containing higher levels of PCDD/Fs, PCBs, and PBDEs than in wild fish. In this study, fillets from several species of freshwater and ocean fish (both farm-raised and wild), as well as ground beef, ground deer, and meat from several species of fowl (chicken, turkey, duck, goose, and pheasant), were purchased from food markets in the cities of Sacramento and El Dorado Hills, California USA. Foods were tested for PCDD/Fs, PCBs, and PBDEs and the results used to evaluate human exposure through the consumption of store-bought consumer food products.

    The central nervous system, and the brain in particular, is one of the most remarkable products of evolution. This system allows an individual to acquire, process, store and act on information gathered from the environment. The resulting flexibility in behavior beyond genetically coded strategies is a prime adaptation in animals. The field of animal cognition examines the underlying processes and mechanisms. Fishes are a particularly interesting group of vertebrates to study cognition for two...

    Peanut is succeptable to aflatoxin contamination and the sources of peanut as well as processing methods considerably affect aflatoxin content of the products. Therefore, the study on aflatoxin and nutrient contents of peanut collected from local market and their processed foods were performed. Good kernels of peanut were prepared into fried peanut, pressed-fried peanut, peanut sauce, peanut press cake, fermented peanut press cake (tempe) and fried tempe, while blended kernels (good and poor kernels) were processed into peanut sauce and tempe and poor kernels were only processed into tempe. The results showed that good and blended kernels which had high number of sound/intact kernels (82,46% and 62,09%), contained 9.8-9.9 ppb of aflatoxin B1, while slightly higher level was seen in poor kernels (12.1 ppb). However, the moisture, ash, protein, and fat contents of the kernels were similar as well as the products. Peanut tempe and fried tempe showed the highest increase in protein content, while decreased fat contents were seen in all products. The increase in aflatoxin B1 of peanut tempe prepared from poor kernels > blended kernels > good kernels. However, it averagely decreased by 61.2% after deep-fried. Excluding peanut tempe and fried tempe, aflatoxin B1 levels in all products derived from good kernels were below the permitted level (15 ppb). This suggests that sorting peanut kernels as ingredients and followed by heat processing would decrease the aflatoxin content in the products.

    Genetically modified maize MON863 (MON863), which has passed a safety examination in Japan, is commercially cultivated in the United States as a food and a resource for fuel. Maize is an anemophilous flower, which easily hybridizes. However, an official method for quantifying the content of MON863 has not been provided yet in Japan. We here examined MON863 contamination in maize-processed foods that had no labeling indicating of the use of genetically modified maize.From March 2006 to July 2008, we purchased 20 frozen maize products, 8 maize powder products, 7 canned maize products and 4 other maize processed foods. Three primer pairs named MON 863 primer, MON863-1, and M3/M4 for MON863-specific integrated cassette were used for qualitative polymerase chain reaction (PCR). A primer pair "SSIIb-3" for starch synthase gene was used to confirm the quality of extracted DNA. The starch synthase gene was detected in all samples. In qualitative tests, the MON863-specific fragments were detected in 7 (18%) maize powder products out of the 39 processed foods with all the three primer pairs.We concluded that various maize processed foods on the market were contaminated with MON863. It is important to accumulate further information on MON863 contamination in maize-processed foods that have no label indication of the use of genetically modified maize.

    Bicycle injuries are of concern in Canada. Since helmet use was mandated in 1996 in the province of British Columbia, Canada, use has increased and head injuries have decreased. Despite the law, many cyclists do not wear a helmet. Health action process approach (HAPA) model explains intention and behaviour with self-efficacy, risk perception, outcome expectancies and planning constructs. The present study examines the impact of a social marketing campaign on HAPA constructs in the context of bicycle helmet use. A questionnaire was administered to identify factors determining helmet use. Intention to obey the law, and perceived risk of being caught if not obeying the law were included as additional constructs. Path analysis was used to extract the strongest influences on intention and behaviour. The social marketing campaign was evaluated through t-test comparisons after propensity score matching and generalised linear modelling (GLM) were applied to adjust for the same covariates. 400 cyclists aged 25-54 years completed the questionnaire. Self-efficacy and Intention were most predictive of intention to wear a helmet, which, moderated by planning, strongly predicted behaviour. Perceived risk and outcome expectancies had no significant impact on intention. GLM showed that exposure to the campaign was significantly associated with higher values in self-efficacy, intention and bicycle helmet use. Self-efficacy and planning are important points of action for promoting helmet use. Social marketing campaigns that remind people of appropriate preventive action have an impact on behaviour. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available In this study, it is aimed to investigate the criteria affecting the marketing of barley in the stages of barley production, marketing and processing in Konya province. In the study; survey results were used which get from mixed feed (37 items and malt factory (1 item, traders (50 items purchasing and selling barley, and agricultural enterprises (107 items including barley production in agricultural activities operating in Konya province. It was determined that barley varieties were not an important criterion in the selling price, while the hectoliter and other plant species do not mix into barley are the main criteria considered by agricultural enterprises to affect the sale of barley. The most important criteria that traders keep in mind when buying barley is hectoliter of barley, which is followed by moisture, colour and foreign matter confusion rate of barley. The most important criteria that factories take into consideration when purchasing barley is determined as the moisture content of the barley, followed by the hectoliter of barley and the rate of foreign matter contamination. For the malt industry; Barley variety is a very important factor in the purchase criteria, followed by barley humidity and colour.

  14. The market of nuclear plant dismantling. The new EDF's strategy, process standardisation, robotization: which perspectives for the market by 2030?

    International Nuclear Information System (INIS)

    2017-09-01

    Dismantling appears as the most promising activity in the nuclear sector due to ageing plants, to ambitious objectives of reduction of the nuclear share in the energy mix, or to high expertise of French companies in robotic and digital solutions for deconstruction in radioactive environments. However, the development of the dismantling market depends on EDF decisions: the extension of nuclear reactor lifetime postpones the development of this market. In this context, this study aims at giving an anticipated view of the plant dismantling market by 2030, at deciphering growth levers for the sector actors, and at understanding the sector operation and the business model of operators. Thus, the report presents the main components of the market (key figures, dismantling types, dismantling steps, sector ecosystem, barriers to enter the market, costs, contractual relationships), proposes an analysis of the market and of its perspectives (situation in France, and at the world level, predictive scenario for 2030), and discusses the development axes and demand evolutions (robotization and digitalisation, elaboration of standardised processes, management of wastes produced by nuclear dismantling, internationalisation of French actors). It also proposes an overview of actors in France, and identity sheets for commissioners (EDF, New Areva), contractors (Onet, Vinci, Engie), and other actors (Veolia, Assystem, Ortec, Cybernetix, Oreka Group). The last part proposes synthetic sheets for more than 110 companies of the sector (general information, management and financial performance data under the form of tables and figures) and comparative tables according to 5 key indicators. Data are presented for a period ranging from 2010 to 2016

    Full Text Available The determination of methyl mercury content in green muscle (Mytilus viridis L. that were taken from Pasar Pelelangan Ikan Muara Angke, Jakarta Bay has been carried out. Sampling was taken in November 2005 and March 2006, the samples were bought from the green muscle sellers. The aim of this research is to know the effect of cooking on the content of methyl mercury in green muscle. Samples were homogenized, weighed and washed with aceton and toluene. After washing, the homogenized material was added with HCl solution, extracted with toluene, then the methyl mercury content in toluene extract was analyzed using gas chromatography. The results of this research showed that methyl mercury concentration in raw and cooked green muscle respectively were 0.803 + 0.019 mg/g and 0.443 + 0.035 mg/g (in November 2005 and 0.096 + 0.014 mg/g and 0.079 + 0.016 mg/g (in March 2006 respectively. The methyl mercury content in raw (in November 2005 was higher than in cooked green muscle as permitted concentration in the sea biota by WHO and FAO, it is 0.5 ppm (mg/g, on the other hand the result of the second sampling in March 2006 showed that methyl mercury content in green muscle was lower than permitted concentration. Cooking process of the green muscle decreased methyl mercury content 44.85% (sampling in November 2005 and 17.71% (sampling in March 2006, because methyl mercury that bonded to protein were distributed to boiling water. Methyl mercury content in green muscle after cooking was still lower than the permitted concentration.   Keywords: methyl mercury, green muscle, Mytilus viridis L., Muara Angke

    Full Text Available We study the pricing of American options in an incomplete market in which the dynamics of the underlying risky asset is driven by a jump diffusion process with stochastic volatility. By employing a risk-minimization criterion, we obtain the Radon-Nikodym derivative for the minimal martingale measure and consequently a linear complementarity problem (LCP for American option price. An iterative method is then established to solve the LCP problem for American put option price. Our numerical results show that the model and numerical scheme are robust in capturing the feature of incomplete finance market, particularly the influence of market volatility on the price of American options.

    It is hypothesized that rapeseed lecithins may have different emulsifying and antioxidant properties in delivering fish oil compared to soy lecithin based on previous studies. The results showed that in vitro antioxidant activities of rapeseed lecithins were stronger than those of soy lecithin. Emulsions stabilized by rapeseed based lecithins and DATEM were stable over 3 months at 4 °C, whereas the creaming of emulsions containing soy lecithin started immediately after its preparation. Zeta-potential of rapeseed lecithins was higher than soy lecithin and DATEM, which partially contributed to the emulsion stability. Although the particle sizes of emulsions prepared by rapeseed lecithins increased after 14 days storage, no creaming was observed. Lipid oxidation as indicated by TBARS values suggested that DATEM was the most unfavorable, followed by soy lecithin. It is concluded that rapeseed lecithins are better than soy lecithin and DATEM in terms of emulsion stability and antioxidant capability, respectively. Copyright © 2018 Elsevier Ltd.

  20. Trophic position and metabolic rate predict the long-term decay process of radioactive cesium in fish: a meta-analysis.

    Directory of Open Access Journals (Sweden)

    Hideyuki Doi

    Full Text Available Understanding the long-term behavior of radionuclides in organisms is important for estimating possible associated risks to human beings and ecosystems. As radioactive cesium (¹³⁷Cs can be accumulated in organisms and has a long physical half-life, it is very important to understand its long-term decay in organisms; however, the underlying mechanisms determining the decay process are little known. We performed a meta-analysis to collect published data on the long-term ¹³⁷Cs decay process in fish species to estimate biological (metabolic rate and ecological (trophic position, habitat, and diet type influences on this process. From the linear mixed models, we found that 1 trophic position could predict the day of maximum ¹³⁷Cs activity concentration in fish; and 2 the metabolic rate of the fish species and environmental water temperature could predict ecological half-lives and decay rates for fish species. These findings revealed that ecological and biological traits are important to predict the long-term decay process of ¹³⁷Cs activity concentration in fish.

    Full Text Available Under the impact of climate changes it is increasingly obvious that forestry should rely more strongly on the multi­functional character of the managed resources. In addition to wood, there is a series of non­wood products and services offered by forests. Non­wood forest products and services consist of various fruits of forest trees and shrubs, mushrooms, various objects made of non­wood material, and especially forest social services, such as recreation, tourism, hunting, photo­safari, etc. This paper presents a marketing analysis on the example of the enterprise dealing with the purchase, processing and sale of wild mushrooms and products made of mushrooms. The study applies a modern methodological approach implemented in similar researches.

    Entomophagy has been linked to nutritional, economic, social and ecological benefits. However, scientific studies on the potential safety risks in eating edible insects need to be carried out for legislators, markets and consumers. In this context, the microbiota of edible insects deserves to be deeply investigated. The aim of this study was to elucidate the microbial species occurring in some processed marketed edible insects, namely powdered small crickets, whole dried small crickets (Acheta domesticus), whole dried locusts (Locusta migratoria), and whole dried mealworm larvae (Tenebrio molitor), through culture-dependent (classical microbiological analyses) and -independent methods (pyrosequencing). A great bacterial diversity and variation among insects was seen. Relatively low counts of total mesophilic aerobes, Enterobacteriaceae, lactic acid bacteria, Clostridium perfringens spores, yeasts and moulds in all of the studied insect batches were found. Furthermore, the presence of several gut-associated bacteria, some of which may act as opportunistic pathogens in humans, were found through pyrosequencing. Food spoilage bacteria were also identified, as well as Spiroplasma spp. in mealworm larvae, which has been found to be related to neurodegenerative diseases in animals and humans. Although viable pathogens such as Salmonella spp. and Listeria monocytogenes were not detected, the presence of Listeria spp., Staphylococcus spp., Clostridium spp. and Bacillus spp. (with low abundance) was also found through pyrosequencing. The results of this study contribute to the elucidation of the microbiota associated with edible insects and encourage further studies aimed to evaluate the influence of rearing and processing conditions on that microbiota.

  6. Physical quality of grains subjected to moistening and drying processes for marketing

    Directory of Open Access Journals (Sweden)

    Paulo C. Coradi

    Full Text Available ABSTRACT The aim was to evaluate the physical quality of conventional and transgenic corn grains, through drying and wetting processes for marketing. The experimental design was completely randomized in a factorial scheme (7 x 3 x 2, corresponding to seven drying times (0, 20, 40, 60, 80, 100 and 120 min, three temperatures of the drying air (80, 100 and 120 °C and two hybrids of corn (conventional AG 1051 and transgenic Herculex@ 30S31H. Grain drying was held in convection oven with forced air ventilation while the wetting was done in a B.O.D chamber. The water movement in the grain, the volume and the electrical conductivity were evaluated periodically. The results showed that the transgenic corn grain reduced the negative effects of drying and moistening on the physical quality. The increase in drying air temperature accelerated the physical deterioration of conventional and transgenic corn grains. The increase in water content by the moistening process caused losses in grain physical quality, similar to the drying process, for both the conventional and transgenic corn grains.

    1978-07-01

    A survey of major fish drying areas, storage facilities and dried fish markets in Bangladesh showed that blow fly, house fly and fruit flies are destructive insects infesting fish during the process of drying. Dermestes maculatus, Necrobia rupifes and earwigs were the most predominant insects infesting dried fish during storage. The effect of irradiation on different developmental stages of D. maculatus was investigated. Results on radiation disinfestation of D. maculatus, the most serious pest during storage, showed that a dose of 30 krad and above would be sufficient to control infestation of dried fish. No changes on organoleptic properties of dried mackerel irradiated with doses up to 400 krad could be detected. Polyethylene bags with a thickness of 0.075 mm and above appeared to be suitable for packaging of dried fish

  8. Body size and geographic range do not explain long term variation in fish populations: a Bayesian phylogenetic approach to testing assembly processes in stream fish assemblages.

    Directory of Open Access Journals (Sweden)

    Stephen J Jacquemin

    Full Text Available We combine evolutionary biology and community ecology to test whether two species traits, body size and geographic range, explain long term variation in local scale freshwater stream fish assemblages. Body size and geographic range are expected to influence several aspects of fish ecology, via relationships with niche breadth, dispersal, and abundance. These traits are expected to scale inversely with niche breadth or current abundance, and to scale directly with dispersal potential. However, their utility to explain long term temporal patterns in local scale abundance is not known. Comparative methods employing an existing molecular phylogeny were used to incorporate evolutionary relatedness in a test for covariation of body size and geographic range with long term (1983 - 2010 local scale population variation of fishes in West Fork White River (Indiana, USA. The Bayesian model incorporating phylogenetic uncertainty and correlated predictors indicated that neither body size nor geographic range explained significant variation in population fluctuations over a 28 year period. Phylogenetic signal data indicated that body size and geographic range were less similar among taxa than expected if trait evolution followed a purely random walk. We interpret this as evidence that local scale population variation may be influenced less by species-level traits such as body size or geographic range, and instead may be influenced more strongly by a taxon's local scale habitat and biotic assemblages.

  9. Fish allergy: in review.

    Sharp, Michael F; Lopata, Andreas L

    2014-06-01

    Globally, the rising consumption of fish and its derivatives, due to its nutritional value and divergence of international cuisines, has led to an increase in reports of adverse reactions to fish. Reactions to fish are not only mediated by the immune system causing allergies, but are often caused by various toxins and parasites including ciguatera and Anisakis. Allergic reactions to fish can be serious and life threatening and children usually do not outgrow this type of food allergy. The route of exposure is not only restricted to ingestion but include manual handling and inhalation of cooking vapors in the domestic and occupational environment. Prevalence rates of self-reported fish allergy range from 0.2 to 2.29 % in the general population, but can reach up to 8 % among fish processing workers. Fish allergy seems to vary with geographical eating habits, type of fish processing, and fish species exposure. The major fish allergen characterized is parvalbumin in addition to several less well-known allergens. This contemporary review discusses interesting and new findings in the area of fish allergy including demographics, novel allergens identified, immunological mechanisms of sensitization, and innovative approaches in diagnosing and managing this life-long disease.

    Contamination of a popular fermented fish dish, pla-som, by Opisthorchis viverrini metacercariae (OVMC) is a possible cause of carcinogenic liver fluke infection in Thailand. Affected individuals are at risk of bile duct cancer, which is a major health problem for people in the Greater Mekong Subregion. In order to investigate concerns about food safety, we studied the effects of fermentation time and low temperature on the viability and infectivity of OVMC during the pla-som production process. Pla-som was prepared at room temperature for up to 1 week in duplicate experiments using cyprinid freshwater fish obtained from an O. viverrini-endemic area. OVMC were then isolated and identified under a stereomicroscope. Complete and viable OVMC were found on days 1-4 of fermentation, while their morphology was degenerated thereafter. After OVMC were fed to hamsters, the percentage of the worm recovery after 1 to 2 months of infection was 52%, 44.7%, 11.3% and 1% for days 1, 2, 3 and 4, respectively. In order to measure the effect of low temperature on OVMC, fish were kept in a refrigerator (4 °C) for up to five days and then subsequently fermented for three days. In fish stored in a refrigerator for 1 and 2 days, viable OVMC were clearly observed and were able to infect hamsters, a worm-recovery percentage of 3.3% and 12.7%, respectively. By contrast, in pla-som prepared from fish stored for 3 to 5 days, OVMC were degenerated and could not infect the host. In conclusion, pla-som fermentation for more than four days and refrigerating fish for three days before pla-som processing can prevent O. viverrini infection. This study may increase awareness of fermented-fish dish preparation to prevent liver fluke infection. Copyright © 2015 Elsevier B.V. All rights reserved.

  12. Market Opportunity of Some Aluminium Silicon Alloys Materials through Changing the Casting Process

    2012-08-01

    Full Text Available Fatigue is considered to be the most common mechanism by which engineering components fail, and it accounts for at least 90% of all service failures attributed to mechanical causes. Mechanical properties (tensile strength, tensile strain, Young modulus, etc as well as fatigue properties (fatigue life are very dependent on casting method. The most direct effects of casting techniques are on the metallurgical microstructure that bounds the mechanical properties. One of the important variables affected by the casting technique is the cooling rate which is well known to strongly restrict the microstructure. In the present research has been done a comparison of fatigue properties of two aluminum silicon alloys obtained by two casting techniques. It was observed that the fatigue life is increasing with 24% for Al12Si and 31% for AL18Si by using centrifugal casting process instead of gravity casting. This increasing in fatigue life means that a component tailored from materials obtained by centrifugal casting will stay longer in service. It was made an estimation of the time required to recover the costs of technology in order to use the centrifuge process that will allow to obtain materials with improved properties. The amortization can be achieved by using two different marketing techniques: through the release of the product at the old price and with much longer life of the component which means "same price - longer life", or increasing price, by highlighting new product performance which means "higher price - higher properties".

  13. Gas processing developments in the U.S. and their relevance to the Canadian market

    Williams, K.L.

    1999-01-01

    The underlying issues which have been responsible for the changes in the natural gas processing industry in the U.S. for the past 10 years are discussed. The objective of this paper is compare trends in the U.S. with the evolving midstream industry in western Canada and to emphasize the striking similarities. The positive impacts that price regulation and deregulation had on midstream companies are described. Another boost to midstream function was provided when FERC issued approving orders granting pipeline companies the ability to spin-down their gathering and processing assets into non-federally regulated companies. The need for exploration and production companies to sustain capital spending, focus on core business activities and streamline the balance sheet to maximize value in the stock market, have driven many recent US midstream transactions. The formation of independent midstream start-up companies, capital deployment into midstream assets by Canadian transmission companies and interest shown by US midstream companies in Canadian midstream assets suggests that a similar evolution is under way in Canada. Formation of a Canadian midstream industry is well underway, and should fully materialize in the next decade. Major US midstream transactions over the past five years are briefly summarized to illustrate the growing confidence in independent midstream companies to provide reliable and cost-effective midstream services

    This study evaluated the decontamination of Pangasius fillets in chlorine or peracetic acid treated wash water. First, the decontamination efficacy of the washing step with chlorinated water applied by a Vietnamese processing company during trimming of Pangasius fillets was evaluated and used as the basis for the experiments performed on a laboratory scale. As chlorine was only added at the beginning of the batch and used continuously without renewal for 239min; a rapid increase of the bacterial counts and a fast decrease of chlorine in the wash water were found. This could be explained by the rapid accumulation of organic matter (ca. 400mg O2/L of COD after only 24min). Secondly, for the experiments performed on a laboratory scale, a single batch approach (one batch of wash water for treating a fillet) was used. Chlorine and PAA were evaluated at 10, 20, 50 and 150ppm at contact times of 10, 20 and 240s. Washing with chlorine and PAA wash water resulted in a reduction of Escherichia coli on Pangasius fish which ranged from 0-1.0 and 0.4-1.4logCFU/g, respectively while less to no reduction of total psychrotrophic counts, lactic acid bacteria and coliforms on Pangasius fish was observed. However, in comparison to PAA, chlorine was lost rapidly. As an example, 53-83% of chlorine and 15-17% of PAA were lost after washing for 40s (COD=238.2±66.3mg O2/L). Peracetic acid can therefore be an alternative sanitizer. However, its higher cost will have to be taken into consideration. Where (cheaper) chlorine is used, the processors have to pay close attention to the residual chlorine level, pH and COD level during treatment for optimal efficacy. Copyright © 2015.

    To elucidate radioecological concentration processes of Am by aquatic organisms, uptake and retention of Am-241 by fingerlings of rainbow trout were investigated under laboratory conditions using natural river water and with aeration. The results were compared with those of some other radionuclides such as Co-60, Ru-106, I-131, Cs-137 and Ce-144. The fractionation of the radionuclides in rearing waters using 0.45μm membrane filters showed that about 90% of Am as well as Ce were retained on the filters at apparent equilibrium states, while about 20% for RuNO-nitrato and less than 10% for nitro, oxygen-bridged binuclear Ru-complexes, Co, I and Cs, respectively. The pattern of whole-body uptake of Am was similar to that of Ce and the radioactivities in fish reached apparent equilibrium in about 10 days, whereas several days for the other radionuclides. The average concentration factor for Am was 1.8 and 6.5 for Co, 0.8 for Ru-chloro, 1.7 for Ru-nitro, 3.5 for Ru-nitrato, 0.9 for Ru-binuclear complexes, 1.9 for I, 1.3 for Cs, 1.8 for Ce, respectively. The tissue uptakes of Am as well as the other radionuclides except for I were the highest in visceral mass including digestive tracts and followed by gills. The alpha-track autoradiograms of frozen section of fish also demonstrated the occurrences of agglutinated Am in the digestive tracts. The initial whole-body retention of Am was about 85% in 10 days and thereafter gradually decreased. The elimination of Am from the tissues was the highest in gills and only about 9% of whole-body retention was observed in 20 days, whereas about 63% in visceral mass including digestive tracts

This research was aimed to assess and analyzes: the processing of smoked mackerel tuna based on local wisdom, public perception towards the processing of smoked mackerel tuna, and the quality of smoked mackerel tuna. The research carried out on January to April 2014, in Jangkar Village, Situbondo regency. The study included depth interview from key persons with questionnaire and organoleptic test. The public perception on smoked mackerel tuna was taken by questionnaire from 85 respondents, whereas the quality of smoked mackerel tuna was analyzed with laboratory proximate test. Result of this research showed that smoked mackerel tuna processing used traditional smoking instrument and fuel material. The smoking stall used several banana midrib stem above the furnace that made of cement and bricks, while the fuel use coconut coir which created the typical flavors of the smoked mackerel tuna. The average organoleptic value of the smoked mackerel tuna appearance is 7.89 (intact, clean, brown, very shiny specific type, flavors of 8.24 (less fragrant, smoked enough, without additional disturbing odor, taste of 8.41 (delicious, savory, texture of 7.40 (solid, compact, fairly dry, tight inter-flesh tissue, and colour of 7.20 (attractive, specific, shiny brown colour type. Public perception showed that the community knowledge on smoked mackerel tuna processing is good, creates good flavors of smoked mackerel tuna and favored by the community, thus also encourage the community to support the conservation of this traditional smoked processing.

    Full Text Available The urgency of the research. Before the modern person at different stages of reproduction of the human capital, there are many calls and risks that need to be considered and also to adapt to consequences of their action. Target setting. Use of marketing tools is rather a perspective direction of improvement of processes of the human capital reproduction. However, improvement of these processes is promoted by only socially responsible marketing. Uninvestigated parts of general matters defining. Almost unexplored are questions of use of marketing tools in the realization of processes of reproduction of the human capital. The purpose of the paper is to study the use of marketing tools for more effective implementation of reproduction processes of human capital at different stages. The issue of reproduction of human capital is considered in such areas: education, health, and social and labour sphere. Methodology. The paper is based on a critical analysis of scientific researches in the sphere of socially responsible marketing and processes of reproduction of human capital. These issues are researched by Blagov Yu.E., Carroll A., Hrishnova O.A., Kotler P., Lantos J., Lambin J., Libanova E.M., Mishchuk H.Yu., and others. Results. Issues of the human capital reproduction are considered in the following spheres: education, healthcare, and social and labour sphere. It is defined that in modern conditions, social responsibility has to become a basis for the creation of all system of the public relations and cover all stages of reproduction of the human capital. Socially irresponsible marketing leads to the formation, accumulation, and distribution of the fictitious human capital and other its unproductive forms. Practical implications.

  3. Enzymes in Fermented Fish.

    Science.gov (United States)

    Giyatmi; Irianto, H E

    Fermented fish products are very popular particularly in Southeast Asian countries. These products have unique characteristics, especially in terms of aroma, flavor, and texture developing during fermentation process. Proteolytic enzymes have a main role in hydrolyzing protein into simpler compounds. Fermentation process of fish relies both on naturally occurring enzymes (in the muscle or the intestinal tract) as well as bacteria. Fermented fish products processed using the whole fish show a different characteristic compared to those prepared from headed and gutted fish. Endogenous enzymes like trypsin, chymotrypsin, elastase, and aminopeptidase are the most involved in the fermentation process. Muscle tissue enzymes like cathepsins, peptidases, transaminases, amidases, amino acid decarboxylases, glutamic dehydrogenases, and related enzymes may also play a role in fish fermentation. Due to the decreased bacterial number during fermentation, contribution of microbial enzymes to proteolysis may be expected prior to salting of fish. Commercial enzymes are supplemented during processing for specific purposes, such as quality improvement and process acceleration. In the case of fish sauce, efforts to accelerate fermentation process and to improve product quality have been studied by addition of enzymes such as papain, bromelain, trypsin, pepsin, and chymotrypsin. © 2017 Elsevier Inc.

    This work focused in the evaluation of Oreochromis niloticus fish scales (FS) as biosorbent material in the removal of Zn from a synthetic effluent based on automotive battery industry effluent and, further, a hybrid neutralization/biosorption process, aiming at a high-quality treated effluent, by a cooperative use of dolomite and FS. For this, a physicochemical and morphological characterization (i.e. SEM-EDX, FTIR, XRD, and TXRF) was performed, which helped to clarify a great heterogeneity of active sites (phosphate, carbonate, amide, and hydroxyl) on the biosorbent; also the inorganic constituents (apatites) leaching from the FS was identified. Biosorption results pointed out to a pH-dependent process due to changes in the functional group's anionic character (i.e. electrostatic interactions), where an initial pH = 3 favored the Zn uptake. Kinetic and equilibrium studies confirmed the heterogeneous surface and cooperative sorption, wherein experimental data were described by Generalized Elovich kinetic model and the favorable isotherm profile by Langmuir-Freundlich isotherm ([Formula: see text] = 15.38 mg g -1 and [Formula: see text]). Speciation diagram of Zn species along with the leached species demonstrated that, for the studied pH range, the biosorption was the most likely phenomena rather than precipitation. Finally, the hybrid neutralization/biosorption process showed great potential since both the Zn concentration levels and the pH reached the legislation standards (C Zn  = 4 mg L -1 ; pH = 5). Hence, based on the characterization and biosorption results, a comprehensive evaluation of the involved mechanisms in such complex system helped to verify the prospective of FS biosorbent for the Zn treatment from solution, in both individual and hybrid processes.

  8. THE EFFECTS OF BANKRUPTCY ON THE PREDICTABILITY OF PRICE FORMATION PROCESSES ON WARSAW’S STOCK MARKET

    Full Text Available In this study we investigate how bankruptcy affects the market behaviour of prices of stocks on Warsaw’s Stock Exchange. As the behaviour of prices can be seen in a myriad of ways, we investigate a particular aspect of this behaviour, namely the predictability of these price formation processes. We approximate their predictability as the structural complexity of logarithmic returns. This method of analysing predictability of price formation processes using information theory follows closely the mathematical definition of predictability, and is equal to the degree to which redundancy is present in the time series describing stock returns. We use Shannon’s entropy rate (approximating Kolmogorov-Sinai entropy to measure this redundancy, and estimate it using the Lempel-Ziv algorithm, computing it with a running window approach over the entire price history of 50 companies listed on the Warsaw market which have gone bankrupt in the last few years. This enables us not only to compare the differences between predictability of price formation processes before and after their filing for bankruptcy, but also to compare the changes in predictability over time, as well as divided into different categories of companies and bankruptcies. There exists a large body of research analysing the efficiency of the whole market and the predictability of price changes enlarge, but only a few detailed studies analysing the influence of external stimulion the efficiency of price formation processes. This study fills this gap in the knowledge of financial markets, and their response to extreme external events.

  11. Price Determinants of the Tendering Process for Pharmaceuticals in the Cyprus Market.

    Petrou, Panagiotis; Talias, Michael A

    2015-09-01

    Tendering has been a promising approach for procuring pharmaceuticals. Significant price reductions have been well documented by several authors. To our knowledge, there are limited data detailing the impact of variables in the tendering process. In this article, our objective was to evaluate the impact of potentially exploratory variables, which included innovation status, total value and volume of sales of each product, health care setting administration (hospital/outpatient), patent status (branded/generic), tendering type, and wholesale price, on price reduction in the tendering process. Financial data of public sector sales during 2011 were analyzed. On the basis of these data, we selected 178 medicines with corresponding sales of €49 million, out of a total market value of €104 million. Medicines were selected according to volume, value, and therapeutic value across all therapeutic areas. We performed a beta regression for the assessment of impact of variables and applied the same methodology to different subgroups. The generic status of medicines is statistically significantly associated with a higher price reduction. Tendering type by alternative, high wholesale prices, and high volume are robust estimators for price reduction. Innovation status does not have any effect on price reduction. Outpatient medicines reach lower prices as compared with hospital medicines. A rather unexpected finding is the negative correlation of high sales value with price reduction. These findings will lead to better understanding of the tendering framework, enabling us to further evolve its operational capacity, aiming to generate more savings. Moreover, our study indicates areas in which a more optimized approach is needed. Copyright © 2015 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

  12. Segmentation algorithm for non-stationary compound Poisson processes. With an application to inventory time series of market members in a financial market

    Science.gov (United States)

    Tóth, B.; Lillo, F.; Farmer, J. D.

    2010-11-01

    We introduce an algorithm for the segmentation of a class of regime switching processes. The segmentation algorithm is a non parametric statistical method able to identify the regimes (patches) of a time series. The process is composed of consecutive patches of variable length. In each patch the process is described by a stationary compound Poisson process, i.e. a Poisson process where each count is associated with a fluctuating signal. The parameters of the process are different in each patch and therefore the time series is non-stationary. Our method is a generalization of the algorithm introduced by Bernaola-Galván, et al. [Phys. Rev. Lett. 87, 168105 (2001)]. We show that the new algorithm outperforms the original one for regime switching models of compound Poisson processes. As an application we use the algorithm to segment the time series of the inventory of market members of the London Stock Exchange and we observe that our method finds almost three times more patches than the original one.

    NCE Smart Energy Markets conducted in the period 2009 - 2010 a foresight process in which it was conducted a preliminary meeting, a kick-off meeting, four major collections and a 'recovery meeting' way for players who would enter the process. As a result, they decided to continue a joint process management meetings under the name of the cluster with new collections 2010 - 2011 with the same external process manager. VRI Oestfold; Oestfold Research helped with follow-up evaluation of the process and presented in this report findings from the evaluation of the process. The purpose of the evaluation was, among other things, to contribute to a good process flow, documentation of experiences and achievements and contributions to better understanding and discussion about the direction and emphasis on the way. The evaluation aimed to answer the following three questions: Are the expected results achieved? Is the process complete successfully?Is foresight appropriate instrument in the given situation?The findings indicate that participants perceive that they are on course to reach the goals that are related to the community; common cluster strategy for growth and renewal, carving out the correct goals for the future, the process for getting into a committed relationship, and develop an innovative environment that can stay ahead of the market. At the same time they perceive that they are not close to having achieved the one goal that is directly related to the individual company - to contribute to the individual company's strategy will be more successful. Process management is perceived as a distinct and developing well underway, while project management is perceived as not quite so obvious, but in a better development. When we look at the core businesses consisting of few active businesses and some of the original have reduced their participation, while a number new have come to the last two workshops. It also appears that there is a potential to increase

    2013-06-01

    The current study describes the frequency of use of different forms of nutrition marketing in Canada and the nutrients and conditions that are the focus of nutrition marketing messages. Prepackaged foods with a Nutrition Facts table (N = 10,487) were collected between March 2010 and April 2011 from outlets of the 3 largest grocery chains in Canada and 1 major western Canadian grocery retailer. The nutrition marketing information collected included nutrient content claims, disease risk reduction claims, and front-of-pack nutrition rating systems (FOPS). We found that nutrition marketing was present on 48.1% of Canadian food packages, with nutrient content claims being the most common information (45.5%), followed by FOPS on 18.9% of packages. Disease risk reduction claims were made least frequently (1.7%). The marketing messages used most often related to total fat and trans fat (15.6% and 15.5% of nutrient content claims, respectively). Limiting total and trans fats is a current public health priority, as recommended by Health Canada and the World Health Organization. However, other nutrients that are also recommended to be limited, including saturated fats, sodium, and added sugars, were not nearly as prominent on food labels. Thus, greater emphasis should be placed by the food industry on these other important nutrients. Repeated data collection in the coming years will allow us to track longitudinal changes in nutrition marketing messages over time as food marketing, public health, and consumer priorities evolve.

    1998-01-01

    Residues of 14 C-DDT in stored dried fish was determined under ambient conditions for a 6 month period. Immediately after treatment, about 40% of the applied DDT was eliminated from surface of the dried fish with water washing. However, such removal was reduced to about 26% on storage for 6 months. Boiling of dried fish in water resulted in further removal of about 16% residues. In boiled dried fish, about 14% residues might remain and this could be removed by Soxhlet extraction. Surface extraction with hexane yielded about 80% of the residues immediately after treatment and the extractable residues decreased to about half the initial value of 6 months' storage. Dried fish residues, on surface extraction with water or hexane, when subjected to exhaustive Soxhlet extraction with methanol was found to result in further recovery of about 39-49% and 17-32%, respectively. Bound DDT residues were found to be about 5% in water washed dried fish samples and about 1.5% in case of hexane-extracted samples. Degradation of parent DDT to DDE and DDD was found. Maximum values of 16.58% DDE and 21.6% DDD were found in dried fish stored for 6 months. (author)

    A convenience ready-to-reconstitute cutlet mix containing 30% fish protein powder was developed to improve the nutritional quality of the product. Consumer survey was based on the home use test (HUT) method. The acceptance of the fish cutlet mix (FCM) was studied using a 9-point hedonic scale ranging from 1 (extremely dislike) to 9 (extremely like). Product's characteristics and stability were studied during 6 months of storage at 27 ± 2 °C. The FCM packed in a polyethylene bag and cardboard box was stable during the storage period. There were no changes in colour, moisture gain and water activity, and TBARS values remained low. The FCM was accepted by the consumers in the study (n = 85). The average liking was high (7.5 ± 1.3) and it was influenced by frequency of fish and chicken consumption, educational level and household size. People who ate fish once a week liked the product more than other consumers. Also those with higher educational level and bigger household size. The results in this paper are important information for companies planning to develop ready-to-eat products fortified with fish proteins. The products could be means of increasing fish consumption in countries/areas where there is no tradition of consuming fresh or frozen fish.

    Full Text Available Otolith formation involves rhythmic variations in the deposition and size of organic matrix framework and carbonate crystals, resulting in the formation of macroscopic translucent and opaque rings and microscopic zonations (growth increments (Morales Nin, 2000. As in most biominerals, the otolith matrix forms only 2-3 % of its weight, but it is admitted that it has a considerable importance in the otolith crystallization processes of nucleation, growth, orientation and growth control. The goal of this study is to characterize the matrix protein composition in the otoliths of Triglidae (Scorpaeniformes as a first step to understand molecular mechanisms of otolith formation according to biology and ecology of the species. In particular 500 sagittal otoliths from six gurnard species were analysed: Chelidonichthys cuculus, C. lucerna, Eutrigla gurnardus, Lepidotrigla cavillone, L. dieuzeidei and Trigloporus lastoviza. Protein contents were estimated by Bradford method and the urea 8 M extracts were loaded into a polyacrylamide gel, separated by SDS page and detected by Silver staining (Sigma followed the protocol of Borelli et al. (2001 with some modifications regarding protein precipitation that was enhanced by using TCA, trichloroacetic acid, 100% w/v. The urea soluble fractions revealed a unique large band around 50-55 kDa. Another common clear band was visible at the top of the separating gel (proteins >300/350 kDa unable to enter into the pores of polyacrylamide gels (12%. The complexity of the protein mixtures was investigated by 2-D electrophoresis (Gel TGX 4-20%; proteins were separated on the basis of both isoelectric point (pI and molecular size. A common protein pattern of 50-75 kDa were found in all gurnards showing a similar composition of organic matter even if the 2-D maps of otolith samples showed specie-specific variation in acid protein fractions in all the pairwise comparison. This result confirmed that the amino acid composition

    This study was conducted to determine the concentration of total mercury in the edible portion of 46 species of marine fish (n = 297) collected from selected major fish landing ports and wholesale markets throughout Peninsular Malaysia. Samples were collected in June to December 2009. Prior to analysis, the fish samples were processed which consisted of drying at 65 °C until a constant weight was attained; then, it was grounded and digested by a microwave digestion system. The analytical determination was carried out by using a mercury analysis system. Total mercury concentration among fish species was examined. The results showed that mercury concentrations were found significantly higher (p mercury concentrations were also higher in carnivorous fish especially in the species with more predatory feeding habits. Besides, the family group of Latidae (0.537 ± 0.267 mg/kg in dried weight), Dasyatidae (0.492 ± 0.740 mg/kg in dried weight), and Lutjanidae (0.465 ± 0.566 mg/kg in dried weight) showed significantly (p mercury levels compared to other groups. Fish collected from Port Klang (0.563 ± 0.509 mg/kg in dry weight), Kuala Besar (0.521 ± 0.415 mg/kg in dry weight), and Pandan (0.380 ± 0.481 mg/kg in dry weight) were significantly higher (p = 0.014) in mercury concentrations when compared to fish from other sampling locations. Total mercury levels were significantly higher (p 20 cm) and were positively related with fish size (length and weight) in all fish samples. Despite the results, the level of mercury in marine fish did not exceed the permitted levels of Malaysian and JECFA guideline values at 0.5 mg/kg methylmercury in fish.

    Full Text Available ABSTRACT: The consumption of fish by the Brazilian population is increasing. However, fish and seafood are highly perishable and can be contaminated with several microorganisms. In addition, the possibility of biofilm formation is a greater cause for concern. In this study, biofilm formation was evaluated in single- and multispecies cultures at 25°C for incubation periods of 0, 4, 8, 24, and 48h in stainless steel coupons (size, 1.0×1.0cm immersed in tryptic soy broth. The characteristics of the formed biofilms after sanitizing by immersing the coupons in 200ppm sodium hypochlorite solution for 10min were also evaluated under the same experimental conditions but with some modifications. Biofilm structure was evaluated using scanning electron microscopy. Analysis of single-species biofilms indicated that all bacterial strains formed biofilms at different intervals without any statistically significant difference. However, comparison of the growth of single- and multispecies cultures indicated a significantly higher biofilm formation by the pure cultures. In multispecies biofilms, compared with the other microorganisms, growth of Salmonella spp. was significantly lower for all tested incubation periods; whereas, of Staphylococcus aureus was significantly higher than that of E. coli until 8h of incubation; the differences in growth were not significantly different after this incubation period. Sanitizing with sodium hypochlorite was effective because no cell growth was observed in the coupons that were treated with 200ppm sodium hypochlorite for 10min. This study demonstrated the ability of isolated microorganisms to form biofilms, reinforcing the need for food handling establishments to adopt good manufacturing practices, developing adequate protocols for cleaning and disinfecting surfaces and equipment used in food production, maintaining and replacing equipment when necessary.

    Studies were made on different types of packaging materials used for packing dried fish in the Philippines with a view to finding a suitable packaging material for irradiated dried fish. Among these packaging materials (polyethylene, cello/polyethylene, polyester/polyethylene, Kraft paper, polypropylene and interwoven polypropylene sacks), polyester/polyethylene laminate was the most resistant material against penetration by Dermestes carnivorous. No insect damage occurred on the dried fish packed in interwoven polypropylene lined with polyester/polyethylene laminate. The cost per sack of such packaging material having a capacity of 50-80 kg is US$ 0.50. The sack lined with polyester/polyethylene proved to be durable for surface transportation from Bacolod City to Manila (approx. 360 miles). Radiation treatment at 225 krad was effective against bacterial contamination but not effective in inhibiting mould growth. Raw fish soaked in 25% salt for 2 hours before drying obtained the highest scores in most of the organoleptic attributes. Dried fish which contains approx. 50% moisture and residual salt content of 6% would spoil within 2 weeks at ambient conditions. Treatment with 2% potassium sorbate and 225 krad showed that samples can be stored under commercial practice and at ambient conditions for up to 62 days

    Full Text Available The research of consumer behavior for the purpose of its formation and effective impact on it becoming a key element of the marketing activities of modern enterprises, working on a wide variety of goods and services markets. Currently, there is a tendency of convergence of cosmetics to pharmaceuticals and a new product appears which combines the quality of cosmetics and pharmaceuticals, and called "cosmeceuticals" or pharmaceutical cosmetics. When providing services in the market of pharmaceutical cosmetics the knowledge of regularities and factors of consumer behavior, and ability to adapt to its changes is of great importance. Now in the conditions of dynamically developing market environment, the system research of factors of consumer behavior in the market of pharmaceutical cosmetics is necessary, including the problem resolution of its identification, forecasting of their dynamics and the impact directed to them is required. At the same time, there are no reliable theoretical and methodical bases for such decisions. The insufficient readiness of methodical tools for identification and assessment of factors of consumer behavior interferes with improvement of quality of the rendered services in the sphere of medical services in case of sale of pharmaceutical cosmetics. Besides, one of important components of modern system of complex service marketing is automation of means of its implementation that assumes the maximum automation of process of conducting personal selling by means of which influence of a human factor is minimized and working hours are significantly saved. However, its successful implementation requires expansion of methodical approaches to system of an efficiency evaluation in the sphere of medical services in relation to the market of retail trade by pharmaceutical cosmetics.

  8. Economic efficiency of countries' clinical review processes and competitiveness on the market of human experimentation.

    2013-01-01

    Clinical research is a specific phase of pharmaceutical industry's production process in which companies test candidate drugs on patients to collect clinical evidence about safety and effectiveness. Information is essential to obtain manufacturing authorization from the national drug agency and, in this way, make profits on the market. Considering this activity, however, the public stakeholder has to face a conflict of interests. On the one side, there is society's necessity to make advances in medicine and, of course, to promote pharmaceutical companies' investments in this specific phase (new generation). On the other side, there is the duty to protect patients involved in these experimental treatments (old generation). To abide by this moral duty, a protection system was developed through the years, based on two legal institutions: informed consent and institutional review board. How should an efficient protection system that would take human experimentation into account be shaped? Would it be possible for the national protection system of patients' rights to affect the choice of whether to develop a clinical trial in a given country or not? Looking at Europe and considering a protection system that is shaped around institutional review boards, this article is an empirical work that tries to give answers to these open questions. It shows how a protection system that can minimize the time necessary to start a trial can positively affect pharmaceutical clinical research, that is, the choice of pharmaceutical companies to start innovative medical treatments in a given country.

  10. Inferring processes from spatial patterns: the role of directional and non-directional forces in shaping fish larvae distribution in a freshwater lake system.

    Directory of Open Access Journals (Sweden)

    Andrea Bertolo

    Full Text Available Larval dispersal is a crucial factor for fish recruitment. For fishes with relatively small-bodied larvae, drift has the potential to play a more important role than active habitat selection in determining larval dispersal; therefore, we expect small-bodied fish larvae to be poorly associated with habitat characteristics. To test this hypothesis, we used as model yellow perch (Perca flavescens, whose larvae are among the smallest among freshwater temperate fishes. Thus, we analysed the habitat association of yellow perch larvae at multiple spatial scales in a large shallow fluvial lake by explicitly modelling directional (e.g. due to water currents and non-directional (e.g. due to aggregation spatial patterns. This allowed us to indirectly assess the relative roles of drift (directional process and potential habitat choice on larval dispersal. Our results give weak support to the drift hypothesis, whereas yellow perch show a strong habitat association at unexpectedly small sizes, when compared to other systems. We found consistent non-directional patterns in larvae distributions at both broad and medium spatial scales but only few significant directional components. The environmental variables alone (e.g. vegetation generally explained a significant and biologically relevant fraction of the variation in fish larvae distribution data. These results suggest that (i drift plays a minor role in this shallow system, (ii larvae display spatial patterns that only partially covary with environmental variables, and (iii larvae are associated to specific habitats. By suggesting that habitat association potentially includes an active choice component for yellow perch larvae, our results shed new light on the ecology of freshwater fish larvae and should help in building more realistic recruitment models.

    Full Text Available Fish species identification and automated fish freshness assessment play important roles in fishery industry applications. This paper describes a method based on support vector machines (SVMs to improve the performance of fish identification systems. The result is used for the assessment of fish freshness using artificial neural network (ANN. Identification of the fish species involves processing of the images of fish. The most efficient features were extracted and combined with the down-sampled version of the images to create a 1D input vector. Max-Win algorithm applied to the SVM-based classifiers has enhanced the reliability of sorting to 96.46%. The realisation of Cyranose 320 Electronic nose (E-nose, in order to evaluate the fish freshness in real-time, is experimented. Intelligent processing of the sensor patterns involves the use of a dedicated ANN for each species under study. The best estimation of freshness was provided by the most sensitive sensors. Data was collected from four selected species of fishes over a period of ten days. It was concluded that the performance can be increased using individual trained ANN for each specie. The proposed system has been successful in identifying the number of days after catching the fish with an accuracy of up to 91%.

    The European anchovy (Engraulis encrasicolus), one of the most important pelagic fish resources in the Mediterranean Sea, is frequently infected by anisakid larvae. Food Business Operators (FBOs) should use appropriate sampling plans and analytical methods to avoid commercialization of massively infected batches and reduce the risk of transmission of viable zoonotic larvae. In this study, performed at FishLab (Department of Veterinary Sciences of the University of Pisa) during 2016, an official sampling plan was associated with a digestion protocol for the inspection of anchovies. Considering that anisakid larvae are usually located in the fish visceral cavity and in the adjacent muscles (VM), this part was analyzed. In particular, we assessed the reliability of the digestion of a subsample of 150g (±30g) of VM, randomly collected from 29 specimens, in estimating the marketability of the anchovies' batch. Fifty-seven samples of 29 anchovies were collected. Each anchovy was sectioned to separate VM. All the subsamples were digested, and visible larvae counted. A high correlation between the number of larvae in VM regions and in the total batch was observed, indicating a very significant contribution of the VM region on total number of parasites. The Mean Abundance (MA) was used to assess the batch marketability according to a threshold calculated on the basis of the maximum number of nematodes tolerated per sample. Considering that the MA can be calculated only when the number of examined specimens is known, the number of visible Larvae per gram of tissue (LpG) was calculated on 150g (±30g) of VM subsamples. A LpG marketability threshold was calculated dividing the maximum number of tolerated nematodes by the average weight of a sample of 29 anchovies calculated considering data available in literature. To evaluate the diagnostic performance of the LpG threshold, the marketability of 57 batches assessed on the basis of the MA threshold was assumed as the gold

    2016-01-01

    Fish is one of the main elicitors for food allergies. For a long time, the clinical picture of fish allergy was reduced to the following features. First, fish-allergic patients suffer from a high IgE cross-reactivity among fishes so that they have to avoid all species. Second, clinically relevant...... symptoms are linked to the presence of IgE-antibodies recognizing parvalbumin, the fish panallergen. This view was challenged by results from recent studies as follows. 1. Allergic reactions which are limited to single or several fish species (mono-or oligosensitisations) apply not only to single cases...... but patients with this phenotype constitute an important sub-group among fish-allergic individuals. 2. Newly identified fish allergens, enolases, aldolases, and fish gelatin, are of high relevance as the majority of the fish-allergic individuals seem to develop specific IgE against these proteins. The present...

    The objective was: 1) to characterize the effect of marketing group on fresh and cured ham quality, and 2) to determine which fresh ham traits correlated to cured ham quality traits. Pigs raised in 8 barns representing 2 seasons (hot and cold) and 2 production focuses (lean and quality) were used. Three groups were marketed from each barn. A total of 7,684 carcasses were used for data collection at the abattoir. Every tenth carcass was noted as a select carcass for in-depth ham quality analyses. Leg primal weight and instrumental color were measured on 100% of the population. On the select 10% of the population, hams were fabricated into sub-primal pieces, and 3-piece hams were manufactured to evaluate cured ham quality and processing yield. Data were analyzed as a split-plot design in the MIXED procedure of SAS with production focus as the whole-plot factor, and marketing group as the split-plot factor. Pearson correlation coefficients between fresh and cured ham traits were computed. There were no differences ( ≥ 0.15) in instrumental color or ultimate pH ( ≥ 0.14) among fresh ham muscles from any marketing group. The only exception was the semimembranosus of marketing group 2 was lighter than marketing group 1 ( = 0.03) and the dark portion of the semitendinosus muscle from group 1 was lighter than from group 3 ( = 0.01). There were no differences ( ≥ 0.33) in ultimate pH of fresh ham muscles between production focuses, but several muscles from quality focus pigs were lighter in color than ham muscles from lean focus pigs. The lack of differences in fresh ham quality lead to few differences in cured ham quality. Cured hams from the quality focus pigs had greater lipid content ( marketing group 1 and 2 were 1.52 units lighter than hams from marketing group 3 ( 0.01). Overall, marketing group did not impact ham quality. Fresh ham quality was not strongly related to cured ham quality. Some correlations were present between fresh and cured ham traits, but

    The current wave of privatization and deregulation of the electric energy market has created new challenges. This is true in many parts of the world. Power companies are cast in the role of 'energy service companies' instead of 'energy suppliers'. The increasing competition between market actors and the requirements for improved overall security, economy and quality of service is accelerating the demand for more accurate and up-to-date information. Information becomes a strategic resource. To be able to constitute its full potential to users all over the power company the keyword becomes integration. Technical, business and administrative applications need to be viewed in a new, corporate wide perspective. The revised IT-strategy therefore becomes a tool for positioning the company in the competitive market. 8 refs, 4 figs

  17. Stochastic processes in the social sciences: Markets, prices and wealth distributions

    Science.gov (United States)

    Romero, Natalia E.

    The present work uses statistical mechanics tools to investigate the dynamics of markets, prices, trades and wealth distribution. We studied the evolution of market dynamics in different stages of historical development by analyzing commodity prices from two distinct periods ancient Babylon, and medieval and early modern England. We find that the first-digit distributions of both Babylon and England commodity prices follow Benfords law, indicating that the data represent empirical observations typically arising from a free market. Further, we find that the normalized prices of both Babylon and England agricultural commodities are characterized by stretched exponential distributions, and exhibit persistent correlations of a power law type over long periods of up to several centuries, in contrast to contemporary markets. Our findings suggest that similar market interactions may underlie the dynamics of ancient agricultural commodity prices, and that these interactions may remain stable across centuries. To further investigate the dynamics of markets we present the analogy between transfers of money between individuals and the transfer of energy through particle collisions by means of the kinetic theory of gases. We introduce a theoretical framework of how the micro rules of trading lead to the emergence of income and wealth distribution. Particularly, we study the effects of different types of distribution of savings/investments among individuals in a society and different welfare/subsidies redistribution policies. Results show that while considering savings propensities the models approach empirical distributions of wealth quite well the effect of redistribution better captures specific features of the distributions which earlier models failed to do; moreover the models still preserve the exponential decay observed in empirical income distributions reported by tax data and surveys.

  20. Impacts of hypoxia on the structure and processes in pelagic communities (zooplankton, macro-invertebrates and fish

    Directory of Open Access Journals (Sweden)

    W. Ekau

    2010-05-01

    Full Text Available Dissolved oxygen (DO concentration in the water column is an environmental parameter that is crucial for the successful development of many pelagic organisms. Hypoxia tolerance and threshold values are species- and stage-specific and can vary enormously. While some fish species may suffer from oxygen values of less than 3 mL O2 L−1 through impacted growth, development and behaviour, other organisms such as euphausiids may survive DO levels as low as 0.1 mL O2 L−1. A change in the average or the range of DO may have significant impacts on the survival of certain species and hence on the species composition in the ecosystem with consequent changes in trophic pathways and productivity.

    Evidence for the deleterious effects of oxygen depletion on pelagic species is scarce, particularly in terms of the effect of low oxygen on development, recruitment and patterns of migration and distribution. While planktonic organisms have to cope with variable DOs and exploit adaptive mechanisms, nektonic species may avoid areas of unfavourable DO and develop adapted migration strategies. Planktonic organisms may only be able to escape vertically, above or beneath the Oxygen Minimum Zone (OMZ. In shallow areas only the surface layer can serve as a refuge, but in deep waters many organisms have developed vertical migration strategies to use, pass through and cope with the OMZ.

    This paper elucidates the role of DO for different taxa in the pelagic realm and the consequences of low oxygen for foodweb structure and system productivity. We describe processes in two contrasting systems, the semi-enclosed Baltic Sea and the coastal upwelling system of the Benguela Current to demonstrate the consequences of increasing hypoxia on ecosystem functioning and services.
