During the first half of the 1990s, in response to the increasing concern about many of the worlds fisheries and following the United Nations Conference on Environment and Development (UNCED), a number of international fisheries instruments provided an impetus for countries to strengthen their fisheries management. A key step in supporting such efforts is the development of more detailed, systematic and comparable information on fisheries environments and management trends. The State of World Marine Capture Fisheries Management Questionnaire was developed by FAO in 2004 in response to this need. The results have been grouped by region and reported in this publication. Today, we are able to look back to see how countries responded, to examine whether more fisheries are managed, and to determine whether the management tools and strategies employed have improved the overall situation in marine capture fisheries. Trends in legal and administrative frameworks, management regimes and status of marine

The Ostroms framework was used in order to characterize a small-scale fishery SES in Argentina. Several drivers for potential common-management and some detractors from the current common performance were summarized. Despite small-scale fisheries in the region have been considered as a single group of actors given its common history and interactions over the years, we should recognize that artisanal fishery system is at a bifurcation point. The working definition mentioned in Section 3 characterizes a SES as a bio-geo-physical unit… delimited by spatial or functional boundaries. Today, small-scale fisheries in BBE and MH-PC coastal area might be breaking as an entity and facing a reconfiguration of its functional boundaries. The heterogeneous preferences among users (Cinti et al. 2010) and the divergent characteristics of the SES gave rise to different responses to the problem of resource management: the increasing collective-choice and collective-actions towards sustainable management in ...

The Sea Around Us and its worldwide network of collaborators have been involved from the mid-2000s to early 2014 in a massive project of catch reconstruction, devoted to estimating the actual - as opposed to officially reported - catches of the marine fisheries of all countries and territories of the world. These reconstructions, of which well over 200 were completed, used a combination of quantitative and qualitative (scientific and local knowledge) fisheries-related data, to recover components missing from the official statistics, e.g., discards and/or recreational and subsistence fishery catches. The challenges lie in finding and using a combination of qualitative and quantitative information from published scientific and national literature to assemble comprehensive time series of catches for the period 1950-2010 for a defined Exclusive Economic Zone. The opportunities lie in using this knowledge to better understand our impact on marine fisheries resources and to formulate decisions and
Bycatch of protected species in commercial fishing operations is a primary concern to fishery managers because it threatens the conservation, protection, and recovery of fragile species, such as the Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus). One potential solution to reduce the risk associated with commercial fishing operations is to design commercial fishing gear that is more selective in terms of interactions between Atlantic sturgeon and commercial fisheries. Given this conservation and management need, the overarching goal was to reduce Atlantic sturgeon fishery interactions and maintain southern flounder (Paralichthys lethostigma) catch in North Carolina. The specific objectives of this study were to design and evaluate the effectiveness of a modified gillnet. Overall, the results proved that lowering the profile and amount of webbing had a beneficial impact at reducing Atlantic sturgeon incidental encounters and bycatch. The modified gillnet reduced bycatch and Atlantic sturgeon
Managing fisheries is about managing people and businesses, and not about managing fish. Fish populations are managed by regulating the actions of people.[40] If fisheries management is to be successful, then associated human factors, such as the reactions of fishermen, are of key importance, and need to be understood.[41]. Management regulations must also consider the implications for stakeholders. Commercial fishermen rely on catches to provide for their families just as farmers rely on crops. Commercial fishing can be a traditional trade passed down from generation to generation. Most commercial fishing is based in towns built around the fishing industry; regulation changes can impact an entire towns economy. Cuts in harvest quotas can have adverse effects on the ability of fishermen to compete with the tourism industry.[42]. Effective management of fisheries includes involving all stakeholders in the fishery. To do this successfully, stakeholders need to feel empowered enough to make ...
This paper shows that common property problems associated with open access salmon ranching in the absence of a commercial fishery result in inefficiency characterized by overstocking. The presence of an open access fishery presents additional common property problems which will inhibit the development of fish ranching. At prices where salmon ranching does occur, the open access commercial fishery will tend to overexploit the natural fish stock to a greater extent than if there were no salmon ranching. It is shown that there exists a range of prices where both fish stocks can coexist with open access. However, there is a limit price above which the natural stock will be driven to extinction through overfishing stimulated by stock from salmon ranchers. The range of prices under which both species can coexist can be increased through either restrictions of fishery effort or reducing the catchability of aquacultured stock. Cooperative management of both aquaculture and commercial fishing results in profits
This handbook is a unique product. It is the first field guide to community-based fisheries management focused specifically on fisheries, such as those of the Northwest Atlantic, that are already highly regulated by governmental authorities, with licensing and other requirements that limit access and effort. While a variety of resource materials are available on community-based natural resource management, almost all of these are written by practitioners working in the South (developing countries) and rely on case studies and techniques that have been tested in less industrialized tropical fisheries. Therefore, this handbook is one of the few publications about community-based management in Northern fisheries.The need for this handbook was identified by participants working on an initiative on the Atlantic coast of Canada, Turning the Tide: Communities Managing Fisheries Together (www.turningthetide.ca). Turning the Tide works for improved fisheries management through community-based approaches,
Dapeng Bay is a typical offshore fisheries area in the South China Sea (SCS). In order to understand the fishery resources, seasonal variations of species composition, dominant species composition, standardized catch per unit effort (SCPUE) and community diversity of fishery resources in Dapeng Bay, China were analyzed based on trawl survey data in spring (March) and summer (May) of 2013 as well as autumn (August) and winter (December) of 2012. Results demonstrated that there are 113 fishery species, which belong to 78 categories, 50 families, 14 catalogues, 3 classes. There are the most species in summer (61 species) and about 56 species in other seasons. In all four seasons, fish and crustacea are dominant species, and there are the fewest cephalopoda. High values of SCPUE occur in spring and autumn, reaching 5.65 and 5.33, respectively. SCPUE is generally low in summer, ranging between 0.52 - 0.96. Fish biodiversity is the highest in summer and the lowest in winter. Among biodiversity, Shannon-Wiener
For specific management area lines, coordinates, and maps, as well as gear restrictions, see here.. The minimum size limit will remain at 15 inches total length.. The commercial seasons comply with Amendment 2 to the Southern Flounder Fishery Management Plan, adopted by the N.C. Marine Fisheries Commission in August 2019. The plan established the framework for a 62% reduction in southern flounder harvest (compared to 2017) in North Carolina for 2019 and a 72% reduction in harvest beginning in 2020. The reductions are to be achieved through various management measures, including limited recreational and commercial seasons.. Harvest reductions are required because a 2019 South Atlantic Southern Flounder Stock Assessment found that southern flounder is overfished and overfishing is occurring throughout the South Atlantic region. Overfished means the population is too small. Overfishing means the removal rate is too high. North Carolina law mandates that fishery management plans include measures to ...

This document presents the preliminary results of applying the Spatially Explicit Fisheries Risk Assessment framework (SEFRA) developed by New Zealand to assessing the total mortality of great albatross caused by tuna longline operations in the southern hemisphere. The impacts of these mortalities on the sustainability of these albatross species are also considered. Seabird bycatch was modelled as a multiplier of a temporal and spatial overlap between fishing and seabird distributions. Seabird catchability, defined as a combination of seabird-specific vulnerability to fishing gears and gear-specific seabird catchability, was first estimated using the Japanese and New Zealand on-board observer data, and then applied to the total fishing efforts in the southern hemisphere for assessment of total annual bycatch mortality (ABM). High ABMs and high expected risks of longline bycatch to seabird population were identified in particular for wandering albatross, among seven species examined, even though ...

Data and research on agriculture and fisheries including food supply, sustainability, biological resources, and seed, tractor, forest, fruit and vegetable standards., Climate change is becoming more evident and, as it increases, will alter the productivity of fisheries and the distribution of fish stocks. From an economic point of view, the changes will have impacts on fisheries and coastal communities in different ways. These expected changes require adaptable and flexible fisheries and aquaculture management policies and governance frameworks. However, the forms of future climate change and the extent of its impact remain uncertain. Fisheries policy makers therefore need to develop strategies and decision-making models in order to adapt to climate change under such uncertainty while taking into account social and economic consequences. While most work on climate change in the fisheries sector has focused on fisheries science, this book highlights the economic and policy aspects of adapting
Global marine fisheries are currently underperforming, largely due to overfishing. An analysis of global databases finds that resource rent net of subsidies from rebuilt world fisheries could increase from the current negative US$13 billion to positive US$54 billion per year, resulting in a net gain of US$600 to US$1,400 billion in present value over fifty years after rebuilding. To realize this gain, governments need to implement a rebuilding program at a cost of about US$203 (US$130-US$292) billion in present value. We estimate that it would take just 12 years after rebuilding begins for the benefits to surpass the cost. Even without accounting for the potential boost to recreational fisheries, and ignoring ancillary and non-market values that would likely increase, the potential benefits of rebuilding global fisheries far outweigh the costs.
The coastline of the Russian Federation is the fourth longest in the world after the coastlines of Canada, Greenland, and Indonesia. The Russian fishing industry has an exclusive economic zone (EEZ) of 7.6 million km² including access to twelve seas in three oceans, together with the landlocked Caspian Sea and more than two million rivers. According to the FAO, in 2005 the Russian fishing industry harvested 3,190,946 tonnes of fish from wild fisheries and another 114,752 tonnes from aquaculture. This made Russia the ninth leading producer of fish, with 2.3 percent of the world total. Fisheries management is regulated by Russian federal laws. The federal law On Fisheries and Protection of Aquatic Biological Resources of December 2004 (referred to below as the Law on Fisheries) divides fisheries into three main categories industrial, recreational, and subsistence fisheries of indigenous groups. Industrial fisheries includes coastal fisheries. This definition has been challenged and is under ...
The fisheries had achieved their first certification in 2015 after taking up the Western Australian state governments offer to submit themselves to an independent assessment against the MSC requirements. As a condition of the first certification, the two prawn fisheries had been given five years to implement environmental and policy-focused remedial action across 13 areas. These ranged from improving habitat mapping through to getting better information on the bycatch rates from each fishery. For Watson, who supported the efforts of these two world-leading fisheries, recertification gave him a feeling of pride at the hard work the industry and fishery regulator had put in: To come through with no outstanding conditions is such an accolade, he declares. These two fisheries alongside the fisheries regulator have done this through hard work and collaboration. Watson, who is currently based in Fremantle, WA, says the ownership of the issue has been a collective one. The fisheries said: This ...
Income from commercial fishing dramatically declined immediately after the spill, and for a variety of reasons, disruptions to income from commercial fishing continue today, as evidenced by changes in average earnings, ex-vessel prices and limited entry permit values. Natural variability in fish returns and a number of economic changes in the commercial fishing industry since 1989 probably mean that many of these changes in income are not directly attributable to the spill. However, these factors also make discerning spill-related impacts difficult. Economic changes confronting the industry include the increased world supply of salmon (due primarily to farmed salmonids) and corresponding reduced prices, entry restrictions in certain fisheries (such as Individual Fishing Quotas, for halibut and sablefish), allocation changes (e.g., a reduction in the allocation of Cook Inlet sockeye salmon to commercial fishermen), reduction in processing capacity, and spatial limitations of groundfish fisheries ...

Fisheries management is moving in a new direction, and the Fishermens Alliance is excited to be partnering with local fishermen and industry leaders to support the new paradigm. The traditional fisheries management strategy has been to focus on each species in isolation, but the new approach that is being embraced across the country is something called Ecosystem-Based Fisheries Management.. In this new system, the entirety of an ecosystem - food fish, small schooling fish, predators, other marine life and humans - are taken into account, as are changing climate conditions and environmental factors. It provides opportunities to rebuild habitats and fish populations, diversify fishing businesses and better understand the entirety of the marine environment. Check back in the upcoming months to see how you can contribute to this important work. ...

Ecosystem-based fishery management (EBFM) is a new direction for fishery management, essentially reversing the order of management priorities so that management starts with the ecosystem rather than a target species. EBFM aims to sustain healthy marine ecosystems and the fisheries they support. Pikitch et al. describe the potential benefits of implementation of EBFM that, in their view, far outweigh the difficulties of making the transition from a management system based on maximizing individual species. ...
Commonwealth operators catching gummy shark, pink ling and blue eye trevalla in Australias gillnet hook and trap (GHAT) fishery, are now required to start logging their fisheries data electronically from 1 July 2018.. The GHAT sector lands catch worth about $18 million annually and injects funds into regional ports, while supplying the nation with some of Australias most popular table fish.. Australian Fisheries Management Authority (AFMA) CEO, Dr James Findlay, said moving to electronic-logs will streamline the collection of commercial catch data.. Fishers have been looking for cost savings and the move to e-logs will see a significant reduction in the time and cost involved with the old paper-based logbooks, Dr Findlay said.. The e-logs software can be integrated with on-board plotter location systems and fleet management software for vessels that have the systems already installed assist with quicker and better data quality..

1. Introduction. The main fishing resources in Brazil have long been overexploited, so that regulatory measures have been taken to prevent the collapse of fisheries (Peres et al., 2001). Some management measures are developed from common knowledge and long-term observation in traditional management systems, such as limited access, seasonal limits, protection of reproductive stocks or juveniles, among others (Berkes et al., 2006). Those measures do not often reach the goal to which they are created, that is, to preserve stocks.. Small-scale fisheries are of great social and economic importance in the fisheries sector, being responsible for a large number of jobs in coastal communities. According to IBAMA (2008), fishing contributes approximately 65.2% of national production of fish in coastal waters. From about 25 thousand vessels of the national fleet, around 23 thousand correspond to the small scale fleet (Dias-Neto and Marrul-Filho, 2003).. The Cananéia, Iguape and Ilha Comprida Estuarine ...
Fishing is a social and economic activity, and consequently socio-economic considerations are important for resource management. While this is acknowledged in the theory of Ecosystem-Based Management (EBM) and its sector-specific development Ecosystem-Based Fisheries Management (EBFM), currently applied fishery management objectives often ignore economic considerations.Year-to-year management, however, implicitly responds to short-term economic interests, and consequently, regularly resorts to tactical short-term rather than strategic long-term decisions.The aim of this article is to introduce a new way of estimating management advice referred to as an ecologically-constrained Maximum Economic Yield (eMEY) strategy, which takes into account ecological criteria as well as short- to medium-term economic costs. We further illustrate what net cost reductions per year are possible applying the eMEY strategy compared with the existing way of setting total allowable catches (TACs). The eMEY approach aims at

OBJECTIVES: To evaluate the effectiveness of the United States Commercial Fishing Industry Vessel Safety Act of 1988 in reducing the high occupational death rate (200/100,000/year in 1991-2) among Alaskas commercial fishermen. METHODS: Comprehensive surveillance of deaths in commercial fishing was established by our office during 1991 and 1992 for Alaska. Demographic data and data on risk factors and incidents were compiled and analysed for trend. RESULTS: During 1991-8, there was a significant (p , 0.001) decrease in deaths in Alaska related to commercial fishing. Although drownings from fishermen falling overboard and events related to crab fishing vessels (often conducted far offshore and in winter) have continued to occur, marked progress (significant downward trend, p , 0.001) has been made in saving the lives of people involved in vessels capsizing and sinking. CONCLUSIONS: Specific measures tailored to prevent drowning associated with vessels capsizing and sinking in Alaskas commercial ...
The Norwegian fishery of spurdog (Squalus acanthias L.), which started in 1930, has played a dominant part in the fishery for this species in Europe. During 1963-1968 a change occured in the behaviour of the spurdog stock. The spurdogs left the traditional fishing grounds, and this lead to a depression in the Norwegian fishery. New concentrations were discovered in the southern North Sea during the autumn 1968. Several tagging experiments, 1975-1979, indicate that the spurdogs in this area migrate to the area north of Scotland during the spring. Recaptures from taggings 1959-1966 together with information on Scottish spurdog catches during 1947- 1957, indicate that the spurdogs in the southern North Sea belong to the Scottish-Norwegian spurdog stock. During the last two years the Norwegian longline fishery for spurdogs has been greatly reduced. Length distributions indicate that maturing and mature females which constitute the main part of the Norwegian catch, were heavily reduced in numbers ...
There is unanimous agreement that the functional role of parrotfish as lower trophic level herbivores is a key component in the structural integrity and resiliency of shallow water coral reef ecosystems. The premise for carrying out a comprehensive fishery, biological and ecological investigation of parrotfishes here was based on the recognition that more concerted research is needed in order to help address management and conservation challenges related to parrotfish fisheries. More importantly, it was decided from the outset that urbanized fisheries posed the greatest threat to coral reef fish assemblages, which prompted me to place the investigation of parrotfish ecology within the context of a typical artisanal fishery case study in the South Pacific (i.e. Solomon Islands).. I feel some vindication for the research theme adopted for this PhD given the recognition of both parrotfish assemblage decline and open-access urban fisheries by the 11th International Coral Reef Symposium, held in the ...
The Status of South Australian Fisheries Report covers marine, estuarine and freshwater fish, crustaceans and shellfish.The fish were selected due to their importance to the states commercial and recreational sectors.. Fisheries Minister Leon Bignell said the fishing industry supported more than 3000 jobs - mainly in the states regions.. The states commercial fisheries process more than 44,000 tonnes of seafood for domestic and international markets each year, contributing more than $379 million to our economy, Mr Bignell said.. Recreational fishing is also a strong economic driver, with more than one in six South Australians and interstate and international visitors enjoying recreational fishing on our seas, rivers and estuaries each year.. Our fish stocks are a precious resource but they are constantly changing because of environmental conditions, natural population fluctuations and fishing pressure.. The State Government will continue to monitor stocks and work with all fishing ...
Compared to the general population in Uganda, fishing communities suffer greater burden of HIV/AIDS. We determined the level of comprehensive knowledge on HIV prevention and its associated factors among fishing communities of Lake Kyoga. We conducted secondary analysis of data from the Lake Kyoga Behavioral Survey, a population-based sample survey on behavioral risk factors for HIV, syphilis, and schistosomiasis among adults in fishing communities of Lake Kyoga in 2013. We defined comprehensive knowledge as having correct knowledge on HIV prevention (consistent condom use, faithfulness, a healthy-looking person can have HIV, and HIV cannot be transmitted through food-sharing, witchcraft or handshake). We used logistic regression to determined potential factors associated with comprehensive knowledge on HIV prevention and control for confounding. Of 1780 persons in the sample, 51% (911/1780) were females. The mean age was 32 (range: 15-97) years. Overall, 51% (899/1780) of persons had comprehensive

So, heres what I did to try to answer some of my research questions and contribute to what we know about tiger sharks in the northwest Atlantic and Gulf of Mexico. The number one question I get about my research is whether or not I found any license plates in any of the stomachs (I did not and youve been watching too much Jaws. But to be fair, license plates have been found in the stomachs of tiger sharks before), or any human remains (I didnt find those either). The second most popular question I get is where do you get shark stomachs from? Sharks were collected from commercial fishermen in the shark bottom longline fishery. This is totally legal, and the stomachs themselves are collected by NOAA observers. Observers collect data at sea while on commercial fishing vessels. The shark is measured, sex is recorded, and the stomachs are removed. Most of the rest of the shark would go to the fishermen. Another portion of my stomachs came from a survey run by the National Marine Fisheries ...
Individual sandbar sharks would generally not approach the metal ingots closer than about 24 inches, nor attack pieces of cut bait suspended within approximately 12 inches, said Richard Brill, a research scientist at NOAAs Northeast Fisheries Science Center and head of the Cooperative Marine Education and Research (CMER) Program at the Virginia Institute of Marine Science. This study clearly shows the alloy has the potential to repel sharks from pelagic longline fishing gear so they are not caught as bycatch, but the optimal size and shape of the alloy and other factors needs to be determined. This is a promising step ...
The red mangrove crab, Goniopsis cruentata, influences the recruitment and composition of plant species in the mangrove ecosystem and it is an important fishery resource. Nevertheless, no current management and conservation plans are available for this species for the Brazilian coast. This investigation evaluated the population structure and reproductive biology in populations of G. cruentata under contrasting fishery pressures. The sampling program was carried out in two mangroves, Vaza-Barris and Sergipe River, from January through December 2011. Crabs from both mangroves were randomly collected by a professional fisherman during daytime low tide periods, using a fishing rod baited with pieces of a locally abundant gastropod, Pugilina morio, during 20min/area (catch per unit effort). Monthly measurements of air, sediment surface layer and water temperatures were obtained with a digital thermometer and salinity with an optical refractometer. Both crab populations were compared concerning their ...

Atlantic Highly Migratory Species; Public Conference Call Regarding Recreational Yellowfin Tuna Fishery Data Collection, 24669-24670 [2012-9971]
Concern for the status of Carcharhinus signatus off South America arises from uncontrolled fishing effort on the species and from its comparatively low biological productivity. Under intense fishing pressure off parts of Brazil, C. signatus is a target species (for fins and meat) regularly caught in commercial fisheries on seamounts off northeastern Brazil where the species aggregates. The Night Shark is the most important elasmobranch species in the seamount area where it makes up 90% of catches from over shallow banks. Estimates of age composition indicated that 89.2% of individuals were below the age at 50% maturity. Demographic analysis indicates declines due to fishing mortality rate and early recruitment to the fishery. It is likely that there are no significant natural refuges for the species and that there is little or no exchange with other populations of C. signatus. Formerly common in Caribbean fisheries, this species is now apparently rare. Historically, night sharks comprised a ...
Blue fin tuna ranching is also being done in Mexico, targeting populations of the smaller-sized Pacific blue fin that are thought to be in better shape that their Atlantic cousins. But given that the overall hunt for tuna throughout the Pacific is steadily growing, many marine biologists believe that its only a matter of time before Pacific populations are over-exploited. Another issue again centers around the fact that these top predators are fed enormous volumes of forage fish, which critics say can have negative impacts on marine ecosystems and may involve health risks to humans due to the accumulation of toxics like dioxins and PCBs. In a world where fish populations have been steadily declining, they say this form of aquaculture consumes far more fish protein than it creates. ...
The eastern Baltic (EB) cod (Gadus morhua) stock was depleted and overexploited for decades until the mid-2000s, when fishing mortality rapidly declined and biomass started to increase, as shown by stock assessments. These positive developments were partly assigned to effective management measures, and the EB cod was considered one of the most successful stock recoveries in recent times. In contrast to this optimistic view, the analytical stock assessment failed in 2014, leaving the present stock status unclear. Deteriorated quality of some basic input data for stock assessment in combination with changes in environmental and ecological conditions has led to an unusual situation for cod in the Baltic Sea, which poses new challenges for stock assessment and management advice. A number of adverse developments such as low nutritional condition and disappearance of larger individuals indicate that the stock is in distress. In this study, we (i) summarize the knowledge of recent changes in cod ...

At the heart of the initiative is the FiTI Standard, an internationally recognised guideline on what information on fisheries should be published online by public authorities. It is made up of 12 transparency requirements which are applicable for all countries covering public registry of national fisheries laws, regulations and official policy documents, the publication of all foreign fishing access agreements, information on the large and small-scale sector, information on the post-harvest sector and fish trade, and subsidies, among others.. In Seychelles, the implementation of FiTI is led by a National Multi-Stakeholder group. The group consists of 12 voting members - four representatives each from government, business and civil society. The group is chaired by the Seychelles FiTI National Lead, Philippe Michaud, who is also Seychelles senior advisor to the Blue Economy.. Such a report will show that we can have a discussion around the fisheries sector, involving everyone. It will also give ...
This shark is caught regularly in gillnet and longline fisheries throughout its range. In northern Australia, Lyle and Timms (1984) reported that in gillnets C. amblyrhynchoides made up 1.5% of the shark catch by numbers and 2.7% by weight. Lyle and Griffin (1987) reported that in longline catches in northern Australia it comprised 0.2% of the shark catch by number and 0.6% by weight. Current levels of the catch of sharks in northern Australia are low. However, catch levels during the 1970s and 1980s were considerably higher when foreign gillnet vessels operated in the fishery. Foreign vessels caught up to 17,000 t of sharks annually during this period (Bentley 1996), but ceased fishing in Australian waters in 1986 when the length of gillnets was restricted ...

Atlantic menhaden (Brevoortia tyrannus) plays an important role in linking production from lower trophic levels to diverse marine predators and supporting the largest commercial fishery on the U.S. east coast. A significant management controversy has arisen because of uncertainties over their movement into and out of the Chesapeake Bay and the size or age-dependent vulnerability of fish to the commercial fishery. A landmark mark-recapture study of Atlantic menhaden was conducted during the 1960s-70s, which allows estimation of movement rates. Over one million menhaden were tagged, and over 200,000 tags were recovered, but the data were never fully analyzed. Using these data, this study will obtain estimates of migration rates and selectivity patterns, develop maps of the menhadens range, and obtain estimates of the impact of the spatial distribution of the fishery on menhaden. These results will substantially improve our knowledge of menhaden population dynamics (migration and mortality rates), ...
Wild fisheries for Arctic char exist near Cambridge Bay and Cumberland Sound in Nunavut, Canada. Arctic char fisheries in the Nunavut Settlement Area are co-managed by the Department of Fisheries and Oceans Canada (DFO), the Nunavut Wildlife Management Board, regional wildlife organizations, and hunter and trapper organizations in accordance with the Nunavut Land Claims Agreement, the Fisheries Act, and in some communities, by the bylaws of local hunter and trapper organizations. Among management measures for Arctic char in Nunavut are: minimum gillnet mesh sizes, license controls, river-specific quotas and total harvest limits, and community-based monitoring. The fishery is well managed, but management is considered to be complex due to the widespread distribution and biological nature of Arctic char as well as a lack of recorded harvesting data. Currently, only local Inuit community members are allowed to participate in the fishery.. The Department of Fisheries and Ocean (DFO) and various ...

The Northwest Fisheries Science Center has been collecting cost earnings data since 2003. The Center economists survey all commercial fishing vessels on the West Coast of the United States from San Diego, CA to Blaine, WA. These vessels range in size from less than 40 feet to more than 300 feet and the types of companies range from family-run operations to large multinational companies. The data collection program includes both voluntary surveys as well as mandatory surveys. Collecting data in different formats from a wide range of participants provides a unique perspective on best practices of data collection programs. We will emphasize lessons learned from conducting more than 10 years of data collections and compare and contrast the advantages and disadvantages to voluntary and mandatory economic data collection programs ...
Rebuilding the fisheries and agricultural sectors on Abaco and Grand Bahama post-Hurricane Dorian will require the creation of a complete and extensive registry of participants in the field, as well as ensuring facilities and machinery are properly reconstructed to code, the Inter-American Development Bank (IDB) has cautioned.. The fisheries and agricultural industries, two very important components of those islands economies, sustained a combined $14 million in damage and $11 million in losses according to the recently released Assessment of the Effects and Impacts of Hurricane Dorian in The Bahamas report.. The report outlines recommendations for the fisheries sector, including that it is necessary to establish a complete registry of all vessels and fishermen devoted to the sector to mitigate against future losses in the event of another catastrophic event.. This will help in the design of a plan for the recovery of the sector and to better target the allocation of reconstruction ...

Traditional aquaculture has to a large extent used herbivore species with limited requirements for additional feeding. However, in intensive aquaculture production one farm carnivore species like salmon and also feeds herbivore species with fishmeal as this increase growth. This has lead to a growing concern that increased aquaculture production poses an environmental threat to the species targeted in reduction fisheries as increased demand increase fishing pressure. In this paper we address this question along two lines. First, under which management regimes may increased demand pose a threat to the species in question. Second, we investigate what is the market for fishmeal. Is fishmeal a unique product or is it a part of the larger market for oilmeals which includes soyameal? This is an important issue since the market structure for fishmeal is instrumental for whether increased aquaculture production may affect fishmeal prices, and thereby increase fishing pressure in industrial fisheries ...
Aquaculture, the worlds fastest-growing food production sector, is set to overtake capture fisheries as the major source of seafood and projected to provide 62 per cent of global seafood by 2030. Global demand for seafood is increasing and capture fisheries are at, or in some locations may have exceeded, their maximum sustainable yield; therefore, to meet future demand, the growth of aquaculture production will need to increase.. In 2014/15, the value of Australian aquaculture production was approximately $1.2 billion and accounted for 43 per cent of the value of Australian fisheries production. The largest Australian aquaculture industry sector is Tasmanian salmon, which continues to grow substantially and in 2014/15 was worth nearly $650 million. In Australia, for the decade 2004/05 to 2014/15, the pattern of production has changed significantly, with a shift from the production of wild-caught stocks (down 84,711 tonnes) towards production of aquaculture products (up 41,053 ...

Snook Centropomus spp. were an important commercial fishery is South Texas until the population crashed in the late 1930s. As snook numbers increase again in South Texas, biologically pertinent information is needed for the proper management of this growing fishery. Two important questions are: 1) what is the genetic structure of snook, and 2) are snook breeding in Texas waters? Currently, such information does not exist. As part of a larger study, the goal of this project is to provide important baseline genetic data for snook in South Texas. Samples from adult snook and young-of-the-year (YOY) were collected and analyzed for 10 species specific microsatellite markers using standard population genetic techniques and statistics. A sibship analysis will be performed on YOY to determine if they could have been produced by local adults, indicating a local breeding population. This project will also utilize geographic information system (GIS) methods to determine areas of high genetic diversity ...
This collaborative study between the National Oceanic and Atmospheric Administration National Marine Fisheries Service, Sea Mammal Research Unit, and Fisheries and Oceans Canada investigated the relationship between diet and population trends of Steller sea lions in the Aleutian Islands. During this study, data from a total of 3,118 samples collected throughout the year in the Aleutian Islands from 1990-2012 (including 399 samples collected during this study at 14 sites (NPRB #1114: 345 in March 2012 and 54 in summer 2012) and 305 samples collected during NPRB #720) were analyzed to characterize the spatial, temporal and seasonal variation in sea lion diet and examined the relationship between population trend and diet diversity in both seasons and throughout the year. Additionally, a combination of dietary information methods, including traditional hard part identification and a molecular methodology developed by Tollit et al. (2009) that found DNA extracted from the soft scat of wild Steller ...

Mark Powell, vice president of fish conservation for the nonprofit Ocean Conservancy advocacy group, has made sweeping changes to help restore the Gulf of Mexico red snapper population by lobbying government groups and partnering with some of Americas most powerful fish buyers. Because of generations of overfishing, the snapper population has dwindled to three percent of what it was 125 years ago. Last year, Ocean Conservancy successfully pushed the Gulf of Mexico Fishery Management Council to limit by about half the number of red snapper that commercial fishermen can catch, and advised shrimpers to reduce accidental bycatch of snapper by about three-quarters. To aid the cause, Ocean Conservancy met with mammoth retailer Wal-Mart and its shrimp suppliers and urged for the reduction of snapper bycatch (Wal-Mart has pledged to sell only Marine Stewardship Council-certified fish by 2011). Powell is also working with Bob Sullivan, the corporate CEO of the Chicago-based Plitt Company, which supplies ...
Sturgeon first appear in the fossil record in the Triassic Period just over 200 million years ago and are among the most primitive of the bony fishes. Despite their large size and historic presence along the East Coast, Atlantic sturgeon were not targeted for their meat and caviar as a commercial fishery until 1880. By 1905 they had declined to less than one percent of their pre-fishing abundance but the fishery continued. Prior to 1980, there had been very little research on Atlantic sturgeon, primarily limited to documenting landing location and poundage, maximum longevity, or weight of eggs per fish. By 1990 most research into Atlantic sturgeon population dynamics had been focused on fisheries, and specifically, on when, where, and in what condition they were available for capture. The first true efforts at understanding population dynamics of Atlantic sturgeon led to the closure of all U.S. state and federal fisheries in 1998 and 1999, respectively. Much of the initial research on Atlantic sturgeon
Saturday 9 September 2017, scientists from DTU Aqua (Denmark), SLU (Sweden) and WWF in cooperation with dozens of volunteer recreational fishermen successfully tagged and released 5 bluefin tuna in the Skagerrak. The sizes of the tagged tunas are estimated to be approximately 130-285 kg, making these tunas some of the largest predatory fish in waters in Denmark and Sweden. This is the first time that bluefin tuna have been tagged in Danish and Swedish waters.. The advanced data storage tags will let scientists describe the migration and distribution of bluefin tuna and their geographic origin (e. g., Mediterranean Sea or Gulf of Mexico). The information will help scientists understand why bluefin tuna have re-appeared in Scandinavian waters and can be used to develop and support sustainable fisheries for bluefin tuna in the Atlantic Ocean and Mediteanean Sea.. The day is also historic because it marks the first time since the 1960s that it is allowed to have a fishery for bluefin tuna in these ...

The earliest steam-powered fishing boats first appeared in the 1870s and used the trawl system of fishing as well as lines and drift nets. These were large boats, usually 80-90 feet (24-27 m) in length with a beam of around 20 feet (6.1 m). They weighed 40-50 tons and travelled at 9-11 knots (17-20 km/h; 10-13 mph). The earliest purpose-built fishing vessels were designed and made by David Allan in Leith in March 1875, when he converted a drifter to steam power. In 1877, he built the first screw-propelled steam trawler in the world. This vessel was Pioneer LH854. She was of wooden construction with two masts and carried a gaff-rigged main and mizen using booms, and a single foresail. Allan argued that his motivation for steam power was to increase the safety of fishermen. However local fishermen saw power trawling as a threat. Allan built a total of ten boats at Leith between 1877 and 1881. Twenty-one boats were completed at Granton, his last vessel being Degrave in 1886. Most of these were sold ...
Just about every fisherman is aware of how many great fishing locations there are in America. Each and every state has its very own perfect fishing spots that are perfect for fishing a number of different species. However, if you are partial to crappie fishing, you may want to consider packing up your fishing gear and heading to the state of Oklahoma.

Being able to learn particular methods and techniques may help you to get an edge on your Oklahoma fishing experience, but being that crappie are so full of surprises, you will most likely need to be prepared for anything. ...
The fishery is also important to the national economy and contributes to improving the trade balance. In 2012, this sector contributed 7.5% towards the GDP of the primary sector and 2.2% towards the total GDP. It also generates direct and indirect jobs for 17% of the working population. Of note is the fact that the impacts of climate change have caused many farmers to turn to the fishery for their livelihoods. This has led to an increase in the numbers of artisanal fishermen while also threatening fishery resources. In some aquatic environments, in addition to resources being overexploited, new environmental conditions have been created by certain activities (for example, the establishment of dams in the Senegal River delta zone has favored the proliferation of certain species, such as Typha domingensis). In marine and coastal ecosystems, the high value placed on certain species, overfishing and an increase in population along the coast are negatively impacting resources (such factors have led ...
Sea bass is and always has been a very important fish for recreational sea anglers. However, since commercial fishing for bass took off in the 1970s the stock has become overexploited, with fever and smaller bass left in our waters as the result. The European Anglers Alliance (EAA) and the European Fishing Tackle Trade Association (EFTTA) pushed for more than a decade that the EU should curb overfishing of sea bass, and increase the minimum landing size. The Member States were well aware that the bass was in trouble but delayed the adoption of any management measures for years. Finally, the EU Commission by itself put in place emergency measures in 2015 and increased the minimum landing size from 36 cm to 42 cm for bass fisheries in North Atlantic waters. Today, additional management measures have been adopted by the Member States and put in place. Unfortunately, these measures hit hard recreational sea anglers, who have been restricted to release all bass they catch the first half of the year ...
Comparative cardiovascular effects of four fishery anesthetics in spinally transected rainbow trout, Oncorhynchus mykiss. Fredricks, K. T., Gingerich, W. H., and Fater, D. C., 1993, Comparative cardiovascular effects of four fishery anesthetics in spinally transected rainbow trout, Oncorhynchus mykiss: Comparative Biochemistry and Physiology C, v. 104C, no. 3, p. 477-483.. Abstract. We compared the effects of four anesthetics on heart rate, dorsal and ventral aortic blood pressure, and electrocardiograms of rainbow trout (Oncorhynchus mykiss ). Exposure to the local anesthetics tricaine methanesulfonate (MS-222) and benzocaine hydrochloride (BZH) produced minimal cardiovascular alterations. Mean dorsal aortic pressure (DAP) decreased during exposure to MS-222, and mean DAP and mean ventral aortic pressure (VAP) increased 15% during recovery from BZH. Exposure to the general anesthetic 2-phenoxyethanol (2-PE) or the hypnotic agent etomidate (ET) dramatically decreased heart rate and blood ...
Not much change for spring chinook fishing along the Lower Columbia River, and I had a chance to get a first-hand look at the mighty river while crossing the I-5...
