The sequence of transfers of matter and energy from organism to organism in the form of FOOD. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. PLANTS, which convert SOLAR ENERGY to food by PHOTOSYNTHESIS, are the primary food source. In a predator chain, a plant-eating animal is eaten by a larger animal. In a parasite chain, a smaller organism consumes part of a larger host and may itself be parasitized by smaller organisms. In a saprophytic chain, microorganisms live on dead organic matter.
Total mass of all the organisms of a given type and/or in a given area. (From Concise Dictionary of Biology, 1990) It includes the yield of vegetative mass produced from any given crop.

Different prevalences of Renibacterium salmoninarum detected by ELISA in Alaskan chinook salmon Oncorhynchus tshawytscha spawned from freshwater and seawater. (1/711)

Soluble antigen of Renibacterium salmoninarum (Rs) was detected by a polyclonal enzyme-linked immunosorbent assay (ELISA) at significantly higher prevalences in adult chinook salmon Oncorhynchus tshawytscha that matured in freshwater than in the same cohort of fish spawned after maturation in seawater. The cumulative results were consistent during 4 yr of comparison at the Little Port Walter Hatchery on Baranof Island, Alaska, USA. Possible causes for this difference are discussed. Maturation of chinook salmon broodstock in seawater has become a practical strategy at this hatchery to reduce the prevalence of Rs-positive parent fish and the numbers of culled eggs.  (+info)

Relative virulence of three isolates of Piscirickettsia salmonis for coho salmon Oncorhynchus kisutch. (2/711)

Piscirickettsia salmonis was first recognized as the cause of mortality among pen-reared coho salmon Oncorhynchus kisutch in Chile. Since the initial isolation of this intracellular Gram-negative bacterium in 1989, similar organisms have been described from several areas of the world, but the associated outbreaks were not reported to be as serious as those that occurred in Chile. To determine if this was due to differences in virulence among isolates of P. salmonis, we conducted an experiment comparing isolates from Chile, British Columbia, Canada, and Norway (LF-89, ATL-4-91 and NOR-92, respectively). For each of the isolates, 3 replicates of 30 coho salmon were injected intraperitoneally with each of 3 concentrations of the bacterium. Negative control fish were injected with MEM-10. Mortalities were collected daily for 41 d post-injection. Piscirickettsiosis was observed in fish injected with each of the 3 isolates, and for each isolate, cumulative mortality was directly related to the concentration of bacterial cells administered. The LF-89 isolate was the most virulent, with losses reaching 97% in the 3 replicates injected with 10(5.0) TCID50, 91% in the replicates injected with 10(4.0) TCID50, and 57% in the fish injected with 10(3.0) TCID50. The ATL-4-91 isolate caused losses of 92% in the 3 replicates injected with 10(5.0) TCID50, 76% in the fish injected with 10(4.0) TCID50, and 32% in those injected with 10(3.0) TCID50. The NOR-92 isolate was the least virulent, causing 41% mortality in the replicates injected with 10(4.6) TCID50. At 41 d post-injection, 6% of the fish injected with 10(3.6) TCID50 NOR-92 had died. Mortality was only 2% in the fish injected with 10(2.6) TCID50 NOR-92, which was the same as the negative control group. Because the group injected with the highest concentration (10(4.6) TCID50) of NOR-92 was still experiencing mortality at 41 d, it was held for an additional 46 d. At 87 d post-injection, the cumulative mortality in this group had reached 70%. These differences in virulence among the isolates were statistically significant (p < 0.0001), and are important for the management of affected stocks of fish.  (+info)

Further observations on the epidemiology and spread of epizootic haematopoietic necrosis virus (EHNV) in farmed rainbow trout Oncorhynchus mykiss in southeastern Australia and a recommended sampling strategy for surveillance. (3/711)

Epizootic haematopoietic necrosis virus (EHNV) is an iridovirus confined to Australia and is known only from rainbow trout Oncorhynchus mykiss and redfin perch Perca fluviatilis. Outbreaks of disease caused by EHNV in trout populations have invariably been of low severity, affecting only 0+ post-hatchery phase fingerlings < 125 mm in length. To date the virus has been demonstrated in very few live in-contact fish, and anti-EHNV antibodies have not been found in survivors of outbreaks, suggesting low infectivity but high case fatality rates in trout. During an on-going study on an endemically infected farm (Farm A) in the Murrumbidgee River catchment of southeastern New South Wales, EHNV infection was demonstrated in 4 to 6 wk old trout fingerlings in the hatchery as well as in 1+ to 2+ grower fish. During a separate investigation of mortalities in 1+ to 2+ trout on Farm B in the Shoalhaven River catchment in southeastern New South Wales, EHNV infection was demonstrated in both fingerlings and adult fish in association with nocardiosis. A 0.7% prevalence of antibodies against EHNV was detected by ELISA in the serum of grower fish at this time, providing the first evidence that EHNV might not kill all infected trout. EHNV infection on Farm B occurred after transfer of fingerlings from Farm C in the Murrumbidgee river catchment. When investigated, there were no obvious signs of diseases on Farm C. 'Routine' mortalities were collected over 10 d on Farm C and EHNV was detected in 2.1% of 190 fish. Tracing investigations of sources of supply of fingerlings to Farm B also led to investigation of Farm D in Victoria, where the prevalence of anti-EHNV antibodies in 3+ to 4+ fish was 1.3%. The results of this study indicate that EHNV may be found in trout in all age classes, need not be associated with clinically detectable disease in the population, can be transferred with shipments of live fish, can be detected in a small proportion of 'routine' mortalities and may be associated with specific antibodies in a small proportion of older fish. Sampling to detect EHNV for certification purposes should be based on examination of 'routine' mortalities rather than random samples of live fish. Antigen-capture ELISA can be used as a cost effective screening test to detect EHNV on a farm provided that sampling rates conform with statistical principles.  (+info)

Molecular characterization of the myxosporean associated with parasitic encephalitis of farmed Atlantic salmon Salmo salar in Ireland. (4/711)

During seasonal epizootics of neurologic disease and mass mortality in the summers of 1992, 1993 and 1994 on a sea-farm in Ireland, Atlantic salmon Salmo salar smolts suffered from encephalitis associated with infection by a neurotropic parasite. Based on ultrastructural studies, this neurotropic parasite was identified as an intercellular presporogonic multicellular developmental stage of a histozoic myxosporean, possibly a Myxobolus species. In order to generate sequence data for phylogenetic comparisons to substantiate the present morphological identification of this myxosporean in the absence of detectable sporogony, polymerase chain reaction (PCR), Southern blot hybridization, dideoxynucleotide chain-termination DNA sequencing, and in situ hybridization (ISH) were used in concert to characterize segments of the small subunit ribosomal RNA (SSU rRNA) gene. Oligonucleotide primers were created from sequences of the SSU rRNA gene of M. cerebralis and were employed in PCR experiments using DNA extracted from formalin-fixed paraffin-embedded tissue sections of brains from Atlantic salmon smolts in which the myxosporean had been detected by light microscopy. Five segments of the SSU rRNA gene of the myxosporean, ranging in length from 187 to 287 base pairs, were amplified, detected by hybridization with sequence-specific probes, and sequenced. Consensus sequences from these segments were aligned to create a partial sequence of the SSU rRNA gene of the myxosporean. Assessments of sequence identity were made between this partial sequence and sequences of SSU rRNA genes from 7 myxosporeans, including Ceratomyxa shasta, Henneguya doori, M. arcticus, M. cerebralis, M. insidiosus, M. neurobius, and M. squamalis. The partial SSU rRNA gene sequence from the myxosporean had more sequence identity with SSU rRNA gene sequences from neurotropic and myotropic species of Myxobolus than to those from epitheliotropic species of Myxobolus or Henneguya, or the enterotropic species of Ceratomyxa, and was identical to regions of the SSU rRNA gene of M. cerebralis. Digoxigenin-labeled oligonucleotide DNA probes complementary to multiple segments of the SSU rRNA gene of M. cerebralis hybridized with DNA of the parasite in histologic sections of brain in ISH experiments, demonstrating definitively that the segments of genome amplified were from the organisms identified by histology and ultrastructural analysis. Based on sequence data derived entirely from genetic material of extrasporogonic stages, the SSU rDNA sequence identity discovered in this study supports the hypothesis that the myxosporean associated with encephalitis of farmed Atlantic salmon smolts is a neurotropic species of the genus Myxobolus, with sequences identical to those of M. cerebralis.  (+info)

Aspects of the epizootiology of pancreas disease in farmed Atlantic salmon Salmo salar in Ireland. (5/711)

A computerised database containing information on over 17.8 million salmon contained within 49 separate marine populations was used to study the epidemiology of pancreas disease (PD) in Ireland. Of the 43 recorded PD outbreaks, 57% occurred in the 3 mo period August to October inclusive (17 to 32 wk post-transfer). Analysis of variance of mortality rates during PD outbreaks occurring on 6 marine sites over a 5 yr period showed that mortality rates vary significantly between sites (p < 0.001) but not between years over this time period. The mortality rate during PD outbreaks ranged from 0.1 to 63%. Mortality rates were significantly higher when PD outbreaks occurred earlier in the year (y = -1.28x + 59, SE of b 0.33). The mean length of a PD outbreak was 112 d (SE = 7.7, n = 37). There was no correlation between PD mortality rate and smolt input weight, initial stocking density and transfer mortality.  (+info)

Streptococcus iniae, a bacterial infection in barramundi Lates calcarifer. (6/711)

The cause of ongoing mortality in barramundi Lates calcarifer (Bloch) in seawater culture was identified as Streptococcus iniae by biochemical and physiological tests. This is the first published record of this bacterial species in Australia and the first confirmed report of S. iniae causing mortality in barramundi. The bacterium was highly pathogenic for barramundi when challenged by bath exposure. The pathogen was found to have a LD50 of 2.5 x 10(5) and 3.2 x 10(4) colony-forming units at 48 h and 10 d respectively. Experimental challenge of barramundi resulted in high levels of mortality (> 40%) within a 48 h period. Ten days after the challenge, S. iniae could not be isolated from kidney, spleen, liver or eye of surviving fish. However, the organism was easily isolated from the brain of both moribund and healthy fish, indicating that barramundi can carry the bacterium asymptomatically.  (+info)

Ichthyophthiriasis in carp Cyprinus carpio: infectivity of trophonts prematurely exiting both the immune and non-immune host. (7/711)

Ichthyophthirius multifiliis exposed to naturally immunised carp established short-term infections, the majority of parasites actively emerging within 2 h of entering the epidermis. A small, but significant, number of these expelled parasites were shown to retain theront-like properties with the capacity to directly re-invade a further fish host. Infectivity fell rapidly with time in the host and was comparable to that of trophonts of a similar age artificially induced to emerge from non-immune hosts with the aid of MEM (minimal essential medium). Trophonts recovered with MEM from immune carp 2 to 8 h post infection rarely established infections upon exposure to susceptible new hosts and no infections resulted from older trophonts recovered after 8 to 24 h exposure; older trophonts, however, represented only a small percentage of the original parasite population. A low level of infectivity was recorded in trophonts collected with the aid of MEM from non-immune carp after up to 24 h of infection. The results are discussed in relation to theront transformation and evasion of the host immune response.  (+info)

Molecular evidence that the proliferative kidney disease organism unknown (PKX) is a myxosporean. (8/711)

The proliferative kidney organism unknown (PKX), a serious salmonid fish pathogen, is considered to be a myxosporean on the basis of ultrastructural studies, but its real taxonomic position has never been confirmed. In order to ascertain its position, genomic DNA was extracted from PKX and small subunit (SSU) ribosomal DNA was amplified by PCR, cloned and sequenced. A phylogenetical analysis on SSU rDNA from 76 or 128 eucaryotic species was carried out. Whatever the tree reconstruction methods used, PKX was found to be a sister group of the Myxozoa phylum, providing the first molecular evidence for its membership in this phylum.  (+info)

For the seminar Unpacking the 90% - a comprehensive look at small-scale fisheries, Ratana shared TBTIs vision and work with about 30 attendants, being very well received by the centre and university audience. Her presentation highlighted key challenges associated with small-scale fisheries research and governance and offered suggestions about ways forward.. According to her, small-scale fisheries are the dominating sector in terms of number of people involved and contribution to local food security and sustainable livelihoods around the world. Yet, information and knowledge about small-scale fisheries is still incomplete, making it difficult for the sector to realize its potentials.. She further explained that with the current concern about overexploitation and unsustainable development of fisheries and marine resources, and about the overall health of the aquatic ecosystems, greater attention is required to enhance our understanding about small-scale fisheries, where solutions to some of the ...
Concern over illegal, unreported and unregulated (IUU) fishing has led to a number of policy, trade and surveillance measures. While much attention has been given to the impact of IUU regulation on industrial fleets, recognition of the distinct impacts on small-scale fisheries is conspicuously lacking from the policy and research debate. In this paper, we outline three ways in which the application of IUU discourse and regulation undermines small-scale fisheries. First, the mainstream construction of illegal, unreported and unregulated fishing, and also the categorical use of IUU in an all-inclusive sense, disregards the diversity, legitimacy and sustainability of small-scale fisheries practices and their governing systems. Second, we explore how the recent trade-related measures to counter IUU fishing mask and reinforce existing inequalities between different sectors and countries, creating an unfair burden on small-scale fisheries and countries who depend on them. Third, as IUU fishing ...
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

Existing scholarly works have paid little or no attention to the problems small-scale fisheries encounter within the context of food and nutritional security. Therefore, this work has examined the problem. Small-scale fisheries (SSF) are the dominant source of local fish production in Nigeria and, like many fisheries worldwide, receive inadequate attention for their significance within the context of food and nutritional security. A central theme to guaranteeing small-scale fisheries contribution to sustainable food and nutritional security in Nigeria is addressing post-harvest losses (PHL). Considerable fish loss occurs between production and consumption. A narrative review was conducted to expose PHL practiced by SSF and discuss factors that prevent the adoption of locally available interventions. Our study revealed that sun-drying and smoking are the major interventions practiced to mitigate PHL. Unfortunately, these methods of reducing PHL are constrained by gross under-capacity and improper
TBTI has published a photo e-book on The meaning of small: Diverse values of small-scale fisheries. This volume is coordinated by TBTI the TBTI Diverse SSF Values research cluster, which advocates for better understanding and enhanced knowledge about the importance of small-scale fisheries and their various contributions to society. Through the study of values, we gain appreciation for what matters to the people and what is desirable to society. Further, understanding what these values are, how they differ between different regions, and how they influence decisions can lead to better natural resource arrangements.. TBTI aims to portray this plethora of core values through the e-book publication by using visual stimuli such as infographics and photos to convey what small-scale fisheries mean in particular places. We developed a rapid assessment survey to help capture the range of values, based on the scheme suggested by Song and Chuenpagdee (2015).. Click here to see the publication.. How ...

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
This research aims to determine the socio-economic contribution of small-scale fisheries in British Columbia. In order to do so, a definition of small-scale fisheries is needed, as there is currently no national working definition of this sector in Canada. First, we apply three approaches presented in the literature to split British Columbias fishing fleets into small- and large-scale sectors. Second, we overlap the results from the three approaches to categorize BCs fisheries into small- and large-scale. Third, we evaluate the socio-economic contribution of small- and large-scale fisheries identified by the three approaches. We show that many of British Columbias fisheries can be classified as small-scale. From these analyses, we also demonstrate that the small-scale sector receives a higher average price per pound of landed catch than the large-scale sector. However, the large-scale sector consumes less fuel per tonne of landed catch than small-scale fisheries, which does not fit with the ...
Seabird mortality in fisheries is a global problem and a major driver of the continued decline of many seabird populations. Unless appropriate mitigation is in place, longline fishing can cause high levels of seabird mortality. Here we describe the development and implementation of seabird mitigation measures in the Patagonian toothfish Dissostichus eleginoides fishery around the sub-Antarctic islands of South Georgia (CCAMLR Subarea 48.3), since the fishery began in the late 1980s. The initial high bycatch mortality (,5000 birds / 0.59 birds per 1000 hooks in 1996) has been reduced to negligible levels (,0.01 per 1000 hooks) through implementation of a suite of mitigation measures and a high level of compliance. The principal species killed in the fishery were black-browed albatross and white-chinned petrels, with most of the mortality occurring in April and early May. Whilst the synchronous introduction of much of the mitigation makes it is difficult to confirm which measures have been most ...
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
The annual fishery in Israels southern Galilee is set to be reduced in March because of the ongoing conflict in Gaza, according to the Israel Fisheries Authority.. The ministry of fisheries said on Friday that the annual fishing quota for the year, which is usually about 6.5 million fish, would be reduced from 15 million to 9 million.. The quota was set to fall by 2 million fish by mid-March, but only by one-third.. The fishermens union, the Association of Fishermen of Israel (AFI), said that fishermen were still catching up on their catch.. The Association of Israeli Fishermens Associations (AIFA), which represents the countrys fishery operators, said that it is working with fisheries management bodies to reach an agreement on the reduction of the quota in order to ensure that fishers do not lose their livelihoods in the ongoing blockade on the Gaza Strip.. Israel has been locked in an escalating blockade on Gaza for more than a year, imposed following Hamas takeover of the territory in ...
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,
Today, the National Fish and Wildlife Foundation (NFWF), a partner of the NOAA Marine Debris Program, announced four grants totaling $643,000 to support activities in Alaska, Florida, Maine, and Washington to reduce the amount of derelict fishing gear in the marine environment. The grantees will leverage an additional $226,000 in matching contributions, with a total of $870,000 dedicated for this work.. Derelict fishing gear is fishing gear that is lost, abandoned, or discarded in the marine environment, and includes lines, nets, pots, traps, floats, and other gear. Once lost or discarded in the ocean or Great Lakes, gear can continue to trap and kill fish, crustaceans, marine mammals, sea turtles, and seabirds, also known as ghost fishing.. The grants announced today are provided through the Fishing for Energy Grants Program, a partnership between NOAA, NFWF, Covanta, and Schnitzer Steel Industries that began in 2008 to promote proper disposal of old, unusable, and derelict fishing gear. The ...
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 ...

The shrimp fishery is the most economically important in Sinaloa, and the shrimp fishing season occurs from September to March. Since the early 1960s, the Sinaloa shrimp fishery has been closed from April through August. Small-scale fisheries generally use fiberglass skiffs known as pangas to catch shrimp. Managers report that the Gulf of California harbors about 29,000 pangas officially registered for small-scale fisheries, 82% of which are found in the northwest Mexican Pacific coast, including Sinaloa with ~11,000 of these pangas. Producers in the northern region use both trawl nets and gillnets to target blue shrimp.. According to managers, the shrimp resource has been at its maximum sustainable yield in recent years. Current management strategy is composed of a series of measures that include: closed seasons (normally between April and August), designated fishing areas, and restrictions on gear. These management practices as a whole are designed to maintain the reproductive biomass and ...

Many of the worlds fisheries are unassessed, with little information about population status or risk of overfishing. Unassessed fisheries are particularly predominant in developing countries and in small-scale fisheries, where they are important for food security. Several catch-only methods based on time series of fishery catch and commonly available life-history traits have been developed to estimate stock status (defined as biomass relative to biomass at maximum sustainable yield: B/B-MSY). While their stock status performance has been extensively studied, performance of catch-only models as a management tool is unknown. We evaluated the extent to which a superensemble of three prominent catch-only models can provide a reliable basis for fisheries management and how performance compares across management strategies that control catch or fishing effort. We used a management strategy evaluation framework to determine whether a superensemble of catch-only models can reliably inform harvest ...
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 ...

The hilsa shad (Tenualosa ilisha) fishery is by far the largest single species fishery in Bangladesh. In this paper, a simple bio-economic year-class based model is developed to describe the fishery and examine its properties. With the help of this model, the optimum sustainable yield of the fishery is calculated and compared to the existing situation. In addition, the model is used to locate a socially and economically reasonable dynamic path from the current situation to the optimal one. The results indicate that the fishing effort (measured in standardised boat units) required to make the hilsa fishery attain sustainable maximum economic benefits is about one-third of the current fishing effort. At this sustainable fishing effort level, annual net economic benefits from the fishery would be worth about US $260 million according to my calculations compared to virtually nothing today. The present value of the fishery along a moderate effort adjustment path to this long-term equilibrium position ...

Consolidation of the fishing industry worldwide is an issue heavily debated among scholars. Many economists have argued for its necessity, while others - such as sociologists, anthropologists and geographers - have pointed out negative effects of consolidation on fishing communities. The aim of this paper is to measure the geographical consolidation of fishing in Iceland since the introduction of the quota management system in 1984, and during its development into an individual transferable quota system (ITQ). Lorenz curves, Gini calculations and maps are used for this purpose. Consolidation of the fishing sector is a logical outcome of ITQs and the analysis shows that the ITQ system has led to increased geographical consolidation in the demersal and pelagic sectors in Iceland. Regions and communities are unequally affected by geographical consolidation and many small fishing communities are vulnerable to changes in the industry. The results are of value for fisheries management policy ...
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
South Africas marine resources are essentially fully exploited and in some cases over exploited. The Government of National Unity has embarked on the ambitious Reconstruction and Development Programme (RDP) to meet the basic needs, develop the countrys human resources, build economy, and democratize the state and society. Although fisheries can only be expected to play a minor role in contributing to RDP, the Programme have a role to play in managing South Africas living marine resources. The role of RDP in fisheries management is presented together with fisheries management approaches to help achieve the aims of the RDP.
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 ...
The paper describes the wide range of traditional fishing gear used by subsistence and professional fishers in the inland waters in Bangladesh as well as their impact on the fisheries and the environment. The negative impacts indicate the need for regulation of specific types of fishing gear at particular times of the year. An awareness/training program should be extended to the fishermen to create awareness of the long-term effects of their fishing practices and to impart knowledge of fishing laws ...
State of Odisha is bestowed with Inland, Brackish Water and Marine resources and the Fisheries activity is prominent in the State. Marine and Inland fisheries sectors offer a vast scope for development and investment in a number of projects. Along with various Centrally Sponsored Schemes and Centrally Plan Schemes, the State Government on its own has initiated various activities for welfare of fishermen as well as increasing the fish production of the State. The plan, programme and policies of Fisheries Sector are carried out through the Directorate of Fisheries, Odisha. The Directorate of Fisheries, Odisha was created in the year 1956 to look after all-round development of Fisheries activities in the State. It is basically a service sector and extension oriented technical Department, which promotes scientific aquaculture in the state and look after the welfare of Fisher folk.. Livestock products account for more than 20 % of the total value of agricultural output. Livestock production, ...

The following tables represent effort, retained catch (kept) and discard as reported on longline Log sheets for the American Samoa limited-access longline fishery. Effort and catch-effort statistics are based on date of longline haul. Effort and catch statistics are based on logbook data submitted to the PIFSC, FRMD and represent an Oracle table LLDS_REPORT_STATS_AS database extraction done on 21 June 2016. When a statistic (number of vessels, trips) can involve dates of haul in 2 summary periods (i.e. years, semi-annual, quarters) the item is counted in both summary periods. Thus, a trip total is for partial and completed trips. As such, these are not additive statistics (i.e. sum of 4 quarters is not the total for the year, etc).

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 ...
Bert Deener, of the Georgia Fisheries Division was the guest speaker at a recent meeting of the Exchange Club of Waycross. They have authority over thirty-four counties in the region. It covers a five-to six county-wide strip along the eastern coast of Georgia from Florida to South Carolina line. Georgia holds world-wide record for bass and chain pickeral. Commercial fisheries fair well in high water fishing of blue gill and red eye fish. The Altamaha is excellent for fishing and holds world record for blue gill and red eye fish. Flathead catfish are big in the Altamaha River. There are four fisheries in the North Georgia area. Crappie is good fishing now. Some get to ten pounds. The Division has placed 100 brush piles in the rivers for fish. Night fishing will start February 18. They started in 1996 to remove flatheads from the rivers. High water and flood areas are goof for fishing.. ...
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 ...

There is now evidence that in recent years, growth in cephalopod landings has declined. The ...
My basic and technical education were obtained in public schools. My postdoc research project was on reproduction and ecology of fishes captured by small-scale coral reef fishery in the northeast Region, Brazil. I obtained my PhD in Oceanography at the Institute of Oceanography of the University of São Paulo, Brazil, in 2015. Part of my PhD research was carried out in AZTi Tecnalia (Marine Research Division), Spain. I participate as member of editorial board and reviewer of national and international scientific journals. I also have scientific articles, book chapters and abstracts published by national and international publishers, participation in oceanographic cruises and didactic experience teaching undergraduate and postgraduate students. I have been focused on biological oceanography with emphasis on fishery resources; fishery assessment and management; fish biology and ecology; fisheries socio-economic impact and artisanal/subsistence fisheries.. ...
Temperature controls important physiological processes in fish and determines aspects of their niches. In an effort to inform selective fishing and spatiotemporal management in the U.S. Northeast Multispecies fishery, we used 16 years of data from the Northeast Fisheries Science Center Spring and Fall Scientific Trawl Surveys to determine if bottom temperature can be used to differentiate the distribution of Atlantic cod (Gadus morhua) from other species within the fishery management plan (FMP). We identified two separate regimes in spring temperatures and used empirical cumulative distribution functions to calculate biomass availability by temperature for each species. We applied a bagged approach to find optimum thermal threshold values that maximize the difference in cod biomass from each of the other species. For our study area, 38% to 54% of the species considered were well separated from cod by temperature in spring, whereas only 17% were separable in the fall. This study suggests that ...
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 ...

Canada (Attorney General), [2004] F.C.J. No 1762, Federal Court, October 20, 2004, OKeefe J.. Decker was a core enterprise fisher in Newfoundland and Labrador holding a groundfish licence. In April of 1997, the Department of Fisheries and Oceans (DFO) announced that the total allowable catch for northern shrimp would be increased for 1998, subject to resource stability. Temporary permits would be issued for 1998 to allow new entry into the shrimp fishery. To qualify for a temporary permit, fishers had to be geared up and inspected by DFO before the end of 1998.. Although the DFO policy indicated that to get a permit in 1998 a vessel had to be fully geared up and ready to fish shrimp at the time of the inspection, Decker contended that he was told that if he acquired all of the necessary gear and had it on his property ...

Oral History of Edward J. Crateau interviewed by: Jerry C. Grover September 21, 2009 ABSTRACT: Ed Crateau was a career Fishery Management Biologist in the Fishery Resources Program of the U.S. Fish & Wildlife Service from 1967 until his retirement in March 2000. The early portion of his career was in the National Fish Hatchery System but opportunity led him to Alaska for assignment in Fishery Management that he followed for the remainder of his career. He was one of only a handful of biologists in the Fisheries program to be a pilot. His work with the Gulf-Coast race of striped bass and Gulf sturgeon on the Apalachicola River in Florida provided break through information in the management of these species and his extensive work as the Project Leader for the Lower Snake River Plan office in Boise, Idaho was innovative and set the course for the extensive fish marking and evaluation of project operations.

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 ...
CPW is responsible for the preservation and protection of native and non-native wild trout populations. Most mountain streams and some high lakes in Colorado support populations of wild trout. These resources are important to the integrity of Colorados trout fisheries; as an indicator of properly functioning aquatic ecosystems; and for their intrinsic value to those seeking a unique, aesthetic and significant fishery resource. to assure the continuation and availability of wild self-sustaining trout populations the Parks and Wildlife Commission has established specific management guidelines for those aquatic habitats which support all life stages of trout. These waters are to be managed to the extent possible to maintain these wild trout populations.. ...

Feeling the candy brisk fall breeze being out in the open waters is what each man goals of. The first forged, the first fish, the first odor of touchdown that gigantic northern pike. There are many walleye within the lake with many trophy-sized fish, but the extremely heavy fishing pressure right here makes it tough to land more than a couple of fish per outing and a few anglers that fish out here by no means catch a walleye. The beautiful beaches and water recreation are enough to make you want to go to, but the fishermen produce other reasons for wanting to come here.. A very good fishing rod for ice fishing is short and really strong to be sure that it could actually take the strain and weight of the fish. There are even some representations that trace in the direction of fishing being pursued as a pastime.

Marine fisheries within the France (Channel) England region support approximately 4000 vessels, 27% of the UK and 28% of the French fishing fleets. The regions also host many fishery-dependent communities, with significant input to the local economy and employment rates.. Under current EU policies, including ones set to be drafted into UK legislation, France and England seek to improve sustainable management of marine resources and to build resilience in the face of climate change and increased human activity within these waters.. FISH INTEL will use innovative underwater tracking technology to build a comprehensive picture of fish movements and the habitats individual species prefer.. It will also contribute to a growing amount of data assessing the impact of fishing, climate change and other human activities - such as the development of offshore renewable energy sites and offshore mariculture in the Channel region.. Ultimately, it is hoped the data and research gathered through this project ...

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 ...
In Canada, the silverside fishery is concentrated in Prince Edward Island with low and occasional landings reported from Quebec. The Canadian reported landings between 2000 and 2008 varied between 200 and 650 t, and represented 98% of the total commercial fishery landings for the species in eastern North America.. The PEI silverside fishery showed peak reported landings in the late 1970s, was low in the 1980s and the early 1990s, and began a sharply rising trend in the mid-1990s (Figure 2). The increase in landings coincides with an increased number of licences and the elimination of individual licence quotas. Silverside fisheries are concentrated in Kings County in eastern PEI with 86.6% of total landings since 1973. At the present time, an unknown but likely major part of silverside harvest may be kept for the fishers own use, or sold to other fishers. In either case, the harvest may be unregistered in the statistics system.. The modern silverside fishery began in PEI in 1973, first with ...

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 ...
