Fishery management programs designed to control Pacific salmon (Oncorhynchus spp.) for optimum production have failed to prevent widespread fish population decline and have caused greater uncertainty for salmon, their ecosystems, and the people who depend upon them. In this special feature introduction, we explore several key attributes of ecosystem resilience that have been overlooked by traditional salmon management approaches. The dynamics of salmon ecosystems involve social&amp;#8211;ecological interactions across multiple scales that create difficult mismatches with the many jurisdictions that manage fisheries and other natural resources. Of particular importance to ecosystem resilience are large-scale shifts in oceanic and climatic regimes or in...

Resilient Salmon, Resilient Fisheries for British Columbia, Canada
Provedor de dados: Ecology and Society
Autores: Healey, Michael C; University of British Columbia; CALFED Bay-Delta Program; healey@interchange.ubc.ca.
Salmon are inherently resilient species. However, this resiliency has been undermined in British Columbia by a century of centralized, command-and-control management focused initially on maximizing yield and, more recently, on economic efficiency. Community and cultural resiliency have also been undermined, especially by the recent emphasis on economic efficiency, which has concentrated access in the hands of a few and has disenfranchised fishery-dependent communities. Recent declines in both salmon stocks and salmon prices have revealed the systemic failure of the current management system. If salmon and their fisheries are to become viable again, radically new management policies are needed. For the salmon species, the emphasis must shift from maximizing...

Changing U.S. Ocean Policy Can Set a New Direction for Marine Resource Management
Provedor de dados: Ecology and Society
Autores: Rosenberg, Andrew A.; University of New Hampshire; andy.rosenberg@unh.edu.
A central concept in a new direction for ocean policy in the United States is ecosystem-based management, that is, implementation of management integrated across sectors of human activity to achieve the common goal of conserving the structure and function of marine ecosystems to provide a full suite of ecosystem services. Fisheries are a critical sector of ocean activity that impacts these ecosystems, and fishery management is in urgent need of reform to perform better from a conservation perspective. Here, I suggest some specific changes in perspective for fishery management as part of an overall ecosystem-based approach.

Autores: Rey-valette, H; Martins, P.
A new programme concerning the experimentation of about thirty Fish Aggregating Devices (FADs) is to start in the Cape Verde Islands at the end of 1999. In this context, this communication is intended: - to evaluate the halieutic, economic and social conditions of the artisanal fishery in this archipelago, notably in terms of assets and constraints. Although these conditions are very heterogeneous depending on islands, the fads seem to be able to help the stabilization and the development of the fishing activities, disadvantaged by a low productivity, limited operating ranges of boats, and very irregular outings at sea. But the narrowness of the domestic market is likely to cause drops in the fish prices if the production increases, while the absence of...

Using the ALADYM simulation model for exploring the effects of management scenarios on fish population metrics
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Spedicato, Maria Teresa; Poulard, Jean-charles; Politou, Chrissi-yianna; Radtke, Krzysztof; Lembo, Giuseppe; Petitgas, Pierre.
Simulation of fisheries systems is a widely used approach that integrates monitoring and assessment tools. We applied the ALADYM (age-length based dynamic model) simulation model to three different studies aimed at investigating correlations between pressure and population metrics, exploring the viability of different mortality levels in long-term scenarios and predicting the effects of combined management measures. Uncertainty was incorporated into the simulations following the Monte Carlo paradigm. Three stocks were used for these exercises: red mullet in the central-southern Tyrrhenian Sea and European hake in both the Bay of Biscay and the Aegean Sea. The analysis of the relationships between total mortality and indicators highlighted significant...

Marine turtle interaction with purse-seine fishery in the Atlantic and Indian oceans: Lessons for management
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bourjea, Jerome; Clermont, Sandra; Delgado, Alicia; Murua, Hilario; Ruiz, Jon; Ciccione, Stephane; Chavance, Pierre.
Bycatch of endangered marine turtles is a growing issue for the management of all fisheries, including the oceanic purse-seine fishery. The aim of this study was to assess the spatial and temporal variation in bycatch rates of these species in the entire European purse-seine fishery operating in the Atlantic and Indian oceans. The study was based on data collected through observer programs from 1995 to 2011. During that period, a total of 15 913 fishing sets were observed, including 6 515 on Drifting Fish Aggregating Devices (DFADs) and 9 398 on free swimming schools, representing a global coverage of 10.3% and 5.1% of the total fishing activity in the Atlantic and Indian Ocean, respectively. Moreover, from 2003 to 2011, 14 124 specific observations were...

Etat de la Peche des Sparides du Golfe du Lion. Application de Deux Modeles de Gestion (Schaefer, 1957; Beverton et Holt, 1957) aux Stocks de Pagellus erythrinus et Boops boops.
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
In the Gulf of Lion, only three species of Sparidae present a true economical interest : The pandora, the bogue and the gilt head bream. They totalize 90% of the catches of this family. The model of Schaefer is inapplicable to the pandora and bogue stocks and the author could not determine an optimal fishing effort for these two species. The important heterogeneity of size and equipment of the trawlers and the notable imprecision of the fishery statistics explain, perhaps, the inadequacies of this logistic model to this fishing. The author has defined the potentialities of the production of the pandora and bogue stock using the analytical model of Beverton and Holt. He verifies that an increase of the yield corresponds to a decrease of the fishing effort....

Five critical questions of scale for the coastal zone

Autores: Swaney, D. P.; Humborg, C.; Emeis, K.; Kannen, A.; Silvert, W.; Tett, P.; Pastres, R.; Solidoro, C.; Yamamuro, M.; Henocque, Yves; Nicholls, R.
Social and ecological systems around the world are becoming increasingly globalized. From the standpoint of understanding coastal ecosystem behavior, system boundaries are not sufficient to define causes of change. A flutter in the stock market in Tokyo or Hong Kong can affect salmon producers in Norway or farmers in Togo. The globalization of opportunistic species and the disempowerment of people trying to manage their own affairs on a local scale seem to coincide with the globalization of trade. Human-accelerated environmental change, including climate change, can exacerbate this sense of disenfranchisement. The structure and functioning of coastal ecosystems have been developed over thousands of years subject to environmental forces and constraints...

Impact des mesures de gestion sur la dynamique de la pêcherie pélagique du golfe de Gascogne : Quelles certitudes ? Quels descripteurs ?
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lehuta, Sigrid.
Quantitative evaluations of management measure impact on resource and fleet viability are required to provide diagnostics and feed decision process. Fisheries are complex systems where numerous dynamics interact at various spatial and temporal scales. This complexity and the difficulty to observe marine systems are responsible for the high uncertainty surrounding fishery functioning that makes it hard to identify adequate management measures. The increasing consideration of uncertainties in diagnostics argues in favor of robust management measures rather than optimal management measures. Identifying robust management measures requires the development of models that account for complexity and uncertainty in the description and prediction of management...

Bioeconomic model of the dynamics of fisheries facing global economic and environment changes: the French Guyana shrimp fishery
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Chaboud, Christian; Thebaud, Olivier.
In the past two decades, the French Guyana shrimp fishery has known dramatic evolutions, largely driven by global changes. On the economic side, two major driving factors are the globalization of the shrimp market, with a decreasing trend in real prices, an d the long-term increase in fuel prices worldwide. On the environmental side, recruitment of the two main species of shrimp targeted in the fishery seems to have decreased over the last decade. This decrease is probably related to hydroclimatic modifications linked to global change. It is important to assess the adaptive capacity of the fishery facing such changes, as well as the relevance of past and future public policies to improve this capacity.  A key component of this adaptive capacity is the way...

An evaluation of the policy of fishery resources management by TACs in European Community waters from 1983 to 1992
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Biais, Gerard.
In 1983, the European Community (EC) agreed on a system for the conservation and management of fishery resources whi h is based largely on the use of annual total allowable catch (TAC). Nevertheless, the state of many European stocks of demersal species has worsened since 1983. A review of TAC enforcement shows that landings have exceeded TACs to a limited estent for these resources. The contrary is observed for the stocks of pelagic species of which the state has improved although landings have frequently been larger than TACs. This double paradox generates a feeling of limited impact of the TAC system inmplemented by the EC. To investigate the reasons, the closeness between agreed TACs and scientific recommendations has been examined. The results show...

Autores: Santarelli, L; Gros, Philippe.
The totality of French landings of whelk (Buccinum undatum L.) is assignable to the fisheries of the Normand-Breton Gulf, western Channel. The aim of this paper is to forecast economic rent of the potters of the harbour of Granville, as a function of the two main variates open to supervision: the size of the fishing fleet, and the number of whelk-pots per ship. In order to assess the biological and financial consequences of a prospective development, a deterministic model of the fleet-resource system is proposed. Results of simulations emphasize the sharpness of the rent-dissipation problem under existing tendencies. Therefore some recommendations are put forward to derive a fishery policy that would enable the system to be maintained near optimal...

Guam Fish Aggregating Device programme
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Torres, A.
Installation and maintenance of FADs by the Government of Guam began in 1979, initially with funding from the Salstonstall-Kennedy Act through the Pacific Tuna Development Foundation. Current funding for the Guam FAD project is provided through the Dingell-Johnson/Wallop-Breaux Sport Fish Restoration programme, a Federal Aid Project funded by taxes collected on the purchase of fishing equipment and motorboat fuels nationwide. There are now sixteen operational FAD sites in Guam's waters. At a cost of approximately US$10,000 per system, concern for the rising costs of replacing and maintaining FAD systems has prompted the Department of Agriculture's Division of Aquatic and Wildlife Resources (DAWR) to investigate alternative FAD maintenance strategies and...

The potential impact of marine protected areas on the Senegalese sardinella fishery
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ba, Aliou; Chaboud, Christian; Schmidt, Joern; Diouf, Malick; Fall, Massal; Deme, Moustapha; Brehmer, Patrice.
In the early 2000s, Senegal set up several Marine Protected Areas (MPAs) along its coastal zone with the purpose of biodiversity conservation and to support sustainable management of fisheries. However, the impact of MPAs may vary according to the type of fisheries. In Senegal, the sardinella fishery accounts for 70% of total catches. This fishery is of crucial importance for national food security and employment. Given this importance, it is necessary to evaluate the impact of MPAs, often being considered as a tool for fisheries management. An analytical, dynamic and spatial bio-economic model of sardinella fishery, considering fish and fisher migration, has been developed and scenarios over forty years have been analyzed. The results show that the...

Autores: Dunn, M. R.; Rogers, S. I.; Morizur, Yvon; Tetard, Alain; Aublet, B; Le Niliot, Ph; Miossec, Dominique.
The objective of this study was to develop an effective biological sampling programme for fish species in the English Channel (ICES Divisions Vild and Vile) which are not subject to quota management, and to prepare these data for use in multispecies, multi-fleet models being developed by the Channel Fisheries Study Group. Length and age data were coIlected for six non-quota species, and length data for a further five species. The samples were coIlected over a period of two years from important ports on the French and UK coasts. The exploitation patterns of each species were described by allocating catches from similar catching gears, regions, seasons and target species into common units referred to as métiers. The most important métiers in terms of landed...

What is behind fleet evolution: a framework for flow analysis and application to the French Atlantic fleet
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Quillérou, Emmanuelle; Guyader, Olivier.
The study of fishery dynamics considers national-level fleet evolution. It has, however, failed to consider the flows behind fleet evolution as well as the impact of the dynamics of owners of invested capital on fleet evolution. This paper establishes a general conceptual framework which identifies different vessel and owner flows behind fleet evolution and some relationships between these flows. This descriptive conceptual framework aims to change the current focus on drivers of fleet evolution to drivers of the flows behind fleet evolution. We identify a direct impact of vessel flows on the fleet size and nature, and an indirect impact of the movements of capital owners on the fleet evolution (size and nature). This conceptual framework is illustrated...

A model for the phenotypic plasticity of North sea herring growth in relation to trophic conditions
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Shinn, Yunne-jai; Rochet, Marie-joelle.
An adaptation of the von Bertalanffy growth model is formulated to describe the phenotypic plasticity of fish somatic growth in relation to trophic conditions. The model is developed for the North sea Downs herring (Clupea harengus). II suggests that annual growth variability during 1974-1990 was mainly due to the combined effects of herring abundance and wind-induced turbulence (coincident with the spring stratification of the water column). Springtime turbulences cause reduced and delayed planktonic blooms preceding the annual foraging period of Downs herring. The negative relation observed between herring abundance and growth is hypothesized to be due to intra-specific competition for trophic resources. Incorporated into the calculation of yield per...

An Impact Assessment (IA) is a process aimed at structuring and supporting the development of policies. Besides the fact that IA assumes different features when applied to different sectors, really it should help policy makers in evaluating the contribution to the fisheries sustainability of new regulations. The recent improvements and development around the IA methodologies go more and more toward the concept of a Sustainability Impact Assessment (SIA). The evolution of IA in the fishery sector has followed the general and increasing need in having a more and more integrated type of analysis, focusing on the three dimensions of sustainability (environmental, economic and social).

A new approach to determine the distributional effects of quota management in fisheries
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bellanger, Manuel; Macher, Claire; Guyader, Olivier.
Quota allocation mechanisms have distributional effects that are highly relevant to the economic organization of fisheries. In France, where fishing allocations are non-transferable, quotas are shared among Producer Organizations (POs) based on the historical landings of their members. Each PO is then responsible for implementing their own internal rules that provide individual or collective allocations to their members. This study investigates the distributional effects of the various quota management systems adopted by POs on quotas and production for the Bay of Biscay sole fishery. A comparison between initial allocations by vessel based on historical landings and actual observed landings is presented. Inequality metrics are used to quantify...

Autores: Berthou, Patrick; Chevaillier, P; Jezequel, Michele.
Introduction: Setting up a policy of coastal fisheries management goes through a preliminary stage of understanding the dynamics of the fishing fleets as much as their tactics.  Small fleets, such as those of the Côtes d'Armor, are characterised by: - the boats' home ports are scattered widely, - the heterogeneousness of the types of vessels and fishing gear used,  - the versatility of the fishing units, - the plurispecificity of the exploited resource, - the flexibility of operating strategies, that is, the fishing owners' ability to change occupation. However, this flexibility is limited by the availability of the resource, by the market, by the investments granted (boats, fishing materiel), as well as by "cultural" context and know-how.   This...

The Risky Decrease of Fishing Reference Points Under Climate Change
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Travers-trolet, Morgane; Bourdaud, Pierre; Genu, Mathieu; Velez, Laure; Vermard, Youen.
In Europe, implementation of sustainable fisheries management has been reinforced in the latest common fisheries policy, and presently marine fish stocks are mostly managed through assessment of their exploitation and ecological status compared to reference points such as Maximum Sustainable Yield (MSY). However, MSY and its associated fishing mortality rate FMSY are sensitive to both stock characteristics and environment conditions. In parallel, climate change impacts are increasingly affecting fish stocks directly and indirectly but might also change the exploitation reference points and the associated level of catch. Here we explored the variability of MSY reference points under climate change by using a multi-species model applied to the Eastern...

A model-based evaluation of Marine Protected Areas: the example of eastern Baltic cod (Gadus morhua callarias L.)

Autores: Kraus, Gerd; Pelletier, Dominique; Dubreuil, Julien; Moellmann, Christian; Hinrichsen, Hans-harald; Bastardie, Francois; Vermard, Youen; Mahevas, Stephanie.
The eastern Baltic cod stock collapsed as a consequence of climate-driven adverse hydrographic conditions and over fishing and has remained at historically low levels. Spatio-temporal fishing closures [Marine Protected Areas (MPAs)] have been implemented since 1995, to protect and restore the spawning stock. However, no signs of recovery have been observed yet, either suggesting that MPAs are an inappropriate management measure or pointing towards suboptimal closure design. We used the spatially explicit fishery simulation model ISIS-Fish to evaluate proposed and implemented fishery closures, combining an age-structured population module with a multifleet exploitation module and a management module in a single model environment. The model is parameterized...

Autores: Nicolle, Amandine; Moitie, Roderic; Ogor, Julien; Dumas, Franck; Foveau, Aurelie; Foucher, Eric; Thiebaut, Eric.
The great scallop Pecten maximus supports one of the most important and valuable commercial fisheries around the British Isles and in the northwest of France, but the resource is mainly managed at the scale of each local fishing ground through a combination of European, national and local measures. To analyse the larval dispersal pathways and connectivity patterns among fishing grounds of the great scallop in the Celtic Sea and the English Channel, a particle tracking model was developed. The model combined a 3D physical circulation model that simulated currents and temperature fields and a scallop larval submodel that took into account a temperature-dependent planktonic larval duration and an active vertical swimming behaviour. Due to the lack of stock...

Migration is a ubiquitous life history trait with profound evolutionary and ecological consequences. Recent developments in telemetry and genomics, when combined, can bring significant insights on the migratory ecology of non-model organisms in the wild. Here, we used this integrative approach to document dispersal, gene flow and potential for local adaptation in anadromous Arctic Char from six rivers in the Canadian Arctic. Acoustic telemetry data from 124 tracked individuals indicated asymmetric dispersal, with a large proportion of fish (72%) tagged in three different rivers migrating up the same short river in the fall. Population genomics data from 6,136 SNP markers revealed weak, albeit significant, population differentiation (average pairwise FST =...

Assessment of condition in pejerrey Odontesthes bonariensis (Atheriniformes: Atherinopsidae) populations: which index works best?
Provedor de dados: Neotropical Ichthyology
Autores: Baigún,Claudio R. M.; Colautti,Darío C.; Grosman,Fabian.
The pejerrey Odontesthes bonariensis is the most important target species in temperate freshwater fisheries of Argentina, and assessment of condition has been a regular practice and common diagnostic tool. Most pejerrey fishery studies have used Fulton's (K) index, without testing whether underlying assumptions or requirements were met. We analyzed and contrasted the applicability of K, Kn and Wr indices to assess condition status in several pejerrey populations inhabiting Pampean lakes. Our results showed that whereas Wr and Kn displayed significant condition changes across length at some study lakes, Kn portrayed a small range of variation. We also noted that pejerrey maximum length and size structure strongly varied among populations probably due to the...

Fishing resources in the rio Cuiabá basin, Pantanal do Mato Grosso, Brazil
Provedor de dados: Neotropical Ichthyology
Autores: Mateus,Lúcia. A. F.; Penha,Jerry M. F.; Petrere,Miguel.
The rio Cuiabá is one of the most important tributaries of the upper rio Paraguay basin that form the Pantanal wetlands. The fishing resources of the rio Cuiabá basin were studied based on landing data obtained from the Fish Market of the city of Cuiabá, State of Mato grosso, Brazil. A description is given of the composition and origin of the 2000 and 2001 catch. The rio Cuiabá is the main source of fish for Cuiabá, although some fish sold locally comes from the rio Paraguay. The 2000-2001 catch consisted mainly of migratory species. The main landed species were the pimelodids pintado -Pseudoplatystoma corruscans, cachara -Pseudoplatystoma fasciatum, and jaú -Paulicea luetkeni, and the characiforms pacu -Piaractus mesopotamicus, piraputanga -Brycon...

Management proposal based on the timing of oral incubation of eggs and juveniles in the sentinel species Genidens genidens (Siluriformes: Ariidae) in a tropical estuary
Provedor de dados: Neotropical Ichthyology
Autores: Maciel,Thaís Rodrigues; Vaz-dos-Santos,André Martins; Caramaschi,Erica Pellegrini; Vianna,Marcelo.
ABSTRACT Ariids such as Genidens genidens are particularly susceptible to overfishing because of their complex reproductive mechanisms, which result in slow replenishment of stocks. In this study, we obtained data about the reproductive ecology of the catfish G. genidens in the Guanabara Bay estuary, Rio de Janeiro, Brazil, providing supporting information for management of its fishery. The sex ratio, mean size of each sex at first sexual maturation, and female fecundity were determined and the reproductive period was characterized. The males:females ratio was 1:2. The fecundity is low and increases proportionally to the females’ growth in total length and weight. The breeding season occurs during the warmest months of the year, with spawning extending...

Molecular identification of Atlantic goliath grouper Epinephelus itajara (Lichtenstein, 1822) (Perciformes: Epinephelidae) and related commercial species applying multiplex PCR
Provedor de dados: Neotropical Ichthyology
Autores: Damasceno,Júnio S.; Siccha-Ramirez,Raquel; Oliveira,Claudio; Mendonça,Fernando F.; Lima,Arthur C.; Machado,Leonardo F.; Tosta,Vander C.; Farro,Ana Paula C.; Hostim-Silva,Maurício.
ABSTRACT The Atlantic goliath grouper, Epinephelus itajara , is a critically endangered species, threatened by illegal fishing and the destruction of its habitats. A number of other closely related grouper species found in the western Atlantic are also fished intensively. While some countries apply rigorous legislation, illegal harvesting followed by the falsification of fish products, which impedes the correct identification of the species, is a common practice, allowing the catch to be marketed as a different grouper species. In this case, molecular techniques represent an important tool for the monitoring and regulation of fishery practices, and are essential for the forensic identification of a number of different species. In the present study,...

Argentine black drum distributes mainly in shallow waters associated to estuarine areas, particularly to  Samborombon Bay where it may be detected throughout the year. Nevertheless, it can also be spotted more southwards (40°S) and at deeper waters. During summer, catches of the species in Samborombon Bay are practically negligible, probably due to movements towards shallow waters out of reach of the inshore commercial  fleet. Landings increase in autumn and show peak values in winter, coinciding with the fishing season of whitemouth croaker, Micropogonias furnieri, whose geographical distribution within the bay overlaps that of  black drum. As of 1995, landings of black drum showed increasing trends both in Argentina and Uruguay. These increments coincide...

Pour accomplir sa mission, le Ministère chargé de la pêche a mis en place une politique bâtie autour de la gestion durable et rationnelle des ressources halieutiques. Dans le cadre de cette politique, il a été mis en place des instruments sectoriel de gestion (permis de pêche, immatriculation des pirogues, etc.) et une réglementation à travers le cote de la pêche. Malgré la volonté affichée et les moyens déployés par l'administration des pêches, ces instruments de gestion sont difficiles à mettre en œuvre et la réglementation en vigueur est très souvent contournée par les pêcheurs artisanaux dont les aspirations et les logiques sont aux antipodes des préoccupations biologiques à long terme. Dans le cadre de ce travail, nous avons choisi d’étudier les...

Net fishing and its management in Seychelles
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Payet, R.J.
Net fishing is an important component of the artisanal fishery of the Seychelles. It is composed of beach seine, encircling and set gillnets. This report reviews net fishery and its impact on the environment and fish stocks and provides a framework for its management. There are no current management measures for the traditional net fisheries except that all nets above 50 metres requires a license with a lead seal bearing the licence number.  Certain irresponsible uses of these nets have ben acknowledged, principally the 'Met outaz' fishing strategy, incidental catch of marine mammals and the presence of commercially important juvenile fish in the beach seine fishery. SFA has addresses these issues rationally and management options are explored followed by...

Management of shark fisheries in Seychelles
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Nageon de Lestang, J.
Shark species, both oceanic and coastal, are very common to Seychelle waters. In the past, however, the demand for shark and shark products has always been very erratic. The ever-increasing international concern for the species and potential conflicts between fishermen and conservation groups has highlighted the issue. In the Seychelles, the shark are caught by gillnets in inshore waters and by hook-and-line and purse seine offshore. Until very recently there were no regulations controlling the shark fishery, but, partly in response to initiatives by a local conservation group, fishing for sharks with nets has been banned since 1 August 1998. A review is provided of the present situation of the fishery whilst underscoring the difficulties of formulating a...

The present report reviews the spiny lobster fishery on the Mahe Plateau for the 2001/2002 fishing season. The monitoring programme, set up in 1992, was continued this season to collect more information on the spiny lobster stock in order to improve and maintain proper management of this resource around the Mahe Plateau.  For the 2001/2002 lobster fishing season, a total of 40 licenses were issued namely twenty seven on Mahe, five on Praslin and eight on La Digue. Similar to previous seasons, the most frequently used lobster fishing technique was snorkelling which involved 32 fishing units, whilst only four units used the trap method and one used both snorkelling and trap.  For this three-month fishing season, a total of 5.5 tonnes of spiny lobsters were...

The temperature that limits the presence of schools of Argentine chub mackerel Scomber japonicus was found to be around 19°C in the Mar del Plata area Buenos Aires prov., Argentina. At higher values, most shoals leave coastal waters in direction to the mid-shelf. An inverse relationship was observed between catches per unit of effort CPUE and sea surface temperature. The highest CPUE values corresponded to temperatures lower than 19°C. Beyond that value, the possibility of obtaining a CPUE higher than the unit is nearly null and the low standard deviation means it is unlikely to reach high CPUE values. The economic profit per minute of each daily cruise was estimated using a case study carried out with a single vessel pilot with mean structural and...

The fisheries policy of the Republic of Seychelles
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Anon.
The fisheries policy of the Government of Seychelles was first drafted in 1986. At that time, both the industrial and artisanal fisheries in Seychelles were in a developmental stage and the policy reflected the needs to promote both the development and conservation of our marine resources as well as maximizing benefits. In 1985 the number of licenses issued for the industrial tuna fishery was 49 for the purse seiners and 165 for longliners with an annual purse seine catch of 130,000 tonnes. The total catch for the industrial purse seine fishery has continued to rise and peaked at around 407, 000 tonnes in the year 2003. The artisanal fishing fleet has declined from 410 vessels in 1985 to 330 in the year 2003, however, the nature of the fleet has changed...

Resource exploitation in the South Atlantic area shows a general retraction of the distribution range and an isolation of the La Plata River stock where most of the fishing effort concentrates. The species market evolution brought about, for Argentina and Uruguay, an important shift in its dynamics as of 1992, when the product insertion in Asiatic markets generated an important commercial attraction and a subsequent increase in the fishing effort by the argentine inshore coastal fleet. This caused a change in the fishery development in Argentina and the establishment, in winter, of a fleet...

Rapport d'évaluation des Conseils Locaux de Pêche Artisanale (CLPA)
Provedor de dados: Ocean Docs: e-repository of  publications
le Sénégal a adopté une approche participative impliquant tous les acteurs. C’est dans ce cadre que le Sénégal, dans le but d’inverser les tendances encore lourdes de son système de gestion des pêcheries et du développement de son économie halieutique, a opté, entre autres outils d’aménagement, pour la mise en oeuvre d’une approche de cogestion des pêcheries artisanales pour une gestion durable des ressources halieutiques. Le succès, l’extension et la pérennisation de l’approche de cogestion dépendent essentiellement de la fonctionnalité des cadres de concertation mis en place pour assurer l’implication et la participation effective des communautés de base dans les décisions de gestion et d’aménagement. Outre les Comités Locaux de Pêcheurs (CLP) mis en...

Kitefin shark Dalatia licha (Dalatiidae)fishery in the northeastern Atlantic and some recommendations for elasmobranchs explotation
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Perrotta, R.G.
In the Azores Islands (NE Atlantic), between 1986 and 1998, Dalatias licha was caught to obtain liver oil. A drastic abundance decline, probably attributed to a high level of exploitation, was observed. In Argentina elasmobranchs have undergone intensive fishing and, at present, catches are compromised. The history of the fishery in Azores should be taken as example and warning when implementing elasmobranchs fisheries management in Argentina.

The fisheries policy of the Republic of Seychelles
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Anon.
The fisheries policy of the Government of Seychelles was first drafted in 1986. At that time, both the industrial and artisanal fisheries in Seychelles were in a developmental stage and the policy reflected the needs to promote both the development and conservation of our marine resources as well as maximizing benefits. In 1985 the number of licenses issued for the industrial tuna fishery was 49 for the purse seiners and 165 for longliners with an annual purse seine catch of 130,000 tonnes. The total catch for the industrial purse seine fishery has continued to rise and peaked at around 407, 000 tonnes in the year 2003. The artisanal fishing fleet has declined from 410 vessels in 1985 to 330 in the year 2003, however, the nature of the fleet has changed...

Les pêches togolaises contribuant à 4% du PIB du secteur primaire sont exercées sur les plans d’eau maritime, lagunaire, fluviale, barrages et étangs piscicoles. Elles sont artisanales et industrielles en mer et exclusivement artisanales dans les autres pêcheries. Malgré leur relative pauvreté, les ressources halieutiques permettent aux pêcheurs de faire des prises permanentes en mer et en lagune et saisonnières dans les cours d’eau dont les estimations annuelles varient entre 12 000 et 17 000 tonnes. Elles créent environ 22 000 emplois répartis entre 10 000 pêcheurs (60% à temps plein) et 12 000 commerçantes et transformatrices de poissons. Tous ces emplois font vivre directement et indirectement environ 150 000 personnes....

Hoki, Macruronus magellanicus, is an important resource in the Argentinean multispecific southern demersal fishery. The species is distributed South of 46°S between the 50 and 200 meter isobaths. Thesouthern demersal fishery was almost nil prior to 1987, becoming more relevant toward the end of the 1980's. International fleets operating through several fishery agreement were those of the ex-Soviet Union,Bulgaria and Japan. Research on the abundance of hoki resources were initiated in the early 1970's; however, fishery research have been noticeably enhanced since 1992. In this study existing information on the Argentinean hoki fishery is integrated and an assessment of the status of exploitation of the species is carried out.As a result of the analyses, a...

Current fisheries management approaches based on centralised government intervention have proven inadequate to deal with the present management and cannot meet its objectives including reverting stock depletion, resolving user-group conflicts, increase profitability and prevent social disruption. There is no easy solution to this problem. New institutions enabling fishing communities to deal with present pressures are needed. Fisheries management is however still largely government-driven although experiences worldwide show that various forms of partnership between government, industry and fishers strengthen management and produce results. Such partnerships have become known as co-management.

Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Okemwa, E.
A brief review is presented on some of the measures taken to manage Lake Victoria multispecies fisheries. It is suggested that management enforcement is not working. The linkage between research, policy making, industry and artisanal fishery is considered. The paper examines how the whole process of taking management decisions might be modified to take into account the realities of life in the riparian states around the lake and of the complexities and uncertainties of multispecies fisheries. Research and assessment are considered. Understanding the multispecies fisheries and characteristics of contemporary fisheries management are described. Recommendations for future research are given.

Gender plays an important role in the artisanal fisheries, therefore it critical for both men and women to participate fisheries management. This paper analyzes gender responses to introduced or enhanced fisheries regulations and constraints to compliance so as to facilitate gender participation in the management of Lake Victoria in Kenya. Both primary and secondary data have been used. Results indicated that in Lake Victoria, there is a clear-cut division of labor differentiated by gender, which is culturally defined. Men and women respond to management measures differently due to differentiated roles and space they operate in. Poverty emerged as a constraint to both men and women but affecting the women much more due to lack of economic and status...

La pêche occupe une place importante dans l’économie et la société sénégalaises. En effet, elle est une activité multifonctionnelle qui contribue à la fois à l’équilibre de la balance des paiements du Sénégal, à la résorption du chômage et à la satisfaction des besoins alimentaires de la population sénégalaise. Malgré son importance, le secteur de la pêche est confronté à de graves déséquilibres socio-économiques et environnementaux qui résultent de la surexploitation des ressources halieutiques et de l’utilisation de certains modes d’exploitation néfastes. Il en découle des difficultés d’approvisionnement des marchés locaux et une diminution de l’apport en protéine des populations tributaires de la pêche. En outre, la forte propension à l’exportation de...

Autores: Ajayi, T.O.; Adetayo, J.A.
Commercial landings and effort data over the period 1970-1980 as well as shrimp research vessel catches were analysed.  Both shrimp and fish by-catch consistently showed seasonality in abundance. However, while shrimp catches declined from 49.20% of total in 1979 to 13.795 in 1980, incidental fish landings rose proportionately.  The fish shovelled overboard measured 18.0cm or less in total length.  Prominent among these were Brachydeuterus auritus, Ilisha africana and Vomer setapinnis.  The fish discard amounted to 43.68% of the total catch.

The assessment covers hake between 34° and 48°S (Argentina and Uruguay), excluding Golfo San Matías. Total international landings and Argentine catch-at-age and effort data available for the 1983-1991 period allowed an analytical assessment. Tunning of the VPA was made using Laurec-Shepherd analysis and Extended Survivor analysis. The results of these analysis are congruent with the information about the state of the stock. VPA biomass estimates are aound 2.1 and 2.7 mill. Tonnes, which are similar to those calculated through surveys. The Spawning Stock Biomass estimated for 1991 is considered to be within limits where the stock shows stable recruitment. At the present effort level, yield and Spawning Stock Biomass appear to remain stable. Management...

Integrating Anthropogenic and Climatic Factors in the Assessment of the  Caribbean Spiny Lobster (Panulirus argus) in Cuba: Implications for  Fishery Management
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Puga, R.; Piñeiro, R.; Alzugaray, R.; Cobas, L. S.; de León, M. E.; Morales, O.
The Caribbean spiny lobster Panulirus argus, the most valuable Cuban fishery resource, is managed with a set of input  and biological controls. The aim of this study was to integrate  two indices that relates water and nutrients supply and tropical  cyclones activity in the stock assessment, through simultaneous estimation of the parameters of a spawning stock–recruitment  function in a statistical catch-at-age analysis. The population dynamics model allowed estimating key Reference Points for  management at fixed levels of  fishing mortality rate and environmental conditions. The results indicated that the reduction of  recruitment and catches in the Cuban spiny lobster fishery could be a result of synergistic cumulative effects because of the...

Situation de la Pêche en Côte D’Ivoire
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Dadi, S.G.
En Côte d’Ivoire, le secteur halieutique tient une place de choix dans le domaine économique, social et nutritionnel. Le poisson est la première source de protéine animale et sa consommation est de 15 kgs/hab/an. Malgré la faiblesse de la production nationale qui est généralement comprise entre 70 et 100 000 tonnes par an et l’importation de plus de 228 000 tonnes de poisson en 1997, la balance commerciale reste excédentaire de plus de 17 milliards grâce aux exportations de conserves de thon. La pêche constitue cependant un secteur pourvoyeur d’emplois avec environ 70 000 emplois directs et 400 000 emplois indirects. Elle génère près de 48,08 milliards au PIB et compte donc pour 0,80% dans la création de la richesse nationale.

Autores: Wöhler, O.C.; Cordo, H.D.; Hansen, J.E.; Cassia, M.C.
The current status of southern blue whiting Micromesistius australis stock is described. A single, closed fish population is assumed to inhabit the SW Atlantic. Based on catch data corresponding to years 1987-1997, a sequential analysis on the stock is carried out (Cohort Analysis). Under an adaptative framework, catch per unit of effort data from commercial vessels are used to fit the model. Two commercial fleets are used in the fitting, i.e. Polish vessels (1987-1994)and Argentine surimi factory vessels (1991-1997). Results indicate that both, total stock biomass and spawning stock biomass would have declined. Total biomass would have decreased from a maximum close to 1.4 million tons in 1990 down to 0.5 mt in 1997 whereas the current spawning stock...

Distribution of economic benefits from the fisheries of Lake Victoria
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Abila, R.O.; Odongkara, K.O.; Onyango, P.O.
The Lake Victoria fishery contributes immensely to the socio-economic development of the riparian states. The East African Community has designated the lake basin as an ‘economic growth zone’, with the potential to develop into a major economic region. The fisheries are vital in creating employment opportunities, mostly rural-based, thereby helping to reduce rural-urban migration. Fish is also a rich source of animal protein for human consumption and provides raw material (fishmeal) for processing animal feeds. The fish industry contributes to GDP and has continued to be an important source of foreign exchange earned from fish exports. Besides, the fish industry contributes to the national and local government revenues through levying of various taxes,...

Ecosystem Considerations for Managing Marine Fisheries in the Indian Ocean
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Vivekanandan, E.
Fisheries management approach of several countries, including those in the Indian Ocean region, has been generally on a species-to-species basis. It has been realized now that this approach has severe limitations, especially for the tropical, multispecies fisheries. While the understanding that fish and other living aquatic living resources are integral part of their ecosystems is not new, this idea has not been put into practice in managing stocks, especially for the marine fish. Reshaping the management strategies by involving all the stakeholders in such an ecosystem approach is expected to yield short-term and long-term benefits

Le Bénin est caractérisé par un réseau hydrographique assez dense, appartenant à deux grands bassins : le bassin du Niger au nord et le bassin côtier au sud. La côte est sablonneuse rectiligne et s’étend sur 120 km, avec un plateau continental de 3100 km2 chalutable sur 2700 km2. Sa production est estimée à 10300 tonnes en 1998. La pêche continentale est restée peu développée au Nord alors qu’au Sud on a assisté cette dernière décade à une surexploitation significative des plans d’eau en général. La production annuelle est estimée à 30 000 tonnes. Cette surexploitation des plans d’eau du sud Bénin est marquée par une multiplication des pêcheries sédentaires (barrages, parcs acadjas, trous à poissons) et l’utilisation d’engins dévastateurs, indépendamment...

La región monitoreada, fue objeto de captura comercial de cobo en el país. En 1999 se realizó un monitoreo del área que demostró una merma en los niveles de abundancia de la especie, probablemente debido a una sobre- explotación durante 1998, luego de uana moratoria nacional producto de los resultados de Ferrer y Alcolado (1994), así como un mal manejo y desconocimiento de las áreas de concentración. Esto motivó que el Centro de Investigaciones Pesqueras propusiera una veda total, con un plazo indefinido, hasta tanto se evidenciara una recuperación del recurso. Luego de 10 años de reposo, se visitaron las áreas tradicionales de pesca en el año 2009, que demostró que los niveles de abundancia fueron buenos y sobre la base de un manejo precautorio en cuanto...

Autores: Nishida, T.; Komatsu, T.
Strengthening tuna management is one of the primary tasks for the new Indian Ocean Tuna Commission (IOTC). Stock assessment and the prediction of the dynamics of the tuna resources will become increasingly important research topics because they provide the basic information for the management decision process. Under these circumstances, this paper attempts to develop the stock analyses and prediction techniques using neural networks. As a first step and as a test study, analyses and predictions of catch rates of the Japanese yellowfin tuna longline fisheries are attempted.

Autores: Gaamour, A.; Khemiri, S.; Mili, S.; Ben Abdallah, L.
The reproduction parameters necessary for stock management and catch analysis of anchovy in the North region of Tunisia were studied. The global sex-ratio is close to 1, special caution should be taken using this parameter as it is size dependant. Mean reproduction period extends from April to October. However within this period individuals of population have different spawning and maturation. The size at first sexual maturity Lm50 is about 7.3cm. In the North region of Tunisia, the anchovy landings are lower than the exploitable biomass, therefore the anchovy is an under-exploitable species in this region

Knowledge in co-management

Co-management institutions have generally been limited to implementation and have not extended user participation to include the knowledge basis for management decisions. This paper discusses some of the fundamental problems involved if such an extension were to be developed. One set of problems relate to the alienation of the immediate users from the formalised research knowledge which generally is used as the knowledge basis for mainstream modern fisheries management due to the different scales of observation used by formalised research and the immediate resource users and the requirement for predictability which is inherent in many modern management implementations. This set of problems may be reduced through the use of indicators of pressures and state...

The San Matias Gulf (Argentine Sea) fishery was historically developed and based on the catching of a target species: the common hake    Merluccius hubbsi. There are also other marketable species such as the savorin Seriolella porosa. The presence of this species in the gulf is characterized by its abundance, population structure and biology. The material used was derived from three information sources: fishing survey cruises, landing samplings and record of the fishing activity.The results obtained allowed to delimit a spawning ground and a nursery area. The relative abundance of the resource showed seasonal variations with the highest values in August. The captured range size was 19-59 cm for females and 19-56 cm for males. The first sexual maturity was...

Size at sexual maturity was investigated in 346 queen conch, Strombus gigas, collected from the Archipelago of San Andres, Providencia and Santa Catalina (SAI), Colombia. Size at sexual maturity is defined as the size (based on total shell length and lip thickness) at which 50 % of the population of queen conch sampled had mature and emission gonad developmental stages, based on microscopic examination (samples of gonads were processed by standardized histological methods). Only 12.14% of whole samples had mature and emission gonad developmental stages. The size at sexual maturity based on total shell length (STmat) was estimated to be STmat=249 mm for females (n=14), STmat=234 mm for males (n=28) and STmat=241 mm for both sexes (n=42).

Sequential population analysis on Long Tail Hake (Macruronus magellanicus)from the Southwest Atlantic. Years 1985-1995. VPA on the Long Tail Hake (Macruronus magellanicus), based on data covering the years 1985 up to 1995, was performed to assess the current state of the stock. Simulation trials, inducing uncertainty about both the natural mortality rate and recruitment were also accomplished, to evaluate the risk of overfishing which is associated to different fishing alternatives, always under the assumption of a single and closed Long Tail Hake population. CPUE data were not appropriate for tunning, so the traditional VPA has been applied. During the period of study, stock biomass and spawning stock biomass showed an increased trend.

Hake (Merluccius hubbsi) stock assessments and management recommendations made as of 1986 for the Argentine Sea, are summarized. The surplus production models used allowed to diagnose an overdimensioned fleet and to establish that, as of 1983, population densities were lower than the optimum values. In 1990 it was mentioned that total landings exceeded the Maximum Sustainable Yield and that the fishing effort was above the optimum exploitation level. The Virtual Population Analysis was first applied in 1993 and, for the 1986-1991 period, a 25. increase in fishing mortality, significant reductions of total and reproductive biomasses and a first catch length of 25 cm were detected. Besides, proposals were made to enhance accuracy of future assessments. In...

The differential effects of changing management regimes on yields from two fisheries exploiting the same resources
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Djama, Theodore; Pitcher, T.J.
A yield per recruit model has been used to compare the effects of mesh size increment on the yields and revenues of the fisheries of Cameroon under two different cases. Case 1 assumes the commercial fishery to move from the exploitation of three age-groups to two age-groups with no interactions with the artisanal fishery, whereas Case 2 takes into account these interactions. The difference in the percentage increase of yield per recruit between case 1 and case 2 is 61% at current fishing (46% and 18% yield per recruit increment in cases 1 and 2 respectively). The usually accepted long-term yield per recruit increment with increase of age at first capture (with a single non-interacting fisheries) is, in this case, cancelled out. However, the revenues...

Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Narváez-Barandinga, J.C.; Blanco Racedo, J.
The “Coroncoro” fish Micropogonias furnieri has been one of the most important traditional fish resources in CGSM and CP. In order to determine exploitation status of its stock, aspects related to its biology and population parameters have been assessed. Mean maturity size was estimated in 20.7 cm at total length; whereas sex ratio was 2.39 females per male. Ripe individuals occurred throughout the whole year, with a maturation and spawning peak in the rainy season (november). Length-weight relationship showed no difference between sexes and a common equation with allometric growth W = 0.0064LT3.2 was estimated. The estimated parameters of von Bertalanffy growth function were L∞ = 34.0 cm, K = 0.44 yr-1, t0 = 0.301 yr and C = 0.5; with a growth index...

Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Abila, R.O.; Omwega, R.N.; Lwenya, C.
Fishing is known to be one of the oldest occupations of mankind and in Lake Victoria (Kenya); it has been largely practiced at artisanal levels. Despite this, poverty amongst the fisher folk remains high. Why the fisher folk remain in perpetual poverty was the key research question for this study. Sampling was conducted on 12 landing beaches between June and August 2004. Data was obtained using survey questionnaires; personal interviews were made using open-ended questions and beach observations. Results from this study indicates that 179 fishers sampled earned an average income of Ksh. 107,063 each in a year with modal income of Ksh. 57,600 while in a day they earned an average income of Ksh. 518 each with modal income of Ksh. 200. Fishers perceived that...

Period 1987-2001. A diagnosis of the current state of Southern blue whiting (Micromesistius australis) stock in the Southwest Atlantic was carried out on the basis of catches corresponding to the period 1987-2001 as reported by the Argentine fleet and also by vessels operating around Malvinas Islands. Abundance and current fishing mortality rates were estimated, and the biomass evolution in the long term resulting from some possible exploitation strategies based on different management strategies were projected. A sequential population analysis calibrated under a conceptual adjustable framework with five independent abundance indices was carried out. The effects on the biomass estimates were analysed by adopting different selection patterns and calibration...

Management of shark fisheries in Seychelles
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Nageon de Lestang, J.
Shark species, both oceanic and coastal, are very common to Seychelle waters. In the past, however, the demand for shark and shark products has always been very erratic. The ever-increasing international concern for the species and potential conflicts between fishermen and conservation groups has highlighted the issue. In the Seychelles, the shark are caught by gillnets in inshore waters and by hook-and-line and purse seine offshore. Until very recently there were no regulations controlling the shark fishery, but, partly in response to initiatives by a local conservation group, fishing for sharks with nets has been banned since 1 August 1998. A review is provided of the present situation of the fishery whilst underscoring the difficulties of formulating a...

Coral reefs and their management in Tanzania
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Wagner, G.M.
Coral reefs are very important in Tanzania, both ecologically and socio-economically, as major fishing grounds and tourist attractions. Numerous fringing and patch reefs are located along about two-thirds of Tanzania’s coastline. These reefs have been partially to severely degraded by human (primarily destructive fishing practices) and natural (particularly coral bleaching) causes. These immediate human causes have been brought about by various socioeconomic root causes, particularly poverty and lack of proper management. After decades of human and natural impacts there has been only limited reef recovery. This paper presents a region-by-region analysis of trends in the condition of coral reefs in Tanzania in relation to the causes of damage. While earlier...

Period 1985-2001. A stock assessment of Patagonian hoki of the Southwest Atlantic was carried out by using data from the years 1985-2001. A cohort analysis, fitted with some survey abundance indices was used in an adaptive conceptual framework. Simulation trials were performed to project the evolution of the fishery, to evaluate the risk of over-fish the stock under different exploitation levels, and to estimate Biologically Acceptable Catches (BAC). Both total biomass and spawning stock biomass showed increasing trends resulting from four strong year classes (1993, 1995, 1996 and 1998). Total biomass at the beginning of 2001 was estimated to be 2.5 million tons, and spawning stock biomass at the spawning time (August) was estimated to be around 1.28...

On technical viability of the trawler fishery in Nigeria
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Amadi, A.A.; Tobor, J.G.
The concept of technical viability is defined as a combination of factors including fishery resource. Ecology, gear technology, manpower and entrepreneurial skills financial inputs and product markets.  A clear drop in catch per trawler per year in Nigeria is attributed mainly to inadequate cash flow to operate vessels in the face of high fuel costs, lack of spare parts and repair facilities, and some growth over fishing of ground fish stocks.  The transition from artisanal to rapid industrial mechanized fishing has not been matched by the availability of skilled local manpower to effectively operates and service electronic, hydraulic and refrigeration equipment of modern trawlers.  While Nigerian financial institutions have to some extent financed trawler...

A deterministic single-species bioeconomic model is developed in order to provide an integral fishery management. This model is structured by age, in order to simulate the effects of natural and fishing mortalities, with simple economic assumtions. Fishing mortality is estimated through the fishing effort expressed by fishing hours or by HP per fishing hours. Biological underfishing and overfishing are analyzed from the estimated economic equilibrium for period under study.

La langosta común (Panulirus argus) es uno de los principales recursos pesqueros del Caribe  y el más importante de Cuba. Su largo período de duración larval en el océano y las corrientes,  contribuyen con la conectividad de sus poblaciones. Los giros, las contracorrientes y las  migraciones verticales, garantizan los procesos de auto-reclutamiento donde la calidad del  hábitat en áreas de cría, es crucial para el asentamiento de las postlarvas y el reclutamiento de  los juveniles a la pesquería. Los incrementos del nivel del mar, de la temperatura y de la  frecuencia e intensidad de los ciclones tropicales, constituyen las principales amenazas del  cambio climático sobre el éxito del reclutamiento y la conectividad de P. argus.

Since 1995, an experiment on co-management of fisheries has been carried out in the Aby Lagoon (Côte d'Ivoire). The process is based on a consensual definition of the rules of management and the setting up of organizational structures (fishing committees) ready to work with government agencies to achieve common goals. The preliminary results show that fishermen are conscious of their duties. They are available to involve themselves in an active and efficient way. The structure of exchange (communication) created for this purpose ensures satisfying participation of all. The bioeconomic impacts of the co-management can already be seen. Though these positive results are beneficial to the whole community, some fishermen (the owners of beach seines) pay heavy...

This paper addresses the two main problems that Regional Fishery Management Organizations face. First, how to induce independent nations to reduce their fishing efforts from the competitive equilibrium to prevent the fish stock from extinction or to increase profits. We argue that adjustment from the Nash equilibrium to a state of sustainable yield can be achieved by means of the proportional rule without harming any of the countries involved. Next we propose the population monotonic allocation scheme as management rule for the second problem: the division of profits within an

Diagnosis and the management constituency of small-scale fisheries
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Evans,   Louisa; Andrew,   Neil.
Diagnosis and adaptive management can help improve the ability of small-scale fisheries (SSF) in the developing world to better cope with and adapt to both external drivers and internal sources of uncertainty. This paper presents a framework for diagnosis and adaptive management and discusses ways of implementing the first two phases of learning: diagnosis and mobilising an appropriate management constituency. The discussion addresses key issues and suggests suitable approaches and tools as well as numerous sources of further information. Diagnosis of a SSF defines the system to be managed, outlines the scope of the management problem in terms of threats and opportunities, and aims to construct realistic and desired future projections for the fishery....

Optimal management of the New Zealand longfin eel (Anguilla dieffenbachii)
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Doole,   Graeme J.
Annual recruitment of the NewZealand longfin eel (Anguilla dieffenbachii) hasdecreased by 75 per cent since significant levels of commercial fishing began in the early 1970s. This motivates application of a multiple-cohort bioeconomic model to a New Zealand longfin eel fishery to investigate its optimal management and ascertain the suitability of existing regulatory policy. The use of historical harvest to calculate total allowable catch is asserted to be unsustainable based on recovery dynamics. In addition, individual transferable quota systems are argued to be fundamentally flawed for the protection of longfin fisheries because of high-grading, low-surplus production and a current lack of effective stock-assessment procedures. Area closure and the...

Status and management of the sea cucumber fishery of La Grande Terre, New Caledonia.
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Purcell,   Steven W.; Gossuin,   Hugues; Agudo,   Natacha N.
From October 2006 to May 2008, The WorldFish Center coordinated a ZoNéCo project to provide support to the Southern and Northern Provinces for decisions about how best to manage the sea cucumber fishery around La Grande Terre. We collected data during underwater population surveys, questionnaire-based interviews with fishers and processors, and landing catch surveys. A core aim was to furnish the Provinces with ‘ballpark’ estimates of the abundance and density of commercially important sea cucumbers on 50 lagoon and barrier reefs. Analysis and synthesis of the ecological and sociological data provide the basis for informed recommendations for fisheries management. Counts of trochus and giant clams on the reefs allow us to also describe the general status...

Approaches and frameworks for management and research in small-scale fisheries in the developing world
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Andrew,   Neil; Evans,   Louisa.
Commonly adopted approaches to managing small-scale fisheries (SSFs) in developing countries do not ensure sustainability. Progress is impeded by a gap between innovative SSF research and slower-moving SSF management. The paper aims to bridge the gap by showing that the three primary bases of SSF management--ecosystem, stakeholders’ rights and resilience--are mutually consistent and complementary. It nominates the ecosystem approach as an appropriate starting point because it is established in national and international law and policy. Within this approach, the emerging resilience perspective and associated concepts of adaptive management and institutional learning can move management beyond traditional control and resource-use optimization, which largely...

Ethnoecology and socioeconomic around an artificial reef: the case of artisanal fisheries from southeastern Brazil
Provedor de dados: Biota Neotropica
Autores: Lima,Juliano Silva; Zappes,Camilah Antunes; Di Beneditto,Ana Paula Madeira; Zalmon,Ilana Rosental.
Abstract: The objective of this study is to describe the ethnoecological aspects, valorization, and commercialization of target species caught by artisanal fishers on the northern coast of Rio de Janeiro, southeastern Brazil. The data were obtained through semi-structured interviews conducted with 60 fishers from the fishing community of Guaxindiba (21°29'S, 41°00'W), which is associated with the Z-1 fishers' colony. Eighty-nine species were cited by the fishers and 44.1% are important commercial fish in the region. The fishers cited five distinct zones used to fish: border zone (68 species), estuary (41 spp.), artificial reef (27 spp.), "malacacheta" (24 spp.), and open ocean (10 spp.). The fishery resources were classified according to their gastronomic...

SIZE AT SEXUAL MATURITY IN THE QUEEN CONCH STROMBUS GIGAS FROM COLOMBIA
Provedor de dados: Boletín de Investigaciones Marinas y Costeras (INVEMAR)
Autores: Avila-Poveda,Omar Hernando; Baqueiro-Cárdenas,Erick Raúl.
Size at sexual maturity was investigated in 346 queen conch, Strombus gigas, collected from the Archipelago of San Andres, Providencia and Santa Catalina (SAI), Colombia. Size at sexual maturity is defined as the size (based on total shell length and lip thickness) at which 50% of the population of queen conch sampled had mature and emission gonad developmental stages, based on microscopic examination (samples of gonads were processed by standardized histological methods). Only 12.14% of whole samples had mature and emission gonad developmental stages. The size at sexual maturity based on total shell length (STmat) was estimated to be STmat=249 mm for females (n=14), STmat=234 mm for males (n=28) and STmat=241 mm for both sexes (n=42). Lip thickness...
