Résumé : A variety of researchers have carried out job satisfaction studies in fisheries during the last decades. Results have shown the significant role of self-actualization in the determination of job satisfaction which backs the reasoning that fishing is more than just a livelihood. This paper is based in a job satisfaction study carried out in three lobster fisheries in the Caribbean. Lobster fishing (Panulirus argus) is an important economic activity throughout the Caribbean Basin, both as a source of income and employment for the local population as well as foreign exchange for national governments. These countries differ significantly in structure of the fishery as well as governance arrangements. In this paper we wish to address the relation between these structural differences and fishers’ job satisfaction across the three countries. Results indicate fishers’ job satisfaction is significantly higher in small-scale fisheries.
De nombreuses recherches ont été réalisées ces dernières années sur le contentement au travail. Les résultats ont montré que l’activité de pêche n’est pas simplement un moyen de gagner de l’argent mais qu’elle résulte bien plus d’un choix délibéré. L’article expose les résultats d’enquêtes menées auprès de pêcheurs de langouste en République dominicaine, au Nicaragua et en Jamaïque. Globalement la satisfaction que les pêcheurs ont de leur travail est bien plus importante pour les pêcheries artisanales que pour les pêcheries plus fortement dotées en capital.

Résumé : The development on the ecosystem-based approach to fisheries implies to improve integrated analysis of fisheries by considering the biological as well as the socio-economic dimensions of the exploitation and thus, an improvement in the knowledge of fleets structure, evolution and activity. Since 2000, Ifremer has been implemented a Fisheries Information System (FIS), a multidisciplinary monitoring network allowing an integrated and comprehensive view of fishery systems including biological, technical, environmental and economical components. The FIS covers all the French fisheries, including the so-often neglected small-scale fisheries. One of the originalities of the FIS lies in the fleet monitoring procedure: a comprehensive collection of annual activity calendars aiming at characterizing the inactivity or activity of the vessels each month of the year and, in the latter case, the métiers practised (use of a gear to target one or several species) and the main fishing areas. This survey covers all the French fishing fleets and provides minimum but exhaustive information on the vessels. It is particularly instructive for the small-scale fisheries, where catches and effort data are often incomplete. Furthermore, this exhaustive data allows stratifying the fleet in fleets (typologies) and thus provides the basis (i) for the implementation of sampling schemes to estimate catches, landings, discards or economic performance of the different fleets and (ii) for the development of a fleet-métier matrix giving the possibility of identifying at the time, the structure of the whole fleet in fleets, the métier polyvalence of the vessels and the allocation of fishing effort on the different exploited fishing resources.

Résumé : The availability in interesting sites and the zootechnical performances of tropical fish are two impo rt ant assets in favor of the development of fish farming in the Caribbean islands. This repor presents a technical and financial analysis of red drum farming projects in floating cages in Martinique(French West Indies). This project analysis makes it possible to compare the economic feasability of a small-scale production system with that of a semi-industrial one submitted to different technical constraints. The main criteria of the project analysis are the profitability of the funded capital, the financial feasability during the buildup period, the profitability at a steady state and the cost price. Production costs are hi gher in the the small-scale enterprises than in the semi-industrial ones, thanks to better capita] productivity and better labour productivity. An analysis of sensitivity to the variations ofbiological and economical parameters is also contained in the report. The results of these studies indicate that Caribbean fish farming could be profitable, due to the rapid buildup of the facilities and to the short production cycles. Nevertheless, attention should be paid to the risk of storms and hurricanes in this part of the world. Moreover, the analysis of sensitivity highlights the great influence of seed price.

Les bonnes performances zootechniques des poissons tropicaux et la disponibilité en sites propices sont deux atouts majeurs favorables au développement de l'aquaculture de poissons dans les îles des Caraïbes. Ce rapport présente l'adaptation d'un outil de simulation technico- économique à l'éleva ge de l'ombrine en cages flottantes dans le contexte martiniquais. Cet outil permet de disposer d'éléments de comparaison sur la faisabilité de deux systèmes de production, Fun de type artisanal et l'autre de type semi- industriel, soumis à des contraintes techniquesdifférentes : rentabilité du capital investi, faisabilité financière au démarrage, rentabilité en année de routine, prix de revient. Une analyse de sensibilité des résultats aux variations de paramètres biologiques et économiques est également présentée. L'analyse de ces projets fait apparaître une rentabilité satisfaisante de l'activité, liée à la rapidité de mise en route des installations et à la brièveté des cycles de production. Line grande attention doit être cependant portée sur les risques d'accidents climatiques fréquents dans cette région du globe (cyclone, mais aussi tempête...). L'analyse de sensibilité montre la grande influence du prix d'achat de l'alevin, en particulier sur les résultats de la variante artisanale, dont le coût de production de l'ombrine rendue à quai, est plus élevé que celui de la variante semi- industrielle.

Résumé : 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 institutional framework may be a handicap at the level of the management (of the programme itself, and/or of some possible conflicts of uses); - to carry out an assessment of the former experiments. It emphasized the insufficiency of the follow-up and the maintenance of the structures, of which the lifespan varied at the most between four and six months, as well as the positive effects of the concentration, and the interest of the fishermen already sensitized with these structures.

Résumé : The stock of Lambi, Strombus gigas (gastropod: strombidae), coastal benthic resource, has been exploited artisanally since the prehistoric period in Martinique. Nowadays, three lines of work exploit the species: free diving, nets (since the middle of the century) and scuba diving since 1985. This report presents the activity of each line of work, surveyed directly from 1986 to 1987: fishing zones and resource allocation, production, effort and performance, detail of catches (by length). The socio economic characteristics of the lambi fishermen are studied. The significant production of leisure fishing is also estimated. The decrease in the production and performance, as well as the lowering of the size of the first catch for about thirty years show that the stock is overexploited. The biological phenomenon of the stock: growth of the shell (length and shell lip), growth in weight, acquiring of sexual maturity, natural mortality are studied. The factors of mortality through fishing are estimated by class of length for the current exploitation regime by pseudo-cohort analysis. If the results confirm that the stock is overexploited, the level of overexploitation of the stock cannot be specified because of the presence of a number of lipped adults not yet too exploited in water deeper than 20 metres. The analysis of the dynamic process of the exploited population indicates two ways to the production of the stock: the forcing of the recruitment and the regulation of the exploitation regime. The lack of economic profitability of the production of juveniles over 30 mm and the difficulties raised by their collection in their natural habitat lead to the rationalization of the exploitation. The production and performance (by recruits) simulations performed for different exploitation regimens indicate that the only two conceivable options are the introduction of a minimum catch size, i.e. lambi with forming lip, and the regulation of the fishing effort. The socio-economic implications of the introduction of the determined management measures show that their applicability level is very low, because of the Martinique fishermen polyactivity, their low socio-economic level and mostly because of the free access to the resource. As a consequence, it is suggested to create new professional structures with a wide jurisdiction, in order to locally manage the marine areas, their use and their resources. (unverified OCR)
Le stock de lambi, Strombus gigas (gastéropode: strombidae), ressource benthique côtière, est exploitée artisanalement depuis l'époque préhistorique en Martinique. Trois métiers exploitent actuellement l'espèce: plongée libre, filets (depuis le milieu du siècle) et plongée en scaphandre autonome depuis 1985. Ce rapport présente l'activité de chaque métier, suivie de 1986 à 1987 par une enquête directe: zones de pêche et allocation de la ressource, productions, efforts et rendements, composition en longueur des captures. Les caractéristiques socioéconomiques des pêcheurs de lambi sont étudiées. La production d'une pêche plaisancière non négligeable est estimée. La diminution de la production, des rendements et l'abaissement de la taille de première capture depuis une trentaine d'années révèlent que le stock est surexploité. Les phénomènes biologiques du stock: croissance de la coquille (longueur et pavillon), croissance en poids, acquisition de la maturité sexuelle, mortalité naturelle sont étudiés. Les coefficients de mortalité par pêche sont estimés par classe de longueur pour le régime d'exploitation actuel par l'analyse de pseudo-cohorte. Si les résultats confirment l'état surexploité du stock, le niveau de surexploitation ne peut être précisé en raison de l'existence d'adultes pavillonnés encore peu exploités sur les fonds de plus de 20 mètres. L'analyse des processus dynamiques de la population exploitée indique deux voies pour restaurer la production du stock: le forçage du recrutement et la régulation du régime d'exploitation. Le manque de rentabilité économique de l'élevage des juvéniles au-delà de 30 mm et les difficultés pour leur collecte dans le milieu naturel conduisent à rechercher la rationalisation de l'exploitation. Les simulations de la production et du rendement par recrue réalisées pour différents régimes d'exploitation indiquent que seule la mise en place d'une taille minimale de capture, i.e le lambi au pavillon en formation, et une régulation de l'effort de pêche sont envisageables. Les implications socio-économiques de la mise en oeuvre des mesures de gestion déterminées montrent que leur niveau d'applicabilité est très faible, en raison de la polyactivité des pêcheurs martiniquais, de leur faible niveau socioéconomique et surtout, du régime de libre accès à la ressource. Aussi, il est proposé la création de nouvelles structures professionnelles aux compétences larges, qui permettraient, pour chacun des bourgs, une gestion locale de l'espace marin, des usages et des ressources.

Résumé : Payao is a traditional concept, which has been successfully commercialized to increase the landings of several species valuable to the country's export and local industries. It has become one of the most important developments in pelagic fishing that significantly contributed to increased tuna production and expansion of purse seine and other fishing gears. The introduction of the payao in tuna fishing in 1975 triggered the rapid development of the tuna and small pelagic fishery. With limited management schemes and strategies, however, unstable tuna and tuna-like species production was experienced in the 1980s and 1990s. In this paper, the evolution and development of the payao with emphasis on the technological aspect are reviewed. The present practices and techniques of payao in various parts of the country, including its structure, ownership, distribution, and fishing operations are discussed. Monitoring results of purse seine/ringnet operations including handline using payao in Celebes Sea and Western Luzon are presented to compare fishing styles and techniques, payao designs and species caught. The fishing gears in various regions of the country for harvesting payao are enumerated and discussed. The inshore and offshore payaos in terms of sea depth, location, designs, fishing methods and catch composition are also compared. Fishing companies and fisherfolk associations involved in payao operation are presented to determine extent of utilization and involvement in the municipal and commercial sectors of the fishing industry. The issues and problems concerning the use of payao, and its biological, economic impact as well as management aspect are presented. Recommendations are given for future research and actions.

Résumé : The first part describes the evolution of the world sea fisheries from 1950 to 1977 and their present state : a decline of the growing rate of the catches, their biological structure and their distribution in the oceans according to the depth, the distance from the continent and the latitude. Then the biogeographical fishery complexes are defined, being characterized by assemblages of commercially valuable and actually caught species. These complexes are arranged according to the latitude with sometimes longitudinal subdivisions. At last with technical and economical criteria, such as the yield of the fisheries, the finality of the catches and the conditions of the exploitation which add themselves to the biogeographical complexes, the authors attempt to single out geographical fishing provinces.
La première partie analyse l'évolution de la pêche mondiale de 1950 à 1977 et sa situation présente : ralentissement du rythme de la croissance des captures, composition faunistique et répartition des pêches dans l'océan selon la profondeur, la distance à la côte et la latitude. Ensuite sont définis les complexes biogéographiques de pêche, caractérisés par des assemblages d'espèces commercialement intéressantes et effectivement utilisées. Ces complexes s'ordonnent selon la latitude avec parfois des subdivisions méridiennes. Enfin, à l'aide de critères techniques et économiques, tels que le rendement des pêches, la finalité des captures et les modalités de l'exploitation qui viennent se superposer aux complexes biogéographiques, les auteurs tentent d'individualiser des provinces géographiques de pêche.

Résumé : In order to provide reliable scientific advice and support for fisheries management, it is necessary to evaluate the biological and economic sustainability of complex fisheries, such as multi-species multi-fleet fisheries. Existing policy-screening modelling tools are not fully suitable in this purpose due to either an over-simplified description of population dynamics, or due to the lack of consideration of economic aspects. In this paper, we present a package that enables quantitative bioeconomic assessment of management scenarios. Population dynamics is described through spatially- and seasonally-explicit models. Exploitation dynamics is characterized by several fishing activities with specific spatial and seasonal features, and practiced by several kinds of vessels with specific technical characteristics. Exploitation costs and revenues are considered at several levels: the fishing trip, the fishing unit (vessel and crew), and the vessel owner. The model is generic and can be used for different types of fisheries. A database is attached to the software for the storage and updating of information for each fishery. This includes the specification of model dimensions and of the parameters describing populations and exploitation. Several model assumptions regarding either population or exploitation may be adapted to suit a specific fishery. Both policies and corresponding fishers' response may be interactively specified through JAVA (TM) scripts. This version of ISIS-Fish allows for the calculation of biological and economic consequences of a range of policies, including conventional ones like catch and effort controls, and alternative policies such as marine protected areas. To facilitate policy-screening in a high-dimension parameter space, the software includes features, like interfaces for sensitivity analysis and simulation queues. (C) 2009 Elsevier B.V.

Résumé : Selective fishing pressure on more highly valued marine living resources is one of the key factors proposed to explain changes occurring in fish communities and associated landings of commercial fisheries. The aim of this paper is to establish the nature of changes in the landings of French fishing fleets operating in the Bay of Biscay in the period 1973-2002, and whether these changes could be related to the relative economic attractiveness of different fish species. The analysis focuses on trends observed in the landings of all commercial fish species over the last three decades. It is based on data of annual quantities landed and ex-vessel prices compiled from official French landings records, and on bio-geographical descriptors of these species derived from published data. Using simple index numbers and multivariate analysis, we examined changes in total landings in terms of their volume and value, as well as changes in their composition. We show that the composition of landings significantly changed over the study period, with an increase in the proportion of pelagic species, of lower economic value. The average ex-vessel price of production by the fleets tended to decrease from the late 1980s; partly due to a cross-species drop in prices, occurring mainly after 1993, but also to the increased proportion of low-priced species in the landings. This caused a significant drop in the total gross value of production in the second half of the study period.
La pression de pêche sélective sur les ressources marines vivantes de forte valeur est un des facteurs-clés proposés pour expliquer les changements qui surviennent dans la structure des communautés de poisson et dans les débarquements des pêcheries commerciales associés. L'objectif de cet article est d'établir la nature des changements dans les débarquements des flottilles de pêche françaises opérant dans le golfe de Gascogne, et d'examiner les relations entre ces changements et l'attractivité relative des espèces de poisson d'un point de vue économique. L'analyse se concentre sur les tendances observées au cours des trois dernières décennies dans les débarquements de toutes les espèces commerciales de poissons effectués par les flottilles de pêche opérant dans le golfe. Elle s'appuie sur des données concernant les quantités annuelles débarquées, les prix compilés à partir des enregistrements officiels des débarquements français, et les données publiées concernant les caractéristiques biogéographiques des espèces étudiées. En s'appuyant sur des indices simples et une analyse multivariée, on examine les changements des débarquements totaux en volume et en valeur, ainsi que les changements dans leur composition. On montre que la composition des débarquements a fortement changé au cours de la période étudiée, avec un accroissement important de la part des espèces pélagiques, de plus faible valeur. Le prix moyen de la production a eu tendance à décroître depuis la fin des années 1980. Ceci est en partie dû à une chute des prix de l'ensemble des espèces, après 1993, et en partie lié à l'accroissement de la part des espèces de plus faible valeur dans les débarquements. Une baisse importante de la valeur de la production en a découlé sur cette deuxième moitié de la période d'étude.

Résumé : Les ressources marines constituent une richesse économique d’une grande importance pour un grand nombre de pays de la planète. Du fait de l’action de l’homme, ces ressources subissent une fragilisation et une raréfaction dues entre autres à la pollution, à la surpêche, à l’urbanisation intensive... S’ajoute à cette liste, depuis quelques années, le réchauffement de la planète qui affecte d’une manière sensible la diversité biologique marine. Pourtant les réponses internationales face à cette dégradation, au-delà du fait qu’elles sont timides, sont rares. Il faudra dès lors se rabattre sur les solutions de lutte globale contre le réchauffement de la planète entreprise par la communauté internationale afin de contrer cette dégradation.
Marine resources are a wealth of great economic importance for many countries in the world. Due to the action of man, these resources undergo embrittlement and rarification among others to pollution, overfishing, urbanization, intensive ... Added to this list in recent years, the global warming that affects a significantly marine biodiversity. Yet the international response to this degradation, beyond the fact that they are shy, is rare. It will therefore fall back on solutions to the global fight against global warming taken by the international community to counter this degradation.

Résumé : While the majority of small-scale coastal fisheries are found in developing nations, a considerable number exist in developed nations as well. Indeed, small-scale fisheries are strongly represented in all European Union (EU) Member States, 81% and 87% of the EU 25 whole fleet is composed of vessels less than 12 and 15 meters long respectively. In 2000, European regulation established a fisheries data collection framework including economic information requirements in order to provide the scientific basis for the implementation of the Common Fisheries Policy. This paper presents the methodology designed to collect the relevant economic data and characterize the status of the French fleets from an economic perspective. Based on stratified sampling plan including the following of small-scale fleets, data collection by field survey is based on a single questionnaire for all the fleets, whatever the size of the vessel, the gear used, the fishing area or the species targeted. It provides a large data set including earnings and costs but also capital, employment, fishing activity figures. Statistical analysis through a revenue model gives the basis for a re-assessing of the small-scale fisheries contribution to national production. Economic indicators such as gross added value, revenues, and direct employment are derived from the data set. The significant role of small scale fisheries in the French fishing sector is established and the impact of the rising fuel costs in fisheries is discussed.

Résumé : The foreign artisanal fishery of Pointe-Noire (Congo) significantly evolved since its beginning, in the 1950s, by the number of fishermen and canoes, as well as the fishing techniques used and by its socio-economic organization. The fishery for Sardinella by surface gill-nets, its main activity, is based on common ownership and savings, thus allowing partial reinvestment of fishing revenues, the riskier (such as bottom gill-net) being left to individual initiatives. The foreign fishery employs many Congolese fishermen, in a permanent or very occasional way. However no improvement effect seems to have taken place in favor of the local artisanal fishery.
La pêcherie artisanale étrangère de Pointe-Noire, dite « béninoise », a significativement évolué depuis ses débuts, dans les années 1950, tant par ses effectifs en hommes et en pirogues, que par les moyens techniques et socio-économiques mis en oeuvre. La pêche de la sardinelle au filet maillant de surface, qui en est l'activité principale, repose sur la propriété et l'épargne collectives, qui assurent le réinvestissement partiel des revenus, les pêches où les risques sont plus élevés (filet dormant de fond) ne sont pratiquées qu'à titre individuel. Outre son rôle essentiel d'approvisionnement en poisson de la région de Pointe-Noire et les emplois indirects qu'elle crée, la pêcherie béninoise emploie de nombreux pêcheurs congolais, de façon permanente ou très occasionnelle ; cependant, aucun effet d'entraînement ne semble s'être produit au profit de la pêche artisanale locale.

Résumé : Small-scale fisheries have traditionally received less research effort than large-scale fisheries and are generally under-studied in Europe. In spite of their comparatively low volume of catches and economic importance, small-scale fisheries are socially important and an integral part of the European coastal zone. Considering the high heterogeneity of situations and the paucity of quantitative data, we used an analytical methodology based on the comparative method. We carried out an analysis of small-scale fisheries (SSFs) in Europe based on a selection of nine case studies. Our objective was to obtain a comprehensive description of small-scale fleets covering different areas/fisheries/species, encompassing the diversity and specific conditions under which SSFs operate, in order to demonstrate the ecological and social sustainability of this often overlooked fisheries segment. A common approach formulated so that the case studies could be compared with the case histories of other competing users, required that for each set of criteria – technical, biological, socio-economic, and institutional – a set of relevant items and indicators was established. An analysis of characteristics common to the selected case studies is conducted and an attempt made to extend our comparisons to the whole of the European Union. Our results show that (as compared with large-scale fleets, their main competitor) small-scale fleets: (i) are composed of smaller vessels and, consequently, travel lower distances to fishing grounds, and are more reliant on coastal areas; (ii) have smaller crews (although the global employment figure is similar to that of large-scale fleets in Europe); (iii) use mostly, but not exclusively, passive gears; (iv) use multi-purpose fishing approaches, and can change the fish species they target during the year; (v) have lower extraction rates; (vi) have lower total capital investments (including fishing rights), turnover and costs; and (vii) have lower fuel consumption, making them less sensitive to changing oil prices. Dependence on subsidies is lower (viii). Involvement in fisheries management is variable, conservation and access regulation measures are largely local in origin. For the selected case studies, the most significant competitors are large-scale fleets, and recreational fisheries, but other sources of interaction (water quality, invasive species, etc.) cannot be ignored.

Résumé : Since 2000, Ifremer has been implemented a Fisheries Information System (FIS), in strong collaboration with the DPMA (Direction of fisheries and aquaculture of the French Ministry of Agriculture and Fisheries). The FIS aims at building an operational and multidisciplinary monitoring network for scientific purposes, allowing a comprehensive view of fishery systems including their biological, technical, environmental and economical components. The objectives of the FIS are (i) to provide the specifications and methodologies for the collection, storage and processing of fisheries data, with the constant concern to harmonise all these procedures on a national scale, (ii) to improve data management system and access to data for a wide-spread public, and (iii) to produce and distribute relevant datasets, indicators and synthesis, for understanding and evaluation, including bio-economic diagnostics of the fisheries, and assessment of the short and long-term impacts of fisheries management scenario and measures. The FIS covers all the French fisheries, including overseas territories and small-scale fisheries, for which data are often hardly available or missing, whereas two thirds of the French vessels are less than 12 meters long. The challenge was to establish a statistical and an integrated approach supporting bio-ecological and economic issues. To further an integrated analysis of the fishery systems, the wide range kinds of data - including acoustic surveys, biological in-situ observations, environmental observations, as well as fishing statistics (landings and efforts) or economic data - are managed in a single data management system, based on an integrated relational data base with geographical facilities.

Résumé : International audience
Anthropogenic impacts are increasingly affecting the world's oceans. Networks of marine protected areas (MPAs) provide an option for increasing the ecological and economic benefits often provided by single MPAs. It is vital to empirically assess the effects of MPA networks and to prioritize the monitoring data necessary to explain those effects. We summarize the types of MPA networks based on their intended management outcomes and illustrate a framework for evaluating whether a connectivity network is providing an outcome greater than the sum of individual MPA effects. We use an analysis of an MPA network in Hawai'i to compare networked MPAs to non-networked MPAs to demonstrate results consistent with a network effect. We assert that planning processes for MPA networks should identify their intended outcomes while also employing coupled field monitoring-simulation modeling approaches, a powerful way to prioritize the most relevant monitoring data for empirically assessing MPA network performance.

Résumé : When Henry B. Plant brought the railroad to Tampa in 1884, he opened the door for many businesses to locate and flourish here. The railroad was at the center of the city's economy. From downtown it went to Port Tampa where one could board a Plant steamship to Jamaica, Cuba, New Orleans, Bermuda or other destinations. A spur of the rail line brought the train up to the west front of the hotel so guests could depart the train and walk directly into the lobby. The Tampa Bay Hotel cost approximately 2.5 million dollars to build and $500,000 to furnish. Consisting of 511 rooms, some of which were suites of 3-7 rooms, it provided a degree of luxury never before seen in Tampa. Most of the rooms had their own baths and all had electricity and telephones. In addition, guests were surrounded by a varied collection of furniture, porcelains, Venetian-style mirrors, and sculptures gathered by Mr. and Mrs. Plant in their travels in Europe. The Tampa Bay Hotel opened in 1891 amid wide fanfare and celebration. Henry Plant's dream was now a reality. The newspapers of the day described it as "brightly illuminated, filled with sumptuous decorations, thrilling music and graced with turrets, domes and minarets towering heavenward and glistening in the sun." It was a Victorian palace. The hotel was a lively place with balls, tea parties, and organized hunts during the winter social season. It was open seasonally from December to April in the 1890's. Once a guest arrived at the hotel, he needed to be entertained. Guests went wild game hunting as well as fresh and salt-water fishing. Water sports were also included like sailing, rowing, and canoeing. For the less adventuresome, there were bicycles, carriages, and rickshaws to ride you around the property. The hotel also offered golf, tennis, shuffleboard, billiards, and even a racetrack.

Résumé : The full exploitation of the world fishery resources has drastically modified the prospects and conditions for progress in fisheries. It was detenninant in the change of the Ocean Regime. Moreover, it widened considerably the range of issues which have to be addressed for an efficient use of marine living resources. Assessment approaches for complex fisheries, carrying capacity of basins and management of bivalve mollusc stocks, natural variability of fish stocks and management implications, methods for access regulation, economic rent, resources and use rights allocation, nature of aitisanal fisheries, strategies for fishery development in Third World countries, international dimensions of fisheries, etc. are among the issues reviewed in this book by scientists of international repute.
La pleine exploitation des ressources halieutiques mondiales a profondément modifié les perspectives et les conditions de progrès de la pêche. Elle a pesé lourd dans l'acccptalion du nouveau régime des océans. Surtout, elle a considérablement élargi le champ des questions à aborder pour mieux valoriser les ressources vivantes de l'océan. Méthodes d'évaluation de pêcheries complexes, capacité biotique des bassins et aménagement des cheptels coquilliers, variabilité naturelle des stocks et conséquences pour l'aménagement des pêches, méthodes de régulation de l'accès, rente économique, allocation de ressources communes et de droits d'usage, spécificité des pêches artisanales, stratégies de développement de la pêche dans les pays du Tiers Monde, dimensions internationales de la pêche, etc. figurent parmi les thèmes qu'abordent dans cet ouvrage des spécialistes de notoriété mondiale.

Résumé : 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 system design. Several cost-cutting measures being considered include the use of reliable solar-powered navigation lights to reduce the number of maintenance trips required, and switching to a newer generation of lighter, more durable buoys and mooring systems. Average time on station for a dawr fad system is nearing two years. Interestingly, in most cases where an errant system is recovered, the failure in the mooring system was observed to occur at a depth from 35 to 500 metres. These observations have led to speculation that additional protection of the mooring line down to 500 m may result in doubling the average time on station of most FAD systems.

Résumé : Academia and management agencies show a growing interest for ecosystem-based fishery management (EBFM). However, the way to operationalize this approach remains challenging. The present paper illustrates how the concepts of stochastic co-viability, which accounts for dynamic complexities, uncertainties, risk and sustainability constraints, can be useful for the implementation of EBFM. In the present case, this concept is used to identify fishing strategies that satisfy both ecological conservation and economic sustainability in a multi-species, multi-fleet context. Economic Viability Analysis (EVA) and the broader Co-Viability Analysis (CVA), are proposed to expand the usual Population Viability Analysis (PVA) and precautionary approach. An illustration is proposed, using data on the fisheries of Bay of Biscay (France) exploiting the stocks of nephrops and hake. Stochastic simulations show how CVA can guarantee both ecological (stock) and economic (profit) sustainability. Using 2008 as a baseline, the model is used to identify fishing efforts that ensure such co-viability. (C) 2012 Elsevier B.V. All rights reserved.

Résumé : (not controled OCR) like most other caribbean islands, martinique suffers a reduction in fisheries resources and is now a net importer of seafood products since no major expansion of aquaculture production has been done. nevertheless, this island has numerous assets for marine aquaculture development : tropical clean waters, developed infrastructures and market channels, financial support for research, training and extension due to its tight political and economic connection with france. red drum is a subtropical fish introduced in martinique in 1985 from the south of usa for aquaculture purposes. from 1987 to 1993, ifremer worked on rearing techniques in martiniquan conditions. once the farming techniques were perfected, questions raised about red drum marketing potential and of economic viability of red drum farms in order to attract investments and entrepreneurs. that is the reason why a market analysis and a financial analysis have been carried out. the results of these studies indicate that martiniquan fish farming could be profitable, due to the rapid build-up of the facilities and to the sho rt production cycles. the good quality of infrastructures in martinique, the high purchase power of the population in comparison with most caribbean islands and the frequent air links with europe are important comparative advantages. the market analysis has revealed a good potential on the domestic market thanks to the development of the supermarkets, but has underlined the price constraint. for the french market too, production costs have to be lowered in order to compete on a market dominated by salmon.
