A fleet-metier based approach of the small scale fishing activity in the French West Indies ArchiMer
Guyader, Olivier; Reynal, Lionel; Demaneche, Sebastien; Berthou, Patrick; Daures, Fabienne.
The development of the ecosystemic approach for fisheries supposes to improve integrated analysis of fisheries by considering the biological as well as the socio-economic dimensions of the exploitation. A prerequisite for integrated analysis is the improvement in the knowledge of fleets structure, fleet evolution and allocation of fishing effort in the different fisheries. However, small scale fisheries are often characterized by a lack of knowledge on the vessel fishing activity. This paper first presents a data collection methodology recently applied in the French West (Guadeloupe and Martinique) for the follow up of the whole vessel population. Based on a statistical analysis of these data sets, the paper develops a fleet-metier matrix giving the...

A model for the phenotypic plasticity of North sea herring growth in relation to trophic conditions ArchiMer
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 evaluation of the policy of fishery resources management by TACs in European Community waters from 1983 to 1992 ArchiMer
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...

Le Balanced Harvest est-il une bonne idée ? Une approche par modélisation écosystémique pour reconstruire les pêcheries et la structure trophique en mer Celtique. ArchiMer
Perez, Ilan.
Balanced harvest has been suggested as a new paradigm of fisheries management in order to minimize the impacts of fisheries on marine ecosystems, by distributing the fishing pressure on all species and trophic levels, proportionally to the productivity of each group, to maintain their relative abundance in the ecosystem. However, this exploitation pattern has been criticized by a few scientists arguing that exploitation of all trophic levels may lead to a large ecosystem impact, due to the cumulative effects of fishing along the food web. There is no consensus within the literature about Balanced Harvest implementation and effects because scarce knowledge. Using Ecopath with Ecosim model of the Celtic Sea as case studies, we assessed the impacts of...

Le Dispositif de Concentration de Poissons (DCP): une alternative à la forte pression de pêche sur les ressources récifales de la Martinique ArchiMer
Taquet, Marc.
This paper describes the fishing activity in Martinique, French West Indies. It draws up the balance sheet of acquirements about marine resources of the island. The difficulties of fisheries management are discussed with reference to biologists and economists works in the last ten years. We also show how management efforts to decrease fishing pressure on reef resources has induced the implantation of a new technology: the Fish Aggregating Deviee. The differing histories of development of FADs in the French West Indies are compared. The positive results from the introduction of the FADs and the estimated risks due to the transferance of fishing pressure on the continental shelf is presented. The use of FADs to enhance the exploitation of marine resources is...

Perceptions et attentes des professionnels de manche est vis a vis de l'ecosysteme qu'ils exploitent ArchiMer
Prigent, Magali; Fontenelle, Guy.
The development of an ecosystemic approach to fisheries management requires the clear formulation of management objectives that make it possible to develop criteria to evaluate indicators. For an ecosystem, targets and limits are a matter of societal choice. Work to formulate these objectives is necessary. Within this perspective, this report presents a survey of the perceptions of Eastern English Channel fishing professionals on the state of the "marine ecosystem" resource. 29 people were polled during the month of June 2006 about their perceptions of the ecosystem as it was at a baseline time in the past, as it is today, and as it should be in future. Diagrams made it possible to formalise these perceptions. The people who were polled noticed a...

Programme pilote de gestion halieutique : groupe de propositions sur l'organisation de la gestion des pêches dans le golfe du Lion ArchiMer
Bertrand, Jacques; Catanzano, Joseph; Caboche, C; Rey, Hélène; Tempier, E.
Le début de la décennie 1990 a été marqué par la volonté des responsables nationaux et communautaires de faire évoluer les modalités de la gestion des pêches en Méditerranée. L'objectif du présent projet était de contribuer à cette dynamique par une analyse sur le fonctionnement de la pêche à partir de l'exploitation elle-même, à l'échelle de la zone du golfe du Lion. Le projet visait également à proposer, toujours à l'échelle de la zone étudiée, des voies d'évolution en vue d'un renforcement de la participation des professionnels à la gestion des pêches régionales dans le contexte communautaire. Le programme a été réalisé dans le cadre d'une collaboration entre une organisation professionnelle (le Comité national des pêches maritimes et des élevages...
