Grands pélagiques et Dispositifs de Concentration de Poissons (DCP) en Martinique (Antilles françaises) ArchiMer
Taquet, Marc.
Les ressources récifales et côtières du plateau insulaire de la Martinique subissent une pression anthropique croissante et ne sont plus en mesure d'assurer un revenu suffisant aux pêcheurs professionnels. La présente étude a pour objectif d'accompagner le redéploiement de l'activité de la flottille martiniquaise de proximité vers l'exploitation des ressources en grands poissons pélagiques à l'aide de dispositifs de concentration de poissons (DCP), sans imposer un changement d'échelle des unités d'exploitation. Les travaux sont développés selon deux axes complémentaires (i) l'amélioration technologique des DCP, (ii) une meilleure connaissance de la biologie des grands poissons pélagiques exploitables dans la zone d'activité de la flottille. La modélisation...

L'agrégation de thons de sub-surface au sein du système [DCP ancré - macronecton - environnement - pêche] en Martinique : étude hiérarchique par méthodes acoustiques, optiques et halieutiques ArchiMer
Doray, Mathieu.
Artificial Fish Aggregating Devices (FADs) are known to concentrate tropical tunas. This aggregative behaviour drastically increases the vulnerability of these species to fishing. Alternatively, FADs can be used as oceanic observatories to study the aggregative behaviour of large pelagic fish. We conducted sea surveys in Martinique (Lesser Antilles) to i) establish a typology of the pelagic fish aggregations found around moored FADs ii) study their relations with their biotic and abiotic environment and the local fishery. The mean biomass of large pelagic fish aggregations was also estimated to provide scientific inputs to achieve a sustainable management of the moored FAD fishery. The first part presents the background of the study. We introduce the...

Le comportement agrégatif des dorades coryphènes (Coryphaena hippurus) autour des objets flottants ArchiMer
Taquet, Marc.
The aggregative behaviour of the dolphinfish (Coryphaena hippurus) is studied in order to improve our knowledge of the mechanism involved in the association of this species with the floating objects and to evaluate its potential impact in term of exploitation, targeted or not. This PhD thesis is composed of four chapters. Through an extensive analyze of the literature, the first chapter takes stock of the present knowledge on the FADs, on the aggregative behaviour of pelagic fish and on the dolphinfish. The second chapter deals specifically with the aggregative behaviour of the dolphinfish by the way of acoustic tagging of fish carry out during offshore campaigns around drifting FADs. The feeding habits of the dolphinfish around FADs are the main purpose...

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...

Perspectives de développement de la pêche associée aux DCP ancrés dans la Caraïbe ArchiMer
Reynal, Lionel; Doray, Mathieu; Carpentier, Andre; Druault-aubin, Vomakassi; Taquet, Marc; Lagin, Alain.
Deployment of anchored FADs has opened large pelagic resources to smallscale fisheries, which usually operate nearshore. The main difficulties in using FADs for fishing have now been identified. It concerns principally the design of FADs, their location, and also the type of management and exploitation. During the initial phase of FAD development, particular problems are mentioned, namely voluntary deterioration of the devices, marketing of the catches ... FADs exploitation in the area can still he optimised. The impact of FADs densities and locations (depth, distance from shore) on the concentration offish resources or on fisheryproduction is not established. Environmental impact of FADs is not weIl evaluated either. We would like to implement a workshop...

Technologie des dispositifs de concentration de poissons et techniques de pêche aux gros pélagiques. Compte rendu d'essais effectués pendant l'été austral 1989-90 ArchiMer
Biais, Gerard; Taquet, Marc.
Fish aggreagating devices (FAD), "semi-heavy" models, have been anchored all around La Réunion Island since 1988. For maximising profits derived from them, "light" FAD less expensive have been designed and locally unused fishing gears were tried. The use of this latter appears to be limited in local context, but in contrast the use of "light" FADS seems an interesting way. Their design calculus are given. NOT CONTROLLED OCR
