Bilan et perspectives de developpement des DCP au Cap-Vert
Provedor de dados: 5
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...

Do FADs influence the geographical distribution of dolphinfish (Coryphaena hippurus)?
Provedor de dados: 5
Autores: Taquet, Marc; Reynal, Lionel; Laurans, Martial.
For most fisheries, increasing the local production of pelagic fish is the main objective of Fish Aggregating Devices (fads). This does not rule out the existence of a larger-scale impact, especially on the migratory behaviour of fish. The analysis of data collected during 25 experimental fishing surveys around Martinique between 1995 and 1997 has led to the hypothesis that fads influence the migratory behaviour of young dolphinfish. Unlike recent studies of dolphinfish migration in the Caribbean, which tend to show an annual migration pattern with a seasonal passage through the French West Indies, the experimental fishing surveys done over more than a year on a monthly basis on a single cohort, show that the migratory pattern of part of the regional stock...

An overview of the FADs fishery in the Mediterranean Sea
Provedor de dados: 5
Autores: Morales-nin, B; Cannizzaro, L; Massuti, E; Potoschi, A; Andaloro, F.
The Mediterranean small-scale fleet is highly adaptive, showing a dynamic fishing intensity and strategy, and exploiting seasonal abundant resources. In this area, the aggregatory behaviour under floats of juvenile fish has been used since ancient times to exploit oceanic migratory species such as dolphinfish (Coryphaena hippurus), using Fish Aggregating anchored Devices (fads). A total of 2 300 boats are engaged in this fishery from August to December, the main fishing areas being those around Malta, Tunisia, Sicily and Majorca. The fads ( arrow right m2) are made of different cheap floating materials, and are moored in fixed places, ranging from shore waters to areas 60 miles off the coast (1 500 m depth). Each boat deploys an average of 20 to 100 fads....

Contribution des DCP fixes et derivants a l'accroissement de la puissance de peche des navires de peche thoniere
Provedor de dados: 5
Autores: Le Gall, Jy.
Tuna world fisheries yield 3 million tons per year; the increase rate of whole production is constant and sustained since 30 years. This original figure for marine fisheries is due to enlargement of tuna fleets and fishing grounds over all the world ocean, the continuous increase of tuna fishing power by in board equipment and remote sensing equipment for searching and scouting (on board, aircraft, satellite, telecommunication_). During the last 20 years, the log-associated tuna fishing has contributed to the local individual and tuna fleets efficiency and fishing power either for large industrial tuna seiners by radio-equipped buoys on natural (debris) or artificial man-made logs. The same trend is noted for numerous artisanal tuna and large pelagic...

La promotion des DCP a Sao Tome et Principe: une experience pedagogique pour l'adoption durable d'une innovation
Provedor de dados: 5
Autores: Verdilhac De, P; Maggiorani, Jm; Debouvry, P.
A development programme for the promotion of FADs in Sao Tome and Principe has implemented an original interactive approach by granting a predominant place to the initiative of the target group and its participation in decision making. The appropriation process of the innovative fads by the beneficiaries takes place in three stages described herewith. the technical research phase. This consists of formally describing an idea in reply to an expressed or potential need. The envisaged fad type is developed and tested by the project's agents in order to obtain a technically appropriate prototype.- the research and adjustment phase. The fad is given to a small number of people to be used in real-life conditions. Reaction surveys will enable its pertinence to be...

Perspectives de developpement des DCP ancres dans les Petites Antilles. L'exemple de trois iles: Guadeloupe, Martinique et Curacao
Provedor de dados: 5
Autores: Reynal, Lionel; Van Buurt, G; Taquet, Marc.
This summary tackles the development of fisheries in the Caribbean using fads. It highlights the principal causes which explain why, in spite of more than thirty years of experimenting, fishing on fads has not developed as much as had been hoped. Whereas the deep-sea production of pelagic fish by the continental countries of the region has considerably increased since the early eighties, that of the Lesser Antilles has grown more slowly. Anchored fads have given the boats of the small-scale fisheries from three islands (Guadeloupe, Martinique and Curacao) access to these pelagic resources. The various modes of development and management of the fads observed in each island are described. The first available data are used to provide some indications of the...

Guam Fish Aggregating Device programme
Provedor de dados: 5
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...

Peche artisanale sur DCP et peche palangriere a la Reunion: antagonisme ou complementarite?
Provedor de dados: 5
Autores: Tessier, E; Poisson, Francois.
More than ten years after its launching, an evaluation of the results of the FADs programme carried on in Reunion Island has been made. Its implementation and its impact on artisanal fishery in Reunion Island have been analysed. This analysis demonstrates that, following a continuously ascending phase, the production of fish caught on fads has reached a plateau. Parallel to the FAD-associated fishery, the longline fishery has developed since 1991. This type of fishery includes production units whose operating zone is bordering the FAD installation area. Analysing the evolution of the small longliner sector is based on general activity indicators (number of ships, production, fish selling prices). Besides, a synthesis of the interactions between those two...

This paper constitutes a practical hand-book prepared for the international stage of fishing technology (Nantes, 1978, May 31 to June 30). The authors give many data on the fishing technology, on the fishing gear classification, the behaviour of fish in relation with the fishing gear, the environomental effects on fishing gear and methods and on fish behaviour effects on the fishing methods. They explain the conception and the construction of the principal models of fishing gear, the conception and the equipment of fishing boats. They also give explications on the detection and the attraction of fish. They expound the organisation and the planification of a fishing technology service.
