Ressources démersales et descriptions des pêcheries des bancs de Saint-Martin et Saint-Barthélémy
Provedor de dados: 5
Autores: Lorance, Pascal.
Une évaluation de la variabilité du phénomène ciguatérique est réalisée et montre qu'aucune cartographie précise des zones ciguatériques n'est possible à cette échelle. Le rejet systématique des espèces à «risques» reste la méthode la plus sûre pour éviter des intoxications, mais il ne peut être exclus que quelques poissons appartenant à des espèces présumécs saines s'avèrent toxiques. Les rendements obtenus au cours de ces trois séries de campagnes de pêche sont présentés dans ce document ainsi que les résultats des tests comparatifs des secteurs et des saisons (sèche et humide). Une description des captures (composition spécifique, distribution des fréquences de taille des principales espèces) donne des indices qualitatifs d'une exploitation modérée sur...

Ressources démersales du talus insulaire de la Martinique
Provedor de dados: 5
Autores: Guillou, Alain.
A series of experimental fishing stations by means of bottom trarnmelnets have been conducted on the slopeof Martinique between 100 and 300 mn depth from november 1986 to march 1988, as part of a program entitled «Antillean Fisheries study» of the Pôle de Recherche Oceanologique et Halieutique Caraïbe». The species composition of the catches and the length frequencies of the potential commercial species, with a detailed analysis of their yields according to the depth and to the geographie localization are given. The whole average yield reaches 20 to 25 kg, two thirds of sharks, for 100 rn trarnmelnet set during approximately twenty hours. Furthennore, the main technical, commercial and human problems which are necessarily to be integrated and elucidated...

Autores: Kopp, Joel; Messiaen, Gregory; Le Gagneur, Eric; Cornette, Florence; Ropert, Michel.
Crassostrea gigas and Mytilus edulis are reared in four areas along the eastern coast of Cotentin (Normandy).  Every five years, a stock assessment survey, based on a stratified random sampling is carried out using aerial photographs. During September 2000, oysters bags and mussel banks random samplings have been weighed on leasing grounds and in random sampled farms in order to evaluate the overall total gross and net weights breeded (oysters 40 000 and mussels 17 000 metric tons, net weights). Age compositions of each stock in each rearing area have been computed.  This last stock assessment showed that cultural regulations are less and less observed in Normandy's breeding areas. A strong increase in bag densities has been noticed since 1995. As stock...
