Captage de naissain de pectinidés en rade de Brest. Incidences sur les programmes d'aménagement. ArchiMer
Dao, Jean-claude; Caisey, Xavier.
Since 1973, spat collection bas been conducted by IFREMER in the bay of Brest. This collection aimed at providing juveniles of Pecten maximus (1973-77) and then Chlamys varia(1977-87) in order to improve the management of the fishing grounds of the two species. Since 1982, the efforts have been focussed on the P. maximus spat production through the hatchery/nursery systems and the intermediate culture. Juveniles are seeded above a minimum size to create an additional population. In parallel, the levels of spat yied/collector have been followed as a pre-recruit index. At present time, there is no increase of spat collection during 1985-1990. Moreover, the results rise up the question of water quality in the bay of Brest for this group apparently very...

La sensibilité des larves de pectinidés aux conditions d’élevage : le flux ouvert comme alternative aux mortalités massives ArchiMer
Holbach, Marine.
In many countries, aquaculture of pectinids depends on the success of artificial spat production in hatchery. This production is always unpredictable due to the variability of hatching rate and larval survival. Flow-through larval rearing systems were developed in Norway for the King scallop Pecten maximus and showed promising results. Unfortunately the system needs to be optimized since the larval yields and the densities used are still relatively low. In France, a small-scale (5 L) and high-density (≤ 300 larva mL-1) flow-through larval rearing system was successfully developed for oysters. First trials in such system and in similar conditions with P. maximus failed as we registered slower growth and high mortality rate in only a few days. It is known...

L'élevage hivernal du pétoncle noir Chlamys varia sur les côtes de Charente-Maritime. Résultats préliminaires en claire et en mer ouverte ArchiMer
Bodoy, Alain; Garnier, Jacqueline; Heurtebise, Serge.
Dans le cadre d'un programme de recherche financé partiellement par la région Poitou-Charentes, un élevage expérimental du pétoncle noir, Chlamys varia, a été réalisés dans deux sites aquacoles. L'un concerne la mer ouverte, au moyen de filière d'élevage de type subflottant, l'autre les bassins en terre du marais maritime (claire). Une production en écloserie et un prégrossissement intensif ayant été réalisé, le naissain d'une taille d'environ 18 mm a fait l'objet d'un élevage hivernal, selon un plan expérimental qui comprenait un facteur relatif au milieu d'élevage et un facteur relatif à la densité. D'importantes mortalités ont été constatées juste après la mise en élevage. Elles semblent être en relation avec le transfert des individus entre le site de...
