Etudes sur les mortalites larvaires de la coquille st Jacques Pecten maximus en ecloserie
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Robert, Rene; Miner, Philippe; Nicolas, Jean-louis; Mazuret, Michel; Connan, Jean-paul.
Larval mortalities occurring in molluscan hatcheries have often been associated with bacterial contamination. Although batches of oyster and clam larvae have been routinely reared in the hatchery of Argenton without antibiotics, high larval mortalities have been recorded with Pecten maxirnus under similar conditions. For this species, an addition of chloramphenicol was found necessary. However, this chemical has now been banned in Europe. Thus either substitition products or an improvement in the rearing procedures is essential. Studies carried out have shown that neither a decrease in larval density (1 larvae. ml"l) nor sea water change frequency (1 per day) had any positive effects. Furthermore, elective substances such as sugars were not suitable and...

La production aquacole de coquille Saint-Jacques (Pecten maximus) et le soutien scientifique à l'operation pilote

Aquaculture production of scallop has been identified by a series of technical operations during the past ten years programme under a partnership involving the fishermen organizations with regional and national grants. 3 million juveniles have been produced annually, giving a potential recapture by fishing of 100 to 120 tonnes 3 years later. Results in terms of technical and economical approach have pointed out the principal unknown factors responsable for high costs. 7he pilot programme aims to increase the production to reach a level of 5 million juveniles to support the fishery of the rade de Brest and induce new management of the resources. Two priorities were selected, control of the reproduction in the hatchery to obtain reliable larval and...

Observations on larval development and settlement of Patinofecten yessoensis in hatcheries
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Robert, Rene; Miner, Philippe; Mazuret, Michel; Connan, Jean-paul.
The influence of density on Patinopecten yessoensis larval development was studied during production of an F2 generation. Setting behaviour of P. yessoensis on PVC removable spat collectors, previously tested with Pecten maximus, was determined. Poor larval growth of P. yessoensis was observed at a larval density of 7 ·ml·1 and post larval settlement occurred mainly on the bottom of the baskets, as has been observed with the king scallop, P. maximus. The PVC collector is not suitable for either species of scallop.

Effect of Rhodomonas salina addition to a standard hatchery diet during the early ontogeny of the scallop Pecten maximus
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Tremblay, Rejean; Cartier, Simon; Miner, Philippe; Pernet, Fabrice; Quere, Claudie; Moal, Jeanne; Muzellec, Marie-louise; Mazuret, Michel; Samain, Jean-francois.
The main objective of this study was to identify algal diets that maximize the survival and growth and alter the biochemical content of Pecten maximus larvae with the aim of improving metamorphosis. We also evaluated the potential of the cryptophyceae Rhodomonas salina as a food source for these larvae. Two flagellates, Isochrysis aff. galbana (T) and Pavlova lutheri (P), and two diatoms, Chaetoceros gracilis (C) or Skeletonema costatum (S), were tested as two ternary diets, namely PTC and PTS. PTC and PTS were compared with diets that also included R. salina (R). The addition of R. salina and the replacement of C. gracilis by S. costatum in the traditional hatchery diet seem to be two interesting alternatives for increasing the productivity of larval...
