in mollusc hatcheries. Consequently, we assessed themost commonly used species to establish their growth and size profiles, their cytomorphological, biochemical, biomolecular identification as well as their cytometer signs, and also their ability to grow under extreme conditions of temperature and salinity. This work aimed at matching the conformity of the strains used in Argenton (dispatched to most of the French commercial hatcheries) to those of a referenced culture collection. A previous screening preceded this study, because of the 45 species and/or clones held originally, Argenton kept no more than 15 species. As most of the latter are also represented in referenced collection, our strains are therefore correctly identified. On the other hand, the...

Competition for food in the larvae of two marine molluscs, Crepidula fornicata and Crassostrea gigas ArchiMer
Blanchard, Michel; Pechenik, J; Giudicelli, E; Connan, Jean-paul; Robert, Rene.
The degree to which larvae of the invasive American slipper limpet (Crepidula fornicata) and the Japanese oyster (Crassostrea gigas) may compete for food was examined during 2003 in the laboratory. Larval microalgae uptake, growth and mortality were compared for larvae fed each of six species of unicellular algae, ranging in length from 2 to 10 mu m. Tested diets included the two flagellates Tetraselmis chui (Prasinophyceae) and Isochrysis affinis galbana (T-ISO, Haptophyceae), one member of the Chlorophyceae (Nannochloris atomus), and three diatom species (Chaetoceros calcitrans forma pumilum, Chaetoceros gracilis, Skeletonema marino). We found that the limpet larvae ingested phytoplankton over a wider range of cell sizes and ate at higher rates on each...

Etudes sur les mortalites larvaires de la coquille st Jacques Pecten maximus en ecloserie ArchiMer
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 ArchiMer
Dao, Jean-claude; Barret, Jean; Carval, Jean-pierre; Connan, Jean-paul; Corre, Christian; Devauchelle, Nicole; Fleury, Pierre-gildas; Laurent, Pascale; Mazuret, Michel; Miner, Philippe; Mingant, Christian; Muzellec, Marie-louise; Robert, Rene.
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 ArchiMer
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.
