Colloque sur l'aquaculture - 22 - 24 octobre 1973 - Brest ArchiMer
Laubier, Lucien; Reyss, Daniel.
Ces journées ont permis de préciser les résultats scientifiques obtenus par des années d'efforts poursuivis avec ténacité. Dès sa création en effet, le CNEXO s'est efforcé de susciter la constitution d'équipes de recherches spécialement consacrées à l'aquaculture ; il s'est attaché, en tant que coordonnateur national, à réorienter les programmes d'un certain nombre de laboratoires vers des travaux liés à l'aquaculture, en particulier des études sur la reproduction et la nutrition des animaux marins ; il s'est préoccupé de former le personnel sans lequel cette orientation nouvelle et les expérimentations "sur le terrain" auraient été vides de sens. Des bourses de spécialisation ont été attribuées à des chercheurs et à des techniciens qui ont notamment été...

Comparaison de trois index de qualité de l'huître creuse Crassostrea gigas ArchiMer
Berthome, Jean-paul; Deslous-paoli, Jean-marc; Fernandez-castro, N..
Three indexes of quality of Japanese oyster Crassostrea gigas were studied in 3 lots of oysters bred in the r.1arennes-oléron basin from february to july 1979: condition index of MEDCOF &-. NEEDLER, thickness coefficient of IMAI & SAKAI and external quality coefficient of BERTHOME. These different indexes were correlated within each lot of oysters. The external quality coefficient is always significantly correlated with condition index, while thickness coefficient is correlated with other two only for one lot, but seemes useful to rate oyster growth better.

Note sur l'évolution comparée des coquilles Saint-Jacques d'origine différente en Bretagne Nord ArchiMer
Dao, Jean-claude; Buestel, Dominique; Halary, C..
Different batches of king scallops (Pecten maxinus) have been monitored at two sites in Northern Brittany after their seeding at a size of 25-35 cm. These batches are a combination of indigenous scallops, hatchery juveniles with spawners from Brest, and Irish and Scottish juveniles. Their evolution has been monitored over several years. This document presents the preliminary results of the comparison of their growth, mortality and seasonal behaviour during maturation.

Production artificielle de naissain de coquilles Saint-Jacques Pecten maximus (L.) : Analyse des facteurs affectant la croissance larvaire ArchiMer
Cochard, Jean-claude; Gerard, Andre.
The analysis of the Pecten maximus larval productions carried out between 1982 and 1986 in the framework of the repopulating program of the roadsted of Brest demonstrated the existence of a number of factors affecting larval growth in hatcheries: - Larval growth shows important seasonal fluctuations. It is minimal in February-March (3 to 4 µm.D-1) and maximal in June (6 to 8 µm.D-1). The growth of larvae from conditioned spawners does not differ from that of larvae from mature genitors collected in their natural habitat. Growth is favoured by an unknown factor present in sea water and held with a filtration of 0,2 µm. - The growth of the larvae cultivated in slack water in flat bottom ponds is higher than that of the larvae cultivated in bubbling water in...
