Última Relations entre le contenu lipidique des ovocytes de Pecten maximus (Mollusque, bivalve) et les performances des larves en élevage ArchiMer Le Pennec, Marcel; Gueguen,. The lipid content of spawned oocytes of Pecten maximus was studied by image analysis of semi -thin histological sections and a lipid index was defined. The female gametes were obtained by thermic stimulations of mature adults scallops from different populations after out of season conditioning or sampled in situ during the spawning season. After fertilization, the larval development was followed. The results reveal a large variability in lipid content of normal oocytes. The lipid content can be regarded as homogeneous inside a spawning but the heterogeneity is greater for wild scallops than for conditioned ones. A strong relationship appears between the lipid index and the hatching success, and the number of abnormal larvae after two days rearing. But no...

SYBIOL, SYstem of BIOmetry of Larvae by image analysis, has been designed for measuring larvae of bivalves in a semi automatic way. The main interest of this tool is to provide more information with the extraction of parameters such as area or equivalent diameter. Our purposes are to describe and evaluate the system which is now operational and used in routine in the mollusc hatchery of Argenton.
