Essais de decontamination des huitres Crassostrea gigas en bassin par renouvellement et circulation de l''eau ArchiMer
Faury, Nicole; Masson, Daniel; Ratiskol, Jacqueline.
The germs decreasing of artificially contaminated oysters Crassostrea gigas has been studied in experimental tanks similar to a shellfish depuration plant, without any chemical or physical water treatment. The oyster were treated by three different water management pattern, compared to a control tank and the germs decreasing studied by MPN method of fecal Coliforms and Streptococus. As a result: 1) it appaears somewhat difficult to conclude in this first attempt about the most efficient treatment. 2) the most important factor in shellfish depuration working is obviously the physiological activity (and stage) of the animals.

de Moussac, G..
Le present rapport resume et synthetise les donnees des principales publications concernant la biologie des peches artisanales aux Seychelles, depuis 1912, en particulier les rapports des prospections et de statistiques de peche. Une premiere partie presente les donnes biologiques acquises aux Seychelles {sensu strioto) sur quelques 58 especes de poissons. Certains resultats non publies (principalement proposes par l'auteur) sont egalement inclus dans ce chapitre. La seconde partie traite des donnes biologiques sur les ressources marines vivantes, autre que les poissons, a savoir les crustaces, les coquillages et les algues.
