Description
Since the disappearance of Crassostrea angulata LMK during the epizootics of 1970-72, Crassostrea gigas Thunberg has been cultivated in the Marennes-Oléron basin. The latter, which could reach its commercial size at 18 months (His, 1978), no longer reaches it until 36 months. The harvesting of these oysters as well as their pre-fattening is currently done mainly in the estuaries of the Charente and the Seudre. The growth of C. gigas could be improved by separating the oysters from collectors sooner than usually done and fattening them sooner.
