Description
Recruitment, marketed yield and cultivated biomasses of oysters Crassostrea angulata and Crassostrea gigas are compared to climatic indices for the period 1885-1984. Temperature plays a role up on the date of spawning but explains only partially the failure of recruitment, which has less influence on the marketed yield than on the total biomass Contrary to the sensitivity of wild molluscan stocks to climatic conditions, yield and biomass of these cultivated stocks are not hightly correlated to the annual and seasonal indices of rainfall and air temperature.
