Resumo: | The want of C. gigas spat-catching in the Marennes-oleron basin in 1981 can be due to various different reasons which are analysed here. Physico -chemical and trophic factors that can induce variations in the quality of gametogenesis, are successively in comparison with the year 1979 when reproduction was good. The biochemical evolution and a study of gonads slow a lack in maturation in 1981 even during the summer period. Late maturation of gonads bring about physiological consequences which induced mortality of cultivated oysters at the end of winter. A feeble recruit and a decrease of the cultivated stock have economic consequences which here sketched up.
