摘　　要：为丰富中国扇贝养殖品种,利用从加拿大引进的岩扇贝Crassadoma gigantea种贝,采用人工控温的方法于2016年进行室内人工育苗试验。结果表明:种贝室内培育28 d后自然排卵一次,培育至37 d后用联合刺激法催产,获得约4亿个卵,通过人工授精,卵受精率为90%,孵化率为80%,选育出D形幼虫约3.2亿个;幼虫浮游期持续30 d,成活率为31.4%,采苗后附着变态率为13.2%,变态期持续5~10 d;采苗后培养25 d出池进行海上中间育成,存活率为24.2%。研究表明,岩扇贝在大连人工控温室内育苗和海上中间育成具有可行性。The artificial breeding of rock scallop Crassadoma gigantea imported from Canada was conducted in an indoor pond under control water temperature from January to May in 2016 in order to enrich the scallop species in aquaculture in China. It was found that natural ovulation was observed in the broodstock rock scallops reared in 28 days in the indoor ponds, and that about 400 million eggs were obtained by a combined stimulating method in 37 days and artificially fertilized, with fertilization rate of 9 0 % and hatching rate of 80 %. Total of 320 millions of D- larvae were obtained and pelagic for about 30 days with survival rate of 31.4% , and then metamorphosed into ju-venile scallop in 5-10 days with metamorphic rate of 13.2%. The juvenile scallops were reared in 25 days and then transferred from the indoor cultivation to marine cultivation on the sea with survival rate of 24.2%. The find-ings suggest that it is feasible for artificial breeding under control water temperature in an indoor and marine cultiva-tion of rock scallop in Dalian.
