海湾扇贝人工育苗已五年有余,我国北方辽宁,山东沿海地区已实现大面积养殖。人工育苗技术也日趋完善,单位水体出苗量从几万发展到几十万甚至上百万。但是,稚贝出池后的海区中间暂养技术仍不够成熟,常出现大量逃苗及死亡现象,保苗率往往只有10～20%,甚至更低。如何提高稚贝在海区暂养的保苗率,已成为当前苗种生产急待解决的重要课题。为此,我们在四年的育苗及养殖技术研究过程中,对如何提高保苗率,加速暂养过程中的生长速度进行了
Bay scallop artificial breeding has more than five years, Liaoning Province in northern China, Shandong coastal areas have achieved large-scale breeding. Artificial seedling technology is also becoming more sophisticated, the unit of water emergence from tens of thousands to hundreds of thousands or even millions. However, the juveniles out of the pool in the middle of holding technology is still not mature enough, often a large number of escape and death phenomenon, the seedling protection rate is often only 10 to 20%, or even lower. How to improve the seedling raising rate of juvenile in the sea area has become an urgent issue to be solved urgently in seed production. To this end, we in the four years of nursery and breeding technology research process, how to improve the seedling rate, speed up the holding process of the growth rate
