提高海湾扇贝虾池保苗成活率技术研究

On Technique for Raising Survival Rate to Keep the Larvae of Bay Scallop Safely Live in Prawn Pond

利用６５亩虾池进行提高海湾扇贝保苗成活率技术研究，入池稚贝２．１亿粒，经４３天暂养，出池商品苗９７２０万粒，成活率达４６．３％，纯益３５．８４万元。而海上保苗成活率仅为１０％左右。１９９４年２月，专家鉴定认为，本研究居国内先进水平。

Studies on technique for raising survival rate to keep the larvae of the bay scallop safely live in prawn Ponds with the total area of 65 mu were carried out. The result showed that 210 million baby scallops released into the prawn ponds were temporarily cultured 43 days and 97. 20 million commercial young scallops were harvested; the survival rate reached 46. 3%; the net profit was 358. 4 thousand yuan, but the survival rate of the baby scallops keeping in the sea was only 10 %. The result, appraised by experts in Feb. 1994, met the advanced level at home.
