【摘要】 <正> 栉孔扇贝Chlamys farreri(Jones et preston)肉细嫩鲜美,营养丰富,经济价值很高,在国外市场上深受欢迎,为海珍品之一。 我所在连续四年进行扇贝半人工采苗试验和两年半人工采苗生产的基础上,于1981年承担了山东省水产局下达的“扇贝大面积半人工采苗生产技术”的研究课题。通过不断的实践和改进,目前已系统地摸索出提高扇贝半人工采苗率的技术措施。更多还原

【Abstract】 1 . This is a report of successful semi-artificial gathering of larvae scallops in years from 1981 to 1983. 2 . 2.47 million gathering bags were cast over the whole County and achieved an exceptional bumper harvest in 1983. The average catch per bag reached about 1000 spats, and a maximum of 6000, the sizes of which were between 0.5 and 1.5 cm. 3 . The best time to cast the gathering bags is when fifty or sixty percent of the larvae grow up to 185 microns in length in the Northern Islands. 4. The proper depth for casting the gathering bags is 3-8 m below the sea surface. 5 . Management should be enforced after the gathering bags were cast into the sea.更多还原
