摘要
1992年至1994年在大亚湾开展了日本对虾Penaeusjaponicus的放流增殖研究，以探讨恢复业已衰退资源的可行性。标志放流体长53—109mm的日本对虾11188尾，生产性放流体长20—41mm的日本对虾苗640万尾。放流增殖效果明显，标志放流的回捕率为2．91％，生产性放流的回捕率为9．3％。大亚湾内放流的日本对虾，不作季节性远距离洄游，只作季节性短距离的浅水-深水区移动。
To explore the feasibility of recovering the resources of Penaeus japonicns which has declined, stock enhancement was carried out in Daya Bay. From 1992 to 1994, 6.4 million Penaeus japonicus with the body length of 10-41mm were released for stock enhancement experiment in Daya Bay. In addition, 11 188 Penaeus japonicus with the body length of 53-109mm were tagged and released. The experiment obtained desired results. The recapture rate of tagging release is 2.9 percent and that of batch release is 9.3 percent. It's the first bine for penaeus japonicus to be tagged and released in China.
