中文摘要:
      根据1986~ 1995 年在东吾洋放流的97 948 万尾中国对虾种苗资料, 研究了仔虾种苗放流技 术和增殖效果。结果表明, 只要掌握好种苗放流技术, 加强海区管理, 直接放流未经中间暂养培育, 平均体长 在10mm 以上的仔虾种苗, 年平均回捕率可达5. 26%, 增殖效果十分显著。
英文摘要:
      According to the data of 979. 48 million Penaeus orientalis seedlings released in Dongwuyang Bay( an inlet with narrow mouth, situated in eastern part of Fujian Province) from 1986 to 1995, this paper has studied the releasing technique and the enhancement effect of post larvae. It could be concluded that the suitable releasing time is from the last ten days of April to the f irst ten days of May in every year, the suitable water temperature is f rom 16 e to 20 e , the releasing region is from Hanjiang to Hongjiang and the optimum opening date is mid July. The results also showed that if we have a good grasp of the releasing technique, strengthen the management of the region, release the post larvae of no middle culture and get average body length over 10 mm, the annual average recapture rate can be increased up to 5. 26% and the enhancement effect is very remarkable.
