摘　　要：对 2 0 0 3年 6月 2 0日在胶州湾放流的约 13 0万尾南美白对虾 ,放流 (虾苗平均体长、体重分别为 3 .13cm ,0 .3 0 9g)的洄游分布、生长特性及回捕率进行了跟踪调查 ,结果表明 :南美白对虾适宜于胶州湾放流 ,且其生长期主要分布于胶州湾浅水区域 (水深 <5m) ,生长速度快 ,至 8月 2 0日～ 9月 3 0日回捕南美白对虾时的平均体长达到 13 .97cm ,平均体重为 3 5 .5 1g ,回捕率约为 12 .3 5 %。About 1.3 million Penaeus vannamei were released in Jiaozhou Bay on June 20, 2003. The average body-length of the released shrimp was 3.13cm, and the average body-weight was 0.309g. The migration, growth and recapture rate of the Penaeus vannamei were investigated. The results show that Penaeus vannamei is mainly distributed in shallow waters where the depth is less than 5m。The growth speed is great. The fishermen begin to recapture the Penaeus vannamei from August 20 to September 30, the average body-length of which is 13.97cm, the body-weight is 35.51g and the recapture rate is about 12.35%. Thus it seems feasible to release Penaeus vannamei in Jiaozhou Bay.
