摘要
对青岛市古镇口湾放流日本对虾Penaeus japonicus的生长特性进行了研究。结果表明,雄虾生长较快,而雌虾能达到更大的个体,雌虾体重生长拐点在91d前后,雄虾为77d,合理开捕日期为9月中旬,可适当把放流日期提至6月初。9月中旬前放流日本对虾生长期主要集中分布于5m等深线以内泥沙底质海区。
The growth characteristics of Penaeus japonicus released in the Guzhenkou Bay of Qingdao was studied in this paper. The resuh showed that the male grew more quickly than the female, but the female could reach bigger body sizes. The turning point of the weight growth curve for the female was about 91 days, and about 77 days for the male. We suggested that mid-September would be a preferred starting date for recapture. The optimal releasing date should be ahead of early June. Before mid-September, the released P. japonicus mainly distributed in the area within 5m isobaths and with the bottom of mud-sand.
