摘要: 利用8个海水池塘陆基围隔,进行了封闭式施肥混养中国对虾与罗非鱼的实验研究.结果表明,在对虾放养密度为0.92~2.36尾·m-2的条件下,对虾成活率为75.72~89.98%,平均为82.40%.产量在11.4~24.1g·m-2之间(养殖期为91d).生产力为0.239g·m-2.d-1.在罗非鱼放养量为0.24尾·m-2(体重100g左右)的条件下,鱼虾的数量最适配比为1:10,中国对虾(体长3.00cm左右)的最适放养量约为2.40尾·m-2.

Abstract: Chinese shrimp (Penaeus chinensis) was polycultured with Taiwan red tilapia (Oreochromis mossambicus×O.niloticus) in 8 fertilized land based enclosed seawater ponds. When the density of shrimps was 0.92~2.36·m-2 ,their survival rate was 75.72~89.98%, the yield ranged from 11.4 to 24.2 g·m-2 after cultured for 91 days, and the productivity was 0.239 g·m-2·d-1. When the density of fish was 0.24·m-2 , the stocking ratio of fish to shrimp was 1:10 , and the optimal stocking density of shrimps was 2.40·m-2.
