摘要
为减少养虾业排污对近海的污染,防止虾病传播,进行了封闭内净养虾技术试验。在全封闭条件下,采用在池内净化的措施,5个试验池平均亩产对虾65.19kg,比对照组增产70.61%;平均成活率为43.38%,比对照组提高86.98%;投饵系数2.79,比对照组的4.48降低37.72%。
In order to cut down the pollution of the coastal waters,caused by prawn culture industry and prevent shrimp disease from spreading,a study was carried out on technique for farming shrimpwith closed and purged-in pond. Under complete closed condition,taken the measure of purified pondwater,shrimps were farmed in five experimental ponds. The per mu yield of shrimps was 6d. 19kg onaverage,70. 61 % higher than that in the contrastive group, and the average survival rate was43. 38 %, 86. 98 % higher than that in the contrastive group. The feed coefficient was 2. 79, 37. 72%lower than that in the contrastive group.
