摘要
研究了用低盐度地下卤水养殖南美白对虾(Penaeusvannamei)的可行性和养殖模式。结果表明 ,向地下卤水中添加适量的K+,调节Na+/K+比值 ,能明显提高仔虾的成活率 ;通过合理的水质调控 ,获得低盐度地下卤水南美白对虾养殖的高产高效 ,其中精养池平均成活率、平均产量和投入产出比分别比半精养提高25.23 % ,148g/m2和0.
The culture style and the feasibility of the Penaeus vannamei in underground brine water of lowsalinity are studied in this paper.The survival rate of the postlarvae rises obviously with appropriate amount of K + added to the underground brine water to regulate the ratio of Na + to K + .By means of regulating the water quality properly,the Penaeus vannamei culture got a high product with a high efficiency.Compared with semi_culture in the study,it shows the survival rate rises by25.23%,the average product rises by148g/m 2 and ratio of input to output rises by0.49.
