虾苗循环水集约化中间培育

Medium Intensive Cultivation of Shrimps by Using Closed Circular Water

利用生物膜净化水质的原理 ,配合斜管沉淀 ,自行设计封闭式循环水系统 ,集约化培育大规格虾苗 .试验结果表明 :经 80d培育 ,密度可达 898尾 /m2 ,平均体重达 1.4 8g/尾 ,平均体长 51mm ,折合 1.33kg/m2 .本实验提出了一种对虾苗中间培育的新方法 ,对于对虾养殖防病减灾有一定的现实意义 .

The circular water system is devised to culture intensively the post larvae using bacterial membrane to clean water and making use of inclined tubes to precipitate water.In this system the culture density could reach 898 shrimps/m 2.the average body weight for each shrimp reaches 1.48g(equals 1.33 kg/m 2)and the average body length for each shrimp reaches 51mm in 80 days.The experiments advance a new way for medium intensive cultivation of shrimps and useful for prevention and cure of diseases.
