摘要
本文较详细地介绍了利用海水与海水晶进行20亩池塘的淡化养殖南美白对虾的效果对比试验情况。使用海水淡化养殖的池塘,虾苗淡化成活率90.3%,平均亩产364.7kg,养殖成活率 90.2%,亩毛利润为5616.2元;使用海水晶淡化养殖的池塘,虾苗淡化成活率87.6%,平均亩产 353.4kg,养殖成活率88.7%,亩毛利润为5441.6元。试验结果表明,两者在养殖成活率、生长速度、亩产量、饲料系数等方面均表现出无明显的差别。本文还介绍了淡化养殖南美白对虾操作技术, 对养殖生产者具有一定的参考价值。
the paper described the comparative experiment on Penaeus vannamei breeding result by using sea water and salt in ponds, larva desalinization survival rate is 90.3% in sea water ponds with a harvest of 5,470.5kg/ha. ,breeding survival rate 90.2% and gross profit 84,243RMll/ha. Larva desalinization survival rate is 87.6% by using salt with 5,301 kg/ha., breeding survival rate 88.7% and gross profit 81,624RMB/ha.. There is no great difference on breeding survival rate, growth rate, harvest and feeding index. Desalinization technology is presented for culturists.
