南美白对虾虾苗的淡化及其对盐度的适应性研究
Research into the desalination of Penaeus vannamei offspring and their adaptability to the water quality of the farming water

摘要: 通过设置不同养殖水体盐度，投放南美白对虾虾苗，经过16 d的养殖，比较其存活率及生长效果。结果表明：投放至人工配置盐度为3左右的海水中，其成活率≥93%，体长增加≥110%；投放至全淡水水体，其存活率≤20%，体长增加≤50%。Abstract: Based on different given farming water conditions,we raised the same desalinated Penaeus vannamei offspring for 16 days and made a comparison of the survival rates together with the growing effects. As a result,when the feeding saltwater with a specific gravity of 1.001,the survival rate was over 93% and the length increase rate was over 110%;while those were raised in the pure fresh water,the surviving rate was less than 20% and the length increase rate was less than 50%.
