摘要
以平均体重为 2 .72 g的江黄颡鱼鱼种作耐盐性试验 ,其 96h半致死盐度 (96hLC50 )为1 2 .0 0 ;直接将鱼种置于盐度为 32的水体中 ,其平均成活时间 (MST)、5 0 %成活时间 (ST50 )分别为 4 6 .8min和 4 9min。生长试验的结果表明 ,江黄颡鱼鱼种在盐度为 0～ 7范围内可以安全生长 。
In the experiment of the Pseudobagrus vachelli tolerance of salinity, 96 h LC 50 of the fish with weight of 2.72 g was 12‰.MST and ST 50 of Pseudobagrus vachelli was 46.8 and 49 minutes,respectively after transferred into water with salinity 32. Pseudobagrus vachelli could grow naturally in water with salinity between 0‰ and 7‰.The growth rate and survival rate are insignificantly different.
