在盐度分别为0、1%、2%和3%的水体中进行奥尼罗非鱼幼鱼的对比养殖.实验结果表明,盐度对奥尼罗非鱼幼鱼的生长具有高度显著的影响(P<0.01);对奥尼罗非鱼幼鱼的成活率和肥满系数无显著的影响(P>0.05);对奥尼罗非鱼幼鱼的总摄食量、饵料系数及粪便中总氮量有显著影响(P<0.01).此外,奥尼罗非鱼幼鱼生长的最适水体盐度为1%.
Comparative culture of juvenile O. niloticus at 0, 1%, 2%, and 3% salinity, respectively, showed that salinity had a highly significant effect on the growth of juvenile O. niloticus (P <0.01). There was no significant effect on the survival rate and plumpness coefficient of juvenile O. niloticus (P> 0.05) (P <0.01) .In addition, the optimum salinity of juvenile O. niloticus for growth was 1%.
