摘要
在水温18℃情况下,测定了星斑川鲽(Platichthys stellatus)幼鱼(10.60±0.27 g)在盐度为0、8、16、24、32时的生化组成和能量收支。结果表明8.0盐度组的星斑川鲽幼鱼的粗蛋白和粗脂肪均高于其他盐度组,水分含量低于其他盐度组,而鱼体能值则是盐度0组最高,各组间差异不显著(P>0.05)。另外盐度对摄食能和排泄能有显著影响(P<0.05)。
Studies of the biochemical composition and energy budget of the juvenile starry flounder（Platichthys stellatus） （weighed 10.60± 0.27 g） were conducted on at different salinity levels ： 0, 8,16,24 and 32 at 18 ℃ in fresh water. The results showed that salinity 8.0 group of crude protein and lipid contents were significantly higher than others, respectively but moisture contents is lower than others, the body energy of salinity 0 group is highest of all. There were no significant differences among the treatments（P〉0. 05）. In addition, salinity has an significant effect on energy intake 和 excretion energy, respectively（P〈0.05）.
