| 摘 要： | 在实验室塑料水槽中,观察了不同盐度条件下星斑川鲽(Platichthys stellatus)幼鱼(10.60±0.27)g]的存活率、摄食和生长状况,结果表明,将星斑川鲽幼鱼从盐度为32.0的海水中直接移入盐度为24.0、16.0、8.0、0的低盐水中,在各个盐度下饲养96h后存活率均为100%;经盐度驯化后42d的各组鱼成活率也为100%。盐度0、8.0、16.0组的增重率和特定生长率高于24.0和32.0组;摄食率32.0组最高,16.0组最低;饵料转化效率16.0组最高,24.0组最低,各组间差异不显著(P>0.05)。另外试验表明,低盐度有利于星斑川鲽白化病的康复。

| Abstract: | The survival rate,feeding,growth of platichthys stellatus juveniles were studied at different salinity.The results showed that when the fish were directly translated from salinity of 32 to 0 and more than 0,the survival rates were 100% in 96 hours.If the fish was acclimatized,it was still 100% in 42 days.The fish at salinity of 0～16 grew faster than others; Feeding rate varied as salinity changed,the highest one was at salinity of 32,and the lowest one was 16.As to feed conversion efficiency,the high-est one was at salinity of 16,and the lowest one was 24.There were no significant differences among the treatments(P>0.05).It was found that low salinity was benefit for reducing albinism rate. |
