摘要
本研究采用4种不同的饵料进行42d的养殖试验,比较不同营养成份饵料对细鳞仔鱼生长的影响。结果表明,不同饵料对细鳞仔鱼开口驯化和生长具有显著影响,开口阶段,各组间的生长模式方程都能得到比较好的拟合;且仔鱼日增重和瞬时生长率存在不同程度的差异。进口饲料组最终的生长情况最好,其次是水蚯蚓、国产饲料组和混合饵料组。
Forty- two days culture experiment was conducted to compare the effects of four different diets on growth of Brachyrnystax lenok larvae. The result shows that different diets have significant effect on domesticate initial feeding and growth, in initial feeding stage, the growth pattern equations between every group all fitted well;daily weight gain and instantaneous growth rate exist difference in B. lenok larvae was best in imports feed group, next were tubificidae group, domestic feed group, mixed feed group.
