在水温(25.0±0.7)℃条件下,测定了中华鲟仔鱼的初次摄食率,研究了延迟投饵对中华鲟仔鱼的摄食、存活及生长的影响。结果显示,中华鲟仔鱼6日龄时卵黄囊基本吸收完毕,不可逆点出现在延迟投饵第七天(14日龄),开始投喂饵料的最佳时期应在仔鱼开口后的2～3天之内,即第9～10日龄。仔鱼
The initial feeding rate of Chinese sturgeon larvae was measured under water temperature (25.0 ± 0.7) ℃, and the effect of delayed feeding on the feeding, survival and growth of Chinese sturgeon larvae was studied. The results showed that when the Chinese sturgeon larvae were 6 days old, the yolk sac was basically absorbed, and the irreversible point appeared on the seventh day (14 days old) after the delayed feeding, and the optimal period for starting feeding the bait should be 2-3 days after the larvae were opened Within the first 9 to 10 days of age.
