Abstract: The effects of delayed initial feeding on foraging,growth and survival development of Acrossocheilius hemispinus larvae were investigated in the 25.4~29.5℃ of water temperature using experimental ecological method.The results showed that:In the opening day,feeding and delayed feeding of 1~12 days,the rate respectively is 0,33.33%,100% (6~11 days),85.71%,76.92%,46.67% and 28.57% after the feeding of larvae feeding within 3 h,while the delayed feeding 12 days larval feeding rate was 0;The highest initial feeding rate of larval emergence at 6~11 days of age,and larvae of PNR occurred at 14 days of age.It showed that the larval have strong ability of tolerance hunger performance that larvae with feeding ability is for up to 11 days;It has no significant difference (P>0.05) delayed feeding of 0~2 days for 30 days of age larvae,but has significant difference with other groups of larvae (P<0.05);Larval survival rate reached 100% which delayed feeding for 0~5 days,but the survival rate decreased rapidly which delayed for more than 7 days,and larval survival rate was 0 when delayed feeding for 9 days.Considering the comprehensive performance of feeding,growth and survival,the fit time to feed the larvae is within 2 days after opening.
