中文摘要	对延迟投饵0~7 d的浅色黄姑鱼Nibea chui仔鱼的摄食、生长与存活进行了研究,结果表明:1)当盐度为24.0~24.8、温度20.5~23.0℃时,仔鱼2日龄开口,于开口当天投饵及延迟投饵1、2、3、4 d,投饵后2 h内仔鱼的摄食率分别为30%、50%、30%、20%、10%,平均每尾鱼的摄食量分别为0.8、1.4、0.5、0.2、0.1个轮虫,延迟投饵5、6 d,摄食率均为0;2)延迟投饵0、1 d的8日龄仔鱼全长无显著差异(P>0.05),而与其它组仔鱼的全长则有极显著差异(P<0.01);3)延迟投饵0、1、2 d仔鱼的存活率相差不大,但延迟3 d以上仔鱼的存活率急剧下降;4)浅色黄姑鱼仔鱼的不可逆点(PNR)出现在仔鱼开口后第3天,开始投喂的最佳时间在仔鱼开口后的2 d之内。; Effects of delayed initial feeding on foraging,growth and survival of larval Chu’s drum(Nibea chui) was investigated in May 2004.The results showed that 1) at a temperature of 20.5-23.0℃ and salinity of 24.0-24.8,the larval mouth opened 2 days post hatching,and the initial feeding rate was 30% at a rate of 0.8 prey per larva in two hours.With delayed initial feeding of 1 day,2 days,3 days and 4 days,the feeding rate was 50%,30%,20% and 10%,1.4,0.5,0.2 and 0.1 prey per larva in two hours,respectively.While the feeding rates of larvae delayed initial feeding of 5 days and 6 days was 0.2) there was no significant difference in the growth of the larvae delayed initial feeding of 0 day and 1 day,while there were significant differences in the other groups.3) The larvae delayed initial feeding of 0 day,1 day and 2 days had no significantly different survival;but the larvae delayed feeding of 3 days had significantly low survival.4) The larvae occurred the point of no return(PNR) at 3 days after the mouth opened,indicating that the optimum initial feeding time for the larvae is within 2 days after mouth opened.; 【作者单位】集美大学水产学院水产生物技术研究所；集美大学水产学院水产生物技术研究所福建厦门361021；福建厦门361021；【作者英文名】HUANG Liang-min, XIE Yang-jie, ZHANG Guang-hou, HU Jia-cai(Fisheries College & Institute of Aquaculture Biotechnology,Jimei Univ.,Xiamen 361021,China)
