| 摘 要： | 研究了水丝蚓(A)、专用料(B)、蛋黄 基础料(C)、基础料(D)4种不同开口饵料对虹鳟鱼苗生长和存活率的影响,实验时间为13d。实验表明,不同饵料影响虹鳟鱼苗的生长,试验组A组>B组或C组>D组,B组与C组间对全长的变化没有显著差异(P>0.05);其他各组间呈现显著差异(P<0.05)。投喂水丝蚓的A组存活率最高(89.6%),投喂蛋黄 基础料的C组成活率最低(74.5%)。

| Abstract: | A 13-day rearing experiment was conducted in this study.The different initial feeds on growth in total length and survival rate for larval Oncorhynchus mykiss were Limnodrilu(A),a special diet for larval O.mykiss(B),the egg yolk the basal diet(C),the basal diet(D).The result showed that the effect of different feeds on growth of larve ware remarkable with A>B or C>D,there is no significant difference between B and C group for change of total length(P>0.05),but there's asignificant difference for other groups(P<0.05).It had a highest survival rate(89.6%)under the food of Limnodrilu(A),and a lowest survival rate(74.5%)under the food of egg yolk the basal diet(C). |
