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 AB or CD, there is no significant difference between B and C group for change of total length （P0.05）, but theres a significant 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).
