Effects of different initial feeds on growth and survival rate of larval Oncorhynchus mykiss

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 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).
