Abstract:Seven-day-old larvae of Schizothorax wangchiachii with average body weight of(15.5±1.65)mg were randomly divided into five treatments with tubifex’s microencapsulated feed substitute at levels of 0% (0% MF) , 25% (25% MF) , 50% (50% MF) , 75% (75% MF) and 100% (100% MF) to examine the effects of the substitute feed (MF) on the growth, survival rate of larval Schizothorax wangchiachii through determination of its total length, body weight, specific growth rate ( SGR) and survival rate. The results showed that the descending order of specific growth rate in five different substitute levels was expressed as 0% MF(5.73± 0.08)>25% MF(4.80± 0.28)>50% MF (4.67±0.28)>75% MF(4.18±0.51)>100% MF(3.13±0.20)and the descending order of survival rate in five different substitute levels was expressed as 75% MF(77.83±6.11%)>50% MF(76.50±4.35%)>25% MF(71.33± 4.01%)>100% MF(70.00±3.96%)>0% MF(64.00±6.61%). Comprehensive analysis shows that it is feasible to partially substitute microencapsulated feed for ubifex in the breeding of Schizothorax wangchiachii, and 25%-50% of the substitution level can guarantee faster growth and higher survival rate.
