Abstract: The effects of fourweaning foods including soybeanmilk,egg yolk,fairy shrimp and rotifers enriched by green algaChlorella vulgarison growth performance and body composition of larval bulatmai barbelBarbus capitowere investigated in order to explore the optimalweaning food of bulatmaibarbel larvae.The results showed that the fish had increase in body weight and body length since 14 days post hatching(DPH)with the best growth in the fish fed rotiferswhich showed higher survival rate,bodyweight,and body length than those in the fish fed the other foods on 14 DPH,19 DPH and 24 DPH.There were 16.45％of protein and 8.79％of fat in the fish fed rotifers. The fish fed fairy shrimp had body weightof1545.2mg,body length of22.509mm and survival rate of88.7％on 24 DPH,significantly higher than those in the fish fed egg yolk and soybean milk.The larvae had good growth by 14 DPH,and seldom grew later when they fed egg yolk.Theminimal growth and survival rates were found in the fish fed soybeanmilk.The findings indicated that rotifers enriched byChlorella vulgariswasmost suitable as aweaning food,and that the key point for initial feedingwas of14 DPH in bulatmaibarbell larvae,egg yolk being used as a supplement food before 14 DPH.
