Abstract: Running water simulating experiment shows that specific growth rate (SGR) of black snapper (Sabastodes fuscescens) increased deceleratedly with increasing ration, and after increasing to a peak value,the SGRor ecological conversion efficiency (Eg) gradually decreased with increasing temperature and ration.Under experimental condition,the maximal and optimal growth temperature was 16.3℃ and 15.8℃,and the maintenance and optimal ration was 0.79% and 4.10 % of black snapper's weight,respectively.Both SGRand Eg decreased with the increment of body weights.Feeding on small sized fish was beneficial to the growth of black snapper,but did not significantly affect its ecological conversion efficiency.
