Six isonitrogenous (50%) and isoenergetic (20 MJ/kg) diets were formulated with 20%, 40% and 60% proportions of SBM substitution of total fish meal. Three diets of fish meal protein were replaced by soybean protein which were supplemented with 0.6, 1.2 and 1.8% of taurine (SBM20+T, SBM40+T and SBM60+T), respectively, or without taurine supplementation (SBM20, SBM40 and SBM60). Each diet was fed to triplicate groups of 20 juvenile snapper (average initial weight 3.1± 0.41g) to apparent satiation three times a day for an 8-week period. The fish fed the SBM40+T diet with a total taurine concentration of 16.3 g kg-1 diet had a significantly greater final weight, specific growth rate, and a lower feed conversion ratio than fish fed the other diets. There were significant differences in feed intake and whole-body composition between fish fed different dietary treatments. Survival was not affected by the experimental diets. Considering growth, feed intake and body composition of red snapper, soybean meal could partially replace fish meal by up to 40% and supplemented with taurine in practical feeds.
