A study was conducted to investigate the effects of dietary essential amino acid (EAA) concentrations on the spawning performance of Acanthopagrus latus. Broodstocks were fed with three replicates of isonitrogenous and isolipid formulated diets (diet 1, diet 2 and diet 3) with different concentrations of EAA (15.40, 16.88 and 18.14%, respectively) for 138 days. Results showed relative fecundity and percentage of buoyant eggs did not display any significant differences among the three dietary EAA concentrations. Fertilizability and hatchability were significantly higher (P<0.05) in broodfish fed with diet 3. However, lowest percentage of abnormal larvae and highest survival rate in 3 day post-hatching (DPH) larvae were observed in broodstock fed with diet 2. Results showed that the EAA concentration in broodstock diet had considerable effects on reproductive performance of A. latus.
