Asian seabass is a potential candidate species in Iran for rearing in pond system because of its fast growth rate, ability to adapt to varying environmental conditions and its demand in domestic as well as export markets. Hence, growth parameters, survival and body composition of Asian seabass (Lates calcarifer, 20.70±0.36 g) was investigated. Experiment was conducted in three 0.5 ha ponds with 3500 fish per pond. Diets were fed to fish five times daily to satiation for 135 days. Temperature and salinity were maintained at 27.36°C, 18.66 ppt respectively, while dissolved oxygen did not fall below 5.7 mg L?1. At the end of the trial, final weight 474.71±7.85 g, FCR 0.98±0.02, SGR 2.29±0.03, PER 2.30±0.05 % and survival 85% was obtained. Also, protein and lipid of body was 21.98±0.60 and 1.99±0.09 percent, respectively. Results show that Asian seabass can be ideal aquaculture candidate species in Khuzestan province.
