The study was to evaluate the effects of water temperature on growth, feed intake and body composition of juvenile barramundi (Lates calcarifer). Triplicate groups of fish (initial wt:10 g) were reared in recirculating system with five temperature (23 °C, 26 °C, 29 °C, 32 °C and 35 °C) for 30 days. Survival (100%) were the same (p > 0.05) among all treatments. Feed intake and specific growth rate (SGR) were the highest (p < 0.05) in 29 °C and 32 °C rearing group, followed by 26 °C and 35 °C rearing group, and the lowest in 23 °C rearing group. Fish reared in 29 °C and 32 °C show lower feed conversion ratio than other treatments. When the water temperature were 29 °C and 32 °C, body lipid content was lower but protein content was higher than other treatments. The results suggest that the adequate rearing temperature are 29 °C and 32 °C.
