The survival, growth performance, feed intake and feed conversion ratio of the culture of Sobaity seabream Sparidentex hasta in local high temperatures of 24°C , 28°C, and 32°C were estimated in this study. Experiments were conducted in triplicates with 40 fish (99 g average body weight; 17 cm average total length) in each indoor 1-metric ton fiber-reinforced plastic tank. For 96 days, fish were fed a commercial diet (6 mm, 46.36% crude protein, and 12.54% crude lipid). The results showed that survival and growth performance of juvenile Sobaity seabream were affected by temperature. Total weight gain was significantly higher in the 32°C group (158.57 g) followed by the 28°C group (138.25 g), and the lowest weight gain was observed in the 24°C group (116.98 g). The feed conversion ratio (1.62) was significantly lower in the 32°C group than in the 28°C (1.8) and 24°C (1.85) groups. Feed intake was significantly higher in the 32°C and 28°C groups (6.20–6.43 g) than in the 24°C group (5.41 g). In the 32°C group, the survival rate was significantly lower. The condition factor showed no significant difference among the three temperatures. Overall, Sobaity seabream farming is feasible at temperatures ranging from 24–32°C.
