The survival, growth performance, feed intake, and feed conversion ratio of cultured Sobaity Seabream Sparidentex hasta in local high temperatures of 24, 28, 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 d, the fish were fed a commercial diet (6-mm pellets, 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°C to 32°C.

高温条件下的 Sobaity 鲷鱼养殖

养殖 Sobaity Seabream Sparidentex hasta的存活率、生长性能、采食量和饲料转化率本研究估计当地高温为 24、28 和 32°C。在每个室内 1 公吨纤维增强塑料罐中对 40 条鱼（平均体重 99 克；平均总长度 17 厘米）一式三份进行实验。在 96 天内，鱼被喂食商业饮食（6 毫米颗粒、46.36% 的粗蛋白和 12.54% 的粗脂肪）。结果表明，Sobaity Seabream 幼鱼的生存和生长性能受温度影响。32°C 组 (158.57 g) 的总增重明显较高，其次是 28°C 组 (138.25 g)，而 24°C 组 (116.98 g) 的增重最低。32°C 组的饲料转化率 (1.62) 明显低于 28°C (1.8) 和 24°C (1.85) 组。32°C 和 28°C 组的采食量明显更高 (6.20–6. 43 g) 比 24°C 组 (5.41 g)。在 32°C 组中，存活率明显较低。条件因素在三个温度之间没有显着差异。总体而言，Sobaity 海鲷养殖在 24°C 至 32°C 的温度范围内是可行的。
