Sobaity Seabream Culture in High‐Temperature Conditions

Abstract

AbstractThe 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.
