摘要

Hybrid grouper ( Epinephelus fuscoguttatus [TG] × E. lanceolatus [GG]) juveniles were evaluated in terms of their blood hematology and biochemical levels after 60 days of exposure to different temperatures (22?°C, 26?°C, 30?°C, and 34?°C) in triplicate (20 fish/tank; body weight 200?±?15?g; length 22.5?±?1?cm). The fish were fed daily with commercial pellets (42% protein, 9% ash, and 11% lipid) or shrimp (42% protein, 9% ash, and 11% lipid). Results showed that the blood hematologic parameters of the fish fed with shrimp at 26?°C were significantly better than those at other temperatures. The lowest stress level measured in terms of glucose (26?±?10?mg dLsup?1/sup) and cortisol concentrations (0.5?±?0.1?ng mLsup?1/sup) after 60 days of the experiment were observed in the fish fed with shrimp at 26?°C compared with those fed with other diets and at other temperatures. Overall, the TGGG hybrid showed the highest red blood cell and total protein counts in fish fed with a shrimp diet at 26?°C, which were healthful and less stressful conditions. Thus, the health of TGGG hybrid fed with shrimp was better than that of fish fed with other diets and at other temperatures. These findings would be useful for further studies on the management of the TGGG hybrid to increase production.
