【 摘 要 】

Two experimental groups were applied to measure oxygen consumption (OC) of young grey mullets Mugil cephalus (TL: 27.3±2.1 cm; TW: 187.9±45.8 g) at different temperatures (15, 20, and 25°C). Specimens of fish from seawater (30 psu) and freshwater (0 psu) were transferred in to brackish water (15 psu). Rate of fish OC after rearing in brackish water, showed significant difference (P2/kg/h at temperatures of 15, 20, and 25°C, respectively. In fish from freshwater transferred to brackish water, grey mullets consumed 80.5, 114.4, and 161.5 mg O2/kg/h at 15, 20, and 25°C, respectively (P0.05). It can be concluded, that the OC rate of grey mullets on brackish water has the tendency to increase by temperature rise.
