Abstract: Green Turtles(Cheloniamydas)were cultured at the water temperature 15, 20, 25 and 30 ℃ for 90 days to study the effects of different water temperature on 17 blood biochemical parameters. Results showed total cholesterol (CHOL) and triglyceride (TG) of cardiac function increased first and then decreased with the increase of water temperature and reached the maximum at 25 ℃, with the values of 3.83±0.30 mmol/L and 0.60±0.08 mmol/L respectively. High density lipoprotein (UHDL) tended to decrease first and then increase. The concentration of creatine kinase decreased with the water temperature increased. Of the liver function, albumin (ALB) and total protein (TP) increased first and then decreased with the temperature rise and reached the maximum at 25 ℃ with the values of 6.47±0.66 g/L and 36.33±1.96 g/L. Other index such as A/G, lactate dehydrogenase (LDH), alkaline phosphatase (ALP), aspertate aminotransferase (AST), alanine aminotransferase (ALT) and total bilirubin (TBIL) showed no significant changes while the water temperature raised (P>0.05). For the index of renal function, the concentration of blood uric (URIC) and creatinine (CREA) decreased while the water temperature increased and the concentration of urea nitrogen (BUN) had no significant change (P>0.05). Integrating the effect rule of water temperature on the plasma biochemistry, green turtles cultured at the water temperature 25 ℃ had a low storage material consumption.
