We investigated the effects of water temperature on physiological parameters in the chicken grunt Parapristipoma
trilineatum. At high temperature, the aspartate aminotransferase (AST) and the alanine aminotransferase (ALT) levels
were increased, suggesting that high temperature induced hepatic damage. In addition, total protein (TP) was high at
high water temperatures, which were considered stressful in the breeding environment. At high water temperatures,
triglycerides (TG) were low due to increased metabolic activity, which decreased the blood TG levels as TG were
used as an energy source. There was no significant difference in the plasma osmolality or the blood ion concentrations
with water temperature. In generally, lysozyme, a factor in innate immunity, increased with water temperature. However,
lysozyme activity tended to decrease with increasing water temperature, but the difference was not significant.
These results suggested that the decrease of biophylaxis at high temperature was affect the growth or survival of the
population.
