Abstract

Serum biochemical values can be used for monitoring any change in the fish physiological condition and water quality. The aim of this paper was to determine plasma sugar, triglycerides, cholesterol, iron, alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) levels of Liza klunzingeri from the Persian Gulf. Blood sample was collected from the caudal vessel with syringes coated with sodium heparin. Biochemical values were: sugar 110.37 ± 28.46 mg/di, triglycerides 96.82 ± 23.40 mg/di and cholesterol 177.28 ± 40.75 mg/di, iron 104.74 ± 19.08 mg/di, ALP 117.62 ± 34.49 u/l and LDH 1613.00 ± 345.34 u/l. A significant positive correlation (P<0.01) was found between triglycerides and sugar. Triglycerides had a significant and positive relationship with cholesterol (P<0.01). ALP also had a significant and positive relationship with sugar (P<0.01) and triglycerides (P<0.05). LDH correlated positively with sugar, cholesterol, triglycerides (P<0.01) and ALP (P<0.05). The results revealed reverse correlation between iron and cholesterol, sugar, triglycerides, ALP, and LDH (P<0.01). This study contributes to the referential biochemical values of the L. klunzingeri. In further studies, the established reference ranges might be useful for the health assessment of this species.

Key words: Liza klunzingeri, blood, alkaline phosphatase (ALP), lactate dehydrogenase (LDH).
