Abstract
The effect of exposure to sublethal concentrations of Malathion on biochemical activities in the serum of common carp, Cyprinus carpio, was studied during 96 h exposure. Alterations were observed in glucose, total protein, cholesterol, triglycerides, alanine aminotransferase (ALAT), aspartate aminotransferase (AAT), lactate dehydrogenase (LDH), activities in the serum of C. carpio,. ALAT and AAT activity levels in Malathion treated fishes were significantly (p<0.05) higher than the control fishes. The LDH activity in the Carpio after Malathion exposure was two-fold higher (p<0.05) when compared to control. These results revealed that Malathion affects the intermediary metabolism of C.carpio and that the assayed enzymes can work as good biomarkers of Malathion contamination.
