Effects of Almix Herbicide on Metabolic Enzymes in Different Tissues of Three Teleostean Fishes Anabas testudineus, Heteropneustes fossilis and Oreochromis niloticus

Abstract

Three Indian freshwater teleostean fishes Anabas testudineus, Heteropneustes fossilis and Oreochromis niloticus were exposed to almix (66.67 mg/l) under laboratory condition for a period of 30 days to investigate the activity of transaminases (alanine aminotransferase (ALT), aspartate aminotransferase (AST)), and phosphatase (alkaline phosphatase (ALP)) in the gill, intestine, heart and muscle tissues. ALT levels showed significant elevation (p H. fossilis > A. testudineus. Therefore, assessment of these metabolic enzymes in tissue systems is important for evaluation of the herbicidal contamination like almix on fish species.
