Abstract: Toxicants affect biologically active molecules, viz., carbohydrates, proteins and lipids. Carbohydrate, protein and lipid metabolism of fishes are disturbed under the condition of toxic stress and are known to cause increase or decrease in the biochemical constituents of the tissues. In the present study, the biochemical effects caused to Anabas testudineus on exposure to aquatic toxicants present in the Buckingham canal, Chennai, Tamil Nadu, India were investigated. The per cent change recorded in the tissues of experimental Anabas testudineus was found to be in the order of liver > kidney > muscle > intestine > gill; muscle > gill > kidney > liver > intestine; intestine > liver > kidney > muscle > gill in carbohydrate, protein and lipid respectively. The depletion in the metabolites indicated the fact that the whole metabolic pool of the fish gets disturbed/ altered under the toxic stress. Further, the change in the biochemical profile indicates their rapid utilization to provide excess energy to cellular biochemical process in order to cope with the stressed condition.
