The decreased protein content and enhanced free amino acids level might suggest that the reduced synthesis or increased proteolytic activity or at times both can exist in pesticides exposed fish. The elevation of neutral proteases may indicate the damage caused to the tissues due to impairment of energy supply. The elevated alkaline protease activity may indicate higher protein degradation, since alkaline protease prefer to act on structural proteins of tissues. Therefore, the proteins are denatured leading to more activation of proteases. The activities of AAT and ALAT are enhanced with the following toxic exposure of OC compound resulted in incorporation of amino acid into TCA cycle for energy production. This is further confirmed by the enhanced levels of GDH which is responsible for the incorporation of amino acids into TCA cycle. The overall decrease in protein content and enhanced levels of amino acids transaminases and GDH might suggest the utilization of proteins under stress conditions of the fish
