Abstract :A series of experimental studies indicated that copper as a toxicant causes a disturbance in enzyme activity. Stress conditions impose forced anaerobic conditions in the muscle, gill and hepatopancreas tissues of the crab Sesarma quadratum when exposed to two sublethal concentrations of 1/10 [2.8 ppm insert ignore into journalissuearticles values(Exp. 1);] and 1/3 [9.3 ppm insert ignore into journalissuearticles values(Exp. 2);] copper chloride for 21 d. Lactate dehydrogenase insert ignore into journalissuearticles values(LDH); activity was significantly elevated in muscle and hepatopancreas tissues whereas succinate dehydrogenase insert ignore into journalissuearticles values(SDH); activity was suppressed in the crab tissues of the muscle, gills and hepatopancreas for 21 d.Keywords : Copper chloride, SDH, LDH, Sesarma quadratum
