The effect of endosulfan and its isomers on tissue protein, glycogen, and lipids in the fish Channa punctata

Abstract Changes induced in the total protein, glycogen, and lipid content of some chosen tissues of the freshwater fish, Channa punctata (Bloch), exposed to technical endosulfan and its isomers for 96 hr in a continuous flow of water, were studied. Technical endosulfan significantly decreased the protein, glycogen, and lipid concentration of liver, glycogen of muscle, and significantly increased the protein and glycogen of kidney and protein content of brain. While both isomers A and B caused biochemical changes in many tissues of C. punctata , the changes induced by isomer A were more striking than those induced by isomer B.
