title: Biochemical changes induced by chlorpyrifos, an organophosphate compound in sublethal concentrations to the freshwater fish Catla catla, Labeo rohita and Cirrhinus mrigala.
abstract: Freshwater fishes, Catla catla, Labeo rohita and Cirrhinus mrigala were exposed to sublethal concentration of the pesticide chlorpyrifos an organophosphate pesticide. Biochemical changes in total glycogen, total proteins, lactate dehydrogenase (LDH), alanine amino transferase (ALAT) and aspartate amino transferase (AAT) and nucleic acids, Deoxy and ribose, were estimated in the tissues of fishes exposed to the toxicant chlorpyrifos technical grade. The decrease in total glycogen and proteins over control and increase in selected enzymes, LDH, AAT, ALAT, DNA and RNA values were observed in the three fishes exposed to the toxicant.
