Popis: The fish, Catla catla exposed to an organophosphate Dichlorvos 76% EC (Nuvan) in the laboratory for 10 days in sublethal concentration as 1/10th of 96h LC50 value (1.445 µg/l). The architectural damages of the entry point of the gill, the respiring organ was damaged that impairs the process of respiration. As heterotrophic organisms, the fish depend on the respiring gas for the metabolism which is effected and as a result the growth can be curtailed. The liver the site of metabolism because of its devastating manifestation in it as lesions, all the biochemical interactions are impeded. The exit point of the toxicant, the excretory organ kidney when was defaced in its internal structure, the aminotellic excretory aspect was effected.
