Histopathology of hepatopancreas of freshwater fish, Cyprinus carpio collected from the River Ganga at Allahabad, India
The River Ganga receives pollutants from domestic, agricultural and industrial sources which could affect the health of inhabitants. Present investigation clearly revealed histopathological alterations in the hepatopancreas of freshwater teleost (Cyprinus carpio) inhabiting River Ganga at two different geographical sites viz. Phaphamau and Mawaiya of Allahabad. Reduced pancreatic tissues, pancreatic necrosis and clear vacuolization at the junction of hepatic and pancreatic tissues were some of the drastic alterations evident in histoarchitecture of the pancreas. Fish from the Mawaiya site revealed more severe alterations compared to Phaphamau. Histopathological lesions revealed in present study are similar to those observed in the laboratory exposures of fishes to specific pollutants. The observed alterations-could affect the vital physiological functions, such as absorption, storage and secretion of the hepatopancreas.
