A STUDY OF HISTOPATHOLOGICAL CHANGES IN THE GILL AND LIVER TISSUES OF FRESHWATER FISH HETEROPNEUSTES FOSSILIS EXPOSED TO CYPERMETHRIN TOXICITY
The synthetic pyrethroid, cypermethrin toxicity was studied in fresh water fish 'Heteropneustes fossilis and the tissues like gill and liver were chosen for Histopathological effects by light microscopy, for 4 days and 7 days under sublethal concentrations. No Histopathological effects were observed in control group and 4 days group. Hence 7 days group was selected for the present study. Significant changes in Hepatic cells of liver were observed like cloudy swelling of hepatocytes, vacuolour degeneration, and dilation of sinusoids, Hepatic lesions, and Karyo Lexis. In Gill, oedema, Epithelial lining, curling of lamellae were observed. This study demonstrates the potential of electron microscopy in particular SEM, as a tool for detecting cypermethrin induced damage to liver and surface of gill lamellae.
