Abstract: In the present study, adult live specimens of edible freshwater catfish, Clarias batrachus were procured from local fish market at Hambran road, Ludhiana, Punjab from December 2016 to June 2017 and vital fish tissues (liver, muscle and kidney) were processed for heavy metal analysis and histopathological studies. The observations on histopathology revealed several hepatic lesions viz. Necrosis, infiltration of leukocytes, pyknosis and nuclear pleomorphism. Separation and degeneration of muscle fibres, atrophy of muscle bundles were well-noticed in muscle tissue. Renal alterations included, desquamation of renal epithelium, necrosis and disorganization of renal tubules. The results revealed that the content of toxic heavy metals (arsenic, chromium, cadmium, manganese and lead), which were beyond the permissible limits (WHO/FAO), might have caused the variations in histo-architecture of vital organs i.e. liver and kidney. However, the content of chromium and manganese exceeded the prescribed limits in muscle tissue which might have resulted in histological alterations.
