This study includes the histopathological alterations induced by chronic (20 days) exposure of the fish Clarias batrachus to a sublethal concentrations (20.9 ppm) of Ammonium chloride. Test fishes lost their natural colouration and become almost reddish in colour. Loss of equilibrium before death is a symptom shown all the test fish. The present study therefore points towards a major histopathological alteration found in liver, kidney and intestine in response to Ammonium chloride toxicity in the fish Clarias batrachus (Linn.). So, it is suggested that more suitable to culture at water fertilizer, ammonium chloride concentration of < 20 mg/l for optimum growth performance and survival rate than other water conditions.
