The Present paper deals with the result of water quality parameters showed there were no significant difference (P>0.05) between the test media and the control. Abnormal behaviour such as imbalance position, secretion of mucus, erratic swimming, respiratory distress flashing and lethargy were observed before death during the exposure period. The exposure leads to a decrease in the levels of erythrocytes, leucocytes, haemoglobin, total protein and an increase in alkaline phosphatase, total bilirubin and plasma glucose when compared with the control. The implications of the findings in relation to the exposed fish and the aquatic environment are discussed. Stinging catfish Heteropneustes fossilis exposed to completely different concentrations of associate organochlorine chemical endosulfan below static conditions, discovered statistically vital increase in sterol contents of liver, brain and gill tissues even at rock bottom concentration (0.0010 mg/l). Fish additionally evoked behavioural changes thanks to chemical toxicity. symptom gave the impression to ensue to fret induced metabolic alterations caused by intoxication.

Endosulfan could be a non-systemic pesticide and is mostly used for agricultural functions, biological science and agriculture. sterol is a crucial element of nice significance in living systems
