Abstract: The natural and manmade contamination of aquatic environment has become a serious problem for the sustainability of fresh water fisheries sector in India.. Ever increasing water pollution level, especially sodium fluoride (NaF), in natural and inland freshwater reservoir condition has made significant biochemical changes in the fishes. Their toxicity can be assessed by using enzymes as biomarker. These enzymes protect the living organisms from the oxidative stress caused by the sodium fluoride. Therefore, the effect of NaF on the digestive enzyme activity in the tissues (intestine) of Cirrhinus mrigala was investigated. In view of this, the investigations on effects of acute and chronic sodium fluoride toxicity to fish Cirrhinus mrigala have been carried out. The changes in amylase, protease and lipase enzymes of intestine were examined. The study revealed the activity of these enzymes in fish decreased significantly as compared to control.
