The biochemical components like protein, carbohydrate and cholesterol were estimated quantitatively in the tissues of liver, kidney, muscle and gill of control and herbicide treated fishes. The fishes were treated with the sub lethal concentration of 3ppm for 24, 48, and 72 hours. The protein, carbohydrate and lipid level of liver, kidney, muscle and gill of the control fish was very high when compared with the treated ones. In treated fish the protein content of tissues were greatly reduced. Maximum reduction was observed at 72 hours exposure. The carbohydrate and cholesterol content of the tissues are showed similar declining trend at different exposure periods. Studies on the toxic effects of atrazine on fish have shown varied responses according to the type of species and dosages.
