Changes in the glycogen content of the liver, muscle and gonads of the laboratory acclimatized fish Nemacheilus botia exposed to Meothrin was studied. Estimations were made after 24 hrs, 48 hrs, 72 hrs and 96 hrs and 10 days, 20 days and 30 days. The lethal concentrations were obtained at 0.040 ppm (24hrs Lc50), 0.038 ppm (48 hrs Lc50), 0.037 ppm (72 hrs Lc50) and 0.033 ppm (96 hrs Lc50) for Meothrin. But 1/10 of 48 hrs of Lc50 value is 0.0038 ppm glycogen content of all tissues were decreased. The processes of glycolysis in all tissues were maximum. The glycogen loss in the liver, muscle and gonads might be due to the toxic action of the pesticide Meothrin on tissue energy level.
