The biochemical and physiological activities including food consumption, growth rate, body temperature and other body functions which is influenced by the temperature of surrounding water bodies. The growth and survivability in fish are dependent on defined optimum temperature range. The present work deals with the temperature dependent activity of glycogen metabolite in freshwater cultivable fish Oreochromis mossambicus. The fishes were exposed to different temperatures such as 20°C, 25°C, 30°C 35°C and 40°C for 96 hr exposure. The result reveals that the amount of glycogen activity in the tissues like liver and muscles of fish were steadily decrease at increased temperature as compared to control due to excess energy utilized as anaerobic glycolysis enhanced due to temperature stress as well as at gradual low temperature also showed decreasing trend of glycogen activity because lower temperature slow down the cellular activity
