Abstract– Fish and fish products provide low fat resources and are very healthy substitute of red meat. Fish industry is growing very rapidly, it provides a good source of income. Hence, it is necessary to produce healthy quality of fishes. Fishes get affected by many environmental factors such as temperature, humidity, pH etc. Proper handling of the water body is also necessary for the production. In the current study, the effect of above factors and the erratic changes in air breathing catfish Heteropneustes fossilis were studied. The effect of these stressors were studied for a period of two weeks. Subsequent decrease in haemoglobin level and muscle glycogen level was observed. Glycogen content was decreased by 57% when exposed to temperature stress. Haemoglobin level is in relation with erythrocytes count. These erratic changes effects the growth of Heteropneustes fossilis which adversely effects the production.
