Asphyxiation Induced Alterations in the Glycogen Content of Snake Headed Fish, Channa Punctatus (Bloch, 1972), Godavari River, Nanded

ABSTRACT Temperature is the dominant ecological factor on all animal lives. The aquatic animals are highly sensitive to the temperature fluctuations. In present work, snake headed fish Channa punctatus was exposed for 24, 48, 72 and 96 hours under stress conditions of temperature. The notable changes in glycogen content were observed and compared with control set. It showed that sudden asphyxia developed in animals facing stress conditions and their normal activities were affected. As a result, the glycogen content was significantly decreased than that of the control. References Bayır A, Sirkecioglu AN, Polat H, Aras M (2007). Biochemical profile of blood serum of siraz C.
