Abstract :

Chromium is considered as a heavy metal, pollutant and as well as essential micro nutrient. Glycogen is a major fuel for aerobic metabolism and place an important role in osmo regulation. The present investigation was carried out to study the effect of chromium on glycogen in selected muscle tissues of a fresh water fish, Labeorohita. The alterations in glycogen activity on exposure to sub lethal concentration (1/10 of LC50, 96hrs) of chromium for 7 days and 30 days was investigated in the present study. In the present investigation cardiac muscle is found to have higher glycogen content compared to the rest of the tissues and the sequence is as follows CM > CR > PR > PP > CW
