In the present study metabolic efficiency in the epigean and hypogean populations of Nemacheilus evezardi (Day) was examined. Different experiments were conducted, in both populations, by keeping them either in restricted oxygen or restricted feeding conditions, including starvation. Results clearly show that the rate of oxygen consumption for the hypogean population was significantly less as compared to its epigean counterpart. Further, results also suggest that the hypogean population has a tremendous capacity to maintain its metabolic activity and regulate its body weight under severe conditions characterized by an absence or a limited supply of food.
