Analysis of the food and feeding habits of a fish is crucial in determining the habitat and behavior of a fish in water bodies and thus ascertaining the feeding preference, thereby minimizing the extent of competition for food. Suggested that the natural food of fishes could be classified into three groups, viz, (a) main food, i.e., the natural food which the fish prefers under favorable conditions and, on which, the fish thrives the best; (b) Occasional food, i.e., the natural food which is said to be wellliked by the fish and is consumed as and when available; and, (c) emergency food, i.e., the food which is ingested by the fish when the preferred food items are not available and on which the fish is just able to survive
