Recently the increasing popularity of aquaculture, feed constitute one of the highest operating expenditure in intensive practices. Several attempts have been made to reduce the feed cost by increasing the growth performance by employing suitable feeding strategy in order to maximize utilization of supplied nutrients to cultured fish, by mixed feeding schedule of alternating the high and low dietary protein level diet and optimizing the feeding rate and also by incorporating digestive enzymes in the diet . Feed management in terms of optimization of feeding rate and frequency is become imperative in the culture of marine and freshwater fishes and it has become one of the crucial areas of research in the field of aquaculture. Overfeeding and waste food disrupts the water quality while inadequate food supply has direct impact on production cost.
