Abstract
The study aimed to evaluate the feed supplementation on the growth performance of cultivable Indian major carp, Labeo rohita- initiative in replacing fish meal for sustainable aquaculture. The present experimental approach was designed for analyzing the importance of formulated feeding for a period of 90 days by providing feed supplements in the diet like minor millets comprising dried finger millet, Pearl millet and foxtail millet feed along with normal groundnut oilcake. Control fishes were fed with normal groundnut cake feed. Considerable increase was observed in the body weight, length and growth indices of the experimental fishes fed with millet diets, specifically when all the three varieties of minor millets were provided in combination which is highly recommended for improving the growth performance of fish.
