Four experimental diets using silkworm pupae with 25%, 30%, 35%, and 40% protein levels incorporate with rice bran, mustard oil cake based control diet (25% protein) were formulated. Fish were feed @ 4% of the body weight of the fish. In term of growth (SGR) feed conversion (FCR) and protein efficiency ratio (PER) and protein and lipid deposition in the muscle, silkworm pupae incorporated (43.75%) diet having 40% protein level showed the best performance of the fish in comparison to those with the control diet. The results indicate that silkworm pupae could be the possible low cost animal protein rich alternative source and may be successfully used as supplementary diet for rohu fingerlings.ennullThesis
