Fish offal, comprising viscera of carp, was fermented along with mustard oil cake and rice bran anaerobically by a microbial suspension. The fermented mixture was mixed with fish meal, mineral- and vitamin mixture to prepare three experimental diets: 1) a reference diet (T1), without any fermentation mixture, containing 40 percent fish meal, 2) a diet containing 25 percent fish offal (fermented) and 25 percent fish meal (T2), and 3) a diet containing 30 percent fish offal (fermented) and 20 percent fishmeal (T3). These diets were tested to evaluate growth and biochemical composition of the body of the fingerlings of Labeo rohita and apparent protein digestibility (APD) and intake rate of the diets by the fish. Fingerlings of Labeo rohita, reared for 60 days with the diets containing fermented fish offal mixture (T2 and T3), showed higher growth and higher values of protein and lipid in the carcass than those reared with the reference diet (T1). Fermented fish offal is a viable alternative of fish meal in the formulation of diet for fingerlings of Labeo rohita
