The study deals with the "Effects of Feed Probiotic (Proteus) on Labeo rohita (Hamilton) Fingerlings.” The trial conducted in triplicate for each treatment diet. During the procedure of 60 days, the fingerlings of rohu (Labeo rohita) were fed on four different probiotics (Proteus), mixed in the basal diet containing rice bran, groundnut cake, fish meal, and mineral mixture. The four different feed ingredients combined with conventional carp diet at 2g/kg, 3g/kg, 4 g/kg, and 5g/kg of feed was used. The control containing rice bran, groundnut cake, fish meal, and the mineral mixture also run separately. These experimental feeds were fed to fishes @ 4% of body weight per day. The growth performance of treatment fishes observed every fortnight, and accordingly, the fishes readjusted. During the experimental period, the water quality parameters were found suitable for fish growth. T3 group of fishes showed a higher value of T.L.C. (35.114×103/µl), T.E.C. (3.35×106/µl) and Hb concentration (10.2g%) as compared to control and other treatments. The results indicated that T4 was the best treatment that realized a significant (P = 0.05) increase in all growth parameters, hematological, and biochemical parameters. According to results, it can be achieved that the inclusion of the commercial probiotic (Proteus) @ 4g/kg in the diet of Labeo rohita is useful to get the best growth fish performance with aqua friendly effects on the environment.
