Abstract: The effects of a commercially available probiotic product containing Bacillus spp, Lactobacillus spp. and Arthrobacter spp. on the growth performance, and protection against Aeromonas hydrophila infection in rohu was studied. Fish were fed diets containing five graded levels of probiotic (0.0, 2.0, 3.0, 4.0, and 5.0 g/kg diet) for 60 days. Dietary probiotic significantly increased the specific growth rate (SGR) as compared to the control diet. Moreover, feeding of supplemented diets containing probiotic resulted in significantly lower mortality (10-30%) against the pathogens Aeromonas hydrophila compared with the control group (90%).
