Abstract: The effects of feed rich in iron oxide nanoparticles and the probiotic Bacillus subtilis on the growth and development of the fish Labeo rohita were investigated in this study. Depending on the needs of the experiment, different combinations of iron oxide nanoparticles and the probiotic Bacillus subtilis were added to the baseline feed. For ninety days, feeding studies were carried out in triplicate. Fish of approximately similar body weights were randomly distributed in five glass tanks that were continually aired at the Department of Zoology, Bareilly College, Bareilly, Uttar Pradesh, for this experiment. Five concentrations of iron oxide nanoparticles (i.e., 0 mg/kg, 15 mg/kg, 30 mg/kg, 45 mg/kg, and 60 mg/kg) and probiotic Bacillus subtilis (05%, 0.5%, 1%, 1.5%, and 2%) were administered concurrently to these five fish treatment groups. Treatment group T1, which served as the control group, was given a basal meal consisting of 0.0 mg/kg of iron oxide nanoparticles and 0% probiotic Bacillus subtilis. After a 15-day interval, body length and weight were measured to assess the effects of the probiotic Bacillus subtilis and iron oxide nanoparticles (viz 0, 15, 30, 45, 60, 75 and 90 days). Compared to other treatment groups, two treatment groups (T4 and T3) shown superior fish development. In order to improve the effectiveness of fish feed, 1.5% probiotic Bacillus subtilis and 45 mg/kg Iron oxide nanoparticles together in the basal diet of Labeo rohita is effective in aquaculture practices.
