The primary point of this work was to examine the impacts of commercial probiotic on the survival and development execution of goldfish Labeo rohita. In this analysis, commercial probiotic was introduced in different diet plans and their dietary impacts were compared with diet that contained no probiotic, which was considered as control. Every treatment was triplicated with 15 fish each and the encouraging preliminary was directed for 30 days. Results demonstrated that, L. rohita significantly yielded higher survival rate when it was supplemented with a basal diet with commercial probiotic. Thus, growth performance of L. rohita including weight gain (WG) and specific growth rate (SGR) were significantly higher in all treatment than the control diet. Feed Conversion Ratio in fishes that fed with diet containing probiotic was significantly lower than control group. In the mean time, total length was not significantly influenced by the administered probiotic. The most noteworthy and optimum growth performance among treatment was seen in fish benefitted from the diet D1, while the least growth performance was recorded in fish diet from the control diet. The supplementation of dietary probiotics could serve as useful ingredients to upgrade their survival and growth performances.
