The yearlings of Rohu (Labeo rohita) was fed with commercial pellated feed as T1(Control), feed incorporated with Lactobacillus sporogenes @ 4% as T2, Saccharomyces cerevisiae @ 4% as T3 and both Lactobacillus sporogenes @2% and Saccharomyces cerevisiae @ 2% as T4. The experiment was designed for 120 days in the cement tanks. Feeding was done with probiotics and without probiotics at alternate 15 days. Sampling was done at an interval of 15 days. The samples were analysed to determine the weight gain %, specific growth rate %, FCR, FER of fish. The average initial weight of fish in all treatment was about 44 g. After feeding with probiotic incorporated feed, the weight increased to 150.78±0.68 gm, 176.13±0.75g and 183±0.91g in T2, T3 and T4 respectively as against 102.05±0.99g in T1 (control). The growth in T4 was more due to may be more colony formation of microbe in the gut of fish after 15 days

At last it can be concluded that the fish farmer can benefit from this study as they are not applying the probiotic in a systematic way. The probiotic as Lactobacillus sporogenes and Saccharomyces cerevisiae should be applied @2% each of the applied feed. But only Saccharomyces cerevisiae incorporated feed application @4% of total feed for 15 days may be sufficient to get more production, but not as the both species. This study has been done for only 120 days (4 months). So further research is necessary for the entire culture period. Further study may also be done for multiple species of probiotic microbes application in Aquaculture to meet the cost effective aquafarming
