Due to the alarming occurrence of antibiotic resistance pathogens there is a constant need for an effective alternate way for protection against disease and increased fish production. In this study growth of Molly fish with dietary supplementation of probiotic in an innovative recircularting aquaculture system was studied. In 30 days feeding experiment, the initial and final length of fishes fed with Lactobacillus delbrueckii LABT1 supplemented diet were 0.8±0.03 and 4.2±0.04 cm, showing a length gain of 3.4±0.01cm whereas fishes grown without probiotic diet had initial and final length of 0.8±0.02 and 2.85±0.04 with length gain of 2.05±0.02. The initial and final weights of fishes fed with probiotic were 0.9±0.02 and 3.02±0.02 g with a weight gain of 2.12±0.0 g. The specific growth rate of control fishes and L. delbrueckii LABT1 fed fishes were 5.5±0.64 and 7.9±0.52% with their survival of 100%. Also in the test experiment the fenugreek was grown using fish effluent showed significantly higher plant length. Hence it was concluded that supplementation of probiotic can be used for improving growth performance of fish in recircularting aquaculture system.
