With considering the principles of probiotics application in aquaculture, the study was designed as to primarily compare the growth, water quality, disease and survivability of freshwater fishes and shrimps between with probiotic and without probiotic culture systems. A total 28, 60 and 12% farms applied five type of feed probiotics, seven type water probiotics and three type of soil probiotics supplied by the different animal health companies of Bangladesh. Using these probiotics there were significant differences found in case of water quality parameters, growth and survival rate between treated and non-treated ponds. The average body weight and total production were observed to be higher in probiotic treated pond6. 68% fish farmer achieves the productions rate 01-50mon whereas it was 57% only and 250 Mon of 1% farmer. The frequency of occurring several diseases like epizootic ulcerative syndrome, gill and fin rot disease, EMS etc. was significantly lower after application of probiotics in culture system.
