Carps exposed to infection were investigated objects. The body of aquatic organisms is not a natural reproduction environment of Salmonella, however, as a result of cross-infection, Salmonella bacillus may appear in fish. The use of probiotic additives from living bacteria has become an alternative to the use of antibiotics, probiotics have antagonistic abilities against pathogens. A group of carp yearlings was selected for research in an aquarium installation. The average weight of animal specimen was 900 grams. During the experiment, the main hydrochemical parameters were monitored. Oxygen disturbances were not allowed by using aerators. The temperature of the water was kept at 19–20 ° C. The diet was standard for raising carp and herbivorous fish. The presence of Salmonella bacteria in the control group was revealed in all fish three days after infection. Experimentally established high efficiency of the drug "STF-1/56" in fish farming, as a method of combating Salmonella infection without disrupting the microbial balance of microflora in the intestinal cavity.
