The article presents the results of research on the use of a biological product of lactic acid bacteria against the aeronase pathogen in fish. The purpose
of the work is to conduct a therapeutic assessment of the effect of a biological product against the pathogen of fish aeromonosis in laboratory conditions. To determine the antibiotic properties of the developed biological product based on lactic acid bacteria (Lactobacillus fermentum 24c, Pediococcus pentosaceus 10/9k, Lactobacillus paracasei 9c), a laboratory model was created, where the Aeromonas punctata strain known as the causative agent of aeromonosis was taken as an infectious agent. The main object of experiments on the study of the antimicrobial effectiveness of a biological product were carp and carp yearlings. As a result of the influence of a biological preparation against the pathogen of fish aeromonosis, fish mortality was reduced by 40% compared with the group where no biological preparation was administered.
Keywords: lactic acid bacteria, aeromonosis, aquaculture, biological product, antibiotic.
