Summary. Currently, state programs have been developed for the future development of the fisheries sector in the Russian Federation, as well as in other member countries of the Customs Union. This is due to a decrease in production volumes of commercial fish species that occur as a result of the depletion of world reserves at the current trend of population growth. Currently, fish farms operating in the Russian Federation have problems in diagnostics of infectious disease such as fish aeromonosis. Experts have developed a number of new approaches in the diagnosis of this disease in recent years considering the imperfection of methodical instructions for the laboratory diagnostics of disease. Authors analyzed the statistics of morbidity of carp and salmon species by Aeromonas infection in the territory of all federal districts and subjects of the Russian Federation over the past 5 years (from 2014 to 2018) and search for the available methods of laboratory diagnostics of infectious diseases in different species using intensive methods of cultivation. In the course of research, aeromonosis was considered as one of the main and actual diseases in modern fish farming. The analysis of the number of points in Krasnodar region, in which the catch and cultivation of marketable fish is carried out. Retrospective analysis of the number of economic entities engaged in the cultivation of commercial fish from 2014 to 2018 in Krasnodar region is conducted. It was established that cases of detection of the disease are episodic. Authors also studied clinical signs and pathologic changes.

Key words: fish, fish aeromonosis, causative agent, Aeromonas bacteria, laboratory diagnostics, pathogen identification, infectious process, treatment, microflora, intensive cultivation technologies.
