Diagnosis and treatment of flexibacteriosis of koi carp (Cyprinus carpio koi)

Ornamental fish farming is an intensively developing area in aquaculture. A significant volume of contraband products and the lack of sanitary and quarantine measures is an important problem associated with the development of this knowledge area. The article is devoted to the problem of timely detection and diagnosis of flexibacteriosis of carp, affecting one of the most popular and expensive objects of ornamental fish farming, koi carp. The main causes of fish diseases are natural outbreaks of infections and infection with pathogens from water sources, as well as violations of the rules of transportation and quarantine of imported fish. Timely and constant veterinary control makes it possible to assess the epizootic situation for fish diseases, the degree of pollution of the fishery reservoir and make recommendations for optimizing preventive measures that ensure the epizootic well-being of the fishery reservoir in the conditions of integrated technology. The cultivation of koi by amateurs in private ponds, aquariums poses a danger of introducing infections into other reservoirs, including natural ones, as well as regions where the outbreak has never been recorded. The main task is the prevention of diseases, which can be ensured by monitoring the water quality of the water supply source, as well as the use of a complex of veterinary and sanitary measures, including veterinary control over the transportation of fish, preventive quarantine of imported material and quarantine in dysfunctional farms, preventive disinfection and disinfection of structures, inventory, pond beds; regular ichthyopathological examination of the farm; preventive antiparasitic treatment of fish.
