Lysenko A.A., Ponomarenko Yu.Yu., Beretar I.M., Orlova N.N.

Summary. Gill rot is a widely held fish disease of pond fish caused by pathogenic fungi Branchiomycessanguinis Plehn and B.demigrans Wundsch. This disease detected in many countries around the world, causing mass mortality of fish. In Russia, gill rot previously observed mainly in the southern regions, but a recent deterioration of the epizootic situation. One of the reasons for the active dissemination of branchiomycosis in Russia is active commercial ponds without mandatory veterinary inspection. A prohibition of uncontrolled transportation of fish and fish health laboratory monitoring in fish farms are important factors of prevention. In the case of laboratory confirmation of the diagnosis – a complete ban on the export of fish (larvae) and a complex of recreational activities. At this moment a specific treatment was not developed, so the prevention of fish farms, including estivation and simultaneous cultivation along with mixed-age fish are very important. In order to prevent every 5-6 years spend estivation ponds, systematic cleaning, drying, if possible, freezing of, and disinfect the bed. Also recommended isolated content producers, stocking ponds healthy individuals of self-cultivation, creating immune herds, creating favorable hydrochemical and zootechnical regimes.

Key words: fish diseases, gill rot, branchiomycosis, blood parasites, veterinary control and monitoring, fishponds, estivation.
