Abstract: Yeast, a kind of fungal organism mainly divided by budding, is widely distributed in nature and often used in fermentation industry.In aquaculture, beneficial yeast cultures are often used as feed additives, while harmful yeasts are pathogenic to animals in aquaculture, and seriously threaten the output and economic benefits of aquaculture.Therefore, prevention and control of the pathogenic yeasts has become a key problem in aquaculture.It is better to control the pathogenic yeasts in aquatic animals by defining the species, host, transmission route and infection mechanism.In this paper, the main hazards, epidemic situation, transmission routes, detection methods and control methods of pathogenic yeasts in aquatic animals were reviewed.Furthermore, the future research should focus on the epidemiological and molecular epidemiological investigation, the life history and invasion mechanism of pathogenic yeasts, and the development and application of green biological fishery drugs and immune agents were suggested, which provide reference with the prevention and control of pathogenic yeast in aquatic animals.
