在鳗鲡养殖期间,无论是日本鳗鲡还是欧洲鳗鲡,于春季和冬季的低温季节常发生真菌与细菌综合感染而暴发死亡,一般发病水温在22—23℃以下,水温在25℃以上一般不再发生真菌病。引起综合感染的真菌有二种:水霉和鳃霉。细菌种类较多,如假单胞菌、气单胞菌等。水霉感染较易诊断,一般凭肉眼即能判定:于体表创伤处可见水霉菌丝象絮状附于体表,刮取病
During the cultivation of eel, either Japanese eel or European eel, the general incidence of fungal and bacterial infections in the cold seasons of spring and winter, and the death of the outbreak, the general incidence of water temperature below 22-23 ℃, the water temperature above 25 ℃ generally does not occur Fungal disease. There are two fungi that cause a combined infection: watery mildew and gills. Bacterial species more, such as Pseudomonas, Aeromonas and so on. Mushroa infection more easily diagnosed, usually with the naked eye that can be determined: visible in the body surface wounds fungus mycelium floc attached to the body surface, scrape the disease
