在淡水养鱼中，团头鲂、鲫、鲢易患暴发性出血病，对生产影响甚大。本课题针对该病的主要病原──点状产气单胞菌（ＡｅｒｏｍｏｎａｓＰｕｎｃｔａｔａ）以多种药物作抑菌试验，筛选出高度敏感的数种药物组合成复方内服药，取名为“鱼乐”。经二年时间，该药在几百公顷养鱼水面中作治疗及预防试验，塘口治愈率稳定在９０％以上。 In freshwater fish farming, bream, crucian carp, silver carp prone to fulminant hemorrhagic disease, a great impact on the production. In this study, Aeromonas Punctata, a major pathogen of the disease, was tested for antibacterial activity with a variety of drugs. A number of highly sensitive drugs were screened to form compound internal medicine named “Fish Music” . After two years, the drug in hundreds of hectares of aquaculture water for treatment and prevention trials, Tongkou cure rate stabilized at 90%.
