暴发性鱼病是近年来严重危害淡水养殖鱼类的一种传染性鱼病,该病流行地区广,发病季节长,患病品种多,死亡率高。为解除该病之危害,我们利用已经分离到的病原菌,针对几十种抗菌药进行筛选试验,配伍成一种新型鱼用药物——败血宁Ⅰ型。通过两年的抑菌、鱼体防治、毒性等试验,表明该药具有抑菌效果好、安全浓度高等特点。现将败血宁Ⅰ型1992年在生产单位应用于防治暴发性鱼病的情况报告如下: 一、防治情况试验塘分布在湖北的沙市、江陵、公安、荆门、松滋、孝感、枝江等七个县市,试验用败血宁Ⅰ型共350公斤,试验总水面达 Outbreak of fish diseases is a contagious fish disease that has seriously endangered freshwater cultured fish in recent years. The epidemic is endemic and has a long season of onset, a large number of illnesses and a high mortality rate. In order to relieve the harm of the disease, we use the already isolated pathogens, dozens of antibacterial drugs for screening tests, compatibility into a new type of fish drug - Septicemia type Ⅰ. Through two years of bacteriostasis, fish control, toxicity and other tests, show that the drug has antibacterial effect, high security concentration characteristics. Now Sepsis I type in 1992 in the production unit applied to the prevention and treatment of fulminant fish diseases are as follows: First, the prevention and treatment of experimental ponds are located in Shashi, Jiangling, Public Security, Jingmen, Songzi, Xiaogan, Zhijiang, etc. Seven cities and counties, the test of Xuexuening Ⅰ total of 350 kg, the total surface water test
