草鱼出血病是一种病毒性疾病。病鱼体色发黑,离群独游,鳃盖、眼圈周围、口腔内、鳍条基部等充血。采取草鱼免疫注射,可使草鱼成活率提高到90％以上。 1988年,我站在县国营渔场进行了免疫注射对比试验,取得了很好的效果。8月5日～25日,对20亩鱼种池进行了试验对比,其中15亩鱼种池共投放了10～17cm的鱼种7.3万尾,逐尾进行了注射(每尾0.2至0.4毫升)效果达到了90％。而未注射的5亩鱼池共投放鱼种3万尾,尽管采取了多种治疗方法,但成活率仅为30～45％;同时还对5户养鱼专业户进行了不
Grass carp hemorrhagic disease is a viral disease. Sick fish body color black, outlier solitary tour, gill cover, around the eye, mouth, fin base and other congestion. Take the grass carp immunization, grass carp survival rate can be increased to 90%. In 1988, I stood in the County State Fisheries conducted a comparative immunization injection test, and achieved good results. From August 5 to August 25, 20 mu of fish ponds were tested and compared. Among them, a total of 73,000 fish species of 10 to 17 cm were put into 15 mu of fish ponds and injected end-to-end (0.2 to 0.4 ml per tail The effect has reached 90%. The non-injected 5 mu of fish ponds were put on 30000 fish species, despite the adoption of a variety of treatment methods, but the survival rate of only 30 to 45%; at the same time also on the five professional fish farmers do not
