鲩鱼幼苗肠道粘孢子虫病是一种危害性很大的病害。它常与车轮虫病同时并发,往往使人误认为足寄生性鳃病,结果不易获得治疗效果,从而导致鱼苗大批死亡。我们鱼苗场近几年来鲩苗培育成活率下降,1973年总成活率仅10%左右,其主要原因就是粘孢子虫病所致。因此,防治粘孢子虫病就成为提高鲩苗培育成活率的关键。 Mucous spleen miliary conidia is a very harmful disease. It often concurrency with rickettsia, often make people mistaken for foot parasitic gill disease, the result is not easy to obtain the therapeutic effect, resulting in a large number of fry deaths. In recent years, we have reduced the survival rate of seedling cultivation in the fish field. In 1973, the overall survival rate was only about 10%. The main reason for this is the result of myxosporidiosis. Therefore, the prevention and treatment of visceral sporozoites has become the key to improve the survival rate of seedling cultivation.
