车轮虫病是鱼苗的主要病害之一,如不及时防治,常造成鱼苗大量死亡。徐墨耕等(1955年)用硫酸铜和硫酸亚铁合剂(5:2,总浓度为0.7ppm)能有效地杀灭草鱼鳃上的大中华鱼蚤(Sinergesilus major),并指出,对草鱼鳃上的车轮虫(Trichodina sp.)、鳃隐鞭虫(Cryptobia branchialis)等亦全杀死。 生产实践证明,用硫酸铜和硫酸亚铁合剂0.7ppm治疗鱼苗的车轮虫病疗效很高。然而,施药前则必须准确测量塘水的体积,且形状不规则池塘的丈量和计
Rotifera is one of the main diseases of fry, if not timely control, often resulting in a large number of fry deaths. Xu Mugong et al. (1955) effectively killed Sinergesilus major on the gills of grass carp using a combination of copper sulphate and ferrous sulphate (5: 2 at a total concentration of 0.7 ppm) Trichodina sp., Cryptobia branchialis and the like are also killed. Production practice has proved that the use of copper sulfate and ferrous sulfate mixture 0.7ppm fry rodent disease treatment efficacy is high. However, before the application must be accurate measurement of the volume of pond water, and the irregular shape of the pond measurement and total
