用５种药物治疗剑尾鱼聚缩虫病试验，结果呋喃唑酮无效，硝酸亚汞（１． ２５ ±０． ２５） ｍｇ／Ｌ、硫酸铜酸亚铁（５：２）合剂（８．５±０．５）ｍｇ／Ｌ、甲醛（３０±５）ｍｇ／Ｌ、孔雀石绿（０． ９ ± ０． １） ｍｇ／Ｌ对聚缩虫杀死率均在 ９５％以上；治愈率依次为：（９２．５ ± ２．５）％、１００％、（８７．５±２．５）％、（８２．５±２．５）％；剑尾鱼对药物的敏感性强度为孔雀石绿＞硝酸亚汞＞硫酸铜合剂＞甲醛，安全浓度依次为：０．３２、０．４８、４． １、９．４ ｍｇ／Ｌ。表明治疗剑尾鱼聚缩虫病用硫酸铜合剂（８． ５ ± ０． ５） ｍｇ／Ｌ、甲醛（３０ ± ５） ｍｇ／Ｌ浸泡效果好。
The results showed that furazolidone was ineffective, mercuric nitrate (1.25 ± 0.25) mg / L, and 5: 2 mixture of sulphate 0.5) mg / L, formaldehyde (30 ± 5) mg / L and malachite green (0. 9 ± 0.1) mg / L were all above 95% .The cure rates were (92.5 ± 2.5)%, 100%, (87.5 ± 2.5)% and (82.5 ± 2.5)%, respectively. The sensitivity of the swordtail to the drug was malachite green > Mercuric nitrate> copper sulfate mixture> formaldehyde, the safe concentration in turn was: 0.32,0.48,4. 1,9.4 mg / L. The results showed that the treatment of polygamous Swordtail fish with copper sulfate mixture (8.5 ± 0.5) mg / L, formaldehyde (30 ± 5) mg / L soaking effect.
