在史氏鲟的南移驯养过程中, 其仔稚鱼阶段有多种病害发生, 尤以小瓜虫病最为常见和危害较大, 如不及时地控制会导致仔稚鱼的大量死亡.史氏鲟稚鱼小瓜虫病的防治方法与其它鱼类有很大的区别, 传统有效的治疗鱼类小瓜虫病的药物和方法不能用于史氏鲟稚鱼, 史氏鲟稚鱼对硝酸亚汞、孔雀石绿等传统的药物非常敏感, 这类药物不能用于治疗史氏鲟稚鱼的小瓜虫病.史氏鲟稚鱼对水温的变化也非常地敏感, 承受不了较大幅度的急速水温变化, 因此常用的快速变温治疗小瓜虫病的方法同样不能适用于史氏鲟稚鱼.实验筛选出以50ppm 的福尔马林溶液浸浴治疗史氏鲟稚鱼小瓜虫病是一种安全和有效的方法.“,”Under artificial farming condition, several types of diseases of juvenile Amur sturgeon were found. However, the ichthyophthiriasis was the most familiar disease for the juvenile. Some cure methods for this disease were investigated. Experimental results show that the pharmic endurance of juvenile Amur sturgeon is quite different from that of other species of fishes. So, some traditional cure methods for ichthyophthiriasis are inapplicable for the sufferers of juvenile Amur sturgeon. In this study, soaking the sufferers in the formalin solution with 50ppm of concentration for one to three hours seems the most effective and safe cure methods for the ichthyophthiriasis of juvenile Amur sturgeon.
