To evaluate the efficacy of seven compounds against the cichlidogyriasis of tilapia fish (Oreochromis hornorum), two experiments were carried out. In one, 160 naturally infected fish with a mean burden of 33.4 parasites/animal were used. In another, 1600 fish with a burden of 49.9 parasites/fish were used. Fish were randomly divided into eight equal groups and received three treatments as submersion baths: methylene blue, malachite green, potassium permanganate, sodium chloride, formaldehyde, copper sulfate and triclorfon, and a non-treated control. Five days after the last treatment, all fish were killed and dissected to quantify the remaining parasites. All data were submitted to an ANOVA analysis. All groups compared to the control showed statistical difference (P < 0.01), with better efficacy at higher doses. Sodium chloride, potassium permanganate and triclorfon are highly efficient in the control of cichlidogyriasis of tilapia fish, but care should be taken with the toxicity of the two first compounds.
为评估七种化合物对罗非鱼（奥利亚罗非鱼）车轮虫病的疗效，进行了两项实验。在一项实验中，使用了160条自然感染的鱼，平均每条鱼携带33.4个寄生虫。在另一项实验中，使用了1600条鱼，每条鱼携带49.9个寄生虫。鱼被随机分成八个相等的组，并接受三种浸浴处理：亚甲蓝、孔雀石绿、高锰酸钾、氯化钠、甲醛、硫酸铜和敌百虫，以及一个未处理的对照组。最后一次处理五天后，所有鱼被处死并解剖以量化剩余的寄生虫。所有数据都进行了方差分析。与对照组相比，所有组均显示出统计学差异（P < 0.01），高剂量时疗效更好。氯化钠、高锰酸钾和敌百虫在控制罗非鱼车轮虫病方面效率很高，但应注意前两种化合物的毒性。
