报道了几种化学药物以及淡水和高盐度海水治疗大弹涂鱼寄生蛭的实验结果。单独使用 1 0mg/dm3 的敌百虫或 1 0 0× 1 0 -6(V /V)～ 2 0 0× 1 0 -6(V /V)的福尔马林以及混合使用 1 5 0× 1 0 -6(V /V)福尔马林 +0 5mg/dm3 (或 1 0mg/dm3 )的敌百虫对杀灭大弹涂鱼寄生蛭有明显的疗效且较安全。采用淡水浸泡治疗大弹涂鱼寄生蛭是最有效和最安全的方法。高盐度海水浸泡能使鱼蛭脱落 ,但也会导致大弹涂鱼死亡。硫酸铜和“鱼虫绝杀”不宜作为治疗大弹涂鱼寄生蛭的化学药物
Several chemical drugs were reported as well as the experimental results of freshwater and salinity seawater treatment of parasitic leeches. Trichlorfon at a dose of 10 mg / dm3 or formalin at 100xl0 “6 (V / V) to 2000xl0” 6 (V / V) alone was used in combination with a mixture of 150x 10-6 (V / V) Formalin +0 5mg / dm3 (or 10mg / dm3) of trichlorfon has significant efficacy and safety for the killing of parasitic leeches. The use of freshwater immersion treatment of large-billed fish parasitic leeches is the most effective and safest way. High-salinity seawater immersion can cut leeches, but can also lead to the death of the big bounded fish. Copper sulfate and “fish lore lore” should not be used as a chemical treatment of parasitic leeches
