欧鳗指环虫是危害欧鳗最大的一种寄生虫病。传统使用的最多是甲苯咪唑,但因多年以来一直运用该药物,使欧鳗拟指环虫对甲苯咪唑表现出惊人的抗药性,如池塘养殖由最初期的0.1ppm 扩大到土池高剂量0.5ppm,有的地方(广东番禺一养殖场)1ppm仍不能杀死!水泥池由0.35ppm 扩大到高剂量2ppm,有的地方(福建省顺昌)甚至3ppm,欧鳗拟指环虫仍不能全部致死,特别是2000年,各地养鳗 European eel finger worm is the most harmful type of a European parasite eel disease. The traditional use of mebendazole, but for many years has been the use of the drug, so that the European euryateromyces parachutes against mebendazole showed astonishing resistance, such as pond culture from the initial 0.1ppm extended to the soil pool high dose of 0.5ppm, In some places (Guangdong Panyu a farms) 1ppm still can not kill! Cement pool expanded from 0.35ppm to high dose 2ppm, in some places (Shunchang, Fujian Province) or even 3ppm, the European eel is not meant to kill worm all the dead, especially In 2000, eel around
