1987～1990年对辽宁省鱼病调查结果表明,主养鲤、鲫塘粘孢子虫病呈上升趋势。为此于1996～2000年在沈阳和辽阳两市部分主养鲤、鲫池塘进行了防治试验。试验采取室内外相结合的方法,对粘孢子虫病的种类、寄生部位和药物及剂量进行了对比试验。结果表明,泼洒0.3×10-6～0.4×10-6敌敌畏乳剂(80%),同时投喂孢子散或0.2‰～0.3‰的敌敌畏药饵3～5d,并适当更换池水,可有效地防治鲤鲫体内外的粘孢子虫病。
The survey of fish diseases in Liaoning province from 1987 to 1990 showed that the myxosporidiosis of main carp and crucian carp pond was on the rise. To this end in 1996 and 2000 in Shenyang and Liaoyang City, part of the main carp and crucian carp ponds were tested. The test adopts a combination of indoor and outdoor methods to conduct comparative tests on the types of myxosporeas, parasitic sites and drugs and dosages. The results showed that sprinkling spores of 0.3 × 10-6 ~ 0.4 × 10-6 (80%) and spore powder or 0.2 ‰ ~ 0.3 ‰ of DDVP baits for 3 ~ 5 days, and the appropriate replacement of water could be effectively controlled Carp crucian in vitro and in vivo myxosporidiosis.
