笔者根据二十年的生产实践,总结了暴发性鱼病的防治方法,供参考。 一、暴发性鱼病发生的原因 1、未能及时防治寄生虫病。鱼类由于寄生虫的感染,造成体表、鳃、组织等器官表皮破损,为细菌的大量侵入创造了条件。 2、药物施用不当。鱼一旦生病,养殖户往往不经明确诊断,仅根据药品的通用说明书盲目用药,根本不了解药物的性能,不考虑养殖水体环境对药物的影响,造成防治效果差,经常错过最佳防治时机。 3、杀虫、杀菌分离 鱼一旦被寄生虫寄生,鱼施药物将虫杀死脱落,但表皮受伤部分很难马上愈合,极易被细菌感染,引发细菌性病害。
According to twenty years of production practice, the author summarizes the prevention and treatment of fulminant fish diseases for reference. First, the causes of fulminant fish disease 1, failed to prevent parasitic diseases. Fish parasites due to infection, resulting in body surface, gills, tissue damage and other organs of the epidermis, a large number of invasive bacteria to create the conditions. 2, improper drug administration. Once the fish is sick, farmers often do not have a clear diagnosis, only blindly according to the general instructions for drugs, do not understand the performance of drugs, regardless of aquaculture water environment on the impact of drugs, resulting in poor control effect, often missed the best time to prevent and control. 3, Insecticide, bactericidal separation Fish parasitic parasites once, the fish will kill the drug off the pest, but the epidermis part of the wound is difficult to heal immediately vulnerable to bacterial infection, causing bacterial diseases.
