牙鲆和大菱鲆作为“第四次海水养殖浪潮”——鱼类养殖的主打品种,养殖面积和产量逐年增长,但由于水质污染、养殖技术、管理等诸多原因,养殖病害较前几年加重,特别是纤毛虫病尤为严重,引起苗种及商品鱼大量死亡,严重者死亡率可达70％以上,甚至全军覆没,给生产造成严重损失,危害很大。根据近几年的生产经验,现将牙鲆、大菱鲆纤毛虫病防治技术与同行探讨如下。 Flounder and turbot as the fourth wave of mariculture - the main species of fish farming, breeding area and output increased year by year, but due to water pollution, aquaculture technology, management and many other reasons, farming diseases than previous years Exacerbations, especially ciliates, are particularly serious, causing a large number of deaths of seedlings and commercial fish. In severe cases, the mortality rate can reach 70% or more, even annihilating the entire army and causing serious losses to production. According to production experience in recent years, now flounder, turbot turbinate disease prevention and treatment technology and colleagues discussed below.
