鱼生活在水中,靠鳃吸入水中的溶解氧,水中存在的大量病原体生物很容易感染到鳃上。鳃的发病率很高,因此有“养鱼先养水,治病先治鳃”之说。鱼的鳃病种类很多,为了准确诊断、合理用药,笔者凭着多年从事水产工作的经验,将鳃病分为以下6大类,以期为水产业同行提供借鉴和参考。 Fish live in water and rely on the gills to inhale dissolved oxygen in the water. A large number of pathogenic organisms present in the water can easily infect the gills. The incidence of gills is very high, so there are “fish first water, cure gills first” said. Many species of fish gill disease, in order to accurately diagnose and rational drug use, the author with many years of experience in aquatic work, the gill disease is divided into the following six categories, with a view to provide reference for the aquaculture industry counterparts.
