鱼类在水中呼吸主要依靠鳃来完成。鱼鳃的结构复杂又精细,梳子状的鳃瓣由鳃丝和鳃小片组成,在鳃小片中布满微血管。鱼类通过鳃丝的张合来完成呼吸的过程。除气体交换外,鳃还具有排泄废物和调节渗透压的作用。鳃很重要,但它极易被感染而致病。鱼类鳃病快速诊断和有效防治,是水产养殖生产
Fish in the water mainly rely on gills to breathe. Fish gills complex and sophisticated structure, comb-shaped gill flap by the gill filaments and gill pieces, gill pieces covered in micro-blood vessels. Fish through the gill wire Zhang together to complete the breathing process. In addition to gas exchange, the gills also have the role of excreting waste and regulating osmotic pressure. Gills are important, but they can easily become infected and cause disease. Fish gill disease diagnosis and effective prevention and treatment is aquaculture production
