鳝鱼抗病力强,平时很少发病,只有当水质恶化或鳝体受伤时才容易得病。一旦得病,鳝鱼反应迟钝,活动异常,不摄食或白天游出洞外,严重时会引起死亡。所以在高密度饲养过程中,应注意防病治病。如在鳝鱼种入池前用生石灰或漂白粉消毒鱼池,用10ppm漂白粉溶液浸洗鳝种20分钟等。现将几种常见鳝病及防治方法介绍如下: 一、水霉病鳝种放养初期,由于体外受伤后易得这种病。防治方法是经常加注新水,用食盐和小苏打(每立方水体各用4克)全池泼洒,或用孔雀石绿溶液全池泼洒,使其在池水中含量达1～1.5ppm。还可在鳝种入池前,用3％食盐水浸洗1～2分钟,可预防此病。
Eel disease resistance, usually rarely, only when the water quality deterioration or eel injured easily get sick. Once sick, eel unresponsive, abnormal activity, do not ingest or travel outside the cave during the day, can cause serious death. Therefore, in the process of high-density feeding, should pay attention to disease prevention and treatment. Such as eel species into the pool with quicklime or bleach disinfection fish ponds, with 10ppm bleach solution dipping eel species such as 20 minutes. Now several common eel disease and prevention methods are described below: First, the initial stage of stocking eel species, due to easy access to this disease after injury. Prevention and control methods are often filled with fresh water, salt and baking soda (each cubic water body with 4 grams) Quanchiposa, or with the malachite green solution Quanchiposa so that its content in the pool of 1 ~ 1.5ppm. Can also be eel into the pool, with 3% saline immersion 1 to 2 minutes, can prevent the disease.
