目前,我国淡水鳗养殖多采用室内水泥池养殖,但这种养殖模式在深秋至初春低温季节要烧锅炉保温,在整个养殖周期每个池中均要配备1～2台电动增氧机进行全天候增氧。由于水泥池养殖容量小,水质易突变,发病率高,频繁的发病,频繁地用药,从而导致药残的超标,这是当今制约我国养鳗业发 At present, the cultivation of freshwater eel in our country mostly adopts the indoor cement pond breeding. However, this breeding mode is to heat the boiler in the late autumn to early spring low temperature season. In each pond of the whole breeding cycle, 1 or 2 electric aerators are provided for all-weather Aerobic. Due to the small capacity of the cement pool breeding, water quality is easy to mutate, the incidence rate is high, frequent morbidity, frequent medication, resulting in excessive drug residues, which is now constrained our country eel industry
