不能使用没有处理过的井水养鱼原因有两方面。一、未经处理过的井水与普通池水水温相差较大。尤其在夏秋季节更为显著。井水与普通水温度相差10℃左右,当把鱼放入未经处理过的井水中时,鱼会因温差较大不适而死。二、井水含氧量较少,低于鱼正常所需的含氧量5.5mg/e,当鱼放入其中会因缺氧而死去。如果要用井水养鱼,必须进行处理。具体的方法可采用曝气: 就是将井水贮在一大水池中或使井水经过较长
There are two reasons for not using untreated well water for fish farming. First, the untreated well water and ordinary water temperature difference between the larger. Especially in summer and autumn is more significant. Well water and ordinary water temperature difference of about 10 ℃, when the fish into the untreated well water, the fish will die due to large temperature discomfort. Second, less oxygen in well water, lower than the normal oxygen required for fish 5.5mg / e, when the fish into which will die due to lack of oxygen. If you use well water to fish, you must deal with it. Specific methods can be used aeration: well water is stored in a large pool or well water after a long
