金鱼为什么张嘴呼吸？

金鱼为什么张嘴呼吸？

金鱼张着嘴的最常见原因是缺氧

水中缺氧的原因：

1，鱼缸小，水少，鱼多，导致水中缺氧

2。水中有许多残留的鱼饵或流出物，已经腐烂，水质变差。需氧细菌与鱼争夺氧气，导致水中缺氧

3。当鱼喂得太多时，鱼的后代会变得旺盛，耗氧量增加，导致水中缺氧

4。天气变化、低气压和溶解氧减少导致水中缺氧

当出现缺氧时，大多数金鱼会张开嘴，让水流过鳃获取氧气，并经常浮到水面，这通常被称为浮头现象。症状出现后，应及时更换氧气或水，为其提供溶解氧

Why does goldfish keep their mouth open to breathe?

The most common reason for goldfish to keep their mouth open is lack of oxygen

Causes of oxygen deficiency in water:

1, small tank, less water, more fish, resulting in lack of oxygen in water

2. There are many residual baits or effluents in the water, which are rotten, and the water quality becomes poor. The aerobic bacteria compete with the fish for oxygen, resulting in oxygen deficiency in the water

3. When the fish is fed too much, the offspring of the fish are exuberant, and the oxygen consumption increases, resulting in oxygen deficiency in the water

4. Weather changes, low atmospheric pressure and reduced dissolved oxygen lead to oxygen deficiency in water

When there is anoxia, most goldfish will keep their mouths open and let water flow through their gills to get oxygen, and often float to the water surface, which is often referred to as floating head phenomenon. After symptoms appear, oxygen or water should be replaced in time to provide them with dissolved oxygen
