fish. Different manifestations show that the severity of the situation is different. If it is mild, it can be treated by timely oxygenation. After a period of time, the fish will recover. If it is serious, oxygenation is too late, the fish will not recover. Therefore, we must pay attention to check whether the oxygen pump is working properly, whether the fish have the performance of hypoxia and so on.
anoxia 1. Change water regularly: In the case of normal fish farming, the oxygen in the tank will not be too scarce, because changing water regularly can improve the dissolved oxygen in the water body. Usually, the water change cycle should not be too frequent, which will affect the survival of beneficial bacteria, but also to control the amount of water, preferably not more than a quarter each time.
2. Equipment oxygenation: If you feel that it is too troublesome to change the water regularly, you can also use other ways to oxygenate. The simplest way is to use the equipment. Oxygen pump is an essential oxygenation equipment for many large fish, which usually needs to be turned on 24 hours a day, so that oxygenation can avoid the occurrence of hypoxia.
3, reduce the density: fish will be anoxic, mainly because the breeding density is too large, the number of fish or the volume is very large, so the oxygen consumption will be relatively high, so it is necessary to reduce the density, you can change a little fish tank, or separate the fish, this can also prevent anoxia.
