It is best to play oxygen in fish farming, but if the feeding density is small, it is OK to have little oxygen. Oxygen is only good for fish, but not bad. It is not only beneficial to its breathing, but also can promote metabolism and help maintain water quality. Usually, the oxygen pump should be turned on all day to avoid hypoxia, but if the oxygen consumption is not high, it is ok to turn on it at different times a day.

1, which is beneficial to breathing: The primary benefit of oxygenation is to help fish breathe, because fish live in water and need a certain amount of oxygen. If the dissolved oxygen is too low, it will lead to lack of oxygen and even affect their lives, so oxygenation is still necessary.

2. Maintain water quality: There is sufficient oxygen in the water body, which is helpful to maintain water quality. On the one hand, it can promote the reproduction of nitrifying bacteria, so as to better transform ammonia nitrogen and avoid fish being poisoned. On the other hand, it can also inhibit the growth of anaerobic bacteria, which also has a certain purification effect on water.

3, promote growth: Oxygen can promote metabolism, so the growth rate of fish will be accelerated when dissolved oxygen is sufficient. Moreover, fish also need more oxygen in the digestion process, and with some daily consumption, there are many benefits of supplying oxygen to them.
