is a very adaptable fish. It has a good adaptability to dissolved oxygen in water. Even if there is not much oxygen in water, loach can survive. When there is very little oxygen in the water, the loach will not breathe with its gills, but with its intestinal wall. At this time, the loach will generally jump out of the water to breathe air, that is, the phenomenon of jumping water, and directly swallow the air on the surface of the water. Therefore, generally speaking, loach farming does not require oxygenation, and the water in the pond should be replaced regularly to ensure the water quality.
However, in some special cases, loach can also be oxygenated. For example, when the loach is still relatively small, its dependence on oxygen in the water will be relatively high. At this time, their function of breathing with the intestinal wall is not perfect. Therefore, if the dissolved oxygen in the water is insufficient, some oxygen can be supplemented artificially. In addition, in peacetime, we can also pay attention to monitoring the oxygen in the water, when the oxygen is seriously insufficient, it can be properly supplemented, although the lack of oxygen will not lead to the death of loach, but after all, it will affect their growth rate.
It has been introduced above. In general, loach breeding does not need to increase oxygen. Only when the loach is young and the oxygen in the water is seriously insufficient, some oxygen can be supplemented artificially. Loach is not the more oxygen the more likely to die, but just the opposite. When the oxygen content in the water is relatively high, the appetite of the loach is higher and the activity is better, so their growth and development speed is faster. Therefore, generally speaking, it is more appropriate to keep the oxygen content in water above 4-5 mg per liter. When the oxygen in the water is insufficient, it can be increased by changing the water, and if necessary, it can be oxygenated.
