How do koi fish survive winter in ponds?
1. Make sure the surface of the koi pond is not completely frozen.
2. If the surface of the fish pond is completely sealed, make holes in the ice.
3. The water in the koi fish pond should be deep enough. If the water depth is higher than 2m, there is no need to worry too much.
4. Add a greenhouse to the surface of the fish pond, get some straw or something, and then cover it with plastic film. At least part of the water surface will not freeze. Winter is cold, so you need to pay special attention when buying fish. In winter, many fish purchased by fish merchants are sick, and there is also the problem of temperature difference. So when choosing fish in winter, be careful.

The water temperature environment is suitable for the growth and reproduction of various pathogens, especially April-May is the peak season of fish disease-"barley yellow." Therefore, everyone should pay attention to taking precautions in advance.
Generally speaking, according to the method described above, whether it is indoor breeding or fish pond breeding koi can successfully winter.
