? Generally, Koi fish will not freeze to death unless the water temperature is very low. They do not require high water temperature, as long as there is no huge fluctuation, they can survive in general. Even outdoors, when the surface of the pool is frozen, the koi at the bottom of the water can survive.
outdoor koi carp in winter in the north? In winter, when the temperature drops to 0 degrees, the koi carp needs to be transferred indoors as soon as possible, and the indoor water temperature can be kept at about 20 degrees. In autumn, you can feed more food, commonly known as sticking autumn fat. This can not only ensure the strong body of Koi in the coming spring, but also prevent diseases in winter.
If it can not be transferred indoors, it is necessary to do a good job of windproof and heat preservation measures for the fish tank. When the temperature is below 10 degrees, there is no need to feed. If the fish tank is frozen, the ice needs to be broken to ensure that the oxygen of the koi is sufficient. If it is an outdoor fish pond, it is recommended to make a heating pond if conditions permit, and cover the fish pond with a plastic greenhouse, so that there is no problem in the northern outdoor winter. Or you can raise the water level of the fish pond, so that the temperature in the deep part of the fish pond will not be too low. If the pond freezes, it is also necessary to open several holes to allow oxygen to enter the fish pond.
