, koi fish will not freeze to death, but if they stay in an environment below 0 degrees for a long time, they will freeze to death. Therefore, it is very important to keep koi fish outdoors in winter to prevent cold and keep warm.
in winter? The winter in the south is not too cold. Even if the weather is cold, the cold time is relatively short. Koi can grow normally with a little precaution. When the koi is raised in the fish pond in the south, when the cold air attacks, it can be blocked by objects in the north of the fish pond. The procedure in the north is relatively cumbersome.
1. Fish ponds: Fish ponds in the north should be built deeper, preferably 1.8 to 2 meters high. Even if the fish pond freezes in winter, the deep water temperature can provide a warm environment for Koi. If the fish pond is frozen, remember to cut out a few holes to let the koi fish breathe.
2. Bait: Koi is a cold-blooded animal, and its activity will decrease when the water temperature is low in winter. Enzymes in the digestive tract will decrease, so it is not appropriate to feed koi too much at this time, which will easily cause indigestion and not be stuffed to death, but in spring, koi will grow horizontally, and its plump body will not look very beautiful. In winter, when the amount of food is reduced, the excretion of Koi will also be reduced, so that the time interval of water change in winter can be extended accordingly, and new water can be simply injected.
