There are many problems to pay attention to when raising koi in winter. If you don't pay attention, it may endanger their health. The first thing to pay attention to is the feeding problem. When the temperature is low, their activity will gradually decrease, and they may stay in one place and do not like to move; Their appetite will also be reduced, do not like to eat; In addition, the activity of their digestive system will be reduced or even stopped.
Combined with the above changes, feeding them in winter must be paid attention to. If the temperature of Koi raised outdoors is reduced to less than 10 degrees, it can not be fed directly. If the koi is raised indoors, the water temperature in winter is not too low, so you can continue to feed, but the number of feeding and feeding amount need to be reduced. It can be fed once a day or once every other day, with less feeding and no residual food in the water.
Koi do not eat in winter, may be because the water temperature is particularly low, they have no appetite. At this time, you can stop feeding in a short time, and then feed it after the water temperature rises. They can also raise the water temperature slowly, and then feed them when the water temperature rises.
