1. How to spend the winter outdoors when raising koi in northern China 1. Heat preservation: When raising koi in northern China, we must do a good job of heat preservation when spending the winter outdoors. The temperature in winter is low, and the temperature difference between day and night is also very large. If the temperature is lower than 2 ℃ at night, it is best to cover it with straw curtains or reed curtains. After the sun rises the next day, it can be removed, and some heat preservation facilities can be made around it.
2. Feeding: Before winter, high-quality water fleas can be used to feed brocade carp, so that it can accumulate energy in the body and stick winter fat. This can greatly enhance their ability to keep out the cold. Artificial diet can be selected as food, and it is recommended to add foods with high fat content to the feed.
3. Breathability: Snow and ice are most feared in winter. If it snows, the fish pond needs to be covered with straw curtains. Do not lift it immediately after the snow stops, so as to avoid snow and ice entering the pond and causing the temperature to drop. If the water surface is frozen, cut a hole in the ice, so that it can breathe and facilitate the fish to breathe.
2. Can koi be raised in the north?Koi can be raised in the north. Koi is large in size, so it usually needs to be raised in a large fish tank or a fish pond, but it must be deep enough. If the fish pond is too shallow, there is little water in it, and the temperature changes easily, the fish may get sick. Although it is a wide-temperature fish, the temperature change should not be too big. It is best to keep warm in winter. There are many feeds that can be fed at ordinary times, which can be fed three times a day and eaten within five minutes each time.
