raise fish in rural earthen tanks in winter? Rural earthen tanks need to keep warm in winter, because it is difficult to use some heating equipment in earthen tanks, so only soil methods can be used to keep the temperature. You can dig a big hole in the ground and bury half of the earth tank in it, so that the temperature can be controlled without being completely exposed to the air. In addition, you can also use a quilt to wrap the upper part of the earth tank, but the edge of the place to leave a seam, otherwise it will lead to water hypoxia.
in winter 1. Reduce feeding: First of all, control feeding in winter. Low temperature will affect its appetite, causing it not to like to eat. Feeding too much is easy to spoil the water, and will consume oxygen in the water. It is usually enough to feed once a day, and it should be fed a little bit, and then a little bit after eating, preferably at noon when the temperature is high.
2. Delay the water change: One of the advantages of winter is that the water quality is easier to maintain, so that the water change is not too frequent, and because of the low temperature itself, frequent water change is also a challenge to the health of fish. Usually it can be changed once a week or two, and only about one fifth of it needs to be changed each time.
3. Control the water temperature: If the temperature is too low in winter, it will also be harmful to the health of the fish, so it is necessary to control the temperature properly. The temperature should be kept at least above 5 degrees Celsius. If it is a tropical fish, the water temperature should be at 20 degrees Celsius.
