How to raise fish in a big vat in the yard for winter and how to raise fish in winter?

In winter, the most difficult thing to raise fish in a big jar in the yard is to control the temperature, because when the temperature drops, the fish will lose their appetite and affect their survival. You can bury half of the fish tank in the soil and cover it with clothes, but don't block all the edges. The circulation of gas must be ensured. Some water should be properly added to the cylinder. Without water, it is easy to freeze. You can also sprinkle some salt in it to prevent this from happening. First, how to raise fish in the big tank in the yard for the winter?

Second, how to raise fish in winter 1, and reduce feeding: First of all, feeding fish in winter must be controlled, because in low temperature environment, the food intake of fish will also decrease. If we feed too much, the unfinished food will become residual bait, thus polluting the water quality. Of course, if the water temperature can be kept high, there is no problem in normal feeding.

2. Postponement of water change: The deterioration speed of water quality is usually related to temperature, which is fast in summer and slow in winter, so water quality can be better maintained without changing water too frequently. If you need to change it every three to five days in summer, you can change it once or twice in winter.

3, pay attention to heat preservation: if you raise tropical fish, you must pay attention to heat preservation in winter, the water temperature can not be lower than 20 C, otherwise the fish will freeze to death. Even for wide-temperature fish, the low temperature should not be lower than 5℃, otherwise it will affect their survival.
