Why do fish ponds need to open aerators in winter?

At present, like now, we didn't have much demand for oxygenation at the beginning of December.

Opening the aerator is not only for oxygenation, but also partly for oxygenation. In most cases, it is for the temperature between the upper water and the bottom water to be balanced. In fact, as we all know, in winter, the temperature of the upper water can reach more than 10 degrees or 15 degrees, but it is still very low when it goes down about 30 centimeters or 40 centimeters. The main purpose of opening the aerator is to make its upper and lower water temperatures can be adjusted, because we still need to feed in winter, at least so that the fish won't lose fat. Then in this case, after opening the aerator, its temperature rises, and feeding, the fish will eat better, and its bait coefficient will be relatively low.

Why should the aerator be turned off when feeding?

The key problem is mainly our experience in breeding in recent years. Originally, the fish in this period of time, because its appetite is not very high. If you turn on the aerator, it may directly lead to the fish not eating. Yes, its appetite, it is possible that you turn on the aerator, and the fish directly go down and don't come up.
