What is the lowest temperature for fishing crucian carp in winter?

The lowest temperature can't be found in China for the time being. You can fish in winter in the south and Harbin in winter.

Low water temperature does not mean that the temperature under the ice is also low. The water under the ice is generally above zero, and fish tend to be warmer. When it is cold, you should fish deep, not very cold, but shallow. Therefore, people usually fish crucian carp at a depth of about 2 meters in winter, and choose a sunny place at a higher temperature every day.

I don't know what fish are mainly caught in winter in the south. In winter in the north, most people catch crucian carp, and occasionally carp. The temperature in winter is not critical to some extent. When the temperature is generally stable, the air pressure has a great influence on fish, and so does it in summer. For example, at noon in summer, the water meter is too hot, and many fish are submerged in deep water, but there are few fish mouths at noon in summer. In addition, the weather is hot, everyone is resting, and the fish are almost resting. But if the air pressure on the water surface rises and the oxygen content in the water drops (for example, on the eve of a thunderstorm), fish will be just like people. On the contrary, the same is true in winter, but the change of air pressure is generally accompanied by the change of weather. If you catch more, you will know what kind of weather conditions are less.
