What is the reason for fishing in winter?

Because the density of cold water is high, the density of warm water is low. Without the influence of convection, it is difficult to warm the bottom of water, and the temperature of water surface will be much higher than that of the bottom.

When there is no fish mouth in winter, you can try to change the fishing position. Fishing position in winter is very important. The principle is to find a place for fish to spend the winter. When the weather is clear in winter, the water surface temperature will rise rapidly.

Because the density of cold water is high, the density of warm water is low. Without the influence of convection, it is difficult to warm the bottom of water, and the temperature of water surface will be much higher than that of the bottom. When the weather is fine in early winter, most fish will move on the water with many aquatic plants, that is, bask in the sun and become warm and active.

Therefore, when looking for fishing spots on sunny days in winter, you can find a sunny, leeward and lush place to fish for half a water. At this time, it is usually big crucian carp.

Extended data:

In winter, fishing time is very short. When winter comes and the temperature becomes lower, fish can't hide in deep water, especially in the morning and evening.

Try not to go fishing in the morning and evening. Few fish come out to move at this time. Only when the temperature is slightly higher at noon will a small number of fish come out for activities, so the best fishing time in a day is noon.

In winter, the weather itself is relatively cold, so if you fish, you can choose sunny and slightly warmer weather. In fact, if it is snowy, there will not be many fish coming out, but in fact, winter is also a good time to fish.
