How about fishing in foggy weather?

You can fish in foggy days, of course, no problem, but it depends on whether it is fog or fog, because fog will make the fish mouth fidgety, and fog will make the fish mouth uncomfortable.

The fog is small, indicating that the relative humidity in the air has just exceeded 100%. As the sun shines and the temperature rises, the water vapor in the air will evaporate continuously. In this process, the water vapor on the water surface will participate in this process together, which will greatly increase the dissolved oxygen on the water surface. So the fog is small, the fish's appetite is unprecedented, and the fish's mouth will be very upset.

Visibility is extremely low in foggy days, either the condensation nuclei of fog are floating objects in the air, and there is fog, or the relative humidity in the air is very high. Even if the sun shines directly and the temperature rises, it is difficult to completely evaporate the water vapor in a short time. Therefore, when the water surface is blocked by fog, the dissolved oxygen is decreasing. So fishing in foggy days, you will find that the fish in the water will float on a large scale. It is precisely because the fog lasts for a long time that there is no oxygen in the water, and the fish will have no desire to eat, and naturally there will be no fish mouth.
