Does fishing need to break up the cannon on a cloudy and sultry day in Heikeng?

The first trick: change bottom fishing to floating fishing. When there is a lack of oxygen in the water, many fish that cannot tolerate hypoxia will float to the surface to absorb oxygen, such as crucian carp, silver carp, and bighead carp. Grass carp, Wuchang carp, fish, red tip (Mongolian red), and yellow catfish will stay in a certain swimming layer and still have the desire to feed. At this time, if the fishing bottom is changed to fishing float, the bait hook can be lowered until the fish stay. In the swimming layer, there will still be fish biting the hook. Although it is not possible to find out the depth of floating fishing at once, after many tests, as long as a fish is found biting the hook, it can be seen that there are fish staying in the swimming layer. The second trick: fishing for live water. Dissolved oxygen in water comes from the flow of water. The dissolved oxygen in living water is always higher than that in still water. In the same muggy weather, the hypoxic state of fish in living water is better than that in still water. Therefore, when the weather is sultry and fish in still water do not bite the hook, you should look for living water places to set the hook, such as the inlet and outlet of the reservoir, the drainage channel of the pond, the drainage ditch of the river, and the environment around the aerator. Although these places are not as fast as usual There are a lot of fish, but there will be a harvest after all, which is much better than sticking to still water. The third trick: catch the wind. As long as there is a little wind on the water surface, there will be a small wind at the upwind port and a strong wind at the downwind port. Convection will occur in the upper and lower layers of water, and friction will occur in the flowing water. The amount of dissolved oxygen in the water will naturally increase, and the dissolved oxygen will accumulate in the downwind port. Fish will feel hypoxic and gather in the downwind outlet. In addition, wind and waves will increase the number of plankton and floating natural bait in the downwind area. Fish will also be relatively happy to move and feed in the downwind outlet with high dissolved oxygen. The fourth trick: fishing in grass holes. In hot and hypoxic weather, many fish that are intolerant of hypoxia will float to the surface to move around. Fish that float up are instinctive. Fish hiding in bright water lack a sense of security and need to find an environment with aquatic plants to escape. damage from conspecifics, natural enemies and humans. In addition, fish have the habit of avoiding strong light, tending to weak light, and tending to temperature. Therefore, relatively speaking, the smooth water surface with aquatic plants is much better, and the degree of hypoxia will be relatively lighter. Therefore, when fish do not bite the hook due to the sweltering heat and lack of oxygen, you may wish to make a nest in the gaps between aquatic plants near the shore and try fishing. The shallower the water at the fishing point, the better. It is taboo to fish in waters above 1 meter. Because the shallower the water, the lower the air pressure. ———————————————————————————————————————— Please accept it as a satisfactory answer.
