Air pressure is more or less suitable for fishing.

Air pressure 1002- 1054 mbar is good for fishing; Good at 1006- 1028 millibar, other fish are not active. (converted into mmh754-791,it is good fishing, of which 757-772 is good fishing. )

Grasp the relationship between pressure and fishing 1. When the temperature drops suddenly and the air pressure rises, the fishing effect is often good.

Fish belongs to a temperature-changing animal and is very sensitive to the changes of temperature and pressure in nature. Their forecast of the weather is even more accurate than that of the most experienced weatherman. Fish live on food. After a long period of natural evolution, they can sensitively feel the subtle changes in their growing environment and guide their foraging actions. The sudden drop of temperature and the increase of pressure will increase the comfort, activity and appetite of fish. Second, fish feel the temperature drop, so they fast for food. This is why many fishermen like to go fishing the day before or the day before the cold air.

2. When the air pressure rises, the dissolved oxygen in the water is high, and the fish actively look for bait.

The influence of oxygen on aquatic animals and plants has attracted more attention and research from fishermen. When the air pressure is high, people feel comfortable even if there is no wind, and the dissolved oxygen in the water is also sufficient, so the fish feel comfortable and have a positive feeding state. However, dissolved oxygen in shallow water has the greatest influence in high-pressure weather, and has little influence in waters beyond a certain depth. In addition, the degree of dissolved oxygen in water is different, and there are many cases of floating head and disorderly layer.

The level of air pressure has a great relationship with the appetite of fish for food, because air pressure is directly related to the oxygen content in water. As we all know, fish need oxygen. If the water is rich in oxygen, fish will be very active and have a strong appetite for food. If there is little oxygen in the water, it is difficult for fish to breathe and even endanger their own survival, so how can they have an appetite? When the air pressure is high, the dissolved oxygen in the water is rich and the fish has a strong appetite; When the air pressure is low, there is less dissolved oxygen in the water and the fish are not active.
