How to judge the air pressure

Fishing friends all feel this way. In the same weather, the fish chewed all day the day before and didn't bite at all the next day. It seems the weather is the same. How did such a question come back? This is the role of atmospheric pressure! The air pressure is also very important for fishing. Some data show that when the air pressure is high, fish are very active, bite frequently and have a strong desire to eat. On the contrary, when fish don't want to move, they don't want to eat, so they just lie motionless in one place. This is completely different from hypoxia, which will make fish float from the bottom to the surface.
