The moment of fishing is fun, but sometimes, we find that the fish doesn't bite the hook and can't catch a single fish. At this time, we may wonder, is it because of the air pressure?Will low air pressure keep the fish from biting, and high air pressure will make the fish bite?In fact, this question is not simple, today, I will share my views with you, I hope to give you some inspiration. 
First of all, we need to understand that the level of air pressure is relative and related to time. For example, where I live, the air pressure in the summer is about 990 hPa, and in the winter it is about 1020 hPa, which is a difference of 30 hPa. However, we cannot say that the air pressure in summer is low and the air pressure in winter is high. In the same way, we cannot say that the air pressure in Guangzhou is high and the air pressure in Hubei is low. Because, fish in areas of low air pressure have adapted to the environment there, and they will not be uncomfortable because of low air pressure, just as people at high altitudes will not be deprived of oxygen. Secondly, we need to know that air pressure is only one factor that affects the bite of a fish, and there are many other factors. For example, although the air pressure in winter is higher than in summer, if the temperature is too low, the fish will not biteAlthough the air pressure in summer is lower than in winter, if the temperature is high, the metabolism of the fish will be strong, the appetite will increase, the aquatic plants will be lush, the photosynthesis will be strong, the oxygen in the water will be more, and the fish will bite the hook. 
In addition, there are factors such as climate, water conditions, fish conditions, bait, etc., which will affect the bite of the fish. We should note that the change in air pressure is an important reason why the fish do not bite. An important feature of the relationship between air pressure and fishing is that when the air pressure rises from low to high, the enthusiasm of the fish to bite will increaseAnd when the air pressure decreases from high to low, the fish's enthusiasm to bite the hook will be weakened, or even not bite. This is because changes in air pressure directly affect the amount of oxygen in the water, and fish are very sensitive to the amount of oxygen in the water, which has been proven by many facts. For example, why is it so hard to catch fish at noon in summer and autumn?This is because at noon, when the temperature is at its highest, the air pressure will gradually drop. So, why is it that after 4 p.m., the fish are easy to catch?It is because at that time that the temperature begins to drop and the air pressure gradually increases. 
Also, why is it that before a thunderstorm, fish are not easy to catch, but after a rain, fish are easy to catch?It is also because the air pressure is low before the rain and high after the rain. This phenomenon of rising and decreasing air pressure can occur at any time in any season, and no matter whether the air pressure is high or low, as long as it is reduced, the fish will not be easy to fish, as long as it is raised, the fish will be easy to catch. Finally, we need to learn how to judge the situation of low air pressure and how to deal with it. Keep an eye on the weather forecast。It depends not only on whether the weather is sunny or rainy, what the temperature is, but also on what the air pressure is. In addition, it is also necessary to pay attention to the temperature difference, the temperature difference is large, the air pressure difference is also large, and it is easy to appear in the period of low atmospheric pressure. Observe the weather. In general, the air pressure on a rainy day is lower than that on a sunny day. Even if it doesn't rain, if the clouds in the sky are thick and dark, the air pressure will be low. Especially when black clouds are pressing down on the city and mountain rain is coming, it must be low pressure. Also, if the weather returns, sauna days, or the sky has dense fog, haze, etc., the air pressure will also be low. Look at the performance of the animals. When the air pressure is low, the person will feel uncomfortable, and sometimes even chest tightness, difficulty breathing, dizziness, fatigue, etc. Many animals have similar sensations and behaviors, most notably dragonflies. Dragonflies rely on their wings to rotate to oppress the air, creating air currents and lifting themselves into the sky. So, if the dragonfly does not fly high, it means that the air pressure is low. 
So, what should we do in the case of low air pressure?In fact, we can do it from the following aspects:Analyze the weather situation. We have to look at what the cause of the depression is, whether it is local or widespread, whether it is temporary or persistent, whether the weather will improve or worsen, and so on. If the entire area is low and shows no signs of improving, then we'd better give up fishing, or not expect too much;If it's just a temporary depression, then we can take a little break and wait for the weather to get better. Change the fishing position. We need to look for some places with high oxygen content, such as flowing water, aquatic plants, downwind outlets, etc., which can increase the vitality of the fish and make them easier to bite. Adjust your fishing method. We need to choose the right fishing method according to the water conditions and fish conditions, such as changing from bottom to bottom floating, fishing half water, fishing floating, etc., which can increase the attention of the fish and make them easier to take the bait. Of course, if the air pressure is particularly low and the lack of oxygen in the water is particularly severe, then these methods may not be very effective, and we can only wait for the weather to change and the air pressure to rise before going fishing.
