How much pressure is it to fish in winter in the south?

First, the change of air pressure has an important influence on fishing.

1, the air pressure drops by more than 500 Pa in one day, and the fish are not active or even bite.

2. For one or two days in a row, when the air pressure rises above 500 Pa, the fish becomes active, even biting the hook is going crazy.

3. The change of air pressure has a great influence on the fish. The influence of air pressure on fish should revolve around a word "change". High air pressure is not necessarily beneficial to fishing ―― if the change trend of air pressure is downward; If the air pressure is low, it may be bad for fishing ―― if the air pressure is rising. The air pressure dropped yesterday and continues to drop today. I call it "double drop"; On the contrary, it is called "Shuang Sheng". Shuang Sheng's double drop is relatively large, and it also has a great impact on fish conditions. So we should not only look at the pressure changes in one day, but also look at the pressure changes in a few days. The cold wave came, and on the day when the typhoon came, the air pressure rose sharply, and the fish were particularly active, and the fish almost bit the hook crazily. On the contrary, the day before the cold wave came and the day before the typhoon came, the air pressure dropped sharply, so it was difficult to see the drifting signal. I once summed up a sentence: "The pressure rises sharply and the fish is crazy, but the pressure drops sharply and floats." This has been fully proved by facts. The so-called steep rise and fall here means that the short-term change range is above 7 hectopascals.

4. The change of fish situation is not only determined by the change of air pressure, but also influenced by the change of air pressure and temperature, sunny and rainy days. Is it necessary to fish when the air pressure rises? Is it not good to fish when the air pressure drops? Not necessarily. Because air pressure is only one of the weather factors, there are many weather factors that affect fish conditions-especially the influence of temperature change is very significant.

Second, pay attention to the air pressure, please pay attention to the word "change"

The air pressure does have a lot to do with the catch. But it's not just the pressure, because the terrain and altitude are different all over the country, so the pressure suitable for fishing is different. At high altitude, the air pressure is low, so the air pressure suitable for fishing here will be lower than other places. In fact, whether the air pressure is suitable for fishing, the most important thing is to look at the "change" of air pressure! When the air pressure rises, the greater the amplitude, the more active the fish are and the more frequently they bite the hook. If the air pressure rises to 500 hectopascals in one day, it is definitely good weather for fishing. In addition, in the weather that is not suitable for fishing, fish will move for a certain period of time because the air pressure changes 24 hours a day. When the air pressure rises, this time is the fish machine of the day. Therefore, when you pay attention to air pressure, you must pay attention to "change"! Sometimes fishing friends often say that when bad weather breaks out, people actually seize the time when the air pressure rises. Air pressure determines the content of dissolved oxygen in water, and high air pressure has high dissolved oxygen. However, the influence of temperature on the amount of dissolved oxygen in water far exceeds that of air pressure, and low temperature and high dissolved oxygen will be low. In hot summer, even if the air pressure is high, the dissolved oxygen in water will not be too high. This is one of the reasons why it is difficult to fish in summer. If the temperature is high and the air pressure is low in summer, it will aggravate the decrease of dissolved oxygen in water, which has a great influence on fish feeding. In winter when the temperature is low, the dissolved oxygen in water is generally high and almost saturated due to the low temperature. In other words, the temperature in winter determines the fish to eat bait, and the air pressure has little effect on the fish to eat bait. And the air pressure is generally high in winter.

3. What kind of high pressure weather is suitable for fishing?

(1) M: Although the weather is difficult to predict, we can observe the activities of animals. The activities of many animals are closely related to air pressure, such as dragonflies flying close to the ground, swallows flying low for food, birds no longer singing, and the mountains are silent, indicating that the air pressure is decreasing, so it is difficult to catch fish in this weather.

(2) Look at the weather. Before the thunderstorm, the clouds were very low and the air pressure dropped, which was not suitable for fishing. In foggy days, the water vapor in the air is heavier and the air pressure is lower, which increases the difficulty of catching fish. Cumulus clouds and cumulonimbus clouds appeared in the sky, and the weather turned black. In this weather, fish are very upset. Rarely bite the hook.

(3) The air is crisp in autumn, the autumn wind bursts, and the sky is high and cloudy. Autumn is the "all-weather" fishing season and the second feeding season for fish. In this season, especially when the air is crisp in autumn, it is most suitable for fishing, because temperature, air pressure and water temperature are most suitable for fish activities. They are foraging everywhere, greedy and naturally easy to take the bait.

(4) The famous fishing poem in the Tang Dynasty said: There is no need to return to the oblique wind and drizzle, which means that it is the best time to fish when it rains in Mao Mao. This is because the rain in Mao Mao hits the water, which greatly increases the dissolved oxygen in the water, and the fish breathe enough oxygen, which makes them particularly active and easy to take the bait.

(5) Fish jumps after a thunderstorm. In hot summer and autumn, there are often thunderstorms. After the thunderstorm, the temperature dropped and the dissolved oxygen in the water was sufficient. In addition, rain brings a lot of rubbish and sundries from land into the water. There are plenty of baits, so fish are particularly active in foraging. In this weather, to seize this excellent opportunity, fish are particularly easy to take the bait.

Practice further shows that the absolute value of air pressure has a great influence on fishing, and the rise and fall of air pressure is the key to fish foraging. Fish are very sensitive to this change, which requires every fishing enthusiast to master this critical atmospheric pressure. It can bring us endless fish. What kind of pressure is suitable for fishing? Air pressure 1002- 1054 mbar is good for fishing; 1006- 1028 millibar is very good, but other fish are not active. (converted into mmHg, 754-79 1 is easy to fish, of which 757-772 is easy to fish)
