How stressful is fishing?

How much pressure is best for fishing?

The most suitable air pressure for fishing is between 990- 1005 hectopascals. If there is no oxygen in the water below 990 hectopascals, the fish are uncomfortable in the water and have no appetite, and the fish begin to float. At this time, there is no chance for fishing. You can change to floating fishing or semi-water fishing.

When it is higher than 1005 hectopascals, fish eat less and move less. Even if there are fish in the nest, they may not be hooked, so it is difficult to have a good harvest. When the air pressure rises, especially these two days, the fish will bite the hook crazily.

The correlation between air pressure and fishing is an indisputable fact. There are two main points about the relationship between air pressure and fishing:

1, the weather is sultry, the air pressure is low, and the fish are not active or even open their mouths;

2. When the air pressure becomes higher, especially the day before or on the day when the air pressure suddenly becomes higher, the fish have a high enthusiasm for seeking bait, and the catch is often very rich.

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. In the weather with high air pressure, the greatest influence is the dissolved oxygen in shallow water, and the water beyond a certain depth has little effect. In addition, the degree of dissolved oxygen in water is also different, and there are many cases of floating head and disorderly layer, so the relationship between air pressure and other fishing factors cannot be separated at any time.

Fishing is affected by weather changes and water temperature, which leads to the changeable fish situation and the unstable water level of fish foraging. According to the change of fish situation, the fishing group configuration should be diversified, and the long and short rods should be used together. Once the fish situation changes, it can be used for emergency. However, the tonality of the rod should not be hard, and the choice of fishing rod should be based on the principle of being soft rather than hard.

Cloudy days are depressing, especially before the rain, which is extremely sultry. It is usually impossible to catch fish in this weather. But the sultry and low-pressure weather will be relieved soon after the rain, so it is most suitable for fishing in the rain and after the rain in high temperature season; In foggy days, humidity is high and air pressure is low, so it is not easy to catch fish in some seasons. In fact, it can be seen that there are many clouds and thick clouds. It must be low-pressure weather, and the fish situation is often not very good.

However, it depends on the season. When the temperature is low in winter and early spring, cloudy and foggy days are suitable for fishing. This is because although the air pressure is low at this time, the dissolved oxygen in water is inversely proportional to the water temperature, so the low pressure may not be enough. Moreover, the activity of fish in winter is poor, and there is no high requirement for dissolved oxygen itself. Relatively speaking, sunny days, especially windy sunny days, tend to have high air pressure and fish are relatively easy to catch, especially in high temperature seasons. In fact, there is often no standard for the level of air pressure. After all, different seasons have different requirements for air pressure.

Generally speaking, the fishing pressure in summer is at least 1000 hectopascals, and the higher the pressure, the better fishing. In the low temperature season, it is often not necessary to consider the level of air pressure, but whether the water temperature is stable. Because low temperature and low air pressure will not cause hypoxia, because the lower the water temperature, the higher the dissolved oxygen will be. In the hot summer and autumn season, you must pay attention to the air pressure when you go fishing, especially the day before and on the day when the air pressure suddenly rises, the fish will eat well. There are actually three kinds of weather-related fishing in summer, light rain, heavy rain and cool weather.

If there is cooling weather in summer, it is generally affected by the north wind. Moreover, from the experience, the weather in the north wind indicates high pressure, so it is very good explosion-proof weather to have cool high pressure weather in hot summer and autumn. There is a lot of rain and typhoons in summer. Generally speaking, after a typhoon, the temperature will drop and the air pressure will rise. Therefore, it is a good time to go out when the typhoon crosses the border in summer and the wind becomes smaller. The level of air pressure affects dissolved oxygen in water, but the level of dissolved oxygen in water is not only related to air pressure. Temperature is inversely proportional to water temperature. The higher the water temperature (temperature), the less dissolved oxygen. Dissolved oxygen is also related to wind. In fact, the water meter has the greatest influence on the air pressure, and so does the wind, which will increase the dissolved oxygen of the water meter. The level of dissolved oxygen is also related to still water or running water, which is rich in dissolved oxygen.

Therefore, whether the air pressure is low or not depends on the season first, and usually only pays attention to the air pressure in the high temperature season; If the air pressure is low, but there is wind, the fish can barely catch it. If you choose running water, you may not be unable to catch it. However, air pressure does have a great influence on fish's eating. After entering the summer, fishing becomes more and more difficult. It is easier to catch fish when going out in "selected" weather, so the air pressure must not be ignored. Generally speaking, it is better if the air pressure exceeds 1000 hectopascals.
