How stressful is it for fishing today?
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 to fish, so 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 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.
