For fishing, whether the fish is good or not is most directly related to the weather, and it can also be said to be related to the temperature and air pressure. The air temperature affects the water temperature, and the air pressure is the most important factor in the level of dissolved oxygen in the water. Fish have the optimal feeding temperature, usually between fifteen and twenty-five, too high or too low will cause the fish to eat poorly. Dissolved oxygen is related to air pressure, but the need for dissolved oxygen in fish is also related to water temperature. So there is such a saying, fishing is about temperature.
1. Temperature
Air temperature is the most critical factor affecting water temperature, when the water temperature is too high or too low, the fish will eat less, and the fish will naturally be difficult to catch if they eat less. Therefore, it is not easy to catch fish in summer and winter, but it is easy to catch fish in spring and autumn, because the more suitable the temperature is, the more fish will forage, and the longer the foraging time will be. However, the factors that affect the water temperature are not only related to the air temperature, but also related to the wind, water depth, water flow, light and other factors. The deeper the water, the lower the water temperature, but when the temperature is extremely low, the deeper the water, the higher the water temperature, which is the reason for the depth of winter fishing. The water temperature of the living water is lower, and the water temperature is lower in the upwind position and downwind position than in the sheltered position.
In the spring and autumn seasons, when the temperature is neither high nor low, less attention is paid to the temperature, which is caused by suitable climatic conditions. Spring and autumn can be fishing shallow water, so more important is the impact of light intensity on whether to dare to shallow water, the less strong the light, the more dare to approach the shallow water, these two stages of rainy and foggy weather fish will be easy to catch a lot. In summer, when the temperature is too high, you can only fish in the coolest morning and evening stages of the day, and the fish are vigorous but the feeding time is too short. Summer is more suitable for fishing on windy days, rainy days, after heavy rains, and after thunderstorms. The temperature is too low in winter, pay attention to whether the water temperature is stable, the water temperature is unstable and the fish do not open, so it is best to fish for cloudy and foggy days, sunny days with large temperature differences and strong winds, in fact, the fish situation in winter is not the best.
2. Air pressure
Air pressure affects the level of dissolved oxygen in water, but air pressure is not the only factor in the level of dissolved oxygen. When dissolved oxygen is high, the fish is full of activity and eats a lot more. However, when dissolved oxygen is insufficient, fish may even die. Dissolved oxygen is related to air pressure, water temperature, wind, currents, aquatic plants, and algae. The air pressure is high, the dissolved oxygen in the living water is high, the dissolved oxygen in the windy weather is high, the water temperature is low, the dissolved oxygen is also high, the algae and aquatic plants in the water will release oxygen during the day, and will absorb the oxygen in the water at night, so generally speaking, the dissolved oxygen in the water is high during the day and low at night. The demand for dissolved oxygen in fish is also related to activity, which in turn is related to water temperature. When the water temperature is low, the fish is not active enough and does not require much dissolved oxygen. Moreover, the water temperature is low, and the water's own dissolved oxygen is certainly not low. This is why in winter and early spring, the phenomenon of anoxic turning over in high-density breeding ponds will not occur.
It is also why in the early spring stage of winter, there is no need to look at the level of air pressure when choosing the weather to go out. Generally speaking, the air pressure on a sunny day is not low, at least within the normal range. The air pressure will be lower on a cloudy day, especially if it is cloudy before rain or snow. The southerly wind pressure is also relatively low, which is the direction of the warm and humid airflow, but the north must be a high-pressure weather. This is also the reason why winter fishing is cloudy and foggy, but summer and autumn are best for fishing north wind days. There are several special weather to pay attention to, after the thunderstorm, the high air pressure and low temperature are the weather that is good for fishing in summer and autumn. After the passage of the typhoon, the temperature plummets and the air pressure rises, which is a rare explosion weather in the early summer and early autumn. Foggy weather with low pressure and high humidity is only suitable for late autumn, winter, and mid-spring when the water temperature is not high. The open air represents a large temperature difference, which is suitable for the summer and autumn seasons when the temperature is high, especially in autumn, which is a sign that the temperature is starting to cool.
Spring, autumn and winter are suitable for fishing cloudy days, and summer is also suitable for fishing if it is cloudy but not stuffy, especially after the rain, so the cloudy days are high in the probability of appearing throughout the year, and the fish are in good condition.
