Black pit fishing weather

The relationship between climate and fishing is 1. When fishing in sunny days with air temperature and water temperature 10 ~ 25℃, the fish have a great appetite and grow rapidly. It is sunny in summer and autumn, and the temperature and water temperature are above 25℃, even above 30℃. Under the scorching sun, the water lacks oxygen instead, and the fish either float their heads or avoid eating in the deep water below 25℃. On a sunny day in winter, there is no wind or secondary wind, and when the temperature and water temperature are below 10℃ and above 4℃, crucian carp, carp and even bream and grass carp are still greedy. If the wind force is 3 or 4, the rate of fish eating hooks will be greatly reduced. If the temperature is below 0℃, the bottom water temperature is around 10℃, and there is no wind or secondary wind, ice fishing is best at noon and 4: 30 pm; For example, in sunny days, the wind force is greater than 4, the temperature is below 0℃, and the underwater temperature under ice is about 10℃, but the fish's hook-eating rate is poor. In summer and autumn, if the southwest wind blows and the weather is sunny, it will be sultry and it will be difficult to catch fish during the day. 2. Fishing in rainy days Fishing in rainy days is more complicated than fishing in sunny days. In spring, summer and autumn, the temperature in rainy days is lower than that in sunny days, and the temperature turns from hot to cold. When it rains, the air is fresh and the dissolved oxygen in the water increases, so fish are particularly active and their appetite is greatly increased. Fishermen often have this experience. Some ponds rarely catch fish, especially those that have not dried up for many years. If you come here to fish on rainy days, you will often get unexpected gains. The process of rainfall can generally be divided into three types: intermittent rainfall, continuous rainfall and intermittent rainfall. According to the amount of rainfall, it can be divided into five types: light rain, moderate rain, heavy rain, heavy rain and thunderstorm. In some areas, there are two special situations: plum rain and rainy season. As far as this rainfall process is concerned, during the intermission of intermittent rainfall, the rate of fish eating hooks is high. Because the air pressure is low before the shower, the fish can't eat or catch; After the shower, a lot of fresh water enters the water with oxygen and food, which makes the fish active and increases their appetite. This is a good time for fishing. When it rains continuously, the rate of fish eating hooks is low. After a few hours, the fresh water in the water increased, which made the fish active and all approached the water for food. At this time, fishing in the rain is very effective. After bathing, the fishing effect is also good. As far as rainfall is concerned, light rain means that the rainfall is less than 2.5 mm within 1 hour or less than 10 mm within 24 hours. In the late period of light rain, fish's food intake increased, and some big fish also grabbed food by the water. At this time, they went fishing in raincoats, and the effect was very good. Moderate rain means that the rainfall is 2.5 ~ 8 mm within 1 hour, or 10. 1 ~ 25 mm within 24 hours, when the fishing effect is good; If the rain clears up, the fishing effect will be better. Heavy rain means that 1 hour rainfall is 8.1~16mm, and 24-hour rainfall is 25.1~ 50mm. Except for wild fish such as catfish and Pelteobagrus fulvidraco, ordinary fish refuse to eat, and anglers can't see the buoy clearly, so it is difficult to grasp the opportunity to lift the pole, and heavy rain leads to health. But after the rain, if the water color is not too turbid and the water flow speed is not too fast, you can fish. Rainstorm means that the rainfall exceeds 1 0mm within1hour, and the rainfall exceeds 50mm within 24 hours. Generally speaking, fishing is not allowed in rainy days. Thunderstorm, also known as thunderstorm, is vulnerable to lightning at this time, and fishing is prohibited; But after the thunderstorm, the weather is clear, the air pressure is high, the water is rich in dissolved oxygen, and the fish have a strong appetite, which is a good time for fishing. The rainy season refers to the period of a year when rainfall is concentrated in the tropical areas at low latitudes. During this period, the water temperature is suitable for fish growth. The rain has stopped, and it is a good time to fish. (Battle Bear-Fishing House)
