As the temperature and water temperature are at a high level, fishermen avoid the scorching sun. Why?

"Go fishing or on the way" is what fishermen often say, but in fact, fishermen do the same, and nothing can stop them. Even if it's windy and rainy, it's always enjoyable in cold and hot weather. But sometimes the weather is the same as the catch, and you can't get what you want every time. So what's the relationship between sunny and rainy days on fishing?

Fishing on a sunny day Most fishing enthusiasts will choose to go fishing on a sunny day. However, sometimes I think the temperature is good, but the fish is not so good. How to judge the news quality of fish on such a sunny day? Many anglers know that when the temperature and water temperature are between 15 and 25 degrees, the food intake and activity of fish species are the largest. At this moment, their food intake is abundant and their growth and development speed is fast. In summer and autumn, if it is sunny continuously, the temperature will rise very high, and the water temperature will be above 25 degrees or even above 30 degrees. At this time, under the exposure of the hot sun, the underwater oxygen content will drop rapidly, and the fish species will escape to the deep water with the water temperature below 25 degrees. If in clear winter, there is no wind or breeze, and the temperature and water temperature are above 10℃ and 4℃, the temperature under water is higher than that above water. At this time, if the sea area is selected correctly, grass carp, crucian carp, carp and bream will still eat.

Fish is a temperature-changing animal, so it is particularly sensitive to the change of water temperature. For example, when the four seasons are different, there will be a saying that fishing in the beach in spring, fishing in the pond in summer, fishing in the shade in autumn and fishing in the depths in winter. Naturally, it is impossible for people to take a thermometer with them every time they go fishing to accurately measure whether the water temperature meets the requirements of fish, because there are too many factors that endanger the water temperature. Such as sunlight compressive strength, sunshine duration, soil temperature, etc. They are all uncontrollable passive factors, so we should set up a set of simple and effective methods to compare the correlation between water temperature and air temperature, so as to grasp the harm of air temperature and water temperature, water temperature and fish.

According to Mr. Xu, a fisherman in Nantong City, Jiangsu Province, "I made an appointment with my good friend to go fishing at night, and found the temperature was particularly hot at night. My good friend found it difficult to catch fish in this weather, but they were all idle and finally rushed to the river with fishing tackle. "

Just after Mr. Xu and his good friends moved their fishing tackle to the river, they found a lot of Pelteobagrus fulvidraco when they took pictures on the water with flashlights. This Pelteobagrus fulvidraco varies in size and has a large total. Its relative density has been compared with that of artificial breeding ponds. This situation also surprised Mr. Xu and his good friends. Later, Mr. Xu took this scene with his mobile phone and posted it on the short video app.
