How to fish in 20 degrees weather?

It is found that the water area with fish floating head is extremely low in dissolved oxygen. If there is no floating head, but there are fish, especially crucian carp, suspended under half water or half grass, it also means that the oxygen content in the water is insufficient.

Among different kinds of fish, crucian carp has the strongest tolerance to hypoxia, while other fish have the worst tolerance to oxygen, which are carp, herring, grass carp and bream. No matter what kind of fish, the bigger the fish, the greater the oxygen resistance and the newest floating head. If crucian carp floats, such waters are not suitable for fishing at all. On the other hand, where you can catch bream, there must be other fish taking the bait.

Second, look at the water situation. Oxygen is soluble in water, only on the surface where water comes into contact with air. In other words, the larger the water surface in contact with air, the more it dissolves. If the wind blows over the water, the waves will not only increase the contact surface, but also roll. If air is stirred in water, the dissolved oxygen will increase exponentially. If the water surface is covered by aquatic plants in a large area.

The contact area between water and air is very small, and the dissolved oxygen content in this water area is very small. The dissolution of oxygen in water is also related to the water temperature. The higher the water temperature, the more difficult it is to dissolve. Humus deposited on the bottom of the water consumes dissolved oxygen, produces toxic gases such as biogas, and a series of blisters appear on the water surface. If someone thinks this is a signal that the fish has entered the nest, they will be taken in.

15 to 20 degrees is very suitable for fishing;

1, summer fishing, it is best to choose the best time for fishing in early summer and midsummer.

Early summer is a good season for fishing. The highest temperature is 26℃ to 28℃, and the lowest temperature is 16℃ to 18℃. At this time, fish prefer to feed. However, at noon, the water temperature is high and the fish swim to the deep water to enjoy the cool. In the morning and evening, the climate is cool and pleasant, and fish will feed in the aquatic plant area and the shore. It is advisable to fish in the morning and evening.

2. The best fishing time in spring and autumn is morning and morning, and the best fishing time in midsummer is between 3 pm and 8 pm. It is difficult to catch crucian carp from the morning to 5 pm in midsummer, but it is a good time to fish.
