Due to the high water temperature in summer, do fish also inhabit and feed at suitable water temperature?

Many people complain that it is very hot in summer and it is difficult to fish. In fact, this is objective. You know, fish has a suitable temperature, which is about 10~25 degrees. In summer, the temperature is generally high, often above 36 degrees, which has seriously exceeded the suitable temperature for fish, resulting in shorter feeding time for fish and more difficulty in fishing.

Fishing in hot summer and rainy days must choose a good fishing opportunity. Not all weather can make fish open their mouths. In hot weather, fish are very hot in water, so they usually rush to the surface to breathe some air in rainy days. Generally, rainy weather with long rainy duration is very suitable for fishing, because at this time, the fish mouth is good and the feeding time is long, so the chances of catching it are higher. That kind of rainstorm weather is not suitable for fishing. After the thunderstorm, the temperature dropped and the air pressure recovered greatly. At this time, the situation of fish is better. After the shower, the sun shines and there are not many fish mouths, so it is difficult to fish. When there is a typhoon in summer, it is a good time to fish after the typhoon and it is very likely to be blown out.

The sky is in a depression. O2 in water is poor due to the depression of the sky, and fish float due to lack of oxygen. Fish hardly open their mouths. If you float again, even if the fish sees your bait, it won't inhale. The reason is the same as people. The weather is stuffy, low, breathless and dizzy. Even when dealing with delicious food, they have no appetite. They just want to find a cool place to rest. To fish the element of floating, it is better to change the fishing position, find some grass holes, areas with running water, and areas in downward flow, where the water is rich in oxygen.

When the temperature is very high in summer, the dissolved oxygen in the deep water area will decrease, and the fish with high demand for dissolved oxygen will float to the shallower water layer. Even if the water temperature is high, the dissolved oxygen is relatively high. Generally speaking, pelagic fish have strong regulations on dissolved oxygen and must be heat-tolerant. Silver carp and grass carp are fish that can come out for food in summer afternoon, so it is best to choose floating when fishing.

Many fishermen feel strange when they first see it in Mingshui, because there is a saying that "if you can't catch grass, you are running around", which means that when you choose fishing spots, you must choose the part with water plants. I think this kind of scenery is more common in spring, autumn and winter, but not so good in summer.

Due to the high temperature weather in summer, there are two key factors that endanger fish's foraging: first, the water temperature is too high, and the fish feel uncomfortable and don't want to eat bait; The second is dissolved oxygen in water, which is easy to lack oxygen because of the high water temperature. Once the fish get bored, they will stop looking for food and even die. Where there are aquatic plants in summer, it is better to have fewer aquatic plants. If the water plants are lush, they will cause air circulation, and the water temperature will rise rapidly when the sun keeps shooting. In addition, lush aquatic plants will block the sun, resulting in lower aquatic plants can not carry out photosynthesis. On the contrary, it will consume O2 due to photosynthesis, and rotten animals and plants will also consume O2, resulting in underwater hypoxia. Of course, fish with high temperature and hypoxia under lush aquatic plants will not hide in such parts.
