As the temperature gets hotter, are there more and more fish species that can be caught?

Fish is an animal that likes temperature and oxygen, and the change of temperature has a great influence on the life activities of fish. Fishing in summer, the quality of fish mouth mainly depends on the change of temperature. Fishing friends are fishing on the surface, but in fact they are fighting the temperature.

Summer temperature change Let's take the temperature change of a certain area in summer as an example. The lowest temperature appears at 4~6 am, around 20℃. The highest temperature appears in 14~ 16 pm, which is about 35℃. At 8 o'clock in the morning, the temperature rose rapidly; At 20 o'clock in the evening, the temperature gradually dropped rapidly. Changes of water temperature in summer. When fishing in summer, the water temperature in fishing grounds does not change with the temperature, and the change of water temperature usually lags behind the temperature. For example, the temperature of 10 am is 28℃ and the water temperature is about 23℃; In the afternoon 14, the temperature is 35℃ and the water temperature is about 30℃. At 20 o'clock in the evening, the temperature is around 30℃, and the water temperature is around 32℃, which is slightly higher than the temperature. The water temperature mentioned here refers to the top water temperature and water meter temperature.

The wharf is located in a relatively open sea area, which is a strategic place for fishing experts and a rare area where fish can be caught all year round. When the temperature rises, you can fish under the road or on the shady side of the dock, or fish on the sunny side of the dock until the temperature drops slowly. Because the pier is an obstacle in the river, the fish can rest temporarily. Secondly, the wharf is the intersection of deep water and shallow water, which can be said to be a natural paradise for fish.

We often say that the living waters have inlets and outlets, and downward flow will continue to flow under the action of long-term wind speed. With the flowing water, the water temperature in these parts will not only be lower, but also a lot of food and sand will be washed out, which can be used for fish to find food and hide, which is very suitable for fish to survive and make them feel more belonging.

With the increase of temperature, the fish in the water gradually became active, their food intake increased greatly, and their range of activities became much larger. There is no food here, and they will immediately change to the next target. Therefore, if we still follow the idea of nesting in winter, using thick fishy nesting materials or building too few nests will attract small miscellaneous fish, even if the big crucian carp comes, it will not be able to grab the ingredients. Therefore, after the weather gets hot, the idea of digging holes needs to be changed. Just finished the nest, don't worry that the big plate crucian carp can't eat the hooks in the nest.

At this time, the air is fresh, the upper and lower water layers are convective, the dissolved oxygen is increased, and there are many components, which makes Pisces very active and is a good time for fishing in summer. If it is accompanied by a breeze of 2-3, the effect will be better.
