The increase in water

The increase in water has a great influence on the swimming and feeding of fish. The nature of fish determines that fish are extremely sensitive to changes in water level. When the water level rises, it causes the loss of some of the original food in the water body, causing panic among fishes. They swim to the shore for food, for fear of being hungry, but at the same time, because the rising water causes new water to be injected into the water body, the dissolved oxygen in the water increases. The fish became more and more active.

When the water level drops, the fish have a sense of "fear of stranding" and swim back to the deep water. The faster you fall, the faster you swim, for fear that if you run too slowly, you will be "shallowly dwelled", and you will be able to look for food wherever you are. The bigger the fish, the stronger the hunch and the quicker the escape. There are some small fishes, who are not deeply involved in the world, lack experience, and eat while swimming. Therefore, when falling into the water, especially when the falling speed is fast, you can catch some small fish, and the big fish seldom bite.

The speed of water velocity is also closely related to the activities of fish. In rivers, lakes and large reservoirs, fish generally move in waters with a velocity (0.5 ~ 1) m/s. If the velocity is too high or too small, the fish Don't want to stay. In rivers, if the flow rate is high, fish usually swim for food in tributaries or river bends; when the flow rate is low, they move in the middle and lower reaches of the main stream.
