This situation is because it will increase the cost and is not conducive to fishing.

Because fish farming fluctuates with the change of season and temperature, it is necessary to reduce the water level of fish ponds to about 65438 0.8 meters in spring, so that overwintering fish can enhance their activity and restore their appetite.

In hot summer, the water level should be raised to more than 2.5 meters to stabilize the water temperature; When the weather is cool in autumn, the water level will drop below 1.8m; In winter, the water level should be raised above 2.5 meters to keep the water temperature stable. If the fish pond is dug too shallow, the water level will not rise, which will affect the Xia Dong of fish. If you dig too deep, it will increase the cost and is not conducive to fishing.
