Oxygenation, aeration and water temperature regulation. Through the rotation of the impeller, the water body is stirred, and the fresh air in the atmosphere is dissolved into the water to achieve the purpose of oxygenation; at the same time, the rotating impeller laminates the water from the upper layer to the lower layer, which not only delivers fresh air, but also discharges the waste gas at the bottom of the pool. When the weather is hot, the temperature difference between the upper and lower water layers is large, and stirring the water body can balance the water temperature. Restless aerators in fish ponds, after feeding fish, fertilizing, weather changes (such as stuffy weather), or when the weather is exposed to sunlight, the temperature difference between the upper and lower layers of the water is too high, which will cause fish injuries and big fish. There is a problem because fish ponds are generally not very deep.

Fish pond aerator is a kind of machinery commonly used in fishery. Its main function is to increase the oxygen content in the water, keep the fish in the water from being deprived of oxygen, grow the anaerobic bacteria in the water, prevent the deterioration of the water quality of the pond, and threaten the living environment of the fish.

Fish pond aerators are widely used in aquaculture production, but some fishery practitioners still do not understand its working principle, type and function, and there are blindness and randomness in actual operation.

The improvement of the aerator on the pond is mainly: when the fish pond is deficient in oxygen, the low-pressure aerator can be turned on, and the "floating head" of the fish and shrimp can be paid in advance. When the dissolved oxygen in the upper layer is high on a sunny day, the convection of the water can be accelerated, the dissolved oxygen in the middle and lower layers can be increased, the fish and shrimp can grow quickly, and the bait coefficient can be reduced.
