[0002] Traditional pond farming has low yields and consumes a lot of human resources. In order to increase production, the ponds are overloaded, and a large amount of water is changed, causing water pollution near the farms. The aquatic products raised in the ponds are in a sub-healthy environment for a long time, resulting in low product quality. At present, factory farms have gradually developed. By finely controlling the breeding environment and providing the best conditions for the breeding varieties, they can greatly increase the yield per unit area and solve most environmental pollution problems. However, due to the excessive cost of equipment and facilities, the unit product cost is high, and large-scale promotion is unrealistic.

The aquaculture box can keep the water in the aquaculture box and the pond water in the exchange state through its unique structure. The main body of the aquaculture box, except for the fish box mesh, is made of soft waterproof material, which is light and durable, and easy to transport and install.

[0004] However, the freshwater aquaculture tank uses an ordinary aeration and oxygenation device. As the gas drives the water to circulate in the tank, the increased oxygen floats to the surface and stays at the bottom of the aquaculture water for a very short time, making it difficult to meet the oxygen needs of fish living at the bottom of the aquaculture water. Summary of the invention

[0005] The purpose of the utility model is to solve the deficiencies of the above-mentioned technology and provide an aeration and oxygenation device for a freshwater aquaculture box.

[0007] Preferably, the aeration main pipe is provided with a plurality of first aeration holes, and the plurality of first aeration holes are arranged at intervals from top to bottom.

[0008] Preferably, the orientations of two adjacent first aeration holes are opposite.

[0009] Preferably, the annular aeration tube is a double-tube nested structure, wherein the inner tube is provided with a plurality of second aeration holes, which are arranged at intervals; and the outer tube is provided with a plurality of third aeration holes, which are arranged at intervals.
