Rotary net cage

[0016] Example 1: Reference figure 1 , image 3 , Rotary cage, including a cage with a certain breeding space surrounded by a net 5 supported by a rigid bracket, wherein: the rigid bracket is connected by a hollow tube; the rigid bracket is divided into unconnected upper Bracket 1 and lower bracket 2. The multifunctional part 4 can inflate or discharge the upper support 1 and the lower support 2 as required. By changing the weight of each part of the rigid support, the entire rotary net cage can be rotated on demand, so that each surface can be controlled to rise. To the water surface, it is easy to clean, greatly increase the dissolved oxygen in the water body, and reduce the impact of fouling organisms on the environment in the cage. The multifunctional part 4 can also increase the aeration volume to make the rotary net cage part float above the water surface, which is convenient for catching.
