The fishing net 11 is arranged between the second chamber and the cage frame, and the coverage area of the fishing net is up to the upper floating pipe 12 and down to the lower floating pipe 13. The upper part of the second chamber is provided with a separate upper chamber 17 for accommodating the automatic feeding apparatus and the control apparatus, and the lower part is provided with a ballast water tank 4.
In this embodiment, the top of the cage 1 is provided with a bridge crane comprising a first inner rail 51, a second inner rail 52, an outer rail 53, a first bridge crane beam 54, a second bridge crane beam 55 and a self-propelled crane 56.
