The seawater aquaculture device is suspended below the support device by a steel wire rope 8. The plurality of point-absorbing wave energy power generation devices are evenly distributed along the circumference on the support device, used to capture more deep-sea wave current energy to convert it into electric energy, provide reliable energy reserves for the system, and at the same time absorb wave energy for the seawater aquaculture device, greatly resist the sea wind and waves, reduce the movement load of the seawater aquaculture device, and reduce the volume loss rate of the aquaculture cage. The seawater aquaculture device is electrically connected to the offshore wind turbine and the point-absorbing wave energy power generation device respectively, and uses the energy provided by the offshore wind turbine and the point-absorbing wave energy power generation device to maintain daily automated aquaculture work.

[0022] The seawater aquaculture device includes a gravity aquaculture cage 301 and an automatic feeding system. The top of the gravity aquaculture cage 301 is connected to the support device through a steel wire rope 8. The automatic feeding system is arranged on the support device and can be arranged in the cabinet of the control system. Its feeding pipe 302 extends downward to the top of the gravity aquaculture cage 301. The automatic feeding system is electrically connected to the control system 5, and the control system 5 controls the automatic feeding system to feed bait into the gravity aquaculture cage 301 at fixed points and in fixed quantities.
[0023] An underwater camera 7 for photographing the underwater growth of aquaculture organisms is arranged inside the gravity aquaculture cage 301. The underwater camera 7 is electrically connected to the control system 5 to ensure the normal operation order of the unmanned ocean ranch.
