[0028] In this embodiment, the hull of the ship adopts a semi-submersible structure. According to different situations, the draft can be adjusted by controlling the amount of water in the ballast tank. The draft can be increased during aquaculture, and the draft can be reduced during hull towing, maintenance, and cage cleaning. The aquaculture cages 300 are arranged at intervals along the length of the hull, and the aquaculture cages are surrounded by side mesh panels 310 and bottom mesh panels 320. The fishing system 600 includes a fish outlet channel 610 in the hull 100, and the fish outlet channel has a horizontal section parallel to the length of the hull and an inclined section that rises upward and extends from the end of the hull. The horizontal section of the fish outlet channel 610 is located below one side of the bottom mesh panels 320 of all the aquaculture cages 300. A conveyor belt device 620 is arranged in the channel 610, and a fish outlet located above the horizontal section of the fish outlet channel is arranged on the bottom mesh plate of the breeding net cage 300, and an open mouth connected to the fish outlet is arranged on the upper part of the horizontal section of the fish outlet channel; when using the fishing system to fish, it is necessary to reduce the draft depth of the cabin body so that there is only a small amount of water or no water in the breeding net cage, and the fish is allowed to fall into the fish outlet channel by opening the fish outlet and the open mouth of the fish outlet channel, and the fish is sent out from the discharge end of the fish outlet channel by the conveyor belt device, without using the traditional fishing method, and the fish is directly transported to the fishing boat; a crane is also installed on the deck platform, and when the fishing system 600 fails and cannot be used, or when other fishing nets are needed, the crane can be used in conjunction with the fishing nets for fishing.
