Background
A fish culture technique in net cage features that the net or metal net is used as the material to form a net body with a certain shape and specification, which is used to culture fish in the water body. The net cage fish culture has the advantages of reducing the activity of fish shoal, realizing the free exchange of water bodies inside and outside the net cage and excrement, avoiding the invasion of enemy organisms and the like. Therefore, the net cage fish culture has the characteristics of high yield, low cost, small investment, convenient management and the like, and can be used for effectively developing rivers, lakes and seas. Because severe weather such as typhoons exists in the sea area environment, the strength of the traditional net cage is required to be high, and therefore, the net sea area cultivation structure in the net is created. The structure is shown in figures 1 and 2, and when typhoons come, the structure is provided with an outer net structure capable of rotating by a fixed shaft, so that the impact of typhoons is avoided. However, when the structure is used for large-scale sea area cultivation areas, high manpower and material resources are required to be consumed for feeding and capturing fish shoals, if the bait is too concentrated during feeding, the fish shoals at a single feeding point are injured due to large competition of gathering quantity for food capture, and the feeding methods such as pond fish culture and the like are difficult to utilize due to more complex sea area environments; when fishing a fish shoal, the fishing net is adopted to cause injury to specific fishes cultivated in the sea. For optimizing net-in-net mechanisms, it is necessary to make feeding and capturing of fish more convenient and to increase the survival rate of fish and save manpower.

binding and fixing narrow openings on the left side and the right side of the aquaculture outer net of the device with a rotary main shaft through ropes, starting a motor to drive the aquaculture outer net to rotate through the rotary main shaft, enabling the immersed part to face upwards after the aquaculture outer net rotates 180 degrees, and removing algae organisms at the part through solar insolation, wherein the fish catching net cage is still arranged below the sea surface; when severe typhoon weather is met, the ropes connected with the rotating main shafts at the two sides of the outer culture net are removed, the fishing net cage is placed below the sea surface, the outer culture net rotates around the rotating main shafts under the impact of typhoon, the rotating main shafts remain stationary, and the outer culture net can be prevented from directly bearing the impact of typhoon by self-rotation;
2) When the bait is thrown by the net sea area culture feeding and capturing device in the net:
the motor drives the rotary main shaft to adjust to enable the bait inlet to be arranged at an upward position, then the motor keeps static and does not output power, the booster water pump sucks seawater in a self-priming mode, the pressurized seawater is sprayed into the bait pipeline, after a period of time, the bait inlet is opened, the bulk bait made of nutrient substances is poured into the bait pipeline, advances along with water flow, and then the bait inlet is closed; the bait flows to a plurality of bait outlets arranged along with water, and seawater is sprayed out from the plurality of bait outlets along with the bait due to high pressure; the gathering outer cover wraps the bait outlet corresponding to the fishing net cage below the gathering outer cover, so that the bait flows out from the bait gathering outlet, and the fishing net cage is positioned below the sea surface at the moment, so that the bait is prevented from falling; in addition, large bait particles are left in the fishing net cage through sinking interception of the bait on the bottom of the fishing net cage, so that the problem of pollution of the large bait particles to the sea is avoided as much as possible; bait is sprayed and put from a plurality of bait outlets, the putting points are more, the dispersion effect is achieved, and the injury of fish shoals with single putting points due to large competition of gathering quantity for food is avoided;
3) When the fish shoal is caught by the net sea area culture feeding and capturing device in the net:
firstly, bait is put in, and the specific bait putting steps are as above; bait is sprayed and put from a plurality of bait outlets to gather fish shoals, a motor is started to rotate a rotary main shaft anticlockwise to enable a suspension rope to be wound, a fishing net cage rises, and the motor can be stopped after the top surface of the fishing net cage is pulled out of the sea; the fishing person gets into the net from outside the outer net of the cultivation by taking the boat, extracts the fish shoal in the fishing net cage in the net, flushes the fishing net cage clean, starts the motor, rotates the rotating main shaft clockwise, and after the fishing net cage gets into a certain distance below the sea surface, the fishing person gets away from the outer net of the cultivation by taking the boat, thus the fishing can be completed.
