[0029] Please refer to Figure 1 andFigure 4 The lifting and fishing assembly 10 comprises a lifting frame 19, the four corners of the lifting frame 19 are concave structures, and the lifting frame 19 is slidingly limited with the longitudinal frame 1, the ends of the adjusting ropes 9 are fixed on both sides of the upper end surface of the lifting frame 19, the inner side of the lifting frame 19 is provided with an inner boss, the inner boss is provided with a clamped fishing frame 20 on the upper side, and the inner part of the fishing frame 20 is fixedly provided with a fishing net for separating fish bodies of different sizes, a plurality of screw holes are arranged in the inner boss of the lifting frame 19, and the upper end surface of the fishing frame 20 is provided with a plurality of fastening bolts 21, and the fastening bolts 21 are connected with the inner boss of the lifting frame 19 through threads;

[0030] Before releasing the fry, the fishing frame 20 provided with the fishing net is selected according to the size of the fish to be fished. The fishing frame 20 is placed on the inner boss on the inner side of the lifting frame 19, and the inner boss plays a supporting role. Then the fastening bolts 21 are used to threadedly connect the screw holes on the upper end surface of the fishing frame 20 with the screw holes in the inner boss of the lifting frame 19, so as to realize the fastening of the two. When fishing is needed, the driving assembly works, the adjusting ropes 9 are wound, the lifting frame 19 is lifted, and the fishing frame 20 and the fishing net in it are lifted. In the lifting process, small fish can pass through the mesh of the fishing net, and fish larger than the mesh are blocked above the fishing net, which facilitates the replacement of fishing nets of different mesh sizes and meets the different fishing needs of different sizes of farmed fish. The cooperation of the inner boss and the fastening bolts 21 makes the fishing frame 20 stable and will not loosen or fall off during lifting. Through the screening effect of the fishing net, fish of a specific size can be accurately fished, avoiding overfishing of small fish.

[0031] Further, the longitudinal frame 1, the lower cross frame 2, the upper cross frame 3 and the lifting frame 19 are all made of stainless steel, which prolongs the service life of the net cage main body and the lifting and fishing assembly 10, reduces the maintenance and replacement cost of the equipment.
