[0022] The technical means adopted to achieve the predetermined invention purpose of the present application will be further described below in combination with the drawings in the embodiments of the present application.

[0023] EMBODIMENT

[0024] Referring to Figure 1 , a fishery fishing system comprises:

[0025] The cantilever crane 1 is arranged on the bank of the fishpond, the hoisting arm of which extends into the fishpond, the length of the hoisting arm is adjustable, and the end of the hoisting arm is provided with a lifting hook; the fishing device 2 is hung on the lifting hook.

[0026] Referring to Figure 2 and Figure 3 , the fishing device 2 comprises a fishing box 21, the side of the fishing box 21 is connected with a side door 22 which is opened by turning outward through a door opening mechanism 23, the top of the fishing box 21 is provided with a lifting piece 24 for hanging on the lifting hook, and the inside of the fishing box 21 is provided with a camera 25 and a bait 26.

[0027] A plurality of water holes are arranged on the upper wall, the side wall and the side door 22 of the fishing box 21, and a weighing sensor is arranged on the bottom wall of the fishing box 21.

[0028] ​In use, first, the fishing device 2 is hung on the hook, the cantilever crane 1 is controlled to work by the control unit, and the fishing box 21 is lowered to the water below the tightened purse seine. Then, the door opening mechanism 23 is driven to work by controlling the corresponding electromagnetic valve, the side door 22 is opened outward, and the fish enters the fishing box 21. At the same time, the camera 25 obtains the image information of the fish in the fishing box 21 and sends it to the control unit for analysis. When the number of fish entering the fishing box 21 reaches the preset value or above, the side door 22 is controlled to close. Then, the control unit controls the hook of the cantilever crane 1 to rise, and the fishing box 21 is lifted to the water surface. After a certain time, the water in the fishing box 21 is all overflowed, and the weight information obtained by the weighing sensor is sent to the control unit to obtain the weight of the fish in the fishing device. Finally, the cantilever crane 1 is controlled to rotate to the top of the transport vehicle, and the side door 22 is controlled to open, so that the fish in the fishing box is unloaded into the small fish boxes arranged in the transport vehicle.

[0029] Referring to Figure 2 , the camera 25 is arranged on the top wall of the fishing box 21 and is used to obtain the image information of the fish entering the fishing box and send it to the control unit. When the number of fish in the fishing box reaches the preset number, the control unit controls the cantilever crane 1 to start and lift the fishing device out of the water. The bait 26 is arranged on the bottom wall of the fishing box 21 and can be a light emitting lamp or fish food, which is used to attract fish into the fishing box 21.

[0030] In order to realize the sustainable development of fishery and prevent overfishing, the water hole is arranged according to the minimum volume of the fish to be fished, which is used for water inlet and small fish to escape.

[0031] Further, the fishing box 21 has multiple specifications according to the volume of the fish to be fished, and the water holes of the fishing box 21 of each specification correspond to the volume of the fish to be fished. In this way, fish that have not grown to a certain volume can escape from the water holes of the fishing box 21, preventing overfishing of fish that have not grown.

[0032] Referring to Figure 2 and Figure 3 , the door opening mechanism 23 includes a pneumatic telescopic rod, the upper end of the pneumatic telescopic rod is hinged to the side wall of the fishing box 21, and the lower end is hinged to the side door 22.
