[0041] The working principle of this embodiment is as follows:

[0042] During use, when the external power is turned on and the staff performs fishing operations, the staff places the fishing box 24 into the water area where fishing is to be carried out. The waterproof imitation ultrasonic simulator 17 can emit ultrasonic waves that simulate fish, causing the fish to swim from the fishing net 19 into the fishing box 24. The camera 23 monitors the inside of the fishing box 24 in real time. The staff can observe the situation inside the fishing box 24 through the display screen 26. When the number of fish inside the fishing box 24 reaches the ideal amount, the staff starts the vacuum pump 5. The vacuum pump 5 evacuates the inside of the housing 15, creating an air pressure difference between the inside of the housing 15 and the fishing box 24, so that the suction hood 18 sucks the fish and water inside the fishing box 24. The fish will be transported into the housing 15 by the water flow. After the fish inside the fishing box 24 are transported into the housing 15, the staff opens the pressure relief pipe 4 to relieve the pressure, and opens the switch of the water delivery pipe 11 to filter out the water, so that the fish are left in the rain collection tank without having to lift the fishing box 24 out of the water, improving the fishing efficiency. Moreover, the air pressure detection sensor 7 can detect the air pressure inside the housing 15 in real time, and the staff can control the fish suction speed according to the magnitude of the air pressure inside the housing 15.
