The present invention relates to a self-energized rising-diving adjusting device for a euphausia superba beam trawl, including rising-diving adjusting apparatuses symmetrically installed on a beam. The rising-diving adjusting apparatuses include a fairing, a protective cover, a propeller water flow generator, a bidirectional driving motor, a rotary screw, a lifting and lowering connector and a fin. The protective cover is connected with a rear end of the fairing, the propeller water flow generator is installed inside the fairing, the bidirectional driving motor is powered by the propeller water flow generator, two ends of the rotary screw are installed on the protective cover in a vertical direction in a mode of rotating bidirectionally, the rotary screw is driven by the bidirectional driving motor to rotate, the lifting and lowering connector is assembled on the rotary screw through a thread structure, a front end of the fin is horizontal and both sides of the fin are rotationally connected with the protective cover respectively, and a rear end of the fin is connected with the lifting and lowering connector and is driven to adjust an angle of the fin through lifting and lowering movement of the lifting and lowering connector. The present invention can realize controllable and self-energized active rising-diving adjustment of the beam trawl.
