FIELD: fish industry. SUBSTANCE: method consists in radiating an amplitude-modulated signal into the sea medium. In this case, the carrier and modulation frequencies are selected to obtain adequate behavior of the animals. To realize the given method, use is made of a device having modulator, generator, transmission switch, acoustic system, and control unit. The device provides for simulation of an acoustic signal of predators of the given type. EFFECT: enhanced protection of the sea animals. 2 cl, 2 dwg
