FIELD: fish farming.
SUBSTANCE: method includes the formation, amplification and emission of following acoustic signals under water towards a fish cluster: a harmonic signal with a sharp frequency change within microseconds, a harmonic signal with a sharp level change within microseconds, a signal of a “white noise” type with a sharp spectrum change within microseconds. The emission of all signals is carried out according to the law of random numbers. The range of all emitted signals corresponds to the range of maximum acoustic sensitivity of fish displaced from underwater technical objects.
EFFECT: invention provides displacement of fish from underwater technical objects.
