FIELD: fish farming.
SUBSTANCE: method is characterized by the formation, amplification and emission of acoustic signals under water towards a fish cluster. During feeding of farmed fish, previously recorded signals are emitted that are generated by farmed fish during their feeding. After feeding, previously recorded signals are emitted that are formed by farmed fish during their smooth movement after feeding. Broadband signals of a “white noise” type and high-gradient signals in the ultrasonic frequency range are emitted towards the fish cluster continuously, and additionally, in the opposite direction from farmed fish.
EFFECT: invention provides a rapid increase in the biomass of fish framed in cage complexes.
