FIELD: hydro-acoustics, possible use in fishing industry for changing behavioral characteristics of sea mammals.
SUBSTANCE: method is based on generation, amplification and emission of signals, influence of signals on sea mammals and changing their behavioral characteristics, as signals, broadband hydro-acoustic signals are utilized, emitted by selected catching tools, body of fishing ship, and also shipborne systems and mechanisms, including selecting devices of fishing ships, busy with other forms of catching, while aforementioned broadband hydro-acoustic signals are also emitted by means of spatially distributed broadband hydro-acoustic emitters, positioned on body of fishing ship, also emitted are three tonal hydro-acoustic signals in ultrasound frequencies range and tonal electromagnetic signal in ultrasound frequencies range, emitted towards wake area of fishing ship, and additionally performed is forming, below water, of curtain made of air bubbles with diameters close to resonance energy consumption frequencies of hydro-acoustic signals, emitted by selected catching tool and selecting devices of fishing ship.
EFFECT: increased efficiency of process for controlling behavior of sea mammals.
