FIELD: underwater acoustics, distraction of sea animals from fishing implements with fish. SUBSTANCE: information signals according to proposed method are formed , amplified and emitted. Hydroacoustic signals emitted by selected devices are utilized in their capacity. These information signals affect sea animals and change their behavioral characteristics. Information signals in this case are emitted continuously during motion of vessel and during setting of fishing implements in sea. Energy signals are formed, amplified and emitted in addition when fishing implements are hoisted aboard of fishing vessel with the help of several hydroacoustic radiators moved apart in space. Information signals during hosting of fishing implements aboard of fishing vessel are not emitted but energy signals are emitted without interruption. Information signals affecting sea animals are masked and change their behavior. Frequency range of information and energy signals is limited from beneath by upper boundary of frequency range of highest acoustic sensitivity of fish-target of fishery. EFFECT: increased efficiency of control over behavior of sea animals and prevention of their fast adaptation to emitted signals. 5 dwg
