METHOD OF CONTROLLING FISH BEHAVIOUR Russian patent published in 2009 - IPC A01K79/00 

FIELD: agriculture.

SUBSTANCE: present invention relates to acoustic methods of stimulating motion behaviour of fish and can be used in industrial fishery and fish-breeding for attracting and concentrating fish in the area around fishing equipment with subsequent catching or for protection purposes for keeping fish in sections of a water body, favourable for growing and spawning until the of the growing and spawning period. The method of controlling fish behaviour involves generation and emission of information hydroacoustic signals in an aqueous medium, transmission of the signals to the fish and changing their behavioural characteristics. The information signals used are hydroacoustic signals with given spectral-energy and time parameters of sounds of physostomous fish in the 20-3000 Hz frequency range with sound pressure level of up to 10 Pa/1 m, depending on the species composition of the fish on which the signals are directed. Hydroacoustic information signals with given parameters act on the behaviour of fish on an unconditional-reflex level and arouses their adequate reaction to move to the sound source.

EFFECT: efficient and prolonged control of fish behaviour.
