Wave transmission control device, underwater organism guidance device, and wave transmission control method

An underwater organism guidance device comprising:

• a transmitter to form a sound field in water;
• processing circuitry
• to, when detection information is input from a sensor to detect an organism in water, perform determination of
• a characteristic of the organism among a plurality of characteristics, and
• a distribution state of a location of the organism in the water with respect to a position of the transmitter for each characteristic among the plurality of characteristics, using the detection information,
• to acquire sound information based on the characteristic using a database in which a plural pieces of information of the plurality of characteristics of organisms and a plural pieces of sound information are respectively associated with each other, and
• to determine a sound output condition in such a manner that a distribution state changes from the distribution state to a set distribution state which is set for each of the plurality of characteristics received before processing starts and to cause the transmitter to output a sound based on the sound information using the sound output condition.

A wave transmission control method to control a transmitter to form a sound field in water, the wave transmission control method comprising:

• when detection information is input from a sensor to detect an organism in water, causing processing circuitry to perform determination of
• a characteristic of the organism among a plurality of characteristics, and
• a distribution state of a location of the organism in the water with respect to a position of the transmitter for each characteristic among the plurality of characteristics, using the detection information;
• causing the processing circuitry to acquire sound information based on the characteristic using a database in which a plural pieces of information of the plurality of characteristics of organisms and a plural pieces of sound information are respectively associated with each other;
• and
• causing the processing circuitry to determine a sound output condition in such a manner that a distribution state changes from the distribution state to a set distribution state which is set for each of the plurality of characteristics received before processing starts and causing the transmitter to output a sound based on the sound information using the sound output condition.
