UNDERWATER SOUND GENERATING SYSTEM AND MITIGATION METHOD OF INFLUENCE ON FISH BY UNDERWATER WORK SOUND
To provide an underwater sound generating system for mitigating influence on fish by an underwater work sound by keeping the fish away from an underwater work sound generation source in a water area when carrying out underwater work such as installation of piles, and a mitigation method of the influence on the fish by the underwater work sound using the underwater sound generating system.SOLUTION: The underwater sound generating system comprises: an underwater sound generating device 11 for outputting a sound to the underwater to keep fish away from a target water area; and a buoyancy body 12 for supporting the underwater sound generating device in the underwater by floating on a water surface, wherein the underwater sound generating device outputs one or more sounds to the underwater with sound pressure of at lease 140 dB by transmitting them at frequency 0.1 to 2 kHz, a transmission duration of 0.1 second to 10 minutes, and a transmission interval of 1 second to 10 minutes.SELECTED DRAWING: Figure 1
【課題】杭打設等の水中工事の実施の際にその水域において水中作業音発生源から魚類を遠ざけて水中作業音による魚類への影響を緩和する水中音発生システムおよびこの水中音発生システムを用いた、水中作業音による魚類への影響緩和方法を提供する。【解決手段】この水中音発生システムは、対象水域において魚類を忌避するために水中に音を出力する水中音発生装置１１と、水面に浮揚して水中音発生装置を水中で支持する浮力体１２と、を備え、水中音発生装置は、周波数0.1～2kHzの範囲内の１または複数の音を、発信時間0.1秒～10分、発信間隔1秒～10分で発信し、少なくとも音圧140dBで水中に出力する。【選択図】図１
