 note = {This paper describes some feature of the swimming sounds for fishes within the netting cages were recorded at Hayato culture ground in the innermost area of Kagoshima Bay. Subjects of investigation were Yellowtail Seriola quinqueradiata, Amberjack Seriola dumerili, Amberjack Seriola lalandi, Red Sea Bream Pagrus major, and Tiger Puffer Takifugu rubripes. The recorded underwater sounds were analyzed with the three kinds of method in order to obtain the characteristics of wave forms and frequency; three-dimensional expression of multiframe wave form, power spectrum, and one third octave band analyses. In result, swimming sounds in the main band width ranging from 50Hz to 400Hz, and TEMPURA Noise in the band width ranging above 500Hz were observed to two typical wave form of underwater sounds in a netting cage. Swimming sounds were sporadic wave in a state of pales. A concavity pattern appeared at the near boundary of them in the band width ranging from 200Hz to 1kHz., 高密度魚群の発する遊泳音の特徴を調査するため,鹿児島県姶良郡隼人町沖合に設置されている城山合産株式会社隼人養殖場海上生簀にて水中音の測定を行った。対象魚種はマダイPagrus major,ブリSeriola quinqueradiata,ヒラマサSeriola lalandi,カンパチSeriola dumerili,トラフグTakifugu rubripesであった。その結果,散発的に現われる魚種に異なるパルス状波形が観察され,周波数解析を行った結果,1) 50~400Hzの周波数成分を主とする高密度魚群内の遊泳音,2) 500Hz以上の高周波成分を主とするテンプラノイズが明らかになった。また,両波形の存在によりその境界付近約200Hz~1kHzにはパワースペクトルの凹状帯が存在した。なお,刻々変化する周期持続時間等の解析には時間軸上での解析が必要である。},
