The fish and the food reservoir to record feeding activity were kept in the central portion of a resin tank, partitioned into three parts by black cloths spread, which were used to separate the fish from the sound source. Sound stimuli applied were pure tones which generated electrically, and projected from underwater speaker set in the experimental tank. Frequencies were 200, 300, 500, 700 and 1000Hz, and projecting times were 100, 200 and 400 ms. Sound pressures ranged from 40 to 70 dB. The number of the experiments in which the fish frightened was observed by eye observation were counted. The number of the feeding activity per minute was recorded at the time, when the sound stimulus was projected. The rate of the occurrence of fish frightened increased with increasing sound pressure and the response was most sensitive at 200 Hz. The feeding activity was also disturbed at higher sound pressure and at the frequency of 200 Hz. However, the response was not so sensitive as behavior disturbance. Duration of sound projection had little effect on the behavioral disturbance so far as the present experiments are concerned.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"音刺激に対する魚類の行動変化を把握するために,マダイを用いた水槽実験を行った。1トンの FRP 水槽を黒布で3つに区切り,その中央部に実験魚と摂餌行動記録器の餌受器を入れた。これは音源に魚が触れるのを防ぎ、音源から正確な位置で魚の行動を観察する為である。音はサイン波純音を用い,周波数は200,300,500,700,1000Hz,放声時間は100,200,400ms,音圧は40-70dB の範囲で実験した。目視観察により,威嚇された魚の行動の見られた実験回数を調べ,また,放声時には同時にその直後の1分毎の摂餌行動回数を記録した。行動攪乱の起こる割合は,音圧が増加するほど増加し,周波数では 200Hz時に最も鋭敏に反応した。摂餌行動も高い音圧や200Hzで抑制的影響を受けたが,威嚇される行動ほど鋭敏な反応は見られなかった。放声時間は今回の実験範囲では行動変化に影響を与える要因とはならなかった。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"南西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Nansei
