The sound stimuli applied were pure tones which were generated electrically and projected from an underwater speaker placed in an FRP experimental tank. Frequencies used were 200, 300, 400, 500 and 700 Hz. Projecting duration was 100 ms and sound amplitude ranged from 40 to 90 dB. Pre-larvae did not respond to the audio-stimuli even at the maximum amplitude by our apparatus. After metamorphosis from pre-laval to larval stage, however, the startle response appeared and was found to depend on the amplitude of the stimulus. Thethreshold was between 55 and 60 dB at the examined frequencies. Although the response  was remarkable at the larval stage, this gradually became less marked in larger fish above 18 cm in body length. These behavioral changes to audio-stimulation may indicate a change in adaptability in order to avoid predation. No distinct effect of frequency of sound stimulus to the startle response was observed in the present experiments.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"マダイの発育段階毎の音刺激に対する驚愕行動を調べた。用いた音刺激は電気的に発生させ,これを水中スピーカーによって放声し,定位置におけるマダイの驚愕行動を観察した。音刺激は周波数200,300,400,500,700 Hz,放声時間は100msの純音で,音圧は40から90dB の間で変化させた。前期仔魚期には最高音圧でも全く反応がみられなかったが,稚魚期に入ると一斉に反応を起し,反応を起こす最低音圧は55から60 dBの範囲にあった。稚魚期から若魚期にかけて,この反応は個体差は大きくなるものの明瞭であるが,体長18cm以降では見かけ上,反応が起りにくくなる。これは生態に合せた反応の在り方の変化と考えられた。本実験範囲では周波数の反応惹起に対する効果は明らかではなかった。","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
