摘　　要：利用听觉诱发电位记录技术研究了褐菖鲉(Sebasticus marmoratus)的听觉阈值。通过采用听觉生理系统记录和分析了8尾褐菖鲉对频率范围在100—1000 Hz的7种不同频率的声音刺激的诱发电位反应。结果表明,褐菖鲉的听觉阈值在整体上随着频率增加而增加,对100—300 Hz的低频声音信号敏感,最敏感频率为150 Hz,对应的听觉阈值为70 d B re 1μPa。褐菖鲉的听觉敏感区间与其发声频率具有较高的匹配性,表明其声讯交流的重要性。同时,人为低频噪声可能对其声讯交流造成影响。The thresholds for the hearing of marbled rockfish（Sebasticus marmoratus） were studied using the auditory evoked potential（AEP） technique. The AEP responses to seven different sonic stimulations, whose tone burst frequencies are between 100—1000 Hz, from eight fishes were recorded by two subcutaneous electrodes（Tucker Davis Technologies）. Our results showed that marbled rockfish were sensitive to the low frequency sounds ranging from 100 to300 Hz, and the most sensitive sound frequency is 150 Hz, corresponding to the lowest hearing threshold of 70 d B re1 μPa. The dominant frequency of the fish sound matches with their sensitive sound frequency range, which indicates that marbled rockfish are able to detect their own sounds, and the importance of acoustic communication among them.Meanwhile, low-frequency anthropogenic noise may affect their acoustic communication.
