| 摘 要： | 声学屏障是一种阻拦鱼类进入危险区域进而保护鱼类资源的重要手段，为筛选鱼类敏感的负趋音作为声学屏障，本研究采用6种单频音 (500~3 000 Hz)和1种宽频音 (扬子鳄吼叫声)作为实验用音对草鱼幼鱼进行负趋音的筛选研究，通过在水槽两端交替播音来对比草鱼幼鱼对不同声音的行为反应。结果显示，大多数实验鱼对声音有反应，扬子鳄吼叫声与其他声音组的差异显著。单频音实验组中播放500 Hz单频音时平均反应次数最大，为 (1.7±0.6)次，而播放扬子鳄吼叫声时平均反应次数高达 (5.0±0.9)次，显著高于其他实验音。在总平均速度中，宽频音组中草鱼的总平均速度显著高于其他组，表明草鱼对扬子鳄吼叫声敏感，产生逃窜行为。研究表明，草鱼对扬子鳄吼叫声具有负趋音性，扬子鳄吼叫声是一种对草鱼具有驱赶、威慑作用的声音。本研究可为过鱼设施中辅助诱驱鱼手段及水利结构中避免鱼类的夹带提供参考依据。

| Abstract: | The construction of dams will hinder the migration of migratory fish, and the water diversion structure and pumping activities will cause damage and death of juvenile or adult fish. In order to solve this problem, measures such as deploying physical barriers can be taken to prevent fish from entering dangerous areas. However, such physical barriers are expensive and difficult to install and maintain. Therefore, as a non-structural measure that does not cause harm to fish, acoustic deterrents are widely used in water conservancy projects. The acoustic deterrent is an important means to prevent fish from entering dangerous areas and protect fish resources. In order to screen sounds as potential acoustic deterrents, this research used six single-frequency sounds (500-3 000 Hz) and a broadband sound (Alligator sinensis roar) as experimental sounds to screen deterrents against Ctenopharyngodon idella juveniles. The behavioral responses of C. idella juveniles to different sounds were compared by alternately broadcasting at both ends of the flume. The results showed that most of the experimental fish responded to the sound, and the roar of the A. sinensis had significantly different effects from other sound groups. In the single-frequency sound experimental group, the average number of responses was the largest when playing 500 Hz single-frequency sound, which was (1.7±0.6) times, while the average number of responses was as high as (5.0±0.9) times when playing the roar of A. sinensis, which was significantly higher than other experimental sounds. In the total average speed, the total average speed of C. idella in the broadband sound group was significantly higher than that in other groups, indicating that C. idella was sensitive to the roar of A. sinensis and escaped. Studies have shown that C. idella shows negative phonotaxis to the roar of the A. sinensis, and the roar of the A. sinensis is a sound that has a driving and deterrent effect on C. idella. This research can provide a reference for the auxiliary means of inducing fish in fish passing facilities and avoiding fish entrainment in water conservancy structures. |
