| 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，本文采用六种单频音（500-3 000 Hz）和一种宽频音（短吻鳄吼叫声）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。结果表明，大多数实验鱼对声音有反应，短吻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，而播放短吻鳄吼叫声时平均反应次数高达5±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，表明草鱼对短吻鳄吼叫声敏感，产生逃窜行为。本研究表明，草鱼对短吻鳄吼叫声具有负趋音性，短吻鳄吼叫声可能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: | Acoustic barrier is an important means to prevent fish from entering dangerous areas and protect fish resources. In order to screen fish-sensitive negative sounds as acoustic barriers, six single-frequency sounds (500-3 000 Hz) and one broadband sound (alligator roar) were used as experimental sounds to screen negative sounds of grass carp juveniles. The behavioral responses of grass carp juveniles to different sounds were compared by alternately broadcasting at both ends of the sink. The results showed that most experimental fish responded to sound, and the roar of alligator was significantly different 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 ± 0.9 times when playing alligator roar, which was significantly higher than other experimental sounds. In the total average speed, the total average speed of grass carp in the broadband sound group was significantly higher than that in other groups, indicating that grass carp was sensitive to the roar of alligator and escaped. This research shows that the grass carp has a negative tendency to the roar of the alligator, and the roar of the alligator may be a sound that has a driving and deterrent effect on the grass carp. This research can provide a reference for the auxiliary means of luring and driving fish in fish passage facilities and the avoidance of fish entrainment in water conservancy structures. |
