关于超声波诱捕大黄鱼的可行性分析

Feasibility Analysis of Trapping Pseudosciaena Crocea with Ultrasonic Wave

采用被动声学监测的方法,取得不同状态大黄鱼的生物噪声频谱,继而根据听性脑干反应证明大黄鱼发声频率与听觉范围近似,然后以实验行为学手段测试不同音频的诱集效果。结果表明,大黄鱼产生的生物噪声区别于背景噪声,可以推测其生存状态,达到诱集实验理想的效果,并为实验提供数据支持,且相协调的发声频率与听觉敏感频率可以方便地测试适宜的声压级强度。本试验结果证实了大黄鱼摄食噪声对诱集有较大意义,可以高效、无害的应用于捕捞、监管等领域,在保护听力敏感的渔业资源和形成合理布局的驯化型海洋牧场等方面有参考意义。

The biological noise spectrum of Pseudosciaena crocea in different states was obtained by passive acoustic monitoring in this paper,and then it was proved that the vocal frequency of Pseudosciaena crocea was similar to the auditory range according to the auditory brainstem response,and then the trapping effect of different audio was tested by experimental behavioral means.The experimental results showed that the biological noise produced by Pseudosciaena crocea was different from the background noise.It can be speculated its survival state,achieved the ideal effect of trapping experiment,and provided data support for the experiment.Moreover,the coordinated sound frequency and auditory sensitive frequency can easily test the appropriate sound pressure level intensity.It was confirmed that the feeding noise of Pseudosciaena crocea was of great significance to trapping,and can be effectively and harmlessly applied to fishing,supervision and other fields,has reference significance in protecting hearing sensitive fishery resources and forming a reasonable layout of domesticated marine pasture.
