光驱诱鱼技术和声驱诱鱼技术研究现状与应用前景

光、声驱诱鱼技术对保证鱼类洄游顺利通过过鱼设施具有重要价值与深远意义。光、声是影响鱼类行为特征的环境因子,不同的光、声条件会使鱼类产生不同的行为特征。阐述了光、声驱诱鱼的生理学基础,探讨了影响鱼类趋光性与趋音性的因素。通过对历年以来相关项目及研究成果的分析,总结了光、声驱诱鱼技术的研究现状,提出了光、声驱诱鱼技术的应用前景,并指出今后可将光驱诱鱼技术和声驱诱鱼技术相结合进行定向导鱼,加大对鱼类与光照的照度和光色、声音的响度和频率等因素的响应关系的研究,可供从事光、声驱诱鱼研究的科研人员提供参考。

Technique of Fish Inducing and Expelling by Light and Sound: Research Status and Application Prospect

Technique of fish inducing and expelling by light and sound is of great value and far-reaching significance in ensuring the smooth migration of fishes. Light and sound have an important effect on the behavior characteristics of fish. Different light and sound conditions will make fish behave differently. The physiological basis of the technique of fish inducing and expelling by light and sound is presented, and the factors affecting the phototaxis and phonotaxis of fishes are discussed. By analysing relevant projects and researches over years, we summarize the research status and propose the application prospect in this regard, and point out that light and sound can be combined for oriented fish inducing. Moreover, research on fish’s responses to the illuminance and photochromic of light and the volume and frequency of sound should be strengthened.
