Abstract: 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.
