Abstract: Reasonable setting of fishway entrance is the key to design and construction of fishway. Different environmental conditions affect swimming behaviors of fish. Reasonable utilization of environmental factors (flow, sound, light and bubble curtains) plays an important role in improvingthe efficiency of fish attraction in fishway. This review focused on the techniques of flow, sound, light and bubble curtains, summarized the main factors affecting the techniques of fish attracting and the related research results of fish behaviors. The previous studies on fish attraction mainly focus on the theoretical basis, but have been seldom applied in practical engineering. Therefore, there is an urgent need to reinforce the field application of various techniques of fish attracting and establish comprehensive techniques of fish collecting and attracting, including flow, sound, light, and bubble curtains. These efforts will facilitate improving the efficiency of fish collecting and attracting on fishway entrance.

Key words: fishway entrance, fish attraction, flow, sound, light, bubble curtain.
