Abstract

Properly designed fishway plays an important role to mitigate the migrating problem of fish and help them meet their life cycle’s basic requirements, especially the spawning activities with enhancing the local ecosystem as well. However, the fishways are still constricted at the small section of the dam or weir giving less priority and the designs of fishways are further limited by engineering, hydraulic and economic constraints. Thus, this paper presents an overview of the fishway design history and their consequences following different available literatures till date. Furthermore this paper also suggests on considering some important parameters during design such as turbulence, roughness coefficient, minimum head difference, slope which have a key role in improving the working efficiency of fishway. In addition, this review provides following recommendations: i) Need to improve downstream design of fishway and associated experimental methodology, ii) Consideration of river temperature with dissolved oxygen and their effect on fish behavior during design work, iii) Importance of further research work on coarse species along with other economically important fish, and iv) Updating the fishway design by considering fluctuating water level condition in the river. Hence this paper can contribute in the enhancement and restoration of fisheries resources from the perspective of fish passage design problems and their solution. Furthermore it may help the new researchers and designers to upgrade the existing design concept for the better result in fishway efficiency in coming future.
