Description

Abstract

During the last decades, the biological understanding of connectivity between fish habitats has increased. This has resulted in restoration objectives, legislation, national and international guidelines demanding to restore connectivity for fish at anthropogenic migration barriers in many countries. In response, a large number of distinct fishways have been developed which has resulted in an increased body of literature focusing on maximizing fish passage.

However, unsuitable fishways and poorly performing fishways and are still being constructed. Reasons may be an unsufficient communication of research results but also a disconnect between fishway experts and users responsible for improving connectivity such as water authorities, NGOs, consultancies and hydropower companies. This seems especially true in cases concerning connectivity at numerous local scales such as groundsills, culverts and weirs. There are millions of such small barriers and they are blocking fish movement corridors all over the world but fishway expertise usually focuses on larger projects such as dams and large hydropower stations.

To address this challenge we have developed an easy to understand guide which helps to find the best solution possible to improve connectivity for aquatic organisms in each case. Its architecture is based on a hierarchical decision tree which is easy to handle and implement. The guide fits on one page and will lead the user to the right type of solution which can then be detailed further based on specifics from the latest research and incorporate input from interested stakeholders. The guide addresses a vast array of artificial barriers and can be actualized while research is progressing. The presentation aims to describe the guide, to explain its hierarchy and to discuss it with public at the conference.
