HERI – Research Actions Database

Welcome to the HERI Research Actions Database. The database provides details of past and present research actions related to all aspects of hydropower. The database has been structured following the categorisation developed for the HYDROPOWER EUROPE research and innovation agenda, and Strategic Industry Roadmap.

The database contents have been collated from a variety of organisations working on research actions across all sectors of the hydropower industry. The information has been share freely and is available as open access. You can search the database or add details of new initiatives to the database via the buttons below.

Investigation of the migration behavior of fish using PIT tag technology

Description

PIT tags are passive transmitters used for the electronic marking of fish. When marked fish swim past an antenna installed in a water body or a fish migration aid, they are registered and identified. With this technology, the passability, detectability, and use of fish migration aids can be studied, as well as the temporal and spatial dynamics of migrations, the distribution of fish, and habitat utilization. This will enhance the assessment of the effectiveness of ecological water management measures in the future. Furthermore, these insights can be used to further develop existing restoration measures and fish migration aids. The project area handled by VERBUND extends from the Freudenau Power Plant near Vienna along the Danube to the Inn River in Bavaria. Initial investigations have shown that shipping locks are utilized significantly for migration and that fish use fish migration aids for downstream migration. Moreover, it was confirmed that several species exhibit pronounced "homing," meaning they return to the same water body for spawning each year.
