Acknowledgements
We would like to acknowledge the support of the LIFE Project ”LIFE+10
NAT/AT/016 - Danube Network” and VERBUND Hydro Power GmbH, which enabled
the development and implementation of the near-natural fish bypass
system at the Ottensheim-Wilhering Hydro Power Plant. We also extend our
thanks to all persons involved in fieldwork (Umweltgutachten Petz),
particularly those responsible for fishing, tagging, and monitoring fish
migrations. Their commitment was essential to the success of this study.
