Description

Abstract:

According to the Council Regulation of 18 September 2007 establishing measures for recovery of the stock of European eel, the Member States must significantly improve both upstream directed migration of juvenile eels as well as protection and downstream migration of Silver Eels at hydropower plants. Since then, various measures have been implemented in some rivers and hydro installations: mechanical fish protection systems with a flow rate up to 70 m³/s combined with special bypass systems for eels. Trap and truck as well as eel friendly turbine management with early warning systems are measurements on large hydropower plants. Modified turbine runners are another possibility to save eel during their downstream migration. The contribution discusses the different methods and shows the advantages and disadvantages as well as their application.
