Resolving the controversy about hydropower is only possible based on reliable data on its
ecological effects, particularly fish welfare. 2. Herein, we propose a comprehensive …

Efforts to increase the share of renewable energies and to reduce the negative ecological
impacts of hydropower use are driving the development of novel hydropower technologies …

Mitigating the adverse ecological impacts on stream ecosystems caused by hydropower
expansion is a major challenge. To prevent fish from turbine entrainment and to reduce …

Current hydro power turbine technology is reviewed regarding safe fish passage. Much of
the literature has focused on dam turbine configurations, while some have recommended to …

Fishes in European rivers are threatened by manifold stressors such as structural
degradation, water pollution, overexploitation, land-use changes in the catchment, invasive …

Fish passing downstream through hydraulic structures and turbines may be exposed to an
elevated risk of injury and mortality. The majority of live fish studies are single-species …

Abstract The Archimedes Screw Turbine (AST) is an innovative type of hydroelectric power
plant that can be particularly useful in locations with very low-head sites (less than 10 m …
