On the way to fish-friendly hydropower
22 April, 2021
Modern hydroelectric power plants do not always protect fish more effectively than conventional ones. A research team at the Technical University of Munich has systematically studied how different types of power plants affect various fish species and their habitats. They say their detailed findings can improve future planning as well as retrofitting of existing plants.
