12. Conservation of landlocked Atlantic salmon in a regulated river : Behaviour of migratory spawners and juveniles
Abstract : Hydropower dams represent one of the major threats to river ecosystems today. The dams block migratory routes in many rivers, which is problematic for migratory fish species. Trap-and-transport may be an alternative to fish passage solutions, as a strategy to compensate for lost river connectivity. READ MORE
