How and where to pass? Atlantic salmon smolt’s behaviour at a hydropower station offering multiple migration routes
peer reviewed We studied downstream migration behaviour of Atlantic salmon smolt at a hydropower station that offers four safe (weir, new incision gate on weir, downstream bypass, Archimedes screw) and one potentially unsafe (Kaplan turbines) migration routes. We followed hatchery smolts using radio...
