Efficiency of a fish lift for returning Atlantic salmon at a large‐scale hydroelectric complex in France
Abstract This study describes the behaviour of radio‐tagged returning Atlantic salmon, Salmo salar L., at the Golfech‐Malause hydroelectric complex on the River Garonne, France. The particularity of this complex is that it is fitted with a fish lift, a type of fishway rarely tested for salmon. Only...
