Efficiency of a fish lift for returning Atlantic salmon at a large-scale hydroelectric complex in France
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 forty sev...
