Energetic Consequences of Stranding of Juvenile Atlantic Salmon (Salmo salar L.)
An effect of hydropower and hydropeaking regulation in rivers is stranding of fish. Those fishes that survive stranding may experience stranding as a stressful situation. In four experimental stranding experiments (each with 6 individuals in 10 control and 10 treatment replicates), the energetic con...
