Impacts of predation by Eurasian otters on Atlantic salmon in two Norwegian rivers

Abstract: 1. The return of the Eurasian otter (Lutra lutra) to western Norway has sparked human-predator conflicts because otters prey on vulnerable Atlantic salmon (Salmo salar) populations. Although predation may not be the ultimate cause of salmon population declines, otters that kill adult salmon in rivers before they spawn impact the salmon spawning stock, with potential consequences for stock recruitment and ecosystem services (especially fisheries).2. To gain insight into impacts of otter predation on salmon popu… Show more

“…This usually leads to establishing predation studies that attempt to document how large the 'predation problem' is. One such example is seen in Scandinavia, where the resurgence of Eurasian otter (Lutra lutra) populations has raised concerns among anglers over their potential impact on Atlantic salmon (Salmon salar) populations [27]. Another example is in western Canada, where there has been considerable debate over the culling of grey wolves (Canis lupus), driven by concerns about their impact on terrestrial ungulates [28].…”
