Salmo salar Threatened
Dams and pollution are hazards for the Atlantic salmon on its run to the spawning beds. However, an older and far more serious problem has been high seas fishing, which was not subject to management regulation for sustaining yields. In 1966 when reduced stocks caused concern on both sides of the Atlantic, Canada, the United States, and Spain banned high seas salmon fishing, although other countries did not join the ban until ten years later.
