Pacific and Atlantic salmon populations have declined dramatically due to dams, habitat loss, and overfishing. Conservation of wild salmon serves both biodiversity and the welfare of these ecologically vital fish.
Wild salmon in degraded habitats experience chronic thermal stress, blocked migration routes, and increased disease exposure. Fish struggling to reach spawning grounds in degraded rivers experience prolonged physiological distress. Dam removal, riparian restoration, and reduced fishing pressure have produced measurable recovery in some systems. The welfare of wild salmon populations is inseparable from the ecological health of the watersheds they inhabit.
