Wild salmon populations are under significant pressure from multiple threats. The welfare implications of salmon population decline and the stresses wild salmon experience connect conservation and welfare objectives.
Wild salmon welfare connects to conservation concerns through the stresses that declining populations experience in degraded environments. Salmon navigating rivers with multiple dam obstacles, running gauntlet past aquaculture facilities with elevated sea lice loads, and spawning in increasingly warm and low-oxygen conditions experience physiological stress that constitutes real welfare impact. Conservation interventions - dam removal, aquaculture siting regulations, habitat restoration, and climate mitigation - are simultaneously welfare interventions. The welfare perspective strengthens the moral case for salmon conservation beyond the ecological and economic arguments that typically dominate policy discussions.
