Wild Salmon and Sea Run Migration Welfare

Wild Atlantic and Pacific salmon undertake one of nature's most demanding migrations — and the degradation of migration routes, spawning habitat, and ocean conditions impairs their ability to complete this journey.

Key Facts

Atlantic salmon populations in many rivers have declined by over 90% since the 1970s
Dam passage, water temperature, and pollution all affect migration success
Pacific salmon returning to rivers depleted by agricultural water withdrawal face lethal warm water
Wild salmon runs provide critical nutrients to entire forest ecosystems through their carcasses
Hatchery supplementation can support populations but does not replace functional wild runs

Welfare Considerations

Salmon that cannot complete their migration face physiological and behavioral crisis — the drive to spawn is among the most powerful behavioral imperatives in vertebrate biology. Fish attempting to migrate through lethal warm water, blocked by dams, or failing to locate spawning habitat after river channelization experience the failure of a biological imperative they cannot override. The welfare dimension of salmon population decline is not just statistical but experienced by each individual fish trapped in inadequate habitat, unable to complete the journey to which their entire physiology is oriented.

What You Can Do

Support dam removal and fish passage installation on rivers with historic salmon runs
Advocate for agricultural water use policies that maintain minimum in-stream flows
Donate to Atlantic Salmon Federation and Pacific salmon restoration organizations
Choose certified sustainable wild-caught salmon from populations with strong conservation oversight
Engage with watershed restoration projects that restore spawning and rearing habitat
