Salmon Climate Change Welfare

Warming stream temperatures from climate change stress salmon populations, causing physiological harm and altering migration timing with cascading welfare effects.

Key Facts

Atlantic and Pacific salmon require cold, well-oxygenated water for survival
Water temperatures above 68 degrees F cause thermal stress and increased disease susceptibility
Climate change is warming streams by 1-2 degrees C above historical averages
Altered migration timing disrupts access to spawning habitat

Welfare Considerations

Salmon experiencing thermal stress from warming streams face physiological challenges including immune suppression and increased disease vulnerability. The altered migration timing means some fish cannot complete their life cycle successfully. Conservation interventions including riparian shade restoration and cold water refuges provide local thermal protection while climate mitigation addresses the root cause.

What You Can Do

Support riparian restoration projects that shade streams and lower water temperatures
Advocate for ambitious climate action to protect salmon habitat
Reduce salmon consumption from populations under thermal stress
Support dam removal projects that restore cool water and spawning access
