Wild Salmon Pacific Population Welfare

Pacific salmon face multiple stressors from climate change, habitat loss, and fishing pressure that affect population welfare across their entire life cycle.

Key Facts

Pacific salmon populations have declined by 50-90% in many rivers since the 1980s
Salmon require cold, clean water for successful spawning and juvenile development
Dam removal has restored salmon populations in several river systems
Salmon are keystone species supporting hundreds of other species in river ecosystems
Climate-driven warming is making many previously suitable rivers unsuitable for salmon

Welfare Considerations

Wild Pacific salmon welfare spans their entire life cycle across thousands of kilometers of ocean and river habitat. Stressors include warming river temperatures that cause heat stress during upstream migration, low river flows that concentrate fish and increase disease transmission, and the physical challenge of migration itself becoming more lethal as water temperatures rise. Population welfare decline has cascading effects on predators including bears, orcas, and eagles that depend on salmon.

What You Can Do

Support salmon habitat restoration and dam removal projects
Advocate for water temperature standards that protect salmon migration corridors
Choose salmon from fisheries with documented sustainable harvest practices
Reduce carbon emissions to help preserve cold-water salmon habitat
