Wild Pacific Salmon Welfare and Habitat

Wild Pacific salmon face severe population declines due to habitat degradation, climate change, and overfishing, with profound consequences for entire ecosystems.

Key Facts

Pacific salmon species include chinook, coho, sockeye, pink, chum, and steelhead
Some chinook salmon populations have declined by over 90% from historical levels
Salmon are keystone species whose carcasses fertilise entire forest and river ecosystems
Water temperatures above 21 degrees Celsius cause physiological stress and mortality in salmon
Dams block salmon migration routes and are a primary driver of population collapse

Welfare Considerations

Wild Pacific salmon experience significant welfare challenges throughout their lifecycle, from predator avoidance and migration barriers to disease, parasites, and thermal stress. Climate change is intensifying these pressures, with warming rivers causing acute thermal stress during summer migration. Fish welfare science increasingly recognises that wild populations experience individual suffering at scale, not just population-level harm. Dam removal, riparian restoration, and reduced ocean bycatch all contribute to improving welfare outcomes for individual salmon.

What You Can Do

Support dam removal campaigns on salmon rivers to restore migration routes
Reduce consumption of farmed salmon, which can spread sea lice to wild populations
Choose seafood certified by schemes that consider wild salmon population health
Advocate for riparian habitat restoration along salmon rivers to reduce water temperatures
Support funding for Pacific salmon recovery programmes through environmental charities
