Salmon and Trout River Recovery: Welfare and Conservation

Wild Atlantic salmon and sea trout face severe population declines in UK rivers, with welfare implications for the fish themselves and the predators that depend on them.

Key Facts

Atlantic salmon are classified as Endangered in the UK
Rivers across England and Wales have lost salmon runs that were historically abundant
Causes include barriers to migration, habitat degradation, agricultural runoff, and climate change
Fish passes around weirs and dams allow migration but vary in effectiveness
Sea trout populations have also declined significantly in many river systems
Salmon are anadromous - they migrate from freshwater to sea and back to spawn
A salmon's journey upstream to spawn involves enormous physiological stress

Welfare Considerations

Wild salmon and sea trout welfare is shaped by the conditions they encounter on their migrations. Barriers that prevent upstream migration strand fish below weirs in unsuitable conditions. Poor water quality causes gill damage and disease. Warming rivers reduce oxygen availability and cause heat stress. Salmon die after spawning, but the quality of their migration and spawning conditions determines whether that death follows successful reproduction - an evolutionary imperative. River restoration is simultaneously a conservation and welfare imperative for these remarkable fish.

What You Can Do

Support the Atlantic Salmon Trust and Wild Trout Trust's conservation work
Advocate for fish passage on all river barriers in your catchment
Reduce agricultural runoff through supporting agri-environment schemes
Report pollution incidents to the Environment Agency immediately
Plant native trees along riverbanks through volunteering with river restoration groups
