Wild Atlantic Salmon River Habitat Welfare

Wild Atlantic salmon face existential threats from habitat degradation, barriers, warming rivers and sea mortality, with individual welfare implications at multiple life stages.

Key Facts

UK Atlantic salmon populations have declined by over 70% in 30 years
River temperatures above 20 degrees Celsius cause thermal stress and mortality
Migratory barriers including weirs and culverts block upstream spawning migration
Agricultural and urban run-off reduces water clarity and spawning gravel quality
Sea survival rates have declined dramatically, reflecting changes in marine food web structure

Welfare Considerations

Wild Atlantic salmon welfare spans freshwater spawning and marine feeding, requiring action across both environments. River restoration and barrier removal are the most tractable near-term interventions.

What You Can Do

Support river restoration and fish pass installation on blocked migration routes
Advocate for agricultural run-off controls that protect salmon river water quality
Report fish pass blockages and barriers to your local river trust or SEPA
