Atlantic Salmon River Habitat Welfare UK

Wild Atlantic salmon in UK rivers face multiple stressors from warm water temperatures, pollution, barriers and sea lice from salmon farms threatening population viability.

Key Facts

Atlantic salmon populations at critically low levels in many UK rivers
Water temperature above 23 degrees Celsius causes heat stress and mortality
Migration barriers prevent salmon reaching spawning grounds
Sea lice from coastal salmon farms affect wild smolts in marine phase
Illegal poaching and legal fishing both remove fish from vulnerable populations

Welfare Considerations

Salmon holding in warm water pools during drought periods suffer physiological stress and elevated mortality. The welfare of individual fish matters alongside conservation concerns, and reducing both natural and anthropogenic stressors improves outcomes.

What You Can Do

Advocate for fish passage improvements at weirs and dams
Support river cooling through riparian tree planting initiatives
Choose responsibly sourced seafood to avoid contributing to sea lice pressure
Report illegal poaching to local police and river authority
