Wild Salmon Welfare: Ocean and River Challenges

Wild Atlantic salmon populations have collapsed across most of their range. Understanding the multiple threats they face helps prioritize conservation action and individual welfare protection.

Key Facts

UK wild Atlantic salmon populations have declined by over 70% since the 1970s
Threats include overfishing, sea lice from fish farms, habitat degradation, and climate change
Salmon face gauntlets of nets, weirs, and predators during river migration
River barriers prevent access to spawning grounds for many populations
Sea lice from nearby fish farms cause welfare impacts on migrating wild salmon

Welfare Considerations

Wild salmon face welfare challenges from both natural hazards and human impacts throughout their complex life cycle. Sea lice infestation from nearby fish farms causes skin damage and weakening on migrating smolts passing through coastal waters. River barriers cause exhaustion from attempting to ascend impassable weirs. Catch-and-release angling, while conserving individual fish, causes stress and injury. Climate warming is reducing cool oxygenated river conditions that salmon require for spawning. The collapse of wild salmon populations represents one of the most significant UK wildlife welfare and conservation failures, with individual fish welfare and population conservation intimately connected.

What You Can Do

Support campaigns for mandatory sea lice controls near wild salmon migration routes
Advocate for river barrier removal or fish pass installation on salmon rivers
Support catchment management that maintains cool, oxygenated water temperatures
Use catch-and-release best practice to minimize welfare impacts if angling for salmon
Donate to wild salmon conservation organizations working on river and marine recovery
Choose only sustainably certified Atlantic salmon if purchasing salmon products
