Wild Salmon Population Welfare | Animal Welfare Hub

Wild Atlantic salmon populations face welfare challenges across their life cycle including upstream migration barriers, sea lice from farms, and climate-driven temperature stress.

Key Facts

Atlantic salmon return from the ocean to spawn in their native rivers
Upstream migration is energetically demanding and takes weeks to months
Cumulative stressors including barriers, warm water, and lice multiply mortality risk
Post-spawning mortality is natural in Pacific salmon but not Atlantic species under normal conditions
Population recovery requires addressing both marine and freshwater life stage challenges

Welfare Considerations

Wild Atlantic salmon welfare operates across an entire life cycle that spans freshwater and marine environments, with welfare challenges at every stage. The upstream migration involves extraordinary physiological demands — fasting for weeks while navigating barriers, avoiding predators, and fighting river flows. Additional stressors from human activity — thermal barriers from warm water, physical barriers from dams and weirs, sea lice from farms — compound natural stresses and reduce the probability of successful spawning. Each individual salmon that fails to reach its spawning ground after surviving the marine phase faces an undignified end to a remarkable life journey. Population-level recovery depends on addressing welfare challenges at multiple life stages simultaneously.

What You Can Do

Support barrier removal on salmon rivers in your catchment
Advocate for sea lice management regulations near wild salmon rivers
Participate in salmon counting and monitoring volunteer programmes
Reduce river water abstraction advocacy in salmon catchment management discussions
