As salmon farming scales globally, welfare science is providing actionable improvements for millions of fish.
Farmed salmon experience a range of welfare challenges including parasitism, crowding, handling stress, and inhumane slaughter. Research has shown that salmon display pain responses, learn from aversive experiences, and have complex social needs. Welfare improvements — including lower stocking densities, sea lice management, and humane slaughter — are technically feasible and increasingly demanded by retailers and certifiers.
