Both wild-caught and farmed salmon have welfare implications. A balanced analysis of both helps consumers and policymakers make more informed choices.
The wild vs farmed salmon debate is often framed in conservation terms but has important welfare dimensions. Wild salmon endure capture stress and injury in nets or fish traps; the death process in commercial wild capture is poorly controlled and often prolonged. Farmed salmon experience different welfare problems: chronic stress from crowding, parasitism, repeated treatments, and disease. Neither system is clearly welfare-superior across all dimensions. The welfare-positive consumer choice depends on the specific farm or fishery — a well-managed, lower-density farm may provide better welfare than a destructive wild fishery, or vice versa. Certification schemes attempt to identify better practice in both sectors.
