Salmon welfare certification is a rapidly developing field where multiple schemes with different standards compete for market recognition, with significant variation in welfare rigor between them.
Salmon welfare certification creates market incentives for producer welfare improvement but only if the standards are genuinely rigorous and verification is credible. Programs that set meaningful maximum stocking densities, require effective pre-slaughter stunning, mandate sea lice monitoring with treatment thresholds, and use unannounced auditing provide substantially better welfare assurance than those that primarily verify input compliance. Consumer ability to distinguish between certification programs with different rigor requires transparency in standard-setting and outcome reporting that currently varies widely across the sector.
