Aquaculture welfare certification has evolved significantly over the past decade, with new criteria, better measurement, and expanding species coverage marking genuine progress.
Aquaculture welfare certification has made genuine progress over the past decade, moving from a near-complete absence of welfare criteria to increasingly sophisticated frameworks that include outcome-based indicators, technology-assisted monitoring, and expanding species coverage. The development of operational welfare indicators — standardized, measurable welfare outcome measures that can be assessed at harvest — represents a significant advance from input-based standards. Consumer and retailer pressure has driven certification bodies to strengthen standards and expand species coverage beyond the premium salmon sector. The remaining gaps are substantial — most farmed fish species have no welfare certification options, and existing standards vary significantly in rigor. Progress requires continued advocacy from welfare organizations, retailers, and welfare-conscious consumers.
