Aquaculture welfare standards vary enormously between countries, and global disparities create welfare inequities that international standards and trade rules could address.
Fish farmed in countries with minimal welfare standards suffer conditions that would be illegal in regulated jurisdictions. Global aquaculture welfare improvement requires both developing domestic standards in producing countries and using trade policy to create incentives for standards adoption. International coordination through FAO and WOAH is developing welfare guidelines that can inform national standards. Consumer and retailer pressure for certified products creates market pathways for welfare improvement.
