Aquatic animal welfare policy is advancing globally as evidence for fish and crustacean sentience grows. Understanding the policy landscape helps advocates identify where to focus attention for maximum impact.
Aquatic animal welfare policy is advancing but remains far behind terrestrial animal welfare law in most jurisdictions. The primary gap is not scientific — evidence for fish pain and welfare-relevant experiences is well-established — but political and economic. Fishing and aquaculture industries are major economic interests that resist welfare regulation, and fish are culturally distant from the charismatic mammals that typically drive welfare legislation. Advocates working on aquatic welfare policy must engage both the scientific evidence and the economic case for welfare improvement — reduced antibiotic use, improved product quality, sustainable certification premiums — to build the cross-sector coalitions needed for legislative progress. Each jurisdiction that extends welfare protection to aquatic animals provides a precedent for others to follow.
