Fish welfare certification is in its earliest stages but growing rapidly. Understanding what current and emerging standards address enables consumers and retailers to make genuinely welfare-informed aquatic product choices.
Fish welfare certification faces the challenge of developing in a context where the science of fish sentience is still being established and where the welfare baseline is extremely low. The commercial fish industry has operated for decades without welfare considerations, and the first generation of welfare standards must simultaneously establish baseline requirements, build industry understanding of fish welfare, and create measurable improvement pathways. The most impactful initial standards — requiring pre-slaughter stunning, maximum stocking density limits based on welfare rather than productivity alone, and water quality standards calibrated to fish welfare rather than just survival — would deliver welfare improvements to billions of fish annually if widely adopted.
