Tilapia is one of the most widely farmed fish globally, particularly in Africa and Asia. Its hardiness masks significant welfare challenges in intensive production systems.
Tilapia welfare is largely invisible in the fish welfare discourse, dominated by Atlantic salmon and high-value species. But tilapia are farmed in enormous numbers, often in conditions that would not meet basic welfare standards if applied to terrestrial livestock. The very hardiness that makes them commercially attractive — their ability to survive in low-oxygen, crowded water — means their suffering in poor conditions is less economically obvious than in more sensitive species. Welfare standards for tilapia production, including stocking density limits, water quality requirements, and humane slaughter, are needed and currently almost entirely absent from major certification schemes.
