Tilapia is the fourth most farmed fish globally and a staple protein in developing countries. Improving welfare standards for this widely consumed species has significant potential impact.
Farmed tilapia welfare sits in a paradox: these fish are hardy enough to survive conditions that would kill more sensitive species, but their hardiness has been used to justify neglecting welfare standards rather than investing in genuinely good conditions. Tilapia that tolerate high ammonia, low oxygen, and extreme crowding are not thriving — they are coping. The welfare case for tilapia is not that they need the same standards as salmon but that they deserve standards appropriate to their biology and confirmed through welfare science rather than assumed from production survival. As one of the most widely consumed fish in the world, particularly in food-insecure regions, improving tilapia welfare has enormous potential scale.
