Tilapia is one of the most widely farmed fish globally — welfare considerations in intensive tilapia aquaculture systems.
Tilapia welfare is understudied relative to the scale of tilapia production, reflecting a broader pattern in aquaculture where the volume of production is inversely related to the welfare science investment. Tilapia are tolerant fish in the sense that they survive suboptimal conditions better than salmonids, but tolerance is not the same as welfare — fish that survive high-density, low-oxygen conditions may be experiencing chronic physiological stress without showing the mortality signals that would prompt management concern. Building a welfare evidence base for tilapia and translating it into production standards requires both scientific investment and industry willingness to act on the evidence.
