Tilapia are the most farmed fish species globally by volume. Despite this scale, their welfare in aquaculture has received minimal scientific and public attention compared to salmon and trout.
Tilapia welfare represents the largest welfare data gap in commercial aquaculture: a species farmed in greater volumes than any other fish in most categories receives almost no welfare research attention. The extrapolation of welfare recommendations from salmon and trout research to tilapia is problematic because tilapia are tropical cichlids with very different physiological characteristics, behavioral repertoires, and stress responses than salmonids. Without species-specific welfare research, tilapia farmers lack the evidence base to make welfare-informed management decisions, and certification bodies cannot develop meaningful tilapia-specific welfare standards. The welfare opportunity from developing basic tilapia welfare science is enormous given the production volumes involved.
