Tilapia is the second most farmed fish globally, with production concentrated in Asia, Africa, and Latin America. Welfare standards in tilapia farming are poorly developed but increasingly important.
Tilapia welfare receives minimal attention relative to the scale of production. As with other farmed fish, the primary welfare problems are crowding, poor water quality, and inhumane slaughter. Tilapia are often perceived as more stress-tolerant than salmonids — this perception, while partially accurate, has been used to justify welfare conditions that would be considered unacceptable for other farmed species. The scale of tilapia production means that even modest per-fish welfare improvements would affect billions of animals annually. Developing and implementing tilapia welfare standards — including minimum stocking densities, water quality requirements, and effective pre-slaughter stunning — is an urgent priority as the sector grows.
