Tilapia is one of the most widely farmed fish globally, and improving welfare standards for this sentient species is an increasingly important area of aquaculture reform.
Tilapia in intensive systems experience overcrowding, water quality fluctuations, and handling stress that impair welfare. High stocking densities cause aggression, fin erosion, and chronic stress that suppress immunity and increase disease susceptibility. Harvest by crowding and live transport without stunning results in prolonged stress and suffering before death. Welfare improvements including reduced stocking densities, better water quality management, and humane slaughter practices would significantly improve outcomes.
