Tilapia is one of the world's most widely farmed fish. Welfare conditions in tilapia aquaculture vary enormously globally, with significant implications for fish welfare.
Tilapia farming welfare is a global-scale welfare challenge. As one of the world's most produced fish species, with billions farmed annually, even modest welfare improvements per fish would represent an enormous aggregate welfare gain. The challenges are economic and regulatory: many tilapia farms operate in low-income countries where welfare regulation is absent and profit margins are thin. Consumer awareness of tilapia welfare is low, making market-driven welfare improvement slow. Nevertheless, progress is possible: ASC certification exists for tilapia and sets minimum welfare-relevant standards. Supporting tilapia welfare improvement through purchasing choices and advocacy can drive improvement at scale.
