Tilapia aquaculture is expanding rapidly across sub-Saharan Africa as a food security intervention, with welfare standards varying significantly between operations.
Tilapia welfare in African aquaculture faces distinct challenges compared to developed-country production. Resource constraints limit ability to manage stocking density, water quality and disease. Tilapia lake virus causes mass mortality representing acute welfare failure at scale. However, tilapia aquaculture also provides food security for millions of people, meaning welfare improvements must be practically achievable within the economic realities of small-scale farming. Appropriate, affordable welfare standards developed with smallholder farmers have more impact than standards transplanted from industrial contexts.
