European sea bass farming is increasingly subject to welfare certification schemes, driving improvements in stocking density, slaughter methods, and environmental conditions.
Sea bass are active, predatory fish that show clear stress responses to overcrowding, poor water quality, and rough handling. As evidence for fish sentience has grown, the aquaculture industry has faced increasing pressure to improve welfare standards. Certification schemes have been a powerful driver of change, creating market incentives for farmers to adopt higher welfare practices. However, coverage remains uneven and enforcement varies significantly by region.
