Sea Bream Aquaculture Welfare in the Mediterranean

Gilthead sea bream is a major farmed fish in the Mediterranean alongside sea bass. Improving welfare standards in this industry requires addressing key pain points in the production cycle.

Key Facts

Mediterranean sea bream production exceeds 150,000 tonnes annually, primarily in Greece, Turkey, and Spain
Sea bream are carnivorous marine fish requiring high-protein diets
They are sensitive to handling, transport, and poor water quality
Grading (sorting fish by size) causes significant stress from crowding, netting, and air exposure
Pre-slaughter crowding and live chilling without stunning causes prolonged conscious suffering
Welfare certification for Mediterranean sea bream is growing but remains a small fraction of production

Welfare Considerations

Sea bream experience welfare challenges at multiple production stages. Grading operations require repeated handling that causes scale loss, physical injury, and acute stress. High stocking densities impair swimming and increase disease pressure. Pre-slaughter crowding and asphyxiation or live chilling without prior stunning causes prolonged suffering. Percussive stunning is a practical alternative that is increasingly adopted in higher-welfare operations. Water quality management -- particularly during summer heat events -- is critical for welfare. Consumer demand for certified humane sea bream is an important driver of industry improvement.

What You Can Do

Choose sea bream from welfare-certified Mediterranean producers
Support campaigns requiring pre-slaughter stunning for all farmed fish
Advocate for stocking density limits and grading welfare standards for sea bream
