Sea Bream Welfare in Mediterranean Cage Aquaculture

Gilthead sea bream is a cornerstone of Mediterranean aquaculture, with welfare standards increasingly required by importing markets and retailers.

Key Facts

Gilthead sea bream (Sparus aurata) production exceeds 200,000 tonnes annually in the Mediterranean
Greece, Turkey, and Spain are the leading producing countries
Crowding during harvesting and sorting is a significant acute welfare challenge
Sea lice management requires treatments that cause welfare compromise if poorly applied
Electrical stunning before slaughter is commercially viable and increasingly required by EU retailers

Welfare Considerations

Sea bream welfare in Mediterranean cage systems is affected by stocking density, crowding during harvest, and water temperature. They are sensitive to stress, showing strong cortisol responses to handling and crowding. Broodstock management, hatchery welfare, and transport of juveniles to grow-out cages each represent welfare events that can be mitigated through careful management. EU retail standards increasingly require welfare assessments from Mediterranean farms, driving standards improvement throughout the supply chain.

What You Can Do

Choose sea bream certified by welfare-audited schemes such as ASC or equivalent
Ask retailers about welfare assessment requirements for Mediterranean sea bream suppliers
Support EU aquaculture welfare regulations that include sea bream specifically
Encourage Mediterranean producing countries to adopt and enforce minimum welfare standards
