Gilthead sea bream is one of the most farmed fish in the Mediterranean, produced in cage systems along coastal areas of Greece, Spain, and Turkey. Welfare standards for this sentient species are evolving.
Sea bream welfare follows the general pattern for Mediterranean cage-farmed fish: chronic background stress from confinement and density, periodic acute stress during routine operations such as grading and net cleaning, and poorly managed pre-slaughter and slaughter practices. The welfare case for improvement rests on the same evidence base as for other sensate fish: demonstrated cortisol responses, avoidance learning, and social stress behaviour. Regulatory progress in the EU includes increasing attention to aquatic animal welfare, with the European Food Safety Authority having published comprehensive opinions on the sentience and welfare needs of farmed fish. Consumer purchasing decisions favouring certified products, and retailer commitments to welfare-inclusive sourcing policies, are the primary market levers for improvement.
