Sea Bream Aquaculture Welfare | Animal Welfare Hub

Sea bream is one of the most important farmed fish species in Mediterranean aquaculture. Growing evidence suggests fish experience pain and stress, making welfare standards essential.

Key Facts

Gilthead sea bream is farmed extensively in Turkey, Greece, Spain, and other Mediterranean countries
Annual production exceeds 200,000 tonnes, supporting significant regional economies
Sea bream can live over 10 years in the wild but are typically slaughtered at 1-3 years
Fish farming density significantly affects welfare, with higher density linked to increased cortisol
Research demonstrates nociception and stress responses in sea bream similar to other vertebrates
Sea bream are susceptible to parasites like sea lice that cause chronic welfare problems

Welfare Considerations

Farmed sea bream welfare is affected by stocking density, water quality, disease management, and slaughter methods. High densities cause chronic stress and increase aggression and injury. Disease outbreaks, particularly from parasites, cause significant suffering. Humane slaughter is rarely practiced in Mediterranean aquaculture, with many fish killed by asphyxiation or CO2 stunning that may not be effective. Welfare improvements focus on reducing density, improving disease prevention, implementing stunning before slaughter, and developing early welfare indicators.

What You Can Do

Choose sea bream products certified to welfare standards where available
Support retailers that source from farms with humane slaughter commitments
Advocate for mandatory stunning requirements before slaughter of farmed fish
Reduce consumption of farmed sea bream until higher welfare standards are widespread
