Sustainability has become a decisive factor for competitiveness in the bivalve sector. Consumers and international markets increasingly demand products with responsible origins, low environmental impact and proven traceability. To meet these expectations, aquaculture companies turn to environmental certifications that assess practices, performance and social responsibility. In this article, we explore the most relevant certifications and how they are shaping the future of bivalve production.
Bivalves are considered among the most sustainable foods on the planet.
Scientific studies show that well-managed farming areas function as “marine gardens”, promoting biodiversity and ecosystem health.
The most globally recognised certification. It assesses:
Focused on marine sustainability and energy efficiency. Suitable for operations with particularly rigorous environmental practices.
