The Aquaculture Stewardship Council (ASC) is the world’s leading certification scheme for farmed seafood – known as aquaculture – and the ASC label only appears on food from farms that have been independently assessed and certified as being environmentally and socially responsible.

Aquaculture produces over half of the seafood eaten around the world and will be vital in providing healthy, affordable protein to the world’s rapidly growing population in the future. But like all food production, it has impacts and must be done responsibly.

ASC develops and manages the strictest standards in the industry. These standards include hundreds of requirements covering the potential impacts of aquaculture – including water quality, responsible sourcing of feed, disease prevention, animal welfare, the fair treatment and pay of workers and maintaining positive relationships with neighbouring communities.



To become ASC certified, a farm is assessed by an independent organisation against every single requirement in the relevant standard. If it passes the audit, seafood from the farm can be sold with the ASC logo, which allows consumers to reward these responsible farmers by purchasing their products.

We work with partners across the industry, environmental and scientific community and beyond – all our standards and programme updates are developed with help from NGOs, academics, farmers, retailers, and other experts, and are subject to public consultation. As part of our mission to drive up standards across the industry and beyond, we also work on standalone projects focusing on specific issues, including improver programmes for small producers and research projects.
