Friend of the Sea is a project for the certification and promotion of seafood from sustainable fisheries and sustainable aquaculture.It is the only certification scheme which, with the same logo, certifies products both wild-caught and farmed as well as fish feed, fish oil and omega-3 supplements.

Friend of the Sea started as a project of the Earth Island Institute, the NGO which operates the successful International Dolphin-Safe project. Some of the main world retailers participate, such as Carrefour Italy, Coop Italia, Esselunga, Auchan, Manor and Kaufland. Some important producers also have their products certified.

Friend of the Sea is the only scheme in the world which can certify, with the same seal of approval, products both farmed and wild-caught. Friend of the Sea is currently the main sustainable seafood certification scheme in the world, having assessed more than 10 million MT of wild-catch and 500 thousand MT of farmed products.
