The Marine Conservation Society (MCS)good fish guide is a British nonprofit that is helping consumers select ocean-friendly seafood on its website https://www.mcsuk.org/goodfishguide/search. Visitors can search fish species by name and retrieve an overview or detailed information on each species including a rating based on its stock status, fisheries management, and the environmental impacts of the fishing methods used. Detailed reports include additional information on the area and method of capture as well as the stock from which the fish is derived (only applicable to North-East Atlantic stocks).

The site also includes information on the state of the world’s fish stocks and maps of the world’s fishing areas including UN Food and Agriculture Organisation (FAO) fishing areas and North East Atlantic stocks provided by the International Council for the Exploration of the Sea (ICES). There is also a glossary of terms associated with fish biology and fisheries management and descriptions of various fishing methods.

For quick reference, the site includes clickable lists of Fish to Avoid and Fish to Eat and even a wallet-sized list of the Fish to Eat guide (plus phone apps) for download.
