Information was compiled from four main sources: the Monterey Bay Aquarium, the Marine Conservation Society, FishWatch, and the Greenpeace Red List. Individual entries have lists of sources, and I have aimed to reach a verdict solely based on the information contained in the sources. MCS ratings of 1-2 are considered "sustainable", and a rating of 3 is acceptable if other sources label the fish as sustainable. Information from these sources was supplemented by data directly from the IUCN red list. A IUCN rating of "least concern" was considered "sustainable".

Where there was serious contradiction, or the differences between sustainable and unsustainable sources of a fish was too involved, I have erred on the side of caution.

With some fish labeled unsustainable there will be exceptions where you can source them sustainably from specific places. To highlight these sources and mention updates, I've started a twitter stream at @which_fish.
