What are the FishSource scores?

FishSource does not have its “own” sustainability rating system, rather providing the user with a straight forward, clear, information on how international, accredited systems would rate / have rated the fisheries. Scores make use of commonly reported numbers from stock assessments but they do not define a fishery as “good” or “bad”. Fisheries can be ranked against one another and give insights into how other groups would score a fishery against current measures of sustainability. Scores currently relate to the Marine Stewardship Council (MSC) standards, which in turn rely on international organizations’ criteria – e.g. International Council for the Exploration of the Sea – ICES. Scores have been developed in a way that a score of 8 has a parallel of an 80 MSC rating – i.e., “unconditional passing” on that criteria, towards MSC certification. Same rational applies to, e.g., a FishSource score below 6 → “the fishery will be ineligible for certification” [MSC standards].
