BlueOcean.org has developed a method that translates information about fisheries and aquaculture into ranked lists of seafoods.
Since publishing our first seafood guide (5), we’ve produced wallet-sized guides and more detailed evaluations in our book Seafood Lover’s Almanac (6) and on our website www.blueoceaninstitute.org. Consumers have shown surprising interest and willingness to act. Consumers who understand, for example, that Chilean seabass is a market pseudonym for Patagonian toothfish (Dissostichus eleginoides) and that rampant illegal fishing is depleting toothfish and killing endangered albatrosses, are more likely to make another choice.
Our ranking process is standardized, transparent, and updateable. We evaluate wild species and farmed seafood to account for the different conservation concerns associated with wild-capture fisheries and aquaculture. Our analysis is based on five criteria: for wild species, life history characteristics, current level of abundance, habitat quality, management effectiveness, and bycatch. Farming systems are evaluated for their on-site operations (e.g., open net pens versus closed re-circulating tank systems), feed composition, water quality, biological effects (e.g., species is native versus nonnative), and ecological effects (e.g., sensitivity of surrounding habitat). By answering a suite of questions within these categories, we create a comprehensive profile for each species, probing and citing published government reports, scientific journal articles, and industry and trade reports. We use information in the profile to score each species and then for clarity, convert the score into a color-coded seafood recommendation.
