All seafood species, wild caught or farmed, included in the Guide were rigorously assessed by marine scientists following stringent criteria compiled collaboratively by a number of WWF offices.
Wild-caught seafood - we examined in detail whether the fishery is sustainably managed, and whether the fishing methods used are destructive to the environment.
Farmed seafood - we looked into the impacts of disease and pollution, the use of medicine, and the origin of juveniles for farming.
