A seafood guide for Hong Kong - How were the different species assessed for the guide?

The seafood species we have included in the guide are the most common species on sale in Hong Kong. All species were assessed using rigorous criteria for either wild caught, or farmed species, developed collaboratively by a number of WWF offices, including Hong Kong. For wild-caught seafood, we examined in detail whether the fishery is sustainably managed, and whether the fishing methods are destructive to the environment. For farmed seafood, we looked at the impacts of disease, pollution, the use of medicine, and where the juvenile animals come from. Each assessment has been fine-tuned within WWF. We have also verified our own assessments with one or several independent experts, a painstaking process that took a year to complete.
