Green Chefs Blue Ocean has completed an astoundingly useful resource for sustainable seafood information. The information is hosted at OceanFriendlyChefs.org
and includes an in-depth interactive course covering the sustainability of wild fin-fish, farmed fin-fish, shellfish, shipping practices, and much much more. If you have any questions about sourcing sustainable seafood for your restaurant, this site has the answer. Registration is required for the online course, but it is free.
