Keeping up with exactly which fish are endangered and which are sustainable is tough because the list keeps changing. It is a good idea, to check in regularly with folks who keep a close eye on the situation, such as the Monterey Aquarium (Monterey Bay Aquarium, California). You might even want to print out an up-to-date, wallet-sized guide to take with you when you go to the fish store or supermarket.
The fish that I know are ok right now are Tilpia Catfish (from the US) Wild gulf shrimp Black cod Wild pacific salmon
