The biggest problem with fish is that its public relations have, arguably, been too good. A handful of well-known species -- including salmon, tuna, sea bass, and swordfish -- have captured the public attention, and its palate. Fishing fleets sail far and wide to collect these restaurant favorites; in the process, they have often overfished many of the classics, driving prices up and breeding populations down.
So how can you satisfy your craving for finny friends without blowing all your money or destroying the ocean? The answer is simple: Eat weird fish. The species that you've heard of, that you grew up eating, are the same ones that are currently struggling to survive. On the other hand, there are dozens that you probably haven't heard of that are much less at risk and would taste great on your plate. Several resources, notably the Monterey Bay Aquarium's Seafood Watch, offer lists of sustainable fish. Monterey Bay, in fact, even offers a smartphone app that can make it easy to scan the menu for sustainable choices.
In fact, while it might be overstating to claim that your fish-eating choices can actually help the environment, there are some invasive species that are crowding out more popular choices. If you can develop a taste for swamp eel, walking catfish or rusty crawfish, you could conceivably open up a little more space for other species. In the meantime, though, here are a few of our favorite less-common fish choices:
