The Monterey Bay Aquarium’s Seafood Watch app for smartphones
The Monterey Bay Aquarium's Seafood Watch app for smartphones (Monterey Bay Aquarium)

You've heard us blather on about sustainable seafood and the need for environmentally responsible shopping and dining choices. You can't just assume that your favorite sushi chef or fishmonger is avoiding seafood species threatened by overfishing. That's why the Monterey Bay Aquarium Seafood Watch folks offer a smartphone app as well as an old-school paper cheat sheet that folds up and tucks in your wallet. It's so you can check and make sure that the lovely Chilean sea bass on your plate did not come from Chile. Caught in the Falkland Islands? You're good to go.

Now you may not even have to think about that when you dine at restaurants in 75 national parks across the country. The National Park Service just announced that the concessionaires for many of its 250-plus cafes, restaurants and other eateries have begun using the Seafood Watch list as part of its Healthy Parks, Healthy People initiative, which calls for more sustainably sourced ingredients across the board and a greater focus on healthful dining choices. How it all plays out depends on the park, but Aramark, one of the large concessionaires with restaurants in Denali, Olympic and Mesa Verde national parks, already is a Seafood Watch national partner -- as befits the concession holder for the Monterey Bay Aquarium.

They're not the only ones. Among the Bay Area restaurants that have partnered with Seafood Watch: San Francisco's Americano, Credo, Farallon and Waterbar. Get more details and download the updated spring 2013 Seafood Watch guide and smartphone app at www.montereybayaquarium.org.
