There may be plenty of fish in the sea, but finding one for dinner can make your head swim. Feel like salmon? U.S. tank-farmed freshwater coho salmon is environmentally sound, while Atlantic farmed varieties usually aren't. Wild-caught Alaskan varieties get great marks, but you can't trust that salmon simply marked "wild" truly is. Here's how to navigate.
1. Download a Monterey Bay Aquarium Seafood Watch pocket guide for best picks, fish to avoid, and good alternatives. Go to Mobile.SeafoodWatch.org for apps.
2. Text the word FISH and a species name to 30644; the Blue Ocean Institute will send a sustainability rating and better options.
3. Look for the Marine Stewardship Council label on wild-caught fish in stores and restaurants—it's the most rigorous certification there is.
