Since 1950 about a third of all fished species worldwide have collapsed. Thus, making sustainable seafood choices is important. When you’re ordering sushi, is that maguro (tuna) more sustainable than the sake (salmon)? To find out, download Monterey Bay Aquarium’s latest guide or app (seafoodwatch.org), which categorizes sushi into best choices, good alternatives and those to avoid. Sake is generally a better choice than maguro, but in many cases it depends on where the fish was sourced. So ask your server where your sushi came from.
