With the massive range of fish and oceanic species offered at sushi restaurants today, it’s a challenge knowing which ones are sustainable to eat. Thankfully we’ve discovered the Blue Ocean Institute’s guide to ocean friendly sushi.

Created in collaboration with the Monterey Bay Aquarium, the Blue Ocean Institute works toward ocean conservation through efforts like this guide.

For novice sushi eaters, the guide even has a “how to eat sushi” section with basic tips and myth busters, such as why you shouldn’t use chopsticks for sushi.

Five rankings help distinguish between the relatively abundant species and those with problems such as overfishing, high bycatch and poor management.

Text “FISH” and the species name to 30644 for instant sustainability information when you need it. Or if you have a PDA, then visit www.fishphone.org to download a cell phone-friendly seafood guide.
