Before you scarf another piece of sushi, download Canada’s Sustainable Sushi Guide. This new wallet-sized guide from SeaChoice, an organization that promotes sustainable fisheries, lists seafood by its Japanese name—such as maguro (tuna)—and evaluates it based on biological, ecological, and fisheries management factors. The guide colour-codes the options with green for Best Choice, yellow for Some Concerns, and red for Avoid. A single type of fish, such as maguro, can fall into all three categories, depending on the species and how and where it was reared and caught. (Choose wild B.C. albacore.) Choices aren’t always clear-cut, but it’s a start to more responsible eating.
