Seafood is a delicious and healthy meal choice, but for many consumers, where the fish comes from and how it was obtained are increasingly bigger concerns. As a result, several of Canada’s largest grocery chains have committed to sustainable seafood policies, meaning that they promise to carry only seafood that is caught or farmed in a manner that protects the individual species and the ecosystem. But do you know what to look for? Sustainable seafood program SeaChoice, formed by five Canadian conservation organizations—the Canadian Parks and Wilderness Society, the David Suzuki Foundation, the Ecology Action Centre, the Living Oceans Society and the Sierra Club British Columbia—has made finding the best option easy.

Plug in your seafood choice at seachoice.org to see if it falls under one of the following categories.

Best Choice (Green): “This species is currently fished/harvested sustainably. Enjoy, while supporting responsible fishing and coastal livelihoods.”

Some Concerns (Yellow): “Seafood that should be consumed infrequently or when a green choice is not available. There are conservation concerns with the current populations or practices in this fishery.”

Avoid (Red): “Do not purchase these fish for now. They come from sources that have a combination of problems: habitat damage, discard of unwanted species, poor management, low populations, can be easily harmed by fishing or may be listed by governments as endangered.”
