1. SeaChoice

Make ocean-friendly seafood choices for today and tomorrow with this easy-to-use SeaChoice app. It categorizes your options as “best choice” (green), “some concerns” (yellow) or “avoid” (red), depending on abundance, environmental impact and whether the species are caught or farmed responsibly. You can search by species (or sushi name!) or colour category.
