PORTLAND, Ore. — Whole Foods is trying to clear some murky waters for seafood shoppers.
The grocery chain Monday launched a color-coded rating program, with the help of Monterey Bay Aquarium and Blue Ocean Institute, that measures the environmental impact of its wild-caught seafood.
The program is the latest move by a major grocer to change seafood policies as concern rises about overfishing and the environmental effects of certain fishing methods.
Seafood is given a green, yellow or red rating. A green rating indicates the species is relatively abundant and is caught in environmentally friendly ways. Yellow means some concerns exist with the species’ status or the methods by which it was caught. A red rating means the species is suffering from overfishing or the methods used to catch it harm other marine life or habitats.
