Remember orange roughy? It’s a fish that was plentiful on restaurant dinner menus a generation ago. But it’s been overfished for years, and if you know a thing or two about sustainable seafood, you know full well that orange roughy is on the “Avoid” list. Costco, under pressure from Greenpeace and a Change.org campaign, has pledged to stop selling orange roughy, Chilean sea bass, shark, Atlantic halibut, Atlantic cod, Greenland halibut, grouper, monkfish, red fish, skates and rays, swordfish, and bluefin tuna, which all face a variety of environmental stresses.
