6. Freshwater Coho Salmon (farmed in tank systems, from the U.S.)

Freshwater coho salmon is the first—and only—farmed salmon to get a Super Green rating. All other farmed salmon still falls on Monterey Bay Aquarium’s Seafood Watch “avoid” list for a few reasons. Many farms use crowded pens where salmon are easily infected with parasites, may be treated with antibiotics and can spread disease to wild fish (one reason Alaska has banned salmon farms). Also, it can take as much as three pounds of wild fish to raise one pound of salmon. Coho, however, are raised in closed freshwater pens and require less feed, so the environmental impacts are reduced. They’re also a healthy source of omega-3s—one 3-ounce serving delivers 1,025 milligrams.
