Rainbow Trout (farmed)
Though lake trout are high in contaminants, nearly all the trout you will find in the market is farmed rainbow trout. In the U.S., rainbow trout are farmed primarily in freshwater ponds and “raceways” where they are more protected from contaminants and fed a fishmeal diet that has been fine-tuned to conserve resources.Now that is a suprise, I love trout!
Salmon (wild-caught, Alaska)
To give you an idea of how well managed Alaska’ssalmon fishery is, consider this: biologists are posted at river mouths to count how many wild fish return to spawn. If the numbers begin to dwindle, the fishery is closed before it reaches its limits, as was done recently with some Chinook fisheries. This close monitoring, along with strict quotas and careful management of water quality, means Alaska’s wild-caught salmon are both healthier (they pack 1,210 mg of omega-3s per 3-ounce serving and carry few contaminants) and more sustainable than just about any other salmon fishery
Freshwater Coho Salmon (farmed in tank systems, from the U.S.)
Fresh water 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’sSeafood 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.
