Super Seafood Choices

by Edward R. Blonz, Ph.D.  

The Seafood Watch Program from the nonprofit Monterey Bay Aquarium rates seafood according to its environmental and health impacts.

The following “Super Green List" meets guidelines for being ocean-friendly, high in omega-3 fats and low in contaminants (including mercury, PCBs and pesticides): oysters (farmed), Pacific sardines (wild-caught), rainbow trout (farmed), salmon (wild-caught, from Alaska), freshwater Coho salmon (farmed in tank systems in the U.S.) and albacore tuna (troll- or pole-caught, from the U.S. or British Columbia).

Other healthful green choices include arctic char (farmed), barramundi (farmed, U.S.), squid (wild-caught Atlantic) and mussels (farmed).

By the way, you may wonder why troll- or pole-caught albacore (white) tuna gets a green light, since albacore tuna is generally high in mercury. These fishing methods catch younger tuna, which have accumulated less mercury. In contrast, long-line gear (what’s typically used in the tuna industry) catches older tuna in deeper waters that have higher mercury levels.
