Farmed clams are a "Best Choice" as they're raised in an environmentally responsible way, with little impact on habitats or other species.

Farmed clams are available year-round, but fresh clams may be limited in specific regions for food safety reasons. Clams are served cooked in or out of the shell, are available fresh or frozen, and can also be used in sushi.
Clams are farmed all over the world. Unlike fish raised in farms, clams and other filter feeding shellfish do not require additional feed; they simply filter their food from the natural environment .
Most concern around clams usually stems from harvesting methods such as dredging, and therefore hand harvesting is usually considered preferable. However, the farm impact is considered minimal as compared to wild harvesting and so altogether, farmed clams are considered a "Best Choice."
