Geoduck farms are spreading around the coastal Northwest. The geoduck, the largest clam in North America (and pronounced GOO-ee-duck), is a bivalve with a three-foot neck. They can live to be more than 150 years old.
For years, divers have harvested the delicacies from the salt waters of Washington, Alaska and British Columbia. Now — like oysters and other shellfish — they're being farmed by entrepreneurs.
