BAR HARBOR, MAINE - MAY 21: Joanna Fogg, owner of the Bar Harbor Oyster Co., on her oyster farm in the Mt. Desert Narrows waterway on May 21, 2026 in Bar Harbor, Maine. In a recent report, the Gulf of Maine Research Institute notes that the Northeastern United States is the fastest-growing market for shellfish and that Maine is the fastest-growing state in the Northeast, with annual revenue projected to reach $20 million by 2028. Democratic U.S. Senate candidate Graham Platner, an oyster farmer, has drawn attention to the business as the presumptive Democratic Senate nominee who will run against incumbent Sen. Susan Collins (R-ME). (Photo by Joe Raedle/Getty Images)
