Quahogs, Mercenaria mercenaria, also known as “hard clams,” are an increasingly important commercial shellfish species in Maine, especially in the southwestern region of the coast where seawater temperatures are warmest and therefore more optimal for quahog growth. Some communities plant cultured quahogs to diversify their shellfish resources, and they can also be grown on aquaculture leases. Downeast Institute collaborated with a clammer in Trenton, Maine to pioneer techniques for farming quahogs in Maine (Beal et al. 2009). Visit DEI’s Quahog research pages to learn more about field grow-out methods.
