Quality Seed. Local Commitment.

At Merrymeeting Shellfish Company, we blend expertise in shellfish, sustainability, and science to run a state-of-the-art hatchery. Based in Harpswell, Maine, we use the clean, cold waters of Middle Bay to produce top-quality shellfish seed. Our mission is to support East Coast growers with reliable, high-performance stock that helps drive success.

We’re proud to be an independent, American-owned company—deeply committed to supporting local aquaculture and strengthening coastal communities through responsible, hands-on partnerships.
