Maine is a special place, especially for seaweed and urchins. The cold clean waters of downeast Maine create ideal growing conditions for a large variety of seaweeds. Our coastal communities are rooted in the traditions of living from the sea and encompass a great respect for our marine resources. Sustainably farmed seaweed and urchins from Maine are arguably the finest in the world. We are committed to supporting our local Maine communities.
