Home of “Dark Harbour Dulse”.


Atlantic Mariculture has been harvesting and packaging only the finest hand-picked Dulse since 1974. In 1993, we became one of the first organically certified sea vegetable producers in the world.

Located on Grand Manan Island in the Bay of Fundy, Atlantic Mariculture has made it our mission to share the highest quality Dulse and sea vegetables with the rest of the world. With cliffs that shade the Dulse from early daylight, along with the cold, clear North Atlantic waters, “Dark Harbour Dulse” is darker, thicker and more flavourful than dulse grown anywhere else.
