The Maine Seaweed Council (MSC) produces this “Harvester’s Field Guide to Maine Seaweeds” as a supplement to their “Harvest Guidelines for Maine Seaweeds.” The information in this Field Guide complements and supports the recommendations in the Guidelines. Using both documents, current and future harvesters will be able to make more informed choices about what, when, where and how they harvest – a crucial step towards sustainable harvesting in Maine, and the primary mission of the Maine Seaweed Council.
