Portland Press Herald: State regulators are drawing up the first management plan to protect rockweed, a common seaweed on the Maine coast that supported a $20 million industry in 2012 and is likely to attract even more intensive harvesting as global markets expand.
The number of licensed rockweed harvesters in Maine climbed from 29 to 59 between 2004 and 2012, when harvesters gathered about 14 million pounds of the marine plant. Rockweed, which clings to rocks in the intertidal zone, sells for only 3 cents a pound at the dock. But the harvest was worth $20 million after it was processed for use in a range of products: Pharmaceuticals, nutritional supplements, cosmetics, fertilizers, animal feed and horticultural additives.
