Urchins and oysters eyed for local farming GOULDSBORO — An organic seaweed farmer is seeking to raise oysters and sea urchins in deep water at an existing ocean site, where the marine species’ growth will be tracked to test their potential as sustainably harvested seafood in years to come. Last year, Springtide Seaweed LLC founder Sarah Redmond secured a 10-year aquaculture lease to grow sugar kelp, skinny kelp, alaria and dulse west of Gouldsboro’s Stave Island in Frenchman Bay. Based in South Gouldsboro’s Bunkers Cove, Redmond also manages a 35-acre seaweed farm off Preble Island near Sorrento for lease holder James West. Springtide grows, harvests and processes its crops into dried seaweed powder and flakes for food producers. The company also has a line of salt-free seasonings and its own hatchery.
