January 17, 2020 — Seaweed, or sea vegetables, have been on a growth trajectory for the past 10 years. What started as a small industry has blossomed into a sustainable economic engine for coastal communities from New York to Maine, who have faced slowdowns in other once-dominant fisheries.
“Five percent of Maine’s aquaculture lease and limited-purpose aquaculture LPA holders (47 individuals) also hold a commercial lobster fishing license. Out of those 47, 12 of them farm kelp. Out of 60 total kelp farmers in Maine, that’s 20 percent,” says Afton Hupper of the Maine Aquaculture Association. “Lobstermen are already equipped with much of the gear required to start a kelp farm,” adds Hupper. “It is a good way to diversify and supplement their income.”
In Maine, harvest of all seaweed species peaked in 2018, with 22 million pounds, according to Maine Department of Marine Resources data. But a recent Maine Supreme Judicial Court ruling has meant changes to the rockweed industry. Until this year, wild rockweed (Ascophyllum nodosum) — with landings consistently making up more than 95 percent of all landings statewide — was harvested along coastlines. Last year, it was valued under $1 million at the docks.
But now, permission from landowners is required to harvest, since the court determined rockweed in the intertidal zone to be the landowner’s private property. Maine landowners now have a say in how rockweed is harvested, as well as the opportunity to benefit from the industry.
