MAINE: In the land of lobster, seaweed is finding its niche

December 7, 2021 — The annual Maine harvest of seaweed pales in comparison to lobster landings in pounds and value. Yet increasingly, lobstermen have joined other entrepreneurs in growing, harvesting and marketing Maine seaweed. Seen as another means of diversifying the state’s commercial fishing industry, it is turning into a multimillion-dollar industry and keeping in-shore fishermen busy during lobster’s off season. 

Rockweed, common along the Maine coast, accounts for about 95 percent of commercially harvested seaweed. It’s used for packing lobsters, as fertilizer and a nutritional additive for pet and livestock feed, and to extract alginate, used to thicken foods, cosmetics and even paint. 

But a smaller but growing market is for kelp, sugar kelp, dulse and Alaria, edible sea vegetables grown and harvested for nutritional and flavor supplements in a variety of foods. 

“People are recognizing its health benefits, its environmental benefits, and it tastes great,” Island Institute’s Sam Belknap said. The institute recently supported new aquaculturists, including seaweed growers, in a program for fishermen.

Huffman-sponsored bill seeks grant funding to restore kelp forests

August 10, 2021 — A bill sponsored by U.S. Rep. Jared Huffman to protect marine ecosystems in northern California recently got its first hearing in a subcommittee he chairs.

The California Democrat included H.R. 4458, the Keeping Ecosystems Living and Productive (KELP) Act, before the House Natural Resources Subcommittee on Water, Oceans, and Wildlife during a 29 July hearing. The bill calls for creating a new grant program within NOAA to fund projects to restore kelp forests. It calls for USD 50 million (EUR 42.6 million) in funding annually from the 2022 fiscal year, which starts on 1 October, 2021, through fiscal year 2026.

Kelp at the Crossroads: Should Seaweed Farming Be Better Regulated?

July 20, 2021 — On Vancouver Island, seaweed is abundant, diverse, useful, and symbolic. Indigenous peoples have used it for centuries for food preparation, fishing, and as a cultural and spiritual touchstone. On the island’s southwest coast, Dr. Louis Druehl started farming and researching kelp in the late 1970s and says he has dedicated his life to it “and loved every minute.” He mentored seaweed farmer Kristina Long, who now grows bull kelp over about 40 acres, and harvester Amanda Swinimer, who wades out into waist-deep water at low tide to carefully hand-cut blades of winged kelp in just the right spot to ensure regrowth.

These tiny operations barely create ripples within the vast coastal landscape, but kelp—here and elsewhere in North America—is at a crossroads.

In recent years, seaweed has been promoted around the globe as an overlooked, multifaceted climate solution: a sustainable food and biofuel source, a feed that reduces methane emissions from cattle, and a tool with the potential to absorb massive quantities of carbon from the atmosphere (although much more research is needed to determine how farms might actually contribute to sequestration). As a result, companies looking to capitalize on those promises are turning up in far-flung coastal communities with big plans.

Take Cascadia Seaweed. The company arrived on Vancouver Island soon after it was founded in 2019, and set a goal to farm 1,200 acres of the ocean there by 2025; its larger “stretch goal” is over 6,000 acre. In Alaska, Seagrove Kelp Co. has 127 acres in operation and 700 in the permitting phase. And in Maine, the continent’s seaweed-farming hub, Running Tide’s vision involves millions of biodegradable buoys attached to lines of kelp offshore.

The Future of Ocean Farming

June 29, 2021 — Called regenerative ocean farming, this model involves growing shellfish and kelp in underwater gardens.

For all his life, Alaskan fisherman Dune Lankard has looked to the sea—for food, work and purpose. “I started fishing when I was five,” says Lankard, a member of the Athabaskan Eyak community, an Indigenous group from the Copper River Delta. “I really don’t have any skills beyond the ocean.”

Born in 1959, the same year Alaska became a state, Lankard has witnessed various natural and man-made disasters—including the commoditization of Indigenous peoples’ traditional fishing way of life—that have disrupted his industry and homeland. “As an Indigenous fisherman, I’ve seen it all,” he says.

In 1964, a massive magnitude 9.2 earthquake, fittingly called the Great Alaska Earthquake of 1964, triggered a swell of tsunamis that killed more than 130 people and devastated fisheries. Exactly 25 years later, an Exxon Valdez oil tanker struck Bligh Reef in the Prince William Sound, spewing 10.8 million gallons of crude oil into the sea. The spill affected 1,300 miles of water and coastline, much of which is still considered to be in recovery.

Now, Alaskan fishermen are facing another urgent problem. Alaska is already feeling the effects of climate change, as the warming oceans have wreaked havoc on ecosystems of krill, wild kelp forests, salmon and birds. That’s all on top of the lingering losses caused by the 1989 oil spill. Before the Exxon spill, the Sound’s spring run of herring totalled more than 200,000 tons returning home. Today, there are only 4,000 tons returning annually. Lankard recently sold his fishing permit after several consecutive bad seasons.

To help mitigate the effects of warming waters, Lankard is now embracing an approach known as regenerative ocean farming, which involves growing seaweed and shellfish in small underwater gardens. Once a commercial fisherman, Lankard now mostly farms kelp.

“Alaska has always been based on extraction. We’re a natural resource extraction state,” says Lankard. “What regenerative ocean farming does is create a new regenerative economy that’s based on conservation, restoration and mitigation, as opposed to more extraction of resources.”

The burgeoning concept of regenerative ocean farming was developed and named by Bren Smith, a Canadian commercial fisherman turned ocean farmer. He believes ocean farming is the new farming model of the future.

From Maine’s warming waters, kelp emerges as a potentially lucrative cash crop

June 28, 2021 — One bright, brisk morning last month, Colleen Francke steered her skiff a mile off the coast of Falmouth and cut the gas. A few white buoys bobbed in straight lines on the water. Francke reached down and hoisted a rope.

She has been lobstering for a decade and a half, she says, but as climate change warms local waters and forces lobsters northward, she’s been finding it harder to envision a future in that industry.

So, for the last two years, she’s been developing a new source of income. Heaving the rope aloft, she showed off her bounty: ribbons of brown, curly sugar kelp, raised on her 10-acre undersea farm.

Kelp, a seaweed more often thought of as a nuisance by fishermen, is emerging as a potentially lucrative crop, hailed for its many uses as a miracle food to an ingredient in bioplastics to a revolutionary way to feed beef cattle. And Maine officials, confronting a likely decline of the state’s iconic lobster fishing industry in coming decades, are now looking to kelp farming as a possible economic and environmental savior.

The state is working with local institutions to support training and grants for entrepreneurs such as Francke willing to move into kelp farming or other aquaculture ventures. It also labeled kelp a “natural climate solution” in its recently-released Climate Action plan. The goal, officials say, is to dramatically expand kelp farming as part of a reinvention of Maine’s seafood industry — and imagining a future in which kelp from Maine is held in something akin to the esteem that Maine lobster is now.

Applications for aquatic farming in Alaska drop due to pandemic, and kelp is favored over shellfish

June 2, 2021 — Alaska interest in growing kelp continues to outpace that of shellfish, based on applications filed during the annual window that runs from January through April.

The number of 2021 applicants for aquatic farming dropped to just seven, reversing a steady upward trend that reached 16 last year, likely due to a “wait and see” approach stemming from the pandemic.

“We had people whose personal situations changed because of COVID. They became home-schooling parents, things like that, where they can no longer dedicate the time they thought they were going to have out on a farm site,” said Michell Morris, permit coordinator at the Alaska Dept. of Fish and Game. The agency partners with the Dept. of Natural Resources, which leases the lands where aquatic farming takes place.

Researchers rush to understand kelp forests as harvesting increases

April 22, 2021 — The kelp forests of the oceans are a habitat for a wide range of marine species, rivaling even the great tropical forests for sheer richness of biodiversity, according to scientists from the KELPER project, which studies these marine algae ecosystems.

The kelp species, or marine algae, that make up these seaweed strands anchored to rocks on the seafloor are typically Macrocystis pyrifera, or giant kelp, and Lessonia trabeculata, known locally as huiro palo. The largest natural reserves of these algae are found off the coast of Chile and southern Argentina, according to the United Nations Food and Agriculture Organization (FAO). Chile is the main beneficiary of this abundance, with an important industry dedicated to kelp harvesting, primarily L. trabeculata, making the country the world’s largest producer of macroalgae.

Algae contain a carbohydrate called alginate that’s used as a thickener in a large number of products in the food industry, such as desserts, ice creams, dairy products, sauces and condiments. It’s also used in the textiles and pharmaceuticals industries, including in the production of creams and toothpaste.

Until 2005, these long strands of kelp were collected on the beach by fisher-gatherers when, after a swell, the waves pulled them up from the seafloor and deposited them on the shore. Since then, increasing demand for alginate — a market estimated at $1 billion a year, according to a KELPER Project report — has driven the industry to start harvesting the kelp directly from the source in the sea, in a practice known locally as barreteo. According to the most recent figures published by the Chilean National Fisheries Service (Sernapesca), 40,261 tons of L. trabeculata were cut from the seafloor this way in 2018.

‘Run The Oil Industry In Reverse’: Fighting Climate Change By Farming Kelp

March 1, 2021 — In the race to stall or even reverse global warming, new efforts are in the works to pull carbon dioxide out of the air and put it somewhere safe.

One startup in Maine has a vision that is drawing attention from scientists and venture capitalists alike: to bury massive amounts of seaweed at the bottom of the ocean, where it will lock away carbon for thousands of years.

The company is called Running Tide Technologies, and it’s prototyping the concept this winter. On a recent day in the Gulf of Maine, boat captain Rob Odlin says the task itself isn’t much different from any other in his seafaring career, whether chasing tuna or harvesting lobster.

“We’re just fishing for carbon now, and kelp’s the net,” he says.

Running Tide CEO Marty Odlin — the boat captain’s nephew — comes from a long line of Maine fishermen, and once imagined he would continue the tradition. But he watched as the warming climate drove major shifts in fish populations, while regulators put a lid on how much could be taken from the sea.

Eat More Kelp campaign launched by climate change activists in North America

November 10, 2020 — Climate change is the impetus driving the new Eat More Kelp campaign in North America, which seeks to “change the trajectory of culinary culture in the United States and Canada to include more carbon-capturing, ocean-grown domestic sea vegetables,” according to its organizers.

A collaboration of activists, regenerative ocean farmers, and climate groups are behind the campaign’s creation. The initiative was announced in tandem with the founders of The Kelp Fund, Inc. launching a new website and e-commerce platform, which offers Eat More Kelp-branded merchandise for “concerned citizens and organizations around the world who are seeking impactful ways to raise awareness about how to fight climate change,” it said in a press release.

Training Builds on Growing Popularity of Kelp Farming

May 14, 2020 — The following was released by NOAA Fisheries:

For 28 years Riley Starks has fished near Lummi Island, Washington, netting Chinook, coho, sockeye, pink, and chum salmon. He also owns a bed and breakfast on the island that specializes in providing guests with unique skill-building experiences. They can smoke salmon and make jam and ikura, which is seasoned and cured salmon roe. He has observed many of the Puget Sound area’s 17 species of kelp—or brown macroalgae—while tending his nets.

He jumped at the chance to further build his own skills as part of intensive training in seaweed farming sponsored by Washington Sea Grant. In early February, he joined about 30 seaweed enthusiasts, including representatives of four tribes, seven military veterans, several commercial fishermen, and shellfish farmers. They took a three-day deep dive into the seaweed industry.

“The training was comprehensive and excellent,” Starks said. “I particularly appreciated the emphasis on the importance of working with the tribes early in the process—they have unique and important rights that must be respected.”

Seaweed farming has taken off in recent years in Maine and Alaska, which have dozens of farms and more in the works. Despite the increase in domestic production, the United States remains the fifth largest importer of seaweed for human consumption. Seaweed is added to many products, such as salsas, sauces, salads, seasonings, and pastas, used in restaurants and at home. That market demand, plus the health and environmental benefits of seaweed farming, have generated interest in Washington state. Uncertainty exists about the permitting process and access to local processing facilities, given the newness of kelp farming in local waters.
