Can Small Seaweed Farms Assist Kelp Scale Up?


With a $10 million U.S. Division of Agriculture (USDA) grant introduced final fall, Bigelow and a workforce from a number of universities are additionally addressing the cow burp query. Previous analysis has discovered sure seaweed feed components scale back methane-emitting burps. Researchers are additionally inspecting their influence on milk manufacturing. Value says, “If this methane discount can concurrently result in a lift in milk yield and generate larger high quality milk, then there’s a profitability risk and it could possibly be a win-win.”

Requested about nuggets of studying up to now, Value says knowledge should watch for the printed paper—it’s a five-year research. However, she provides, “There’s hope and promise.”

Small Farmers, Massive Output

Atlantic Sea Farms is constructing its enterprise on that hope and promise. The corporate presently works with 27 impartial companion farmers, primarily lobstermen, who have already got boats and kit. Their leases dot all the coast of Maine, which is even longer than California’s. Most are small, about 4 acres, however all collectively these farms add as much as round 100 acres of sugar and thin kelp manufacturing.

The corporate sees each its scale and the variety of its community as a strategic benefit in decreasing provide chain danger for giant prospects of kelp, like Entire Meals, Sweetgreen, and Every day Harvest.

Atlantic Sea Farms offers its farmers coaching and ongoing assist, free seed (valued at almost $10,000 per farm), and an iron-clad assure to purchase their harvests every spring. In flip, the contract requires farmers to attend an annual assembly to share their experiences and alternate concepts. “Fishermen are higher seaweed farmers than any of us will ever be,” Warner says.

The corporate’s present contract price is 60 cents per moist pound, so most growers earn between $40,000 and $110,000 a season as supplemental revenue, she says. The quantity is determined by the scale of the farm, their expertise stage, and fewer predictable components such because the climate. It’s a superb return on funding of each the time they put in and kit they have already got, together with boats which can be underutilized in winter.

In his second 12 months of kelp farming, lobsterman Bob Baines produced 42,000 kilos (a $25,200 paycheck), however he believes he can double that. “I’m nonetheless studying,” he says. He has utilized for a bigger lease of seven acres by the Maine Division of Marine Sources the place he shall be approved to develop 10 totally different species of seaweed. As a sign of the longer term he sees for seaweed cultivation, he’s bringing his nephew into the enterprise.

Baines estimates he has invested $20,000 to $25,000 in his farm’s infrastructure, a grid of 1,000-foot strains which can be 13 to fifteen toes aside and 6 to eight toes under the water’s floor. The kelp grows 5 to 10 toes lengthy from these strains, hanging within the ocean like honey-colored laundry.

In November, it takes Baines about three days to seed the farm with spools of sporophytes from Atlantic Sea Farms’ nursery. Engaged on a 14-foot skiff, he runs the lengthy strains by two-inch spools, unwinding the seeded twine as a companion maneuvers the boat. The much less uneven the water, the happier they’re. The springtime harvest will take about 5 days. In between, Baines checks his farm each week or so, untangling strains in frigid climate if a storm has stirred issues up.

As soon as the farmers harvest their kelp, Atlantic Sea Farms vehicles it again to its 27,000-square-foot facility 20 miles south of Portland, the place it has been situated since January. There it might course of 5 instances extra kelp in an hour than it did in a complete day on the former location, says Warner. Relying on the product software, it might blanch, shred, freeze, ferment, puree, or dry it.

Below the identical roof, the corporate additionally homes seed cultivation, product growth, and closing manufacturing, in addition to enterprise capabilities like gross sales. “It’s some of the vertically built-in firms that I’ve ever been a part of,” says Suskiewicz. “The one stage we don’t do is the precise farming, however we’re so intently built-in with our companion farms. I imply, we’re on their boats on a regular basis.”

It audits the farms all winter in order that Suskiewicz can monitor how every seed lot is rising. “We hint all the things that we do again to its mother and father.” For the autumn of 2022, he plans to supply 400,000 toes of seeded line, making Atlantic Sea Farms’ seaweed cultivation heart the most important such hatchery within the U.S.

Not All Seaweed Farms Look Alike

In distinction to Atlantic Sea Farm’s community of many, small growers, enterprise fashions that faucet fewer, bigger farms have been rising in Alaska, which solely started issuing kelp farming permits in 2016. For instance, San Francisco-based Blue Evolution has partnerships with simply two farms in Kodiak, Alaska, however they’re geared to ship 300,000 moist kilos of kelp in 2022. (Atlantic Sea Farms anticipates 1.2 million moist kilos of kelp from 27 farmers.)

Alaska is issuing big leases in comparison with the so-called experimental leases that make up most of Maine’s trade. A single farm within the Gulf of Alaska can stretch as massive as 132 acres, in response to Melissa Good of the Alaska Sea Grant Marine Advisory Program. She provides that Alaska’s complete aquaculture acreage might balloon 1.5 instances to a complete of two,200 acres if all 23 pending allow functions are accepted for seaweed farms and people who elevate seaweed and shellfish concurrently. That’s greater than 1,600 soccer fields of ocean farms.

Along with the construction of its farming community, Blue Evolution has veered from Atlantic Sea Farms’ vertically built-in mannequin by emphasizing partnerships. For seed, it’s collaborating with the Nationwide Oceanic and Atmospheric Administration (NOAA) Fisheries on the Kodiak Fisheries Analysis Heart. And it contracts the Solar’aq Tribe in Kodiak to deal with seaweed processing every spring.

Blue Evolution additionally works throughout the border: it grows 250,000 moist kilos of sea lettuce in tanks at a land-based natural farm in Baja Mexico. It had been producing pasta and popcorn with this seaweed however is discontinuing product manufacturing.

“We began with the intention of being vertically built-in and having our personal retail model and promoting that product as Atlantic Sea Farms was doing, however COVID, frankly, made that powerful,” says founder Beau Perry. For now, the corporate is concentrated on working with growers, processing, and wholesale alternatives.
