“Restorative aquaculture” potential greatest in North Sea, East China Sea, and Southern California

October 15, 2019 — Combined commercial shellfish and seaweed aquaculture have significant potential to provide sustainable food and jobs while restoring marine ecosystems in Europe’s North Sea, the East China Sea, and Southern California.

A new study published in PLOS ONE finds that every inhabited continent has marine regions well-suited for the kind of shellfish and seaweed aquaculture that benefits both ecosystems and people by filtering polluted waters, providing habitat for commercially valuable species, and generating steady food and jobs. For shellfish, the potential was greatest in Europe, Oceania, and North America, while for seaweed, it was greatest in Europe, Asia, Oceania, and South America.

Shellfish and seaweed farms are a growing industry in Alaska

August 28, 2019 — Underwater and out of sight are the makings of a major Alaska industry with two anchor crops that clean the planet while pumping out lots of cash: shellfish and seaweed.

Alaskans have applied for over 2,000 acres of new or expanding undersea farms, double the footprint from two years ago, ranging from .02 acres at Halibut Cove to nearly 300 acres at Craig.

Nearly 60% of the newest applicants plan to grow kelp with the remainder a mix of kelp and/or Pacific oysters, said Cynthia Pring-Ham, aquatic farming coordinator at the Alaska Department of Fish and Game, which issues the permits. Fish and Game partners with the state Department of Natural Resources, which leases the tidal and submerged lands for farms.

Seaweed Farmers in Alaska Gear Up for Large Haul

May 29, 2019 — The largest commercial harvest of seaweed in Alaska is taking place this month.

Blue Evolution, a California-based company that cultivates, harvests and distributes Alaska-grown seaweed, is expected to haul in up to 200,000 pounds from waters near Kodiak Island within the next two weeks. Previous harvests have been a fraction of that size, but, as the mariculture industry grows in Alaska, Blue Evolution is also expanding.

Working with local resident farmers, the company produces seed from wild seaweed plants and grows them into kelp starts in an onshore hatchery at the federal government’s Alaska Fisheries Science Center Kodiak Laboratory. Blue Evolution then supplies seeded string to local farmers who plant them onto longlines in late fall, cultivate their crops during winter and harvest in spring.

The company is collaborating with the University of Alaska and Alaska Sea Grant on seaweed research aimed at developing cost-effective cultivation methods for several native species. Seaweed farming is a growing, multibillion-dollar industry worldwide and presents a new economic opportunity for coastal Alaska.

“It suits my family because we set gillnet for salmon during the summer and supplement our income with seaweed farming during winter,” said Lexa Meyer, who co-owns and operates Kodiak Kelp Co. with her husband.

Life in the North Atlantic depends on this floating seaweed

May 15, 2019 — ‘THERE’S NOTHING LIKE it in any other ocean,’ says marine biologist Brian Lapointe. ‘There’s nowhere else on our blue planet that supports such diversity in the middle of the ocean—and it’s because of the weed.’

Lapointe is talking about a floating seaweed known as sargassum in a region of the Atlantic called the Sargasso Sea. The boundaries of this sea are vague, defined not by landmasses but by five major currents that swirl in a clockwise embrace around Bermuda. Far from any mainland, its waters are nutrient poor and therefore exceptionally clear and stunningly blue.

The Sargasso Sea, part of the vast whirlpool known as the North Atlantic gyre, often has been described as an oceanic desert—and it would appear to be, if it weren’t for the floating mats of sargassum.

The seaweed may seem unremarkable at first glance—just bunches of drifting plant matter—but as Lapointe has helped illuminate through his work, sargassum is the basis of a complex ecosystem that nurtures a stunning array of marine life. It serves as a mobile shelter and a movable feast.

For 36 years Lapointe, a biologist with Florida Atlantic University’s Harbor Branch Oceanographic Institute in Fort Pierce, has combed the Sargasso Sea, observing sargassum by satellite and experiencing it firsthand in scuba gear. He wanted to figure out where the weed comes from, how it moves, what it sustains, and what sustains it—and to unravel the complex relationship sargassum has with other forms of marine life, from seahorses to great white sharks. Only by learning about this vital resource, he says, can we protect it from potential threats, such as ocean acidification and pollution.

MAINE: Midcoast businesses say court ruling on seaweed harvest could be devastating

May 10, 2019 — Two Waldoboro businesses are grappling with a March court ruling that could restrict seaweed harvesting throughout the state.

Both North American Kelp, at 41 Cross St., and Ocean Organics Corp., at 141 One Pie Road, have based their business models on sustainable rockweed harvesting, parlaying the natural resource to create jobs and grow their companies.

On March 28, the Maine Supreme Judicial Court ruled that rockweed along the seashore isn’t public property in a 22-page opinion upholding a 2017 ruling by the Washington County Superior Court.

Amid aquaculture boom, report guides investors toward sustainability

May 9, 2019 — Aquaculture, the commercial farming of finfish like salmon, shellfish and seaweed, has exploded over the past 30 years, becoming a nearly $250-billion industry globally. More than half of all seafood now comes from farms, and that percentage is projected to rise if the human population expands, as expected, to 9.7 billion people over the next 30 years. However, environmental problems currently bedevil the aquaculture industry and a consensus on the most sustainable practices has yet to emerge.

A new report released May 8, “Towards a Blue Revolution,” aims to guide the private sector, NGOs and policymakers toward better aquaculture strategies that can both meet the growing global seafood demand and operate “in harmony with ocean ecosystems.”

“Transforming how we produce seafood through strategic investment in innovative, more sustainable production methods may ultimately represent the difference between a healthy, abundant, and profitable food system, and one that degrades the environment, destroys value, and fails to meet the growing food security challenge,” the report states.

Published by the Virginia-based environmental non-profit the Nature Conservancy and the New York-based impact investment firm Encourage Capital, the report urges the seafood industry to shift away from “business as usual” aquaculture practices. It argues that equally lucrative and more sustainable forms of aquaculture exist that investors would do well to nurture.

After Growing Like A Weed For Years, Maine’s Seaweed Industry Faces New Restrictions

May 6, 2019 — Maine’s seaweed business has grown like a weed in recent years, with proponents touting it as both a “superfood” and an economic generator for the rural state — but the industry is now facing sticky new restrictions.

Maine has a long tradition of seaweed harvesting, in which the algae is gathered for a wide variety of commercial uses, including some popular food products. Now, a recent court ruling could dramatically change the nature of the business in Maine, which has seen the harvest of the gooey stuff grow by leaps and bounds in the last decade, industry members said.

The state’s highest court ruled last month that permission from coastal landowners is needed for harvesting rockweed, a type of seaweed that’s critical to the industry. The Maine Seaweed Council, an industry advocacy group, has called the ruling “a disappointing setback” that will force harvesters to adjust.

The court’s decision could mandate the implementation of rules that are difficult to enforce, said George Seaver, a vice president of Waldoboro firm Ocean Organics, who has been involved in processing rockweed for 40 years. Rockweed is harvested from tidal mudflats where property boundaries can be ill-defined, he said.

Seaweed matters: Eat your vegetables

April 26, 2019 — When I sat down at a Portland kombucha bar to attend a local Seaweed 101 session, I fully expected a love story about wild, vegan kelp and how we can change the world by eating more sea vegetables. What I didn’t expect was an in-depth exchange about federal fishery management and how it has decimated the industry’s communities in New England.

VitaminSea owner, and host of the session, Tom Roth was a commercial tilefish captain out of New Jersey a lifetime ago. He transitioned into New York Harbor tugboats as the industry declined, and started diving for kelp in his spare time from his home base in southern Maine about 15 years ago.

These days he goes out in a 40-foot boat that carries three other divers, two wooden skiffs and two Zodiacs. Each diver takes a small craft out on his own; they spread out, harvest, then meet back at the boat to help each other unload.

Aquaculture Rule Changes up for Public Comment in Maine

January 14, 2019 — Maine fisheries managers are looking to make a number of changes to aquaculture rules in the state, and are asking for feedback from the industry and the public about the potential changes.

The Maine Department of Marine Resources is considering a proposal that would make changes to the leasing procedures it uses for farmers of seafood. The new rules would also clarify that an emergency lease could be used when the safety of consumers is threatened, and they would establish minimum lease maintenance standards.

Why some Maine coastal communities are up in arms about aquaculture

December 10, 2018 — From oyster farms to cultivated seaweed and farm-raised salmon, aquaculture is often described as essential to the economic future of Maine’s fisheries in the face of a changing ecosystem. Warming waters from climate change are pushing lobster farther Down East and have shut down the shrimp fishery, and threats such as ocean acidification and invasive green crabs are harming Maine’s natural fisheries.

But opposition to several proposed projects suggests the hardest part of getting into aquaculture might be getting past the neighbors. All along the coast, neighbors argue that pending aquaculture ventures will create too much noise, use too much energy, attract too many birds and obstruct their opportunities for boating or lobstering. One questioned whether an oyster farm would make it hard for deer to swim from one point of land to another.

In Belfast, abutters to the land where Nordic Aquafarms hopes to put in a giant land-based farm to raise salmon have filed a lawsuit against the city, which they say hastily and secretly approved a zoning change the company needed to move forward.

In Brunswick, opponents of a proposed 40-acre oyster farm have hired not just attorneys, but a public relations expert, Crystal Canney, in the hopes of persuading the Department of Marine Resources not to approve the lease.
