EU, Greenland ink new fisheries partnership agreement

January 11, 2021 — Negotiations have concluded for a new sustainable fisheries partnership agreement (SFPA) and protocol between the European Union and Greenland that will strengthen their cooperation in the fisheries sector for the next four years, with the possibility of a two-year extension.

According to the European Commission, the agreement is “a new important milestone” in the long-standing bilateral cooperation between the E.U. and Greenland on fisheries issues, and renews their commitment in promoting a sustainable use of marine resources.

Narlugas Are Real

June 20, 2019 — In the late 1980s, an Inuit subsistence hunter named Jens Larsen killed a trio of very strange whales off the western coast of Greenland.

He and his fellow subsistence hunters would regularly catch two species: narwhals, whose males famously have long, helical tusks protruding from their snouts; and belugas, with their distinctive white skin. But Larsen’s new kills were neither. Their skin wasn’t white, nor mottled like a narwhal’s, but uniformly grey. The flippers were beluga-like, but the tails were narwhal-esque. In all his years of hunting, Larsen had never seen anything like them. He was so struck that he kept one of their skulls on the roof of his toolshed.

In 1990, it caught the attention of Mads Peter Heide-Jørgensen, a scientist who studies marine mammals. With Larsen’s permission, he took it to the Greenland Fisheries Research Institute in Copenhagen for study. And after comparing it to the skulls of known belugas and narwhals, he suggested that it might have been a hybrid between the two species—a narluga.

It was a reasonable idea. Belugas and narwhals are the same size, share the same Arctic waters, and are more closely related to each other than to any other species. Individuals from both species have been found swimming among each other’s pods. But no one had ever found a narluga before, and at the time, Heide-Jørgensen had no way of confirming his hypothesis.

US, Russia, China, others to sign agreement preventing illegal fishing in Arctic

October 3, 2018 — The United States is set to join nine other countries and organizations in a first-of-its kind agreement to protect Arctic Ocean waters from commercial fishing.

The pact, scheduled to be signed Wednesday, 3 October in Ilslissat, Greenland, comes after two years of negotiations between countries with coastlines on the Arctic as well as other major fishing powers. Those nations concluded talks last November.

The agreement comes as polar melting has reduced the Arctic ice cap and open new areas in the central part of the ocean for vessels. That means commercial fishing may be viable in those areas.

However, nine years ago, the U.S. closed its exclusive economic zone in the Arctic off the northern Alaskan coast to commercial fishing operations until government officials learned more about the region’s ecosystem. Alaska fishermen have expressed fears that the melting could lead to foreign vessels fishing in U.S. waters.

In a statement released 1 October, the U.S. State Department said the Greenland agreement cuts down chances of illegal fishing taking place in U.S. waters currently off limits to American fishermen.

Under terms of the agreement, the participating nations must create plan to study the Arctic’s ecosystem and not just for fishing purposes.

Michael Byers, an international law professor at the University of British Columbia, praised the countries for their forward thinking on the matter in a Canadian Press article.

Melting ice poses fleeting ecological advantage but sustained global threat, Stanford scientist says

August 31, 2018 — From collecting field samples inside the ocean’s frozen ice pack to analyzing satellite images in the comfort of his Stanford office, Kevin Arrigo has been trying to figure out how the world’s rapidly thinning ice impacts polar food chains. Arrigo, a professor of Earth system science at Stanford School of Earth, Energy & Environmental Sciences, found that while melting ice threatens to amplify environmental issues globally, ice sheet retreat can provide much-needed food in local ecosystems.

Through this work, Arrigo discovered that thinning ice at the poles can alleviate polar food deserts by extending phytoplankton blooms. However, the silver lining associated with melting ice cannot make up for imminent threats, such as rising sea levels, associated with unchecked glacial shrinkage.

Arrigo, who is also the Donald and Donald M. Steel Professor in Earth Sciences, spoke with Stanford Report about his work on polar phytoplankton blooms and discussed whether recent news about sea ice breaking up suggests we’ve reached a tipping point.

What have you learned about how glacial melt impacts food chains in the extreme environments of the poles?

It turns out that when glaciers form, they accumulate particles and dust that contain essential nutrients like iron, on which all living things depend for survival. As glaciers melt, they add nutrients to the ocean and fertilize the local ecosystem. In Greenland and Antarctica, the ocean is short on iron, so melting glaciers make up for the lack of iron.

Greenland Salmon Agreement Touted as Path to Save Fish

June 21, 2018 — Conservation groups say they are optimistic that an agreement with Greenland will help endangered wild Atlantic salmon begin to recover.

The salmon are considered endangered in the Gulf of Maine by the U.S. government. The North Atlantic Salmon Conservation Organization held a meeting in Portland last week to try to broker a deal to keep more of the fish alive.

Greenland fishermen continue to fish for the salmon, while U.S. commercial fishermen do not. The NASCO meeting resulted in a deal in which Greenland will reduce its annual quota for the fish from nearly 100,000 pounds to about 66,000 pounds. It also suspends Greenland’s commercial harvest of the fish.

Conservation groups’ pact will help save Atlantic salmon

May 30, 2018 — PORTLAND, Maine — Two conservation groups said Tuesday a deal has been struck with commercial fishermen in Greenland and the Faroe Islands that will help thousands of vulnerable Atlantic salmon return to rivers in the United States, Canada and Europe.

Commercial fishing for Atlantic salmon is prohibited in the United States, where the fish’s Gulf of Maine population is listed under the Endangered Species Act. But the Atlantic Salmon Federation and North Atlantic Salmon Fund said their new deal with Greenland and Faroe Island fishers is a major step toward recovery because it will dramatically reduce fishing.

Coastal Greenland and the waters off the Faroe Islands are important feeding grounds for salmon. Fishermen who work those waters take fish that originate in both jeopardized populations in Maine and New Brunswick, Canada, and healthy populations elsewhere.

The agreement places new limits on fishing, including ending the Faroe Islands fishery.

Here’s a look at the agreement and the status of Atlantic salmon in the United States and Canada:

Economic impacts of climate change on global fisheries could be worse than we thought

October 17, 2016 — Marine fisheries have been estimated to support the livelihoods of 10 to 12 percent of the world’s population and generate an average of $100 billion in revenue every year. But global fisheries are facing a number of challenges: changes in markets, demographics, and over-exploitation will significantly impact global fisheries in the near future, while climate change is expected to pose a major challenge over the longer term.

A study published last month in the journal Scientific Reports explores the potential economic impacts of climate change as it affects the amount and composition of fish in marine fisheries and leads to decreased catches. Previous research has shown that global warming will cause changes in ocean temperatures, sea ice extent, salinity, and oxygen levels, among other impacts, that are likely to lead to significant shifts in the distribution range and productivity of marine species, the study notes.

“Warmer temperatures may also lead to decreases in maximum body sizes of marine fishes,” write the authors of the study, a team of scientists from the University of British Columbia (UBC). These changes will be regionally specific, as predicted species distributional shifts and changes in ocean productivity due to climate change are expected to result in increases in maximum catch potential in high latitudinal regions but decreases in the tropics. The researchers add that “These changes have large implications for people who depend on fish for food and income, and thus the contribution of fisheries to the global economy.”

In all, the UBC researchers found that global fisheries could lose approximately $10 billion in annual revenue by 2050 if climate change continues unchecked — a 10 percent decrease, which is 35 percent more than has been previously estimated.

Countries that are most dependent on fisheries to feed their populations will experience the biggest impacts, according to the study. The largest average decrease in maximum catch potential will occur in small island countries like Tuvalu, which is expected to see a 79 percent drop in annual catches in its waters, and Kiribati, which is projected to see a 70 percent decrease.

“Developing countries most dependent on fisheries for food and revenue will be hardest hit,” Vicky Lam, a postdoctoral fellow at UBC’s Institute for the Oceans and Fisheries and the study’s lead author, said in a statement. “It is necessary to implement better marine resource management plans to increase stock resilience to climate change.”

On the other hand, some developed countries, such as Greenland and Iceland, could see revenue increases as fish move into cooler waters.

Ocean Warming Is Already Affecting Arctic Fish And Birds

September 13, 2016 — Up until a few years ago, mackerel were unknown in Greenland’s cold waters. The small oily fish typically spawned west of the British Isles and then migrated toward the northeast along the Norwegian current to feed for the summer. But in 2007, they began to show up in large numbers in the Irminger Current around Iceland. On the ocean highway, where they once turned right, they now turned left.

By 2011, the mackerel had found their way into Greenlandic waters, prompting the launch of a new fishery. Three years later, the mackerel fishery made up 23 percent of Greenland’s export earning, an “extreme example of how climate change can impact the economy of an entire nation,” Teunis Jansen, a researcher at the Technical University of Denmark, said in a release.

The mackerel aren’t the only species being affected by warmer oceans. Soaring temperatures have pushed entire groups of species toward the poles, caused increases in disease in plants and animals and changed weather patterns, according to a report launched this week by the International Union for Conservation of Nature (IUCN). Marine species are moving northward at a rate roughly five times faster than the migration of land animals.

The report, released during the IUCN World Conservation Congress in Hawaii, highlights the impacts of ocean warming on marine life, from microorganisms to mammals. Eighty scientists from a dozen countries worked on the report, considered to be the most comprehensive collection of research on the planet’s warming oceans.

Truly Staggering

“We were astounded by the scale and extent of ocean warming effects on entire ecosystems made clear by this report,” said Dan Laffoley, an IUCN marine adviser and one of the report’s lead authors.

The world’s oceans have acted as a buffer against climate change. A “staggering 93 percent” of the heat produced by human activities has been absorbed by the world’s oceans, Laffoley said. If the heat had entered the atmosphere instead of the oceans, the Earth would have warmed not by the 1C (1.8F) we have already experienced, but by 36C (64.8F). “Up to now, the ocean has shielded us from the worst impacts of climate change,” the report’s authors write.

Scientists, fishermen plot ways to prevent whale entanglements

May 25, 2016 — PORTSMOUTH, N.H. — Nette Leverman was reading from a sheaf of papers she held in her hand, detailing the interactions between whales and fishermen in Greenland, where she is a population biologist.

Humpback, minke, fin and bowhead whales were getting caught in fishing line and nets in the waters off the country’s coast. It’s a familiar refrain, heard over and over Monday, the first day of a four-day international workshop on large whale entanglements.

“We’ve known for decades about this problem, yet solutions to it remain elusive,” said Tim Werner, a senior scientist at the New England Aquarium, and one of the workshop’s organizers.

Governments and fishermen around the world are feeling the strain from an increasing numbers of whales being snared in fishing gear as some whale species rebound and as the amount of gear in the water increases for fishing, aquaculture and other uses.

Saving Atlantic salmon will require Greenland’s help

March 13, 2016 (AP) — Preventing the long-imperiled Atlantic salmon from disappearing from American waters will require the U.S. to put pressure on Inuit fishermen in Greenland to stop harvesting a fish that has fed them for hundreds of years, federal officials say.

The salmon were once found from Long Island Sound to Canada, but their population has cratered in the face of river damming, warming ocean waters, competition for food with non-native fish and, officials say, continued Greenlandic fishing.

Now, federal officials have outlined an ambitious plan to try to save the Atlantic salmon that they say will require removing dams, creating fish passages and fostering cooperation with Inuit fishermen some 2,000 miles away from Maine, where most of America’s last wild Atlantic salmon spawn.

“We’ve tried everything possible to negotiate with Greenland to find alternatives to find out how they can lessen impacts on U.S. fish,” said Dan Kircheis, a fisheries biologist with the National Marine Fisheries Service. “This is part of their culture, this is part of who they are, this is something they’ve always done. We are trying to work with them to realize the fish they are fishing for originate in Canada, in U.S. waters, in Europe, and these populations are in decline.”
