MAINE: Maine seeks new ESA tools to speed Atlantic salmon recovery

July 16, 2026 — The Maine Department of Marine Resources (DMR) is asking federal fisheries officials to evaluate whether existing authorities under the Endangered Species Act (ESA) could help accelerate Atlantic salmon recovery while maintaining current protections.

In a June 4 letter to the National Marine Fisheries Service, DMR Commissioner Carl Wilson requested that NOAA review whether the ESA could provide additional flexibility to expand Atlantic salmon recovery efforts. The Bangor Daily News reported that the request could eventually create opportunities for tightly controlled, conservation-oriented catch-and-release fishing if the species recovers.

The request follows decades of habitat restoration, fish passage improvements and river connectivity projects that have benefited Atlantic salmon and other sea-run fish. However, Sean Ledwin, director of the DMR Bureau of Sea Run Fisheries and Habitat, said adult Atlantic salmon returns remain very low despite those investments.

MAINE: Maine is exploring a path that could bring back Atlantic salmon fishing

July 13, 2026 — The Maine Department of Marine Resources is asking a federal agency to review whether existing endangered species laws could provide new tools to accelerate Atlantic salmon recovery, an effort the state says could eventually create opportunities for tightly controlled catch-and-release fishing if the species recovers.

In a June 4 letter to the National Marine Fisheries Service, DMR Commissioner Carl Wilson asked the National Oceanic and Atmospheric Administration to evaluate whether authorities under the Endangered Species Act could provide additional flexibility to expand Atlantic salmon recovery efforts while maintaining existing federal protections.

The request comes after decades of habitat restoration, improved fish passage and river connectivity projects that have benefited Atlantic salmon and other sea-run fish, but adult Atlantic salmon returns remain very low despite those investments, according to Sean Ledwin, director of DMR’s Bureau of Sea Run Fisheries and Habitat.

Cocaine Pollution Seems to Make Salmon Swim Farther Than Usual. Scientists Don’t Know the Long-Term Consequences

April 24, 2026 — The world’s waterways are becoming increasingly contaminated with pharmaceuticals and illegal drugs—and the pollutants are seeping into marine animals. Cocaine, specifically, has been found in sharks, shrimp, mussels and eels, but exactly how these human-derived contaminants might be affecting wildlife has remained mysterious.

Now, new research offers a first look at how cocaine can alter the behavior of fish in the wild. Young Atlantic salmon exposed to cocaine’s primary metabolite—the compound created when human bodies break down the drug, which gets excreted into wastewater—swam farther than their sober peers in a Swedish lake, researchers report in a study published April 20 in the journal Current Biology.

The findings affirm the need to “carefully understand and manage all of the diverse chemicals society uses that can end up in our waterways,” Mark Servos, an ecotoxicologist at the University of Waterloo in Canada who was not involved with the research, tells Science’s Erik Stokstad.

The scientists behind the new study visited an Atlantic salmon hatchery in southern Sweden, where they outfitted 105 two-year-old, captive-raised fish with tracking tags and slow-release capsule implants. In one-third of the group, the implants gradually released cocaine into the creatures’ bodies. In another third, the devices released cocaine’s main metabolite, benzoylecgonine. In the final third—the control group—the implants provided no chemical related to the drug.

MAINE: The Fragile Hope for Salmon Recovery in Maine

March 30, 2026 — On a bright March morning, Paul Christman hiked through deep snowdrifts on the bank of Avon Valley Brook in the western Maine mountains, leading a crew wearing waders and shouldering unwieldy backpacks.

One crew member carried a pack basket loaded with battered funnels crafted from stovepipes, duct tape and plumbing pipes. Another lugged a water pump. The last brought a cooler full of thousands of fertilized Atlantic salmon eggs.

The stream was mostly iced over, but Mr. Christman, a marine scientist with the Maine Department of Marine Resources, found some open water on the brook, a tributary to the Sandy River.

“This is a really good spot,” Mr. Christman said. “The river is picking up velocity and shoving that water into the gravel, so we’re going to set up right here and do it.”

For 20 years, Mr. Christman has been working to restore salmon to this Sandy River watershed, where they were eradicated after dams built in the 1800s blocked their passage.

The strategy is producing thousands of juvenile salmon that migrate to the North Atlantic, but just a handful that return to Maine to spawn as adults.

Now, a $300 million project to remove or modify four dams downstream on the Kennebec River is infusing the work with new hope, possibly clearing the way for salmon to swim freely up to the Sandy River within a decade.

Hundreds of thousands of Atlantic salmon once flooded rivers in New England. For millenniums, the fish have been valued by Native Americans in the region as sustenance and cultural touchstones.

But marine survival rates for Atlantic salmon have plummeted over the last 35 years, for reasons that are complex and interwoven, including changing prey, shifting currents and warming waters.

More recently, they’ve been regarded by anglers as the “king of fish.” But by 2000, their numbers had fallen so low that federal regulators listed them for protection under the Endangered Species Act.

Early recovery efforts focused on the last remaining populations of Atlantic salmon in the United States, all in Maine, in the Penobscot River, and the Mid-coast and Down East regions.

MAINE: Great Northern Salmon announces multiple strategic partnerships for Maine-based salmon RAS

March 3, 2026 — Great Northern Salmon announced multiple strategic partnerships with companies as it continues to work on its Millinocket, Maine, U.S.A-based salmon recirculating aquaculture system (RAS) facility.

Great Northern Salmon (GNS), formerly known as Katahdin Salmon, had already announced a strategic partnership with Eyvi, a provider of aquaculture systems. Now, the company said it has established partnerships with other aquaculture technology providers, engineering and construction companies, and potential buyers for its product once it gets its facility online.’

Expert panel predicts salmon supply could be tight in 2026

January 21, 2026 — A panel of salmon industry experts at the Global Seafood Market Conference in Hollywood, Florida, U.S.A., are predicting supplies of farmed salmon could be constrained due to relatively flat production.

Salmon supplies in 2025 were marked by an increase in volume out of Norway, with data shared during the panel indicating the Norwegian Atlantic salmon harvest increased by roughly 11 percent in 2025.

Fisheries management and Greenland

September 9, 2025 — Greenland has been much in the news since the Trump administration announced its desire to control the world’s largest island. While geographically part of North America (as is western Iceland), Greenland is a semi-autonomous region under the control of Denmark and is politically and economically aligned with the European Union. The EU pays Greenland over $20 million annually for access and support of Greenland’s fisheries.

While seafood products including halibut, shrimp, and mackerel account for well over 90 percent of Greenland’s exports, Greenland seldom makes the fisheries news in North America. Yet several North American stocks migrate to Greenland waters, most notably Atlantic salmon and bluefin tuna.

Bluefin tuna have been reported as bycatch in the Greenland mackerel fishery, and Atlantic salmon from Maine and Canada can be caught in the island’s subsistence salmon fishery. Salmon bycatch in Greenland’s commercial fisheries is deemed insignificant.

MAINE: Maine Sea Grant helping state conserve Atlantic salmon

July 15, 2025 — Whether it’s through fish stocking, habitat restoration or research, the University of Maine-led Maine Sea Grant is helping the Maine Department of Marine Resources (DMR) conserve Atlantic salmon in the Gulf of Maine — the last wild populations of the species in the U.S.

Through a program offered by Maine Sea Grant and NOAA Fisheries that is now in its sixth year, paid summer interns have been working with the department on Atlantic salmon research and conservation for 13 weeks each summer — from Downeast Maine to the Kennebec and Penobscot River watersheds. They conduct field and lab work to support this endangered species and other sea-run fishes.

“The Maine Sea Grant internship program not only supports the restoration of sea-run fish like Atlantic salmon but also fosters a two-way exchange of knowledge with the department,” said Sean Ledwin, the director of DMR’s Bureau of Sea-Run Fisheries and Habitat. “The interns learn firsthand from experienced professionals in the field, while bringing fresh energy, new ideas and capacity to vital restoration efforts. This collaboration strengthens conservation outcomes and builds the next generation of marine scientists and stewards.”

“This program emphasizes collaborations and partnerships that expose students to different career paths to help conserve vital species and support Maine ecosystems, economies and cultures,” said Julia Hiltonsmith, a UMaine Sea Grant graduate assistant who mentors sea-run fish interns. “Guiding these interns through their fieldwork has not only deepened my appreciation for the dedication they’ve brought to conservation but also reinforced the importance of fostering collaboration and professional growth in the next generation of marine scientists.”

Since the Sea-Run Fish Internship Program launched in 2020, 12 students from UMaine and its regional campus, the University of Maine at Machias, have participated and conducted research and conservation work statewide for DMR, the United States Geological Survey, the Maine Department of Environmental Protection and the Penobscot Nation. Black Bear students, as well as participants from other universities, have gained hands-on learning experiences and professional development in science communication, which prepare them for in-demand careers in marine sciences and conservation.

A Sign Your Fish Might Be on Drugs: Risky Behavior

April 11, 2025 — It has to be stressful: an obstacle course of giant dams, rushing rapids and hungry predators.

That’s what juvenile salmon can face when they migrate out to the salty sea from the freshwater rivers and streams where they hatched. But it turns out that a very specific kind of pollution might be giving some fish an edge, at least on part of the journey.

According to a new study published on Thursday in the journal Science, young salmon exposed to anti-anxiety drugs in the water made it past dams faster. But ecologists are doubtful that it means a survival advantage.

Pharmaceutical pollution is rampant. Nearly 1,000 drugs and their byproducts have been detected in the world’s waterways, including in surprising places like Antarctica. They enter the environment as direct pollution from drug producers, from people flushing unused medications, and from human and animal waste.

Scientists have been studying the effects of these drugs on wildlife for years, but there is still much to learn about how animals respond to the “cocktail of different pharmaceuticals” they’re exposed to, said Michael G. Bertram, a behavioral ecologist at the Swedish University of Agricultural Sciences and a leader of the new study.
