MAINE: Lobsters remain plentiful in Maine, but outside forces cast uncertainty on industry

September 1, 2026 — There was a time when lobsters were so abundant along the Maine coast that they could be plucked by hand from shallow water. Those days are long gone, but for most people — whose interactions with lobsters happen on plates and rolls — it might be hard to say how lobsters and the lobster industry are doing. Lobster rolls might cost more, like everything else, but they’re still available.

Lobstermen are at the mercy of a range of outside forces: economic, ecological, regulatory. Trends in the lobster harvest and its value suggest lobstering is in a healthy position right now. But zooming out to include factors such as global trade and climate change show there is much uncertainty.

In the long view, the number of lobsters coming across wharfs is way up. From 1950 until the end of the 1980s, Maine lobstermen were landing around 20 million pounds of lobster each year. Some years the amount deviated, as low as 16 million and as high as 24 million, but the catch looks pretty consistent through those four decades.

MAINE: What’s the biggest threat to the lobster industry?

September 1, 2026 — Lobstermen are under threat. They all agree on that much. The threats they describe vary from one to the next. But they are worried about their future, and the future of a livelihood that many learned from their fathers and grandfathers and want to pass to their children and grandchildren.

The risks are larger than any one lobsterman — or even the industry as a whole. Lobstering “is not only an economic driver of coastal and island communities, it is an identity of our communities,” said Kristin Garabedian, a community development officer with the Island Institute’s Center for the Marine Economy. In other words, losing lobstering would make a town like Harpswell less like Harpswell.

Most lobstermen see the biggest threats coming from outsiders pursuing their own aims without regard for the lobstermen who live and work here. Those might be wind-power proponents, whale protectors, big businesses or homebuyers.

Few, if any, see climate change as an immediate or catastrophic threat, although they are deeply in tune with the changes happening in the Gulf of Maine and are worried about human impacts on the environment they depend on.

Climate change may halve omega‑3 fatty acids in fish and the organisms they eat

August 31, 2026 — You’ve probably heard eating fish and other seafood is good for your health. One of the main reasons is that seafood is an excellent source of two important omega-3 fats called EPA and DHA.

EPA and DHA are critical for the development and function of brains, eyes and healthy hearts. They also reduce chronic inflammation, which is linked to many chronic diseases. They can also reduce the risk of premature births and perhaps even some types of cancer.

While humans can produce EPA and DHA from ALA (an omega-3 fat found in plants) and it’s possible to get them from foods such as linseed and walnuts, seafood is the main source for most people.

However, our new study shows many fish and other seafood will become less rich in omega-3s over time, due to rising ocean temperatures as the climate changes. In fact, we found omega-3 could drop by 50% under very high warming scenarios.

This is very bad news for human health but also for the health of other animals in the food web.

‘We’re facing a double whammy’: America’s hottest tinned fish snack is shrinking by nearly half thanks to climate change and war in Iran

August 31, 2026 — Tinned fish is having a real global moment. The pandemic-era pantry habit has since turned into restaurants nationwide serving tinned fish straight out of the can. Domestically, sales climbed from $2.3 billion in 2018 to more than $2.7 billion in 2024, and the U.S.’s obsession with sardines specifically is only accelerating: Americans bought $3.52 billion worth of shelf-stable seafood over the past year, and sardines have overtaken salmon as the second-most-popular canned fish behind tuna, as Grubhub reported orders of tinned fish tripled in 2025. The global tinned fish market was worth roughly $10.24 billion in 2024 and is projected to reach $17.97 billion by 2034. Canned sardines are a meaningful part of that worldwide push.

But the supply behind that growing appetite is shrinking fast. Morocco, the world’s top sardine supplier, saw its fish landings fall nearly 46% between 2022 and 2024, and the reasons are feeding into each other. Because sardines are unusually sensitive to temperature, warming water as a result of climate change is pushing the fish into new territories farther away from fishermen.

The war in Iran, coupled with the effective shutdown of the Strait of Hormuz (through which one-fifth of the world’s global oil supply normally passes), is driving up fuel costs. Fishermen now need to go farther to catch the fish, just as it’s costing them that much more to travel longer distances, and they’re bringing back almost half the quantity as before.

Rashid Sumaila, a professor and Canada Research Chair in interdisciplinary ocean and fisheries economics at the University of British Columbia, has spent his career studying fisheries and how they navigate geopolitical forces. He said the combination is something he hadn’t seen affect the fishing industry in quite this way before.

“Sardines are very sensitive to climate change, and we know it here on the Pacific Coast,” Sumaila told Fortune. “When it’s warm, sardines move from Mexico through the U.S., and Canadians see more sardines. They follow the temperature.”

He said Morocco’s sardines are shifting, too, and he saw the same thing while on a trip to Portugal this summer, when he left his hotel at 2 a.m. for an early flight and the temperature was still 34°C (91°F).

“Some of that 45% drop is partly climate change, and partly overfishing, and other things happening to the ocean,” he said. “There’s just so much. You have pollution, plastic. Stresses upon stresses.”

The Iran war adds a second layer. While Iran’s own waters are not a major sardine source, Sumaila said the war still reaches Moroccan boats through the price of fuel.

“The Iran war doesn’t quite impact this directly,” he said, “but indirectly it does, because prices are going up. The price of fishing, the vessels, the energy. It’s crazy.”

Since the conflict began, Brent crude surged 10% to 13% after the Strait of Hormuz effectively closed to shipping this spring, an event the International Energy Agency called the largest oil-supply disruption in the market’s history. Sumaila said he heard the same complaint from fishermen thousands of miles from the Persian Gulf.

“Thai fishers are feeling it,” he said. “You can imagine Moroccan fishers, or fishers in Africa or the Pacific Islands, feeling it too.”

Beyond the salmon crisis: Northwest may face broad loss of freshwater species

August 27, 2026 — Using eDNA to map and save lower-profile species crucial to the ecosystem, researchers say

According to a recent Convention of Migratory Species Report, migratory freshwater fish populations have dropped 81% worldwide since 1970. While Northwest Washington species face many of the same pressures as other species across the planet, the story here is a bit more nuanced, and researchers point to a unique interagency collaboration in the state as a pathway forward.

Salish Sea Chinook salmon populations are down 60% since the Pacific Salmon Commission began tracking salmon abundance in 1984, according to the 2024 State of Salmon in Watersheds report.

Around the Salish Sea, Chinook salmon provide immense ecological, cultural and economic value. According to the report, Puget Sound was once home to larger populations of Chinook and other salmon, with a greater diversity of traits than populations existing today. Only 22 of at least 37 historic Chinook salmon populations remain in this ecosystem. The remaining Chinook salmon populations are at about 10% of their historic numbers. Between 2000 and 2018, the total number of Chinook returning to the Salish Sea has shown a relatively stable trend.

These salmon populations face the same pressures as freshwater fish listed in the global report: habitat loss, harvest rates and climate change.

“All the research, all the science, all the data that’s been analyzed shows us that habitat is by far the leading threat,” said Annitra Peck, executive director of the Nooksack Salmon Enhancement Association. “You’ve got hydropower, you’ve got harvest management, you’ve got these other pieces that have so much to do with it, and they all definitely intersect, but habitat is in large part the driving concern. Salmon are an anadromous species; they utilize freshwater and saltwater, they need to be able to travel back and forth in their unique life cycle, and if they don’t have the habitat to do that, then that falls apart. It prevents that life cycle from continuing and that reproduction for salmon to be able to replace themselves essentially.”

Earth is simmering in its hottest water temps on record, and that’s bad for fish and us

August 25, 2026 — The world’s oceans simmered to their hottest temperatures on record over the weekend and are likely to warm even further in the next few months, putting stress on life in the water and on land too, the European climate service Copernicus announced Monday.

Spurred by a still growing but already supersized natural El Nino and human-caused climate change, the world’s ocean temperatures hit 21.1 degrees Celsius (70 degrees Fahrenheit) on Friday and Saturday, narrowly edging out the average daily record set in March 2024, said Samantha Burgess, strategic climate lead for Copernicus.

“This is yet another sign of our climate system under strain and the ocean under immense pressure,” Burgess said.

Jane Lubchenco, an oceanographer and former chief of the U.S. National Oceanic and Atmospheric Administration called the record “very troubling.”

“An ocean this warm destabilizes weather patterns and threatens food security, economic prosperity and marine life,” Lubchenco said in an email. “A warmer ocean is not our friend.”

CALIFORNIA: California’s rarest salmon face a narrow window for survival

August 24, 2026 — For California’s most endangered salmon, the difference between surviving and dying may come down to just 15 days.

In a study published Friday in Science Advances, researchers say the chance of juveniles surviving fell by about 73% for every 1.8-degree Fahrenheit increase in average river temperature during those first 15 days.

Sacramento River winter-run Chinook have only one surviving population, with an average of a few thousand fish returning in recent decades.

Shasta Dam keeps the salmon from returning to their original cold-water habitat around Mount Shasta in Northern California. Instead, they spawn in the Sacramento River, where warmer summer water can threaten their developing eggs.

Cold water is released from Shasta Reservoir to keep the river cool enough for salmon eggs to survive, but that water is also needed by farms and cities.

The balance becomes harder in dry years, when there’s less water to go around.

Kohma Arai, who conducted the research as a postdoctoral scholar at UC Davis, said a full summer of spawning doesn’t necessarily mean a successful season.

How AI is reshaping ocean science

August 21, 2026 — Stark against the white Antarctic terrain, a small, yellow robot moves roughly one centimeter per second. Too fast, and it might spoil its mission: to gather data on a colony of emperor penguins that call the Southern Ocean home.

Artificial intelligence recognition tools help the robot, called ECHO, spot when the penguins start to get spooked. A green box over the penguin signals that it’s calm, but a red box signals stress.

To keep the boxes green, ECHO must approach very slowly, said Daniel Zitterbart, associate scientist with the Woods Hole Oceanographic Institution and the project lead on ECHO.

“The good thing is a robot doesn’t get bored,” he said.

AI tools are quietly transforming how ocean scientists gather and analyze information from the watery deep. Researchers from WHOI, the University of Rhode Island, and the UMass Dartmouth School of Marine Science and Technology (SMAST) have either employed AI tools for decades or are looking to incorporate the technology into future projects, exponentially increasing the volume of data they’re able to collect.

These new applications, often going hand in hand with work seeking to better understand climate change, come as the technology faces backlash from environmental advocates concerned about the amount of water and electricity necessary to sustain it.

In some ways, researchers say the technology is a boon in an era when scientists need to do more with less federal funding. But these researchers are also quick to point out that AI tools will never replace human scientists — and the public money that funds them.

“There is no AI that can help me go out in the field and catch a penguin,” Zitterbart said. “To learn about the natural world, you still need to go into the natural world.”

Lobsters and acidic seas: can shellfish help neutralise one of the greatest threats to the ocean?

August 21, 2026 — For many in the US region of New England, the lobster roll is synonymous with summertime. Loaded into a toasted bun, chunks of the sweet meat are served hot and soaked in butter, or chilled and slathered in mayonnaise with celery and herbs.

The only thing more debated than the recipe is the price: the once-humble roll now routinely fetches $30 (£22), or even $50, in a sign of the changing times – and seas.

A third-generation lobster fisherman, Scott Lord spends his days hauling traps on the Gulf of Maine, which is warming faster than 99% of the world’s oceans. “Whether you agree with who says why it’s happening, it is happening,” he says.

Bycatch that was once plentiful, such as sea urchins, sand dollars or starfish, are increasingly rare. And, most concerning, Lord has noticed the number of inshore lobsters dropping dramatically over the past 15 years, pushing fishers farther and farther offshore.

Motivated to find a remedy, Lord joined a regional shellfish committee. “Why are there not clams where there used to be clams? Why are they not coming back, no matter what we do?” he asks.

Hundreds of miles to the south in Massachusetts, on a sandy crook of land that spins out to form Cape Cod, Adam Subhas, a scientist at the Woods Hole Oceanographic Institution, is trying to find the answers.

ALASKA: ‘How do you buy time?’ Scientists look to slow an Alaska glacier’s march to the sea

August 21, 2026 — The Valerie Glacier is sliding toward the ocean, fast. Over the course of 18 days in July, the glacier galloped a whopping 150 feet— the length of four school buses parked end-to-end.

With it went a small research camp, made up of a cluster of tents pitched under jagged peaks. The scientists were there to study the Valerie and whether it might be possible to slow its disappearance into the sea.

As the team donned snowshoes and skis to head into the field, Melenda Lekanof, the project’s community liaison, took in the seemingly endless glaciated landscape. She said she was thinking about her ancestors – the Ginéix Kwáan or Kwáashk’ikwáan, of the Copper River region – migrating through here centuries ago.

“It’s breathtaking, and it’s a bit overwhelming, because this is part of who I am,” said Lekanof, who is from Yakutat and is Tlingit and Aleut.

But she’s also worried about the future. The world’s glaciers have lost about 5% of their ice since 2000 as temperatures rise with climate change. And Alaska’s glaciers are disappearing even more quickly.

“I don’t know if this is going to be here in my time,” Lekanof said. She added: “We need to know what’s going on.”
