Alaska and Canada have agreed to a seven-year moratorium on Yukon River chinook salmon fishing.

According to a release from the Alaska Department of Fish and Game, the in-river closure for one full king salmon life cycle is outlined in an agreement signed April 1 by the state agency and its Canadian counterpart. It halts the harvest of kings on the mainstem of the Yukon, as well as Canadian tributaries, in an attempt to recover the long-depressed stocks.

The agreement sets a 71,000 Canadian-origin chinook annual border passage target, and allows for consideration of limited subsistence harvest if the target is projected to be reached. It’s been seven years since that many kings crossed the border into Canada, and last year’s passage estimate was under 15,000.

Regardless of run size, the new agreement allows for consideration of limited chinook harvest for ceremonial and cultural purposes.

Another part of the agreement requires development of a Yukon River chinook salmon rebuilding plan.

First, the good news. When a 53-foot fish tanker truck crashed and rolled upside down on an embankment next to a creek in northeast Oregon, its driver suffered only minor injuries. And as the truck came to a rest, its tank settled downhill, next to the water.

That last detail was crucial for the truck’s cargo: some 102,000 spring chinook smolts, or young salmon, that had been raised in a hatchery. The truck overturned on a twisting road that mirrors Lookingglass Creek — and some 77,000 fish made it from the tanker into the creek’s fresh, inviting water, according to the Oregon Department of Fish and Wildlife.

But there is also bad news: 25,529 smolts died, recovered from the tanker and the bank of the creek. And the fish that survived are now living in the wrong waterway.

The fish had been raised at Lookingglass Hatchery to give a population boost to wild salmon in the Imnaha River, around 90 miles to the east.

“The smolts lost represent about 20 percent of the total that will be released into the Imnaha River this year,” the Oregon Department of Fish and Wildlife said.

The smolts — the term for young salmon that are old enough to transition from freshwater to the salty ocean — had been on the cusp of freedom, ready for release in the hopes that hundreds of them would migrate to the Pacific and back to spawn.

Instead of the Imnaha River, the smolts are in Lookingglass Creek, a tributary of the Grande Ronde River. And for those that survive long enough to spawn, the creek is now the destination they’ll punch into their piscine GPS system.

“Fishery managers expect to see about 500-900 fewer adult fish returning in 2026 and 2027 due to the loss,” Oregon’s wildlife agency said. “The 77,000 fish that made it into Lookingglass Creek will likely return there and produce approximately 350-700 additional adults.”

Both the Imnaha and Grande Ronde are tributaries of the Snake River, which in turn feeds into the Columbia River and, finally, the ocean.

The spring chinook salmon is federally listed as a threatened species in the Snake River, including the fish’s important origin locations such as the Grande Ronde and Imnaha rivers.

The hatchery program is part of a plan to mitigate challenges to the salmon population posed by hydropower projects, according to the Oregon Department of Fish and Wildlife. For decades, the Nez Perce Tribe and the Confederated Tribes of the Umatilla Indian Reservation have been working to return salmon to Lookingglass Creek and other habitats in the area, looking to restore historic cycles of animal life and human tradition.

For State Historian and Deputy State Historic Preservation Officer Katie Ringsmuth, Alaska is linked to maritime history – a history dating back thousands of years to when Asia and North America were connected by Beringia.

“So much of Alaska history really is under the umbrella of maritime history,” she said.

The Alaska Maritime Heritage Preservation Program from the state’s Department of Natural Resources is seeking to preserve some of that history. Ringsmuth said the program received federal funds and is now regranting those funds to communities across the state.

“This program helps to preserve maritime resources, whether it’s buildings or whether it’s more educational [activites],” Ringsmuth said. “Really, it’s about helping to remind the rest of the country how important Alaska is in defining its maritime north.”

In total, the program is funding fifteen projects with the grant money. It aims to have most of the projects complete by June of 2025. The program’s website states that these projects were chosen based on grant criteria from the National Park Service.

$48,000 will go toward two projects in Bristol Bay. The region has nearly 140 years of commercial fishing history.

The larger of the two grants, totaling $38,000, will support sailing a restored double-ender sailboat from Naknek to Dillingham. This funding is split between the Bristol Bay Heritage Land Trust — a conservation group — and the Bristol Bay Historical Society.

Tim Troll, the Heritage Land Trust’s executive director said the grant funds phase two of the sailboat’s journey. In 2022, the organizations restored the boat and a crew sailed it from Homer to Naknek to commemorate the end of the commercial fishery’s sailboat days. Until 1951, the fishery only allowed sailboats. With the introduction of engine- powered boats however, Troll said that the double enders were quickly retired.

“We’d also like to take [the boat] over to Dillingham which is where the Bristol Bay commercial fishery got started in the Nushagak Bay back in 1884. So that seems appropriate to get the boat over there so people can see it and get in it and sail with it,” he said.

Troll said the aim is to get the boat on its journey to Dillingham by this summer. It takes roughly a day’s journey to sail there, he said, depending on the winds and tides.

The Bristol Bay Heritage Land Trust won the smaller grant, $10,000, as well. The money will fund a project to compile and digitize a historic account from Axel Widerstrom who took photographs as he traveled from San Francisco to Bristol Bay on his father’s ship.

“He was a young man in 1919. His father was the captain of the Star of France, one of the great Star [Fleet] ships [of the Alaska Packers’ Association], and he had a camera with him,” Troll said.

Troll said that Widerstrom completed taped interviews in 1976 that ended up in the National Maritime Museum in San Francisco. The tapes are gone, he said, but the grant money will give the opportunity to travel to California to collect the transcripts and photographs and to digitize them.

Troll said he thinks creating a record is relevant, as many families in the region have ancestors who came up on ships like the Star of France.

State Historian Katie Ringsmuth said she thinks it’s important to keep providing communities with the funds they need to protect their maritime history.

“This allows at least some money to go into communities so they can help preserve those resources, study them and interpret them and share them with the rest of the public,” she said.

She said she hopes the success of this year’s projects will lead to more grants that the program can distribute, so communities can continue to preserve their maritime heritage – from Indigenous technology to historic canneries.

The federal government has won a permanent injunction against the state of Alaska in a case important to subsistence fishing rights.

U.S. District Court Judge Sharon Gleason ruled Friday that state fisheries managers can’t allow salmon fishing on a long stretch of the Kuskokwim River if their orders conflict with federal management decisions aimed at protecting fish for subsistence use.

The dispute arose in 2021, a drastically low chinook salmon year. The Federal Subsistence Board and other federal officials sharply curtailed salmon fishing on 180 miles of the Kuskokwim, where it winds through the Yukon Kuskokwim Delta National Wildlife Refuge. They closed that section of river to non-subsistence harvests. They also limited subsistence fishing to local rural residents and imposed restrictions on when they could fish and what gear they could use.

The state Department of Fish and Game issued an order allowing all Alaskans — not just federally qualified subsistence users — to engage in the limited harvest.

Nearly the same conflict arose again in 2022. The federal government, the Kuskokwim River Inter-Tribal Fish Commission and the Alaska Federation of Natives, among others sued, asserting the subsistence fishing rights Congress established in a 1980 law. The case is called United States of America v. State of Alaska.

Judge Gleason issued a temporary injunction in 2022 blocking the state from issuing conflicting orders. Friday she made it permanent. The state’s conflicting fishing orders would hamper the U.S. government from enforcing the federal law protecting subsistence rights, she ruled, and federal law trumps state regulations.

The state maintains it has authority over fishing on Alaska rivers, even where they flow through federal refuges. It says the Alaska Constitution requires it to manage fish for the benefit of all Alaskans.

If past subsistence cases are any guide, the state will appeal. Subsistence advocates have won a series of cases against the state that went as high as the U.S. Supreme Court.

Scientists have many ways to track fish populations – but they usually require seeing the fish. Now, researchers at the National Oceanic and Atmospheric Administration are refining a method to collect data about what fish were present in an area — up to two days after those fish have moved on.

Diana Baetscher is a research geneticist at NOAA’s Alaska Fisheries Science Center in Juneau.  She said that when fish swim, they shed scales, slime, and other tiny fragments into the water. Those fragments contain DNA – and they can provide a breadcrumb trail for scientists looking to learn about fish populations.

“eDNA is environmental DNA,” Baetscher said. “It’s sort of a really simple concept. At its heart, it’s the fact that all organisms shed DNA or genetic material into the environment, and that can be water or air or soil.”

Baetscher said collecting environmental DNA is less time-intensive than some other methods. Scientists can scoop up seawater and test it to get a picture of what species of fish have recently passed through.

“eDNA has sort of grown as this way of trying to shortcut some of the amount of time that goes into those other ways of counting fish,” she said.

Baetscher is the author of a paper published on March 12 that will help scientists better interpret the data in those scoops of seawater. She says that while the signs can stay in the water for up to 48 hours after fish leave an area, that signal might be affected by factors such as tide and water temperature.

“So you know, if you have a really strong current downstream of a whole bunch of fish, do you see that signal changing because the current is changing, or the wind is changing, or the tide is changing? So, you know, we actually need to study the movement of the eDNA separate from the fish to be able to then use that to understand something about fish.”

Baetscher looked to net pens full of hatchery chum salmon in Juneau’s Amalga Harbor for a dense, consistent source of eDNA. She found that the signal left by the chum salmon was strongest at the water’s surface, and it disappeared faster during outgoing tides. Baetscher said this study was just one step towards making eDNA a more useful tool. In the meantime, eDNA is already being used to expand where scientists can track fish — like for Arctic fish communities under sea ice.

“Another that we’re really excited about is looking at changing species distributions in the subarctic and the Arctic,” she said. “What do those fish communities look like, and how much are they changing year over year and throughout a calendar year?”

Baetscher hopes the data collected by filtering water under the sea ice will give researchers a snapshot of fish communities that they otherwise would be unable to access.

Writers Olivia Ebertz and Bathsheba Demuth boated more than 1,000 miles up and down the Yukon River last summer, hearing the stories and perspective of residents and tribal leaders along the way.

ALONG THE YUKON RIVER — The midsummer air is hot after a long day of sun and stillness in the middle river village of Grayling, and the cutbanks seem to slouch closer toward the Yukon River below. Rachel Freireich says her mother moved here permanently from the Athabaskan village of Holikachuk, up a nearby tributary, in the 1960s to be closer to schools and salmon eddies.

“They came over with steamboats every summer to fish the salmon,” said Freireich, a resident of Grayling her entire 43 years.

In summers while she was growing up, Freireich says the village was a ghost town.

“The whole community would become kind of abandoned, because everybody would bring their whole families out and they went to the fish camp. Everybody was busy,” she said.

But in the summer of 2023, fish camps are empty. The few boats in the lower river are mostly in a search party looking for a missing person. From the mouth of the Yukon at the Bering Sea to the river’s headwaters in Canada, no one is fishing — the consequence of the second-lowest king salmon run on record. The worst was just a year prior, a grim milestone in the wake of decades of ebbing runs that have robbed Indigenous residents of both traditions and nourishment.

“After they cut off fishing, there was lack of work, lack of jobs, people in poverty. People really struggled. And we continue to struggle,” said Freireich.

Amid these devastating numbers, American and Canadian regulators are poised to sign a new international agreement they hope will help rebuild Yukon king stocks and reverse years of cultural and ecological damage. The agreement contains a weighty request: that all Yukon River subsistence harvesters cease fishing for a full seven-year life cycle of king salmon, also called chinook. This new burden would follow tight restrictions on subsistence fishing in the U.S. since 2008, and total closures since 2021.

In Canada, where First Nations set many of their own fishing restrictions, some communities have kept their chinook nets out of the water since the turn of the 21st century.

In January, the Alaska Department of Fish and Game and the Canadian Department of Fisheries and Oceans soft-launched the new draft agreement. Their goal is to get 71,000 chinook across the border. It’s been seven years since that many chinook swam into Canada; last year, managers estimated the number was about 15,000.

It’s an ambitious target, one that has to contend with a host of complexities. In Alaska, where the state is the primary manager of Yukon salmon, some tribal leaders are so frustrated by their exclusion from decision-making that they’re requesting federal oversight of fishing on the river. There are also fears that the agreement will open the door to hatcheries. And then there’s the greatest challenge migrating salmon face: the ocean. As they grow at sea, Yukon River chinook must eat enough to propel themselves as far as 2,000 miles up the longest salmon spawning river in the world — while facing predators, trawlers, and rapidly warming waters.

Cooperative management of the Yukon by the U.S. and Canada was borne from a dramatic chinook crisis in the late 1990s.

In 2001, the two countries formally signed the Yukon River Agreement, an annex to the 1985 Pacific Salmon Treaty. It requires the harvest to be equitable on both sides of the border, and that a “minimum sustainable escapement” of fish reach Canadian spawning grounds each season. The agreement also created the Yukon River Panel, a binational advisory body made up of American and Canadian representatives.

Panel members have haggled over escapement goals as runs have shrunk. For more than 20 years, the Alaska Department of Fish and Game, has opened — or closed — commercial and subsistence fishing so the target number of salmon can reach the Canadian border.

But this year, facing another summer of crisis on the Yukon, Canadian federal and American state officials want their draft agreement to shift the focus from escapement numbers to rebuilding the chinook population.

Relief can’t come soon enough for families like Freireich, who face deep economic and cultural losses with so few fish. The last several years have been particularly hard, as fishing for another staple subsistence species — summer and fall chum salmon — has also been partly or fully closed due to low runs.

Meanwhile, prices have surged at the local store. With food so expensive, fishing is essential to balance rural budgets. The rituals and cooperative work that come with the annual summer harvest also are part of what Freireich describes as “a very good life.”

“Our kids knew the definition of work and working together as a family,” she said. “At the end of the season, you came home with all of your fish and all of your stuff and your freezers were full and grandparents and families were happy.”

The draft agreement would not put many more fish into local hands right away. But there are limited opportunities to harvest for “ceremonial use and the transmission of cultural knowledge,” subject to managers’ discretion.

“We don’t want to completely kill culture for seven years while we try to rebuild these things,” says Doug Vincent-Lang, Alaska’s fish and game commissioner and the state’s top Yukon River negotiator. “We want to have a culture that’s preserved so that when the stocks do rebuild, that culture is alive and vibrant.”

Many Alaska tribal leaders oppose the new agreement in part due to a lack of tribal decision-making

Canadian First Nations members and Alaska Natives’ opinions on the draft agreement mirror their differing relationships with fisheries management on the two sides of the border.

In the Yukon, First Nations retained their own Indigenous subsistence rights in their overarching land claims agreements with the Canadian government. Closures to chinook harvests there must be agreed upon by First Nations and federal managers.

This leads to “a much better relationship than what I see on the Alaskan side,” says Elizabeth MacDonald, fisheries manager for a Whitehorse-based consortium of Yukon First Nations.

Rather than yielding to federal restrictions, First Nations like the Teslin Tlingit Council, southeast of Whitehorse, have voluntarily ceased fishing. Or they’ve strictly limited their catches to ceremonial use, as at a “first fish” camp run each summer by the Dawson City-based Tr’ondëk Hwëch’in government.

MacDonald, who previously worked for the federal Canadian Department of Fisheries and Oceans, is also a Yukon River Panel member.

Canadian rules barred her from speaking directly about the new draft agreement. But generally, in the Yukon, she said, “First Nation governments have to be consulted on things.” Federal managers, she said, will tell First Nations leaders: “‘Hey, guys, we’re thinking of doing this. What do you think?’ Or, ‘You want to do this. Can we help you?’”

The Alaska Native Claims Settlement Act grants no comparable set of harvesting rights to Alaska Native people, meaning that fisheries closures imposed by the state do not legally require the same level of tribal consultation as in Canada.

On the lower river, near the Bering Sea, such closures are recent and raw — in part because until the recent chum salmon crash, those fish were helping to keep residents’ freezers full even amid the absence of chinook. Closer to the border, in Alaska communities like Fort Yukon or Eagle that have been closed out of the king harvest for longer — and where chum don’t spawn — orders to stop fishing are still delivered by state managers, and come with the threat of net seizures and fines.

Alaska tribal members and organizations object to the lack of a formal consultation process by the Fish and Game Department, and the new draft agreement is no exception.

“They had ample opportunity to consult or present this agreement to tribal leaders, tribal organizations, tribal communities. But yet, they chose not to,” said Brooke Woods, a tribal member and salmon advocate in the Alaska village of Rampart.

Woods says the state doesn’t formally consult with tribes at all.

Vincent-Lang acknowledged that the state “hasn’t done a good job of incorporating some of the tribal information into our processes.”

But, he added, “We’re trying to figure out how to correct that.”

While tribes were not included in early draft negotiations, Vincent-Lang said he would consider taking their suggestions to Canada if they feel critical.

Tribes push for a federal takeover of Yukon salmon management

Along the lower Yukon, in the Deg Xitʼan Athabascan village of Anvik, Chief Robert Walker voices an opinion that’s echoed up and down the Alaska side of the river.

“Damn, I wish I was born earlier,” he said. “I would never have agreed on state waters.”

Walker is talking about the state of Alaska’s exclusive authority to manage Yukon fisheries on the American side. He fears that low salmon runs, which he blames in part on the state’s decisions, are making it impossible to carry on Deg Xit’an traditions.

Already, the Catholic Church and its historical policies of forced assimilation cast a long shadow over Indigenous culture along the lower and middle Yukon, where schoolteachers once intimidated residents, including Walker, who spoke Deg Xinag at local mission schools.

“When we were kids, when we talked in our language, they would whack us,” Walker said.

Summers spent at fish camp, away from church oversight, gave Walker and his family the chance to freely practice Deg Xit’an culture. Tending their smokehouse downriver kept the family busy during the chinook and summer chum runs. They’d put away about 150 chinook every season.

Today, there are not enough fish just for families to sustain themselves, and the Deg Xinag language is so endangered that the state says there are just two fluent speakers.

“I hear elders say, ‘God, I just really wish I had a fish head. Or even half of one,’” said Walker.

The frustration with the state has driven a desire among village residents to have the federal government take over fisheries management on the Yukon.

Tribal members see pros and cons to the idea.

The state allows any Alaska resident to subsistence fish on the river when it is open for harvesting, which is helpful for the many Native people who have moved away to larger cities or villages for work. Federal government subsistence rules only grant fishing rights to people who live along the river. But the state has not heeded calls to grant equal decision-making power to tribes, a practice called co-management. Co-management is when tribes and a state or federal entity jointly make decisions like run closures or allowable net sizes.

The only state-managed harvests in Alaska that fit this definition are for migratory birds, according to Sky Starkey, a longtime Anchorage-based Native rights attorney.

“And they’re mandated to do it by federal law, because there’s a treaty in place,” he said.

The federal government, meanwhile, has struck numerous co-management agreements with tribes. Just south of the Yukon River, on the Kuskokwim River, the U.S. Fish and Wildlife Service has formally co-managed salmon runs with a regional inter-tribal fish commission since 2016.

Earlier this month, the Yukon River Inter-Tribal Fish Commission filed a special action request with the Federal Subsistence Board, asking for federal management of the 2024 Yukon salmon run.

The request, according to commission chair Karma Ulvi, is for the federal government to “help us become stewards or co-managers of the river.”

While Ulvi and others may wish for co-management with the feds, Vincent-Lang fears the loss of state authority. One reason he’s eager to sign the draft agreement, Vincent-Lang said, is because he heard that First Nations entities were considering petitioning for Endangered Species Act protections for Yukon River chinook. Such protections could limit infrastructure development or natural resource harvests in communities along the river, Vincent-Lang said.

He said he did not know which First Nations were considering a push for those protections, however, and none of the First Nations members, their spokespeople, nor Canadian managers interviewed by Northern Journal said they had made such a request, or knew of one.

Alaska tribal leaders say cutting them out of the management process has dire consequences for the salmon, and they say that animals stop returning when people stop respecting them. Up and down the Alaska side of the river, residents decry the western practice of catching fish and throwing them back — a directive from state managers when a person fishing for other species accidentally catches a chinook in their wheel or net.

Benedict Jones, an elder from the village of Koyukuk, said the Indigenous Koyukon people are closely related to fish. “The elders told us when we were kids, they said, ‘Don’t bother the salmon. Don’t manhandle it. If you catch it, you gotta harvest it. Don’t throw it back in the river alive.’ And that’s what Fish and Game is doing,” he said.

The draft agreement calls for the U.S. and Canada to prioritize traditional and local ecological knowledge about chinook health to “better understand the causes of low run abundances and to identify possible solutions.” But U.S. tribal members are worried that with no formal consultation or co-management agreement, the bullet point could easily be ignored.

“That’s what our biggest goal is, co-management with the river, with tribes,” said Ulvi, chair of the inter-tribal fish commission on the Alaska side. “We feel like that’s the only way that we’re going to get conservation at this point, and using local and traditional knowledge and western science.”

Vincent-Lang said co-management already happens on the Yukon through advisory bodies up and down the river, and because of a public comment process at Alaska Board of Fisheries meetings.

But the advisory boards and Board of Fisheries both lack designated seats for representatives from tribal governments, and their decision-making processes do not include any consultation requirements with tribal leaders.

The new agreement could lay the groundwork for hatcheries along the river

The language in the draft agreement is not explicit, but Vincent-Lang said the shift toward a rebuilding goal may lead to new hatcheries on the river — a concept Canadian Yukon Panel members and First Nations leaders generally support, at least at a small scale.

Because Canadian First Nations are farther up the river, they’ve already endured decades of salmon shortages, unlike Alaska villages on the lower river. That’s created more openness to human intervention, according to three Canadian Yukon Panel members.

But on the Alaska side of the border, tribal members and some scientists are more skeptical, often citing evidence that hatcheries lead to increased prey competition at sea and make it more difficult for wild salmon to compete — along with other evidence that they’re simply not working.

Hatcheries run the gamut from tiny projects in spawning streams to industrial facilities with fish pens. Officials on both sides of the border say they are planning for small-scale, conservation-style hatcheries to preserve genetic diversity among fish. The ecological health of the Yukon watershed requires salmon, which is one reason Canadian First Nations are willing to entertain such proposals, according to MacDonald.

“They think it’s more important to have salmon there and continue to fill that ecosystem need, feeding the birds and the environment, than to let them spawn naturally and go extinct,” she said.

Salmon nourish eagles, ospreys, bears, lynx and a host of organisms in the waters where they die after laying their eggs — and their bodies, rich with nitrogen from the sea, fertilize the boreal forest along spawning streams.

There is already one hatchery in Whitehorse to help compensate for fish that die at a city dam, but MacDonald says its small scale has minimal impact and is not meant to provide commercial or subsistence harvests. MacDonald said she worries about what could happen if the U.S. were to one day use hatcheries on the Yukon River to boost the commercial fishing industry, as it has done elsewhere in Alaska.

“There should be quotas and limits on what each country can send out in the ocean,” she said.

Hatcheries in Alaska release more than a billion salmon into the ocean each year.

“Flooding the rivers and oceans with hatchery fish is not going to solve our problems,” said Ulvi, the chair of the Yukon Inter-Tribal Fish Commission.

Vincent-Lang has expressed excitement about the idea of hatcheries on the Yukon since as early as August 2021, three months into the crash in chum populations. “I’ll be dreaming of hatchery chinook and [chum] tonight!!!” he wrote in an email obtained through a public records request.

Vincent-Lang said fears over hatchery fish are misplaced, and he disputes the science that hatchery fish are competing with Yukon River chinook for food. The draft agreement, he said, isn’t contemplating “large-scale hatchery production right now on the U.S. side of the border,” and he added that the public would be involved in any discussions about significant hatchery expansion in the future.

One leading Alaska fisheries scientist, however, said he’s skeptical that any new hatcheries on the Yukon will help the struggling chinooks.

If hatcheries could restore river populations without causing more problems for wild fish at sea, they would have reversed the low chinook runs in Washington, Oregon and California by now, said Peter Westley, a biologist and professor of conservation and ecological studies at University of Alaska Fairbanks.

“It would be working, and it’s not,” he said. “Responding with a hatchery is a Band-Aid on a gushing wound.”

Westley said he is “embarrassed” that state leaders are considering hatcheries on the Yukon. The draft agreement also includes provisions for habitat restoration, which Westley considers a superior goal.

“Should you invest in hatcheries or should you invest in habitat? No brainer: Any effort going to hatcheries should go to habitat restoration and protection,” he said.

Yukon residents say agreement does not go far enough in addressing issues at sea

Along the Yukon, communities see constant signs of climate change — from unpredictable wildfire seasons to a mountain lion that musher Jody Potts-Joseph says has been spotted not far from her home in Eagle Village.

“We’re seeing the Yukon River widen,” Potts-Joseph told a group of University of Alaska Fairbanks students this past August. “You’ll also see a lot of erosion because of permafrost thawing.”

She described salmon dying of heatstroke in an overly -warm river.

The Yukon has been too warm for salmon in “many of the recent years,” as measured at Pilot Station in the lower river, said Katie Howard, a state biologist. “We’’re seeing temperatures there that could cause heat stress.”

Salmon are cold-adapted fish — and they eat other cold-water species. In the ocean, rising temperatures are shifting the Bering Sea’s ecosystem away from chinook’s usual prey. Fish that eat less may lack the fat and muscle they need for the long swim back to their spawning streams, and a warmer Yukon makes the journey more taxing. Weaker fish may also be more susceptible to ichthyophonus, a disease that is killing growing numbers of salmon in the Yukon before they can spawn.

But Alaska fishery managers and scientists do not have the power or authority to manage climate change. Nor was the Yukon River Salmon Agreement designed to tackle a warming world: Its purview is freshwater, not the many years kings spend at sea.

Alaska managers can only control how many fish people catch in the state’s ocean waters — which extend just 3 nautical miles offshore — and whether hatcheries are putting fish back into the ocean. They can create and restrict. Yukon River residents say the state is handing most of the restrictions down onto them — including in the new draft agreement with Canada.

“I think the biggest revision that the people want to see incorporated into that agreement was more managing marine activity,” said Serena Fitka, the executive director of the Yukon River Drainage Fisheries Association and a member of a tribe in the village of St. Mary’s.

Ulvi, the chair of the Yukon River Inter-Tribal Fish Commission, agrees.

“A lot of our issues are happening in the marine environment with bycatch and intercept fisheries, and we really need to concentrate on that area,” she said. “And not make the tribes along the Yukon the ones that have to bear the burden of conservation.”

Last summer in Galena, a flat, dusty, low-lying Alaska village bookended by rolling hills, Gilbert Huntington ate a lunch of sheefish he fileted and pondered the trawl industry killing Yukon River fish at sea.

Those factory vessels catch huge numbers of pollock, a flaky whitefish that’s made into fish sticks and sandwiches.

But the ships also accidentally scoop up chinook and chum salmon as “bycatch” in their large commercial nets. Chinook bycatch limits are set by the North Pacific Fisheries Management Council, a federal commission that requires observers to record each salmon killed by trawlers at sea.

Huntington says bycatch is being prioritized over human life. Like other residents, he connects fishery closures in the 1980s to increases in suicides along the river at the time, as residents were disconnected from traditions, culture, and meaningful work.

“We’re killing people. Just so we can have some imitation crab,” Huntington says, referring to one of the products made from pollock. “I don’t care how many billions of dollars anybody’s gonna make. If it causes one person to lose their life, forget it.”

The pollock industry markets itself as sustainably managed, for both pollock and salmon. Between 2017 and 2022, chinook bycatch in pollock nets averaged some 20,000 fish per year, under the federal limit of 33,318 kings. Genetic testing indicates that between 1% and 2% originate in the middle and upper Yukon, while fish born in coastal Western Alaska rivers — which includes the lower Yukon and other areas — varies from less than 9% to over 50% depending on the year.

Bering Sea trawlers have substantially reduced their chinook bycatch numbers in the past few years, said Eric Deakin, chief executive at Coastal Villages Region Fund, a Community Development Quota group that includes pollock fishing in its portfolio.

Established in 1996, CDQ groups like Deakin’s are nonprofit corporations that were granted shares of each Bering Sea fishery to support economic development and other programs in Native communities within 50 miles of the Western Alaska coast. That means some of the Yukon River residents who criticize the trawl industry live in communities that benefit from its profits — and it means that Deakin’s organization is especially sensitive to those complaints.

If salmon start showing up their nets, he said, trawlers now leave the area — an expensive decision that can cost vessels more than $100,000, he added.

It’s not just for optics, he said. “As far as CDQs go, we want to see as many fish get back to the river so future generations are stronger”

The almost 3 billion pounds of pollock harvested each year is, by weight, the largest fishery in North America.

But the very scale of the trawler fleet might feed back into the ocean’s broader warming problem. A 2021 study by U.S. and Canadian researchers contends that the drop in fish biomass caused by industrial fishing worldwide has reduced the ocean’s ability to store carbon. And it says the impact is most acute in cold-water ecosystems like the Bering Sea.

Potts-Joseph, in Eagle Village, says climate change makes it even more important to “do something about bycatch,” as it’s an issue that can be addressed quickly. Like many Yukon residents, she thinks it is now imperative that every chinook possible survive to spawn — meaning any fish caught in the river or at sea is one too many. It’s a sentiment widely shared along the river, where Indigenous fishers note that even a low bycatch year — like 2023, with fewer than 12,000 chinook reported killed at sea — was more than Canadian First Nations have caught for subsistence any year in the past 20.

Deakin says the focus on bycatch is because “it’s a lever to pull.”

“The climate change lever is a lot harder to pull,” he says. But he warns that the pollock fleet harvests so few Yukon-bound salmon that even a complete closure wouldn’t allow Yukoners to start fishing — while it would destroy jobs and other programs that CDQ groups like his fund in Western Alaska.

“In terms of upriver, I don’t know what to tell them,” Deakin says. “If we caught one fish and that was it, would they still like us to shut down because they can’t catch one?”

Deakin argues that the real threat to Yukon salmon comes from intercept fisheries and the billions of hatchery fish that Russia, Japan and the U.S. release into the sea. Along the river, residents share concerns about the impact of intercept fisheries and hatcheries, as well as bycatch.

Basil Larson, a fisher and dog musher in the village of Russian Mission, notes how many years Native communities have been barred from fishing, while the trawlers continue. “We’ve been doing it, so it’s their turn to try to do it,” he says, referring to fisheries closures. Larson says he gets frustrated when state managers point to climate change as the main cause of salmon decrease. “I guess [they] try to deflect attention away from where attention has to be,” he says, “the wanton waste with the commercial industry.”

In the middle river village of Kaltag, where the population has shrunk by one-fourth over the last two censuses, Justin Esmailka also attributes the low salmon runs to the big businesses at sea.

“The greed of the people out there in the ocean is killing our way of life,” he says.

Vincent-Lang, the fish and game commissioner, is expected to debut the new draft agreement to river residents at a town hall-style listening session Tuesday in Fairbanks. But he has made it clear he intends to come to the next Yukon River Panel meeting, in April, with the agreement signed by both sides.

“It sounds like it’s a done deal already. It sounded like they just wanted to let everybody know,” said Fitka, the nonprofit director.

Though the draft agreement allows for salmon fishing for certain cultural exceptions, Woods, the advocate in the village of Rampart, says culture does not occur only at funerals or at potlatches. It’s a summer spent at fish camp, cutting hundreds of fish to put away for elders who can no longer harvest their own. It’s pulling dry fish from the freezer to take on a winter moose hunt. It’s daily life.

“Our kids, they need to grow up with the taste of salmon and to be out on the land and water with their family,” Woods said. “We need the mental, physical, spiritual and cultural benefits of salmon.”
