ALASKA: For Yukon River residents, salmon shortages have health consequences

Juky 24, 2026 — When 26-year-old Tirzah Bryant was a kid, she knew how to watch the cottonwood trees along the Yukon River for the sign that it was time to fish for salmon.

“We know that the fish are coming when the cotton’s flying from the cottonwood,” she said.

But run collapses and successive fishing closures along the river have rendered the cottonwood signal meaningless.

“I remember that first summer that we couldn’t fish, watching the cotton flying and being like …what it felt like, I was drifting. I’m like, ‘What am I doing?’” she said. That drifting feeling includes interactions with members of her extended family who had moved to cities but used to gather in Galena during fishing season. “They don’t have a reason to come home now,” she said.

Bryant described that odd feeling during a presentation in March at an Anchorage tribal environmental conference. A 2025 graduate of the University of Alaska Fairbanks’ Center for One Health Research master’s degree program, which focuses on the human-animal-environmental health connections in Alaska and the Arctic, she described the One Health concept as fitting perfectly with her family’s traditions.

“Everything is related. So a healthy environment equals healthy animals, which equals healthy humans,” said Bryant, who also holds a biology degree from UAF and is now the environmental and education coordinator for the Louden Tribe, the Galena-based tribal government.

That makes the collapse of runs in the Yukon River — where Indigenous residents’ culture is tied to communal salmon harvesting, preparation and eating — “very detrimental to our people,” she said.

On the Yukon River, salmon runs that used to support a thriving and lucrative commercial harvest have collapsed. The runs of Chinook, also called king salmon, that have been in steady decline since the early 2000s, took a nosedive in recent years; by 2022, Chinook abundance was down 81% below its long-term average, according to fishery biologists. Harvest closures that began in 2020 were extended, and in 2024 an Alaska-Canada agreement established a seven-year moratorium on Chinook salmon fishing in the river to preserve Canadian-origin stocks.

Runs of chum salmon, a species that is generally more abundant in the river, suffered a similar but more sudden crash. A series of chum-harvest closures, even for subsistence purposes, started in 2020, and by 2022 abundance had fallen 92% below the long-term average.

Several factors, working in combination, are blamed for the declines. Scientists cite multiple climate change effects in both the ocean and freshwater bodies used by salmon. Those changes have not only affected the raw numbers of fish but also contributed to the shrinking size of salmon, resulting in smaller egg loads carried to spawning grounds by females.

Other factors cited are interceptions at sea by trawlers targeting groundfish species like pollock, changes forced by increasing loads of Asian hatchery fish in the ocean, past fishery management practices and the parasite Icthyophonus, which thrives in warmer conditions and has a more detrimental effect on Yukon Chinook than on any other type of salmon.

Salmon-protection activists say there is not much that can be done in the short term in Alaska to address those factors, other than to adjust fishery management to cut down on at-sea interception, also known as bycatch.

ALASKA: A parasite that thrives in warm conditions adds to Yukon River salmon woes

July 23, 2026 — When Stan Zuray began noticing white spots, a mushy texture and a weird “sour watermelon” smell in the Chinook salmon he was pulling from the Yukon River, he knew something was going wrong.

That was back in the 1980s. By about 1990, he and others just stopped fishing what he calls “the ass end of the king run” because the fish were so low in quality, he said.

Everyone stopped fishing earlier than normal, he said. “You just get tired of the bum-looking fish,” said Zuray, who lives in the village of Tanana but still has his Boston accent after spending half a century in the Alaska Bush.

It was an ominous turn for a river famous for producing some of the world’s biggest and most prized wild salmon. Chinook salmon, also known as king salmon, is so exalted among the five Pacific salmon species that it is designated Alaska’s official state fish. And the Yukon River Chinooks were traditionally considered among the best of the best.

The culprit in the mushy, weird-smelling salmon was Ichthyophonus, a parasite found in oceans around the world, but a particular menace to the health of Yukon River Chinook salmon.

Zuray is known nationally as a featured character in the reality TV show “Yukon Men” and from his own YouTube broadcasts and a biographical documentary. Within Alaska fishing circles, he is well known as a former subsistence representative on the Alaska Board of Fisheries.

In the science community, he is known for his work as one of the early Yukon River Ichthyophonus researchers. He set up a program and documented infection rates at Rampart Falls, a spot on the river near the tiny Alaska village of Rampart, collecting data that has become critical to current studies.

Zuray said he could smell the infection as fish dried on racks in the traditional way and the parasite multiplied rapidly in the warm sunlight. He dissected samples and documented how Icthyophonus attacks a salmon’s heart. “I squish it in my hand by closing my fingers, and the heart will ooze out through my fingers,” he said.

Bering Sea heat wave cited as trigger for nosedive in Yukon River Chinook salmon

July 13, 2026 — The intense marine heat wave conditions that began roiling the Bering Sea in about 2016 resulted in the lowest winter sea ice extent measured in 150 years, widespread bird and marine mammal die-offs, a drastic shift in fish populations and a crash of snow crab stocks.

Now new research is tying the marine heat wave to the recent collapse of Yukon River Chinook salmon.

A study published in April, written by scientists at the National Oceanic and Atmospheric Administration’s Alaska Fisheries Science Center and University of Alaska Fairbanks, showed the correlation between the extreme heat wave conditions and the nosedive in Yukon River Chinook stocks. The heat wave was accompanied by a dramatic increase in deaths of older juvenile and adult Chinook that, had they survived, would have returned from the ocean to freshwater spawning grounds, the study found.

The study was published in the journal Ecological Applications.

The Yukon River’s runs of Chinook, also called king salmon, have been in a long-term decline since their past heyday, when they numbered in the hundreds of thousands and the river was one of the biggest sources of that salmon species.

The sharp downturn in recent years resulted in a 2022 return that was the lowest on record. Widespread fishery closures have been in effect for years along the Yukon River system in both Alaska and Canada.

Alaska Supreme Court upholds dismissal of lawsuit challenging Yukon-Kuskokwim salmon management

October 13, 2025 — Alaska judges will not hear a lawsuit alleging that the Alaska Department of Fish and Game has mishandled the state’s valuable salmon returns.

On Friday, the Alaska Supreme Court upheld a lower-court decision that dismissed a case brought by Juneau resident Eric Forrer in 2022.

Forrer had argued that years of declining salmon returns in the Yukon and Kuskokwim Rivers clearly showed that the department was violating a section of the Alaska Constitution that requires fish be managed for sustained yield.

Forrer, a long-time Alaska resident, has a history of personal-use and commercial fishing, including on the Yukon River.

In his suit, he sought a declaration confirming that the Fish and Game was violating the constitution and sought an injunction directing the department “to fulfill the sustained yield mandate.”

Bethel Superior Court Judge Nathaniel Peters dismissed the case in 2023, but Forrer appealed to the Alaska Supreme Court.

In an 18-page order published Friday, the five-member court said unanimously that because Forrer didn’t challenge a specific policy, law or regulation, Peters was correct and the case should be dismissed.

ALASKA: Indigenous leaders, scientists, and policy makers call for bold actions to address Yukon River salmon crisis

August 5, 2025 — Tribes should be allowed to harvest the same number of Yukon River chinook salmon that trawlers scoop up in the Bering Sea as bycatch, and an independent review is needed to better manage the salmon crisis on Alaska’s longest river. These are just two of the recommendations outlined in a recent policy brief that looks at near-term strategies for addressing the crisis on the Yukon.

Doug DeMaster, a retired biologist who spent nearly two decades with the top federal fisheries agency, the National Marine Fisheries Service (NMFS), co-authored the brief published in the journal Arctic, Antarctic, and Alpine Research (AAAR).

“What we tried to do in this brief is put together a document that identifies what’s needed, what’s wanted, and tries to do it in a way that’s easily amenable to Congress, and politicians, and both state and federal agencies,” DeMaster said.

The two-page document was assembled by a mix of tribal leaders, scientists, and policy makers. It boils down potential factors driving crashes for both chinook and chum salmon on the Yukon River. Among them: bycatch and ecosystem changes in the Bering Sea driven by the pollock fishery, warmer water temperatures, competition with hatchery salmon, the Area M intercept fishery, and increasing rates of parasitic infection in Yukon River chinook.

ALASKA: Alaska experts recommend management overhaul to rescue Yukon River salmon runs

August 4, 2025 — A management overhaul is needed to address the faltering salmon runs in the Yukon River and the widespread harms that have resulted from shortages of fish along the river’s basin, according to a report by Indigenous leaders and Alaska scientists.

The report, a peer-reviewed policy brief published in the journal Arctic, Antarctic, and Alpine Research, proposes an independent review of Yukon River chinook and chum salmon issues by an entity like the National Academy of Sciences. It also recommends bigger management and science roles for Indigenous residents who live along the river, which flows nearly 2,000 miles from Canada’s Yukon Territory to the Bering Sea.

Building relationships between tribal members and government managers will likely require long-term effort, says the report, which has co-authors from various organizations, including the University of Alaska Fairbanks.

“Trust between Indigenous communities and fisheries scientists and managers needs to be enhanced by continuously, transparently, and equitably combining quantitative fisheries analyses with Indigenous Knowledge,” the report says.

The report recommends a “cultural exemption” for small-scale personal harvests by river residents to help address inequities between commercial and subsistence fishermen.

Small fish size linked to poorer runs of chinook in Alaska’s biggest rivers

December 9, 2024 — The shrinking size of Alaska salmon, a decades-long trend linked in part to warming conditions in the ocean, is hampering the ability of chinook in Alaska’s two biggest rivers to produce new generations needed to maintain healthy populations, a new study shows.

The University of Alaska Fairbanks-led study shows how the body conditions of chinook salmon, also known as king salmon, combined with extreme heat and cold in the ocean and freshwater environments, have converged in the Yukon and Kuskokwim river systems to depress what is termed “productivity” — the successful reproduction that results in adult spawners returning to the same area.

The study examines 26 different populations of chinook in those two river systems in areas from Western Alaska to the Yukon River uplands in Canada. Chinook runs in those rivers have faltered in recent years, and the situation has been so dire on the Canadian part of the Yukon that U.S. and Canadian officials earlier this year suspended all harvests of Canadian-origin chinook for seven years.

The analysis of multiple factors and conditions revealed that fish size was a major factor that determined productivity, defined as adult salmon returning to spawning grounds successfully producing a next generation of adults to come back to the same spawning area.

UAF study links declining salmon to extreme climate, smaller size

December 4, 2024 — A new University of Alaska Fairbanks (UAF) study published in the scientific journal Global Change Biology, says extreme climate and smaller body size have led to declining Yukon and Kuskokwim Rivers’ King Salmon populations.

Over the last decade, the lower number of certain salmon species making it to rural Alaska villages, along the two tributaries, has led the Alaska Department of Fish and Game to impose catching restrictions.

UAF researcher Erik Schoen said the study began in 2020, and examined 26 different spawning areas across the two river basins.

“Across the board, there were a few big drivers that affected all of these populations. Some of those were out in the ocean. So ocean climate, extreme conditions like really cold winters and really hot summers in the ocean had big negative effects,” Schoen said.

Yukon cyanide spill raises concern for Alaskan salmon

July 31, 2024 — Concern spread across Canada after a cyanide spill at a gold mine in the Yukon Territory. The incident happened at Victoria Gold’s Eagle Mine, where a heap leach failure and landslide occurred. Energy, Mines, and Resource Minister John Streicker said four water samples were taken from different areas near the mine and had come back positive for cyanide, but levels were primarily low.

According to Alaska Beacon, Alaska salmon advocates say the spill isn’t just an issue for Yukoner. The spill happened upstream of a tributary of the Yukon River, and concerns spread because the Yukon is the state’s biggest transboundary waterway.

The spill happened in late June, and officials from Canada and the U.S. said it was too early to know its full impact and advised residents that there weren’t likely any associated health risks. Still, salmon advocates fear that the pollution that hasn’t been fully contained could worsen matters for the Yukon River’s struggling species. Residents along the area’s shores have depended on salmon for generations. Brooke Woods, a tribal member and salmon advocate in Rampart, told Alaska Beacon, “Now, we have a new threat to our salmon.”
