Counting salmon is a breeze with airborne eDNA

December 1, 2025 — During the annual salmon run last fall, University of Washington researchers pulled salmon DNA out of thin air and used it to estimate the number of fish that passed through the adjacent river. Aden Yincheong Ip, a UW research scientist of marine and environmental affairs, began formulating the driving hypothesis for the study while hiking on the Olympic Peninsula.

“I saw the fish jumping and the water splashing and I started thinking — could we recover their genetic material from the air?,” he said.

The researchers placed air filters at several sites on Issaquah Creek, near the Issaquah Salmon Hatchery in Washington. To their amazement, the filters captured Coho salmon DNA, even 10 to 12 feet from the river. Scientists collect environmental DNA, or eDNA, to identify species living in or passing through an area, but few have attempted to track aquatic species by sampling air.

This study, published Nov. 26 in Scientific Reports, shows that eDNA can move between air and water — a possibility scientists hadn’t accounted for even though aquatic animal DNA sometimes appears in airborne study data.

The researchers then merged air and water eDNA with the hatchery’s visual counts in a model to track how salmon numbers rose and fell during the fall migration. Although the amount of salmon DNA in the air was 25,000 times less than what was observed in the water, its concentration still varied with observed migratory trends.

“This work is at the edge of what is possible with eDNA,” said senior author Ryan Kelly, a UW professor of marine and environmental affairs and director of the eDNA Collaborative. “It pushes the boundaries way further than I thought we could.”

OREGON: Oregon delays Dungeness crab season after Washington testing falls short

November 25, 2025 — Officials in the U.S. state of Oregon have decided to delay the state’s commercial Dungeness crab season by at least two weeks, despite preseason testing showing that the state’s crabs met the regulatory threshold for meat recovery.

In a 21 November announcement, the Oregon Department of Fish and Wildlife (ODFW) declared that it would be pushing back the season opening from 1 December to 16 December due to testing in Long Beach, Washington, the only site to show lower meat recovery levels.

OREGON: Commercial Dungeness season delayed until at least Dec. 16, ODFW announces Friday, to wait for Washington improvements

November 24, 2025 — Oregon’s commercial Dungeness crab season is delayed coastwide until at least Dec. 16, the Oregon Department of Fish and Wildlife announced Friday.

Dungeness crab along the Oregon coast met both meat and safe biotoxin level requirements, however the ODFW said the season will be delayed as crab tested in the Long Beach, Wash. area have not yet met the meat fill requirement.

In a news release Friday, the ODFW said most Dungeness crab advisory committee members supported the delay as it is least disruptive to traditional fishing patterns and may improve market conditions. The tension comes because if the Washington season is closed and the Oregon season is open, then Washington crabbers with permits for both states move their operations to the north Oregon coast, putting extra pressure on the fishery.

WASHINGTON: Washington crabbers hope for a December start

November 19, 2025 — As crews along Washington’s coast splice rope, paint buoys, and stack their pots, the region’s commercial crab fleet is once again preparing for what the Chinook Observer calls the most prized fishery in the Pacific Northwest. According to an article published by the Observer on Nov. 16, the official start to the 2025 Washington commercial Dungeness crab season could come as early as Dec. 1 if the preseason test results for meat recovery and domoic acid meet the criteria.

The first round of tests delivered mixed results. Long Beach came close, but at 20.9 percent recovery on Nov. 3, it fell just shy of the 23 percent threshold required along the Washington and north Oregon Coasts. Other major test sites performed well above the cutoff: Astoria at 26.4 percent, Westport at 25 percent, and Garibaldi at 27.1 percent.

WASHINGTON: Upper Skagit Indian Tribe celebrates huge rebound of Baker River sockeye

October 17, 2025 — Nearly 92,000 sockeye salmon returned to the Baker River this year. That’s a historic milestone for nearby tribes, state wildlife officials and the hydroelectric utility that caused the decline — and helped bring the fish back.

Scott Schuyler, the Upper Skagit Indian Tribe’s policy representative for cultural natural resources, has been watching the fish run for more than 40 years.

“We basically lost this run,” said Schuyler, a tribal member and elder. “Back in 1985 the run went down to 80-ish or so fish, which is basically extinct. And it was due to hydropower that caused their demise, and it was hydropower that helped fix the run to get to where we are today.”

Schuyler said the tribe once had a fishing village called S.báliuqʷ (pronounced ‘sih-’BALL’-ih-QUE’) on Baker Lake.

“That’s where people lived and died and fished and hunted since time immemorial,” he said.

WASHINGTON: WA pink salmon populations surge in some Puget Sound areas, stagnant in others

September 10, 2025 — The Puget Sound region is anticipating a substantial increase in pink salmon returns for 2025, with forecasts predicting a total of 7.76 million fish. This figure represents a 70% rise from the 10-year cycle average and is expected to be the third-largest return on record. However, some populations, like the Chinook salmon stocks, are expected to limit some salmon fisheries in the upcoming season.

The forecast marks a significant improvement from the 2023 prediction of 3.95 million, with the actual return reaching 7.22 million. The Green and Nisqually rivers are expected to see strong pink salmon returns, further contributing to the region’s positive outlook.

Dig deeper: The Washington Department of Fish and Wildlife (WDFW) has responded to the promising forecast by increasing the daily limit for pink salmon in all inner-marine areas through Sept. 30 to two additional pinks. Marine Area 8–2 remains closed due to the Stillaguamish River’s inability to meet spawning escapement goals.

US FDA recalls more shrimp after discovering radioactive contaminant

August 22, 2025 — The U.S. Food and Drug Administration has announced a voluntary recall of frozen shrimp products due to possible contamination with Cesium-137 (Cs-137), a man-made radioisotope that can elevate cancer risks through longer term, repeated low dose exposure.

The announcement comes shortly after U.S. Customs and Border Control (CBP) detected Cs-137 in shipping containers at the Ports of Los Angeles, Houston, Savannah, and Miami, with agents finding evidence of the radioisotope in a single shipment of frozen bread shrimp. The discovery led the FDA to issue an alert for frozen shrimp supplied by Indonesia-based PT. Bahari Makmur Sejati to Walmart and sold under the “Great Value” brand name.

Trump revokes agreement to protect salmon

July 28, 2025 —A September 2023 presidential memorandum of understanding (MOU) from the Biden administration called for the elimination of four Snake River dams that the MOU said contributed to the near extinction of 13 salmon and steelhead fish populations that return each year to the Columbia Basin from the Pacific Ocean to spawn.

Supporters of the Biden MOU say the fish are important to local tribal health and sovereignty and to basin ecosystems, and the declines are affecting southern resident orcas off the coasts of British Columbia, Washington, and Oregon. The orcas eat the salmon.

The 2023 agreement was between the federal government and four Lower Columbia River tribes — Confederated Tribes and Bands of the Yakama Nation, Confederated Tribes of the Umatilla Indian Reservation, Confederated Tribes of the Warm Springs Reservation of Oregon, and the Nez Perce Tribe, as well as the states of Oregon and Washington. The tribes want the dams removed.

Opponents argue that the dams support river navigation for maritime barge operations, passenger vessels, irrigation, and emissions-free hydropower for nearby communities and should be maintained.

Marine heatwaves impact maturation of black rockfish

July 24, 2025 — A newly released study by Oregon State University and NOAA Fisheries researchers shows that marine heat waves in increasing frequency are having an impact on the growth and maturation of black rockfish in Oregon and Washington.

“We do know that the occurrence of marine heatwaves is more often and more intense,” said Claire Rosemond, now a fisheries biologist at NOAA Fisheries’ Northwest Fisheries Science Center in Newport, Ore. “There are some monitored ocean indicators that can help us understand if the coming year would be warmer or cooler, but it is harder to predict how hot or how cold.”

Results of her dissertation while at OSU with fisheries biologist Melissa Head, also of the Northwest Fisheries Science Center, and Scott Heppell, a professor at OSU ‘s Department of Fisheries Wildlife and Conservation Sciences, were published on June 3 in the journal Ecological Applications.

The study investigated the impact of intense and less intense marine heatwaves on black rockfish reproduction and growth along the Pacific Coast between 2014 and 2021.
They found that while black rockfish exhibited elevated growth during intense marine heatwaves, their maturation was delayed. In fact, during intense marine heatwaves, maturation was postponed, reproductive success was lower by one third, and parasite prevalence in ovaries was nominally high.

Younger females were large at age during intense marine heatwaves, and throughout the last decade, growth rate coefficients were higher than what is typically expected for slower-growing fishes like rockfishes.

Viewpoint: Why the fight for Washington’s net pens matter

July 24, 2025 — In January, a sweeping and controversial regulatory decision by the Washington State Board of Natural Resources stunned a unique and diverse coalition of pro-science advocates working to preserve native-species, net-pen aquaculture in Washington state.

The coalition opposing the ban included local aquaculture companies and members of the Northwest Aquaculture Alliance (NWAA), current fisheries scientists from institutions like the University of Washington, Washington State University, and the University of Idaho, as well as former NOAA and state agency scientists, local Tribes, and dozens of regional farmers and aquaculture workers. Together, they urged the Washington Department of Natural Resources (DNR) to pursue a science-based, transparent approach in addressing concerns regarding net-pen aquaculture.

Instead, the Washington DNR Board voted to adopt a rule permanently banning all net-pen farming of native fish species on state-managed aquatic lands. In response, NWAA has filed a legal challenge seeking to overturn the rule, asserting that DNR exceeded its statutory authority and conducted a procedurally flawed process lacking in scientific integrity and public accountability.
