Northwest’s Salmon Population May Be Running Out of Time

January 21, 2021 — A Washington State report put it bluntly: Because of the devastating effects of climate change and deteriorating habitats, several species of salmon in the Pacific Northwest are “on the brink of extinction.”

Of the 14 species of salmon and steelhead trout in Washington State that have been deemed endangered and are protected under the Endangered Species Act, 10 are lagging recovery goals and five of those are considered “in crisis,” according to the 2020 State of Salmon in Watersheds report, which was released last week.

“Time is running out,” said the report, which is produced every other year by the Washington State Recreation and Conservation Office. “The climate is changing, rivers are warming, habitat is diminishing, and the natural systems that support salmon in the Pacific Northwest need help now more than ever.”

Researchers say recovery efforts — involving state and federal agencies, Native American tribes, local conservation groups and others — have helped slow the decline of some salmon populations. The report found that two species — the Hood Canal summer chum and Snake River fall chinook — were approaching their recovery goals. It also noted that no new salmon species had been added to the endangered list since 2007.

PFMC Adopts Salmon Measures to Help Southern Resident Killer Whales

November 25, 2020 — The Pacific Fishery Management Council unanimously adopted new ocean salmon fishing regulations last week to help save critically endangered Southern Resident killer whales from extinction. While the birth of two calves this year was welcome news, Southern Residents face an uncertain future with only 74 individuals left and a diet almost entirely comprised of declining salmon populations, especially Chinook salmon, Oceana said in a press release.

Pacific salmon, primarily Chinook salmon, are 99 percent of the diet of Southern Resident killer whales. A single adult Southern Resident typically needs to eat 12 to 20 Chinook salmon every day, and as many as 30 depending on the size and nutrition levels of the fish. Wild salmon populations have been in decline due to a combination of issues, including dams, habitat loss and fishing pressure, Oceana said.

NOAA Veterans Corps: Progress By The Numbers

November 12, 2020 — The following was released by NOAA Fisheries:

The NOAA Veterans Corps provides opportunities for military veterans to build their skills and work experience contributing to habitat and fisheries restoration projects.

Through strong partnerships, the year-long paid training program for veterans includes marine and freshwater restoration for native fish and other natural resources. Participants also conduct research and monitoring to track the progress of fish restoration projects and fish populations. These efforts are helping different threatened and endangered species recover, including:

Here are a few key metrics to help understand the NOAA Veterans Corps partnerships impact.

  • 8 years: Established in California in 2012, NOAA Veterans Corps partnerships have grown ever since.
  • 3 states: We now have veterans corps partnerships in California, Oregon and Washington. Each state has a unique experience for veterans, with different levels of field, research and community outreach opportunities to help prepare them for longer-term careers in resource management.
  • 22 partners: Throughout those states, we’re working with partners to help shape the unique veterans corps experiences.
  • 50+ veterans: In 2020, we have 14 veterans participating, and more than 50 have participated since the partnerships started in 2012. Many of these veterans furthered their education and gotten jobs in state and tribal natural resource agencies. A recent Washington participant even got hired to work at NOAA!

Protecting the Critical Value of Nearshore Habitat

November 11, 2020 — The following was released by NOAA Fisheries:

No habitat in Puget Sound is more valuable to threatened Chinook salmon than nearshore habitat. No habitat is more degraded, either.

Nearshore habitat is shorthand for tidal marsh, wetlands, and river estuaries where land and water combine to support life of all kinds, from shorebirds to juvenile salmon and steelhead. Juvenile Puget Sound Chinook salmon spend their first critical months in saltwater feeding and growing in the sheltered water of nearshore habitat.

Their growth in that pivotal window determines in large part whether they will make it back to rivers as adults to spawn. With nearshore habitat dwindling, most do not.

When reviewing projects, NOAA Fisheries is updating its efforts to avoid further losses of nearshore habitat.

“It is important for projects to have a path forward, while we also need to stem the losses of this habitat that we have already lost so much of,” said Kim Kratz, Assistant Regional Administrator in NOAA Fisheries West Coast Region.

More than 95 percent of the most valuable nearshore habitat in Puget Sound is gone and is especially scarce in the south Sound, according to an analysis by the Puget Sound Nearshore Ecosystem Restoration Project. Scientists described it as a “dramatic change in the historic occurrence [of] these once-prominent nearshore ecosystems.”

Fewer than one percent of Puget Sound Chinook salmon juveniles that migrate to the ocean each year survive to return as adults. That means that already imperiled populations continue to decline. There are also repercussions for other species such as en

ALASKA: 2020 Salmon harvest in Southeast less than half of previous year’s

November 10, 2020 — Southeast Alaska’s salmon harvest was less than half of last year’s haul. That’s according to a preliminary report from the Alaska Department of Fish and Game released on Monday.

Commercial fishermen in Southeast harvested just over 14.3 million salmon across the five species this year — almost 5 million chum salmon, 8 million pinks and 1.1 million coho. For sockeye, the harvest was about 373,000 and 200,000 Chinook.

That’s a drop in harvest for every species except Chinook — also known as king salmon — which increased by a few thousand fish this year. In other words, Southeast’s total salmon harvest was 19 million fewer fish than last year.

The preliminary ex-vessel value of Southeast’s 2020 salmon fishery was just over $50 million dollars. That’s less than half of 2019’s estimated value, and the third consecutive year that Southeast’s value paid to fishermen has dropped.

Salmon study sheds light on why fall-run fish are bigger than their spring-run cousins

October 30, 2020 — For the Yurok people, who have lived at the mouth of the Klamath River for generations, the spring run of Chinook salmon (Oncorhynchus tshawytscha) is a welcome—and nutritious—relief from winter. But as the fish have dwindled to just a fraction of their original numbers, Indigenous groups there are pushing to have them protected by the Endangered Species Act. New research, which suggests genes play only a small role in distinguishing the spring salmon from their fall-run cousins, may call into question the need for such a designation.

The rivers of the Pacific Northwest used to teem with two waves of Chinook: those that arrived in March or April, and those that came 6 months later, swimming from the sea to their upriver breeding grounds. Although technically the same species, the spring-run and fall-run fish have some “iconic differences,” says Eric Anderson, a molecular geneticist at the National Oceanic and Atmospheric Administration’s Southwest Fisheries Science Center. Spring salmon are smaller, fattier, and less sexually mature than fall fish. They also swim further upriver to breed.

To tease out the genetic basis of those differences, Anderson and colleagues teamed up with Yurok fishers living at the mouth of the Klamath River in northern California. Together, they examined 500 fish as they started their upstream journeys in all four seasons. The researchers measured the size of each fish, assessed its fattiness and reproductive status, and took samples of its DNA. The researchers gathered similar data from other rivers.

Past studies have shown that a small region of the salmon chromosome 28 contains two genes, GREB1L and ROCK1, that vary between spring and fall salmon. Anderson and his colleagues did further genomic studies, sequencing the whole genomes of 160 fish in the hopes of linking the two genes to the spring and fall traits. The data set is “impressive” and the work unique says Sheela Phansalkar Turbek, an evolutionary biologist at the University of Colorado, Boulder, who was not involved with the work.

Small Genetic Difference Determines Chinook Salmon Migration Timing, New Study Shows

October 30, 2020 — The following was released by NOAA Fisheries:

The annual migration of Chinook salmon up West Coast rivers from the ocean has enriched ecosystems, inspired cultures, and shaped landscapes. Yet the timing of their migration is controlled by one small section of their genome, according to research published this week in Science.

This is the first time scientists have linked a single gene region to such an influential difference in a vertebrate species. For salmon, it determines whether they return upriver from the ocean in spring or fall. This has crucial implications for other species that rely on them for food. First author Neil Thompson of the University of California Santa Cruz and NOAA Fisheries’ Southwest Fisheries Science Center said that this small genetic difference can have a major effect on a complex pattern of migration and reproduction.

Fish migrating upriver in spring may access habitat such as higher elevation tributaries. These habitats become less accessible to Chinook salmon migrating later in the year when stream flows decline. The result is that fall-run Chinook salmon remain lower in the watershed without continuing up into the tributaries.

However, the construction of dams in the West blocked spring-run Chinook salmon from much of their original spawning habitat. This contributed to the listing of several spring-migrating fish under the Endangered Species Act. Fall-run Chinook salmon on the West Coast are generally more abundant.

The scientists identified the gene region influencing migration with whole-genome sequencing. Then, they scientists examined the genetic pattern in more than 500 Chinook salmon caught by the Yurok Tribe in the Klamath River estuary. They analyzed the effects of variation in this genetic region on migration timing and other physiological traits.

Alaska’s salmon are shrinking, and climate change may be to blame

August 21, 2020 — Alaska’s highly prized salmon – a favorite of seafood lovers the world over – are getting smaller, and climate change is a suspected culprit, a new study reported, documenting a trend that may pose a risk to a valuable fishery, indigenous people and wildlife.

The study, led by University of Alaska at Fairbanks (UAF) scientists, found that four of Alaska’s five wild salmon species have shrunk in average fish size over the past six decades, with stunted growth becoming more pronounced since 2010.

Hardest hit is Alaska’s official state fish, the Chinook salmon, also known as king salmon.

Chinooks on average are 8 percent smaller than they were before 1990, according to the study, published on Wednesday in the journal Nature Communications. Also shrinking are Alaska’s sockeye, coho and chum salmon, the report said. The findings are based on data from 12.5 million samples collected over six decades.

The Army Corps failed to enact endangered species protections for Willamette River salmon, judge rules

August 19, 2020 — A federal judge has ruled in favor of claims that federally owned dams on the upper Willamette River have failed to carry out Endangered Species Act protections for chinook salmon and steelhead.

U.S. District Judge Marco A. Hernandez ruled Tuesday that the Army Corps of Engineers and the National Marine Fisheries Service (NMFS) fell short of their legal obligations by delaying action or failing to take necessary steps under a 2008 Willamette River Biological Opinion plan. The plan included dozens of measures to ensure the survival and recovery of upper Willamette River wild spring chinook and winter steelhead.

It was a result of a previous lawsuit filed in 2007 by environmental organization Willamette Riverkeeper and Northwest Environmental Defense Center against the Corps for not producing a Biological Plan for the Willamette Basin and failing to comply with the ESA.

Cordova is First to Ask State and Commerce Dept. to Declare Twin Disasters: Fishery and Economic

August 10, 2020 — On Wednesday, August 5, the Cordova City Council unanimously passed a resolution encouraging the state and the federal Secretary of Commerce to declare fisheries disasters for two years: the 2018 Copper River Chinook and sockeye salmon runs and the 2020 Copper River and Prince William Sound Chinook, sockeye and chum salmon runs. The resolution also urges state and federal governments to declare a “condition of economic disaster in Cordova as a result.”

The fishing town of Cordova, located in South-central Alaska between the Copper River to the east and Prince William sound to the west, is the home port for nearly 800 vessels, most of which are the first to harvest returning salmon in Alaska every spring. The town of 2,500 is now the first, of what will likely be at least one or two others, to ask for a fisheries and economic disaster declaration in 2020.
