Genetic Analysis Shows Beluga Whale in Puget Sound Likely Arrived from Arctic Waters

October 26, 2021 — Scientists have collected genetic material from the beluga whale that was first sighted in Puget Sound in early October. It indicates that the whale is likely from a large population of beluga whales in the Beaufort Sea, part of the Arctic Ocean north of Alaska.

The whale appears to have traveled thousands of miles south around Alaska through the Bering Sea and south to Puget Sound. It was last sighted on October 20 near Tacoma. The whale does not appear to be from the small and endangered Cook Inlet beluga population near Anchorage, Alaska.

The genetic analysis involved sequencing DNA extracted from a water sample collected near the beluga whale in Puget Sound earlier this month. This material is known as environmental DNA, or eDNA, because it comes from skin, fecal, or other cellular debris found in the environment near the animal.

WASHINGTON: Puget Sound tribe uses aquaculture to counter salmon shortages

October 18, 2021 — A new video from the Washington Policy Center (WPC) highlights the efforts of the Jamestown S’Klallam Tribe in the Puget Sound area to develop an aquaculture program to provide economic opportunity and a food source for its community.

“As we work to restore the salmon population in Puget Sound, tribes are finding creative ways to feed their members and become more self-sufficient,” said Todd Myers, environmental director at the WPC. “Tribes have the local control and flexibility that allows them to follow good science to manage aquaculture that is sustainable and provides good food.”

The late Kurt Grinnell, who was a tribal council member and general manager of the aquaculture program, explains in the video that just a few generations ago the local rivers and tributaries were filled with an unending supply of salmon. It got to the point though, that he shut down his fishing business because he was catching so few fish that selling them did not bring in enough money to even pay for the gas for his boat.

Navy steams ahead with sonar testing despite state opposition, orca impacts

October 4, 2021 — Over the objections of Washington state officials and orca advocates, the U.S. Navy is steaming ahead with a plan for seven more years of testing sonar and explosives in waters off the Northwest coast.

The Navy says the piercing noise from its tests and training activities could harm eight species of whales listed under the Endangered Species Act.

But Navy officials, backed up by the National Marine Fisheries Service, say the occasional, temporary disturbances won’t threaten the orcas’ or any other species’ survival.

“At this time the Navy intends to proceed over the objection of the State of Washington,” the Navy’s Record of Decision document, published Friday, states.

Low oxygen levels along Pacific Northwest coast a ‘silent’ climate change crisis

September 29, 2021 — Nearly two decades ago, fishers discovered an odd occurrence off the coast of Oregon. They were pulling up pots of dead or lethargic crabs.

At first they suspected a chemical spill or a red tide. But instead, they learned, dangerously low levels of dissolved oxygen in the ocean water were to blame.

The crabs had suffocated.

These swaths of hypoxic areas have surfaced every summer on Pacific Northwest shores since it was first recorded in 2002. They are spurred by naturally occurring coastal upwellings and algae blooms, exacerbated by climate change, said Francis Chan, director of the Cooperative Institute for Marine Resources Studies at Oregon State University.

Akin to fire season, hypoxia season arrived earlier this year – the earliest start in 20 years, according to Chan. But unlike wildfire, or other visible climate emergencies, it’s gone largely unrecognized.

“It’s kind of a silent problem happening out there,” said Chan. “This year, I can look out and see trees with one side burnt because of the heat wave. As I’m driving on McKenzie highway, I can see Mount Jefferson has no snow on it. But when you drive out to the ocean, it looks exactly the same as last summer.”

Learning from gorillas to save killer whales

November 9, 2018 — In 2018, the southern resident killer whale population in the Pacific Northwest’s Salish Sea was at its lowest ever. The world watched in September as an orca named Scarlet, or J50, wasted away and died, leaving just 74 of her kind left. Some wondered if this was “What extinction looks like.”

Meanwhile, endangered mountain gorillas in Africa hit a milestone in the opposite direction. Their population climbed to more than 1,000—the highest in nearly a century.

Building on work begun by primatologist Dian Fossey of Gorillas in the Mist fame, Gorilla Doctors, a program led by the University of California, Davis, has been providing personalized veterinary care to these animals in the wild since the late 2000s. The gorillas have their own long-term health records, and the international team of veterinarians that observe and treat them know each one as they would their own family members and friends—down to the individual.

Judge rules EPA must protect salmon from rising water temperatures in Washington

October 29, 2018 — A U.S. Federal Court in Seattle, Washington, U.S.A. has issued a ruling that is intended to protect salmon and steelhead trout in the Columbia River basin from rising water temperatures.

In the mile-long lakes created by hydropower dams on the rivers, the water temperature has often exceeded 70 degrees Fahrenheit for days at a time, though the Clean Water Act bars the temperature in the river from exceeding 68 degrees. Cold water species such as sockeye and steelhead become stressed at temperatures over 68 degrees and stop migrating when the temperature exceeds 74 degrees.

The ruling instructs the Environmental Protection Agency to protect the species. The EPA will, within 60 days, come up with a “comprehensive plan to deal with dams’ impact on water temperature and salmon survival,” according to Columbia Riverkeeper Executive Director Brett VandenHeuvel, one of the plaintiffs of the case, which was initially filed in February 2017. Other conservation and fishermens’ groups were plaintiffs in the suit as well: Idaho Rivers United, Pacific Coast Federation of Fishermen’s Associations, Snake River Waterkeeper, and The Institute for Fisheries Resources.

Environmental groups sue U.S. Army Corps over Willamette dams, say salmon and steelhead at risk of extinction

March 14, 2018 — Three environmental groups followed through on a threat to sue the federal government Tuesday over the decline in wild salmon and steelhead in the Upper Willamette watershed.

The groups say the U.S. Army Corps of Engineers and National Marine Fisheries Service have failed to take required steps to improve conditions for the threatened fish.

The lawsuit targets the Willamette watershed’s system of dams and its negative impact on fish habitat.

“Federal dam operators in the Willamette River basin must act now to protect our native fish,” said Mark Sherwood, executive director of the Native Fish Society.

The lawsuit is derived from a legal agreement, called the Biological Opinion, issued in 2008, that essentially requires the Corps to modify dams to improve fish habitat.

Fishin’ Company leading MSC certification effort for Oregon’s Dungeness crab fishery

March 14, 2018 — An agreement between the Oregon Dungeness Crab Commission and The Fishin’ Company will pave the way for the Dungeness crab fishery in Oregon to seek Marine Stewardship Council certification.

The memorandum of agreement signed on 7 March will see The Fishin’ Company, a Munhall, Pennsylvania, U.S.A.-based  company that is a major buyer of the crab, provide financial resources and personnel to work alongside the fishery as it enters the MSC pre-assessment process.

“The Oregon Dungeness crab fishery is committed to a sustainable fishery through proven methods of management,” The Fishin’ Company Director of Sustainability Justin Baugh said. “They are focused on continuous improvement through science-based research and we believe the ODCC should be recognized for this and are excited to place our support behind them.”

West Coast Waters Returning to Normal; Some Fisheries Remain Disrupted

March 13, 2018 — SEAFOOD NEWS — Ocean conditions off most of the U.S. West Coast are returning roughly to average, after an extreme marine heat wave from about 2014 to 2016 disrupted the California Current Ecosystem and shifted many species beyond their traditional range, according to a new report from NOAA Fisheries’ two marine laboratories on the West Coast. Some warm waters remain off the Pacific Northwest, however.

The Southwest Fisheries Science Center and Northwest Fisheries Science Center presented their annual “California Current Ecosystem Status Report” to the Pacific Fishery Management Council at the Council’s meeting in Rohnert Park, Calif., on Friday, March 9. The California Current encompasses the entire West Coast marine ecosystem, and the report informs the Council about conditions and trends in the ecosystem that may affect marine species and fishing in the coming year.

“The report gives us an important glimpse at what the science is saying about the species and resources that we manage and rely on in terms of our West Coast economy,” Council Chairman Phil Anderson, of Westport, Wash., said in a press release. “The point is that we want to be as informed as we can be when we make decisions that affect those species, and this report helps us do that.”

Unusually warm ocean temperatures, referred to as “the Blob,” encompassed much of the West Coast beginning about 2014, combining with an especially strong El Nino pattern in 2015. The warm conditions have now waned, although some after-effects remain.

Warmer waters were blamed for increased growth of Pseudo nitzschia, which produces domoic acid. The domoic acid interrupted several fisheries, including Dungeness crab, rock crab and spiny lobster.

This Is Why You Don’t See People-Size Salmon Anymore

March 13, 2018 — While the orcas of Puget Sound are sliding toward extinction, orcas farther north have been expanding their numbers. Their burgeoning hunger for big fish may be causing the killer whales’ main prey, Chinook salmon, to shrink up and down the West Coast.

Chinook salmon are also known as kings: the biggest of all salmon. They used to grow so enormous that it’s hard to believe the old photos now. Fishermen stand next to Chinooks almost as tall as they are, sometimes weighing 100 pounds or more.

“This has been a season of unusually large fish, and many weighing from 60 to 70 pounds have been taken,” The Oregonian reported in 1895.

Now, more than a century later, “it’s not impossible that we see individuals of that size today, but it’s much, much rarer,” University of Washington research scientist Jan Ohlberger says.

Ohlberger has been tracking the downsizing of salmon in recent decades, but salmon have been shrinking in numbers and in size for a long time. A century’s worth of dam-building, overfishing, habitat loss and replacement by hatchery fish cut the size of the average Chinook in half, studies in the 1980s and 1990s found.

Dam-building and fishing have tailed off, but Chinooks have been shrinking even faster in the past 15 years, according to a new paper by Ohlberger and colleagues in the journal Fish and Fisheries. Older and bigger fish are mostly gone.
