Low Forecasted Returns For California’s Endangered Chinook Prompts Spring Ocean Fishing Shut Down Off Oregon, California Coasts

With severely low forecasted returns of California Chinook salmon (Sacramento and Klamath River), the National Marine Fisheries Service has cancelled the spring 2023 commercial ocean troll salmon fishery (Cape Falcon to the California border) and the spring recreational ocean salmon fishery (March 15-May 15 from Cape Falcon to Humbug Mountain). This decision was made in consultation with the Pacific Fishery Management Council, and the states of Oregon and California.

UW/NOAA Study Looks At Why Northern Resident Orcas Doing Better Than Southern Residents; They Hunt Differently

In the Pacific Northwest and British Columbia, scientists have been sounding the alarm about the plight of southern resident orcas. Annual counts show that population numbers, already precarious, have fallen back to mid-1970s levels.

California Current Ecosystem Status Report Shows Disconnect Between Oceanographic Predictions, Observed Conditions

Ecological relationships across the Pacific Coast that once guided annual expectations such as salmon returns are evolving as climate change disrupts long-standing connections. NOAA Fisheries researchers report these findings in their latest Ecosystem Status Report for the California Current Ecosystem.

California Salmon: Shrinking Age Distribution Of Returning Spawners Increases Impacts Of A Bad Year, Warming Climate; Older Fish Rarely Observed

By returning to spawn in the Sacramento River at different ages, Chinook salmon lessen the potential impact of a bad year and increase the stability of their population in the face of climate variability, according to a new study by scientists at UC Santa Cruz and NOAA Fisheries.

Low Water, Low Flows Force Columbia River Hydro Managers To Drop Bonneville Dam Tailwater Levels Aimed At Protecting ESA-Listed Chum Salmon

There is so little water available from the upper reaches of the Columbia and Snake rivers that dam operators are dropping the tailwater elevation at Bonneville Dam to 10.2 feet above sea level. That’s a drop of more than 1.5 feet from the minimum tailwater elevation of 11.8 feet required to protect chum salmon nests, or redds, downstream of the dam.

Legislatures Consider Bills To Further Restrict Gillnetters From Lower Columbia River Mainstem; Off-Channel Spring Chinook Fishing Days Approved

Oregon and Washington legislatures are considering bills that would move more commercial gillnetters off the mainstem Columbia River. Washington lawmakers have introduced a bill that would prohibit gillnetting in the mainstem as of January 2025 and it would renew a gillnet license buyback program it began last year that cost about $14 million.

Columbia River Basin Still Only Major Basin In U.S. Free Of Destructive Zebra/Quagga Mussels; Fluctuating Reservoirs May Provide Some Protection

The Columbia River basin in 2023 is still the only major river basin in the U.S. free of quagga and zebra mussels, largely due to the Northwest’s four-state watercraft inspection efforts, according to a presentation this week at the Northwest Power and Conservation Council by Stephen Phillips, senior program manager at the Pacific States Marine Fisheries Commission.

USFWS To Initiate Review Determining If Two Grizzly Bear Populations Should Be De-Listed Under Federal ESA

The U.S. Fish and Wildlife Service has completed the initial review of three petitions filed to remove the grizzly bear in the lower 48 States from the list of endangered and threatened wildlife under the Endangered Species Act in certain ecosystems. The Service says two of these petitions present substantial information indicating the grizzly bears in the Northern Continental Divide Ecosystem and the Greater Yellowstone Ecosystem may qualify as their own distinct population segment and may warrant removal from the ESA list.
