Double-crested cormorants will eat many times more salmon and steelhead per bird as a proportion of their diet the farther they are pushed upstream in the Columbia River estuary, according to a presentation this week at the Northwest Power and Conservation Council’s Fish and Wildlife Committee meeting.
For the third straight year, high levels of spill at Columbia and Snake river dams has impacted detection rates of tagged juvenile salmon and steelhead as they migrated downstream through dams.

The growth rate of seafood farming worldwide peaked in 1996, according to new University of British Columbia research, highlighting the importance of rebuilding wild fish stocks to feed future demand.
The world’s current climate pledges are insufficient to keep the goal of the 2015 Paris Agreement firmly within grasp. Global warming will likely surpass the 1.5-degree Celsius limit.
Grant Public Utility District is taking the next step with its partner X-energy to build a modular nuclear power plant in Washington. The utility hopes to have the up-to-320 megawatt 4-unit power plant online by as soon as 2028, according to its chief resource officer Kevin Nordt.
The National Park Service and U.S. Fish & Wildlife Service this week announced the initiation of a new Environmental Impact Statement process to evaluate options for restoring and managing grizzly bears in the North Cascades of Washington, where the animals once thrived.
As climate change worsens water quality and threatens ecosystems, the famous dams of beavers may help lessen the damage.
The National Oceanic and Atmospheric Administration has awarded Oregon State University and its research partners $4.2 million to investigate how multiple climate change-related stressors are impacting marine ecosystems off the coast of Oregon, Washington and Northern California.
The 2023 white sturgeon fishing season gets underway Sunday, Jan. 1, 2023 on select sections of the Columbia River upstream of Bonneville Dam, fishery managers from Oregon and Washington announced Wednesday.
The Bureau of Reclamation began releasing extra water at Grand Coulee Dam over the weekend to ensure that protective flows for spawning chum salmon could begin Tuesday, Nov. 1 at Bonneville Dam, regardless of whether chum were present.
California state scientists have released a new report that shows how the impacts of climate change are rapidly accelerating in California. Key findings illustrate an exponential increase in wildfires and point to a hotter, drier environment driven by megadrought. Climate-influenced changes in freshwater and ocean conditions, says the report, are threatening the survival of Chinook salmon in Northern California rivers.
There is an increase in the number of stranded California sea lions along the entire Oregon coast due to leptospirosis, a naturally-occurring bacteria that can also sicken dogs, people, other wildlife, and livestock.
Just as you might look down at the sidewalk as you walk, fish look downward when they swim, a new study by a Northwestern University-led international collaboration has confirmed.
A UCLA-led study published this week reveals that migratory birds across North America are getting smaller, a change the researchers attribute to the rapidly warming climate.
As marine species continue to decline worldwide, the southern resident killer whale population — which now stands at 75 individuals — along the west coast of North America, has baffled scientists who are trying to understand why this population is struggling.
Conservationists filed a formal notice this week of their intent to sue the U.S. Fish and Wildlife Service for once again denying Montana’s Arctic grayling population Endangered Species Act protections. Arctic grayling is a freshwater fish in the same family (Salmonidae) as salmon, trout, and whitefish.
Faster and more widespread testing for chronic wasting disease in deer is now possible due to a new partnership between the Oregon Veterinary Diagnostic Laboratory at Oregon State University’s Carlson College of Veterinary Medicine and the Oregon Department of Fish and Wildlife.
New research from the University of Oxford, Yellowstone National Park, and Penn State, published this week in the journal Science, may have finally solved why wolves change color across the North American continent.
The U.S. Fish and Wildlife Service has finalized protections for the emperor penguin, a flightless seabird endemic to Antarctica, under the Endangered Species Act. The emperor penguin is listed as a threatened species and includes a section 4(d) rule that tailors protections for the species. The impact of climate change on sea-ice habitat, where the species spends the majority of its life, is the primary threat to the penguin.
Narwhals are changing their migration patterns in response to pressure from changing Arctic climates, a new University of British Columbia report has found.
An international coalition of researchers says in a report published this week that the Earth’s vital signs have worsened to the point that “humanity is unequivocally facing a climate emergency.”
The Center for Biological Diversity and the Audubon Society of Portland filed a formal notice this week of their intent to sue the U.S. Fish and Wildlife Service to better protect the streaked horned lark, a rare bird found in Washington and Oregon.
