Older Chinook salmon may die in the ocean more often than previously thought, according to a life cycle simulation created by Alaska researchers.
As the climate warms and more and more cascading streams dry up, changing those streams to disconnected puddles that trap migrating juvenile salmon and steelhead, humans may have to step in to rescue the fish. Without this intervention, some stocks may go extinct, according to a recent study.
NOAA Fisheries is looking into whether Southern Oregon and Northern California coastal spring/fall chinook salmon should be separated, recognizing spring and fall chinook from the Klamath River basin as two separate species.
U.S. Environmental Protection Agency Administrator Michael S. Regan this week announced his decision to reestablish the membership of the Science Advisory Board (SAB) and the Clean Air Scientific Advisory Committee (CASAC), and reorient the SAB standing committees.
Juvenile salmon run the gamut of predators – birds, other fish and pinnipeds – as they migrate from their rearing grounds far upstream in the Columbia River basin all the way to the ocean, but they also are confronted with predators as they enter the ocean.
The Interior Department last week took steps “to recommit to scientific integrity and empower the agency’s scientific and technical experts to use the best available science.”
The diversity and numbers of wild salmon in Northern B.C. have declined approximately 70 percent over the past century, according to a new Simon Fraser University study.
Scientists at Oregon State University and the U.S. Forest Service have demonstrated that DNA extracted from water samples from rivers across Oregon and Northern California can be used to estimate genetic diversity of Pacific salmon and trout.
An Oregon State University-led project to build the nation’s first pre-permitted wave energy testing facility cleared a critical hurdle this week as the federal Bureau of Ocean Energy Management awarded the university a lease to operate in federal waters about seven miles off the Oregon Coast.
