This year’s run of endangered sockeye salmon into the Snake River is “effectively over” and any of the fish crossing Lower Granite Dam after July, the most upriver of the lower four Snake River dams, have almost no chance of reaching the Sawtooth Basin.
Less than two years ago, four dams on the Klamath River were removed. This week, the first peer-reviewed science is out — published in Scientific Reports– confirming that Chinook salmon reoccupied 88% of their historical range within just two migratory seasons. Chinook salmon didn’t just trickle back into reconnected habitat in the upper Klamath Basin….
Traditional field research combined with new technology has revealed a secret to the survival of juvenile salmon as they form in their eggs, especially in low-water years when many do not survive, new research from NOAA Fisheries and the University of California, Davis shows.
Sacramento River winter-run Chinook salmon are California’s most endangered salmon, with a single surviving population and an average of a few thousand returning fish in recent decades. Shasta Dam blocks their original habitat in cold mountain rivers draining Mount Shasta, leaving them to spawn in the low-lying Sacramento River heated by the summer sun.
The Washington Department of Fish and Wildlife recently completed its revised State Wildlife Action Plan (SWAP) , designed to guide fish, wildlife, and habitat conservation in Washington for the next decade. Last updated in 2015, the plan acts as a roadmap for proactive conservation actions that prevent the need to list species under protective regulations…
The Washington Department of Fish and Wildlife, in coordination with the Cowlitz Indian Tribe, U.S. Forest Service, and conservation partners, have reintroduced spring Chinook salmon into the upper North Fork Toutle River watershed within the Mount St. Helens National Volcanic Monument for the first time since the 1980 volcanic eruption. In June, WDFW and project…
Industrial-scale illegal fishing continues to undermine ocean sustainability, coastal livelihoods, and global seafood markets—despite decades of regulation and recent advances in surveillance technology, according to new University of British Columbia (UBC) research.
Wind farms have received heat in recent years for their potential to harm wildlife, a notable issue in western North America where some farms are located near populations of protected bald eagles and golden eagles. A new study published in the Journal of Raptor Research, “Behavioral Responses of Large Soaring Raptors to Audio Deterrents at…
U.S. Sens. Lisa Murkowski (R-AK) and Sheldon Whitehouse (D-RI) have introduced legislation that they say would help the National Oceanic and Atmospheric Administration better assess and protect fisheries.
