Deglaciation could increase salmon habitat by nearly 30% in the Gulf of Alaska by 2100.
On Dec. 8 and 9, U.S. Sens. Lisa Murkowski and Dan Sullivan and Rep. Don Young held a Zoom meeting between salmon researchers, tribes, and managers. Their goal was to unite these groups’ efforts to determine the cause of the ongoing Chinook declines and the sudden chum crash in Western Alaska. After two days of meetings, the groups are still at odds over what’s causing the declines, and what the best way to move forward is.
Fish Factor: The summer setline survey could result in increased catches for most regions in 2022.
Salmon abundance is down and population distributions have changed, according to NOAA’s 2021 surface trawl survey.
Multiple fish populations in the Bering Sea have experienced a slight decline, according to the 2021 Bottom Trawl survey.
Drought and extreme heat that scientists link to climate change are altering the UNESCO-protected marshlands. Iraq's average annual temperatures are increasing at nearly double the rate of Earth's.
For the past 5-6 years, salmon runs all over Bristol Bay have been very strong.“This year’s record-breaking return is the result of this careful stewardship,” said executive director of United Tribes of Bristol Bay. “Our lands and waters must be protected so future generations can continue our way of life and Bristol Bay can remain the salmon stronghold for the planet.”
Scientific American is the essential guide to the most awe-inspiring advances in science and technology, explaining how they change our understanding of the world and shape our lives.
Thick-billed murres are feeling the heat from climate change — more so than other Arctic species, new research has found. The black-plumed Arctic seabirds nest for hours on exposed cliffs, making them particularly vulnerable to sun and warming temperatures, according to Emily Choy, a McGill University biologist. Choy’s research focused on a colony of murres
One common salmon virus introduced to southern B.C. 30 years ago despite assertions from government, industry virus is 'endemic' to province. Further analysis of the PRV genomes in B.C. waters indicate that the number of PRV infections in the region has increased by two orders of magnitude over the last two decades, a pattern that aligns with the regional growth in farms, where nearly all of the fish become infected.
Evidence shows a debilitating virus found in British Columbia salmon was transferred from Atlantic fish farms, which then spread from Pacific aquaculture operations into wild fish, says a study published Wednesday.
The tiny fishing fleet from St. Paul is losing the fight for halibut, up against factory ships that throw away more of the valuable fish than the Indigenous fishers are allowed to catch.
Warming waters have driven thousands of ocean species poleward from the equator, threatening marine ecosystems and the livelihoods of people who depend on them.
Plastic pollution is threatening the wildlife in the Mekong River Basin.
Researchers observe declines in sockeye salmon diversity of the Skeena River, British Columbia. Populations that have returned to their spawning grounds for years are at risk of dying out.
William Twardek, a Carleton University PhD student who's been studying Yukon River chinook salmon, says his four-year research project has found that some fish simply can't make it past the fish ladder to reach their spawning grounds.
A meeting of the Yukon River Panel focused on a surprising discrepancy between measurements at two different sonar stations. This could mean fish are dying or being miscounted, or that harvesting is going unreported.
A new report from the Governor's Salmon Recovery Office shows salmon and steelhead populations in Washington state teetering on the brink of extinction. Five or the populations of salmon and steelhead listed a threatened or endangered, are in crisis.
January 15, 2021 - Following a summer and fall of cloudy waters in Great Slave Lake and the Hay and Slave Rivers, the Department of Environment and Natural Resources (ENR)...
Bocaccio rockfish have made a huge comeback in B.C. since being deemed endangered in 2013, but the success story is being met with some trepidation as trawler fishermen can’t seem to avoid netting them now.
