Fish, Oceans, Ice, Sealife, & Water News

The Fish News has been stretching into Fish & River News, now into covering Water Issues generally. We cover water as it stands, pools, flows, freezes, and precipitates. A step further, we cover how water affects the things that most directly depend on it, the things that grow, swim, drink, ship, & store water.

Pacific Salmon Going Down Hard

Some Pacific salmon populations are especially at risk from climate change,
PLOS, July 24, 2019.


Climate Change Vulnerable
"Four population groups of Pacific salmon in California, Oregon, and Idaho are especially vulnerable to climate change..."

US Coastal Waters
"To better understand the vulnerability of Pacific salmon, the authors studied 33 threatened or endangered population groups of Pacific salmon, encompassing local populations from the Mexican border to the Canadian border."

University of California - Santa Barbara, February 28, 2019.


Massive Fish Study
“...study looked at historical abundance data for 124 species in 38 regions, which represents roughly one-third of the reported global catch. The researchers compared this data to records of ocean temperature and found that 8 percent of populations were significantly negatively impacted by warming, while 4 percent saw positive impacts. Overall, though, the losses outweigh the gains.”

FISH NEWS: End of Spring-Run Chinook Draws Near


No Genetic Reserve in Fall-Run Salmon Populations

Human actions impact wild salmon's ability to evolve,
University of California - Davis, December 4, 2018.


Near Extinction
“...spring-run chinook are on the brink of extinction in most locations where they haven't already been lost.”

Sensitive to Everything Human
"...because they rely on clean, cold water throughout hot summer months, spring-run chinook are more vulnerable than fall-run chinook" to activities such as logging, mining, dams and water diversion, and to climate change.”

“Once spring-run chinook salmon disappear, they are not likely to re-emerge, indicates genetic analysis of the revered wild fish in a study led by the University of California, Davis.”

"If you lose the spring-run gene, you could potentially lose spring-run chinook forever.”

Fish Rapidly Shifting Ranges following Rapid Temp Changes


Fish Rapidly Shifting Ranges following Rapid Temp Changes

Warming waters caused rapid -- and opposite -- shifts in connected marine communities,
Cell Press, November 8. 2018.


"Two connected marine ecosystems--the Eastern English Channel and Southern North Sea--experienced big and opposite changes in their fish communities over a 30-year period”

“Rapid warming drove smaller ocean fishes to shift abruptly northward from one ecosystem to the other."

Warming Disrupting Fishing Grounds
“...increase in the frequency and severity of climate oscillations and extreme warming events could trigger shifts in the distribution and abundance of species with profound consequences for the way ecosystems around the world function.”

"This warming caused an abrupt change in fish communities as small, rapidly maturing fishes, particularly pelagic fishes, simultaneously decreased in the English Channel and increased in the North Sea,."

Court Ruling to Preserve the Last of the Salmon?


Preserving the Last of the Salmon?

West’s rivers are hot enough to cook salmon to death. Will this court ruling keep them cool?
Sac Bee, October 23, 2018.


River-Cooked Salmon
"...salmon being cooked to death by the thousands in rivers that have become overheated as water flows dwindle."

Stop Cooking Salmon
"...a federal judge in Seattle has directed the Environmental Protection Agency, in a ruling with implications for California and the Pacific Northwest, to find a way to keep river waters cool."

"...ruling last week was sparked by an ecological catastrophe in 2015, when an estimated 250,000 sockeye salmon died on the Columbia and Snake because the waters got too warm. In California, more than 95 percent of juvenile winter-run Chinook salmon perished in the Sacramento River in 2014 and 2015 when temperatures spiked during the worst of the drought."

“...it must develop a plan to keep water temperatures low in the Columbia River and its main tributary, the Snake, to protect multiple varieties of salmon and steelhead that are covered by the Endangered Species Act.”

2018: The Long, Steady, Decline in Salmon Populations Continues


The Long, Steady, Decline in Salmon Populations Continues

Threatened spring-run chinook salmon are sparse this year,
Chico Enterprise-Record, September 26, 2018.

Main Points

"In Butte Creek, a snorkel survey counted 2,118 fish this year."

"That’s less than half the average since 1989 of 4,427 fish."

"In 2017, only 950 fish were counted."

"The record was in 2001, when the carcass survey turned up 18,312 fish."

The carcass survey

"As a result of the lifecycle, the creeks are full of dead fish after the spawning cycle ends."

"The dead fish are also easy to count."

"...in years when there are a lot of fish, the carcass count is far more accurate than the snorkel count. But in a low year like this one, the snorkel count is probably pretty accurate."

Fish History

"The spring-run used to be the largest of the chinook runs in the Central Valley. But construction of dams like Shasta and Oroville blocked access to the higher-elevation cool water the fish need to survive the summer, and the numbers dropped."

"The spring-run is now listed as threatened on both the state and federal endangered species lists."

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

If you feel these efforts are valuable, I'm cordially inviting you to support them, here:



I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
