#chinooksalmon — Public Fediverse posts

After 3 years of closures that devastated CA's fishing industry, commercial salmon fishing is poised to reopen this spring.

But that doesn't fix the underlying problem as our lead scientist @jarosenfield explains:
"As soon as it stops raining or snowing, we’re going to be back in the same situation with the salmon season closing. If we don't protect river flows and cold water storage, then we’re not protecting salmon."

State officials have a once-in-a-generation chance to save California salmon—and they're failing.

As our lead scientist @jarosenfield stresses in this article, the state's plan would drive native fishes to extinction:

Last week we looked at the Safari Ltd. “catfish” which Safari was kind enough to identify not at the species level, or even family level, but at the order level. An order containing 3,000 species. The figure was pretty easy to identify but it does beg the question, why doesn’t Safari identify it more precisely on their website? They commissioned it after all. Well today we’re looking at […]

A River’s Microbiome May Protect Wild Salmon Against Malnutrition

"Chinook salmon may be canaries in the coal mine by revealing that widespread thiamine deficiency could be quietly chiseling away at fish, bird, and wildlife populations across the northern hemisphere"

For the first time in more than a century(!!), salmon are returning to the Klamath River's headwaters following the completion of a major dam removal project.

A good reminder that nature can rebound if we just let it 🐟

A new plan for California's water would increase the chances that salmon, smelt & steelhead would go #extinct: "Not only do the proposed operations make things no better (for fish in the San Francisco Bay-Delta), they actually make things worse," as our science director @jarosenfield told @CALMatters

'Anything that can be built can be taken down': The largest dam removal in US history is complete – what happens next?

The #KlamathRiver is free of four huge dams for the first time in generations. But for the #Yurok tribe, the river's restoration is only just beginning – starting with 18 billion seeds.

by Lucy Sheriff, September 3, 2024

"This is decades and decades in the making," says Thompson. 'We were told it was never going to happen. That it was foolish to even ask for one removal. We were asking for four.'

"The #KlamathBasin covers more than 12,000 square miles (31,000 sq km) in southern Oregon and northern California, and was home to the JC Boyle, Copco 1, Copco 2 and Iron Gate dams, all owned by #PacifiCorp, an electric utilities company. The Klamath was once the third-largest salmon producing river on the US's West Coast before the construction of the dams blocked fish from accessing almost 400 miles (640km) of critical river habitat for almost 100 years.

"Fall #ChinookSalmon numbers plummeted by more than 90% and spring chinook by 98%. #SteelheadTrout, #CohoSalmon and #PacificLamprey numbers also saw drastic declines, and the Klamath tribes in the upper basin have been without their salmon fishery for a century, since the completion of #Copco 1 in 1922. The situation became so bad that Yurok tribe – who are known as the salmon people – began importing Alaskan salmon for their annual salmon festival, traditionally held to celebrate the first return of fall chinook salmon to the Klamath River.

"The dams also had a severe impact on #WaterTemperature and quality – growth of #ToxicAlgae behind two of the dams resulted in health warnings against water contact.

"'It was painful,' says Willard Carlson, a Yurok elder who is known as a #RiverWarrior and was part of the inter-generational campaign. 'All those years seeing our river damaged like that. I remember as a kid we'd have other people from nearby tribes making fun of our river. 'Oh, you're Yurok, your river is dirty.' For us, the #dams were a monument to the [#coloniser] people who conquered us."

"Restoring the land

But something that does need "a helping hand is the restoration of 2,200 acres (890ha) of land that is above ground for the first time in a century following the emptying of four reservoirs.

"'Removing the dams is one thing, restoring the land is quite another,' says Thompson, a civil engineer and part of the crew working on the restoration project – which is being managed by Resource Environmental Solutions, an ecological restoration company."
