West’s rivers are hot enough to cook salmon to death. Will this court ruling keep them cool? – Bellingham Herald

With global warming comes the heating of our rivers. That has devastating impacts on salmon, which need a river to remain under 56 degrees or young salmon will die. This might bring a change of heart to the issue of Snake River dam removal or breaching.

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.

New Genetic Research Shows the Legacy of Fish Farm – Hakai Magazine

The fish farming industry has been saying for the last number of years that this couldn’t happen. Well, it apparently has. While this could not happen here because of the distinct species, it does add fuel to the fire that these farmed fish are just not a good idea. We have no idea what additional information the industry, along with certain departments in WDFW and NOAA who seem to be simply mouthpieces for the industry, are not investigating, or actually hiding from the public.

Newfoundland’s great fish jailbreak took place on September 18, 2013, when a damaged sea pen, roiled by currents and tides, discharged 20,000 farmed Atlantic salmon into the frigid freedom of Hermitage Bay. Cooke Aquaculture, which owned the failed pen, swiftly set about controlling the damage in the media, if not the ocean. Seals and other predators would scarf up the rogue salmon, the company assured the CBC. The fish, it added, “pose[d] no threat to the environment.” A new genetic analysis, however, refutes that dubious claim. Researchers with Fisheries and Oceans Canada (DFO) have shown that the fish fled Hermitage Bay, fanning out and infiltrating many of southern Newfoundland’s rivers. There, the escapees interbred with their wild cousins—potentially weakening the gene pools of imperiled populations. Ben Goldfarb reports. (Hakai Magazine)

Columbia River salmon fishing closed.

OLYMPIA – Starting Thursday (Sept. 13), fishing for salmon will be closed on the mainstem Columbia River from Buoy 10 upstream to Hwy 395 in Pasco under new rules approved today by fishery managers from Washington and Oregon

Deep River in Washington and other tributaries in Oregon (Youngs Bay, Tongue Point/South Channel, Blind Slough and Knappa Slough) are also closed to salmon and steelhead angling.

The Washington Department of Fish and Wildlife (WDFW) already prohibited steelhead retention in much of the same area of the Columbia River several weeks ago, and the new emergency rule closes angling for both salmon and steelhead in those waters as well.

Bill Tweit, Columbia River fishery coordinator for WDFW, said the counts of fall chinook at Bonneville Dam are 29 percent below preseason forecasts, and on-going fisheries are approaching the allowable catch limits under the Endangered Species Act (ESA). 

“We recognize that this closure is difficult for anglers, but we have an obligation to meet our ESA goals so that fisheries can continue in the future,” he said.

Tweit said the upriver fall chinook run provides the bulk of the harvest opportunity for fall fisheries, but that returns in recent years has been declining due to unfavorable ocean conditions. The preseason forecast for this year is 47 percent of the 10-year average return of upriver bright fall chinook.

The new emergency fishing rule is posted on WDFW’s website at https://fortress.wa.gov/dfw/erules/efishrules/.

PCC Community Markets Ends Sale of Pacific Northwest Chinook Salmon

From the PCC news site

(September 10, 2018) – Seattle-based PCC Community Markets (PCC), the nation’s largest community-owned food market, announced it has stopped selling all chinook (king) salmon products — fresh, frozen and smoked — caught in the waters of Washington, Oregon or British Columbia. PCC is responding to the needs of the critically endangered Salish Sea southern resident killer whales (SRKW) that feed predominantly on area king salmon during the summer.

SRKWs have historically thrived on chinook from the Columbia River, but with the salmon runs at just 10 percent of their original population, the orcas are relying more on salmon from the Fraser River in British Columbia for sustenance. Chinook runs on the Fraser, as well as the Columbia and Sacramento River in northern California, have declined. In sum: SRKWs lack the food they need to survive.

“Last month, the heartbreaking ordeal of the mother orca, Tahlequah, and her baby touched many of our members and staff,” said Brenna Davis, VP of Social and Environmental Responsibility. “In the midst of it, the PCC leadership team began discussing how and if we could make an impact on this issue. By committing to no longer sell Pacific Northwest chinook salmon, we realize that we will not solve the complex set of issues facing our resident orcas. We are simply doing our part as a co-op to ensure, as we have for decades, that our supply chain protects our region’s vital ecosystems.”

Dedicated to protecting local food systems, PCC has long put into place comprehensive efforts to protect the Salish Sea including:

  • Partnerships with Salmon-Safe certified farms, like Wilcox Family Farms. Salmon Safe is a nonprofit devoted to restoring agricultural and urban watersheds so salmon can spawn and thrive;
  • Donating proceeds of sales of Chinook Wines to “Long Live the Kings,” a local non-profit organization that works to protect chinook salmon;
  • Financial support to organizations working to protect marine ecosystems, such as the Duwamish River Cleanup Coalition and Stewardship Partners’ Salmon-Safe certification; and
  • Other efforts including advancing the organic supply chain to keep pesticides and other toxins out of streams, and advocating an end to net-pen fish farms, especially for non-native Atlantic salmon.

In place of Pacific Northwest chinook, PCC will sell Alaskan chinook, which is certified sustainable by the Marine Stewardship Council. PCC also will continue to support local fishers by selling other species of Pacific Northwest salmon.

This website called for a ban on eating locally caught wild chinook over on August 18th.   See “One Orca Two Stories. A way forward?”

In it I stated:

One thought is that if the Chinook fishing is still allowed out off LaPush, and the Orcas have gone there, it must be after the fish. So I’m left wondering, if we really wanted to save starving orcas, why on earth are we allowing recreational fishers to catch 3023 fish? As to the ocean limits, according to state F&W, the ocean recreational limits were:

27,500 fish, which is 17,500 fewer fish than 2017’s quota of 45,000.

So this is approximately 30,000 chinook we are catching when the story of the day is that the Orcas can’t find these fish in the Salish Sea. And this is in addition to whatever the seals and sea lions  have been taking, The studies on seals and sea lions show that they eat primarily juvenile salmon, not as much the older ones! However the study concludes that the seals and sea lions are a problem.

Seattle Chefs Tom Douglas, Thierry Rautureau, Renee Erickson and other major chefs in Seattle have also called for and are implementing a boycott on eating local chinook. This one decision will not immediately put a lot of fish back in the water, but it is clear we are competing with the orcas for their food, and it *will* immediately add to the small amount of Chinook available for them. It will not impact Alaskan Chinook. And  you can also order any of the other salmon that are on the menus or in the stores. So support your local fishermen and eat locally caught salmon other than Chinook. It is OK to dry up demand for local Chinook as a gesture to showing that we need action from our government officials. No more talk!

 

WDFW authorizes transfer of Atlantic salmon into net pens

Note the new location to get future alerts on farmed salmon issues at the bottom of the story.

OLYMPIA – The Washington Department of Fish and Wildlife (WDFW) has authorized Cooke Aquaculture to transport about 800,000 juvenile Atlantic salmon from the company’s hatchery in Rochester, Wash., to existing net-pen facilities in Puget Sound.

WDFW issued the fish transport permit this week after working to ensure Cooke had met all of the state’s requirements for fish health.

Earlier this year, state lawmakers passed legislation to phase out Atlantic salmon net pen operations in Puget Sound as soon as 2022. Cooke is continuing its operations in the meantime.

On Aug. 2, Cooke submitted applications to move a total of 800,000 1-year-old Atlantic salmon from its Scatter Creek facility in Rochester to two different net pen locations in Puget Sound.

Both WDFW and Cooke tested samples of the fish, which met the state’s health requirements, including testing negative for all forms of the fish virus PRV (piscine orthoreovirus), said Ken Warheit, WDFW’s fish health manager.

Cooke typically transports fish eggs from an Iceland facility to Scatter Creek, where the eggs grow into smolts before being moved to net pens. In May, an exotic strain of PRV that shows up in north Atlantic waters was detected in a different batch of smolts at Cooke’s Scatter Creek facility. WDFW denied the company’s request to transfer those fish into net pens.

The state also requires that Cooke leave its net pens empty (or “fallow”) for at least 30 days before transferring fish there. Warheit noted that Cooke will also meet this requirement as it transfers fish in October and November.

Cooke will move about 400,000 juvenile Atlantic salmon to its Cooke’s Hope Island facility in Skagit Bay and another 400,000 fish to its Orchard Rocks facility (Kitsap County) in Rich Passage.

All future notifications about Atlantic salmon transfer permits will be posted online at https://wdfw.wa.gov/ais/salmo_salar/ where people will be able to sign up for email notifications in the near future.

In WSU Stormwater Runoff Research, Coho Salmon Die Quickly,Chum Survive

More data that shows how complicated the salmon recovery effort is.

On April 20, 2018, the Columbia Basin Fish and Wildlife News Bulletin reported that Washington State University (WSU) scientists discovered that different species of salmon have varying reactions to polluted stormwater runoff.

In a recent paper published in the journal Environmental Pollution, scientists found that coho salmon became mortally ill within just a few hours of exposure to polluted stormwater. But chum salmon showed no signs of ill- effects after prolonged exposure to the same water.

The study can be found at

https://www.sciencedirect.com/science/article/pii/S026974911734527X?via%3Dihub

“It really surprised us,” said Jen McIntyre, an assistant professor in WSU’s School of the Environment. “Not that the coho were affected so quickly, but how resistant the chum were. We saw no impact at all in the chum’s post-exposure blood work.”

Stormwater is toxic to fish because it can include carcinogenic hydrocarbons, metals, and other organic compounds, most of which have yet to be identified.

McIntyre and her team collected stormwater runoff in large tanks from a highway in western Washington. Then they placed salmon in that water for four hours or until the fish showed signs of illness. Blood samples were then taken from all of the fish.

Only a few coho lasted four hours before having to be removed. In blood tests, the team found a significant increase in lactic acid concentrations and their blood was much thicker. Their blood pH was thrown off and the amount of salt in their plasma decreased significantly.

The chum test results showed none of those changes, all these fish lasting the full four hours without showing any signs of distress or sickness.

 

“These fish are very closely related,” said McIntyre, who works at WSU’s Puyallup Research and Extension Center. “They’re the same genus, but obviously something is significantly different physiologically. We just don’t know what that difference is yet.”

The study was done at the Suquamish Tribe Grovers Creek Salmon Hatchery, with fish donated by the Suquamish Tribe.

McIntyre worked on the project with fellow WSU scientists, along with colleagues from the National Oceanic and Atmospheric Administration (NOAA) National Marine Fisheries Service and the U.S. Fish and Wildlife Service.

McIntyre and her team noticed a few clues for where to start their next round of investigations: studying what makes the chum nearly impervious to toxic runoff. One is that the coho appeared hypoxic, meaning they weren’t getting enough oxygen. But the water had plenty of oxygen, so they’ll look at blood circulation issues, how the fish metabolize oxygen in their muscles, and a few other areas.

“We don’t know if the thicker blood is a symptom of the problem, or if that’s the initiating event that then causes the oxygen deprivation,” McIntyre said. “There’s a lot of work still to come, but this really narrows down where we need to look.”

They’re also hoping that looking further into chum will turn up clues about how they resist the effects of toxic runoff.

In a later study, not included in this paper, McIntyre and her team conducted a prolonged exposure test on chum. Those fish swam in the stormwater runoff for four days and none of them got sick.

“We’re still trying to understand how they’re unaffected,” she said. “It’s actually really impressive.”

Another problem for the coho is that scientists don’t know what particular contaminants in the runoff are causing the problems.

“There’s a whole variety of heavy metals and hydrocarbons in that water,” McIntyre said. “And a whole bunch of chemicals we are working with scientists at the University of Washington in Tacoma to identify so that we can protect more delicate species like coho salmon from the effects of human pollution.”

McIntyre’s research is part of a grant from EPA.
