Millions have been spent on orca recovery: Is it working? – Everett Herald


And a follow up to the previous story, this is a good layman’s overview of the issue of salmon and orca recovery. It focus’ on Snohomish County but also discusses Sound wide issues. Notice, no mention of hatcheries here. It’s about habitat recovery. This article appears to have come out from under the paywall at this point.

Millions have been spent on orca recovery: Is it working?

Controversy flares up over proposed policy revisions for state salmon hatcheries -PSI

This is a never ending story, because neither the Tribes, the sports & commercial fisheries, nor the politicians of any stripe are willing to entertain what is needed, which is an elimination of most hatcheries. Why? Because science has proven they don’t work. We have had hatcheries since at least the 1940s and they have not helped produce more wild salmon, nor added significantly to anything but sports fishing and farmed at a huge cost to taxpayers. (The exception to this is to protect almost extinct runs for tribal subsistence which is a valid concern for cultural survival of our Tribes. )We once had monstrous runs of wild (and free) fish for anyone to eat that would simply go out and catch them. They provided for lower income people in times of need. We have squandered that resource for many reasons, and have infected many of them with virus’ transmitted through farmed fish. We have spent vast resources trying to produce significant runs in hatcheries. None of this has worked. The science says to end hatcheries, but the political football of this issue just won’t let it go away. The future looks like we will lose our wild salmon in favor of robo-fish, farmed and produced simply for human and animal consumption. We do this at our peril. Just look at what one virus, picine reovirus (https://raincoastresearch.org/salmon-farm-impacts/viruses/piscine-reovirus/) has done to farmed fish stocks around the world.

So with that preamble, here’s today’s story>

A state policy revision that could boost salmon production at fish hatcheries in Washington state has raised red flags among scientists and environmental groups worried about potential damage to wild salmon runs.


The proposed hatchery policy, under review by the Washington Fish and Wildlife Commission, could derail a 20-year effort to implement critical hatchery reforms, opponents argue. Major concerns revolve around threats to the future of wild salmon populations — including declines in genetic diversity and increasing competition from large numbers of hatchery fish. At the same time, a variety of sport and commercial fishing groups have thrown their support to increased hatchery production, saying that policies to protect wild salmon have reduced fishing opportunities while doing little to save wild salmon.

Minor bridge modifications could help young steelhead escape from Hood Canal – PSI

As this blog has reported for many years, the Hood Canal Floating bridge is a barrier likely the primary issue responsible for the massive decline in salmon in the Canal. An unintended consequence of our putting a floating bridge in rather than one that would be a suspension bridge. Chris Dunagan brings us up to speed on the latest work by engineers to address this mistake.


Help could be on the way for migrating steelhead and salmon in Hood Canal, where many young fish are killed each year by seals and other predators that lie in wait at the Hood Canal floating bridge. As many as 50 percent of the steelhead migrants perish as they arrive at the bridge, where predators pick them off one by one. The bridge is supported by floating concrete pontoons, forming a nearly solid barrier across the waterway. Young steelhead generally swim near the surface, making them especially vulnerable to predation, although some fish will dive under the bridge to get to the other side. Engineers are currently designing minor modifications to a few bridge pontoons to help the fish find their way through existing gaps in the structure. Chris Dunagan reports. (Puget Sound Institute)

The Elwha dams are gone and chinook are surging back, but why are so few reaching the upper river? – Seattle Times

Good update on the return of the river.


They were the king of kings in Puget Sound, the biggest chinook of them all, strong enough to muscle up the falls at the Goblin Gates and power on all the way through nearly 4 miles of chutes and falls in the Grand Canyon of the Elwha….Scientists have been tracking nature’s response. Some of what they are finding is surprising, even to them. Summer steelhead, nearly extinct in the Elwha, have come booming back to the river, all on their own. Once locked up behind the dams, rainbow trout are re-expressing their ability to go to sea as steelhead. Adult chinook returns to the river since dam removal are the highest since the late 1980s, with more than 7,600 estimated in the 2019 count. While that’s still a modest number, the Elwha represents one of the only watersheds in Puget Sound with such an uptick in population, said Sam Brenkman, chief fisheries biologist for the Olympic National Park, in an email. Colonization of the lower and middle river has been steady. But fewer chinook are reaching the deliciously cold, uppermost reaches of the watershed. Why? It’s a puzzle scientists are working on. Lynda Mapes reports. (Seattle Times)

Blueback closure latest in Quinault climate change impacts – North Coast News

And as if to put a fine point on the previous article, commercial fishing is being closed on the Quinault River for sockeye.  If I’m not mistaken, while the Quinault is not dammed, it has been greatly affected by widespread logging of the hills all around it. A look at the satellite images of the river from Google Earth https://earth.app.goo.gl/uDneeP shows that between currently logged areas and second and third growth areas the habitat for salmon has been seriously compromised over the last 100 years. The buffers along the river, likely clear cut long ago, have been allowed to grow back and gain some modicum of protection for the river, but appear to be very small, compared the vast logging operations allowed all around it. Take a look and explore the overview of the area. Likely the increased temperatures from global warming, overharvest at sea, sea water warming and the increasing upflows of cold water known as the “Blob” have all added to the problems.  Have a different opinion on what’s causing all this? Feel free to add them to the comments below. I don’t claim to know it all, just cursory looks and 40 years seeing the endless logging of the west end proceed with virtually no stopping nor real effort to protect the watersheds which are the habitat of the salmon that spawn there.

The decision to close commercial fishing for Quinault River blueback (sockeye) salmon for conservation purposes this year is part of the ongoing effort by the Quinault Indian Nation to deal with the very tangible costs of climate change. After announcing the blueback closure on the river last week for 2019, Quinault President Fawn Sharp traveled to Washington, D.C. with a message for Congress about how the entire Quinault ecosystem from the glacier to the ocean is being harmed by climate conditions that have major impacts, economically as well as environmentally. Angelo Bruscas reports. (North Coast News)

BC Led international expedition to probe ailing Pacific Salmon stocks- Vancouver Sun

Finally we are seeing some joint scientific effort around wild salmon. Time is certainly running out to take dramatic steps to save what is left of the salmon runs. Glad to see this happening now, no matter how late in the day it seems.

An unprecedented international collaboration could revolutionize salmon science and fisheries management, return forecasting and even hatchery output. Nineteen scientists from Russia, Canada, the United States, Japan and South Korea are set to probe the secret lives of five Pacific salmon species with a four-week grid search and test fishery across the Gulf of Alaska. The expedition begins next week aboard the Russian research ship MV Professor Kaganovsky. “We know virtually nothing about what happens to salmon once they leave near-shore waters in the Salish Sea,” said expedition organizer Dick Beamish. The project was developed as a research element of the 2019 International Year of the Salmon celebration, organized by the North Pacific Anadromous Fish Commission and its partners.

State discusses killing seals and sea lions in Puget Sound

Perhaps the most controversial idea out of the Orca task force has been the notion of killing sea lions and seals to help salmon survive. Like many ideas, this one is simplistic and has the greatest appeal to people who don’t want to spend much time thinking about whether something works or just makes you feel like you are doing something. Fish and Wildlife are holding meetings to gather information on whether or not this really is an idea with merit. Biologists who study the food chain aren’t so sure. If you think you already know the answer, then you should read this article. “There is no guarantee of a response by the salmon in terms of returning adults.” And you know what an assumption is, it’s a word made up of and makes an “ass of u and me”. Let’s put the science of this in it’s rightful place, which is at the head of the train and not tow it along in our ill informed wake.

State wildlife commissioners heard testimony Friday about whether a seal and sea lion cull could help save salmon, and thereby restore food to the starving Southern Resident killer whales (SRKW)…. “It’s important to set the stage that this occurs in a very complex ecosystem and it is a very complex food web,” said WDFW Research Scientist Scott Pearson…. “If you want a 25 percent reduction in the total juvenile Chinook consumption by seals, we have to reduce this number of 19,000 seals down to 14,300. If you subtract this number from this number, that’s how many we have to remove 4,700 seals, and we have to annually remove 530 seals per year to keep it at that level,” Pearson said. But the problem is, salmon also face a slew of other challenges, including hydropower, hatcheries, habitat, disease, and contaminants. Scientists told commissioners they don’t know whether killing seals and sea lions will do anything at all…. “In my opinion, even if the seal consumption were somehow reduced or eliminated, there is no guarantee of a response by the salmon in terms of returning adults,” said WDFW Research Scientist Joe Anderson.

Congress OKs bill to allow killing sea lions to help salmon – Seattle Times

The knee jerk reaction to killing sea lions to theoretically ease the amount of endangered salmon that are being eaten by them passed Congress two days ago. While not based in science, this has been done at the behest of a variety of groups that see the sea lions as the problem. White sports fishermen, some tribes. The likelihood of this succeeding in any meaningful way has not been proven. But killing something always seems like a good solution to many.

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/.

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.

Dismal Copper River salmon run prompts ‘unprecedented’ shutdown of dip-netting at Chitina – Anchorage Daily News

Not good news coming in from the Copper River. Salmon numbers are so bad they’ve close the fishery.

The state is taking the historic action of shutting down Copper River dipnetting at the popular, physically demanding sites around Chitina.

The Alaska Department of Fish and Game issued an emergency order Wednesday closing the personal-use fishery until further notice as of Monday.

New ways of fishing could better protect endangered salmon – Watching Our Waterways

Another good idea to explore for saving salmon.  Could be used in some trial scenarios. From many non-native fishermen I’ve talked to, the issue for them will likely be management of the native part of the take. There is a wide spread perception that the tribal take is not well managed and that they get to take more with less oversight, while the non-native fisherman is overburdened with regulations and enforcement. It’s been expressed to me that all many fishermen want is equal balance to the catch. While I’ve done a lot of looking into this issue and do not feel that the non-native perspective is accurate, the state and tribes might want to do a better job of PR to the non native community to help explain how it’s done.

Higher standards of “sustainability” for salmon — recently developed by the Wild Fish Conservancy — are designed to put salmon on people’s tables with virtually no impact on depleted salmon runs. The new standards, which could become part of a certification program, are built upon the concept that fishing should take place closer to streams with abundant runs of salmon. The standards call for fishing methods that can take a portion of the fish from the abundant runs while allowing fish from depleted runs to pass on by and spawn naturally. Chris Dunagan reports.

Sea lions feast on fragile fish in US Northwest survival war – AP

This is a major problem, and one that pits one creature against the other as we watch the stocks of salmon continue to decline. Sea lions aren’t the *only* issue facing salmon, (which include habitat destruction, over fishing and more) but given the low numbers of fish, they have become a major problem for their survival. The question it raises is do we kill off sea lions to save the salmon? If so, how many?

It’s a frustrating dance between California sea lions and wildlife managers that’s become all too familiar in recent months. The bizarre survival war has intensified recently as the sea lion population rebounds and fish populations decline in the Pacific Northwest Gillian Flaccus reports.(Associated Press)

What’s killing the salmon? Long Live the Kings investigates decline in iconic fish – KCPQ

Good overview of what Long Live The Kings and Microsoft are doing to help us understand root causes of the decline of the salmon.

Salmon are a big part of life in the Pacific Northwest. But over the past couple of decades, they’ve declined to critical levels and researchers don’t know why. Solving the mystery is what nonprofit Long Live the Kings is working on, and thanks to a grant from Microsoft, technology is helping the nonprofit develop a comprehensive model to find clues to solve it. Long Live the Kings is looking into Puget Sound and the waterways the flow into it, more broadly known as the Salish Sea. This Salish Sea Marine Survival Project is tracking migration of fish through our marine environment to understand what’s affecting salmons’ mortality.  Simply, why do salmon keep dying?

Pesticides and salmon: Can we see a light at the end of the tunnel? – Watching Our Water Ways

Once again, the National Marine Fisheries Service has determined in official findings that three common pesticides — chlorpyrifos, diazinon and malathion — raise the risk of extinction for threatened and endangered salmon. By extension, for the first time, the agency also concluded that those same pesticides threaten Puget Sound’s endangered orca population by putting their prey — chinook and other salmon — at risk. This politically and legally charged issue — which has been around for more than 15 years — has gone beyond a debate over potential harm from pesticides. It also raises uncomfortable questions about whether our society will follow science as we try to solve environmental problems. Chris Dunagan reports. (Watching Our Water Ways)

Salmon fishing restrictions may get ‘severe’ – KING

It appears that we are going to need to take more draconian steps to save the remaining Chinook. While no one wants to see salmon fishing undergo more restrictions, it’s better than not having any of the fish left here. California already is in that situation.

A salmon fishing agreement between the Washington State Department of Fish and Wildlife and tribal co-managers is fueling continued angst by many recreational fishermen who fear it will force severe closures. The Comprehensive Management Plan for Puget Sound Chinook was recently released after a long secret court mediation process. If approved, it could place severe restrictions on salmon fishing around Puget Sound. Because the plan was reached in secret, it’s also reignited a rallying cry for transparency from WDFW and tribal co-managers…. Both the Attorney General’s office and representatives from WDFW explained that the mediation process required non-disclosure from all parties. If approved by NOAA, the plan would reduce the exploitation rate from 12 percent to 8 percent on wild Chinook for the next 10 years. That means only 8 percent of the wild Chinook expected to return to their natal streams can be impacted by fishing. Alison Morrow reports/ (KING)
