Washington taking comment on permits for Atlantic salmon fish farms

January 4, 2019 — The state Department of Ecology is taking comment now on permits for four Cooke Aquaculture Atlantic salmon farms — three in Kitsap County and one in Skagit Bay.

Farming Atlantic salmon in net pens is officially banned from Puget Sound starting in 2022.

Ecology is using the investigation from the 2017 Cypress Island net pen collapse to mandate more protective permit requirements.

Cooke Aquaculture, the only company farming Atlantic salmon in Washington state, lost its lease in Port Angeles in 2017.

Ecology is accepting comments on the permit through Feb. 25 and will make a final determination after reviewing them.

Why Does Halibut Cost So Much?

January 4, 2019 — Dishes fly across the galley. Water gushes through the scuppers and onto the deck. Five crew members on the 17.5-meter commercial halibut boat Borealis Iwalk like drunkards, holding onto anything stable. “We’re going to get bounced around a bit,” Dave Boyes, the boat’s captain and owner, deadpans.

My day started at first light, about six hours ago, watching the crew let out 2,200 galvanized circle hooks laced with chunks of pollock, squid, and pink salmon to soak across 13 kilometers of ocean bottom. Then, we ate breakfast and rested in cramped, cluttered bunks while the boat bounced on 1.5-meter waves and—below, in the cold unseen depths—the hooks sunk deep into the lips of the predatory halibut.

Now, the crew readies for battle, cinching rubber rain gear and running crude gutting knives across electric sharpeners—a portent of the bloodshed to come. When Boyes toots the boat’s horn, it’s game on.

My love of halibut got me here—in Hecate Strait, off northern British Columbia—as did my disdain for the price. Salmon are held up as the iconic symbol of the Pacific Northwest, but the way I see it, halibut is king, offering superior flavor and texture. When I can afford it, I serve the white fish baked with a glaze of butter, mayonnaise, and whole grain Dijon mustard.

During a summer visit to my local fish shop—Mad Dog Crabs in the Cowichan Valley of Vancouver Island—fresh halibut fillets sold for CAN $6.38 per 100 grams, compared with $5.28 for sablefish and $3.74 for sockeye salmon. “It’s the prime rib of the sea,” explained fishmonger Scott Mahon, who fished commercially for over 20 years. “Better taste, better quality, and better shelf life.” Unlike the farmed salmon industry, halibut aquaculture remains a relatively nascent enterprise and does not offer a less-expensive alternative to consumers.

OSU scientist studies slimy new way to count salmon

January 3, 2019 — Scientists have published a novel method for counting Pacific salmon – analyzing DNA from the slime the fish leave behind in their spawning streams.

The study, funded by The National Geographic Society, is published in the journal Molecular Ecology Resources.

“When we analyzed the environmental DNA sloughed into water from salmon tissues, including mucus and skin cells, we got very accurate counts,” said Taal Levi, an ecologist at Oregon State University and lead author on the study. “This is a major first step for more informed salmon management decisions because it opens up the possibility to affordably monitor many more streams than the few that are currently monitored.”

Pacific salmon are a keystone resource in the Pacific Northwest, with an economic impact of well over $500 million each year in Alaska alone. Currently, spawning salmon are counted at just a few streams due to the reliance on human counters, or in rare cases, sonar. Five species of Pacific salmon – pink, chum, sockeye, coho, and chinook – are distributed through more than 6,000 streams in southeast Alaska alone. More than 1,000 of those streams host spawning salmon.

Salmon are anadromous: They migrate from home streams to the ocean as juveniles, and return a few years later as adults to spawn. Anadromous fish such as salmon provide a straightforward scenario for testing whether environmental DNA (eDNA) can be used to count fish, because large numbers of salmon release their DNA as they pass a fixed sampling point, either as they swim up a river or stream as inbound adults or swim downstream as outbound juveniles.

In many rivers and streams, including the majority of freshwater systems in Alaska, adult salmon returning to spawn are poorly monitored, as are fry and smolt production resulting from spawning salmon.

For the study, researchers collected water samples in 2015 and 2016 near the Auke Creek research weir, nearly 16 kilometers north of Juneau. Weirs consist of a series of closely spaced bars across an entire stream to prevent the passage of salmon, except through a single, narrow gate over which a human observer tallies and identifies salmon as they file through.

The Auke Creek weir, cooperatively operated by the National Marine Fisheries Service, in collaboration with the University of Alaska and the Alaska Department of Fish and Game, is known as one of the most accurate fish counters in the world, Levi said.

Alaska Department of Fish and Game Releases New Pacific Salmon Treaty Language: New Provisions Go into Effect Tomorrow

January 2, 2019 — The following was released by the Alaska Department of Fish and Game:

With implementation poised to begin January 1, the Alaska Department of Fish and Game today released three chapters of new Pacific Salmon Treaty language. These three chapters will directly impact Alaska and Alaskans.

The current chapters of the Pacific Salmon Treaty that affect southeast Alaska expire December 31, 2018. Over the past several years a team of 58 Alaskans including department staff and affected users have been working towards negotiating a new agreement. In June 2018 the Pacific Salmon Commission completed negotiations regarding a new conservation and harvest sharing agreement between the United States and Canada. This new agreement forms the basis for management of southeast Alaska salmon fisheries.

The negotiated treaty language has been held in confidence for a variety of reasons. However, since the revised treaty takes effect January 1, 2019, releasing the latest version of the agreed to treaty language is in the best interest of affected users. It is important to understand that the treaty language is not open to renegotiation as it has been agreed upon formally. The release of the language will allow affected users the opportunity to become familiar with the stipulations as management strategies are developed for the upcoming season.

The revised agreement addresses a number of salmon fisheries in southeast Alaska, including those near the Alaska/British Columbia border and on several transboundary rivers.

ALASKA: Work continues on federal plan for Cook Inlet salmon

December 28, 2018 — More than two years after a court ruling ordered the North Pacific Fishery Management Council to develop a management plan for the Cook Inlet salmon fishery, a stakeholder group has made a first set of recommendations.

The council convened a Cook Inlet Salmon Committee last year composed of five stakeholders to meet and offer recommendations before the council officially amends the Fishery Management Plan, or FMP, for the drift gillnet salmon fishery in Upper Cook Inlet, which occurs partially in federal waters.

The committee presented a report with three main findings: first, that the fishery be managed cooperatively with the State of Alaska; second, that the committee schedule another meeting before the April 2019 council meeting; and third, that fishery participants be prohibited from retaining groundfish.

The council went into rewriting the FMP for Cook Inlet unwillingly. The whole battle began in 2012 when the council voted unanimously to pass Amendment 12 to the existing Cook Inlet FMP, which essentially delegated all management authority for the fishery to the Alaska Department of Fish and Game, along with the management of two other salmon fisheries in Prince William Sound and the Alaska Peninsula.

The Cook Inlet Fishermen’s Fund and the United Cook Inlet Drift Association, the trade group for the drift gillnet fleet in the area, sued the National Marine Fisheries Service to restore the FMP to the fishery. After losing in the U.S. District Court of Alaska, the groups prevailed at the 9th Circuit Court of Appeals in fall 2016.

Study: Northwest Salmon Not Immune To Ocean Acidification

December 27, 2018 — A new study suggests that salmon will not be immune to the effects of ocean acidification. Scientists found that changes to ocean chemistry disrupt a fish’s ability to smell danger in the water.

Researcher Chase Williams of the University of Washington exposed young coho salmon to the elevated ocean CO2 levels expected over the next few decades. He then dropped in an odor that normally makes the fish react as if a predator is near. The fish ignored it.

“They’re still smelling odorant, but the way their brain is processing that signal is altered … Before, they would avoid this predator odor and now they’re more indifferent to it,” Williams said.

The results are concerning because salmon rely on smell to avoid danger, find food and to find their way back to spawning grounds in West Coast rivers.

Co-author Andrew Dittman is a scientist with the federal Northwest Fishery Science Center. He said the results could apply to other salmon species.

“The mechanisms involved … are very similar. So the expectation would be that we would see relatively similar phenomena in the other species as well,” he said.

Salmon to lose sense of smell as CO2 levels rise

December 19, 2018 — As atmospheric CO2 levels continue to rise, increasing amounts of carbon dioxide will be absorbed into the ocean. New research suggests rising CO2 levels in the ocean could disrupt the olfactory abilities of coho salmon.

Salmon rely on their sense of smell to track prey, find mates and navigate their way back upstream to spawn. According to the new study, published this week in the journal Global Change Biology, a compromised sense of smell would pose a serious threat to the health of salmon populations.

Lab experiments showed rising acidity levels caused by elevated CO2 levels inhibits salmon’s already vulnerable sensory-neural system.

“Our studies and research from other groups have shown that exposure to pollutants can also interfere with sense of smell for salmon,” Evan Gallagher, a professor of toxicology at the University of Washington, said in a news release. “Now, salmon are potentially facing a one-two punch from exposure to pollutants and the added burden of rising CO2. These have implications for the long-term survival of our salmon.”

WASHINGTON: 6.2 million salmon fry in incubators die during power outages

December 19, 2018 — Millions of salmon fry were killed during last week’s power outages.

The fry were in incubators at the Minter Creek Hatchery in Gig Harbor. The pump that supplies water to the incubators lost power, and the backup generator failed. As many as 6.2 million chinook salmon fry died, according to a news release from the Washington State Department of Fish and Wildlife (WDFW).

“This is a devastating loss,” Eric Kinne, WDFW hatchery division manager, said in the release. “The department is conducting an analysis to determine the root cause of what went wrong so that we can improve procedures at Minter Creek and our other hatcheries to help ensure this doesn’t happen again.”

JACK PAYNE: Endangered species science is itself endangered

December 19, 2018 — Catching chinook salmon today requires gear, technique, experience and luck. Catching salmon a year or a decade from now requires science.

That means local science. The recent National Climate Assessment notes that Alaska’s temperature has been warming at twice the global rate. To get at what this means for Alaskans, we need University of Alaska scientists.

Alaskans are getting a better handle on what a warming world does to salmon runs through the work of a federally funded corps of local fisheries researchers based at the University of Alaska Fairbanks. Known as the Alaska Cooperative Fish and Wildlife Research Unit, its researchers address climate questions from an Alaska perspective.

For example, they research how melting glaciers can increase or diminish salmon numbers and for how many years. They consider how the increasing frequency of wildfires plays out on salmon streams. They compare how the same conditions can have different effects on sockeye, coho and chinook salmon.

It’s not the gloom and doom of a planet in peril. In some ways, climate change appears to have boosted some salmon counts, at least temporarily.

An accurate salmon count depends in part on a good scientist count. Here, the news is not good. Until I hired Alaska assistant unit leader Abby Powell to come run the University of Florida Cooperative Fish and Wildlife Research Unit three years ago, the Alaska unit had five faculty members. It’s down to two.

Slowly starving for lack of federal funding, Alaska’s fish and wildlife species science is itself becoming an endangered species.

The national Cooperative Fish and Wildlife Research Unit (CRU) program was established in 1935 on the premise that science, not politics, should guide management of national treasures such as eagles, bison, and moose. An administration proposal to de-fund it does away with that premise.

Report finds seafood mislabeling “rampant” in New York

December 18, 2018 — The New York Attorney General’s office may take enforcement action against some supermarket chains after it found “rampant” seafood mislabeling at grocers across the state, according to a recent report.

The report, from New York Attorney General Barbara D. Underwood, found that around a quarter of the seafood sampled at New York grocery retailers was mislabeled. These findings are the result of the first major U.S. government investigation of seafood fraud at supermarket chains.

The incidence of mislabeling popular species was “rampant” among New York retailers, the Underwood’s office said in statement. For example, 27.6 percent of species sold as “wild” salmon were mislabeled, oftentimes being substituted for farmed salmon.

A significant 67 percent of red snapper samples were mislabeled, the report found. Approximately 87.5 percent of lemon sole was also discovered to be mislabeled.

“The substitutes were often cheaper, less desirable, and less environmentally sustainable species,” the AG office statement said. “This includes farm-raised salmon sold as wild salmon, lane snapper sold as red snapper, and swai sold as lemon sole.”

Ray Hilborn, a professor of marine science at the University of Washington and a member of the International Fisheries Innovation Network steering committee, said the report showed the mislabeling was at times intentional and at times accidental.
