Cardiorespiratory fitness of farmed Atlantic salmon unaffected by virus

March 14, 2019 –The respiratory systems of Atlantic salmon function normally even when carrying large loads of piscine orthoreovirus (PRV), new UBC research has found.

“We didn’t find significant harm to the fish’s respiratory physiology despite the virus replicating to a load equal to, if not higher, than those seen naturally in wild or farmed fish” said Yangfan Zhang, a Ph.D. student in UBC’s faculty of land and food systems and lead author of the study published today in Frontiers in Physiology.

PRV is present in nearly all farmed Atlantic salmon on Canada’s west coast, and various strains of PRV have been detected in many salmonid species around the world. Consequently, the results are a positive step in reducing the uncertainty about the potential of infected farmed Atlantic salmon in marine pens to negatively impact migrating wild Pacific salmon.

New Pacific Salmon Treaty cuts chinook catch

January 9, 2019 — The new Pacific Salmon Treaty went into effect on the first of the year after the treaty’s last 10-year iteration expired on its own terms on 31 December.

The Pacific Salmon Treaty is renegotiated every decade between the United States and Canada to govern salmon catch, research, and enhancement in Alaska, Oregon, Washington, and British Columbia.

The Alaska Department of Fish and Game made public last week the sections of the treaty that will directly affect Alaskan salmon fisheries, which deal with Transboundary Rivers, Northern British Columbia and Southeastern Alaska, and Chinook salmon.

In an attempt to battle a dramatic multi-year drop in Chinook stocks off of the Pacific coast, the countries agreed to cut their catch of Chinook salmon, with a reduction of up to 12.5 percent in Canada and up to 7.5 percent in the United States.

Some in the industry are not pleased with the new treaty.

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.

Feds: US fishermen had good year aided by lobsters, scallops

December 14, 2018 — PORTLAND, Maine — U.S. commercial fishing generated more than $144 billion in sales in 2016, buoyed by growth in key species such as sea scallops and American lobsters, the federal government reported on Thursday.

The National Oceanic and Atmospheric Administration said the total of $144.3 billion in sales from commercial fishing in 2016 was up about $100 million from the previous year. The agency released the figure as part of its annual Fisheries Economics of the United States report, one of two reports about the health of fisheries that came out on Thursday.

The economics report states that the industry was boosted by growth in value of some economically critical species, also including shrimp, but other big-money species such as Alaska pollock and pacific salmon were down from the previous year.

The report shows U.S. fisheries holding steady, and continuing to play a critical role in the economies of states from Maine to California, said Ned Cyr, director of NOAA Fisheries Office of Science and Technology.

Washington: Lawmakers consider bill to ban commercial net pens for fish farms after massive spill

January 11, 2018 — OLYMPIA, Wash. — A bill that would ban commercial net pens used for fish farms in Washington State is now being considered in Olympia.

It comes after last August’s massive spill in the Puget Sound where tens of thousands of Atlantic salmon were released near the San Juan Islands, and more than 105,000 remain unaccounted for.

“That is a great concern,” said Sen. Kevin Ranker, (D-Orcas Island), who is sponsoring the bill that would ban Atlantic salmon farms in Washington.

On Tuesday, Ranker testified at a hearing of the Senate Agriculture, Water, Natural Resources & Parks Committee.

“Having these fish, which are considered – under our own laws – a pollutant in our ecosystem makes no sense if we are going to continue to recover our marine ecosystem,” said Ranker.

Ranker is worried about more fish escaping from net pens in the future and the daily operations of the facilities owned by Canadian-based Cooke Aquaculture.

“Frankly, this bill kills rural jobs,” said Troy Nichols of Phillips Burgess Government Relations who testified on behalf of Cooke Aquaculture.

Cooke Aquaculture employs 80 people at its eight facilities in Washington.

“We do an excellent job raising fish there- here in the Puget Sound, said Tom Glaspie who is the farm manager at Cooke’s Hope Island facility. “We give it our all. We care about the environment. Most of us are fishermen; (our) families have fished, and we’re proud to be Washingtonians.”

Sens. Cantwell, Murray, WA Democratic Reps. Urge Immediate Action from Feds to Protect Native Salmon from Fish Farm Fiasco

Members: Agencies must also immediately halt permitting of new and expanding net pens

August 31, 2017 — WASHINGTON — The following was released by the office of Senator Maria Cantwell:

Today, U.S. Senators Maria Cantwell (D-WA) and Patty Murray (D-WA), joined by Reps. Adam Smith (WA-09), Pramila Jayapal (WA-07), Rick Larsen (WA-02), Derek Kilmer (WA-06), Denny Heck (WA-10), and Suzan DelBene (WA-01), wrote an urgent letter to the heads of the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Army Corps of Engineers to press the two agencies to take quick and decisive action to address the impacts of hundreds of thousands of escaped farmed Atlantic salmon in Washington state waters.

Citing the importance of wild salmon fisheries to Tribes, fishermen, and ecosystems in the state, the members of Congress are calling on NOAA and the Army Corps to direct federal resources to mitigate the risks of this incident, including the capture of the escaped farmed salmon. The letter also calls on the Army Corps to work to stop all permitting for new net pens or expansions to existing pens, as well as prioritize requests to update or maintain existing pens.

“Pacific salmon are central to our economy, our culture, and our environment in the Pacific Northwest, and are a critical part of marine and estuarine ecosystems in Washington state,” the members wrote. “The released Atlantic salmon pose a threat to wild Pacific salmon, including multiple endangered and threatened stocks in the region. Tribes, fishermen, and state agencies are working to respond to the escapement but the scale of the release calls for immediate and direct federal response…”

The farmed salmon escaped from a damaged facility owned by Cooke Aquaculture on August 19th and 20th. Since the breach, farmed Atlantic salmon have been found as far afield as Canadian waters on the West side of Vancouver Island, as well as the Skagit and Nooksack Rivers. The released Atlantic salmon pose a threat to wild Pacific salmon, including multiple endangered and threatened stocks in the region. Farmed salmon tend to be larger and could outcompete wild salmon for critical resources such as prey and preferred habitat, which is important for spawning.

Tribes and federal and state agencies have worked tirelessly towards restoration of wild salmon populations in Puget Sound. At a time when stocks of many types of wild Pacific salmon are at historic lows, the escape of thousands of farmed salmon could be a devastating setback.

The members also asked the agency heads to conduct a review of the integrity and operation of all currently operating net pen structures to address concerns of further accidents at existing facilities.

Text of the letter can be found below.

Dear Acting Administrator Friedman and Mr. Lamont,

We write to request the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Army Corps of Engineers (Army Corps) immediately act to minimize the impact of the Atlantic salmon net pen failure near Cypress Island in Skagit County, Washington. The released Atlantic salmon pose a threat to wild Pacific salmon, including multiple endangered and threatened stocks in the region. Tribes, along with federal and state agencies have worked tirelessly to restore wild salmon in Puget Sound and the escapement of thousands of farmed salmon could be a devastating setback.

Pacific salmon are central to our economy, our culture, and our environment in the Pacific Northwest, and are a critical part of marine and estuarine ecosystems in Washington state. Pacific salmon support treaty rights for Tribes throughout the region, commercial and recreational fishers, as well as predators like the endangered Southern resident orcas. On August 19th, potentially hundreds of thousands of farmed Atlantic salmon were released into the Puget Sound ecosystem due to the structural failure of a net pen. While the fish farm facility was permitted under Washington state law, the escapement may negatively impact resources under the jurisdiction of NOAA, the Army Corps, and other federal agencies. Most concerning is the threat farmed Atlantic salmon pose to the wild Pacific salmon populations stocks in Puget Sound. Farmed salmon tend to be larger and could outcompete wild salmon for critical resources such as prey and preferred habitat, which is important for spawning.

Tribes, fishermen, and state agencies are working to respond to the escapement but the scale of the release calls for immediate and direct federal response including mitigation, scientific support, and funding to improve response and capture of the released Atlantic salmon. Further, as other net pens remain in our waters, we request the Army Corps halt all permitting for new net pens or expansions to existing net pens, while prioritizing permit requests to upgrade and maintain existing net pens. In addition, we ask NOAA and the Army Corps to review the integrity and operation of all existing net pen structures to determine any additional threats to wild salmon in the area and prevent any further escapement of farmed salmon into our waters.

We appreciate your ongoing work to restore Pacific salmon in Puget Sound and throughout the Pacific Northwest.

Sincerely,
