Salmon virus has spread from the Atlantic to the Pacific

May 27, 2021 — Wild Chinook salmon are more likely to be infected with Piscine orthoreovirus (PRV) the closer they are to salmon farms. This finding indicates that farms are spreading the virus to wild salmon – a theory that is further supported by the results of a recent genomic analysis.

Dr. Gideon Mordecai is a viral ecologist at the University of British Columbia who led the study.

“Both our genomic and epidemiological methods independently came to the same conclusion, that salmon farms act as a source and amplifier of PRV transmission,” said Dr. Mordecai. “Because separate lines of independent evidence all point to the same answer, we’re confident in our finding.”

In collaboration with researchers from the Strategic Salmon Health Initiative, the UBC team traced the origins of PRV to Atlantic salmon farms in Norway and found that the virus is now widespread across salmon farms in British Columbia.

After sequencing 86 PRV genomes, the researchers estimated that the lineage of the virus that is now present in the Northeast Pacific diverged from the virus in the Atlantic Ocean approximately 30 years ago. This suggests that the introduction of PRV to British Columbia, and the infection of wild Pacific salmon, is a relatively recent phenomenon.

Community Steps Up to Continue Yukon River Salmon Research During Pandemic

May 20, 2021 — The following was released by NOAA Fisheries:

On the Yukon River, Chinook salmon are woven into the fabric of life and culture. They are a resource that indigenous people have harvested for more than 1,000 years. But over the last 20 years or more, the Chinook populations have declined dramatically. Fewer Chinook are returning to the river each year, and those that do are smaller and younger than they have been in the past. This has created hardship for the people who rely on this resource. It is nurturing a strong desire to understand and contribute to solutions to address the dwindling returns.

Ragnar Alstrom, Executive Director of Yukon Delta Fisheries Development Association, explains it this way: “We want to be a part of figuring out why our Chinook aren’t returning. Instead of standing by and waiting for someone else to figure it out, we want to be engaged in the science.”

So began a special partnership between NOAA Fisheries, Alaska Department of Fish and Game, and local fishermen from the villages of Emmonak and Alakanuk. Starting in 2014, the Yukon Delta Fisheries Development Association (YDFDA) worked with scientists to identify nine permanent sampling stations on the three main lower Yukon distributaries. Each summer, local fishermen and NOAA Fisheries biologists work together. They set and retrieve salmon sampling nets, identify and count the catch, and measure water temperature and depth. They send salmon samples to the NOAA Fisheries Auke Bay Laboratories where their diet and body condition are analyzed.

North Pacific Council’s New Public Comment Policy Triggers Intense Reactions

May 6, 2021 — Personal attacks and profanity laced five of the 250 written comments submitted to the North Pacific Fishery Management Council last month on just one of the half dozen issues before the Alaska fisheries management panel. Council staff pulled the comments after they’d been live for a few hours and reached out to each author to ask them to resubmit their comments without the offensive language. Only one did.

The issue was abundance based management (ABM) of halibut in the Bering Sea, where far more halibut is taken as incidental bycatch in bottom trawls than by halibut quota holders with their longline gear, and salmon bycatch in mid-water trawls in an area that has seen precipitous drops in Chinook returns. Public testimony during the meeting was intense but for the most part civil. ABM and bycatch is one of a few lightning-rod issues — like the on-shore/off-shore fight over the Bering Sea/Aleutian Island fisheries and others — that the council has faced in the nearly half century it has managed Alaska’s federal fisheries.

ALASKA: Commercial and subsistence harvesters speak out against trawler bycatch of Chinook salmon

April 22, 2021 — Alaska’s commercial fishermen have been speaking out against big trawlers for years, complaining that the large vessels in federal waters are scooping up mature and juvenile fish. The regional council that manages federal fisheries recently heard from hundreds concerned about the number of salmon and other species that end up as bycatch in trawl nets.

For Alaska’s troll fleet, king salmon is their money fish. In state waters, small crews on these 40 to 50-foot boats — or even small skiffs — will catch a fish at a time, and it’s worth it: Chinook salmon can fetch $6 a pound from a processor.

But there’s another big-money fish in Alaska: Pollock. It’s the white fish found in a McDonald’s Filet-O-Fish® or an imitation crab stick. And the factory trawlers that ply the Bering Sea and Gulf of Alaska in search of pollock and other groundfish scoop up Chinook salmon and other species in their wide nets.

Federal fisheries data show trawlers in the North Pacific took about a tenth of the Chinook — or king salmon — caught by Alaska’s commercial salmon fleet last year. And those numbers are tracking the same this year. But none of that catch happens on purpose.

Preliminary ADF&G data show about 263,000 kings were commercially harvested last year statewide. As of last week (April 15), bycatch in the Bering Sea and Gulf of Alaska areas for 2021 was around 16,000 fish, over six percent of last year’s statewide commercial harvest. Last year’s trawler bycatch was 26,000 kings, or about a tenth of the 2020 commercial Chinook harvest in-state.

PFMC sets 2021 West Coast ocean salmon season dates

April 16, 2021 — The following was released by the Pacific Fishery Management Council:

The Pacific Fishery Management Council has adopted ocean salmon season recommendations for 2021. The seasons provide recreational and commercial opportunities for most of the Pacific coast and achieve conservation goals for the numerous salmon stocks on the West Coast.

The recommendations will be forwarded to the National Marine Fisheries Service (NMFS) for approval by May 16, 2021.

“There will be some restrictive commercial and recreational seasons this year along much of the coast,” said Council Chair Marc Gorelnik. “Forecasts for some Chinook and coho stocks are quite low, which made our job more challenging this year.”

The Council heard reports from commercial, recreational, and tribal representatives on the challenges caused by the COVID-19 pandemic, as well as ways the Council could provide meaningful fishing opportunities and economic support for coastal communities.

Feds enforcing fishery, distancing rules to protect southern resident orcas

April 15, 2021 — For a third year in a row, the federal government has ordered fishery closures and imposed limits on vessel movements to protect the critically endangered southern resident killer whale population.

The measures by the Department of Fisheries and Oceans focus on the main threats to the orcas: lack of access to Chinook salmon stocks, acoustic and physical disturbance, and contaminants.

The commercial and recreational salmon fishery will be closed in a portion of Swiftsure Bank from July 16 to Oct. 31, and in Juan de Fuca Strait from Aug. 1 to Oct. 31.

DFO is also enforcing a new closure for commercial and recreational salmon fisheries in the southern Gulf Islands, where closures will be triggered by the first confirmed presence of southern resident killer whales in the area.

Monitoring will begin in the area on June 1. If a southern resident killer whale sighting is confirmed, the fishery will be shut down and remain closed until Oct. 31, the department said.

Distancing measures will also be enforced. For a second year, vessels will be prohibited from coming within 400 metres of any orca in coastal waters between Campbell River and Ucluelet, including Barkley and Howe Sound. This is in effect year-round until May 31, 2022.

ALASKA: Big sockeye runs and struggling kings leave Bristol Bay managers with a complicated balancing act

April 2, 2021 — Fifty-one million sockeye are forecast to return to Bristol Bay this summer.

If that holds, commercial fishermen will be able to harvest around 37 million reds. That’s 13% more than the average harvest of the past decade.

But concerns remain about the numbers of chinook salmon in the Nushagak District on the west side of Bristol Bay — which leaves the biologists who manage the fishery with a complicated balancing act.

Faced with another huge sockeye run this summer, managers in the Nushagak District say they will try to allow fishermen to harvest the sockeye and also conserve chinook.

Tim Sands, the district’s area management biologist, describes the job as trying to walk a fine line between “getting as many kings up the river as we can, but still provide opportunity to harvest sockeye salmon.”

For years, biologists around the state have wrestled with declining numbers of chinook, fish that are central to subsistence ways of life across Alaska, and also targeted by sport fishermen. Since 2007, the state’s chinook runs have consistently declined, forcing managers to restrict or close fishing in certain areas.

Feds May Look at Spring-Run Chinook Salmon as Genetically Distinct

March 16, 2021 — The National Marine Fisheries Service is considering whether the spring-run and fall-run Chinook salmon that occupy the rivers of Northern California and southern Oregon are genetically distinct.

The decision has huge implications for fish populations as the number of spring-run Chinook salmon has plunged to such depths it would almost certainly result in a listing under the Endangered Species Act if seen as a separate species.

“The science is in on that,” said Rich Nawa, an ecologist who petitioned the agency a year ago to consider the spring-run Chinook salmon as genetically distinct. “There are several papers so no one disputes the science, it’s just how to incorporate it into policy at this point.”

The fisheries service said Monday it will consider the new science as it analyses whether an update to its listing policy is warranted.

“We find that the petition presents substantial scientific and commercial information indicating the petitioned action may be warranted,” the agency said in a document.

The key word in the phrase is “may,” as a significant dispute exists in the scientific community whether the spring-run Chinook is what is referred to as an “evolutionarily significant unit.”

Pacific Fishery Management Council releases alternatives for 2021 West Coast ocean salmon fisheries

March 11, 2021 — The following was released by the Pacific Fishery Management Council:

The Pacific Fishery Management Council has adopted three alternatives for 2021 ocean salmon fisheries off Washington, Oregon, and California for public review. The Council will make a final decision on salmon seasons at its meeting on April 6-9 and 12-15. Detailed information about season starting dates, areas open, and catch limits for the three alternatives are available on the Council’s website at www.pcouncil.org.

Forecasts for many Chinook and coho stocks have improved over last year; however, the Council is constrained by requirements to conserve Fraser River (Canada) Washington coastal and Puget Sound natural coho runs, lower Columbia River natural tule[1] fall Chinook, and Klamath River fall Chinook.

“Meeting our conservation and management objectives continues to be the highest priority for the Council,” said Council Executive Director Chuck Tracy. “Balancing those objectives while providing meaningful commercial and recreational seasons remains a challenge in 2021.”

Council Chair Marc Gorelnik said, “the Council is considering the needs of Southern Resident killer whales as part of its deliberations. We are also considering the need to rebuild some Chinook and coho stocks that have been designated as overfished.”

WASHINGTON: Forecast for Puget Sound Spring Chinook Up from Last Year, but Still Low

March 10, 2021 — Forecasts for this year’s salmon runs show a doubling of spring chinook in the Nooksack River, giving room for hope even though the species remains threatened across the Puget Sound region, according to fisheries managers and environmental officials.

Projected runs for 2021 show 7,540 spring chinook returning to the north fork of the Nooksack River, almost double the 3,949 fish that returned in 2020, according to Fish and Wildlife data published in late February.
