Alaska cod: Gulf cod stocks creep back, but Bering and Aleutian still down

April 5, 2021 — Pacific cod stocks have begun to rebound in the Gulf of Alaska, but the TAC for 2021 remains low at 17,321 metric tons. Last year managers curtailed the fishery in federally managed waters after stock assessments put the biomass near the bottom of the threshold for conducting the fishery.

Though the recruitment of younger cod and the uncaught fish from last year have added to the abundance in most recent assessments, full recovery of the stock could take years. The warm-water blob of 2014 has been blamed for the crash.

The warming waters began in 2013 and precipitated a 79 percent decline in the stocks. Prevalent theories suggest that warmer waters raise the metabolic rates for the young cod. At the same time the forage species for young cod appeared to have higher concentrations of protein and lower concentrations of fat. More recent studies determined that the eggs of cod survive in a narrow range of temperature (3 to 6 degrees C, or 37.4 to 42.8 degrees F).

Stocks also continue to decline in the Bering Sea and Aleutian Islands harvest areas. The 2021 TAC for the Bering Sea has been set at 111,380 metric tons with a TAC of 13,796 metric tons for the Aleutian Islands.

The 2020 TACs for the respective areas had been set at 141,799 metric tons and 14,214 metric tons.

By plane, boat and man basket, COVID-19 vaccines flow to Alaska’s Aleutian seafood workers

March 30, 2021 — Thousands of Alaska seafood workers are getting vaccinated for COVID-19 three months after outbreaks swept through Aleutian plants, shuttering some just as the lucrative Bering Sea fishing season began.

The effort is taking different forms, ranging from clinics in Sand Point to a one-day mass event in the Unalaska gym and aboard Dutch Harbor boats that vaccinated about 1,500 plant workers and deep-sea fishermen.

Probably the most only-in-Alaska method involved Eastern Aleutian Tribes community health aide Joe McMillan, who on Thursday clambered into a small man basket suspended in the air to swing aboard two large processing vessels and vaccinate more than a hundred people on each.

The doses now going into seafood worker arms are coming from a federal allocation provided to Eastern Aleutian Tribes rather than from state supplies of vaccine.

They came via a Biden administration plan to expand vaccine availability to community health centers in underserved communities. The Eastern Aleutian Tribes is one of just two tribal entities in Alaska participating in that program as of March 22.

The tribal health organization has probably given out 2,500 shots in the past week and 4,000 since January, according to CEO Paul Mueller, who described one chartered flight Wednesday to deliver food and vaccine that skipped from Nelson Lagoon to Cold Bay, False Pass, Sand Point, Dutch Harbor and King Cove.

In the Aleutians, climate change and ocean acidification impacts add to legacies of past exploitation

March 2, 2021 — In the waters around the Aleutian Islands, the 1,200-mile chain that arcs across the southern edge of the Bering Sea from Alaska to Kamchatka, modern climate change has layered atop a centuries-old legacy of human assaults to send combined impacts cascading through the marine ecosystem.

Evidence is in the once-colorful corals that have nurtured schools of fish supporting some of the world’s largest commercial seafood harvests. Under the clear waters is a pale world that signals a habitat in a tailspin.

The pale-pink scene shows the slow death of cold-water coral reefs that used to be buffered by the kelp, said Doug Rasher, a marine ecologist with the Maine-based Bigelow Laboratory for Ocean Science. “We’re passing the tipping point where these reefs have persisted and been able to survive,” said Rasher, who led a study of the coral ecosystem’s downward spiral.

The reefs are dying because they are being attacked by an exploding population of sea urchins. Having mowed down the surrounding kelp forest, the urchins are consuming the algae that the reefs produce to build their structures. The urchin population is booming because the sea otters that used to eat them have disappeared.

Climate change also weakens the corals. Warmer waters make the urchins grow faster, requiring them to eat more. Rasher’s study examined the algae’s microscopic growth layers and found that urchin foraging increased by up to 60 percent since preindustrial times.

Adding to the assault is ocean acidification, to which the Bering Sea is especially vulnerable. The shallow Bering, with its relatively cold waters, abundant sea life and wide seasonal fluctuations, is naturally primed to hold carbon. And carbon emitted by fossil-fuel burning is absorbed from the atmosphere into the water, lowering pH levels and threatening calcium-building life forms — not just the coral reefs, but shellfish such as crabs, as well the tiny creatures such as pteropods that make up the diet of fish like salmon.

Unscathed: These Alaska villages are reaching herd immunity — without a single case of COVID-19

February 26, 2021 — For years, residents of the Southeast Alaska fishing town of Pelican decried cuts to state ferry service that left them increasingly isolated.

Then came news of a deadly pandemic spread around the world by travelers.

“Everybody claims that it’s so hard to get in and out of here. I say, that’s perfect,” said Walt Weller, Pelican’s mayor. “There is no better time to be stranded in the middle of nowhere.”

A year into the pandemic, Pelican — reachable only by bush plane or boat — has zero recorded cases of COVID-19 and has vaccinated more than half its adults.

State officials say privacy considerations bar them from identifying communities without cases. But interviews and social media posts indicate Pelican is not alone. Alaska’s unique geography and isolation have helped some of its villages thwart the pandemic with astonishing success.

The state’s list of COVID-free communities includes at least 10 places, stretching from Pelican to the Aleutian Islands to deep in the Interior. In Southwest Alaska, where many communities have seen major outbreaks, officials at the regional tribal health care provider say six villages have nonetheless recorded no coronavirus cases at all.

Partners Provide Critical Support in Unprecedented Year for Alaska Research and Fisheries Management

January 29, 2021 — The following was released by NOAA Fisheries:

Each year, NOAA Fisheries scientists compile information from a variety of sources to produce and update annual indicators of ecosystem status in the Bering Sea, Gulf of Alaska and Aleutian Islands. Data and information are provided by federal, state, academic, non-government organizations, private companies, and local community partners across Alaska. Collected data complement NOAA Fisheries’ own research.

However, in 2020 several key NOAA research surveys were cancelled. Collaboration, increased engagement by community and research partners, and creative thinking on the part of some NOAA scientists helped fill critical information gaps. As a result, the annual Ecosystem Status Reports still could be produced.

“Around 143 individuals contributed to the three Ecosystem Status Reports we produced this year,” said Elizabeth Sidden, editor of the Eastern Bering Sea Ecosystem Status Report and a scientist at the Alaska Fisheries Science Center. “The success of this continuing effort to provide valuable ecosystem context to better understand factors contributing to fish stock fluctuations hinges on these partnerships. We couldn’t do this without the help of fellow researchers and local communities along with our staff contributions.”

One example of the kind of information provided by partners this year in all regions is seabird data. The U.S. Fish and Wildlife Service (U.S. FWS) was unable to conduct field research due to COVID-19 travel restrictions. Coastal community members, tribal governments, and state and university partners provided information on seabird dynamics for the Bering Sea region. U.S. FWS biologists then synthesized that data. In the Gulf of Alaska, they provided opportunistic observations that were incorporated into the Ecosystem Status Report along with other information from non-profits, The Coastal Observation and Seabird Survey Team (COASST) and U.S. Geological Survey.  Seabird biology and ecology are bellwethers of environmental change, which is one of the reasons they are important ecosystem indicators.

NOAA scientists also identified other sources of information to develop ecosystem indicators in 2020.  For instance, they used satellite data to measure sea surface temperatures in the Bering Sea since they weren’t able to collect these data during annual research surveys. They also were able to process and analyze data collected from previous years of surveys.

COVID-19 Outbreak At Aleutian Processing Plant Grows To 135

January 28, 2021 — A COVID-19 outbreak at one of Alaska’s largest fish processing plants has infected nearly 20 percent of workers, with testing only partially finished, officials said Tuesday.

At Trident Seafoods’ huge plant on the remote Aleutian island of Akutan, 135 of 700 workers have tested positive for the virus, state officials reported Tuesday.

The company has only tested about half of its workforce, and Dr. Joe McLaughlin, the state epidemiologist, said at a news conference that the outbreak is still on an “upward trajectory.”

“I don’t think this outbreak is going to end in the next several days,” McLaughlin said. “I think it’s going to go on for a while.”

Trident officials announced a three-week closure last week after a handful of workers tested positive for COVID-19, just as the billion-dollar pollock fishing season kicked off.

Size of Alaska’s Western Aleutian Island Passes Larger than Previously Thought

December 15, 2020 — The following was released by NOAA Fisheries:

There are thousands of small islands that comprise Alaska’s Aleutian Island chain, but only a few dozen significant passes among those islands. These passes are important bottlenecks for water exchange among the North Pacific, Gulf of Alaska, and the Bering Sea. However, until now there has been limited detail on estimates of pass location, size, shape, length, and depth.

“Flow estimates have been based on rough pass size estimates from over 50 years ago,” said Mark Zimmermann, fisheries biologist from the Alaska Fisheries Science Center. “We have updated information for eastern, western and central passes along the Aleutian Island chain. This new information will help oceanographers and ecologists better quantify impacts of water flow on Alaska marine ecosystems and better understand environmental and ecological changes that are taking place.”

Two new NOAA Fisheries’ studies provide more detail on the size and extent of the passes and the shoreline around the Aleutian Islands.

One study showed that all of the western-most Aleutian passes, from Kavalga to Semichi, are larger (18 to 71 percent) than previously reported. The last study was conducted for this area in the 1960s. This includes Amchitka Pass (+23 percent), the largest in the Aleutians.

The other study focused on the easternmost pass, False Pass, which posed a particular challenge for co-author Zimmermann. False Pass is unusual: it’s the only Aleutian pass that directly connects the shallow shelves of the western Gulf of Alaska and eastern Bering Sea. It is also the only pass with constricted southern and northern openings. We found this pass to have a single northern inlet to the Bering Sea—however, until recently it had two. This conflicts with current navigational charts, depicting two inlets to the Bering Sea now, compared to just one on the older charts (1926–1943).

“Our analysis of eastern pass sizes compared to the results of the 1960s study generated mixed results,” said Zimmermann. “In some cases, our pass size estimates were larger while in other cases they were smaller than previous estimates.”

In 2005, NOAA scientists updated information on some of the eastern and central passes. When Zimmermann looked at the two eastern passes from that study, he found that they were actually larger than previously thought. He also found that five central Aleutian passes were smaller than reported. The earlier study did not examine western pass sizes. The new studies include much more detailed information about the seafloor and shoreline that was not available at the time of the earlier analyses. As a result, they will be a great new resource for oceanographers and ecologists studying marine systems.

NOAA cancels Alaskan research surveys citing COVID-19

May 26, 2020 — The National Oceanic and Atmospheric Administration (NOAA) has canceled five of the six large-scale research surveys scheduled to take place in the waters off Alaska this year due to the COVID-19 pandemic, according to an NOAA press release.

The release cited the unique challenges and uncertainties posed by the coronavirus crisis, which have resulted in the cancellation of the Aleutian Islands bottom-trawl survey, the eastern Bering Sea bottom-trawl survey, the northern Bering Sea bottom-trawl survey, the Bering Sea pollock acoustics survey, and the fall ecosystem survey. The Alaska longline survey will go ahead as planned.

The Salmon Sisters of Alaska are Fighting for a Healthy, Sustainable Fish Future

January 15, 2020 — The remote Aleutian Islands are a group of 14 large volcanic islands and 55 smaller islands, mostly belonging to the state of Alaska, known for challenging weather and strong winds. But that has never stopped sisters Claire Neaton (pictured at right, above) and Emma Privat (at left), 29 and 28 respectively, from fishing for halibut and salmon in the archipelago’s waters.

Neaton and Privat are commercial fishermen who grew up on an off-the-grid homestead in this remote region. In 2012, the pair founded Salmon Sisters, a seafood and apparel company that is gaining national recognition and helping feed hungry Alaskans via the Give Fish Project. (Like many female fish harvesters, they choose the term fishermen to describe themselves.)

The sisters fish for salmon, cod, and halibut alongside their family members, including their father who still fishes during the summer months. Currently, the family has four boats with crews of up to five people.

Alaska produces more wild seafood than all the other states combined—and its strict conservation practices and pristine marine waters set it apart on the global market, according to a 2017 report by the Alaska Seafood Marketing Institute. The state has written sustainable fishing practices into its constitution, and many entities—fishermen, scientists, conservationists, and government organizations—collaborate to make sure fish are caught by methods that maintain fish stocks and minimize harm to the plants and animals in the marine environment.

Scientists, Fishermen Team Up to Track Cod in Alaska’s Outermost Aleutian Islands

January 9, 2020 — SEAFOOD NEWS — Last winter scientists and Alaskan fishermen agreed to launch a pilot study to develop methods for tagging cod on active commercial fishing vessels in the Aleutian Island.

Satellite tags had never been used on Pacific cod. No one had recorded seasonal movements of cod in the Aleutian Islands. This was the first time industry, scientists, and the fishing community all took part in the research.
