Warming conditions are making northern Bering Sea more friendly for pink salmon

September 22, 2020 — Pink salmon, the most plentiful and cheapest of Alaska’s five salmon species, are finding more hospitable habitat in the warming northern Bering Sea, a new study finds.

There is a clear link between warming temperatures at Nome and better juvenile salmon productivity in rivers that flow into the northern Bering Sea, said the study, published in the journal Deep Sea Research Part II: Topical Studies in Oceanography.

Pink salmon, a species more associated with waters off Alaska’s southern coast, appear to be among those boreal species working their way into more northern waters in response to climate change.

Pink salmon’s short life cycle makes their population more adaptable to these changes in environmental conditions, according to the study. Other salmon species spend up to seven years at sea before returning to freshwater to spawn, but pink salmon have a total life cycle of only two years — counting their time in both saltwater and freshwater — and that relatively quick turnaround gives more chances for succeeding generations to shift their migration patterns.

“Pink salmon are definitely good at straying,” said lead author Ed Farley of the National Oceanic and Atmospheric Administration. “They definitely want to go seek out other habitat.”

ALASKA: Pandemic restrictions create uncertainties for Bering Sea crab fleet

September 16, 2020 — Bering Sea crabbers will soon know how much they can pull up in their pots for the season that opens Oct. 15.

This week the Crab Plan Team, advisers to state and federal fishery managers who jointly manage the fisheries, will review stock assessments and other science used to set the catches for Bristol Bay red king crab, Tanners and snow crab.

Normally, the biggest driver would be data from the annual summer trawl surveys that have tracked the stocks for decades. But this year, the surveys were called off due to the coronavirus, and that has crabbers worried.

“There are certainly some added uncertainties,” said Jamie Goen, executive director of the trade group Alaska Bering Sea Crabbers, which represents harvesters.

Ecosystem-Based Fisheries Management Strengthens Resilience to Climate Change

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

Ecosystem-based fisheries management (EBFM) has been applied in Alaska for decades with great success. Alaska’s valuable commercial fisheries are among the most productive and sustainable in the world. However, current EBFM policies were not designed to address climate change.

A new study evaluates the future performance of EBFM in the eastern Bering Sea. The innovative experiment projects that EBFM can forestall climate-driven collapse of key Alaska fisheries better than other management policies. This management approach considers the impacts on fish stock productivity from environmental variables, such as changing ocean conditions, and socio-economic factors. It can help fishery managers and fishermen in planning for the future.

“Ecosystem-based management doesn’t just help fish, it helps fishing communities. It is the best strategy we have to provide harvest stability in the coming years. It buys time for Alaska fisheries and fishing communities to prepare and adapt. EBFM is going to be a vital tool for us under climate change,” said Kirstin Holsman, biologist at NOAA Fisheries’ Alaska Fisheries Science Center. “But no matter how effective management is, by mid-century—maybe sooner—Alaska fisheries may reach a tipping point of rapid decline in the eastern Bering Sea if climate change continues on the current trajectory and fish and fisheries are not able to adapt to these changing conditions. To guarantee long-term success, we need to couple EBFM with global climate change mitigation.”

The David And Goliath Story Playing Out In Alaska’s Fisheries

September 14, 2020 — One day in April 1991, a large fishing boat sliced through the cobalt waters of the North Pacific, not far from Sitka, Alaska, on its way to the Bering Sea. For some reason, perhaps to make sure its gear was in order, the boat dropped its weighted trawling net, dragging it across the ocean floor. As the boat drifted by, thousands of pounds of rockfish got scooped up in the mesh. Just like that, the local rockfish season was over.

“Outraged.” That is how Linda Behnken, a Sitka-based fisherman and director of the Alaska Longline Fishermen’s Association, described her reaction to news of the trawler’s nets rising from the ocean full of strangled or struggling fish, leaving the area’s fishing territory depleted. “It was a major catalyzing event.”

Facing the loss of a resource that had supported generations of fishing families, Behnken and the local community set out to protect the pristine waters of Southeast Alaska from the ravages of industrial fishing and banish trawling boats that drag wide nets to indiscriminately collect fish. A David to industrial fishing’s Goliath, Behnken was told to give up, that the cards were stacked against her. It took years of lobbying and rallying local support, but with the passage of the Southeast Alaska Trawl Closure in 1998, she had helped enact what at that time was the world’s largest ban on trawling, protecting 70,000 square miles of ocean habitat.

“The trawling ban is the reason we still have healthy small-scale fisheries in Southeast Alaska,” she said.

In the decades since, as the global fishing industry has consolidated into fewer, larger corporate fleets and environmental changes have threatened the ocean’s resources, Alaska’s Southeastern panhandle has emerged as a bastion for sustainable, small-scale fishing.

ALASKA: Harbor porpoise bycatch near Point Barrow contributes to larger study on Bering Sea population

September 4, 2020 — When James Judkins began pulling up his fishing nets out near Point Barrow this month, the weight of the catch pulled back at him.

“Man, this is a really big fish,” Judkins thought. Then, he glimpsed the dorsal fin. Then another. “Dolphins?” he wondered.

Close. Harbor porpoises, a marine mammal resembling dolphins, but in the same family as whales, have made several appearances in Utqiaġvik recently.

In recent weeks, local fishermen have caught at least four porpoises in subsistence fishing nets near Point Barrow. Judkins recovered two, along with a seal, on Aug. 12 in Elson Lagoon. The other two were bycatches in Christian Stein and Charlie Sikvaguyak’s separate nets set in the same area. For some fishermen, it was their first time seeing the mammal.

Pink Salmon May Benefit as Pacific Arctic Warms

September 1, 2020 — The following was released by NOAA Fisheries:

The Pacific Arctic is undergoing a rapid transformation. As temperatures rise and sea ice melts, some species will do better than others. A new study suggests that pink salmon may be one of those species.

“Our results suggest that warming is both increasing freshwater habitat and improving early marine survival of pink salmon in the northern Bering Sea,” said Ed Farley, NOAA Fisheries biologist at the Alaska Fisheries Science Center, who led the study.

The study provides insight into the response of pink salmon to climate change. The findings are valuable information for commercial and subsistence fisheries, and fishing communities, preparing for future changes.

“Subsistence harvesters would like to know what foods may be available to them now and into the future,” Farley said.

“The importance of fish in Arctic subsistence economies cannot be overstated; they are some of the most commonly eaten foods,” said coauthor Todd Sformo, biologist at the North Slope Borough Department of Wildlife Management.

“In the past on the North Slope, salmon have been used for dog food and even considered nuisance fish when interfering with preferred species such as aanaakliq or broad whitefish in the inland rivers. Recently, there seems to be a change both qualitatively and quantitatively in the use of salmon as a main dish and for smoking.

“Participating in this study allowed me to present a subsistence perspective, learn how fellow researchers measure production dynamics, and better understand how pink salmon are responding to climate warming in the northern Bering Sea. While this research is further south than the waters surrounding the North Slope, it is a beginning of our attempt to account for potential change in subsistence fishing.”

Alaska fishing communities feared getting COVID-19 from industry. They haven’t.

July 23, 2020 — As this year’s summer fishing season approached, local leaders across Alaska issued dire warnings about the thousands of plant workers and fishermen headed to their communities.

They feared the workers could bring COVID-19 in with them, quickly overwhelming small local hospitals and clinics. In Bristol Bay, home to the world’s largest sockeye salmon fishery, some residents called on Gov. Mike Dunleavy to cancel the season, citing the region’s traumatic experience with the 1918 pandemic flu, which killed at least 30% of its population.

In the month since the Bristol Bay season kicked off, some seafood companies have experienced isolated cases among workers in their processing plants. And other outbreaks have infected dozens of seafood workers elsewhere in the state — most recently, 85 crew members on board a Bering Sea factory trawler.

But midway through summer, with the Bristol Bay season winding down, seafood company executives and public health authorities can point to a remarkable fact: The industry has been almost completely successful in keeping its seasonal workers and fishermen from infecting Alaska residents.

“We haven’t seen any evidence of jumping the fence from the seafood industry to the community,” Bryan Fisher, a top state emergency response official, said in an interview earlier this month.

In the Bristol Bay Borough, home to the region’s largest concentration of fish processing plants, there have been dozens of cases of COVID-19 among nonresident seafood workers — but just one case among residents.

ALASKA: A fishing boat docked in Dutch Harbor with 85 COVID-19 cases

July 21, 2020 — More than two-thirds of the crew of a huge factory fishing vessel docked in the Aleutian fishing port of Dutch Harbor has tested positive for COVID-19, local authorities announced Sunday.

The 85 cases are on board the American Triumph, owned by Seattle-based American Seafoods — one of the biggest players in the billion-dollar Bering Sea pollock fishery.

The Triumph arrived in Unalaska/Dutch Harbor on Thursday, with seven crew members reporting symptoms consistent with COVID-19.

All seven were tested for the virus upon arrival, and six of those tests came back positive, officials announced Friday. That prompted staff from Unalaska’s clinic, Iliuliuk Family and Health Services, to test the remaining 112 crew.

All crew members were restricted to either the vessel or their isolation locations while in Unalaska, city officials said.

Pollock Survey Begins in Eastern Bering Sea

July 16, 2020 — The following was released by NOAA Fisheries:

For the past four decades, a team of scientists have conducted an acoustic trawl survey from a NOAA research vessel in the eastern Bering Sea. They collect acoustic measurements of fish abundance and distribution. They also sample fish by capturing them with trawl nets to groundtruth the acoustic signals to confirm the species. They also are able to learn more about the fish themselves—for example, their age, length, weight, and reproductive state.

Scientists believe using acoustic technology on saildrones to survey in the eastern Bering Sea will provide a reliable estimate of pollock abundance, based on past experience comparing the technology to ship-based surveys. It also helps that pollock are the dominant fish species in this area, minimizing the need to further sample with a trawl net to confirm species.

Since the standard surveys were cancelled this year due to COVID-19, data collected by the saildrones will fill a gap in the survey time series. Scientists use these survey data along with other data to assess pollock population abundance and trends (whether the stock is increasing or decreasing in size). The saildrone survey is expected to take two months to complete.

In late June, after some 40 days at sea, the three saildrones arrived at Unimak Pass, a 20-nautical-mile gap between Unimak Island and Ugamak Island that separates the North Pacific Ocean from the Bering Sea. At this point the saildrones separated. Each saildrone will cover a third of the 600-nautical-mile-wide survey area, which is bordered by Alaska’s Aleutian Islands to the south and the edge of the eastern Bering Sea shelf to the west.

The saildrones will complete a series of north-south transects moving from east to west; the mission is designed to mimic a typical ship survey as closely as possible in the amount of time available. Each vehicle is equipped with a Simrad EK80 high-precision split-beam echo sounder to map fish abundance.

No COVID-19 cases found on American Seafoods trawler in Alaska

June 18, 2020 — Health officials in Alaska found no cases of COVID-19 aboard an American Seafoods trawler that recently arrived in Dutch Harbor to fish for Bering Sea pollock. The ship, the Ocean Rover, docked in the Unalaska port on Sunday, 14 June, where, according to a press release from the city, local health officials worked together with American Seafoods to screen and test crewmembers.

“In a coordinated effort between the IFHS Clinic, City of Unalaska, State of Alaska Health and Social Services, and American Seafoods, all 121 members on board responded to health questionnaires and were tested for COVID-19 as warranted. Sixteen crew members were found to have possible symptoms of COVID-19 and were quarantined pending test results. All tests returned negative. The Ocean Rover is offloading frozen product and will return to sea,” the press release read.
