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.

COVID-19 forces cancellation of annual Alaska fish and crab surveys

June 10, 2020 — Surveys of Alaska’s fish, crab and halibut stocks in the Bering Sea have been called off or reduced due to constraints and dangers posed by the coronavirus.

In what they called an “unprecedented” move, the fisheries division of the National Oceanic and Atmospheric Administration announced in late May that five Alaska surveys will be canceled this summer “due to the uncertainties created by the COVID-19 pandemic, and the unique challenges those are creating for the agency.”

NOAA said in a statement it found “no way to move forward with a survey plan that effectively minimizes risks to staff, crew, and the communities associated with the surveys.”

The annual surveys are the cornerstone of Alaska’s sustainable fisheries management and provide data on how fish stocks are trending, where they are and, ultimately, how much will be allowed for harvest each year.

New Modeling Approach Provides Valuable Insights into the Important and Complex Role of Environmental Variables in Juvenile Fish Survival

May 29, 2020 — The following was released by NOAA Fisheries:

Variation in the productivity and sustainability of fish resources is determined, in part, by large changes in juvenile fish production from year to year. This is defined as “recruitment.” Fisheries oceanographers and fish stock assessment scientists have been trying to better understand and predict this variation for more than 100 years.

“We are seeing a lot of changes in the Bering Sea ecosystem. With analytical tools like this, we should be able to quickly identify factors affecting juvenile fish survival in a given year to generate reliable estimates of future productivity. This may help resource managers to more effectively target their management efforts,” said Jim Thorson, Habitat Ecological Processes Research Program Lead, Alaska Fisheries Science Center and lead author for the paper.

For the first time, scientists glimpsed how ocean temperature in different parts of Alaska’s Bering Sea may have influenced juvenile fish survival over the past three decades. They also gained valuable insights into how it may be affected under warmer ocean conditions in the future.

This unique approach combines oceanographic data collected from research surveys (1982-2018) with recruitment data into a single model. It also incorporated end-of-century projections of bottom and sea surface temperatures for the eastern Bering Sea. Scientists then used global climate models to develop regional-scale projections.

The authors see this an important step to understand the complex relationship between fish stock production and long-term climate processes. The ongoing collection of biological and environmental data will help to further improve these predictions.

NOAA Cancels Five Large-Scale Fishery Surveys Due to COVID-19

May 26, 2020 — NOAA Fisheries announced Friday that it will cancel five out of its six large-scale research surveys in Alaskan waters this year due to COVID-19. The canceled surveys include 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 is not affected.

“We determined that there is no way to move forward with a survey plan that effectively minimizes risks to staff, crew, and the communities associated with the surveys. For instance, conducting the key groundfish and crab surveys in a limited timeframe would require extraordinarily long surveys, well beyond standard survey operations,” wrote NOAA Fisheries in a statement. “Extended quarantines for the survey team prior to and following surveys would also be necessary to ensure survey team and public health and safety.”

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.
