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.

ALASKA: Bering Sea commercial fleets taking extra precautions during pandemic

April 15, 2020 — Commercial fishermen who have embarked on the Bering Sea for the 2020 season are taking extra precautions in light of the COVID-19 pandemic that has moved much of the world into isolation.

According to a report from The Bristol Bay Times, Bering Sea snow crabbers who are still out working the waters have been confined to their boats while making deliveries to processing plants. They’ve also been urged to avoid contact with plant workers to help prevent any potential spread of the deadly virus, the Intercooperative Exchange’s Jake Jacobson told The Times.

Abnormally Warm Years Caused a Sea Change in Coastal Alaska Ecosystems

February 27, 2020 — Rapidly warming Alaska is already a poster child for climate change, from its vanishing sea ice to its thawing permafrost. But over the last three years, the state’s northwestern coast has experienced a series of unusual climate-related changes—remarkable even for the long-altered Pacific Arctic.

Beginning in 2017, a combination of abnormally high temperatures and unusually strong, southerly winds swept the Bering and Chukchi seas. An alarming cascade of ecological consequences ensued—record-low sea ice, shifting algae blooms, migrating fish populations and sudden seabird die-offs were just a few.

“Most of my own research is with people living in the coastal communities, so talking to them and hearing about what they’re seeing,” said Henry Huntington, an independent Alaskan researcher and consultant. “And they saw some very unusual things, and things that struck them.”

“Ridiculous” water temperatures and unstable sea ice were among the most common complaints raised in interviews with coastal residents, Huntington noted.

“Adding to that, what we’re hearing from folks on the research cruises, it just became apparent that things were really a lot different from what any of us expected,” he said.

Alaska governor’s budget proposal would trim some fishery programs

February 3, 2020 — Cuts proposed by Alaska governor Mike Dunleavy to his state’s Department of Fish and Game (ADF&G) next fiscal budget could be felt in a number of commercial fisheries, reports Alaska Fish Radio‘s Laine Welch.

Dunleavy, a Republican elected in 2018, has proposed nipping $1 million next year from the agency’s nearly $67m budget, of which $36m comes from state general funds, according to Welch.

That would mean the closure of an office in Southeast Alaska and the elimination of red king crab assessments. Cuts also are on deck for stock assessments for Southeast urchin and sea cucumber fisheries, which will likely reduce dive time, Welch reported.

Sinking of crab boat comes after decades-long push to improve safety of commercial fishing

January 6, 2020 — The sinking of the crab boat Scandies Rose, which left five crew members presumed dead off the Alaska Peninsula on New Year’s Eve, comes after a decades-long push to make commercial fishing in Alaska safer. Regulation changes have helped drive more safety measures for the historically lucrative industry, but some dangers remain inherent, said Scott Wilwert, the commercial fishing vessel safety coordinator for the Coast Guard in Alaska.

“The hazards are endless,” Wilwert said. Equipment, distance from other boats and harrowing weather all pose dangers.

The sinking of the 130-foot Scandies Rose sent a shock wave through Alaska’s commercial fishing industry, especially among those in the relatively small group that fishes the Bering Sea and Gulf of Alaska.

Greg Alexander, a veteran of those waters, was a close friend of Scandies Rose captain Gary Cobban Jr. He said Cobban Jr. was a “first-class” captain with a sterling safety reputation who ran with an experienced crew.

Adak, Groundfish Trawlers at Odds on P-Cod Processing

December 18, 2019 — Pacific cod stocks hard hit by warming ocean temperatures are becoming a focal point at federal fisheries meetings, where harvesting sectors and processors fight over who gets to catch and process this versatile vitamin and protein packed white fish.

Stock assessments in the fall of 2019 put the population of P-cod in the Gulf of Alaska below the federal threshold that allows for commercial harvest, for the benefit of endangered Steller sea lions who rely on them as a food source.

The Gulf cod fishery was cancelled. The Bering Sea/Aleutian Islands TAC was cut from 24,319,000 metric tons in 2019 to 22,000 metric tons for 2020.

The lower quota is intensifying the race for fish, and a fight between the trawlers and the community of Adak, Alaska, over where that fish will be processed.

At the heart of the battle is Amendment 113 to the fishery management plan for BSAI groundfish. This amendment set aside a portion of the Aleutian Islands cod fishery TAC for harvest by vessels directed fishing for Aleutian Islands Pacific cod and delivering their catch for processing to a shoreside processor located on land in Adak. The 5,000 metric tons P-cod harvest set-aside was designed to provide the opportunity for vessels, Aleutian Islands shore plants and communities where Aleutian Islands shore plants are located to benefit from the P-cod fishery.

Climate Change Hitting Top U.S. Fishery in the Arctic: NOAA

December 11, 2019 — Climate change is causing chaos in the Bering Sea, home to one of America’s largest fisheries, an example of how rising temperatures can rapidly change ecosystems important to the economy, U.S. federal government scientists said in a report on Tuesday.

Rising temperatures in the Arctic have led to decreases in sea ice, record warm temperatures at the bottom of the Bering Sea and the northward migration of fish species such as Pacific cod, the U.S. National Oceanic and Atmospheric Administration, or NOAA, said in its 2019 Arctic Report Card.

While the changes are widespread in the Arctic, the effect on wildlife is acute in the eastern shelf of the Bering Sea, which yields more than 40% of the annual U.S. fish and shellfish catch.

“The changes going on have the potential to influence the kinds of fish products you have available to you, whether that’s fish sticks in the grocery store or shellfish at a restaurant,” said Rick Thoman, a meteorologist in Alaska and one of the report’s authors.
