NMFS reports fishing revenue crashed 29 percent in pandemic

January 19, 2021 — The U.S. fishing industry lost nearly one-third of its revenue in the first seven months of 2020 as the covid-19 pandemic vaporized its major markets, according to a new analysis by NMFS.

The year started on a high note, with revenues up 3 percent in January and February – before diving 19 percent in March and cratering at 45 percent less in July, said Paul Doremus, deputy administrator for operations at NMFS, in a telephone conference with reporters Friday.

Cumulatively, “over those seven months we’re looking at a 29 percent decrease,” said Doremus.

The agency mobilized its economic experts and government and academic partners in March to document the impact of the pandemic and begin preparing “as comprehensive an account as we could,” said Doremus.

The findings were compiled in a report with more than 100 pages of supporting documents, including detailed region-by-region breakdowns, by authors and economists Rita Curtis of the NOAA Fisheries Office of Science & Technology and Steve Kasperski of the agency’s Alaska Fisheries Science Center.

While the report only documents the industry’s situation up through July, “we’ve already initiated the work to do that next update,” said Curtis. The goal is to continue monitoring economic impacts and fishermen’s response, drawing lessons and strategies for making fishing communities more resilient, said Doremus.

Distribution and Abundance of Forage Fish in Arctic and Sub-Arctic Waters Affected by Warming Ocean Conditions

January 14, 2021 — The following was released by NOAA Fisheries:

Pelagic or forage fish species are an important source of food for marine predators in the eastern Bering Sea. This group of fish includes capelin, Pacific herring, juvenile chum salmon, juvenile pink salmon, juvenile sockeye salmon, and walleye pollock during their first year of life.

A new study by scientists at the Alaska Fisheries Science Center shows variable effects on species distribution and abundance. It looked at several warm periods from 2002–2018 when ocean temperatures were warmer than average for four or more consecutive years.

Previous studies by NOAA Fisheries documented a northward shift in age-0 pollock, juvenile salmon, herring, and capelin during the 2002-2005 warm period relative to the 2006-2011 cool period in the eastern Bering Sea.

“However, this is the first study to look at temperature-related changes in the distribution and biomass (total average weight of all fish) of pelagic fishes over multiple warm periods,” said Ellen Yasumiishi, researcher, Alaska Fisheries Science Center and lead author for the study. “Studies like this are also important for understanding factors that may affect juvenile salmon and age-0 pollock growth, development and ability to reach maturity. As adults these fish are targeted by commercial, recreational, and subsistence fisheries in Alaska.”

ALASKA: Some Fishermen on Edge After Rough Year in North Pacific

January 6, 2021 — Some fishermen in the North Pacific Ocean are on edge ahead of a traditionally fruitful winter fishing season, following a rough 2020 that saw catch rates fall below long-term averages.

The coronavirus pandemic forced the cancellation of some research surveys, making it more difficult to determine how many fish are in the Bering Sea off Alaska, the Seattle Times reported Monday.

The Seattle-based Alaska Fisheries Science Center canceled five of six research missions that help scientists measure fish stocks because of fears of virus outbreaks at sea.

Fishermen have begun their two-week coronavirus quarantines ahead of the Jan. 20 start of the fishing season and aren’t sure what they’ll find once ships largely based in Washington state make their way to the Bering Sea.

“This is the best time of year,” said Kevin Ganley, who captains a 123-foot (37-meter) boat called American Beauty. “If (the fish) are not there, we’re in trouble.”

Due to COVID-19, Drone Survey Powers NOAA’s Bering Cod Assessment

December 30, 2020 — Every other year, NOAA Fisheries conducts an acoustic-trawl survey from crewed research vessels to measure pollock abundance in Alaska’s eastern Bering Sea. As a result of COVID-19, many research surveys were canceled, and we weren’t able to conduct our walleye pollock surveys. Data collected from these surveys are critical to manage pollock, which comprise the nation’s largest commercial fishery.

NOAA Fisheries scientist Alex De Robertis at the Alaska Fisheries Science Center developed a contingency plan: conducting the survey with saildrone wind- and solar-powered ocean-going robots. The hope was to collect some data despite the vessel survey cancellation.

For the past several years, De Robertis and colleagues at the Alaska Fisheries Science Center have been working with partners at NOAA Research’s Pacific Marine Environmental Laboratory,  Saildrone and Kongsberg. They use uncrewed surface vehicles equipped with low-power sonar (acoustic) sensors to conduct research in the Bering and Chukchi Seas. The pollock survey contingency plan was an opportunity to apply what they had learned to collect data for resource management.

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.

Russian and American Scientists say warming water is pushing Bering Sea pollock into new territory

November 20, 2020 — In a new study, scientists have linked warming Arctic temperatures, changing wind patterns and shifting currents to movement of commercially valuable Alaska pollock in the Bering Sea.

The Bering Sea has seen the loss of a summer cold water barrier in recent years, which used to keep pollock from spreading out and moving north.

But while scientists are seeing drastic shifts in pollock movement patterns, further research needs to be conducted to know what the changes mean for communities like Unalaska and Dutch Harbor and the billion-dollar pollock industry.

“This research is really critical because pollock are a key ecological component of the Bering Sea shelf food web supporting the largest commercial fishery in the U.S. by biomass,” said Robert Foy, NOAA’s Alaska Fisheries Science Center director. “To get an accurate assessment of pollock abundance so that resource managers can set sustainable catch limits, we have to be able to understand pollock distribution, which certainly looks different under a warm water regime.”

ALASKA: Seafood Bycatch Donation Relieves Hunger and Reduces Waste

November 2, 2020 — The following was released by NOAA Fisheries:

Fishermen sometimes unintentionally catch fish they do not want or cannot keep. This is called bycatch. While these fish are returned to the sea, many of them do not survive. This is a major problem worldwide—nearly 10 percent of global fishery catches are discarded each year

This waste of valuable seafood protein has been an increasing focus of management, industry, and public concern due to its ecological and economic impacts. That’s where our innovative donation program comes in.

Alaska fishermen occasionally catch Pacific halibut and salmon incidentally in trawls targeting groundfish. Because halibut and salmon are valuable targets of other fisheries, they are designated as prohibited species. Groundfish trawlers are not allowed to retain or sell them. Historically, all prohibited species caught in Alaska were discarded at sea to avoid any incentive to catch these species.

The North Pacific Fishery Management Council and the Alaska seafood industry have a long history of cooperative efforts to reduce bycatch. However, even after bycatch has been eliminated to the extent practicable, some is inevitable.

In 1996, NOAA Fisheries and the North Pacific Fishery Management Council established the Prohibited Species Donation Program. It takes a unique approach to the problem of discarded fish by making it possible for fishermen to donate some bycatch to hunger relief organizations. It simultaneously reduces waste, provides high quality seafood protein to people in need, and avoids incentives to catch prohibited species.

“Bycatch donation is an example of thinking outside the box. When we think about reducing waste, it is usually about avoiding bycatch. This program is a creative solution to maximize the value of the bycatch that can’t be avoided,”  said Jordan Watson, NOAA Fisheries biologist at the Alaska Fisheries Science Center.

Wind Influences Pollock Success in the Gulf of Alaska

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

For young Alaska pollock in the Gulf of Alaska, survival may depend on which way the wind blows.

A study conclusively shows for the first time that year-to-year variation in the geographic distribution of juvenile pollock in the Gulf of Alaska is driven by wind. Depending on wind direction, water movement may retain juvenile fish in favorable nursery habitats, or transport them away. Young fish that are transported to less favorable habitats are less likely to contribute to year-class strength— the abundance of adults available to the valuable Gulf of Alaska pollock fishery.

For NOAA Fisheries biologist Matt Wilson of the Alaska Fisheries Science Center, the new study addressed a longstanding question.

“When we began this research, scientists thought that lots of juvenile fish would mean a relatively strong adult year-class. But in some years our surveys found a lot of juvenile pollock, followed by a weak year class. In other years a high number of juveniles grew into a strong year class,” Wilson said. “We undertook this research to better understand why large numbers of juveniles do not always translate into a high abundance of adults.”

Wilson and co-author Ned Laman also observed that the geographic distribution of juveniles was highly variable from year to year. In some summers, a very large proportion of the juvenile population was far southwest of the main spawning grounds.

“In this study we asked: what is the cause and consequence of year-to-year geographic variability in the distribution of juvenile pollock in the Gulf of Alaska?” Wilson said.

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.”

Fishing Families and Women in Alaska’s Fisheries

August 24, 2020 — The following was released by NOAA Fisheries:

Over recent decades, Alaska’s fisheries have undergone many regulatory, environmental, social, and economic changes, which have differentially affected dynamics in fishing families. Researchers from the Alaska Fisheries Science Center explored these changes and their effects on fishing families in a series of focus groups held throughout Gulf of Alaska fishing communities in 2017 and 2018. These focus groups covered three topics examining family roles and gender division of labor; impacts of management, environmental, economic and social conditions on these roles; and, the future of fishing families and women in Alaska’s fisheries. The research demonstrates the integral work of women in fishing families and their dynamic roles in Alaska’s fisheries more broadly. It further showcases how fishing families have, and continue to, adapt to multifaceted conditions in Alaska’s fisheries. This research has resulted in several scientific journal publications and web stories (which are available below), and is an ongoing effort to document novel conditions, adaptations, and resilience.

Thanks to Sarah Marrinan, North Pacific Fishery Management Council staff, for help with conducting these focus groups.
