Use of ocean resources changed as Dungeness crab fishing industry adapted to climate shock event

January 6, 2021 — An unprecedented marine heat wave that led to a massive harmful algal bloom and a lengthy closure of the West Coast Dungeness crab fishery significantly altered the use of ocean resources across seven California crab-fishing communities.

The delayed opening of the 2015-16 crab-fishing season followed the 2014-16 North Pacific marine heat wave and subsequent algal bloom. The bloom produced high levels of the biotoxin domoic acid, which can accumulate in crabs and render them hazardous for human consumption.

That event, which is considered a “climate shock” because of its severity and impact, tested the resilience of California’s fishing communities, researchers from Oregon State University, the University of Washington and National Oceanic and Atmospheric Administration’s Northwest Fisheries Science Center found.

The study is the first to examine impacts from such delays across fisheries, providing insight into the response by the affected fishing communities, said James Watson, one of the study’s co-authors and an assistant professor in OSU’s College of Earth, Ocean, and Atmospheric Sciences.

Dungeness Crab Fishing Industry Response to Climate Shock

January 5, 2021 — The following was released by NOAA Fisheries:

Fishermen contend with regulations, natural disasters, and the ups and downs of the stocks they fish, along with many other changes. As a result, fishing communities are quite resilient. That is, they can withstand, recover from, and adapt to change.

But how much pressure can they stand? The 2014–2016 North Pacific marine heatwave, known as the Blob, led to a harmful algal bloom of unprecedented scale. It necessitated substantial delays in the opening of the 2015–16 U.S. West Coast Dungeness crab fishery. The fishery is vital to West Coast communities. It produces around 26 percent of all annual fishing revenue and supports more than 30 percent of all commercial fishing vessels.

Understanding Impacts from Climate Shocks

Previous studies have documented the devastating economic impacts from the 2015–16 event on Dungeness crab fishermen. Members of affected coastal communities attest that these socioeconomic effects rippled through associated industries and coastal communities. But can changes in fishing practices in response to this significant climate shock be quantified?

“We wanted to examine the extent to which the Dungeness crab fishery delays affected participation in other fisheries, and the duration of those changes,” said Mary Fisher, a doctoral student at the University of Washington. Fisher did the work as a National Science Foundation Graduate Research Internship Program Fellow at NOAA’s Northwest Fisheries Science Center.

Fisher and her colleagues at NOAA Fisheries, University of Washington, and Oregon State University studied the impacts on more than 2,500 vessels across seven California fishing communities. The researchers wanted to see how a climate-related shock (like the heatwave and associated harmful algal bloom) can impact communities’ use of ocean resources.

US seafood industry flounders due to COVID-19

November 24, 2020 — The global pandemic is hurting the seafood industry, and American fishmongers may flounder without more government aid, according to the largest study of COVID-19’s impacts on U.S. fisheries.

The new study, published Nov. 23 in the journal Fish and Fisheries, found that monthly fresh seafood exports declined up to 43% compared to last year, while monthly imports fell up to 37%, and catches dropped 40% in some months.

Additionally, over the first six months of 2020, total U.S. seafood exports were down 20% and imports were down 6%, compared to the same period last year. Further losses are likely as restrictions increase to address COVID-19.

“Seafood has been hit harder than many other industries because many fisheries rely heavily on restaurant buyers, which dried up when the necessary health protocols kicked in,” said lead author Easton White of the University of Vermont. “Restaurants represent about 65% of U.S. seafood spending, normally.”

For context, over one million U.S. seafood workers regularly produce more than $4 billion in annual exports, much of which is processed overseas and imported back to the U.S.

While seafood data often takes several months — or longer — to compile, the research team, including Trevor Branch of the University of Washington, used pioneering methods to quickly determine the pandemic’s impacts on fisheries. U.S. Congress received preliminary data from the study in September.

Marine animals live where ocean is most breathable, ranges may shrink with climate change

September 17, 2020 — As oceans warm due to climate change, scientists are trying to predict how marine animals—from backboned fish to spineless jellyfish—will react. Laboratory experiments indicate that many could theoretically tolerate temperatures far higher than what they encounter today. But these studies don’t mean that marine animals can maintain their current ranges in warmer oceans, according to Curtis Deutsch, an associate professor of oceanography at the University of Washington.

“Temperature alone does not explain where in the ocean an animal can live,” said Deutsch. “You must consider oxygen: how much is present in the water, how well an organism can take up and utilize it, and how temperature affects these processes.”

Species-specific characteristics, overall oxygen levels and water temperature combine to determine which parts of the ocean are “breathable” for different ocean-dwelling creatures. New research led by Deutsch shows that a wide variety of marine animals—from vertebrates to crustaceans to mollusks—already inhabit the maximum range of breathable ocean that their physiology will allow.

Stuck at home? Here’s a fine way to find fish

September 17, 2020 — Between 85% and 90% of all seafood is consumed in restaurants or purchased from retail stores. So when COVID-19 struck in March, the seafood industry went into shock.

Gone were the restaurants that bought millions of pounds of seafood, including our beloved salmon, a mainstay of Pacific Northwest good eating. In 2017, for instance, Washington state’s total commercial catch was 666 million pounds—and that’s just one state’s catch.

Into this desperate situation stepped Max Mossler, ’16, managing editor and developer of Sustainable Fisheries, an entity of the UW School of Aquatic and Fisheries Sciences that explains the science of sustainable seafood. Mossler developed a Fish Map from information he collated from hundreds of commercial fishing lists. The map is a way for commercial fishing companies to sell their products directly to consumers. Want some fresh fish? Visit the website and tap one of the balloons on the map to see the name of the fishing enterprise and the type of fish on the “menu.”

ALASKA: Why biologists fear Pebble could risk Bristol Bay salmon’s resilience

August 3, 2020 — The U.S. Army Corps of Engineers’ final environmental review of Pebble says that under normal operations, it does not expect the mine to have a significant effect on fish populations in Bristol Bay. But the Corps does say the mine would harm fish around the mine site. Some scientists say the project could also put a specific salmon population in the Koktuli River at risk and remove genetic diversity from the region.

The mine would be built at the headwaters of the Koktuli River drainage, and it would eliminate about 20% of available habitat there, though the Corps says that does not necessarily represent fish habitat.

Daniel Schindler has spent decades studying salmon in the Bristol Bay watershed. He’s a professor of fisheries sciences at the University of Washington

“If you looked at the Koktuli all by itself, and you assumed that all sockeye salmon are interchangeable across all of Bristol Bay, then you would say that the Koktuli River is a very small piece of habitat, and it’s not that important,” he said.

According to Schindler, the variety of different life strategies and genetic identities of sockeye throughout Bristol Bay ultimately stabilizes the returns of fish back to the rivers every year.

The COVID-19 Slowdown Will Show Whether Quieter Seas Help Killer Whales

June 30, 2020 — Deborah Giles and her dog are on a mad search for floating poop. Killer whale poop, to be precise.

Giles, a killer whale biologist at the University of Washington’s Center for Conservation Biology, is cruising the Strait of Juan De Fuca, a roughly 15-mile-wide inlet between Canada’s Vancouver Island and Washington state. The coastal waterway is a hotspot for migrating killer whales. Lately, the waters have been calmer and quieter because of boating and border restrictions enacted in the wake of COVID-19. That is why Giles has brought her scat-tracking dog, Eba, who will sniff the air as the boat cruises then start licking her lips, whining, and barking as they get closer to killer whale excrement.

These buoyant, information-rich fecal samples ready for collection. Giles wants to know if the hushed waters are helping whales relax. “It’s just such a novel situation where we just don’t have people going out on their boats,” she says. “It’s markedly different.”

International Fishery Experts Agree on Key Area-Based Management Concepts

June 22, 2020 — The following was released by the Western Pacific Regional Fishery Management Council:

Area-based management has become a an international focal point for fisheries management with the United Nations advocating for some form of protected area in 30% of the ocean by 2030.

In response to this initiative and other issues, 34 fishery science and management experts from intergovernmental and nongovernmental agencies, regional fishery management organizations and academia convened by teleconference June 15-17 as a first step toward the development of a “Roadmap to Effective Area-Based Management of Blue Water Fisheries.” The workshop addressed emerging issues in national waters and in areas beyond national jurisdiction and called for clarity in objectives, monitoring and area-based selection. It also stressed comparing static vs dynamic area-based approaches.

The participants agreed that simply closing large sections of the ocean is not a silver bullet for managing blue water fisheries and their ecosystems and that marine protected areas (MPAs) are merely a single element within the tool box of area-based management.

“Area-based management tools are not exclusively MPAs or closures,” noted Ray Hilborn, professor at the School of Aquatic and Fishery Sciences, University of Washington.

Convened by the Western Pacific Regional Fishery Management Council and co-chaired by Hilborn and Vera Agostini (UN Food and Agriculture Organization), the workshop included participants from the Americas, Australia/Oceania and Europe. Workshop contributors addressed the application of area-based management tools to reach objectives pertaining to sustainable food production (local and global), employment (local and global), economic health and welfare, communities and culture, protected and non-target species, ecosystem integrity and resilience to climate change and other stressors.

Area-based management may be static in nature (i.e., have a fixed spatial delineation) or dynamic, whereby portions of the ecosystem closed to fishing can change in space and time. The workshop called for clarity in objectives, monitoring and area-based selection and comparing static vs dynamic area-based approaches.

Participants pointed out that with rapidly emerging technologies to collect data and monitor fisheries, area-based management can be adaptive and more precise in its implementation. But these objectives and management capabilities are also linked with specific need for empirical evidence and research.

“We can’t really predict the impacts of many actions because of information gaps,” Hilborn said.

Stakeholders and leading scientists cautioned for clear planning on the use of area-based management tools in blue water ecosystems rather than strictly opportunistic or “set it and forget it” implementation. Highly migratory fish movements are dynamic and their distributions are often moving, so scientific evaluation in planning is critical.

“Economic, cultural and social objectives need to be considered thoroughly prior to implementation of area-based management, and industry engagement is critical,” noted Craig Severance, professor of anthropology emeritus, University of Hawai’i at Hilo.

Alternative management measures should be explored and evaluated alongside any area-based management measures considered, including take MPAs, the participants agreed.

The workshop will produce the “Roadmap” document by the end of 2020 for publication as peer-reviewed literature.

New Map Launching Today Helps People Find Local Seafood

May 28, 2020 — The seafood industry relies heavily on restaurants and retail stores for the majority of sales. With restaurant closures and coronavirus shelter-in-place orders, the seafood industry has been hit hard. The sudden drop in demand has forced fishers and fish farmers to get creative in their methods, turning to direct sales to stay afloat. A new tool through the University of Washington Sustainable Fisheries initiative has compiled information about where to find seafood in the form of a map that can be used to easily track down local, sustainable catch for delivery or direct sales.

The goal of the map is to support small seafood businesses by making their transition to direct sales just a little bit easier. Generally a supplier (fishing boat or farm) will deal with processors and distributors to sell their fish, and customers will purchase through a restaurant or grocery store.

Now that direct sales are the only option, the industry is scrambling to keep up and adapt to a new way of business and the map is meant to shoulder some of the burden. “They’re bringing in people from sales to pack boxes, the last thing they should have to worry about is finding new markets,” says Jack Cheney; a senior project manager at seafood sustainability organization FishWise, and contributor for Sustainable Fisheries UW, a grant-funded website dedicated to explaining the science of seafood, “this is the least we can do to try and promote them in some small way.”

THE SEATTLE TIMES: New UW consortium will lead to a broader, deeper study of ocean health

May 28, 2020 — The University of Washington’s selection to host a new research consortium is a testament to the school’s well-earned reputation. It will help advance understanding of climate, ocean dynamics and marine ecosystems, building on the school’s track record of excellence in the field.

The National Oceanic and Atmospheric Administration announced last week that the UW will lead a new Cooperative Institute for Climate, Ocean, and Ecosystem Studies, which includes Oregon State University and University of Alaska Fairbanks. The designation comes with up to $300 million in funding for research into areas such as climate and ocean variability, the impacts of climate change on marine ecosystems, aquaculture and polar studies, in conjunction with the NOAA labs.

The selection is a testament to the UW’s research prowess: The commitment is nearly triple the last NOAA Cooperative Institute award to UW and formalizes longstanding collaborations among researchers along the West Coast.
