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  an animal can live,” said Deutsch. “You must consider : 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  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 —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.”

Warming Oceans Choke Fish as Habitats Get Less ‘Breathable’

May 20, 2020 — The cool, nutrient-rich water of the California Current supports a variety of marine life, including invisible phytoplankton, economically important salmon, rockfish, and Dungeness crab, and majestic orcas.

For the study in Science Advances, researchers used recent understanding of water breathability and historical data to explain population cycles of the northern anchovy. The findings for this key species could apply to other species in the current.

“If you’re worried about marine life off the west coast of North America, you’re worried about anchovies and other forage fish in the California Current. Ultimately it’s what underpins the food web,” says lead author Evan Howard, a postdoctoral researcher in oceanography at the University of Washington.

Researchers Probe Orca Poop for Microplastics: Part 1

May 19, 2020 — The following was released by NOAA Fisheries:

You might worry about your toddler chewing on a plastic toy with toxic chemicals. Some orca researchers are beginning to worry about whales ingesting a gut full of microplastics, and what that might mean for their health.

Microplastics are everywhere. Millions of tons of plastic enter our oceans annually, and much of it breaks into tiny pieces. Microplastics are plastic particles five millimeters (about two-tenths of an inch) or smaller. They represent 92 percent of plastic pieces polluting the oceans’ surface waters. Researchers have found microplastics in all major seas and oceans. They’ve also found them in the intestinal tracts of organisms at all levels of the ocean food chain, from zooplankton to fish to marine mammals.

Some scientists are concerned that microplastics and their toxic effects are bioaccumulating in killer whales, the oceans’ top predators. Endangered Southern Resident killer whales spend much of their summers in Puget Sound and the Salish Sea. Chemical contamination from pollution, particularly in young whales, is one of three primary threats to their population. Could microplastics be part of the problem?

A team of scientists with NOAA Fisheries’ Northwest Fisheries Science Center (Center) and the University of Washington have started an investigation. They are looking at what microplastics the Southern Residents are ingesting, at what scale, and whether the whales are being exposed to toxic chemicals associated with microplastics.
