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.

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.

West Coast fishing communities’ vulnerability to climate change assessed in new study

April 17, 2020 — Climate change is warping the West Coast marine ecosystem. Warm waters are driving species north. Acidification and deoxygenation are threatening coastal species.

Fishermen are intimately familiar with these impacts. When the marine heat wave of 2014 and 2015 – dubbed “the Blob” – raised water temperatures for months on end, fishermen saw landing revenues of salmon and hake drop. That heat wave foreshadowed the increased and more severe heat waves that are likely to come.

Ray Hilborn is optimistic fishery management can work

April 9, 2020 — If you find it hard to imagine a college professor (of a subject other than epidemiology) drawing a crowd nowadays, I’m with you. Yet that is exactly what fisheries scientist Ray Hilborn did April 2.

To a sit-in-your-office, stare-at-your-monitor webinar, no less!

It’s conceivable that the size of the audience reflected a degree of covid-19-inspired restlessness. But ennui alone cannot explain the more than 450 people who signed up for Hilborn’s presentation on the status of fish stocks and the role of management. And rather than dwindle, as webinar audiences tend to do, by the time the session ended Hilborn’s audience had swollen to “an easy 600,” according to NOAA’s Tracy Gill, who coordinated the event.

To be fair, Hilborn was no stranger to his audience. A professor of aquatic and fishery science at the University of Washington, he’s written several books, including, most recently, “Ocean Recovery: A Sustainable Future for Global Fisheries” (co-authored by his wife, Ulrike Hilborn) as well as scores of peer-reviewed papers, and is respected by industry, academics, and NGOs.

His message Thursday was reassuring – more or less. Listen to scientists long enough, and you realize that you can get yourself into trouble reading between the lines.

Many of you, for example, will recall how in 2006, mainstream journalists leveraged a study led by the Canadian ecologist Boris Worm on the loss of biodiversity in ocean ecosystems services into the disappearance of fish by 2048. “One very small part of the paper,” Hilborn recalled, extrapolated from catch trends and came up with a downward curve that “hit the y axis,” in the professor’s words, at 100 percent collapsed in 2048.

First Long Term Acoustic Study Tunes Into Cook Inlet Beluga Whale Foraging Ecology

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

The first continuous multiyear acoustic monitoring effort across Cook Inlet provides the most comprehensive description of beluga whale seasonal distribution and feeding behavior to date.

This knowledge is critical for understanding and managing potential threats impeding recovery of this endangered population.

“Cook Inlet belugas were listed as endangered in 2008. Despite protective measures, the population continued to decline,” said Manuel Castellote, NOAA Fisheries affiliate/University of Washington/Joint Institute for the Study of the Atmosphere and Ocean biologist who led the study. “We undertook this study to provide information that managers needed to develop an effective recovery strategy.”

Castellote worked in partnership with the Alaska Department of Fish and Game to develop a passive acoustic monitoring program. It recorded beluga movements and foraging behavior within their critical habitat year-round over five years.

“Summer beluga distribution has been well studied, especially in the upper inlet. But information on foraging behavior during the rest of the year was basically nonexistent,” Castellote said. “That knowledge is essential to identify threats impeding the whales’ recovery.”

MAX MOSSLER: The truth behind seafood sustainability?

January 31, 2020 — People care about the impact of their diet. According to Nielson1, consumers are more likely than ever to acknowledge the environmental impact of global food production and make choices to reduce their individual footprint – usually willing to pay more for lower-impact foods. So why is seafood not flying off the shelves? It is, by far, the lowest impact animal protein2 and, according to a recent global analysis3, fish populations around the world are healthy in places that manage their fisheries well.

The problem is that people’s perception of ocean conservation and subsequent seafood sustainability is often misinformed. For example, when people are asked4 to rank ocean threats, pollution (like plastic) and overfishing are consistently listed as the top two despite expert consensus that climate change is the most pressing threat. The seafood industry has a largely negative5 reputation among everyday consumers and are increasingly blamed6 for plastic pollution.

Why does the negative perception of seafood persist?

Overfishing throughout the 1980s and 1990s earned the seafood industry its infamous label. High-profile media stories about overfishing coupled with the formation of several international ocean advocacy groups vilified the industry – a reputation the industry cannot seem to shake, despite important policy reforms and strong data that many global fisheries are firmly on a path to sustainability.

New Study Finds Some Fisheries Management Is Actually Working

January 30, 2020 — Understanding how many fish are in the sea is crucial to creating effective policy and management strategies. One study out of the University of Washington in Seattle took a close look at how fishing pressures and stock abundance are correlated. How will management initiatives in countries with high fishing pressure affect the number of fish that are available to catch? Ray Hilborn and 23 contributing authors on the paper took a data-driven approach to this question with optimistic results that they hope will convince policymakers and the public that fish stocks are actually on the rise.

Hilborn has been labeled an “overfishing denier” for his divisive views on the status of overfishing and his pushback against marine protected areas (MPAs), but Hilborn argues that closing areas to fishing is not necessarily the answer; “fisheries are not well managed in many parts of the world (the ones primarily where we did not have data for our paper)…our paper shows that fisheries management does work when implemented”. The researchers assessed fish catch data from six continents (which comprised about 50% of total global catch) up until the year 2016 and found that where fish stocks were being managed properly, increased number of fish was the result. “Our hope for the use of the results is that the thousands of scientists, managers and technicians that have helped stop overfishing will be recognized for their contribution”, Hilborn says.

Fish stock assessments use data gathered from a number of sources including fisheries landings (the fish that are caught by fishers and reported), biological studies and scientific surveys. While there are uncertainties in the data due to environmental, financial and technological limitations, stock assessments provide the backbone of fisheries management and drive regulatory decisions.

Fish populations around the world are improving

January 16, 2020 — The following was released by Sustainable Fisheries UW:

Let’s enjoy some unequivocal, inarguable good news: a paper published today in PNAS, Hilborn et al. 2020, shows that on average, scientifically-assessed fish populations around the world are healthy or improving. And, for fish populations that are not doing well, there is a clear roadmap to sustainability. With Australia on fire and scares of World War III, the start of 2020 and the new decade has been awful; hopefully Hilborn et al. 2020 can kickstart a decade of ocean optimism.

Hilborn et al. 2020 counters the perception that fish populations around the world are declining and the only solution is closing vast swaths of ocean to fishing. Instead, Hilborn et al. 2020 argues that increasing scientific, management, and enforcement capacity will lead to more abundant and sustainable oceans. The major takeaway of the paper is that fishery management works—when fisheries are managed, they are sustained. The key is following the science-to-management blueprint. Scientific data collection and fishery assessment comes first, then fishing regulation and enforcement of fishing policies. With the blueprint in place, most fisheries around the world are sustainable or improving.

The paper uses updates to the RAM Legacy Stock Assessment Database, a decades-long project to assemble data on fish populations that are scientifically assessed. As of 2019, the database contains data on 882 marine fish populations, representing about half of reported wild-caught seafood. In 2009, the database contained data on only 166, representing a much smaller proportion of global seafood. Researchers have spent the last 10 years adding to the database, and with today’s publication, update the global status of fish stocks. They found that, on average, fish populations are above target levels. Not every stock is doing well, but on average, things are much better than they were 2 decades ago. How nice: an environmental story where things are better now than they were in the past!

The paper describes the global status of fish stocks, but it also tells the story of fishery sustainability from the past 50 years.
