Warm Water Important for Cold-water Fish Like Salmon and Trout, Study Finds

March 26, 2021 — The following was released by NOAA Fisheries:

Warm river habitats appear to play a larger-than-expected role in supporting the survival of cold-water fish, such as salmon and trout. This information was published today in a new study in the journal Nature Climate Change.

The research has important implications for fish conservation strategies. A common goal among scientists and policymakers is to identify and prioritize habitat for cold-water fish that remain suitably cool during the summer. This is especially important as the climate warms.

Potential Blind Spot

“Prioritizing cold-water habitat devalues seasonally warm areas, even if they are suitable for fish most of the year,” said Jonny Armstrong, lead author of the paper and an ecologist at Oregon State University. He called this a “potentially severe blind spot for climate change adaptation.”

A huge challenge for conservation is to figure out how to help these fish survive a warmer future. Typically, efforts focus on saving the coldest places, such as high mountain streams, which are already the most pristine parts of basins. This approach often neglects the places that are warm in summer, forgetting that these places are optimal for much of the year.

“We’re talking about a subtle shift in how we think about these thermal habitats,” said Aimee Fullerton, a fisheries biologist at NOAA’s Northwest Fisheries Science Center and a study co-author. “Of course, we want to protect the high-quality cold-water habitats. But we need to expand our definition of high-quality habitat to include some warmer waters.”

White House appoints former NOAA leader Jane Lubchenco to key climate change role

March 23, 2021 — The White House has appointed Jane Lubchenco, a well-known marine scientist at Oregon State University and former head of the National Oceanic and Atmospheric Administration, to a high-level position coordinating climate and environmental issues within its Office of Science and Technology Policy (OSTP).

The announcement scheduled for Friday marks another step in the Biden administration’s all-of-government approach to tackling climate change.

Lubchenco is serving in the renamed position of deputy director for climate and the environment, which in previous administrations had been known as the head of “energy and the environment.” The renaming signifies the emphasis the Biden Administration is placing on climate change.

Lubchenco’s portfolio encompasses a broad set of issues that President Biden asked OSTP officials to address in a letter on Jan. 15. In the letter to Eric Lander, nominated to serve as presidential science adviser, Biden tasked OSTP with finding climate change solutions that will help improve the economy and health, “especially in communities that have been left behind.”

OREGON: Crab fishery adapts following climate shock event

March 10, 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.

OSU researcher leads NOAA-funded project to study West Coast response to ocean acidification

March 4, 2021 — The following was released by Oregon State University:

An Oregon State University researcher is part of a new federally supported project investigating how communities along the West Coast are adapting to ocean acidification, with the goal of determining what they need to be more resilient.

Ana K. Spalding, an assistant professor of marine and coastal policy in OSU’s College of Liberal Arts, is leading a team looking into how shellfish industry participants in several towns along the Oregon and California coasts are responding to ocean acidification and where gaps in policy or resources have left them vulnerable.

The $1 million, three-year interdisciplinary project is funded by the National Oceanic and Atmospheric Administration (NOAA) through its Ocean Acidification Program. At OSU, Spalding is working with Erika Wolters, assistant professor of public policy, and Master of Public Policy students Victoria Moreno, Emily Griffith and Ryan Hasert.

“The goal of this project is to better align policy responses with the immediate and very local needs of shellfish-reliant communities,” Spalding said. “This is both understanding that vulnerability and proactively thinking, ‘What can we do to respond to better support members of the shellfish industry and their needs?’”

Ocean acidification and its impact on shellfish first became a major concern for West Coast farmers after a 2007 mass oyster larvae die-off at the Whiskey Creek Shellfish Hatchery in Netarts Bay, Oregon. OSU scientists definitively linked that die-off to increased carbon dioxide in the water in a 2012 study.

Researchers demonstrate new method to track genetic diversity of salmon and trout

February 19, 2021 — Scientists at Oregon State University and the U.S. Forest Service have demonstrated that DNA extracted from water samples from rivers across Oregon and Northern California can be used to estimate genetic diversity of Pacific salmon and trout.

The findings, just published in the journal Molecular Ecology, have important implications for conservation and management of these species, which are threatened by human activities, including those exacerbating climate change.

“There has been a dearth of this kind of data across the Northwest,” said Kevin Weitemier, a postdoctoral fellow at Oregon State and lead author of the paper. “This allows us to get a quick snapshot of multiple populations and species all at once.”

In addition to demonstrating that environmental DNA, or eDNA, can be used to measure genetic diversity, the researchers also made unexpected discoveries about the history of these species, including a connection that links watersheds in northern and southern Oregon.

As the world’s population grows, researchers say the ocean and seafood have big roles to play

August 27, 2020 — Seafood production could see as much as a 75 percent leap over the next three decades if certain policy reforms and technological improvements are put in place, according to research conducted by Oregon State University (OSU) in collaboration with a bevy of international scientists.

By 2050, the earth’s human population is expected to reach 9.8 billion, an increase of two billion people over the current global tally. Researchers, who published their latest findings in Nature, believe that seafood has the potential to feed the growing world over the next 30 years sustainably – if certain conditions are applied.

Seafood Could Account for 25% of Animal Protein Needed to Meet Increase in Demand in Coming Years

August 24, 2020 — Policy reforms and technological improvements could drive seafood production upward by as much as 75% over the next three decades, research by Oregon State University and an international collaboration suggests.

The findings, published recently in Nature, are important because by 2050 the Earth will have an estimated 9.8 billion human mouths to feed, a 2 billion increase in population from 2020. Seafood has the potential to meet much of the increased need for protein and nutrients, researchers say.
