Historical ecology and data-limited fisheries stock assessment methods shed light on threatened Puget Sound Yelloweye Rockfish
By applying elements of historical ecology, fisheries science, and conservation biology in a highly collaborative research effort, researchers from the University of Washington School of Aquatic and Fishery Sciences (SAFS), NOAA Fisheries, and the Washington Department of Fish and Wildlife (WDFW) are delivering new insights into the status of Yelloweye Rockfish. 

New study uses integrated population models to predict extinction risk for Cook Inlet beluga whales and lend insight into factors limiting the recovery of protected populations.
Sparse monitoring data and persistent knowledge gaps can hamper conservation efforts aimed at recovering depleted wildlife populations. In a new study, researchers from the UW School of Aquatic and Fishery Sciences (SAFS) set out to tackle this issue for federally endangered Cook Inlet beluga whales by developing an integrated population model that capitalizes on all available information to understand factors that may be affecting survival, reproduction, and population viability. 

New research led by the University of Washington uses data collected by coastal residents along beaches from central California to Alaska to understand how seabirds have fared in recent decades. The paper, published July 6 in the journal Marine Ecology Progress Series, shows that persistent marine heat waves lead to massive seabird die-offs months later. 

Jason Toft from the UW Wetland Ecosystem Team has been monitoring shoreline armor restoration in Puget Sound for over a decade at sites where artificial armor on beaches has been removed to facilitate the restoration of intertidal areas.
Shoreline armor, also known as seawalls and bulkheads, occurs on over 25% of Puget Sound’s shorelines and was historically installed along homes and infrastructure to address erosion risk. 

A new study produced by The Nature Conservancy (TNC) and the University of Washington (UW), with the lead researcher from SAFS, provides the first-ever nationwide assessment of non-federally managed fisheries in the United States. 

Since 1991, students and faculty at UW’s School of Aquatic and Fishery Sciences have conducted bottom trawl surveys in Port Madison through the School’s Fisheries Ecology course, creating an experiential learning opportunity for students and collecting valuable long-term data on physical and ecological change at a subtidal site in Puget Sound. Fortuitously, this long-term sampling gave students the data needed to investigate an unprecedented mass mortality event.  

In the Arctic, where temperatures are rising at nearly four times the global average, a collaborative effort, combining Indigenous Knowledge with multidisciplinary science has been used to investigate the denning habitat selection of Alaska’s ringed seals.
During the Ikaaġvik Sikukun (Iñupiaq for “Ice Bridges”) project, researchers from the University of Washington School of Aquatic and Fishery Sciences (SAFS), Lamont-Doherty Earth Observatory of Columbia University, University of Alaska Fairbanks, the Native Village of Kotzebue, NOAA, and Farthest North Films collaborated with an Elder Advisory Council of Iñupiaq Qikiqtaġruŋmiut Elders with extensive personal history of subsistence hunting and experience on sea ice. 

Along the seawall, which was designed with the help of UW scientists and engineers and serves as the foundation for the city’s new waterfront, the researchers count herring, shiner perch, sand lance, a growing host of invertebrates and, most importantly, salmon. All kinds of salmon.
This is just one place where the UW’s expertise touches on Seattle’s new central waterfront project, an $835 million public-private effort to reconnect the city’s downtown with Puget Sound. 

Few people would consider launching a boat into Seattle’s Elliott Bay on a winter morning. It’s cold, dark, and more often than not, wet. But the steadfast members of Seattle’s Tengu Club, a Japanese American fishing club that held its first annual salmon derby in 1946, can reliably be found doing just that.
When he first read about the Tengu Derby in the Seattle Times over a decade ago, UW School of Aquatic and Fishery Sciences (SAFS) Professor Thomas Quinn’s interest was piqued. 

Coral reefs can adapt to climate change if given the chance to evolve, according to a study led by Coral Reef Alliance, Rutgers University, the University of Washington and other institutions.
The recent study, published in the journal Nature Ecology and Evolution, finds that coral reefs can evolve and adapt to the effects of climate change—but only if we protect a sufficient diversity of coral reefs, particularly when it comes to temperatures.
