PSI’s Andy James is collaborating with scientists at NOAA and Washington State University to understand how wastewater affects juvenile salmon in Puget Sound. The study is led by Jim Meador of NOAA’s Northwest Fisheries Sciences Center and focuses on discharge from three major sewage treatment plants in King County. Wastewater will be analyzed at the […]

Ancient harvests: A history of Salish Sea herring
If you were to ask a group of experts to make a list of culturally important foods in the Pacific Northwest, it would not be a surprise if salmon rose to the top. But researchers say Pacific herring may have at times rivaled salmon in importance in the Salish Sea. Scientists believe that herring have […]

The herring defenders
Herring numbers have been declining in Puget Sound since surveys for them began in the 1970s, but it is unclear what is causing those declines, even in the face of widespread fisheries closures. Less clear still is whether anything else can be done to stop or reverse them, and bring herring back. Our reporter Eric […]

Video: Identifying sources of pollution in the Skagit Valley
A video produced by the University of Washington Center for Urban Waters shows how chemical tracers can identify sources of pollution affecting shellfish growers in Puget Sound’s Skagit Valley. Fecal coliform pollution is a widespread problem in Puget Sound, resulting in costly beach and shellfish bed closures whenever it is detected. Analytical techniques can now […]

Test your herring knowledge
By Jeff Rice One of the first steps in protecting any species is understanding as much as you can about it. When it comes to Pacific herring in the Salish Sea, much is known but until recently many of the key scientific findings about the species had not been gathered together in a single place. […]

Equity and social science integration at the 2018 Salish Sea Ecosystem Conference
A new study looks at social science and equity integration within the proceedings of the 2018 Salish Sea Ecosystem Conference. The study was produced by David Trimbach on behalf of the Puget Sound Partnership for the Encyclopedia of Puget Sound and the Puget Sound Institute. From the report’s Introduction: Social science and equity are increasingly […]

How herring learn from their elders
Young Pacific herring (Clupea pallasii) learn migration behavior by joining up with older fish, according to a new paper co-authored by Puget Sound Institute Lead Ecosystem Ecologist Tessa Francis. The paper, published this month in the ICES Journal of Marine Science, showed how this behavior leads to greater spatial variability in biomass, and that commercial […]
