This article is the latest in a series about computer models and their uses within the Puget Sound ecosystem. As scientists uncover more and more information about a particular ecosystem, computer modelers are often eager to put that raw data to good use in complex models tuned to local conditions. One highly acclaimed model, called […]

New guidance for cleanup of toxics in Puget Sound
An EPA-funded team of scientists and other experts has completed draft recommendations for the future cleanup of toxic chemicals in Puget Sound. The group’s Toxics in Fish Implementation Strategy addresses pollutants such as PCBs and a slew of emerging contaminants that can affect species throughout the waterway. The strategy will be available for public review […]

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 […]

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. […]

Dispatches: Ancient DNA reveals ecological history
Occasionally, this space includes reports and essays from guest writers on the subject of Puget Sound ecosystem recovery. Social scientist Whitney Fleming has this dispatch on new findings that are being revealed by ancient sources. Archaeologists are looking at ancient DNA combined with oral histories to determine ecological conditions from the past. By Whitney Fleming […]

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 […]

Stormwater mimics oil spill’s effect on Pacific herring
Pacific herring exposed to stormwater in Puget Sound show some of the same effects as fish exposed to major oil spills. Symptoms include heart and developmental problems. Read the story from Katie Keil in our magazine Salish Sea Currents.

New Puget Sound herring research
Herring may not be the most charismatic species in Puget Sound. They don’t breach dramatically out of the water. Fish mongers don’t throw them through the air at Pike Place Market. They find their strength in numbers, schooling around by the thousands and serving as food for other creatures like seabirds, salmon and seals. But […]
