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. Introduction Social science and equity are increasingly considered integral aspects …

New studies on emerging threats to salmon

Chemicals, disease and other stressors can increase a salmon’s chance of being eaten or reduce its ability to catch food. We wrap up our series on the Salish Sea Marine Survival Project with a look at some of the lesser-known, but still significant factors contributing to salmon declines in the Salish Sea. Read the story in …

Removal of creosote-treated pilings may assist herring recovery

Thousands of abandoned wood pilings — the ghosts of piers and docks past — are located throughout Puget Sound. Most of them are treated with creosote, a toxic chemical used to preserve wood that contains polycyclic aromatic hydrocarbons (PAHs), a class of chemicals that are also associated with oil spills and burning of fossil fuels. …

Could anchovies and other fish take pressure off salmon and steelhead?

A recent influx of anchovies into Puget Sound may have saved some steelhead from predators, but researchers seek more evidence to prove the connection. Our series on the Salish Sea Marine Survival Project continues with a look at these and other potential impacts from predators on the region’s salmon and steelhead. Read the story in …

Opening the black box: What’s killing Puget Sound’s salmon and steelhead?

An intensive research program in the U.S. and Canada is studying why so few salmon in the Salish Sea are returning home to spawn. They are uncovering a complex web of problems involving predators, prey and other factors that put salmon at risk as they migrate to the ocean. Puget Sound Institute senior writer Christopher …

Despite WA ban on farmed salmon, BC impacts may flow across border

A high-profile salmon escape led to a ban on salmon farms in Washington earlier this year. But just across the border, scientists say salmon farms in British Columbia expose migrating fish from Puget Sound to potential maladies like parasites, bacteria and dangerous viruses. They say simply getting rid of salmon farms in Washington does not …

Ocean acidification may be twice as extreme in Puget Sound’s seagrass habitats, threatening Dungeness crabs

Ocean acidification could be up to twice as severe in fragile seagrass habitats as it is in the open ocean, according to a study published last month in the Proceedings of the National Academy of Sciences. The conditions may threaten Dungeness crabs by 2050 and will be especially pronounced in the winter, the study says. …

Diving deeper to understand eelgrass wasting disease

New studies show that eelgrass wasting disease is more common in warmer waters, leading to concerns over the future effects of climate change on eelgrass populations in Puget Sound. We continue our series on science findings from the 2018 Salish Sea Ecosystem Conference. Robin McLachlan reports for Salish Sea Currents.

Bay mussels in Puget Sound show traces of oxycodone

By Jeff Rice The opioid epidemic has now hit the waters of Puget Sound. State agencies tracking pollution levels in Puget Sound have discovered traces of oxycodone in the tissues of native bay mussels (Mytilus trossulus) from Seattle and Bremerton area harbors. The mussels were part of the state’s Puget Sound Mussel Monitoring Program. Every …
