The term shellfish refers to edible aquative invertebrates that have exoskeletons, or shells. Species in Puget Sound range from Dungeness crabs and oysters to shrimp and squid.
After a long struggle with pollution, Drayton Harbor has reopened to year-round commercial oyster harvesting for the first time in 22 years. Here’s how the community cleaned up its act, potentially showing the way for shellfish recovery throughout Puget Sound.
Scientists are testing ways to use transplanted shellfish such as mussels to monitor toxic contaminants in Puget Sound.
Invasive species are considered a top threat to the balance of ecosystems worldwide. New discoveries of non-native green crabs in Puget Sound have highlighted that concern here at home, but invasive species can impact more than just the food web. Some introduced species can produce toxins that accumulate in shellfish or by directly infecting the human body.
The Puget Sound Ecosystem Monitoring Program released its fifth annual Marine Waters Overview this week. The report provides an assessment of marine conditions for the year 2015 and includes updates on water quality as well as status reports for select plankton, seabirds, fish and marine mammals.
Another European green crab has been spotted in Puget Sound prompting concern that the species may gain a foothold in the region.
Concerns over the potential arrival of the European green crab have inspired a small army of volunteers. A search is underway for early signs of an invasion.
A July 2016 report from the University of Washington Puget Sound Institute summarizes and reviews 10 EPA-funded projects focusing on Puget Sound's marine and nearshore environments. The projects were conducted between 2011-2015 with support from the EPA's National Estuary Program. The report is an analysis of findings on invasive species, toxics, oil spill, and integrated risk assessment.
Environmental samplers may provide early detection of harmful algal blooms (HABs) in Puget Sound. This toxic algae is expected to increase as the climate changes, bringing with it new and potentially more severe outbreaks of shellfish poisonings.
An algal bloom is a rapid increase or accumulation in the population of algae in a water system. While most are innocuous, there are a small number of algae species that produce harmful toxins to humans and animals.
A 2015 report from the Whatcom Conservation District and Whatcom County describes a pilot watershed characterization study focusing on the Terrell Creek and Birch Bay areas. The report and related appendices are available for download.
The 2015 Puget Sound Fact Book brings together statistics and other information about the health and makeup of the Puget Sound ecosystem. Areas of focus include climate change, geography, water quality, habitats, human dimensions and regional species. The fact book was prepared for the Encyclopedia of Puget Sound with funding from the Environmental Protection Agency and the Puget Sound Partnership.
A report from NOAA and the Puget Sound Ecosystem Monitoring Program provides an overview of 2014 marine water quality and conditions in Puget Sound from comprehensive monitoring and observing programs.
The Puget Sound Water Quality Conference was held in Seattle, Washington, on September 30 and October 1, 1983. It included prominent speakers from the Puget Sound region, other parts of the United States, and Canada.
Review of the marine environment and biota of Strait of Georgia, Puget Sound and Juan de Fuca Strait
Proceedings of the BC/Washington Symposium on the Marine Environment, January 13 and 14, 1994
This is the first State of the Sound Report. It summarizes much of what is known about the Puget Sound basin—its history, economy, human population, land uses and other factors influencing its water quality.
The 1993 Puget Sound Update—the fourth annual report of this program—evaluates the data collected by PSAMP in 1992 (the most recent year for which the data have undergone quality assurance review and interpretation) and compares these data to past information on Puget Sound water quality.
The 1994 Puget Sound Update—the fifth annual summary report of this program—evaluates the data collected by the PSAMP in 1993 (the most recent year for which the data have undergone quality assurance review and interpretation) and compares these data to past information on Puget Sound.
A 2005 report from the Washington Sea Grant Program describing the history and current state of native Olympia oysters including their ecology, history with human interactions, prefered habitat, and reestablishment efforts in the Puget Sound region.
The shellfish industry is a cornerstone of the Puget Sound economy, but the region's famed mollusks provide more than just money and jobs. They offer what are called ecosystem services—a wide variety of benefits that humans derive from an ecosystem.
This 2006 technical report for the Puget Sound Nearshore Partnership describes how shellfish have high ecological, economical, cultural, recreational value, however human activity is threatening their existence by altering their native habitat with changes in land use, shoreline modifications, stormwater, sewage and industrial discharge.
Northwest Coast First Peoples made clam garden terraces to expand ideal clam habitat at tidal heights that provided optimal conditions for clam growth and survival, therefore enhancing food production and increasing food security.
A report from the Puget Sound Ecosystem Monitoring Program provides an overview of 2013 marine water quality and conditions in Puget Sound from comprehensive monitoring and observing programs.
Scientists say eelgrass, an unassuming flowering plant found just off shore in Puget Sound, is vital to the health of the ecosystem. They also say the plant is declining. New and increasingly urgent efforts to restore it brought a group of researchers to the 2014 Salish Sea Ecosystem Conference.
Several research groups in the region are investigating biological markers and/or impacts of Contaminant of Emerging Concern (CEC) exposure in different organisms. An abstract describing each study is included below. Also included are links or contact details for further information about each project.
A November 2013 literature review by Washingtom Sea Grant synthesizes the state of the science of geoduck clams and the potential environmental impacts of geoduck aquaculture in the Puget Sound region.
The Puget Sound Marine Waters 2012 Overview from the Puget Sound Ecosystem Monitoring Program synthesizes conditions measured in 2012 and has been expanded to include observations on seabirds that rely on marine waters. Read an excerpt below, or download the full report.
Dungeness crabs are an important resource in Puget Sound for recreational, commercial, and tribal fisheries. They utilize a variety of habitats over the course of their lives, and are vulnerable to shifts in ocean temperature and water quality.
Sweetening the waters - the feasibility and efficacy of measures to protect Washington’s marine resources from ocean acidification
Washington State's ocean acidification initiative began with the launch of Governer Christine Gregoire's Blue Ribbon Panel on Ocean Acidification in December 2011. The initiative is the first of its kind in the country, and a report commissioned by the Global Ocean Health Program was released in November 2012. The report is a first step towards assessing and improving the tools at hand.
The Puget Sound Marine Waters 2011 report is now available. The report was produced by the Puget Sound Ecosystem Monitoring Program and assesses the condition and quality of the waters of Puget Sound.
