Forage fish (or forage fishes) are small schooling fish that form a critical link in the marine food web between zooplankton and larger fish and wildlife consumers. They occupy every marine and estuarine nearshore habitat in Washington, and much of the intertidal and shallow subtidal areas of the Puget Sound Basin are used by these species for spawning habitat. Status of forage fish populations can be an indicator of the health and productivity of nearshore systems (PSP 2009). Information on forage fish life history, distribution, and habitat preferences is summarized in Marine Forage Fishes of Puget Sound (Penttila 2007) and the Forage Fish Management Plan (Bargmann 1998).

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.
The Puget Sound Ecosystem Monitoring Program has released its sixth annual Marine Waters Overview. The report provides an assessment of marine conditions for the year 2016 and includes updates on water quality as well as status reports for select plankton, seabirds and fish.
A new study shows a surprising decline in some toxic chemicals in Puget Sound fish, while levels of PCBs increased in some cases. Scientists say the study shows that banning toxic chemicals can work, but old contaminants remain a challenge as they continue to wash into Puget Sound.
A 2017 report from the Puget Sound Ecosystem Monitoring Program presents an overview of selected recent monitoring and research activities focused on toxic contaminants in the Salish Sea.
The Puget Sound Ecosystem Monitoring Program (PSEMP) is an independent program established by state and federal statute to monitor environmental conditions in Puget Sound.
A 2016 article in the journal Conservation Letters makes policy recommendations to address shoreline armoring in the Salish Sea.
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.
Sand lance in parts of British Columbia are ingesting small pieces of plastic that may be passed through the food web.
Some of the most important fish in the Salish Sea food web are also the most mysterious. Researchers have only begun to understand how many there are, where they go, and how we can preserve their populations for the future. A University of Washington researcher describes how scientists are looking into the problem.
Researchers are proposing a shift in thinking about how some of the region’s most damaging pollutants enter Puget Sound species like herring, salmon and orcas.
Where shoreline bulkheads remain in place, the loss of spawning habitat used by surf smelt is likely to reach 80 percent.
Rising sea levels are expected to exacerbate habitat loss caused by bulkheads, according to studies in the San Juan Islands.
A 2016 paper in the journal Oecologia describes how individual herring populations in Puget Sound exhibit a portfolio effect, collectively influencing and stabilizing the region’s population as a whole.
Food webs are natural interconnections of food chains and depict what-eats-what in an ecological community. While Puget Sound represents a specific food web, the organisms that reside within that web often travel outside the region. In this way, one community's food web can be drastically affected by a change in a neighboring ecosystem.
The health of an ecosystem is tied closely to the health of its food webs. This article provides an overview of the concept, origin, and characteristics of a food web and how predator and prey relationships are shaped in the Salish Sea.
Pacific herring have long been considered an essential part of the Puget Sound food web. Now, studies are beginning to reveal how diseases in herring could be reverberating through the ecosystem, affecting creatures large and small. We continue our coverage of the ecological impacts of disease in Puget Sound with this look at the region's most well-known forage fish.
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 2015 NOAA report creates an updated and comprehensive list of the fishes of the Salish Sea.
Conservation and ecology of marine forage fishes— Proceedings of a research symposium, September 2012
The symposium was held on September 12–14, 2012, at the University of Washington, Friday Harbor Laboratories campus. Sixty scientists, graduate students, and fisheries policy experts convened; showcasing ongoing research, conservation, and management efforts targeting forage fish from regional and national perspectives.
This is the Puget Sound Water Quality Action Team's third report on key indicators of Puget Sound's Health. We prepared the report in response to the Washington State Legislature's request to evaluate efforts to protect Puget Sound. The report includes updated information on the 17 indicators presented in 2000 as well as information on two new indicators.
Forty years of change in forage fish and jellyfish abundance across greater Puget Sound, Washington (USA): anthropogenic and climate associations
A 2015 paper in the Marine Ecology Press Series reports a trend toward more jellyfish and less of some forage fish species in Puget Sound. The paper analyzes more than 40 years of state data, and assesses potential human causes for the shift.
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.
Forage fish represent a critical link in the Puget Sound food web and help to sustain key species like salmon, marine mammals and sea birds. But the region’s forage fish may be vulnerable on a variety of fronts, according to a new study panel report from the University of Washington Puget Sound Institute.
