The Pacific herring, Clupea pallasii, is a species of the herring family associated with the Pacific Ocean environment of North America and northeast Asia. It is a silvery fish with unspined fins and a deeply forked caudal fin. The distribution is widely along the California coast from Baja California north to Puget Sound, Alaska and the Bering Sea.

A 2018 report published by the University of Washington Puget Sound Institute and the Washington Department of Fish and Wildlife brings together an assessment of key science and other knowledge related to herring recovery in the Salish Sea. The report was produced with support from the SeaDoc Society and received input from a cross-border team from state and federal agencies, universities and area tribes.
Last summer, scientists met at the University of Washington to address alarming findings concerning the rapid acidification of the world's oceans. Experts at that symposium warned that wildlife in the Salish Sea, from salmon to shellfish, may start to see significant effects from changing water chemistry within the next 10 to 20 years. This article summarizes the symposium's key findings and was commissioned and edited by the Washington Ocean Acidification Center which hosted the gathering. Funds for the article were provided by the Washington state legislature. [A version of this article was originally published by the Washington Ocean Acidification Center.]
A new report from the Puget Sound Ecosystem Monitoring Program says climate change altered the base of Puget Sound's food web in 2018, diminishing microscopic phytoplankton necessary for marine life. Scientists also observed lower abundances of fish, seabirds, and marine mammals.
Scientists believe that herring have been a staple of Salish Sea food and culture since humans first arrived here at least 12,500 years ago. That importance has continued into modern times, even as herring numbers have declined in parts of the region.
Each winter and spring, researchers survey the sometimes spectacular spawning events of Puget Sound's Pacific herring. They have found wide swings in the fish's population and an overall decline in herring numbers since the 1970s, but little is known about the cause or what this might mean for the health of the food web. We spent a day with a biologist spotting herring eggs and considering the future of one of our region's most ecologically and culturally important fish species.
New research shows that warmer and more acidic oceans could lead to shorter embryos and higher respiration in Pacific herring.
Scientists argue that herring managers should take a tip from stock market investors and diversify the population’s “portfolio.”
Researchers are analyzing the harmful effects of creosote-treated wood pilings on Pacific herring and shellfish in Puget Sound. Studies show that piling removal projects can ease the impacts, but only if carefully done.
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.
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.
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.
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.
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.
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.
In 1996 the Washington State Legislature decided that, in order to effectively target protection efforts in the future, it was time to evaluate how well current efforts to protect Puget Sound are working.
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.
Foraging differences between male and female harbor seals present challenges for fisheries management
A 2015 article published in the Marine Ecology Progress Series identifies intraspecific differences in diet between harbor seals in the Salish Sea, suggesting implications for marine reserve management.
Puget Sound herring reproduction is not limited by the amount of suitable spawning vegetation, according to a November 2014 paper in the journal Marine Ecology. The article points to terrestrial or marine variables as likely determinants of egg loss.
Why did all the grebes leave? Where did they go? And what does their disappearance say about the health of the Salish Sea? Seasonal declines among some regional bird species could hold important clues to the overall health of the ecosystem.
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. Download the panel's summary and proposed research plan.
Download presentations from the Study Panel on Ecosystem-based Management of Forage Fish held August 25, 2013 at the University of Washington’s Friday Harbor Lab, San Juan Island.
Could recent declines in Puget Sound herring be linked to decreases in native eelgrass? Biologist Tessa Francis reports on a new study that may provide insight into the health of one of the region's most iconic forage fish.
This is the executive summary from a technical report produced for the Puget Sound Nearshore Partnership on Valued Ecosystem Components (VEC). The entire document is included as a PDF with this summary.
Forage fish 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.
