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 Salish Sea Currents.
We’ve published part 2 of Christopher Dunagan’s series on the Salish Sea Marine Survival Project. Getting bigger faster can help save juvenile Chinook salmon from a gauntlet of hungry predators ranging from birds and marine mammals to larger fish. We take a look at what helps salmon grow and prepare for life in the open ocean. Read the story in Salish Sea Currents.
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 Dunagan begins a four-part series on the Salish Sea Marine Survival Project, including new findings presented at the 2018 Salish Sea Ecosystem Conference last spring in Seattle. Read part one of the series in Salish Sea […]
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 put the potential impacts to rest. Eric Wagner reports for our magazine Salish Sea Currents.
Stormwater may be Puget Sound’s most well-known pollutant, and at the same time its least known. While the state has called stormwater Puget Sound’s largest source of toxic contaminants, scientists are still having a tough time answering two basic questions about it: What is stormwater, exactly, and what does it do? Our magazine Salish Sea Currents looks at efforts by researchers to identify toxic chemicals in stormwater that may be killing large numbers of coho salmon in Puget Sound.
By Jeff Rice, Puget Sound Institute The Puget Sound Partnership Salmon Recovery Council has posted a list of recommended priority actions for Chinook salmon recovery. The measures were proposed last spring by area tribes hoping to see stronger efforts to protect the region’s threatened Chinook populations. The document summarizes nine recommendations approved by the Council at its September 28th meeting, including broad language on habitat protection, water quality, water quantity and management of predation of salmon by seals and sea lions. The actions are meant to inform state and federal […]
This much we know: Stormwater is nasty stuff. The state of Washington has called it one of the leading threats to the Puget Sound ecosystem — it can kill salmon within hours and it contributes to all kinds of health problems for species ranging from orcas to humans. What we don’t know is exactly what’s in it. Rain and snowmelt wash an untold number of toxics into our waterways, but there is no such thing as typical stormwater. Its chemical makeup varies from place to place and depends on local […]
This much we know: Stormwater is nasty stuff. The state of Washington has called it one of the leading threats to the Puget Sound ecosystem. It can kill salmon within hours and it contributes to all kinds of health problems for species ranging from orcas to humans. What we don’t know, however, is exactly what’s in it. Rain and snowmelt wash an untold number of toxic chemicals from our streets and other impervious surfaces directly into our waterways, but there is no such thing as typical stormwater. It simply includes […]
In recent decades, hundreds of millions of dollars have been spent to restore habitat for Puget Sound salmon. This month, PSI senior writer Christopher Dunagan looks at how scientists are gauging their progress. Are environmental conditions improving or getting worse? The answer may depend on where you look and who you ask. Read the article in Salish Sea Currents.
The Puget Sound Salmon Recovery Council wants the opportunity to clarify the meaning of a new tribal proposal. By Christopher Dunagan, Puget Sound Institute Native American tribes in the Puget Sound region are calling for “bold actions” to reverse the decline of Puget Sound Chinook salmon, listed as threatened under the Endangered Species Act. Such actions would include: — Protecting all remaining salmon habitat in and around Puget Sound with more consistent and enforceable land-use regulations; — Preventing water uses that would limit salmon recovery; — Improving management of predators, […]
Scientists know this much about stormwater: It can be extremely toxic. It can kill exposed fish such as coho salmon within hours. But figuring out exactly what is in stormwater has been a complex puzzle that has so far confounded scientists. Many of the chemical compounds in it remain unidentified. Is there such a thing as typical stormwater, or is it so variable that patterns can’t be detected? That has been the subject of research by Center for Urban Waters research scientist and PSI collaborator Ed Kolodziej, who will be presenting some […]
This week in Salish Sea Currents: PSI senior writer Christopher Dunagan reports on a new approach to flood control in Puget Sound. Rivers, scientists say, can be contained by setting them free. Conservationists hope this is good news for salmon recovery. The story is part of our ongoing series on the science of Puget Sound recovery.
