(October photo of salmon in Longfellow Creek by Manuel Valdes)Puget Soundkeeper has released its full report on the fall salmon season in Longfellow Creek. As its announcement explains:For years, Longfellow Creek has been the epicenter of research studying the effects of 6PPD-quinone – a toxic tire chemical lethal to Coho salmon. Puget Soundkeeper’s annual Pre-Spawn Mortality Survey analyzes the spawning success of Coho salmon in Longfellow Creek to better understand the impacts of 6PPD-quinone. Puget Soundkeeper says:Fortunately, solutions exist. Puget Soundkeeper thanks all volunteers, partners, and donors who make this project possible.
