SPECIES 5: The Salish Sea Marine Survival Project: Juvenile salmonid growth and survival
Over the past 30‐40 years, marine survival of Chinook, coho, and steelhead populations in the Salish Sea has declined precipitously, and total abundance today remains well below 1970s‐1980s abundances. Historically, our understanding of what drives salmon and steelhead survival in saltwater has been limited. In response to this need, Long Live the Kings (U.S.) and the Pacific Salmon Foundation (Canada) developed a comprehensive transboundary approach to determine the primary factors affecting salmon and steelhead survival in the Salish Sea.
The Salish Sea Marine Survival Project (SSMSP; www.marinesurvivalproject.org) brings together multidisciplinary international expertise from over 60 U.S. and Canadian agencies, Tribes and First Nations, academia, and non-profit organizations. The project’s integrated, ecosystem‐based research framework incorporates coordinated data collection and standardization, information sharing, and international collaboration to better understand population dynamics within the Salish Sea ecosystem, improve forecasting and management, and aid recovery. The research phase of the Project is 2014‐2018; it culminates with a focus on converting research results into conclusions and management actions.
The presentations in this session explored the impacts of prey availability, prey quality, habitat use, and ocean conditions on juvenile salmon growth and survival in the northern Salish Sea. Results suggested that juvenile salmon in the Strait of Georgia occupy a broad range of habitats and exhibit individualized behavior with regards to habitat use. Localized prey production and ocean conditions may impact juvenile salmon health and survival, and growth during the juvenile phase is positively related to survival to adulthood for some stocks.
