• Description:
  In this comprehensive analysis we use the FRAM-Shelton methodology to characterize within-year changes to Chinook salmon prey for SRKW by estimating a) Chinook salmon annual abundance and b) Chinook salmon annual reductions by salmon fisheries in five spatial regions throughout the SRKW migratory range: the Salish Sea, Southwest/West Coast Vancouver Island (SWWCVI), the Washington/Oregon Coast north of Cape Falcon (NOF), the Oregon Coast south of Cape Falcon, and the northern California Coast.
