What Chinook salmon eat depends on where they are in the Salish Sea, study finds

A new study by University of Victoria (UVic) and Pacific Salmon Foundation (PSF) scientists has uncovered what adult Chinook salmon in the Salish Sea are eating—and revealed diet can differ according to region. The study, led by UVic Ph.D. student Wesley Greentree and published recently in Fisheries Oceanography, analyzed the contents of salmon stomachs to assess salmon diet. Greentree found that year-round, herring are the most important food for adult Chinook salmon throughout the Salish Sea. Anchovy were often found in stomachs collected near Howe Sound and sand lance were important in Victoria and Sidney.
