The diet of juvenile chinook salmon (Oncorhynchus tshawytscha) in the Strait of Georgia, 2000-2017 / by Chrys-Ellen M. Neville, Lana C. Fitzpatrick and Richard J. Beamish. : Fs97-6/3525E-PDF
"Diets of juvenile Chinook salmon during their first summer and fall in the Strait of Georgia, British Columbia, Canada are summarized for studies from 2000 - 2017. Approximately 21,000 juvenile Chinook salmon were sampled with all analyses conducted by the same expert and most analyses completed on fresh samples during the surveys. Comparison across the 18 years showed that juvenile Chinook salmon had a very consistent diet with four items representing over 90% of all stomach contents. An exception was in 2007 when there was a failure in the year class of Pacific herring. There was a relatively small proportion of empty stomachs in all years and these empty stomachs were observed across size classes"--Abstract, page vi.
