Abstract Excerpt:
Density-dependent effects between pink salmon (Oncorhynchus gorbuscha) and other species, including other species of Pacific salmon, have been documented by a number of studies. Density-dependent interactions between pink and Chinook salmon (O. tshawytscha) have also been previously hypothesized in the Salish Sea (Claiborne et al. in press; Ruggerone and Goetz 2004; Ruggerone et al. 2019), a rich and diverse but highly-impacted inland sea in Washington State and British Columbia. In the central and southern parts of the Salish Sea, almost all pink salmon spawn in odd-numbered years and juveniles emigrate in even-numbered years. Juvenile Chinook and pink salmon are both found there between April through July of even years (Duffy et al. 2005; B. Berejikian, NOAA Fisheries, unpublished data).
