Abstract Excerpt:
Marine growth and survival of juvenile Pacific salmon (Oncorhynchus spp.) has been linked to marine temperatures and feeding conditions during their first few months at sea (Beauchamp et al. 2007; Farley et al. 2007; Fergusson et al. 2013). Evidence from the Bering Sea (Siddon et al. 2013; Eisner et al. 2017), Prince William Sound (Armstrong et al. 2011; McKinstry and Campbell 2018), and Southeast Alaska (SEAK; Landingham et al. 1998; Sturdevant et al. 2012) suggest that the juvenile salmon prey community is responsive to environmental change, and that these changes are reflected in their species richness, abundance, and nutritional quality. Therefore, understanding what salmon consume under varying environmental conditions is important to understanding how their growth and survival is affected by climate change.
