The eggs and carcasses of semelparous pink salmon may provide a significant nutrient and energy subsidy to native biota, but this phenomenon has not been widely documented outside the species' native distribution. We analysed the stomach contents and stable isotope values (\u03b4<jats:sup>15<\/jats:sup>N and \u03b4<jats:sup>13<\/jats:sup>C) in muscle and liver tissues of juvenile Atlantic salmon (<jats:italic>Salmo salar<\/jats:italic>) and brown trout (<jats:italic>Salmo trutta<\/jats:italic>) to determine whether these native salmonids utilise marine\u2010derived nutrients and energy provided by pink salmon eggs and carcasses in the subarctic river system Vesterelva, northern Norway. Although egg foraging and assimilation of marine\u2010derived nutrients in fish body tissues were found to be minor at the population level, a few juvenile salmon and trout had recently eaten large quantities of pink salmon eggs. Some of these individuals also had high \u03b4<jats:sup>15<\/jats:sup>N and \u03b4<jats:sup>13<\/jats:sup>C values, indicating a long\u2010term diet subsidised by marine\u2010derived nutrients and energy from pink salmon eggs. Hence, our study provides novel evidence that the eggs of invasive pink salmon may provide an energetic, profitable food resource for juvenile native fish. More research is needed to understand the broader ecological implications for fishes and other biota in river ecosystems invaded by pink salmon.<\/jats:p>","DOI":"10.1111\/eff.12582","type":"journal-article","created":{"date-parts":[[2020,11,17]],"date-time":"2020-11-17T07:57:05Z","timestamp":1605599825000},"page":"270-283","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Evidence of energy and nutrient transfer from invasive pink salmon (<i>Oncorhynchus gorbuscha<\/i>) spawners to juvenile Atlantic salmon (<i>Salmo salar<\/i>) and brown trout (<i>Salmo trutta<\/i>) in northern Norway"],"prefix":"10.1111","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2397-1841","authenticated-orcid":false,"given":"Kathy","family":"Dunlop","sequence":"first","affiliation":[{"name":"Institute of Marine Research Troms\u00f8 Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antti P.","family":"Eloranta","sequence":"additional","affiliation":[{"name":"Department of Biological and Environmental Science University of Jyv\u00e4skyl\u00e4 Jyv\u00e4skyl\u00e4 Finland"},{"name":"Norwegian Institute for Nature Research Trondheim Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erik","family":"Schoen","sequence":"additional","affiliation":[{"name":"Institute of Arctic Biology University of Alaska Fairbanks Fairbanks AK USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Wipfli","sequence":"additional","affiliation":[{"name":"U.S. Geological Survey Alaska Cooperative Fish and Wildlife Research Unit Institute of Arctic Biology University of Alaska Fairbanks Fairbanks AK USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jenny L.A.","family":"Jensen","sequence":"additional","affiliation":[{"name":"Akvaplan\u2010niva AS Fram Centre Troms\u00f8 Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rune","family":"Muladal","sequence":"additional","affiliation":[{"name":"Naturtjenester i Nord Troms\u00f8 Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guttorm N.","family":"Christensen","sequence":"additional","affiliation":[{"name":"Akvaplan\u2010niva AS Fram Centre Troms\u00f8 Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,11,16]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1095-8649.1999.tb00612.x"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1095-8649.2000.tb00765.x"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0990-7440(01)01127-5"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/jfb.14151"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1139\/F10-127"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1890\/09-0790.1"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00114-010-0656-0"},{"key":"e_1_2_8_9_1","volume-title":"MuMIn: Multi\u2010model inference","author":"Barton K.","year":"2016"},{"key":"e_1_2_8_10_1","volume-title":"Pukkellaks i Norge, 2019","author":"Berntsen H.
