Salmon lice epizootics resulting from aquaculture have shifted these trade\u2010offs, as salmon lice might both increase mortality and reduce growth of sea trout. We studied mortality and behavioural adaptations of wild sea trout in a large\u2010scale experiment with acoustic telemetry in an aquaculture intensive area that was fallowed (emptied of fish) synchronically biannually, creating large variations in salmon lice concentrations. We tagged 310 wild sea trout during 3\u00a0years, and gave half of the individuals a prophylaxis against further salmon lice infestation. There was no difference in survival among years or between treatments. In years of high infestation pressure, however, sea trout remained closer to the river outlet, used freshwater (FW) habitats for longer periods and returned earlier to the river than in the low infestation year. This indicates that sea trout adapt their migratory behaviour by actively choosing FW refuges from salmon lice to escape from immediate mortality risk. Nevertheless, simulations show that these adaptations can lead to lost growth opportunities. Reduced growth can increase long\u2010term mortality of sea trout due to prolonged exposure to size\u2010dependent predation risk, lead to lower fecundity and, ultimately, reduce the likelihood of sea migration.<\/jats:p>","DOI":"10.1111\/jfd.12749","type":"journal-article","created":{"date-parts":[[2017,11,21]],"date-time":"2017-11-21T01:16:50Z","timestamp":1511227010000},"page":"953-967","source":"Crossref","is-referenced-by-count":62,"title":["Sea trout adapt their migratory behaviour in response to high salmon lice concentrations"],"prefix":"10.1111","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3540-6276","authenticated-orcid":false,"given":"E","family":"Halttunen","sequence":"first","affiliation":[{"name":"Institute of Marine Research (IMR) Troms\u00f8 Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K\u2010\u00d8","family":"Gjelland","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Nature Research (NINA) Trondheim Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S","family":"Hamel","sequence":"additional","affiliation":[{"name":"Department of Arctic and Marine Biology Faculty of Biosciences, Fisheries and Economics The Arctic University of Norway Troms\u00f8 Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R\u2010M","family":"Serra\u2010Llinares","sequence":"additional","affiliation":[{"name":"Institute of Marine Research (IMR) Troms\u00f8 Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R","family":"Nilsen","sequence":"additional","affiliation":[{"name":"Institute of Marine Research (IMR) Troms\u00f8 Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P","family":"Arechavala\u2010Lopez","sequence":"additional","affiliation":[{"name":"Department of Marine Sciences and Applied Biology University of Alicante Alicante Spain"},{"name":"Department of Ecology of Marine Resources Mediterranean Institute for Advanced Studies Esporles Mallorca Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J","family":"Skar\u00f0hamar","sequence":"additional","affiliation":[{"name":"Institute of Marine Research (IMR) Troms\u00f8 Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I A","family":"Johnsen","sequence":"additional","affiliation":[{"name":"Institute of Marine Research (IMR) Bergen Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L","family":"Asplin","sequence":"additional","affiliation":[{"name":"Institute of Marine Research (IMR) Bergen Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00d8","family":"Karlsen","sequence":"additional","affiliation":[{"name":"Institute of Marine Research (IMR) Bergen Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P\u2010A","family":"Bj\u00f8rn","sequence":"additional","affiliation":[{"name":"Institute of Marine Research (IMR) Troms\u00f8 Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B","family":"Finstad","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Nature Research (NINA) Trondheim Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,11,21]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40071-016-0127-0"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/17451000.2013.810755"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fishres.2012.01.024"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.18637\/jss.v067.i01"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1139\/f96-231"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1023\/A:1007354632039"},{"key":"e_1_2_6_8_1","first-page":"60","article-title":"The physiological effects of salmon lice infection on sea trout post smolts","volume":"73","author":"Bj\u00f8rn P.
