At sea, individuals typically are subject to sea lice infestation, which can have detrimental effects on their host. Over recent decades, the body condition and marine survival in <jats:styled-content style=\"fixed-case\">NE<\/jats:styled-content> Atlantic stocks have generally decreased, reflected in fewer adults returning to rivers, which is partly attributable to sea lice. We developed a deterministic stage\u2010structured population model to assess condition\u2010mediated population dynamics resulting in changing fecundity, age at sexual maturation and marine survival rate. The model is parameterized using data from the North Esk system, north\u2010east Scotland. Both constant and density\u2010dependent juvenile survival rates are considered. We show that even small sea lice\u2010mediated changes in mean body condition of <jats:styled-content style=\"fixed-case\">MSW<\/jats:styled-content> can cause substantial population declines, whereas 1<jats:styled-content style=\"fixed-case\">SW<\/jats:styled-content> condition is less influential. Density dependence alleviates the condition\u2010mediated population effect. The resilience of the population to demographic perturbations declines as adult condition is reduced. Indirect demographic changes in salmonid life\u2010history traits (e.g., body condition) are often considered unimportant for population trajectory. The model shows that Atlantic salmon population dynamics can be highly responsive to sea lice\u2010mediated effects on adult body condition, thus highlighting the importance of non\u2010lethal parasitic long\u2010term effects.<\/jats:p>","DOI":"10.1111\/jfd.12748","type":"journal-article","created":{"date-parts":[[2017,11,21]],"date-time":"2017-11-21T06:19:20Z","timestamp":1511245160000},"page":"941-951","source":"Crossref","is-referenced-by-count":15,"title":["Influence of body condition on the population dynamics of Atlantic salmon with consideration of the potential impact of sea lice"],"prefix":"10.1111","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0796-3817","authenticated-orcid":false,"given":"R","family":"Susdorf","sequence":"first","affiliation":[{"name":"Institute of Biological and Environmental Sciences University of Aberdeen Aberdeen UK"},{"name":"Marine Laboratory Marine Scotland Science Aberdeen UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5919-1847","authenticated-orcid":false,"given":"N K G","family":"Salama","sequence":"additional","affiliation":[{"name":"Marine Laboratory Marine Scotland Science Aberdeen UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D","family":"Lusseau","sequence":"additional","affiliation":[{"name":"Institute of Biological and Environmental Sciences University of Aberdeen Aberdeen UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,11,21]]},"reference":[{"unstructured":"Anon(2015).The application of conservation limits for Atlantic Salmon in Scotland.
