This study evaluated the fin condition of Salmo salar at different abundances of the parasite Caligus rogercresseyi. Fish were exposed to infestation with copepodids and the cohort was allowed to develop to the adult stage. The relative fin index was measured. Significant differences between infested and control fish for both pectoral and anal fins were observed. Moreover, there were significant negative relationships between fin condition and parasite abundances for pectoral, anal, and pelvic fins, suggesting that infestations with C. rogercresseyi could be a possible cause for fin damage in Atlantic salmon. Moreover, this damage was associated with increased stress levels, suggesting that damage can be related to physiological changes on infested fish. According to these results, pectoral fin assessments have the potential to provide information on the welfare of fish with C. rogercresseyi infestation. Determining the causes of poor fin development may improve fish welfare, even when infested by parasites.<\/jats:p>","DOI":"10.3390\/ani10071166","type":"journal-article","created":{"date-parts":[[2020,7,10]],"date-time":"2020-07-10T09:25:28Z","timestamp":1594373128000},"page":"1166","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Fin Erosion of Salmo salar (Linnaeus 1758) Infested with the Parasite Caligus rogercresseyi (Boxshall &amp; Bravo 2000)"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0382-0736","authenticated-orcid":false,"given":"Margarita P.","family":"Gonz\u00e1lez","sequence":"first","affiliation":[{"name":"Programa de Doctorado en Ciencias de la Acuicultura, Escuela de Graduados, Universidad Austral de Chile, Los Pinos s\/n, Balneario Pelluco, Puerto Montt 5500000, Chile"},{"name":"Departamento de Salud Hidrobiol\u00f3gica, Divisi\u00f3n de Acuicultura, Instituto de Fomento Pesquero, Balmaceda 252, Puerto Montt 5501248, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandra L.","family":"Mar\u00edn","sequence":"additional","affiliation":[{"name":"Instituto de Acuicultura, Universidad Austral de Chile, Los Pinos s\/n, Balneario Pelluco, Puerto Montt 5500000, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Melinka","family":"Mancilla","sequence":"additional","affiliation":[{"name":"Laboratorio de Interacciones Ecol\u00f3gicas (LINTEC), Universidad Austral de Chile, Los Pinos s\/n, Balneario Pelluco, Puerto Montt 5500000, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0624-9563","authenticated-orcid":false,"given":"Hern\u00e1n","family":"Ca\u00f1on-Jones","sequence":"additional","affiliation":[{"name":"Facultad de Medicina Veterinaria y Agronom\u00eda, Universidad de las Am\u00e9ricas, Avda.
