This field study documents the stress effects on Atlantic salmon and the effect on salmon lice dynamics during large-scale use of the AcuLice system. The effect of the AcuLice treatment on salmon lice dynamics was measured by weekly salmon lice counting at the facilities from mid-summer 2019 to late-spring 2020. The number of salmon lice treatments in the same period was also compared to a reference group. In addition, the number of weeks until the first salmon lice treatment (mechanical treatment) was compared between the two groups. Apart from a slight increase in plasma glucose, no significant differences were observed in the primary, secondary, or tertiary stress responses measured. For the mature female salmon lice, a significantly lower number (mean \u00b1 SEM) was shown for the AcuLice group (0.24 \u00b1 0.03) compared to the reference group (0.44 \u00b1 0.04). In addition, a lower number (mean \u00b1 SEM) of salmon lice treatments and a longer production period before the first salmon lice treatment occurred was observed at the AcuLice facilities (33.2 \u00b1 3 weeks) compared to the reference facilities (20.3 \u00b1 2 weeks). These data suggest that the use of the AcuLice system reduces the need for traditional salmon lice treatments with no added stress to the fish.<\/jats:p>","DOI":"10.3390\/jmse10081004","type":"journal-article","created":{"date-parts":[[2022,7,22]],"date-time":"2022-07-22T12:53:45Z","timestamp":1658494425000},"page":"1004","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Acoustic Delicing of Atlantic Salmon (Salmo salar): Fish Welfare and Salmon Lice (Lepeophtheirus salmonis) Dynamics"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3980-4009","authenticated-orcid":false,"given":"Bibbi Maria K\u00e1llay","family":"Hjelle","sequence":"first","affiliation":[{"name":"Department of Biological Sciences, High Technology Centre, University of Bergen, 5020 Bergen, Norway"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0077-8077","authenticated-orcid":false,"given":"Albert Kjartan Dagbjartarson","family":"Imsland","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, High Technology Centre, University of Bergen, 5020 Bergen, Norway"},{"name":"Akvaplan-niva Iceland Office, 201 K\u00f3pavogur, Iceland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9365-6775","authenticated-orcid":false,"given":"Pablo Vigo","family":"Balseiro","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, High Technology Centre, University of Bergen, 5020 Bergen, Norway"}]},{"given":"Sigurd Olav","family":"Handeland","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, High Technology Centre, University of Bergen, 5020 Bergen, Norway"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"188","DOI":"10.1006\/jmsc.1997.0361","article-title":"Host factors important in sea lice infections","volume":"55","author":"Mackinnon","year":"2018","journal-title":"ICES J.
