A statistical model of the data is developed. In the model, the sea\u2010lice infection is represented by the chalimus (or mobile) lice developing into adult lice and is used to simulate past and current levels of adult lice\u2014including treatments\u2014as well as to predict the adult sea lice level 1\u20132\u00a0months into the future. Time series of the chalimus and adult lice show cross\u2010correlations that shift in time and grow in size with temperature. This implies in\u00a0situ the temperature\u2010dependent development times of about 56 down to 42\u00a0days and the inverted development times (growth rates) of 0.018 up to 0.024\u00a0lice\/day at 8\u201310\u00b0C.

The observed development times at four sites for a year (2010\u201311) were 49, 50, 51 and 52\u00a0days, respectively. Finally, we estimate the sea lice production from fish farms to discuss approaches to control the sea lice epidemics\u2014preferably by natural means. This study is useful for understanding sea lice levels and treatments, and for in\u00a0situ analysis of the sea\u2010lice development times and growth rates.<\/jats:p>","DOI":"10.1111\/jfd.12742","type":"journal-article","created":{"date-parts":[[2017,11,17]],"date-time":"2017-11-17T11:42:37Z","timestamp":1510918957000},"page":"973-993","source":"Crossref","is-referenced-by-count":9,"title":["Statistical modelling of sea lice count data from salmon farms in the Faroe Islands"],"prefix":"10.1111","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0649-7559","authenticated-orcid":false,"given":"H","family":"Gislason","sequence":"first","affiliation":[{"name":"Faculty of Science and Technology, University of the Faroe Islands, N\u00f3at\u00fan 3, FO\u2010100 T\u00f3rshavn, Faroe Islands &amp; Fiskaaling \u2010 Aquaculture Research Station of the Faroes Vi\u00f0 \u00c1ir 11 FO\u2010430 Hvalv\u00edk Faroe Islands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,11,17]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0064039"},{"key":"e_1_2_6_3_1","first-page":"1","volume-title":"Rapport fra Havforskningen","author":"Dalvin S.","year":"2016"},{"key":"e_1_2_6_4_1","volume-title":"Probability and statistics","author":"Degroot M.
