However, in practice, the post\u2010treatment counting window varies from the day of treatment to several days after treatment. In this study, we assess the effect of post\u2010treatment lag time on sea lice abundance estimates after chemical bath treatment using data from the sea lice data management program (<jats:italic>Fish\u2010iTrends<\/jats:italic>) between 2010 and 2014. Data on two life stages, (i) adult female (AF) and (ii) pre\u2010adult and adult male (PAAM), were aggregated at the cage level and log\u2010transformed. Average sea lice counts by post\u2010treatment lag time were computed for AF and PAAM and compared relative to treatment day, using linear mixed models. There were 720 observations (treatment events) that uniquely matched pre\u2010 and post\u2010treatment counts from 53 farms. Lag time had a significant effect on the estimated sea lice abundance, which was influenced by season and pre\u2010treatment sea lice levels. During summer, sea lice were at a minimum when counted 1\u00a0day post\u2010treatment irrespective of pre\u2010treatment sea lice levels, whereas in the spring and autumn, low levels were observed for PAAM over a longer interval of time, provided the pre\u2010treatment sea lice levels were &gt;5\u201310.<\/jats:p>","DOI":"10.1111\/jfd.12519","type":"journal-article","created":{"date-parts":[[2016,8,15]],"date-time":"2016-08-15T10:22:40Z","timestamp":1471256560000},"page":"367-375","source":"Crossref","is-referenced-by-count":11,"title":["Effect of timing of count events on estimates of sea lice abundance and interpretation of effectiveness following bath treatments"],"prefix":"10.1111","volume":"40","author":[{"given":"R","family":"Gautam","sequence":"first","affiliation":[{"name":"Department of Health Management and Centre for Veterinary Epidemiology Research Atlantic Veterinary College University of Prince Edward Island Charlottetown PE Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R","family":"Vanderstichel","sequence":"additional","affiliation":[{"name":"Department of Health Management and Centre for Veterinary Epidemiology Research Atlantic Veterinary College University of Prince Edward Island Charlottetown PE Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A S","family":"Boerlage","sequence":"additional","affiliation":[{"name":"Department of Health Management and Centre for Veterinary Epidemiology Research Atlantic Veterinary College University of Prince Edward Island Charlottetown PE Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C W","family":"Revie","sequence":"additional","affiliation":[{"name":"Department of Health Management and Centre for Veterinary Epidemiology Research Atlantic Veterinary College University of Prince Edward Island Charlottetown PE Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K L","family":"Hammell","sequence":"additional","affiliation":[{"name":"Department of Health Management and Centre for Veterinary Epidemiology Research Atlantic Veterinary College University of Prince Edward Island Charlottetown PE Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,8,15]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"34","article-title":"Water movement and fish health in the salmon farming industry of southwestern New Brunswick","volume":"105","author":"Beattie M.J.","year":"2005","journal-title":"Bulletin of the Aquaculture Association of Canada"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.icesjms.2006.04.017"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1163\/18759866-0690102005"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.3354\/dao051101"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aquaculture.2014.05.018"},{"key":"e_1_2_6_7_1","unstructured":"CornerR.A.
