In the years 2004\u201306, salmon lice numbers were recorded in selected salmon farms in the fjord as part of a larger research project. Most farm sites participated in a strategic control programme and were deloused between November and January in each year. The aim of the programme was to achieve a mean abundance of &lt;0.3 adult female lice at this time and to minimize the infection pressure on wild smolts in the spring. Dedicated teams carried out detailed counting of lice on farmed fish in April\u2013September each year. Temperature conditions were fairly similar throughout the fjord and amongst years, but wide variations in salinities were observed. The two innermost zones, B and C, had the lowest lice mean abundances, whereas the outermost zones, D and E, consistently had more lice. General linear model analyses showed that differences in adult female lice abundance between the zones were associated with differing levels of salinity and emamectin benzoate treatments strategically administered. Mean fish weight was significantly positively correlated with mean abundance of adult female lice.<\/jats:p>","DOI":"10.1111\/j.1365-2761.2008.01002.x","type":"journal-article","created":{"date-parts":[[2009,2,18]],"date-time":"2009-02-18T14:01:29Z","timestamp":1234965689000},"page":"89-100","source":"Crossref","is-referenced-by-count":31,"title":["Temporal
