Parasite assessments are therefore critical to keep track of infections. If conventional sampling techniques can be simplified, parasite assessments might be easier to obtain, less time\u2010consuming and more extensive. In this study, we compare the assessed number of <jats:italic>Diphyllobothrium<\/jats:italic> spp. cysts (<jats:styled-content style=\"fixed-case\">CYST<\/jats:styled-content>) with the counted number of <jats:italic>Diphyllobothrium<\/jats:italic> spp. plerocercoid larvae recovered using a conventional digestive technique (<jats:styled-content style=\"fixed-case\">LARV<\/jats:styled-content>). The aim was to determine the potential of using <jats:styled-content style=\"fixed-case\">CYST<\/jats:styled-content> as a simplified methodology for assessing <jats:italic>Diphyllobothrium<\/jats:italic> spp. infection in salmonids. In total, 365 brown trout and 424 Arctic charr were sampled from nine lakes in subarctic Norway. Strong correlation, significant linear relationship and large amount of explained variation were found between log<jats:sub>10<\/jats:sub><jats:styled-content style=\"fixed-case\">CYST<\/jats:styled-content> and log<jats:sub>10<\/jats:sub><jats:styled-content style=\"fixed-case\">LARV<\/jats:styled-content> in both fish species. The method had a slight, but not significant tendency to work better in charr compared to trout. In addition, absolute difference between <jats:styled-content style=\"fixed-case\">CYST<\/jats:styled-content> and <jats:styled-content style=\"fixed-case\">LARV<\/jats:styled-content> increased at parasite intensities &gt;100 indicating that the method has reduced functionality when estimating parasite intensity in heavily infected salmonid populations. However, overall, using this simplified and less time\u2010consuming methodology, a good indication of <jats:italic>Diphyllobothrium<\/jats:italic> spp. intensity, abundance and prevalence was obtained. We suggest that this method provides a sound proxy of the <jats:italic>Diphyllobothrium<\/jats:italic> spp. burden and have the potential to be used in parasite assessment during fish monitoring and fisheries management surveys, particularly if the time and resources for detailed parasite studies are not available.<\/jats:p>","DOI":"10.1111\/jfd.12566","type":"journal-article","created":{"date-parts":[[2016,10,13]],"date-time":"2016-10-13T23:51:29Z","timestamp":1476402689000},"page":"863-871","source":"Crossref","is-referenced-by-count":5,"title":["A
