To investigate light responses in L. salmonis copepodites, a non-intrusive experimental system was designed to measure behavioral responses in a 12.5-l volume using machine vision technology and methodology. The experimental system successfully tracked the collective movement patterns of the sea lice population during exposure to different light stimuli emitted from alternating zones in the system. This system could further be used to study behavioral responses to different physical cues of various developmental stages of sea lice or other zooplankton.<\/jats:p>","DOI":"10.1242\/bio.050724","type":"journal-article","created":{"date-parts":[[2020,6,25]],"date-time":"2020-06-25T15:35:16Z","timestamp":1593099316000},"source":"Crossref","is-referenced-by-count":4,"title":["A machine vision system for tracking population behavior of zooplankton in small-scale experiments: a case study on salmon lice (<i>Lepeophtheirus salmonis<\/i> Kr\u00f8yer, 1838) copepodite population responses to different light stimuli"],"prefix":"10.1242","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6061-3325","authenticated-orcid":false,"given":"Bjarne","family":"Kv\u00e6stad","sequence":"first","affiliation":[{"name":"SINTEF Ocean, Environment and New Resources, Bratt\u00f8rkaia 17C, NO-7010 Trondheim, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0269-2974","authenticated-orcid":false,"given":"Trond","family":"Nordtug","sequence":"additional","affiliation":[{"name":"SINTEF Ocean, Environment and New Resources, Bratt\u00f8rkaia 17C, NO-7010 Trondheim, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9375-7875","authenticated-orcid":false,"given":"Andreas","family":"Hagemann","sequence":"additional","affiliation":[{"name":"SINTEF Ocean, Environment and New Resources, Bratt\u00f8rkaia 17C, NO-7010 Trondheim, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","published-online":{"date-parts":[[2020,6,25]]},"reference":[{"key":"2021042622461448800_BIO050724C1","doi-asserted-by":"publisher","first-page":"211","DOI":"10.3354\/meps186211","article-title":"Wavelength-specific behaviour in Lepeophtheirus salmonis and Calanus finmarchicus to ultraviolet and visible light in laboratory experiments (Crustacea: Copepoda)","volume":"186","author":"Aarseth","year":"1999","journal-title":"Mar.
