Several methods for establishing Ichthyophonus infections in laboratory challenges were examined. Infections were most effectively established after intraperitoneal (IP) injections with suspended parasite isolates from culture or after repeated feedings with infected fish tissues. Among groups that were offered the infected tissues, infection prevalence was greater after multiple feedings (65%) than after a single feeding (5%). Additionally, among groups that were exposed to parasite suspensions prepared from culture isolates, infection prevalence was greater after exposure by IP injection (74%) than after exposure via gastric intubation (12%); the flushing of parasite suspensions over the gills did not lead to infections in any of the experimental fish. Although the consumption of infected fish tissues is unlikely to be the primary route of Ichthyophonus sp. transmission in wild populations of Pacific Herring, this route may contribute to abnormally high infection prevalence in areas where juveniles have access to infected offal.<\/jats:p>\n               <jats:p>Received June 25, 2015; accepted September 12, 2015<\/jats:p>","DOI":"10.1080\/08997659.2015.1095809","type":"journal-article","created":{"date-parts":[[2015,12,14]],"date-time":"2015-12-14T16:36:20Z","timestamp":1450110980000},"page":"217-221","update-policy":"https:\/\/doi.org\/10.1080\/tandf_crossmark_01","source":"Crossref","is-referenced-by-count":6,"title":["Infecting Pacific Herring with <i>Ichthyophonus<\/i> sp. in the Laboratory"],"prefix":"10.1093","volume":"27","author":[{"given":"P.
