The 1071 fish examined had an approximate ocean residence time no longer than 3\u2003months. A high prevalence of degenerative liver lesions, renal myxosporean parasites and a low prevalence of skin lesions and sea lice were observed. No indications of viral or bacterial diseases were detected in either year. The monthly prevalence of sea lice in 2007 (18\u201351%) was higher than in 2008 (1\u201326%), and the infestation density exceeded the lethal threshold in only two fish. Degenerative hepatic lesions and renal myxosporean parasites occurred in approximately 40% of the pink salmon examined in June of both years, and the peak monthly prevalence of hepatocellular hydropic degeneration was greater in 2007 (32%, in May) than in 2008 (12%, in June). Logistic regression analysis found skin lesions and hepatocellular hydropic degeneration significantly associated with sea lice. Most parasites and lesions occurred during both years, but the prevalence was often higher in 2007. Fish weight was 35% less in June 2007 than in June 2008, but condition factor was not different. Further research is required to monitor inter\u2010annual variations and aetiology of the liver lesions and to assess their potential role on pink salmon survival.<\/jats:p>","DOI":"10.1111\/j.1365-2761.2011.01330.x","type":"journal-article","created":{"date-parts":[[2012,1,11]],"date-time":"2012-01-11T09:38:34Z","timestamp":1326274714000},"page":"137-151","source":"Crossref","is-referenced-by-count":22,"title":["Parasites
