Averaged over all samples, 90.2% of the 345 eels were infected with a mean intensity (averaged for all stages) of 17 nematodes. Thirty-one percent of all nematodes, which were adult worms or their remnants, were present in the swimbladder lumen, while the other 69% which consisted of the third or fourth larval stage and preadults were found in the swimbladder wall. No clear seasonal fluctuations in parasite prevalence or mean intensity were observed. Both L<sub>3</sub>-larvae and mature adult worms were present throughout the year. Eggs or L<sub>2</sub>-larvae were observed in 41% of the infected eels. This presence showed no seasonal pattern, though it was positively correlated with eel length: massive concentrations of L<sub>2</sub>-larvae were only found in eels bigger than 40 cm. A positive but weak correlation between eel length and number of adult nematodes in the swimbladder was significant, while no correlation was found between eel length and total parasite burden.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Population biology of <i>Anguillicola crassus</i> in the final host <i>Anguilla anguilla</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-19 01:31:08.996161","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1992,"MonPub":null,"DateUpdate":"2018-03-12","DateCreate":"2000-08-24","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1992KH04200002","VABBcode":null,"OpenAcc":1,"DOI":"10.3354/dao014163"},"refs":null,"anarec":{"AnaID":2883,"PubliDate":1992,"Pagination":"163-170","XtraPublOfAnaID":null,"ISBN":null,"Volume":"14","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42792,"SerRR":"Diseases of Aquatic Organisms.
