Despite its considerable importance to fisheries, knowledge on this marine ecosystem is only limited. Here, parasites were used as indicators to gain insight into the host ecology and food web of two pelagic fish species, the commercially important species <i>Trichiurus lepturus</i> Linnaeus, 1758, and <i>Nealotus tripes</i> Johnson, 1865<i>.</i> Fish specimens of <i>T. lepturus</i> (<i>n</i> = 104) and <i>N. tripes</i> (<i>n</i> = 91), sampled from the Canary Current System off the Senegalese coast and Cape Verde Islands, were examined, collecting data on their biometrics, diet and parasitisation. In this study, the first parasitological data on <i>N. tripes</i> are presented. <i>T. lepturus</i> mainly preyed on small pelagic Crustacea and the diet of <i>N. tripes</i> was dominated by small mesopelagic Teleostei. Both host species were infested by mostly generalist parasites. The parasite fauna of <i>T. lepturus</i> consisted of at least nine different species belonging to six taxonomic groups, with a less diverse fauna of ectoparasites and cestodes in comparison to studies in other coastal ecosystems (Brazil Current and Kuriosho Current). The zoonotic nematode <i>Anisakis pegreffii</i> occurred in 23% of the samples and could pose a risk regarding food safety. The parasite fauna of <i>N. tripes</i> was composed of at least thirteen species from seven different taxonomic groups. Its most common parasites were digenean ovigerous metacercariae, larval cestodes and a monogenean species (Diclidophoridae). The observed patterns of parasitisation in both host species indicate their trophic relationships and are typical for mesopredators from the subtropical epi- and mesopelagic. The parasite fauna, containing few dominant species with a high abundance, represents the typical species composition of an eastern boundary upwelling ecosystem.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Mesopredatory fishes from the subtropical upwelling region off NW-Africa characterised by their parasite fauna","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Food-web; Subtropical East-Atlantic; Eastern boundary upwelling ecosystem; Canary Current ","OtherDescriptors":null,"Notes":null,"AnaPub":2018,"MonPub":null,"DateUpdate":"2018-09-04","DateCreate":"2018-09-04","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000441110900005","VABBcode":null,"OpenAcc":1,"DOI":"10.7717/peerj.5339"},"refs":null,"anarec":{"AnaID":300722,"PubliDate":2018,"Pagination":"e5339","XtraPublOfAnaID":null,"ISBN":null,"Volume":"6","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":242055,"SerRR":"PeerJ.
