A midwater sampler-trawl (Hamburg Plankton Net) was used to collect zooplankton and fish larvae. Mean relative biomass of Antarctic krill <i>Euphausia superba</i>, in the area north of Continental Shelf, was 9.3 g/1000 m<sup>3</sup> of filtered water with a mean density of 10.9 ind./1000 m<sup>3</sup>. Ice krill <i>Euphausia crystallorophias</i> replaced the Antarctic krill in dominance in the High Antarctic Zone (south of 74°), with a mean relative biomass of 3.0 g/1000 m<sup>3</sup> and a mean density of 19.1 ind./1000 m<sup>3</sup>. The present data have demonstrated that in the Ross Sea the two species of euphausiid inhabited different areas during the summer period. Oceanographic data indicate that both euphausiid species were found in surface waters, <i>Euphausia crystallorophias</i> in proper Ross Sea water, and <i>Euphausia superba</i> in Antarctic Surface Water. The catch data of <i>Euphausia superba</i> were characterised by the complete absence of larval stages, scarce occurrence of juveniles and composed primarily of large adult stages, whereas the overall length frequency distribution of <i>Euphausia crystallorophias</i> was characterised by a first mode of juvenile individuals and a second mode consisting of sub-adults and adults.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Krill of the Ross Sea: distribution, abundance and demography of <i>Euphausia superba</i> and <i>Euphausia crystallorophias</i> during the Italian Antarctic expedition (January-February 2000)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-03 01:30:54.799248","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"abundance, Antarctica, krill, demography, distribution, Euphausia crystallorophias, Euphausia superba, Ross Sea","OtherDescriptors":"Antarctica; krill; demorgraphy; <i>Euphausia superba</i>; <i>Euphausia crystallorophias</i>; Ross Sea","Notes":null,"AnaPub":2002,"MonPub":null,"DateUpdate":"2015-07-06","DateCreate":"2002-08-14","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000175913100004","VABBcode":null,"OpenAcc":1,"DOI":"10.3989/scimar.2002.66n2123"},"refs":null,"anarec":{"AnaID":26354,"PubliDate":2002,"Pagination":"123-133","XtraPublOfAnaID":null,"ISBN":null,"Volume":"66","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43791,"SerRR":"Scientia Marina (Barcelona).
