The distributions of both species on Chatham Rise overlapped geographically and by depth; the entire <i>P. bachus</i> distribution was encompassed by the <i>H. percoides</i> distribution. The diets of both species were dominated by crustaceans, but fish was also an important dietary component for <i>P. bachus</i>, while pelagic tunicates were important for <i>H. percoides</i>. Despite the overlap in spatial distribution, <i>P. bachus</i> and <i>H. percoides</i> had distinct diets with non-significant overlap, which will markedly reduce resource competition between these two species. The most important crustacean prey were Galatheidae (<i>Munida</i> sp.) and the pandalid shrimp <i>Notopandalus magnoculus</i> in <i>P. bachus</i>, and two-spined crab (<i>Pycnoplax victoriensis</i>) and isopods in <i>H. percoides.</i> Within-species variation in diet was influenced by predator location and ontogeny. The main ontogenetic shifts in diet were from small shrimps to larger fish prey for <i>P. bachus</i>, and from small crustaceans (mysids and galatheids) to larger crustaceans (scampi and crabs) for <i>H. percoides</i>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Dietary partitioning by two sympatric fish species, red cod (<i>Pseudophycis bachus</i>) and sea perch (<i>Helicolenus percoides</i>), on Chatham Rise, New Zealand","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":"Trophic relationships; spatial; niche","OtherDescriptors":null,"Notes":null,"AnaPub":2012,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2012-06-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000304592600006","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/17451000.2011.653543"},"refs":null,"anarec":{"AnaID":216502,"PubliDate":2012,"Pagination":"624-634","XtraPublOfAnaID":null,"ISBN":null,"Volume":"8","Issue":"7","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":72882,"SerRR":"Marine Biology Research.
