Two distinct lineages that represent the Atlantic and Mediterranean regions have been previously identified, with a hybrid zone close to the Almeria–Oran front. The presence of fine-scale population structure within the Northeast Atlantic region is less clear. Here, we investigated population structure in adult samples obtained from the northern part of the Atlantic range surrounding the UK, Ireland, Belgium, Germany, France, the Netherlands, and Norway, along with outgroups from Portugal and the Mediterranean, using a panel of 41&nbsp;K single nucleotide polymorphism markers. Population structure among Northeast Atlantic Ocean samples was weak in both spawning—(<i>F</i><sub>ST&nbsp;</sub>=&nbsp;0.00022) and feeding—(<i>F</i><sub>ST&nbsp;</sub>=&nbsp;0.00032) season data sets, with small pairwise <i>F</i><sub>ST</sub> values between sample pairs. However, average <i>F</i><sub>ST</sub> was larger between spawning samples than between feeding samples, with a pattern of isolation-by-distance among the spawning samples, but not the feeding samples, suggesting some biologically meaningful population structure. The largest pairwise <i>F</i><sub>ST</sub> values at both International Council for the Exploration of the Sea (ICES) rectangle and division scales involved a sample from the west of Ireland. We found no evidence of a gradient in “Mediterranean” ancestry among samples collected around the UK in our data set or in a reanalysis of a published data set where such a pattern had been previously identified. In summary, there was no evidence that sea bass in different ICES divisions within the Northeast Atlantic Ocean represents genetically separate populations. Further work is required to reconcile evidence from tagging and modelling studies that suggest the potential for demographic independence with the genetic data.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"High-density SNP panel provides little evidence for population structure in European sea bass (<i>Dicentrarchus labrax</i>) in waters surrounding the UK","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:33:03.355911","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"SNPs; sea bass; connectivity","OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-10-21","DateCreate":"2025-10-21","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001487385300001","VABBcode":null,"OpenAcc":1,"DOI":"10.1093/icesjms/fsaf064"},"refs":null,"anarec":{"AnaID":435543,"PubliDate":2025,"Pagination":"fsaf064","XtraPublOfAnaID":null,"ISBN":null,"Volume":"82","Issue":"5","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44710,"SerRR":"ICES Journal of Marine Science.
