{"projectrec":{"ProID":1982,"StandardTitle":"Connectivity and demographic stability of North Sea sole populations","OrigTitle":"Connectiviteit en demografische stabiliteit van Noordzee tong populaties","Acronym":null,"AbstractEnglish":"This project aims at studying the connectivity and demographic stability of common sole populations (Solea solea) in the North Sea and adjacent waters.\r\nFirst, we will investigate the spatial and temporal connectivity between the major European spawning grounds and nursery areas of common sole. The origin of adults caught at the mixed feeding grounds will be determined and the relative importance of the different nurseries/spawning populations to the mixed stock will be estimated. A combination of both neutral genetic markers (mtDNA and microsatellite DNA) and ecological markers (elemental composition of fish otoliths) will be used. \r\nSecondly, DNA from historical fish otoliths (1955-1990) will be analyzed to examine the demographic stability of the North Sea sole stock and to investigate whether the fishery (mainly by beam trawl) has had an impact on the genetic diversity of the population.\r\nThe project is funded by IWT-Vlaanderen.","AbstractOtherLang":"Dit project bestudeert de connectiviteit en demografische stabiliteit van tongpopulaties (Solea solea) in de Noordzee en het Kanaal.\r\n\r\nTen eerste wordt de ruimtelijke en temporele connectiviteit onderzocht tussen de voornaamste Europese paaigronden en kinderkamers van tong. De mate van genmigratie wordt geschat en door middel van toewijzingsanalyses wordt het relatief belang van de verschillende kinderkamers en paaipopulaties bepaald. Hiervoor wordt een gecombineerde analyse van otoliet microchemie en neutrale genetische merkers (mtDNA en microsatelliet DNA) toegepast. \r\n\r\nTen tweede wordt DNA van historische otolietcollecties geanalyseerd (1955-1990) om de lange- termijn demografische stabiliteit van de Noordzee stock te onderzoeken. Er wordt nagegaan of visserij (vooral de intensieve boomkorvisserij) een impact heeft gehad op de genetische diversiteit van de Noordzee tong.\r\nHet project wordt gefinancierd door IWT-Vlaanderen.","DateLastModified":{"date":"2025-07-02 08:33:20.809226","timezone_type":1,"timezone":"+02:00"},"ParentProID":null,"BeginYear":2007,"EndYear":2011,"BMonth":1,"EMonth":2,"BeginMonth":"January","EndMonth":"February","OrigTitleLangCode":"nl","OrigTitleLangID":41,"OrigTitleLangNL":"Nederlands","OrigTitleLang":"Dutch","OtherAbstractLangCode":"nl","OtherAbstractLangID":41,"OtherAbstractLang":"Dutch","OtherAbstractLangNL":"Nederlands","Progress":"Completed","ProgressNL":"Afgelopen","PublicFlag":1,"CheckedFlag":0,"ND":"2007-03-22","UD":"2012-07-16","DMPFlag":0,"Budget":146032,"BudgetCurrency":"EUR"},"parent":null,"persons":null,"projects":null,"events":null,"datasets":null,"institutes":[{"instituterec":{"Acronym":null,"ProPartID":7763,"PublicFlag":1,"OrigNameLangCode":"en","OrigNameLangID":15,"FullOrigName":"Katholieke Universiteit Leuven;
