We assessed the utility of a new Bayesian method, which can estimate individual admixture coefficients even with data missing from the populations contributing to admixture. We applied the method to analyse the genetic contribution of domesticated brown trout (<i>Salmo trutta</i>) in samples of anadromous trout from two stocked populations with no genetic data available before stocking. Further, we estimated population level admixture proportions by the mean of individual admixture coefficients. This method proved more informative than a multidimensional scaling analysis of individual-based genetic distances and assignment tests. The results showed almost complete absence of stocked, domesticated trout in samples of trout from the rivers. Consequently, stocking had little effect on improving fisheries. In one population, the genetic contribution by domesticated trout was small, whereas in the other population, some genetic impact was suggested. Admixture in this sample of anadromous trout despite absence of stocked domesticated trout could be because of introgression by domesticated trout adopting a resident life history.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Admixture analysis and stocking impact assessment in brown trout (Salmo trutta), estimated with incomplete baseline data","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":"POPULATION-STRUCTURE, GENETIC INTROGRESSION, DNA, MICROSATELLITE, MARKERS, SALAR, HATCHERY, FISH, WILD, L.","Notes":null,"AnaPub":2001,"MonPub":null,"DateUpdate":"2001-11-16","DateCreate":"2001-11-14","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000170811300016","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":20326,"PubliDate":2001,"Pagination":"1853-1860","XtraPublOfAnaID":null,"ISBN":null,"Volume":"58","Issue":"9","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42535,"SerRR":"Canadian Journal of Fisheries and Aquatic Sciences = Journal canadien des sciences halieutiques et aquatiques.
