Enhanced phylogeographic information about Austrian brown trout populations derived from complete mitochondrial control region sequences

Complete DNA sequences of the control region revealed a more fine-scale genetic structuring within and among Austrian brown trout Salmo trutta populations providing the opportunity for gene frequency analyses in the phylogeographic context. Ninety-two individuals (75%) were assigned to nine Danubian haplotypes and 31 individuals (25%) comprised seven Atlantic haplotypes of northern European origin. Three of the Atlantic haplotypes were also found in an Austrian hatchery breeding stock.
