Mitochondrial haplotype diversity in 27 populations of brown trout, Salmo trutta L., in Austria was investigated by sequencing the 5' end of the mitochondrial DNA (mtDNA) control region. Although all populations are within the Danube drainage, 44% of all individuals carried Atlantic basin haplotypes. It is argued that the presence of these haplotypes in Austria primarily reflects introgression stemming from the stocking of hatchery-reared fish. However, several lines of evidence suggest that some natural colonization from Atlantic lineages may have contributed to the present haplotype diversity. Nonetheless, the more diverse Danubian clade is represented by regionally distinct haplotype diversity that should be protected from the continued introduction of domesticated strains of exogenous fish
通过对线粒体DNA（mtDNA）控制区5'端进行测序，研究了奥地利27个褐鳟种群（Salmo trutta L.）的线粒体单倍型多样性。尽管所有种群都在多瑙河流域内，但所有个体中有44%携带大西洋流域单倍型。有人认为，这些单倍型在奥地利的存在主要反映了源自孵化场养殖鱼类放流的基因渗入。然而，几条证据表明，大西洋谱系的一些自然定殖可能对目前的单倍型多样性有所贡献。尽管如此，更多样化的多瑙河分支由区域独特的单倍型多样性代表，应免受外来养殖品系鱼类的持续引入的影响。
