利用线粒体DNA（mtDNA）标记和核DNA（nDNA）标记，对北海道附近捕获的野生史氏鲟（Amur sturgeonAcipenser schrenckii）及其杂交种的5个个体进行了遗传学分析。遗传分析表明，5条鱼中有2条的mtDNA单倍型为达氏卡卢加，而nDNA标记显示博塔A。schrenckiiandH. dauricusgenotypes，指的是杂交起源。其他三条鱼都是纯净的。结果表明，mtDNA和nDNA标记的联合应用对鲟鱼种的正确鉴定具有重要意义。
Genetic characterization was performed in five individuals of wild Amur sturgeonAcipenser schrenckii,and/or its presumed hybrid caught around Hokkaido, using a mitochondrial DNA (mtDNA) marker and two markers of nuclear DNA (nDNA). Genetic analyses indicated that two of the five fish had the mtDNA haplotype of Kaluga,Huso dauricus, whereas the nDNA markers indicated signs for bothA. schrenckiiandH. dauricusgenotypes, referring to a hybrid origin. The other three fish were plausibly pureA. schrenckii.The results indicated the importance of combined usage of mtDNA and nDNA markers for correct species identification in sturgeon.
