The complete mitochondrial genome information can play an important role in species identification, phylogeny, evolution research, genetic differentiation, and diversity. Here we determined the complete mitochondrial genome sequence of Elagatis bipinnulata (Perciformes: Carangidae). This circular genome was 16 542 bp in length, and included all 37 typical mitochondrial genes, containing 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and a putative control region. The gene order of E. bipinnulata was identical to that observed in most other vertebrates. Of 37 genes, 28 were encoded by heavy strand, while the other ones were encoded by light strand. According to the phylogenetic analysis based on 13 concatenated protein-coding genes, E. bipinnulata was genetically closer to the species of genus Seriola compared with any other species within Perciformes. This work can provide helpful data for further studies on population genetic diversity and molecular evolution.
完整的线粒体基因组信息在物种鉴定、系统发育、进化研究、遗传分化和多样性方面可发挥重要作用。在此，我们测定了杜氏鰤（鲈形目：鲹科）的完整线粒体基因组序列。这个环状基因组长度为16542 bp，包含所有37个典型的线粒体基因，包括13个蛋白质编码基因、22个tRNA基因、两个rRNA基因和一个假定的控制区。杜氏鰤的基因排列顺序与大多数其他脊椎动物中观察到的相同。在这37个基因中，28个由重链编码，而其他基因由轻链编码。根据基于13个串联蛋白质编码基因的系统发育分析，与鲈形目内的任何其他物种相比，杜氏鰤在遗传上与鰤属的物种关系更近。这项工作可为进一步研究种群遗传多样性和分子进化提供有用的数据。
