In this study, the complete mitochondrial DNA sequence was obtained from . The full length of mitogenome was 16 018 bp, including 20 transfer RNA genes, a 16S ribosomal RNA genes and an incomplete 12S rRNA, 12 protein-coding genes and an incomplete ND6 protein-coding gene, and 2 non-coding regions: control region (D-loop) and origin of light-strand (L-strand) replication (OL). Most genes were located on the heavy-strand (H-strand), while ND6 and seven tRNA genes were located on the L-strand. 's mitogenome was comprised of 24.52% for A, 25.44% for C, 20.38% for G and 29.66% for T, with a higher A + T content (54.18%). From the NJ phylogenetic tree, it revealed that 's was genetically closest to species among seven species within suborder Notothenioidei. This study could lay the foundation for the future studies in species identification, taxonomic status, molecular systematics, stock evaluation and conservation genetics for 's.
在本研究中，从……获得了完整的线粒体DNA序列。线粒体基因组全长16018 bp，包括20个转运RNA基因、1个16S核糖体RNA基因和1个不完整的12S rRNA、12个蛋白质编码基因和1个不完整的ND6蛋白质编码基因，以及2个非编码区：控制区（D-loop）和轻链（L-strand）复制起点（OL）。大多数基因位于重链（H-strand）上，而ND6和7个tRNA基因位于轻链上。……的线粒体基因组中，A占24.52%，C占25.44%，G占20.38%，T占29.66%，A+T含量较高（54.18%）。从邻接系统发育树可知，在南极鱼亚目七个物种中，……与……在遗传上最为接近。本研究可为……的物种鉴定、分类地位、分子系统学、种群评估和保护遗传学的未来研究奠定基础。
