Half-fin anchovy () is one of the most important economic fishes around the world. In the present study, we determined the complete mitochondrial DNA sequence and organization of . The entire mitochondrial genome is a circular-molecule of 16,215 bp in length, which encodes 37 genes in all. These genes comprise 13 protein-coding genes (ATP6 and 8, COI-III, Cytb, ND1-6, and 4L), 22 transfer RNA genes (tRNAs), and two ribosomal RNA genes (12S and 16S rRNAs), with gene arrangement and content basically identical to those of other species of Engraulidae. The result of phylogenetic analysis strongly supported that was first clustered together with and formed a monophyly in the genus , and then they constituted a sister-group relationship with two genus , and . It concluded that the should be classified into the genus . The present study also revealed the phylogenetic relationship of this genus at molecular levels. The complete mitochondrial genome sequence of can provide basic information for the studies on molecular taxonomy and phylogeny of teleost fishes.
半滑舌鳎是世界上最重要的经济鱼类之一。在本研究中，我们测定了半滑舌鳎的线粒体DNA全序列及其组织结构。线粒体全基因组是一个长度为16215 bp的环状分子，共编码37个基因。这些基因包括13个蛋白质编码基因（ATP6和8、COI - III、Cytb、ND1 - 6和4L）、22个转运RNA基因（tRNAs）和两个核糖体RNA基因（12S和16S rRNAs），其基因排列和内容与其他鳎科鱼类基本相同。系统发育分析结果强烈支持半滑舌鳎首先与[某物种]聚集在一起，并在舌鳎属中形成一个单系群，然后它们与[另外两个属]构成姐妹群关系。得出结论，半滑舌鳎应归入舌鳎属。本研究还在分子水平上揭示了该属的系统发育关系。半滑舌鳎的线粒体全基因组序列可为硬骨鱼类的分子分类和系统发育研究提供基础信息。
