摘要： Half-fin anchovy (Setipinna tenuifilis) 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 S. tenuifilis. 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 S. tenuifilis was first clustered together with Setipinna melanochir and formed a monophyly in the genus Coilia, and then they constituted a sister-group relationship with two genus Engraulis, and Stolephorus. It concluded that the S. tenuifilis should be classified into the genus Setipinna. The present study also revealed the phylogenetic relationship of this genus at molecular levels. The complete mitochondrial genome sequence of S. tenuifilis can provide basic information for the studies on molecular taxonomy and phylogeny of teleost fishes.
