Sequencing of complete mitochondrial genome of sword prawn Parapenaeopsis hardwickii (Miers) (Crustacea, Decapoda, Penaeidae)

The sword prawn Parapenaeopsis hardwickii (Miers) (Crustacea, Decapoda, Penaeidae) is an important commercial fishery species, distributed in the East China Sea. In this study, we described the complete mitochondrial genome of P. hardwickii. The genome is 15,922 bp in length, encoding the standard set of 13 protein-coding genes, 22 tRNA genes and two rRNA genes, with circular organization. The overall A + T content is 67.20%; nucleotide frequency of the gene is as follows: A, 35.01%; C, 20.83%; G, 11.98%; T, 32.19%. The gene order of P. hardwickii is the same as Penaeus monodon and Fenneropenaeus chinensis, and it mainly retains as the Penaeidae ground pattern. The complete mitogenome sequence information of P. hardwickii would play an important part for further studies on molecular systematics and population genetics.
