In this study, the complete mitogenome sequence of the Mekong tiger fish Datnioides undecimradiatus (Perciformes: Datnioididae) has been sequenced by next-generation sequencing method. The assembled mitogenome consisting of 16,534 bp, includes 13 protein-coding genes, 22 transfer RNAs and 2 ribosomal RNAs genes. The overall base composition of the Mekong tiger fish is 27.9% for A, 30.69% for C, 16.51% for G, 24.91% for T and show 77% identities to Anoplocapros lenticularis(GenBank accession no. NC011319.1). The complete mitogenome of the Mekong tiger fish provides essential and important DNA molecular data for further phylogeography and evolutionary analysis for Datnioididae family.
