In this study, we determined the complete mitochondrial DNA sequence of the hybrid of Ctenopharyngodon idellus (♀) × Elopichthys bambusa (♂). The total length of the mitochondrial genome was 16,609 bp (accession number KM401549), with the base composition of 31.89% A, 26.33% C, 15.68% G, 26.11% T. The genome contained 2 ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes, and a major non-coding control region (D-loop region). Except for ND6 and 8 tRNAs, all other genes were encoded on the heavy strand. The arrangements of these genes were similar to that found in the other teleosts. The complete mitogenome may provide important date set for the study of genetic mechanism in the hybrid fish of Cyprinidae.
