The complete mitochondrial genome of Zacco platypus (Cypriniformes, Cyprinidae), which has broader distribution range and diverse genetic structure than other species under the genus Zacco, was first determined in this study. The mitochondrial genome is 16,612 base pairs (bp) in length, encoding 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs and 1 non-coding control region. Its gene arrangement and translation direction were identical to those of other typical vertebrate. Control region (D-Loop), of 929 bp lengths long, is located between tRNA(Pro) and tRNA(Phe). The overall base composition of the heavy strand shows T 27.02%, C 26.23%, A 28.94% and G 17.82%, with a slight AT bias of 55.95%.
