Abstract
Predatory carp Chanodichthys erythropterus is a small-sized economic cyprinid fish distributed in East Asia. We sequenced its complete mitochondrial genome by PCR-based method. The mitochondrial DNA is packaged in a compact 16,629 base pair (bp) circular molecule with A + T content of 56.1%. It contains 22 transfer RNA genes, 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, and the non-coding control region (D-loop). All PCGs are initiated by ATG codons, except for COI, which uses GTG as its start codon. Of the 13 PCGs, 12 stop with TAA and TAG, while Cyt b uses incomplete termination codon T. All tRNAs possess the classic cloverleaf secondary structure except for tRNASer(AGN), which lacks the ‘‘DHU’’ stem.
