Abstract
Bitterling Tanakia limbata is a temperate freshwater fish, distributes in fast-flowing creeks in central and southern Japan. In this study, the complete mitochondrial genome of T. limbata is sequenced to be 16,565 bp in length, including 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs, a control region and the origin of the light strand replication. The overall base composition of T. limbata in descending order is A 28.2%, C 27.5%, T 26.3%, and G 18.0%, with a slight A + T bias. The mitogenome sequence data may provide useful information to the population genetics analysis of T. limbata and the elucidation of evolutionary mechanisms in Cyprinidae.
