The complete mitochondrial genome of the juvenile Atlantic bluefin tuna Thunnus thynnus (Perciformes, Scombridae).

The complete mitochondrial genome of the juvenile Atlantic bluefin tuna Thunnus thynnus collected from Sea of Japan was determined by next-generation sequencing. The mitogenome is a circular molecule 16,529 bp in length, including the typical structure of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and a control region. The TAS, central CSB and CSB were detected in the control region. The gene contents of the mitogenome are identical to those observed in most bony fishes.
