Abstract
We describe the complete mitochondrial genome sequence of Oncorhynchus masou formosanus, which is a critically endangered landlocked salmon of Taiwan by using next-generation sequencing. The circle genome (16,653 bp) has the typical vertebrate mitochondrial gene arrangement, consisting of 13 protein-coding genes, 22 tRNA genes, two rRNA genes and a non-coding control region. The overall base composition of O. m. formosanus is 28.6% for A, 26.8% for T, 16.5% for G and 28.1% for C, with a slight AT bias of 55.4%.
