Abstract
The complete mitochondrial genomes were sequenced in two individuals of blunt-snouted lenok Brachymystax tumensis. The sizes of the genomes in the two isolates were 16,754 and 16,836; the difference was due to variable number of repeat sequences within the control region. The gene arrangement, base composition, and size of the two sequenced genomes are very similar to the B. lenok and B. lenok tsinlingensis genomes previously published (JQ686730 and JQ686731). However, the level of divergence inferred from 12 protein-coding genes (3.48%) indicated clear species boundaries between the lenok species.
