Complete mitochondrial genome of the Yangtze grenadier anchovy, Coilia Brachygnathus (Clupeiformes: Engraulidae) from the upper Yangtze River

The Yangtze grenadier anchovy, Coilia brachygnathus, is a commercial fishery species in the middle and lower Yangtze River of China. Here, we describe a complete mitochondrial genome from the newly found population of C. brachygnahus in the upper Yangtze River. It was 16,857 bp in size and encodes for 2 rRNAs, 22 tRNAs, 13 protein-coding genes as well as a D-loop control region. Phylogenetic analysis confirmed the evolutionary relationship of the C. brachygnathus in the upper Yangtze to other five species of the genus Coillia. The mitochondrial genome would help to elucidate the origin of the new population of C. brachygnathus.
