title: The complete mitochondrial genome of threatened chocolate mahseer (Neolissochilus hexagonolepis) and its phylogeny.
abstract: The chocolate mahseer (Neolissochilus hexagonolepis) is an important food and game fish of North Eastern India. To study the phylogenetic status we sequenced the complete mitochondrial genome of N. hexagonolepis. The mitogenome is 16,563 bp in length and composed of 13 protein coding genes, 22 tRNAs, 2 rRNAs and one putative control region. The overall base composition was A 31.8%, T 25.0%, G 15.8%, C 27.4% and A+T content 56.9%, G+C content 43.1%. The phylogenetic analysis using the complete mitochondrial genome revealed that the chocolate mahseer belonged to same clade of mahseer group of fishes but different from genera Barbus and Acrossocheilus. The present study will be helpful for the evolution and conservation genetic studies of N. hexagonolepis.
