Background and aims. Sillago sihama is one of the commercially important fish species and the mitochondrial genome of S. sihama was determined. Results. The mitogenome of S. sihama is 16,599 bp in length. It contains 37 mitochondrial genes (2 ribosomal RNA genes, 22 transfer RNA genes, and 13 protein-coding genes) as found in other vertebrates. It represents the first complete mitogenome accessioned for Sillago fishes (GenBank Accession No. JQ048935). The structure and organization of the control region (D-loop) in S. sihama is similar to that of other teleost fish and vertebrates (all containing conserved sequence block and high variation block). Conclusion. The phylogenetic analyses based on the mtDNA sequence of S. sihama supported a close relationship with Carangidae, consistent with taxonomic hypothesis based on morphology. Moreover, the high sequence variability of control region (haplotype diversity, H-d = 1.000) indicated the potential utility as marker for population-level studies.
