The complete mitochondrial genome of Hypomesus olidus (Osmeriformes: Osmeridae)

Abstract

Pond smelt Hypomesus olidus is a small-sized economic species of freshwater fish with delicious meat and high output. In this study, the complete mitochondrial genome of H. olidus sequenced to be 16,786 bp in length, including 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs and a control region. The overall base composition of H. olidus is 24.3% for A, 27.3% for T, 29.2% for C and 19.2% for G, with a slight A þ T bias. The mitogenome sequence data may provide useful information to the population genetics analysis of H. olidus and the elucidation of evolutionary mechanisms in Hypomesus fish.

Complete mitochondrial genome sequence and SNPs of the Korean smelt Hypomesus nipponensis (Osmeriformes, Osmeridae)

“…Phylogenetic analysis using the Cox1 gene confirmed the current taxonomic classification of H. nipponensis (Figure 1). In fact, the mitogenome of H. nipponensis exihibited 99% sequence similarity with H. olidus, with the same gene arrangement, composition, and size (Li et al 2010;Bai et al 2017). As can be seen in Figure 1, the Cox1 gene is also very similar between the two species.…”
