New Data on MtDNA Variability of Pond Smelt Hypomesus olidus (Osmeridae) from the Commander Islands in Comparison with Other Populations of the Species

Resumo

Sequencing of two regions of mitochondrial DNA, CytB (1124 bp) and COI (629 bp), is conducted for the first time for pond smelt Hypomesus olidus (Osmeridae) from the Commander Islands. The haplotypes identified, H1 and H2, differ by one mutation in the region of the COI gene. Haplotype H1 that belongs to the pond smelt from the Commander Islands was previously massively found in pond smelt of Azabache Lake. Haplotype H2 was not found previously and is probably unique to pond smelt from the Commander Islands.
