DNA-barcoding of perch-like fishes (Actinopterygii: Perciformes) from far-eastern seas of Russia with taxonomic remarks for some groups.

The analysis of variation among 203 nucleotide sequences of Co-1 gene (DNA-barcode) for 45 species, 31 genera and 7 families of the order Perciformes from the Far Eastern seas of Russia has been performed. As a result, 42 species (93.3%) can be unambiguously identified using molecular DNA-barcode at Co-1, whereas more variable markers are required for other species (6.
