摘要：

In this study, 229 DNA sequences of cytochrome oxidase subunit I gene (COI) from 158 marine fishes of Japan were employed to test the efficacy of species identification by DNA barcoding. The average genetic distance was 60-fold higher between species than within species, as Kimura two parameter (K2P) genetic distances averaged 17.6% among congeners and only 0.3% among conspecifics. There were no overlaps between intraspecific and interspecific K2P distances, and all sequences formed species units in the neighbor-joining dendrogram. Hybridization phenomena in two species (Kyphosus vaigiensis and Pterocaesio digramma) were also detected through searches in Barcode of Life Data Systems (BOLD). DNA barcoding provides a new way for fish identification. Crown Copyright (C) 2011 Published by Elsevier Ltd. All rights reserved.
