Molecular characterization of Channa species based on cytochrome c oxidase subunit I (COI) gene

Abstract:

Species level fish identification is traditionally based on morphological features. But due to morphological plasticity and high diversity and, in many cases, fish and their diverse developmental stages are difficult to identify by using morphological characteristics alone. For many animal taxa, sequence divergences within the 5′ region of the mitochondrial cytochrome oxidase subunit I (COI) gene are generally much greater between species than within species. This suggests that the approach is extensively applicable among phylogenetically distant animal groups. The present investigation successfully identified Channa punctata and Channa striata at molecular level using cytochrome oxidase subunit I (COI) gene. The inter- and intra-specific pairwise distance analysis using Neighbor-Joining K2P model have clearly stated prominent range of genetic distance between the Channa punctata and Channa striata species and demonstrate that both are distinct species.
