Abstract
DNA barcoding appears to be a promising approach for taxonomic identification, characterization, and discovery of newer species, facilitating biodiversity studies. It helps researchers to appreciate genetic and evolutionary associations by collection of molecular, morphological, and distributional data. Fish DNA barcoding, based on the sequencing of a uniform area of Cytochrome C Oxidase type I (COI) gene, has received significant interest as an accurate tool for species identification, authentication, and phylogenetic analysis. The aim of this review article was to investigate recent global status, approaches, and future direction of DNA barcoding in fisheries sectors. We have tried to highlight its possible impacts, complications, and validation issues at species levels for biodiversity analysis. Moreover, an effort has been put forward to understand issues related to various marker genes associated with barcode process as primer sequences and have concluded barcode promotion as an indispensable tool of molecular biology for the development of taxonomic support systems.
