    Abstract

    Awareness of the evolutionary history, taxonomic position and ages of divergence (phylogeny) of an organism is indispensable and molecular taxonomy and population genetics gives a precise information on species diversity by detecting DNA level variations and thereby powerfully contribute to taxonomic and biodiversity research (Hajibabaei et al., 2007). DNA sequence level analyses changed the perspectives of conventional taxonomic methods which is based on the external morphological and meristic features that has its limitations for an accurate conclusion. A whole specimen itself may exhibit significant intraspecific variations and little interspecific variations in their morphology. Egg and larval stage identification is complicated than adult. These issues can be clearly resolved by DNA based techniques. As a commercially important commodity in the world market, incorrect labelling of fish causes risks in the quality and threat of adulteration in edible fish products. Molecular taxonomic techniques make fish identification possible even after cutting and processing of fishes (Fomina et al., 2020).
