DNA bar-coding is regarded as an competent equipment, a system  designated to provide rapid and accurate identification of species along with phylogeny of organism focused on the use of short, standardized genetic region, mitochondrial cytochrome c oxidase 1 (COI) gene fragment. At gene level the modern technique of DNA bar-coding approved to be conducive or fruitful. With the aim  of setting reference segment depository and tracking of DNA bar-coding program advancement at local level global investigation alliance hub called the fish bar-code of life campaign FISH-BOL was set up as DNA bar-code library. The objective of this chapter is to examine ongoing status phase of fish species identification using DNA bar-coding, strategies and practice as well as future orientation of DNA bar-coding in fishery speciation and management science. Existing condition of taxonomical works in which DNA barcodes are used in relation with fish taxonomy in India has been assessed and a comprehensive analysis of the surviving literature has been accomplished at the local, national and international level. The research outcome clarifies that the DNA bar-coding research in aquatic marine invertebrates is quietly into juvenile phase in India.
