Abstract

The review article focuses on the widespread application of DNA barcoding in the fishery background. With the advancement in science and technology, there is a dire necessity for upgradation in approaches for taxonomy, wildlife conservation, and health management in the fishery industry. To reduce invasiveness, illegal fishing, and health complications in fish in both marine as well aquaculture ecosystems different required mitigative measures need to be enforced. DNA barcoding is one important tool in biological science. It involves the sequencing of a small DNA segment called a ‘barcode’ of 648 base pairs. In animals and protists, the specific barcode is the mitochondrial gene cytochrome oxidase Ⅰ (COⅠ or COX 1) and it has proven to be extremely effective in identifying metazoans such as birds, butterflies, fish, flies, and many other animal groups. The use of DNA Barcoding has been proven to be effective in taxonomical classification of every group of organisms. In fishery, the application of barcoding created an avenue in marine conservation and aquaculture caretaking.
