Molecular Identification of Ribbon Fish (Eupleurogrammus Sp.) Using Partial Sequence of Mitochondrial COI Gene

Dry fish is considered as a delicacy in the menu of many people Bangladesh. The most economically important marine and freshwater dried fishes are ribbon fish, bombay duck, olive barb, pomfret, shrimp, etc. In this study, fresh sample was collected from Cox's Bazar morphologically identified fish. confirmed through molecular technique using mitochondrial COI gene (cytochrome c oxidase subunit I) to avoid morphological ambiguity, which first reported data Partial sequence amplified genus specific universal primer set. target nucleotide determined successfully with 616 bp length Eupleurogrammus sp. Within region GC AT content were 45.5% 54.5%, respectively. 16.88% interspecific polymorphism observed when compared other species under Gen Bank database. This will be used bar code for authentic identification at level. Bangladesh J. Zool. 50 (2): 231-238, 2022
