Abstract This study was conducted to identify the species origin of 91 samples of frozen fish products and highly processed, pre-packaged fish products collected from supermarkets using DNA barcoding technique based on homologous sequence analysis of the COI and 16S rRNA genes. The results confirmed that both COI and 16S rRNA gene sequencing were useful for species authentication of fish products. The species origin of 66 of 79 (83.54%) frozen fish products and 7 of 12 (58.33%) highly processed, pre-packaged fish products was consistent with the product claims, which indicated that some problems such as mislabeling and ambiguous ingredient designation of fish products existed in the fish market. This research can provide technical support for the supervisory authorities concerned .
