1 Research Institute for Aquaculture No1, Centre for Aquaculture Biotechnology, Bac Ninh, Viet Nam DOI : 10.4194/1303-2712-v18_3_11 Viewed : 267 - Downloaded : 166 Nucleotide sequences of the Cytochrome oxidase subunit I gene and Cytochrome b were analyzed for Ö10 processed fish products collected from supermarkets in Hanoi, Viet Nam. The similarity between our results and published data from the NCBI and BOLD was compared to identify species. This molecular analysis showed that the common names of only 4 of these products matched with their corresponding scientific names. The other six were mislabeled with an important mislabeling from P. hypophthalmus into P. boucourti. Although no commercial frauds were found in these mislabelled products, the correct scientific names of fish species should be labelled for the processed products as they are in supermarkets.
