In many cases commercial frauds are related to taxonomic problems:species can be identified by a common vernacular name,which can correspond to different taxa. Barbuto et al. (2010) reported the case of two Mustelus species (M. mustelus and M. asterias) which are sold in Italy under the same commercial name ‘Palombo’. In other cases, different vernacular names are associated with the same species in different regions (Burgess et al., 2005). To avoid frauds and mislabeling, the vernacular name of edible species should be written together with the correct scientific name, and the reference to the DNA barcode sequence.
