摘要：

The utilization of molecular tools for the certification of fishery products has been increasing over the last years. In general, economically important species are replaced by less valuable species, characterizing a commercial fraud. We evaluated the authenticity of 107 frozen fillets tagged as Gurijuba (Sciades parkeri) and Uritinga (Sciades proops) from local markets in northern amazon coast by sequencing two mitochondrial genes: Cytochrome oxidase subunit I and cytochrome b (Cyt b). About 16% of fillets putatively related to S. parkeri were replaced by S. proops. The Gurijuba faces high fishing pressure, being currently listed by the International Union for Conservation of Nature as vulnerable. Forensic analysis with DNA markers, proved to be highly efficient in the discrimination of the processed seafood products, providing unequivocal identification of species, revealing commercial fraud in the fillets of the Gurijuba, and revealing the utility of Cytb sequences as barcode in fishes.
