Abstract
Animal DNA barcoding allows researchers to identify different species by analyzing a short nucleotide sequence, typically the mitochondrial gene cox1. In this paper, we use DNA barcoding to genetically identify seafood samples that were purchased from various locations throughout Italy. We adopted a multi-locus approach to analyze the cob, 16S-rDNA and cox1 genes, and compared our sequences to reference sequences in the BOLD and GenBank online databases. Our method is a rapid and robust technique that can be used to genetically identify crustaceans, mollusks and fishes. This approach could be applied in the future for conservation, particularly for monitoring illegal trade of protected and endangered species. Additionally, this method could be used for authentication in order to
detect mislabeling of commercially processed seafood.
