Abstract

ABSTRACT – The authors developed and evaluated DNA barcodes for use in differentiating domestic and imported fish species (1). First, we sequenced part of the cytochrome oxidase I (COI) gene in accordance with standard DNA barcoding protocols. These alignments allowed the development and analyses of consensus barcode sequences for each species and comparison with limited sequences in public databases (GenBank and Barcode of Life Data Systems). In this study, we report test regarding Mediterranean fish identifications. Experimental validation parameters were obtained on certain specie-specific DNA and sensitivity, specificity, reproducibility, concordance tests role out value as 100%, 100%, 99%, 99.8% respectively. The advantage of using “CO1”gene is that it is short enough to be sequenced quickly and cheaply yet long enough to identify variations among species, and enabling identifications where traditional methods are not “applicable, such as for immature stages or body fragments (2). FISH-BOL will also provide a powerful tool for enhanced understanding of the natural history and ecological interactions of fish species.
