DNA barcoding for the identification of shark lips (鱼唇): A nationwide survey for analyzing a never investigated product in the Chinese market

A nationwide survey conducted in China aimed at authenticating species shark lips products (鱼唇) (n = 252) by full DNACOI barcoding (FDB; 652 bp) is presented. In addition, the efficiency of FDB and mini DNA barcode (MDB; 127 proposed Fields et al. (2015) (PloS one, 10, e0114844.) identifying detected this study was compared. Despite manufacturing process, total samples presented a medium low fragmentation degree, obtained from almost all except for two (99.2%) which MDB instead successfully obtained. Samples were allocated to level 96.4% cases. This confirms importance perform preventive evaluation degradation before selecting cost time-consuming procedures. Of 7 identified species, Prionace glauca most recovered (65.5%). The other six Carcharhinus falciformis (11.5%), Sphyrna lewini (6.7%), S. zygaena (3.6%), Isurus oxyrinchus C. longimanus (3.2%) sorrah (2.4%), 5 are threatened 4 subject global commerce regulation. Overall, issues discriminating among some spp. highlighted both using MDB. Outcomes need improve Chinese traceability system. fact, even though legislation seafood labelling supported an official system name attribution not always ensure sector safeguarding frauds, absent or weak certainly facilitate illegal practices.
