“…Liu et al [63] analyzed the species composition of shark meat from fish markets in Taiwan, pointing the species Alopias pelagicus, Carcharhinus falciformis, Prionace glauca, and Isurus oxyrinchus as the most prevalent species on the Taiwan fin trade, while some CITES species were also found such as the great white Carcharodon carcharias, the oceanic whitetip shark Carcharhinus longimanus, and two hammerhead sharks Sphyrna zygaena and Sphyrna lewini. Espinoza et al [68] presented the Mexican first efforts to combat the shark fin trade on the Mexican Pacific waters. The authors used DNA barcoding on the identification of six shark species (cf.…”

Worshipped and revered in several Indo-Pacific countries, and mostly feared among the western world, sharks are an old group of vertebrates dating back to the Devonian-Silurian boundary (~400Ma). Constantly represented as human predator by occidental movies, sharks have a spiritual appeal for several Indo-Pacific cultures. In contrast with this spiritual significance, in China sharks are a fierce animal believed to give strength and health for those whom consume their fins. They are also considered as a signal of prosperity and wealth. Fished for their meat and fins, several species are considered under high threat and are now facing extinction, with about 93% of nominal species included on the IUCN Red List. Mainly relying on the inefficiency of law enforcement authorities, the shark finning industry is a growing business with global scale actors and consequences. Understand the relation between spiritual beliefs, wealth and vitality, and the consumption of shark fins and meat is needed to precisely delineate the shark finning problem and to the development of efficient management and conservation policies. Molecular methods provide a valuable option for the identification of shark meat and body parts such as fins, although it still not consensual which one is the most appropriate.

“…In the last decade, DNA barcoding was proposed as a molecular identification tool [10] and was proved as a powerful approach to quickly asses biodiversity, including marine biota [11,12]. The use of DNA barcoding is advantageous to resolve many problems in the field of marine life studies [13], like identifying the occurrence of cryptic species which are common in marine ecosystem [11], improving identification of larvae and the relations with adult forms [13], identifying non-indigenous and potentially invasive species [14], detecting the illegal trade of regulated and protected species in processed products [15] or identifying species used in shark finning [16]. Also, DNA barcoding has a great potential for monitoring biodiversity changes (e.g.…”

DNA barcoding in the Southeast Pacific marine realm: Low coverage and geographic representation despite high diversity

et al. 2020

The Southeast Pacific comprises two Large Marine Ecosystems, the Pacific Central-American Coastal and the Humboldt Current System; and is one of the less well known in the tropical subregions in terms of biodiversity. To address this, we compared DNA barcoding repositories with the marine biodiversity species for the Southeast Pacific. We obtained a checklist of marine species in the Southeast Pacific (i.e. Colombia, Ecuador, Chile, and Peru) from the Ocean Biodiversity Information System (OBIS) database and compared it with species available at the Barcoding of Life Data System (BOLD) repository. Of the 5504 species records retrieved from OBIS, 42% of them had at least one registered specimen in BOLD (including specimens around the world); however, only 4.5% of records corresponded to publicly available DNA barcodes including specimens collected from a Southeast Pacific country. The low representation of barcoded species does not vary much across the different taxonomic groups or within countries, but we observed an asymmetric distribution of DNA barcoding records for taxonomic groups along the coast, being more abundant for the Humboldt Current System than the Pacific Central-American Coastal. We observed high-level of barcode records with Barcode Index Number (BIN) incongruences, particularly for fishes (Actinopterygii = 30.27% and Elasmobranchii = 24.71%), reflecting taxonomic uncertainties for fishes, whereas for Invertebrates and Mammalia more than 85% of records were classified as data deficient or inadequate procedure for DNA barcoding. DNA barcoding is a powerful tool to study biodiversity, with a great potential to increase the knowledge of the Southeast Pacific marine biodiversity. Our results highlight the critical need for increasing taxonomic sampling effort, the number of trained taxonomic specialists, laboratory facilities, scientific collections, and genetic reference libraries.
