Forensic DNA barcoding identified seven species from trafficked fish maws and shark fins. Four CITES-listed species were detected, highlighting the need for robust wildlife crime enforcement.

Area of Science:

  • Forensic Science
  • Molecular Biology
  • Conservation Biology

Background:

  • Illegal wildlife trade threatens global biodiversity.
  • Accurate species identification is vital for combating wildlife crime.
  • Molecular methods offer advanced forensic species identification.

Purpose of the Study:

  • To identify species from trafficked fish maws and shark fins using DNA barcoding.
  • To estimate population sizes of identified species.
  • To assess the conservation status of identified species under CITES.

Main Methods:

  • DNA barcoding using COI and 16S gene regions.
  • Sequence alignment with NCBI GenBank and BOLD databases.
  • Phylogenetic analysis for species identification and population estimation.

Main Results:

  • Seven species were identified from 325 analyzed samples.
  • Four of the identified species are listed in CITES Appendix II.
  • The study involved 1777 fish maws and 18,170 shark fins.

Conclusions:

  • DNA barcoding is effective for identifying species in illegal wildlife trade.
  • The findings highlight significant trade in CITES-listed species.
  • Enhanced enforcement is needed to combat illegal wildlife trafficking.
