For several shark species listed under Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), this limits external verification of source populations supplying global trade hubs. Here, we assess whether nuclear genomic approaches can be applied to market\u2010derived bull shark (\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>Carcharhinus leucas<\/jats:italic>\n                    <\/jats:styled-content>\n                    ) fins to determine their population of origin. We analysed dried fin trimmings collected from retail vendors in Hong Kong SAR, one of the world's largest dried shark fin trade hubs, using a targeted DArTcap single nucleotide polymorphism (SNP) panel, originally developed for population genomic studies of this species. Despite substantial DNA degradation, genomic libraries were successfully obtained for most samples, yielding sufficient SNP data to perform robust provenance and sex assignment. Using a Bayesian mixed\u2010stock analysis, most fin samples were assigned to the Indo\u2013West Pacific (71.4%), with smaller contributions from the western Atlantic (22.6%) and eastern Pacific (3.0%). Genetic sex assignment revealed twice as many males as females, although results indicated a conservative bias towards male assignment due to the limited number of X\u2010linked markers available in degraded samples. Our results demonstrate that genome\u2010wide targeted approaches can be effectively applied to highly processed shark fin products to infer population sources and sex composition. This study provides proof\u2010of\u2010concept for integrating genomics into shark trade monitoring, highlighting its potential to improve traceability, support CITES implementation and inform conservation and fisheries management, particularly for species with well\u2010resolved population structure.\n                  <\/jats:p>","DOI":"10.1111\/mec.70546","type":"journal-article","created":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T04:31:32Z","timestamp":1789619492000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Genomic Tracking of Market\u2010Derived Bull Shark Fins Back to Source Population of Origin"],"prefix":"10.1111","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6757-2949","authenticated-orcid":false,"given":"Floriaan","family":"Devloo\u2010Delva","sequence":"first","affiliation":[{"name":"Australian National Fish Collection, NCMI CSIRO  Hobart Tasmania Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8492-5382","authenticated-orcid":false,"given":"Pierre","family":"Feutry","sequence":"additional","affiliation":[{"name":"Environment CSIRO  Hobart Tasmania Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1867-2553","authenticated-orcid":false,"given":"Stanley Kwok Ho","family":"Shea","sequence":"additional","affiliation":[{"name":"Bloom Association, Central  Hong Kong S.A.R China"},{"name":"The ADM Capital Foundation Ltd  Hong Kong S.A.R China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1981-5085","authenticated-orcid":false,"given":"Huarong","family":"Zhang","sequence":"additional","affiliation":[{"name":"Kadoorie Farm and Botanic Garden  Hong Kong, S.A.R China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0402-7564","authenticated-orcid":false,"given":"Laura","family":"Garc\u00eda Barcia","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences Florida International University  North Miami Florida USA"},{"name":"Lilly Research Laboratories Eli Lilly and Company  Indianapolis Indiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9414-7385","authenticated-orcid":false,"given":"Diego","family":"Carde\u00f1osa","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences Florida International University  North Miami Florida USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7976-0947","authenticated-orcid":false,"given":"Demian D.","family":"Chapman","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences Florida International University  North Miami Florida USA"},{"name":"Sharks and Rays Conservation Research Program Mote Marine Laboratory &amp;
