In fact, at least 90% of elasmobranch species are listed in the International Union for Conservation of Nature (IUCN) Red List, while more than 40% are data-deficient. Although these vertebrates are mainly affected by unsustainable fishery activities, bycatch is also one of the major threats to sharks and batoids worldwide, and represents a challenge for both sustainable fishery management and for biodiversity and conservational efforts. Thus, in this study, DNA barcode methodology was used to identify the bycatch composition of batoid species from small-scale industrial fisheries in the southwest Atlantic and artisanal fisheries from southeast Brazil. A total of 228 individuals belonging to four Chondrichthyes orders, seven families, and at least 17 distinct batoid species were sequenced; among these individuals, 131 belonged to species protected in Brazil, 101 to globally threatened species, and some to species with trade restrictions provided by Appendix II of the Convention on International Trade in Endangered Species (CITES). These results highlight the impacts on marine biodiversity of bycatch by small-scale industrial and unmanaged artisanal fisheries from the southwest Atlantic, and support the implementation of DNA-based methodologies for species-specific identification in data-poor fisheries as a powerful tool for improving the quality of fisheries\u2019 catch statistics and for keeping precise bycatch records.<\/jats:p>","DOI":"10.3390\/genes10040304","type":"journal-article","created":{"date-parts":[[2019,4,18]],"date-time":"2019-04-18T11:58:21Z","timestamp":1555588701000},"page":"304","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["DNA Barcode Reveals the Bycatch of Endangered Batoids Species in the Southwest Atlantic: Implications for Sustainable Fisheries Management and Conservation Efforts"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3108-9867","authenticated-orcid":false,"given":"Bruno Lopes da Silva","family":"Ferrette","sequence":"first","affiliation":[{"name":"Laborat\u00f3rio de Gen\u00e9tica e Conserva\u00e7\u00e3o, Universidade Santa Cec\u00edlia (UNISANTA), Santos 11045-907, Brazil"},{"name":"Laborat\u00f3rio de Gen\u00e9tica Pesqueira e Conserva\u00e7\u00e3o (GenPesC), Instituto do Mar, Universidade Federal de S\u00e3o Paulo (UNIFESP), Santos 11070-102, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodrigo Rodrigues","family":"Domingues","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Gen\u00e9tica Pesqueira e Conserva\u00e7\u00e3o (GenPesC), Instituto do Mar, Universidade Federal de S\u00e3o Paulo (UNIFESP), Santos 11070-102, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matheus Marcos","family":"Rotundo","sequence":"additional","affiliation":[{"name":"Acervo Zool\u00f3gico, Universidade Santa Cec\u00edlia (UNISANTA), Oswaldo Cruz St. 266, Santos 11045-907, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina Provetti","family":"Miranda","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Gen\u00e9tica Pesqueira e Conserva\u00e7\u00e3o (GenPesC), Instituto do Mar, Universidade Federal de S\u00e3o Paulo (UNIFESP), Santos 11070-102, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ingrid Vasconcellos","family":"Bunholi","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Gen\u00e9tica Pesqueira e Conserva\u00e7\u00e3o (GenPesC), Instituto do Mar, Universidade Federal de S\u00e3o Paulo (UNIFESP), Santos 11070-102, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juliana Beltramin","family":"De Biasi","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Gen\u00e9tica Pesqueira e Conserva\u00e7\u00e3o (GenPesC), Instituto do Mar, Universidade Federal de S\u00e3o Paulo (UNIFESP), Santos 11070-102, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Biologia e Gen\u00e9tica de Peixes (LBGP), Instituto de Bioci\u00eancias de Botucatu (IBB), Universidade Estadual Paulista \u201cJ\u00falio de Mesquita Filho\u201d (UNESP), Botucatu 18618-689, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fausto","family":"Foresti","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Biologia e Gen\u00e9tica de Peixes (LBGP), Instituto de Bioci\u00eancias de Botucatu (IBB), Universidade Estadual Paulista \u201cJ\u00falio de Mesquita Filho\u201d (UNESP), Botucatu 18618-689, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4806-9897","authenticated-orcid":false,"given":"Fernando Fernandes","family":"Mendon\u00e7a","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Gen\u00e9tica Pesqueira e Conserva\u00e7\u00e3o (GenPesC), Instituto do Mar, Universidade Federal de S\u00e3o Paulo (UNIFESP), Santos 11070-102, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Last, P., Naylor, G., S\u00e9ret, B., White, W., de Carvalho, M., and Stehmann, M.
