With high exploitation rates, its stock(s) is(are) currently deemed fully exploited or overexploited. While basic ecological information, such as length at first maturity, exists, knowledge of its population structure is limited. A sub-sample of 90 sagittal otoliths of U. cirrata juveniles (300\u2013411 mm total length) collected during the Program for Assessment of the Sustainable Potential of Living Resources in the Exclusive Economic Zone (REVIZEE) in 2001\/2002 was analyzed. Samples came from the outer continental shelf and upper slope of the southeast-south Brazilian coast, divided into three regions: northern (Cabo S\u00e3o Tom\u00e9 to S\u00e3o Sebasti\u00e3o), central (S\u00e3o Sebasti\u00e3o to Cabo Santa Marta Grande), and southern (Cabo Santa Marta Grande to Chu\u00ed). Otolith shape (elliptic Fourier descriptors) and elemental (element:Ca) signatures were examined using univariate (ANOVA, Tukey) and multivariate (MANOVA, LDFA) statistical methods. An overall reclassification success rate of 86% was achieved using both signatures. However, individuals from the three regions were not fully separable, indicating a single, albeit not homogeneous, population unit for fisheries management. As fish stocks are dynamic, contemporary studies should be conducted to verify whether this population structure persists.<\/jats:p>","DOI":"10.3390\/fishes10020063","type":"journal-article","created":{"date-parts":[[2025,2,4]],"date-time":"2025-02-04T07:41:44Z","timestamp":1738654904000},"page":"63","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Stock Structure of the Gulf Hake Urophycis cirrata (Teleostei: Phycidae) in South-Western Atlantic Using Otolith Shape and Elemental Analyses"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2197-6187","authenticated-orcid":false,"given":"C\u00e9sar","family":"Santificetur","sequence":"first","affiliation":[{"name":"Laborat\u00f3rio de Diversidade, Ecolog\u00eda e Evolu\u00e7\u00e3o de Peixes\u2014DEEP Lab, Instituto Oceanogr\u00e1fico da Universidade de S\u00e3o Paulo (IOUSP), Pra\u00e7a do Oceanogr\u00e1fico 191, S\u00e3o Paulo 05508-120, Brazil"},{"name":"Centro Interdisciplinar de Investiga\u00e7\u00e3o Marinha e Ambiental (CIIMAR), Avenida General Norton de Matos SN, 4550-208 Matosinhos, Portugal"}]},{"given":"Carmen L\u00facia Del Bianco","family":"Rossi-Wongtschowski","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Diversidade, Ecolog\u00eda e Evolu\u00e7\u00e3o de Peixes\u2014DEEP Lab, Instituto Oceanogr\u00e1fico da Universidade de S\u00e3o Paulo (IOUSP), Pra\u00e7a do Oceanogr\u00e1fico 191, S\u00e3o Paulo 05508-120, Brazil"}]},{"given":"Andr\u00e9","family":"Ruperti","sequence":"additional","affiliation":[{"name":"Centro Interdisciplinar de Investiga\u00e7\u00e3o Marinha e Ambiental (CIIMAR), Avenida General Norton de Matos SN, 4550-208 Matosinhos, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1297-3198","authenticated-orcid":false,"given":"Agostinho","family":"Almeida","sequence":"additional","affiliation":[{"name":"REQUIMTE\/LAQV, Laborat\u00f3rio de Qu\u00edmica Aplicada, Faculdade de Farm\u00e1cia da Universidade do Porto (FFUP), Rua Jorge Viterbo Ferreira 228, 4050-313 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8021-4783","authenticated-orcid":false,"given":"Edgar","family":"Pinto","sequence":"additional","affiliation":[{"name":"REQUIMTE\/LAQV, Escola Superior de Sa\u00fade, Instituto Polit\u00e9cnico do Porto, Rua Dr. Ant\u00f3nio Bernardino de Almeida 400, 4200-072 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2831-025X","authenticated-orcid":false,"given":"Alberto Teodorico","family":"Correia","sequence":"additional","affiliation":[{"name":"Centro Interdisciplinar de Investiga\u00e7\u00e3o Marinha e Ambiental (CIIMAR), Avenida General Norton de Matos SN, 4550-208 Matosinhos, Portugal"},{"name":"Departamento de Produ\u00e7\u00e3o Aqu\u00e1tica, Instituto de Ci\u00eancias Biom\u00e9dicas Abel Salazar da Universidade do Porto (ICBAS-UP), Rua Jorge Viterbo Ferreira 228, 4050-313 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,4]]},"reference":[{"key":"ref_1","unstructured":"Cohen, D.M., Inada, T., Iwamoto, T., and Scialabba, N.
