One hermaphroditic individual of 95 cm was found. Males were few in numbers and dominated by immature specimens. Female length at first sexual maturity was 98.5 cm. Mean ovarian and uterine fecundity were 13.2 oocytes per female and 9.9 embryos per pregnant female, respectively. Total length of embryos with completely absorbed external yolk sacs ranged between 233 and 300 mm. Sex ratio (F\/M) of embryos with completely absorbed external yolk sac was 0.9. All stages of reproduction were found during the 12-month sampling period. Results were compared with those from other regions. A hypothesis is formulated on the existence of several regional populations based on morphometric and reproductive parameters observed in different areas.<\/jats:p>","DOI":"10.1016\/s1054-3139(03)00146-2","type":"journal-article","created":{"date-parts":[[2003,10,17]],"date-time":"2003-10-17T18:36:21Z","timestamp":1066415781000},"page":"1335-1341","source":"Crossref","is-referenced-by-count":30,"title":["Reproductive biology and embryonic development of Centroscymnus coelolepis in Portuguese mainland waters"],"prefix":"10.1093","volume":"60","author":[{"given":"Ana","family":"Ver\u00edssimo","sequence":"first","affiliation":[{"name":"IPIMAR, Av. de Bras\u00edlia 1449-006 Lisboa, Portugal"}]},{"given":"Leonel","family":"Gordo","sequence":"additional","affiliation":[{"name":"Faculdade de Ci\u00eancias, Universidade de Lisboa, Departamento de Biologia Animal, Instituto de Oceanografia Bloco C2, Campo Grande, 1749-016 Lisboa, Portugal"}]},{"given":"Ivone","family":"Figueiredo","sequence":"additional","affiliation":[{"name":"IPIMAR, Av. de Bras\u00edlia 1449-006 Lisboa, Portugal"}]}],"member":"286","published-online":{"date-parts":[[2003,1,1]]},"reference":[{"key":"2019081306350874900_b1","doi-asserted-by":"crossref","first-page":"1019","DOI":"10.1017\/S0025315401005008","article-title":"Aspects of reproduction of deep water sharks Centroscymnus coelolepis and Centrophorus squamosus from west of Ireland and Scotland","volume":"81","author":"Clarke","year":"2001","journal-title":"Journal of the Marine and Biological Association of the United Kingdom"},{"key":"2019081306350874900_b2","article-title":"Comparisons of trawl and longline catches of deepwaters elasmobranches West and North of Ireland","author":"Clarke","year":"2002"},{"key":"2019081306350874900_b3","article-title":"Segregation of the Mediterranean population of Centroscymnus coelolepis (Chondrichthyes: Squalidae): a description and survey","author":"Cl\u00f2","year":"2002"},{"key":"2019081306350874900_b4","doi-asserted-by":"crossref","first-page":"923","DOI":"10.1017\/S002531549800109X","article-title":"Reproductive biology of two deep-water sharks from the British Isles, Centroscymnus coelolepis and Centrophorus squamosus (Chondrichthyes: Squalidae","volume":"79","author":"Girard","year":"1999","journal-title":"Journal of the Marine Biological Association of the United Kingdom"},{"key":"2019081306350874900_b10","first-page":"97","article-title":"Capture par unit\u00e9 d'effort d'esp\u00e8ces profondes du talus continental \u00e0 l'ouest des \u00edles Britanniques","volume":"24","author":"Girard","year":"2000","journal-title":"Cybium"},{"key":"2019081306350874900_b5","article-title":"Report of the working group on the biology and assessment of deep-sea fisheries resources","author":"ICES","year":"2002"},{"key":"2019081306350874900_b6","first-page":"23","article-title":"Proposal of a maturity stages scale for oviparous and viviparous cartilaginous fishes (Pisces, Chondrichthyes)","volume":"50","author":"Stehmann","year":"2002","journal-title":"Archive of Fishery and Marine Research"},{"key":"2019081306350874900_b7","doi-asserted-by":"crossref","first-page":"476","DOI":"10.1006\/jmsc.2000.0724","article-title":"The effects of fishing on sharks, rays and chimaeras (chondrichthyans), and the implications for marine ecosystems","volume":"57","author":"Stevens","year":"2000","journal-title":"ICES Journal of Marine Sciences"},{"key":"2019081306350874900_b8","doi-asserted-by":"crossref","first-page":"167","DOI":"10.2331\/suisan.54.167","article-title":"Size at maturity, reproductive cycle, fecundity, and depth segregation of the deep sea squaloid sharks Centroscymnus owstoni and C. coelolepis in Suruga Bay, Japan","volume":"54","author":"Yano","year":"1988","journal-title":"Nippon Suisan Gakkaishi"},{"key":"2019081306350874900_b9","volume-title":"Biostatistical Analysis","author":"Zar","year":"1996","edition":"3rd edition"}],"container-title":["ICES Journal of Marine Science"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/icesjms\/article-pdf\/60\/6\/1335\/29157030\/60-6-1335.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,13]],"date-time":"2019-08-13T10:36:49Z","timestamp":1565692609000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/icesjms\/article\/60\/6\/1335\/653948"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,1,1]]},"references-count":10,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2003,1,1]]},"published-print":{"date-parts":[[2003,1,1]]}},"URL":"https:\/\/doi.org\/10.1016\/s1054-3139(03)00146-2","relation":{},"ISSN":["1095-9289","1054-3139"],"issn-type":[{"value":"1095-9289","type":"electronic"},{"value":"1054-3139","type":"print"}],"subject":[],"published-other":{"date-parts":[[2003]]},"published":{"date-parts":[[2003,1,1]]}}}
