A total of 234 specimens were collected as bycatch during pelagic longline fisheries targeting tunas and swordfish, between December 2003 and December 2010. The fishing area was located between latitudes 10N and 35S and longitudes 3E and 40W. Of the 234 individuals sampled, 118 were females (with sizes ranging from 81 to 227 cm TL, total length) and 116 males (ranging from 80 to 242 cm TL). The reproductive stages of the females were classed as immature, mature, preovulatory and pregnant, while males were divided into immature, maturing and mature. The size at maturity for females was estimated at 170.0 cm TL, while that for males was between 170.0 and 190.0 cm TL. Ovarian fecundity ranged from 1 to 10 follicles and uterine fecundity from 1 to 10 embryos. The reproductive cycle of this species is most likely biennial, with parturition occurring once every two years.<\/jats:p>","DOI":"10.1590\/s1679-87592013000200008","type":"journal-article","created":{"date-parts":[[2013,7,17]],"date-time":"2013-07-17T11:11:28Z","timestamp":1374059488000},"page":"161-168","source":"Crossref","is-referenced-by-count":11,"title":["Reproductive aspects of the oceanic whitetip shark, Carcharhinus longimanus (Elasmobranchii: Carcharhinidae), in the equatorial and southwestern Atlantic Ocean"],"prefix":"10.1590","volume":"61","author":[{"given":"Mirna Regina dos Santos","family":"Tambourgi","sequence":"first","affiliation":[{"name":"Universidade Federal Rural de Pernambuco, Brasil"}]},{"given":"F\u00e1bio H.V.","family":"Hazin","sequence":"additional","affiliation":[{"name":"Universidade Federal Rural de Pernambuco, Brasil"}]},{"given":"Paulo G.V.","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Universidade Federal Rural de Pernambuco, Brasil"}]},{"given":"Rui","family":"Coelho","sequence":"additional","affiliation":[{"name":"University of Florida, USA; Universidade do Algarve, Portugal"}]},{"given":"George","family":"Burgess","sequence":"additional","affiliation":[{"name":"University of Florida, USA"}]},{"given":"Pollyana C.
