Among the 201 individuals captured, 98 were females (74.5 – 227 cm TL) and 103 were males (72 – 242 cm TL) with a sexual proportion males to females of 1:1. Females were categorized as immature (N = 78; 74.5 – 170 cm TL), matures (N = 13; 165 – 223 cm TL), pré-ovulatory (N = 2; 181 – 187 cm CT) and pregnant (N = 5; 169 – 227 cm TL). The uterine fecundity ranged from 1 to 10 embryos. The cycle of pregnancy is annual with birth occurring at the end / beginning of the year. The size at first maturity of females was estimated at 170 cm TL. Of the 103 males captured, 75 were immature (72 to 160 cm TL), 8 maturing (170 - 196) and 20 were mature (160 - 242 cm TL). The size of sexual maturity was between 160 and 170 cm. / No período de dezembro de 2003 a dezembro de 2009, foram coletados os aparelhos reprodutores de 201 espécimes de Carcharhinus longimanus, capturados por meio de barcos da frota comercial atuneira, que realizaram pescarias com espinhel pelágico e linha de mão, na área localizada entre as latitudes 06º45’N e 23º36’S e as longitudes de 018º44’W e 053º13’W. Deste total, 98 eram fêmeas (74,5 a 170 cm CT), maduras (N= 13; 165 a 223 cm CT), pré-ovulatórias (N= 2; 181 e 187 cm CT) e prenhes (N= 5; 169 a 227 cm CT). A fecundidade ovariana variou de 1 a 10 folículos vitelogênicos e a uterina, de 1 a 10 embriões. O ciclo de gestação é anual com nascimento ocorrendo ao final/início do ano. O tamanho de primeira maturação das fêmeas desta espécie é de 170 cm CT. Dos 103 machos capturados, 75 eram imaturos (72 – 160 cm CT), 8 em maturação (170 - 196) e 20 eram maduros (160 – 242 cm CT). O tamanho de primeira maturação sexual entre 160 e 170 cm.
