Abstracts

The present study sought to study the reproductive biology of the oceanic whitetip shark, Carcharhinus longimanus, in the equatorial and southwestern Atlantic Ocean. 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.

O presente trabalho tem como objetivo estudar a biologia reprodutiva do tubarão galha-branca, Carcharhinus longimanus, para assim ampliar as informações sobre a espécie. A área de estudo compreendeu o Atlântico Sudoeste e Equatorial e foram utilizados 234 espécimes coletados entre dezembro de 2003 e dezembro de 2010. Estes foram obtidos por redes de pesca comercial de atum e peixe-espada e vários tubarões, incluindo o tubarão galha-branca, são capturados nesta pescaria de forma acidental. Esses espinhéis operam no Atlântico Sudoeste e Equatorial entre as latitudes 10N e 35S, e longitudes 3E e 40W. Entre os 234 indivíduos capturados, 118 foram fêmeas (81 a 227cm de comprimento total, CT) e 116 foram machos (80 a 242 cm CT). Os estados de maturação das fêmeas foram categorizados como: imaturas, maduras, pré-ovulatórias e grávidas. Os machos foram divididos em: imaturos, em maturação e maduros. O tamanho da primeira maturação para as fêmeas foi estimado em 170 cm de CT, enquanto que o tamanho de maturação sexual dos machos variou entre 170 e 190 cm de CT. A fecundidade ovariana oscilou entre um e 10 folículos, enquanto que a fecundidade do útero oscilou entre um e 10 embriões. Os dados indicam que o ciclo reprodutivo é provavelmente bianual, com o nascimento ocorrendo uma vez a cada dois anos.
