ABSTRACT
We conducted expeditions (N=16) to the Rocas Atoll Biological Reserve aiming study the lemon shark (Negaprion brevirostris) population. Young lemon sharks (N=239) were captured, without mortality, using drift gill nets. The frequency of occurrence was higher for males (N=127) than females (N=112) 1.0♂:0.9♀. Upon capture, sharks were sexed, measured (fork length, total length, and interdorsal length), and released alive. A subset of 73 young lemon sharks received an identification tag before being released. Recaptured females and males showed an increase in total length of 12.7 cm/ year and 12.4 cm/ year, respectively.

Keywords: lemon shark, Negaprion brevirostris, juveniles, population structure, growth, Atol das Rocas.

RESUMO
Foram realizadas 16 expedições à Reserva Biológica do Atol das Rocas para o estudo populacional dos tubarões-limão (Negaprion brevirostris) juvenis. Um total de 239 indivíduos foram capturados utilizando-se rede de arrasto. A proporção sexual entre os tubarões capturados foi 1.0♂:0.9♀, com 127 machos e 112 fêmeas. Quando capturados, os tubarões eram sexados, mensurados (comprimentos furcal, total e interdorsal) e libertados com vida. Um subgrupo de 73 espécimes foram marcados e libertados. Machos e fêmeas recapturados demonstraram um aumento no comprimento de 12.7 cm/ano e 12.4 cm/ano, respectivamente.

Palavras-chave: tubarão-limão, Negaprion brevirostris, juvenis, estrutura populacional, crescimento, Atol das Rocas.
