- Population Structure and Growth of Young Lemon Shark, Negaprion brevirostris (Poey, 1868), at the Atol das Rocas Biological Reserve, Brazil Paulo G. V. Oliveira Diogo Silva de Oliveira Patrícia Barros Pinheiro Fábio H. V. Hazin Felipe C. Carvalho Dráusio P. Veras Maurizélia B. Silva Ciencias de la Tierra growth juveniles Lemon shark Atol das Rocas population structure 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. 2011 artículo científico 1646-8872 https://www.redalyc.org/articulo.oa?id=388340135002 en http://www.redalyc.org/revista.oa?id=3883 Revista de Gestão Costeira Integrada - Journal of Integrated Coastal Zone Management application/pdf Associação Portuguesa dos Recursos Hídricos Revista de Gestão Costeira Integrada - Journal of Integrated Coastal Zone Management (Portugal) Num.4 Vol.11
