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 |
