Bioecologia do Caranguejo-Uçá Ucides cordatus (Linnaeus) no Complexo Estuarino Lagunar Mundáu/Manguaba (CELMM), Alagoas, Brasil

Abstract: Ucides cordatus (Linnaeus, 1763) (Brachyura, Ocypodoidea, Ucididae), conhecido como caranguejo-uçá, habita tocas no sedimento do manguezal, sendo bastante apreciado na culinária e na confecção de souvenir. Apesar de sua importância, os estudos sobre sua biologia e pesca no Nordeste continuam escassos. O objetivo deste trabalho foi estudar a bioecologia de U. cordatus, no Complexo Estuarino-Lagunar Mundaú/Manguaba (CELMM), Alagoas, Nordeste do Brasil, abordando aspectos morfométricos e crescimento relativo, est… Show more

“…Registries were obtained monthly during the study and clustered according two biological periods (reproductive: January to May; and non-reproductive: June to December). These biological periods were following results previously reported by Araújo and Calado (2008) to Alagoas state, but valid to all northeast Brazilian region (see review by Ibama, 2011). The sex ratio was also calculated for each biological period, and the sexual proportion was compared using the chisquare test (Sokal and Rohlf, 2003).…”

“…Therefore, sex ratio data must always be carefully evaluated; the number of U. cordatus males (i.e., four times higher than that of females) certainly cannot be explained by differential fishery activity because only U. cordatus males are fishing targets in northern and northeast Brazilian regions (Capistrano and Lopes, 2012). Indeed, a review of the overall sex ratio of 'uçá'-crabs reveals discordant patterns, including: 1) a predominance of males reported by Wunderlich and Pinheiro (2013) in Iguape (São Paulo), 2) a predominance of females reported by Góes et al (2010) at Vitória Bay (Espírito Santo), and 3) a gender balance reported by Araújo and Calado (2008) in the Estuarine Lagoon Complex of Mundaú-Manguaba at Maceió (Alagoas). Wunderlich and Pinheiro (2013) conduct studies in a pristine and underexplored mangrove area finding a sex ratio dependence of the arboreal composition and tidal flooding level.…”

“…Conhecido popularmente como caranguejouçá, pode atingir grande porte, sendo explorado em várias regiões brasileiras, onde serve como fonte de alimento e renda para populações ribeirinhas (RODRIGUES et al, 2000;PASSOS & DI BENEDITO, 2005;JANKOWSKY et al, 2006). Apesar de sua importância sócio-econômica, só recentemente tem-se notado um incremento das investigações sobre sua bioecologia (BRANCO, 1993;BOTELHO et al, 1999;IVO et al, 1999IVO et al, , 2000PINHEIRO & FISCARELLI, 2001;ALVES & NISHIDA, 2004;MONTEIRO & COELHO-FILHO, 2004;DIELE et al, 2005;PINHEIRO & HATTORI, 2006;ANDRADE et al, 2007;WUNDERLICH et al, 2008;ARAÚJO & CALADO, 2009), como também por aspectos sociais, econômicos, culturais e ecológicos relacionados a sua pesca (MANESCHY, 1993;NORDI, 1994;FISCARELLI & PINHEIRO, 2002;SOUTO, 2007). Com relação à determinação do tamanho da maturidade sexual que tenha levado em consideração tanto a maturidade morfológica como a fisiológica, somente um estudo foi desenvolvido por PINHEIRO & FISCARELLI (2001) até a presente data, mas para uma população do litoral de São Paulo.…”

“…The same burrows opened by Araújo;Calado (2008) for U. cordatus population studies had their architectures drawn. In that study, the samplings were accomplished through the 'braceamento' technique, where a fisherman introduces his arm in the burrow of the crab until he finds the animal, which is manually removed.…”
