“…segments (Pinheiro & Fransozo 1993). In some crustaceans, these morphological changes are essential to attain sexual maturity (Petriella & Boschi 1997;Souza-Carvalho et al 2011) and can be revealed by relative growth analysis (Pinheiro & Hattori 2006;Miranda & Mantelatto 2010). In carcinology, this subject is common with species of Brachyuran infraorder (Hartnoll 2001), but a lag is verified with those for Anomuran infraorder, where only a few articles are available about sexual dimorphism (Biagi & Mantelatto 2006;Miranda & Mantelatto 2010;Ferreira 2015).…”

“…Density-dependent factors, as well as food availability can cause metabolic changes with effects on growth rates, leading to an advance or delay in size at maturity (Wenner et al, 1974;Hines, 1989). Alterations in this variable can also be attributed to the action of different stressors on populations, such as fishing pressure (McQuaid et al, 2006), or result from variations or inaccuracies in the methods employed (Souza-Carvalho et al, 2011).…”

Biología poblacional del cangrejo de manglar Ucides cordatus (Decapoda: Ucididae) en un estuario tropical semiárido. The mangrove crab Ucides cordatus is an important resource of estuarine regions along the Brazilian coast. U. cordatus is distributed from Florida, USA, to the coast of Santa Catarina, Brazil. The species plays an important role in processing leaf litter in the mangroves, which optimizes the processes of energy transfer and nutrient cycling, and is considered a keystone species in the ecosystem. Population declines have been reported in different parts of the Brazilian coast. in the present study we evaluated aspects of the population structure, sex ratio and size at morphological sexual maturity. We analyzed 977 specimens collected monthly over 24 months (2010)(2011)(2012), in a mangrove of the Jaguaribe River, in the municipality of Aracati on the East coast of Ceará state, Northeastern Brazil. The study area has a mild semiarid tropical climate, with mean temperatures between 26 and 28 o C. The area is located within the eco-region of the semiarid Northeast coast, where mangroves occur in small areas and estuaries are affected by mesomareal regimes. The population structure was evaluated by the frequency distribution of size classes in each month, and the overall sex ratio was analyzed using the chi-square test. Size at morphological sexual maturity was estimated based on the allometry of the cheliped of the males and the abdomen width of the females, using the program REGRANS. The size-frequency distribution was unimodal in both sexes. The overall sex ratio (M: F) (1:0.6) was significantly different from 1:1. Analysis of the sex ratio by size class showed that the proportion of males increased significantly from size class 55-60mm upward, and this pattern persisted in the larger size classes. in the smaller size classes the sex ratio did not differ from 1:1. The size at morphological sexual maturity was estimated at a carapace width (CW) of 52mm and 45mm for males and females, respectively. Analysis of the population parameters indicated that the population of U. cordatus in the Jaguaribe River mangrove is stable. However, constant monitoring of the population is required to detect any changes in the population attributes that may affect this stability. Rev. Biol. Trop. 61 (4): 1721-1735. Epub 2013 December 01.Key words: allometry, population structure, fishery management, sex ratio, size at sexual maturity.The study of population biology furthers our understanding of the ecological stability of a species in a particular habitat (Castiglioni et al., 2006). Population parameters of brachyuran crabs have been investigated by analyzing the distribution of individuals in size class, sex ratio, range in size at sexual maturity, reproductive cycle, fecundity, and juvenile recruitment (Thurman, 1985;Díaz & Conde, 1989;Flores & Negreiros-Fransozo, 1999;Conde et al., 2000;Cobo, 2005;Litulo, 2005;Benetti et al., 2007;Bezerra & Mathews-Cascon, 2007;Kassuga et al., 2008;Gregati & Negreiros-Frans...

“…Apesar da semelhança morfológica entre essas duas fases (jovens e adultos), esses crustáceos também podem por fases larvais e pós-larvais (Bolla Jr et al, 2014), e somente após atingir a maturidade sexual é que se tornam adultos. Esse tamanho pode variar entre as espécies, sendo registrado para: C. ornatus a partir de 40,7 mm largura da carapaça (LC) para fêmeas e 43,5 mm LC para machos (Souza-Carvalho et al, 2011); H. pudibundus a partir de 36 mm LC (fêmeas), 35 mm LC (macho) Branco, 2005) e P. punctata 24,9 mm LC para fêmeas e 27,4 mm LC para machos (Almeida et al, 2013).…”

O presente estudo visa identificar as espécies de crustáceos mais comuns pesca de arrasto segundo o conhecimento de pescadores de três municípios do litoral sul do Estado do Espírito Santo, sudeste do Brasil, e apresentar alguns aspectos relacionados à sua biologia. Entre setembro de 2016 e fevereiro de 2017 foram realizadas observações do cotidiano dos pescadores artesanais e entrevistados 92 pescadores. Todos os entrevistados são do sexo masculino, com idade que varia de 18 a 71 anos, baixa escolaridade e atuam na pesca entre 1 e 41 anos. Em Anchieta, as espécies alvo são os camarões sete-barbas, rosa e branco, enquanto que em Piúma e Marataízes apenas o sete-barbas é alvo da pesca. Nestas comunidades, a carcinofauna acompanhante é composta por siris e caranguejos. Segundo os pescadores, esses crustáceos apresentam semelhanças nos estágios juvenil e adulto, com tais fases ocorrendo no mesmo local. Foi descrita por eles os caracteres de dimorfismo sexual desses organismos. As informações obtidas junto às comunidades tradicionais podem contribuir para a conservação das espécies alvo e da fauna acompanhante, uma vez que o conhecimento etnobiológico é equivalente com a literatura. Este saber local pode ser utilizado em propostas de manejo sustentável bem como na diminuição do impacto sobre as populações das espécies alvo e fauna acompanhante.
