“…In our study there was a positive correlation between the abundance and phi (sediment texture) and organic matter content, corroborating the findings in close areas, as made by Mantelatto et al (1995a) in Fortaleza Bay, where H. pudibundus was also more abundant in regions with higher organic matter content. On the other hand, Lima et al (2014a) found no significant relationship, probably because their sampling was restricted to depths of 20 m or less. Nonetheless, they found the higher number of individuals in Mar Virado Bay, in which the silt and clay fraction predominates.…”

“…Characteristics such as sediment texture and organic matter content, and water temperature and salinity, are important factors regulating the distribution and ecological relationships of benthic organisms, including decapod crustaceans. These factors control local marine productivity and environmental conditions, which in turn determine species' occurrence (Buchanan & Stoner 1988, Lima et al 2014a, Andrade et al 2015.…”

“…Although H. pudibundus is an important species in the food webs of unconsolidated sediments along the infralittoral (Mantelatto & Petracco 1997), most previous studies focused on biological aspects, including larval and juvenile development in the laboratory and from field samplings (Rieger & Hebling 1993, Hebling & Rieger 2003, Negreiros-Fransozo et al 2008, population structure (Mantelatto et al 1995b, Fracasso & Branco 2005, Klôh & Di Beneditto 2010, Lima et al 2014a, morphometry , 1994, feeding strategies (Mantelatto & Petracco 1997), reproductive biology (Reigada & Negreiros-Fransozo 1999, Lima et al 2014b, and growth and mortality (Keunecke et al 2007). A few studies focused on H. pudibundus distribution (Mantelatto et al 1995a, Lima et al 2014a, but none of them included areas of 20 m in depth or deeper.…”

This study evaluated the relationships between environmental factors and the spatio-temporal distribution of H. pudibundus, with the hypothesis of differential occupation in coastal areas of southeastern Brazil. The samplings took place monthly in January-December 2000 period, along nine transects from 2 to 40 m of depth, in Ubatuba region, northern coast of São Paulo. We collected 1808 individuals of H. pudibundus. The highest abundance was recorded in winter in the transects 10-25 m deep. Abundance was positively correlated with organic matter content and texture sediment (phi values). With the retreat of the South Atlantic Central Water (SACW) in autumn and winter, the sediment swirls, suspending the detritivore and filter-feeding macrofauna, increasing the food availability. Sites characterized by finer sediment offer higher food availability, besides facilitating H. pudibundus burying behavior. Due to its opportunistic predatory behavior, this species feeds on a variety of organisms, including mollusks, annelids and foraminifera, which are preys more abundant in the studied area and in sediments of finer grain size.

“…Six transects were established in each bay, at 5, 10, 15, and 20 m (parallel to the beach line), as well as one transect in an area sheltered from wave action (7.5 m depth), and another in a more exposed area (10 m depth) (Figure 1). Environmental features of bays and transects were characterized by Bertini et al (2010) and Lima et al (2014). A shrimp fishing boat equipped with double-rig nets (mesh size 20 mm and 15 mm in the cod end) was used for sampling.…”

Reproductive features of the swimming crab Callinectes danae(Crustacea, Portunoidea) on the subtropical coast of Brazil: a sampling outside the estuary

The life cycle of the crab Callinectes danae is estuarine-dependent, and studies on aspects of their biology should also cover marine areas. The present study investigated the sexual maturity, as well as habitat preference by adults in different gonadal stages, and the crabs' reproductive periodicity outside the estuary. Three bays on the subtropical southeastern coast of Brazil were sampled monthly for two years. For each bay, six transects were established, four of them parallel to the beach line (5, 10, 15 and 20 m depth), as well as one transect in an exposed area, and another sheltered from the action of waves. The results showed that the pattern of spatio-temporal distribution of adults C. danae was similar in three bays, although the highest abundance was found in Ubatumirim. Females with developed gonads/ovigerous females were found in greater abundance than females with rudimentary/developing gonads, mainly in deeper transects. Although the areas sampled have different environmental characteristics, the reproductive pattern of the species did not change, showing continuous reproduction throughout, with more abundance of reproductive females on spring and summer. Males reached maturity at larger sizes than females in all three bays.Keywords: blue crab, change in habitat use, reproductive activity, sexual maturity.Características reprodutivas do siri Callinectes danae (Crustacea, Portunoidea) na região subtropical da costa do Brasil: uma amostragem fora do estuário ResumoO siri Callinectes danae é estuarino dependente em seu ciclo de vida, sendo que os estudos que levantam informações sobre os aspectos da sua biologia devem também abranger regiões marinhas. Assim, o presente estudo teve como objetivo investigar a maturidade sexual, bem como a preferência ocupacional por adultos em diferentes estágios gonadais e sua periodicidade reprodutiva fora da região estuarina. Para tanto, três enseadas da porção subtropical do litoral sudeste brasileiro foram amostradas mensalmente, durante dois anos. Para cada enseada, seis transectos foram estabelecidos, quatro deles paralelos à linha de praia (5, 10, 15 e 20m de profundidade), um transecto exposto e outro abrigado à ação de ondas. Os resultados mostraram que o padrão de distribuição espaço-temporal de adultos de C. danae foi similar nas três enseadas, embora uma maior abundância tenha sido encontrada em Ubatumirim. Fêmeas ovígeras e com gônadas desenvolvidas foram encontradas em maior abundância que fêmeas com gônadas rudimentares e em desenvolvimento, principalmente nos transectos mais profundos. Apesar das regiões amostradas possuírem características ambientais diferenciadas, o padrão reprodutivo da espécie não sofreu alterações, apresentando reprodução contínua, com maior abundância de fêmeas reprodutivas na primavera e verão. Machos atingiram maturidade em tamanhos maiores que as fêmeas nas três enseadas.Palavras-chave: siri azul, alterações na ocupação do hábitat, atividade reprodutiva, maturidade sexual.

“…Population studies often evaluate density, age/size composition, sex ratio, juvenile recruitment rate, size at onset of sexual maturity, and reproductive period (Colpo and Negreiros-Fransozo, 2004;Lima et al, 2014;Andrade et al, 2015;Hirose et al, 2015). The assessment of some of these population parameters can be affected by the sampling procedure chosen for the study (Macia et al, 2001;Johnson, 2003;Costa and Negreiros-Fransozo, 2003;Hirose et al, 2015).…”

We examined how the sampling technique can aff ect the evaluation of Minuca vocator (Herbst, 1804) population structure. We used two sampling procedures: catch-per-unit-eff ort (CPUE) and quadrat technique (QT). Body size, size-frequency distribution, population density, juvenile recruitment rates, proportion of ovigerous females and sex ratio were compared between the sampling procedures. QT allowed us to estimate and compare crab and burrow densities. CPUE sampled both adult crabs and the largest crabs more frequently, whereas QT recorded a greater proportion of smaller crabs. CPUE underestimated the size of M. vocator populations, while density estimates obtained with QT were accurate. Th e proportion of juveniles was higher with QT than with CPUE, suggesting that recruitment rates estimated by QT were more suitable. Th e sampling eff ort provided by CPUE was more effi cient for obtaining ovigerous-dependent information than QT. Both sampling techniques showed a predominance of males in all three M. vocator populations. Th e population density estimation based on burrows overestimated the natural density of M. vocator in all mangroves.
