“…Most studies on decapod crustaceans from the coast of Pará refer to subtidal areas (e.g., Corrêa and Martinelli 2009, Nevis et al 2009, Bentes et al 2011, Oliveira et al 2012, Silva and MartinelliLemos 2012, Cavalcante et al 2012. Most published works related to intertidal areas of the coast of Pará were focused on ichthyofauna (e.g., Krumme 2007, 2009) and benthos (e.g., Rosa Filho et al 2006).…”

The present work investigated the occupation and the correlation of the shrimp abundance in relation to environmental variables in different habitats (mangroves, salt marshes and rocky outcrops) in an Amazon estuary Farfantepenaeus subtilis (98.36%) (marine) followed by Alpheus pontederiae (0.76%) (estuarine), Macrobrachium surinamicum (0.45%) and Macrobrachium amazonicum (0.43%) predominantly freshwater. The species F. subtilis and A. pontederiae occurred in the three habitats, whereas M. surinamicum occurred in salt marsh and rocky outcrop and M. amazonicum only in marisma. Temperature and pH were the most important environmental descriptors that significantly affected the density and biomass of shrimps.

“…In this study we found that C. danae is most abundant in sites where sediment grain is finer, particularly silt and clay, which may be due to the larger amount of organic matter available in this type of sediment (Melo 1996;Teixeira & Sá 1998;Nevis et al 2009). The preference for regions with thinner sediment may be associated with the need to search for food, because when a larger amount of organic matter is available there is an increase in the number of organisms that feed on it, including C. danae (Mantelatto 2000).…”

Environmental factors modulating the abundance and distribution of Callinectes danae (Decapoda: Portunidae) from two areas of the southeastern coast of Brazil

Abstract:The distribution and abundance of marine organisms are directly or indirectly a function of biotic and abiotic features such as sediment and water properties. In this study we analyzed the spatial and temporal distribution of Callinectes danae in two distinct littoral areas of the northern coast of the State of São Paulo, Brazil and associated them with local geomorphologic features and environmental factors. We collected specimens on a monthly basis, from July 2001 to June 2003, using a fishing boat equipped with double-rig net, in two locations: Ubatuba (UBA) and Caraguatatuba (CAR). Collecting was carried out in seven transects with different depths, which were further subdivided into two regions: bay region (5, 10, 15 and 20 m deep); and inner shelf region (25, 30 and 35 m deep). Samples from different periods and transects differed significantly in abundance. A positive correlation was found between the abundance of C. danae and the following parameters: temperature at the bottom, organic matter content and Phi (grain diameter). By contrast, a negative correlation was established between specimen abundance and salinity at the bottom. The total abundance was highest in 5 m deep transects in both regions. Summer was the season when individuals were least abundant in both areas. We concluded that the spatial and temporal distribution of C. danae are determined by a set of environmental factors and not just by one single factor.

“…Os fatores ambientais, no estuário do Caeté, mantiveram um padrão semelhante ao registrado em pesquisas anteriores na região costeira do nordeste paraense (Nevis et al, 2009;Magalhães et al, 2009;Pinto-Marques, 2009;Costa et al, 2011;Pinheiro et al, 2011;Oliveira et al, 2012;Oliveira et al, 2013), com temperatura praticamente constante ao longo do ano, e salinidade com grandes variações. A variação da salinidade ocorre em consequência da diminuição ou aumento da pluviosidade, determinando duas estações climáticas: seca e chuvosa.…”

The life cycle of these species includes only two zoeal stages, which are distinctive by their very elongate rostral and posterolateral carapace spines, and are commonly found in estuarine meroplanktonic samples. The present study provides information about the abundance of porcellanid larvae at an estuarine system in the Amazon coastal zone, aiming to understand their distribution in relation to some physicochemical variables: seasonal, diel, tidal and lunar cycles, temperature and salinity. Samples were collected monthly from April 2000 to April 2001 with a plankton conical net with 300μm of mesh size, by horizontal hauls, in the Caeté River estuary, Pará, Brazil. Only zoeal stages of porcellanid larvae were found. In general, their abundance was greater in dry season (8.08±11.43 larvae.m -3 ) in relation to rainy season (0.99±3.13 larvae.m -3 ), and flood tide (7.52±11.40 larvae.m -3 ) in relation to ebb tide (1.11±2.14 larvae.m -3 ). Greater densities were also registered at higher degrees of salinity. The other variables, moon phases, diel cycle and temperature, had not a significant influence on porcellanid larval abundance in the Caeté River estuary.
