Abstract The spatial and seasonal distributions of Callinectes danae Smith, 1869, in Ubatuba Bay, São Paulo, Brazil, were investigated as a part of a broad study on the general biology of portunids along the northern coast of São Paulo State, Brazil. Swimming crabs were collected during one year, from September 1995 to August 1996, along eight transects determined according to local physiographic features. Three replicate trawls were performed monthly at each transect. Depth, salinity… Expand
Abundance and distribution of the swimming crab Callinectes danae Smith, 1869 (Crustacea, Decapoda, Portunidae) in the Ubatuba region, southeastern Brazil
TLDR
Based on canonical correspondence analysis, the most relevant environmental factors for the spatio-temporal distribution of C. danae, in addition to salinity, were the bottom-water temperature and the sediment texture. Expand
Environmental factors modulating the abundance and distribution of Callinectes danae (Decapoda: Portunidae) from two areas of the southeastern coast of Brazil
TLDR
It is 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. Expand
ON THE POPULATION STRUCTURE OF Callinectes danae AND Callinectes ornatus (DECAPODA, PORTUNIDAE), IN GUANABARA BAY, RIO DE JANEIRO STATE, BRAZIL
Guanabara Bay forms an estuarine ecosystem that is degraded on account of the action of several contamination sources. Despite this, it maintains an important fishery production that is mostlyExpand
Population structure and temporal variation of the roughneck shrimp Rimapenaeus constrictus (Decapoda: Penaeoidea) in a coastal bay of the Southwestern Atlantic
ABSTRACT Few studies have been performed regarding long-term variation of penaeids in coastal areas, especially of the marine shrimp Rimapenaeus constrictus, which is distributed along the westernExpand
Abundance and ecologic distribution of the shrimp Rimapenaeus constrictus (Crustacea: Penaeidae) on the northern coast of São Paulo State, Brazil
TLDR
Sediment type and temperature are the most important variables affecting the spatial and seasonal distribution of this species, and a more diversified sediment at UBM and UBA apparently favours the establishment of this shrimp in the region. Expand
Reproductive features of the swimming crab Callinectes danae(Crustacea, Portunoidea) on the subtropical coast of Brazil: a sampling outside the estuary.
TLDR
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, and females with developed gonads/ovigerous females were found in greater abundance than females with rudimentary/developing gonads, mainly in deeper transects.

Ecological distribution of the shrimp Nematopalaemon schmitti (Crustacea: Decapoda: Caridea) in three bays on the south-eastern coast of Brazil
TLDR
Observations suggest that water temperature, sediment texture, organic-matter content, and the presence of biodetritus and plant fragments, provided favourable environmental conditions for the establishment of N. schmitti in the region. Expand
Distribution and Population Structure of Callinectes danae (Decapoda: Portunidae) in a Tropical Brazilian Estuary
TLDR
Both the scarcity of males, probably resulting from size-selective catch, and the low proportion of ovigerous females, compared with that observed in other Brazilian estuaries, suggest that the population has been overexploited. Expand
Reproductive migration and population dynamics of the blue crab Callinectes danae in an estuary in southeastern Brazil
TLDR
Investigation of the population dynamics and reproduction of Callinectes danae in the Estuarine–Bay Complex of São Vicente, São Paulo, Brazil, to provide basic biological information for public policies for the management of this fishery showed seasonal-continuous reproduction. Expand
Environmental variables influencing the Callinectes (Crustacea: Brachyura: Portunidae) species distribution in a tropical estuary—Cachoeira River (Bahia, Brazil)
TLDR
The assumption that species distribution patterns of this genus are the result of both variable influence, namely salinity, and complex intraspecific and interspecific relations between the congeneric species is supported. Expand
