Population structure of the seabob shrimp Xiphopenaeus kroyeri (Heller, 1862) (Crustacea: Penaeoidea) in the littoral of São Paulo, Brazil
TLDR
The species showed an important variation from the typical life cycle that it is assumed to hold over its entire range and should be classified as having a life cycle different from that proposed previously in the literature, i.e. the juveniles prefer inshore areas instead of estuaries. Expand
REPRODUCTION OF THE SPECKLED SWIMMING CRAB ARENAEUS CRIBRARIUS (BRACHYURA: PORTUNIDAE) ON THE BRAZILIAN COAST NEAR 23°30′S
TLDR
1% of all adult females from Ubatuba, São Paulo State, Brazil, were premolt, which indicated the occurrence of another mature instar and thus the absence of a well-defined terminal molt after puberty. Expand
BRACHYURAN COMMUNITY IN UBATUBA BAY, NORTHERN COAST OF SAO PAULO STATE, BRAZIL
TLDR
A brachyuran crab assemblage from eight transects at a non-consolidated sublittoral site in Ubatuba Bay was studied on a monthly basis from September 1995 to August 1996 and the family Majidae was represented by 13 species. Expand
Relative Growth of the Speckled Swimming Crab Arenaeus Cribrarius (Lamarck, 1818) (Brachyura, Portunidae), Near Ubatuba, State of São Paulo, Brazil
TLDR
The majority of relationships showed that the major chela of the males grew in positive allometry, however, the greatest allometric difference between the phases was observed towards the propodus length with 1.09 as juvenile and 1.26 as adult "b"values. Expand
Sexual Maturity of the Speckled Swimming Crab Arenaeus Cribrarius (Lamarck, 1818) (Decapoda, Brachyura, Portunidae), in the Ubatuba Littoral, São Paulo State, Brazil
TLDR
Differences between allometric and gonadal estimates indicate the importance of considering both methods and a comparison of the present results with other available data in portunid crabs is provided. Expand

Abundance and Ecological Distribution of the "Sete-Barbas" Shrimp Xiphopenaeus kroyeri (Heller, 1862) (Decapoda: Penaeoidea) in Three Bays of the Ubatuba Region, Southeastern Brazil
Recommended Citation Costa, R. C., A. Fransozo, F. A. Freire and A. L. Castilho. 2007. Abundance and Ecological Distribution of the "Sete-Barbas" Shrimp Xiphopenaeus kroyeri (Heller, 1862) (Decapoda:Expand
Characterization of the physical and chemical parameters of Ubatuba Bay, Northern Coast of São Paulo State, Brazil
The objective of the present study is to characterize the physical and chemical environmental parameters of Ubatuba Bay (SP), as a subsidy for studies of the composition and distribution of benthicExpand
Reproduction and recruitment of the South American red shrimp, Pleoticus muelleri (Crustacea: Solenoceridae), from the southeastern coast of Brazil
TLDR
Investigation of reproduction, recruitment, and size at sexual maturity of the shrimp P. muelleri off the coast of the state of São Paulo, Brazil, suggest that the main reproductive months extend from late spring to early summer, and the hypothesis of the intrusion of the South Atlantic Central Water mass suggests that this species has a continuous reproductive pattern.
