SPATIAL AND SEASONAL DISTRIBUTIONS OF CALLINECTES DANAE (DECAPODA, PORTUNIDAE) IN UBATUBA BAY, SÃO PAULO, BRAZIL [PDF]
Journal of Crustacean Biology, 2001 The spatial and seasonal distributions of Callinectes danae Smith, 1869, in Ubatuba Bay, Sao Paulo, Brazil, were investigated as a part of a broad study on the general biology of portunids along the northern coast of Sao Paulo State, Brazil. Swimming crabs were collected during one year, from September 1995 to August 1996, along eight transects ...

Contractions induced by sodium withdrawal in crab (Callinectes danae) muscle fibres.
Journal of Physiology, 1983 A study was made of the effects of Na removal on the resting tension of single muscle fibres of the crab Callinectes danae. Reduction of [Na]o (replacement with Li, Tris or choline) below a threshold value, typical for each fibre, induced spontaneous, local contractions randomly dispersed along the fibres; this was followed by propagated contractile ...

INFESTATION BY OCTOLASMIS LOWEI (CIRRIPEDIA: POECILASMATIDAE) IN CALLINECTES DANAE AND CALLINECTES ORNATUS (DECAPODA: PORTUNIDAE) FROM SÃO SEBASTIÃO, BRAZIL [PDF]
Journal of Crustacean Biology, 2002 Abstract Two species of blue crabs were investigated with regard to infestation of the branchial chambers by the pedunculate cirriped Octolasmis lowei. In Callinectes danae, the frequency of infestation was 22.4%, and the mean intensity of infestation was 2.2 ± 0.2 (range: 1–8).

Bulletin of Environmental Contamination and Toxicology, 2020 This short note aims to report in detail a preliminary assessment of the concentrations of Cd, Hg and Pb in tissues of blue crabs Callinectes danae collected from the Cananéia-Iguape-Peruíbe estuarine complex (CIP), in the South of São Paulo State coast, Brazil. In October 2014, blue crabs were collected from CIP. Tissues were removed by dissection and

Ovarian development stages of Callinectes danae and Callinectes ornatus (Brachyura, Portunidae)
Crustaceana, 2009Along the Brazilian coast, Callinectes danae and Callinectes ornatus are very important species, both commercially and ecologically. The fishing pressure and the social and economic importance of the group justify the need for specific detailed information concerning the reproduction of each representative for the development of management actions ...

Kinetics of glycogen phosphorylase a from the muscle of the blue crab, Callinectes danae
Archives of Biochemistry and Biophysics, 1974Abstract The kinetics of purified glycogen phosphorylase a from the muscle of the blue crab ( Callinectes danae ) were studied in the direction of glycogen synthesis, and in the direction of glycogen degradation with P i or arsenate as substrates. The effects of AMP, UDPG, G-6- P , glucose, and arsenate on the appropriate systems were studied. AMP
