(Sociedade Brasileira de Zoologia, 2014-08-01)
Trawl fisheries are associated with catches of swimming crabs, which are an important economic resource for commercial as well for small-scale fisheries. This study evaluated the population biology and distribution of the ...
Comparison of cheliped weight and growth in two species of crabs of the genus Callinectes (Brachyura, Portunidae)
(Inst Tecnologia Parana, 1998-01-01)
A comparison of the cheliped's weight in two species of the genus Callinectes was accomplished. The species C. danae e C. ornatus were collected by two otter trawl in Ubatuba bay (23 degrees 26' S and 45 degrees 02' W). ...

Regulation by the exogenous polyamine spermidine of Na,K-ATPase activity from the gills of the euryhaline swimming crab Callinectes danae (Brachyura, Portunidae)
(ELSEVIER SCIENCE INC, 2008)
Euryhaline crustaceans rarely hyporegulates and employ the driving force of the Na,K-ATPase, located at the basal surface of the gill epithelium, to maintain their hemolymph osmolality within a range compatible with cell ...
