IMPROVING PRODUCTION OF SOFT-SHELLED SWIMMING CRABS: MACROSCOPIC SIGNS OF MOLTING AS A TOOL FOR SELECTION AND MANAGEMENT OF Callinectes danae AND Callinectes exasperatus (PORTUNIDAE, DECAPODA, CRUSTACEA) [PDF]
In order to improve the efficiency of soft-shell crab production, we investigated whether it is technically viable to increase harvesting rates of soft-shelled crabs of the species Callinectes danae and C. exasperatus by selecting animals based on macroscopic molt signs and maintaining them in specific facilities.

Callinectes danae Smith, 1869, known as ''siri-azul'', is an important fishery resource along the Brazilian coast. The reproductive cycle of this species was studied based on their moult cycle and the development of their gonads. The animals were collected with an otter-trawl in the Ubatuba region (23°26'S 45°02'W) every other month from July 1991 to ...

Reproductive features of the swimming crab Callinectes danae(Crustacea, Portunoidea) on the subtropical coast of Brazil: a sampling outside the estuary [PDF]
The life cycle of the crab Callinectes danae is estuarine-dependent, and studies on aspects of their biology should also cover marine areas. The present study investigated the sexual maturity, as well as habitat preference by adults in different gonadal ...

Age and growth of Callinectes danae (Brachyura: Portunidae) in a tropical region [PDF]
Some 2178 male and 2109 female Callinectes danae Smith, 1869 were caught in Northeastern Brazil, from March 2009 through February 2010; we reared 24 males and 24 females for 6 months. The relative growth (relation between weight and cephalothorax width) showed negative allometry, except in adult males.
