Implications on the Pb bioaccumulation and metallothionein levels due to dietary and waterborne exposures: The Callinectes danae case [PDF]

Ecotoxicology and Environmental Safety, 2018
This study aimed to assess the bioaccumulation of Pb and induction of metallothionein-like proteins (MT) in Callinectes danae through single and combined dietary and waterborne exposures. Male C. danae individuals were collected in the south area of the Cananéia-Iguape-Peruíbe Protected Area (APA-CIP), in São Paulo State, Brazil.

Effect of diet during larval development of Menippe nodifrons Stimpson, 1859 and Callinectes danae Smith, 1869

Aquaculture International, 2020
The worldwide decrease in fishery stocks in recent years is related to the degradation of coastal environments and to the increases in capture effort and extreme natural events. Restocking dilapidated populations with artificial hatchery-reared larvae has arisen in recent years as a viable technique for the reparation and maintenance of stocks of ...

The Reproductive Cycle of Callinectes Danae Smith, 1869 (Decapoda, Portunidae) in the Ubatuba Region, Brazil

Crustaceana, 1998
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 ...

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)

Archives of Veterinary Science, 2015
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.

Reproductive features of the swimming crab Callinectes danae(Crustacea, Portunoidea) on the subtropical coast of Brazil: a sampling outside the estuary [PDF]

Brazilian Journal of Biology, 2015
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 ...

Swimming behavior of newly hatched larvae of six decapod species (Crustacea: Decapoda)

Nauplius, 2021
Crustacean decapod larvae have developed several adaptations to maximize their survival, including swimming behavior. Swimming improves larvae dispersal and contributes to their response to environmental stresses, including variations in abiotic factors,
