Population ecology of the blue crab Callinectes danae (Crustacea: Portunidae) in a Brazilian tropical estuary.
This paper aims at describing the population ecology of the swimming crab Callinectes danae Smith, 1869 in one of the most productive estuaries of Brazil, the Santa Cruz Channel. These crabs were monthly collected from January to December/2009 at four stations along the channel, two in the upper and two in the lower estuary. A total of 2373 specimens of C. danae were collected during the study....
متن کاملMercury Levels in Selected Tissues of Blue Crab Thalamita prymna (Portunidae) from Musa Estuary, of the Persian Gulf
Content of mercury in hepatopancreas, muscle and exoskeleton of blue crab T. prymna from Musa estuary and their relationship with size of the organism and season were determined. Mean concentration of mercury in hepatopancreas, muscle and exoskeleton were 1.23, 0.61 and 0.41 µg/g dw, respectively. There was significant difference (p<0.05) in mercury levels depending on the sex with greater ...

متن کاملGenetic population differentiation of the blue swimming crab Portunus pelagicus (Portunidae) in Thai waters revealed by RAPD analysis.
Genetic diversity and population differentiation of the blue swimming crab, Portunus pelagicus, in Thailand were analyzed by RAPD analysis. One hundred and twelve RAPD fragments were generated from 109 individuals of P. pelagicus using OPA02, OPA14, OPB10, UBC122, and UBC158 primers. The percentage of polymorphic bands in each geographic sample and that of each primer across overall samples wer...
متن کاملJuvenile development of Callinectes danae Smith, 1869 (Crustacea, Decapoda, Brachyura, Portunidae) under laboratory conditions.
The juvenile development of Callinectes danae was investigated from megalopae obtained in neuston samples at Ubatuba, São Paulo, Brazil. The individuals were raised in the laboratory under constant temperature (25 ± 1°C), filtered sea water from the collection location (35‰), and natural photoperiod. Newly hatched Artemia sp. nauplii were offered as food on a daily basis and ornamental-fish foo...
