Abstract


The objective of the present study was to estimate for the fecundity for the C. dance population of estuary of São Vicente, SP, Brazil. To study the fecundity and its relationships to size, and egg size, Carapace width was one of the main factors for the determination of fecundity, which F = -893035,31 ± 20042, 28, ranged eggs, with females of the same size class presenting a wide amplitude of variation. This supports the hypothesis that portunid females present staggered spawning, possibly presenting more than one period of reproduction within one year. C. dane showed lower fecundity than the remaining portunids studied, but they did show a rapid and efficient embryonic development, presumably capable of assuring reproductive success. Although egg loss occurs during embryonic development can be concluded that the fecundity of C. danae is high reproductive effort and significant characteristic of species R strategists.
