| Callinectes danae (Smith, 1869), siri-azul, constitui um importante recurso pesqueiro nos estuários dos rios Botafogo e Carrapicho. O objetivo do presente estudo foi estimar a maturidade sexual das fêmeas de C. danae. Os espécimes foram capturados, entre outubro de 2003 a junho de 2004, com auxílio de um barco de pesca equipado com rede de arrasto do tipo "wing-trawl" e arrastados durante 5 minutos. No laboratório, os siris foram contados, numerados, sexados, pesados e mensurados. A largura da carapaça (LC) foi medida na base do espinho lateral e a largura do abdome (LA) mensurada na altura da articulação do quinto esternito abdominal. Um total de 596 fêmeas de C. danae foram analisadas: 417 (69,97%) no rio Botafogo e 179 (30,03%) no Carrapicho; as fêmeas... |

| The C. danae females were collected monthly, within the period of April/91 to March/92. The monthly average variation of the condition factor (Ø1), is associated, among other causes, to both the weight of the gonads (Ø3) and the stomach (Ø2). The difference between Ø1 and Ø3 (ΔØ) estimates the "gonadal condition" showing highest values on the reproductive cycle (May, November, January and March). These months coincide with the highest values of the gonadossomatic index. So can be used as an indicative of the period of spawning of Callinectes danae in Lagoa da Conceição, Santa Catarina, Brazil. |

| Studies on the growth of the blue crab C. danae were carried out by the analysis of size-frequency distributions, and the growth curves were determined for both sexes through Bertalanffy equation. 613 males and 511 females were obtained from 10 collecting sites of the lagoon, at night, monthly from January/88 to July/89. The growth curves in carapace width were described according to the following equations: Wid∞ = 14.0 (1-e-0,6975.t) for males and Wid∞ = 13.3 (1-e-0,6555.t) for females. The growth curves in body weigth were also determined, based on the equations of the growth curves and the relationship between body weight and carapace width. The equations are:Wt = 156.9 (1-e-0,6975.t)2.9153 for males, Wt = 134.0(1-e-0.6555.t)2.8994 for females. |

| Abundance of ovigerous females, size of the first gonadal maturation and the possible migration, route of the blue crab Callinectes danae from the Conceição Lagoon system, Santa Catarina Isle, Brazil, are described. This lagoon is connected with the coastal area through a canal. A total of 1,124 crabs was caught during a 19 month sampling period. The reproduction and recruitment of juveniles occurred all year-round, with two peaks of abundance (February and September), correlated with the presence of ovigerous females (June and January). The mean carapace width at which the crabs attained gonadal maturity for the first time was 9.4 cm in males and 8.4 cm in females. The Conceição Lagoon is a growth, reproduction, and spawning area for the species. However,... |
