Última Aspectos reprodutivos de Goniopsis cruentata (Latreille) (Crustacea, Brachyura, Grapsidae) na Baía de Sepetiba, Rio de Janeiro, Brasil Zoologia Silva,Zilanda de Souza; Oshiro,Lídia Miyako Yoshii. The objective of this study was to get some knowledge about the reproductive aspects of Goniopsis cruentata (Latreille, 1803), concerning through sex ratio, morphological sexual maturity, reproductive period, fecundity and eggs size. The crabs were collected monthly in Itacuruçá's Mangroves from November, 1997 to November, 1998. Four hundred and seven crabs were caught and they were 47% males, 36% females and 17% ovigerous females. The sex ratio was 1:1.13 (male:female) (X²= 1.54, p > 0.05). The relation of abdomen width (AW) and carapace width (CW) in females showed a positive allometric grow (b = 1.36), it suggests the size onset of maturity occur from 26.0 a 29.0 mm (CW) in females. The ovigerous females occured during all the research period, except...

The growth of the crab Goniospis cruentata (Latreille. 1803), was studied in the laboratory, through of the molt increment and intermolt period. A total of 86 crabs (48 males and 38 females) were collected in the ltacuruçá's Mangrove in Mangaratiba's county. Rio de Janeiro. The crabs were maintened in the laboratory in four 1000 l tanks, with continuous water circulation during fifteen months. They were fed each two days with pieces of fish and fruits. The crabs varied in size from 19.3 to 56.0 mm in males and 23.3 to 48.8 mm in females. The males presented until four molts during the experiment and the females until six molts. The molts oceurred during ali the months. The mean percentage of molt increment was 6.1 ± 2.7%, for both sexes and it decreased...

Ano: 2002 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0101-81752002000300028 External factors determining breeding season in the red mangrove crab Goniopsis cruentata (Latreille) (Crustacea, Brachyura, Grapsidae) on the São Paulo State northern coast, Brazil Zoologia Cobo,Valter José; Fransozo,Adilson. This study evaluated the influence of the water and air temperatures, pluviosity and photoperiod on the breeding season of Goniopsis cruentata (Latreille, 1803), in Ubatuba littoral, southeastern Brazilian coast. Monthly collections were conducted out from January/95 to December/96 in an estuarine area from 23º29'10"-23º29'45"S to 45º09'10"-45º10'00"W. Water and air temperature variation showed the highest correlation coefficient with the frequency of ovigerous females, r² = 0.73 and 0.68, respectively. However, an analysis of the set of environmental variables, revealed the photoperiod as the factor of highest association with the ovigerous frequency (r² = 0.68). This degree of association allow us to suggest that the breeding season duration of G....

Ano: 2003 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0101-81752003000200007 Testis and vas deferens morphology of the red-clawed mangrove tree crab (Goniopsis cruentata) (Latreille, 1803) BABT Garcia,Tatiane Martins; Silva,José Roberto Feitosa. The present study describes the structure of the testes and vas deferens of the red-clawed mangrove tree crab, Goniopsis cruentata. Testes and vas deferens were fixed with cold Bouin's solution and submitted to histological routine examinations. Light microscopy showed the testis to be divided into three regions: anterior, containing the germinal zone; intermediary, including the collecting duct; and posterior. The vas deferens, which was continuous with the testes, could be divided into two regions: one corresponding to the expansions and another lined by cubical epithelium, collagenous fibers and a circular layer of muscle cells and containing the androgenic gland. Spermatophores were observed in both vas deferens regions suggesting that they...
