Physiologic sexual maturity of the fiddler crab Uca rapax (Smith, 1870) (crustacea, ocypodidae) from two mangroves in Ubatuba, Brazil

The gonad development of Uca rapax was studied to achieve the size at onset of its sexual maturity. Crabs were sampled from April/2001 to March/2002 in the Itamambuca and Ubatumirim mangroves in Ubatuba, São Paulo, Brazil. The specimens were grouped in 10 size classes. Juveniles and adult crabs freq...

Juveniles and adult crabs frequencies were assessed for each class. The size of carapace width in which 50% of males and females were considered mature was 14.8 and 12.1 mm (Itamambuca) and 13.6 and 11.4 mm (Ubatumirim), respectively for males and females. Males matured at higher sizes than females, probably due to a major investment in their somatic growth, while females spend their energy in the reproductive process, saving energy for eggs' production.Group of Studies on Crustacean Biology, Ecology and Culture - NEBECCDepartment of Zoology Institute of Bioscience UNESP, 18618-000; Botucatu - SPDepartment of Zoology Institute of Bioscience UNESP, 18618-000; Botucatu - SPGroup of Studies on Crustacean Biology, Ecology and Culture - NEBECCUniversidade Estadual Paulista (Unesp)2014-05-27T11:21:49Z2014-05-27T11:21:49Z2006-03-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article239-248application/pdfhttp://dx.doi.org/10.1590/S1516-89132006000300009Brazilian Archives of Biology and Technology, v. 49, n. 2, p. 239-248, 2006.1516-8913http://hdl.handle.net/11449/6879810.1590/S1516-89132006000300009S1516-89132006000300009WOS:0002368357000092-s2.0-337466380522-s2.0-33746638052.pdfScopusreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPengBrazilian Archives of Biology and Technology0.6760,281info:eu-repo/semantics/openAccessCastiglioni, Daniela Da SilvaNegreiros-Fransozo, Maria Lucia [UNESP]2025-10-24T03:49:13Zoai:repositorio.unesp.br:11449/68798Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestrepositoriounesp@unesp.bropendoar:29462025-10-24T03:49:13Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
