- Crecimiento Somático del Cangrejo Violinista Uca rapx (Smith, 1870)(Brachyura: Ocypodidae) de dos manglares subtropicales de Brasil Daniela Castiglioni da Silva Daiana Castiglioni da Silva Maria Lucia Fransozo Negreiros Agrociencias age Uca rapax mangroves somatic growth subtropical region The crabs were collected monthly, from April 2001 to March 2002 in the mangroves of Itamambuca and Ubatumirimin Ubatuba, São Paulo, Brazil, using the procedure of catch per unit effort (cpue) during 15 minutes at low tide periods bydigging the burrows. The sex and carapace width (mm) were recorded for each crab in a sample of 1 294 crabs in Itamambucamangrove (667 males and 627 females) and 2 107 crabs in Ubatumirim (1 117 males and 990 females). The somatic growthherein described is based on analysis of frequency distributions in size classes using the von Bertalanffys growth model. Thegrowth curves based on the carapace width (mm) of males and females are described respectively by the equations: Wt=23.9[1-e0.21(t+0.87)] and Wt=23.8[1-e0.16(t+1.18)] in Itamambuca and Wt=21.3[1-e0.16(t+1.12)] and Wt=20.4[1-e0..15(t+1.29)] in Ubatumirim mangrove.The crabs from Itamambuca reached their maximum age in 1 620 days (males) and 1 800 days (females), while those fromUbatumirim, required 1 440 days (males) and 1 560 days (females) 2004 artículo científico 0186-2979 https://www.redalyc.org/articulo.oa?id=15403903 en http://www.redalyc.org/revista.oa?id=154 Universidad y Ciencia application/pdf Universidad Juárez Autónoma de Tabasco Universidad y Ciencia (México) Num.20 Vol.39
