Descripción
The aim of the present work conducted at the Refugio de Vida Silvestre Bahía Samborombón is to analyse the most relevant aspects of the fecundity of Chasmagnathus granulatus and Uca uruguayensis. Samplings were carried out from March 2001 to February 2003. Ovigerous females of U. uruguayensis (N = 13) and C. granulatus (N = 25) were found during spring and summer, their sizes (CW) varied from 9.1 to 11.7 mm for the former species and from 22.8 to 32.4 mm for the latter. The egg diameter in U. uruguayensis ranged from 245 to 260 ?m for embryos in the early stage of development and from 250 to 345 ?m for those in mid-developmental stage, while in C. granulatus from 250 to 345 μm and from 260 to 365 ?m respectively. Fecundity varied from 1126 to 6745 eggs/brood in U. uruguayensis and 15688-57418 eggs/brood in C. granulatus. For those females with broods in mid-developmental stage, several relationships were made. For U. uruguayensis the best correlation coefficients were obtained for the relationships: female weight vs. egg mass weight and carapace width vs. egg mass weight; for C. granulatus the best association was obtained between female size and the egg number and the egg mass weight.
O objetivo do presente trabalho foi analisar os aspectos mais relevantes da fecundidade de Chasmagnathus granulatus e Uca uruguayensis no Refúgio da Vida Silvestre Bahia Samborombón. As amostragens foram realizadas de março de 2001 a fevereiro de 2003. As fêmeas ovígeras de U. uruguayensis (N = 13) e de C. granulatus (N = 25) foram capturadas na primavera e verão. A largura da carapaça (LC) de U. uruguayensis variou de 9.1 a 11.7 mm, e de 22.8 a 32.4 mm para C. granulatus. O diâmetro dos ovos de U. uruguayensis variou de 245 a 260 µm para embriões em estágio de desenvolvimento inicial e de 250 a 345 µm para aqueles em estágio intermediário; para C. granulatus as variações foram de 250 a 345 µm e de 260 a 365 µm, respectivamente. A fecundidade de U. uruguayensis variou de 1126 a 6745 ovos/desova e para C. granulatus de 15688 a 57418 ovos/desova. Para as fêmeas com massa de ovos em estágio de desenvolvimento intermediário foram efetuadas várias relações: para U. uruguayensis os melhores coeficientes de correlação foram obtidos nas relações: peso da fêmea vs. peso da massa de ovos, e largura da carapaça vs. peso da massa de ovos. Para C. granulatus, a melhor associação foi obtida entre o número de ovos e o peso da massa de ovos.
