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 microm 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 microm for embryos in the early stage of development and from 250 to 345 microm for those in mid-developmental stage, while in C. granulatus from 250 to 345 microm and from 260 to 365 microm 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.
在巴伊亚桑博罗蒙邦野生动物保护区开展的这项研究的目的是分析颗粒招潮蟹（Chasmagnathus granulatus）和乌拉圭招潮蟹（Uca uruguayensis）繁殖力的最相关方面。采样时间为2001年3月至2003年2月。在春季和夏季发现了抱卵的乌拉圭招潮蟹雌蟹（N = 13）和颗粒招潮蟹雌蟹（N = 25），前者的头胸甲宽度（CW）在9.1至11.7微米之间，后者在22.8至32.4毫米之间。乌拉圭招潮蟹发育早期胚胎的卵直径在245至260微米之间，发育中期胚胎的卵直径在250至345微米之间，而颗粒招潮蟹的卵直径分别为250至345微米和260至365微米。乌拉圭招潮蟹的繁殖力为每窝1126至6745枚卵，颗粒招潮蟹为每窝15688至57418枚卵。对于那些处于发育中期有卵窝的雌蟹，建立了几种关系。对于乌拉圭招潮蟹，在以下关系中获得了最佳相关系数：雌蟹体重与卵块重量以及头胸甲宽度与卵块重量；对于颗粒招潮蟹，在雌蟹大小与卵数和卵块重量之间获得了最佳关联。
