Size frequency distribution (SFD) of males and females collected from quadrats (white bars, population samplings) and traps (gray bars) in salt marshes and mudflats of MC Mar Chiquita, BB BahÃa Blanca and SA San Antonio (all seasons pooled). χ2: statistic of Chi-square test to compare SFD of population and traps. Z: statistic of z test to compare proportions of males in populations and in traps. p: significance of tests. To compute Z test, only crabs >18 mm AC in MC and >14 mm AC in SA and BB were considered
