Males And Females

The population structure, size at maturity, reproductive period, recruitment and habitat use were studied in a population of the grapsoid crab Cyrtograpsus altimanus in an intertidal mussel bed at San Antonio Bay, Argentina. Samples were taken from October 2000 to January 2002. Crabs were sized and sexed to estimate size–frequency distributions (SFD). Modal groups of males and females were the same. Growth, evidenced by the shift to right of SFD modal classes, was observed in spring, summer and autumn. Size at maturity of females varied seasonally. Ovigerous females were found in winter, spring and summer, but two discrete recruitment events (in spring and autumn) are proposed. Based on the maximum male and female sizes found in the mussel bed, a size constraint is proposed that forces large crabs to migrate to cobblestone adjacent habitats.

Intertidal Mussel

Fluctuations and vertical gradients of particulate organic matter (POM, as indicated by chlorophyll a and phaeopigments) concentration over an intertidal mussel bed were studied over fortnightly tidal cycles. Chlorophyll a variations were not associated with wave amplitude, tidal energy, and sigma-t, and phaeopigment concentration was correlated positively with wave amplitude only. Comparison of total pigment concentration in water pumped simultaneously from within 5 cm and from 50 cm above the mussel bed showed significant depletion of POM nearest to the mussel bed throughout the first of the two fortnightly tidal cycles studied. During this period, POM depletion was negatively correlated with current speed, but not with mussel filtration rate, nor with wave energy. During the other period, POM depletion was significant in three of the six semidiurnal tidal cycles studied, and depletion was negatively correlated with wave energy only. Our data indicate that food is often depleted immediately above mussel populations, and that water movement is critical in determining food availability for suspension feeders.
