Monthly samples were carried out from September/94 to August/95 in three established sampling sites along the rocky shore. Five species of Porcellanidae were recorded: Pachycheles laevidactylus, P. monilifer, Petrolisthes armatus, Pisidia brasiliensis and Megalobrachium roseum comprising 9,084 specimens.
