Abstract: The present study focused on the decapod fauna of the fluvial-estuarine environment of the Guajará Bay, in the Brazilian state of Pará, where specimens were collected monthly from six sites, from May 2006 to April 2007. A total of 6,793 specimens were captured, belonging to 11 species of crab and shrimp: eight palaemonids - Macrobrachium amazonicum (Heller, 1862), Macrobrachium surinamicum Holthuis, 1948, Macrobrachium carcinus (Linnaeus, 1758), Macrobrachium rosenbergii (De Man, 1879), Macrobrachium spp. 1-4 -, one portunid - Callinectes bocourti A. Milne-Edwards, 1879 -, and two trichodactylids - Sylviocarcinus devileii H. Milne-Edwards, 1853 and Sylviocarcinus pictus (Milne-Edwards, 1853). While no significant differences were found in the ecological indices of diversity with respect to season, site, or trap size, a tendency for increased abundance and species richness was found during the dry season (August-November), in particular at some sites, apparently reflecting the influence of the estuary's saline wedge.
