<abstract language="eng">Anchovies are members of the Engraulidae family, characterized to present coastal pelagic habits, concentrating in large schoolings distributed among the continental shelf and semi-closed environment, like bays, where they are target of heavy fisheries. The present study aims to describe spatial and temporal distribution of Cetengraulis edentulous (Cuvier, 1828) in the Sepetiba bay (22º54'-23º04'S, 43º34'-44º10'W) and to assess influences of environmental variables on fish occurrence. A monthly sampling programme was carried out between October 1998 and September 1999, to take both, fish and environmental information on temperature, salinity and depth. Three bay zones were established based on spatial gradient of salinity and depth. Adults C. edentulus were more abundant in the inner bay zone; seasonally, larger size groups (total length > 16 cm) occurred in spring/summer. Significant negative correlations were found between fish abundance and salinity and depth. The close relationship of this species to innermost areas in bays, and the absence of juveniles in sandy beaches, suggest that young-of-the-year use mangrove areas as recruitment sites
