AbstractThe purpose of this study was to analyze the taxocenose of marine catfish in the complex bay-estuary of Sao Vicente, Brazil. The sampling was done monthly from September/2000 to August/2002, in four places of the estuary. Were caught 3.985 individuals belonging for 5 genus and 6 species, totalizing 47.807 g. The specie Cathorops spixii showed the biggest plentiful with 1.569 individuals sampled. In the transect I (close to the coastal region), it was registered the biggest richness (6 species) and in the transect IV (upper estuary) the biggest number of individuals (n = 2.602) e weight of 26.236 g. In March/2002 were registered the biggest occurrence with 687 individuals and biggest weight in February/2002 (8.816 g). The bottom water salinity, in the time of study, changed between 14 and 36, and the water temperature varied between 19 and 30 °C. In the sample place juveniles and adults' individuals were caught, a mostly juvenile which demonstrates that of this place shows favorable conditions for growth.
