Abstract
Fish fauna species can show spatial and temporal patterns, which can be revealed by species association or species groups as well as by species preference to certain habitats. A study was conducted in 2010 in the Capanema and Caeté rivers located in Bragantina Region. A total of 294 fish were collected, belonging to three orders, seven families, 20 genera and 21 species. The species richness was highest in a Caeté E4 stretch, with 20 species. Simpson’s Diversity Index in a Capanema E4 showed the highest species dominance, while Shannon’s Diversity Index showed that the Caeté E3 stretch had the greatest diversity. The importance of these findings is not restricted to knowledge of the fish community structure in watersheds, but has its practical and fundamental side to show the possibility of further studies in other areas.
