Abstract
A. lacustris is a widely distributed species in the Sao Francisco and Parana river basins, mainly in lentic waters. Specimens were captured monthly, over a whole year in a reservoir built by damming the Ribeirao Claro stream (SP). The stomach contents analyses showed a predominantly piscivorous diet. Feeding activity showed to be clearly less intense during winter, when all the sampling groups were compared. Despite the fact that the diet of A. lacustris presents a high diversity of prey-species, the prey size, their abundance and also behavior possibly determined a certain preference for some of them.
