Bioecology of Acestrorhynchus britskii (Pisces

Efforts to study the bioecology of Neotropical fishes are necessary in view of the advances in human activity on habitats and the rapid loss of fauna observed mainly in aquatic ecosystems in the river basins of this region which are mostly fragmented by the construction of dams. In Brazil the São Francisco basin is the largest basin entirely located in the country but studies on the bioecology and fisheries biology of its ichthyofauna are still scarce. This work aims to encourage ecological studies of species that may be affected by the damming of the São Francisco.
