Abstract

The aquatic biodiversity of the Amazon basin is heavily influenced by environmental factors, such as altitude, rainfall cycles, and dry seasons. These factors impact the water's physical and chemical parameters, consequently affecting the distribution and diversity of fish. The order Siluriformes Cuvier, 1817, particularly the family Pimelodidae Bonaparte, 1835, is ecologically and economically significant due to its migratory behavior and dependence on the region's water variability. The genus Brachyplatystoma Bleeker, 1862 includes species of high commercial value, such as “dourada” Brachyplatystoma rousseauxii (Castelnau, 1855) and “piramutaba” Brachyplatystoma vaillantii (Valenciennes, 1840) and is fundamental to fishing in the Amazon. This study provides a thorough review of the taxonomy, ecology, migration, and genetic diversity of species in this genus. Information was collected from scientific articles, theses, and books using databases such as Scholar Google, SciELO, Scopus, Web of Science, WoRMS, Consensus, and INPA databases. The results underscore the significance of morphological and ecological adaptations in response to the seasonal dynamics of Amazonian rivers. Additionally, eco-morphological analyses reveal essential information about habitat use, resource sharing, and evolutionary patterns shaped by environmental pressures and phylogenetic constraints. These data are essential for developing sustainable fisheries management strategies and conserving aquatic biodiversity in the Amazon.
