Genus

Pseudoplatystoma

3 species

Pseudoplatystoma is a genus of several South American catfish species of family Pimelodidae. The species are known by a number of different common names. They typically inhabit major rivers where they prefer the main channels and tend to stay at maximum depth, but some species can also be seen in lakes, flooded forests, and other freshwater habitats. They have robust bodies, and are important food fish. Recently, their population size has been on the drastic decline due to a variety of factors including overfishing and habitat destruction due to the construction of hydroelectric dams.

The distribution of Pseudoplatystoma species includes the great river basins of South America: the Amazon, Orinoco, Paraná, São Francisco, Magdalena, Rupununi, Essequibo, and Suriname Rivers. They can also be found in the Cuiabá river, located in the Brazilian State of Mato Grosso.They have not been reported from river basins draining into the Pacific. P. fasciatum inhabits the Guyana region, including the Essequibo and Suriname Rivers and their tributaries, in Guyana, Suriname, and French Guiana. P. tigrinum is found in the Amazon River in Brazil, Colombia, Ecuador, Peru, and Venezuela. P. corruscans originates from the Paraná and São Francisco Rivers in Argentina, Brazil, Paraguay, and Uruguay. P. orinocoense is named for and endemic to the Orinoco River of Venezuela. P. metaense is distributed in the Orinoco River in Colombia and Venezuela; it is named for the Meta River, the type locality, a tributary of the Orinoco River. P. magdaleniatum is named for and endemic to the Magdalena River drainage, including the Cauca River of Colombia. P. reticulatum inhabits the central Amazon and Paraná Rivers in Argentina, Bolivia, Brazil, Paraguay, and Uruguay.

Pseudoplatystoma species live in a diverse range of habitats, such as great rivers, lakes, side channels, floating meadows, and flooded forests. P. fasciatum is found in river beds and sometimes in flooded forests. Though it is biologically similar to P. tigrinum, this fish seems to favor shadier streams. P. tigrinum occurs in estuarine zones, mainly upstream of the first rapids up to the basin's headwaters. They live in the main bed of slow or fast zones, and the juveniles particularly live in flooded forests.
