Distribución de capturas:
Maparás potential yield was estimated to be approximately 12,600 tons. Four important fishery regions accounted for 92% of potential yield: Tocantins (39%), Estuary (20%), Lower Amazon (18%) and Central Amazon (16%).
Notas de historia natural:
Hypophthalmus marginatus and H. edentatus are the two species most commonly exploited. Mapará yields are closely linked to phytoplankton production in the mouth-bay lakes of the lower Tocantins River, lower Xingu River and large floodplain lakes. Mapará are popular food fishes because of their high fat content. These catfish are migratory but they are captured on a large scale only while migrating in the Tocantins River and perhaps in the Xingu River as well. Elsewhere they are taken when feeding on plankton in open waters. The closing of TucuruÍ Dam resulted in a crash of mapará populations downstream of the impoundment but these seem to have somewhat recovered in the last few years.
