The gilded catfish or jau (Zungaro zungaro) is a South American catfish (order Siluriformes) of the family Pimelodidae.

Taxonomy[edit]

By some sources, it is the only species of the monotypic genus Zungaro.[1] However, some sources list other species as valid, such as Zungaro jahu.[2] This species may be referred to by one of its synonyms, Brachyplatystoma flavicans.[3] This species contains two subspecies, Z. z. mangurus and Z. z. zungaro.[4]

Distribution and habitat[edit]

They are sexually mature upon reaching 10 kg (22 lb) weight.[3] This fish native to the Orinoco and Amazon basins; in the Amazon, this fish is found quite upstream, in the main bed of the big tributaries with muddy bottoms.[3]

Description[edit]

This fish reaches 140 cm (55 in) in total length, and specimens measuring 130 cm (51 in) and weighing 50 kg (110 lb) are not rare.[3] These fish are mainly piscivorous, hunt at night, and sometimes go into flood-prone areas of rivers. Some migrations in pursuit of migrating Triportheus and Anodus have been reported. The nursery ground is at the mouths of rivers.[3]
