The gilded catfish, Jau catfish or dourado catfish, (Zungaro zungaro) is a South American catfish (order Siluriformes) of the family Pimelodidae. It is also known as manguruyu or black manguruyu. ^[2]

Taxonomy

By some sources, it is the only species of the monotypic genus Zungaro. ^[3] However, some sources list other species as valid, such as Zungaro jahu. ^[4] This species may be referred to by one of its synonyms, Brachyplatystoma flavicans. ^[5] This species contains two subspecies, Z. z. mangurus and Z. z. zungaro. ^[6]

Distribution and habitat

They are sexually mature upon reaching 10 kg (22 lb) weight. ^[5] 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. ^[5]

Description

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. ^[5] 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. ^[5]
