Brustiarius utarus, the northern rivers catfish or salmon catfish,[3] is a species of catfish in the family Ariidae.[4] It was described by Patricia J. Kailola in 1990, originally under the genus Arius.[4] It inhabits freshwater bodies in Indonesia and Papua New Guinea.[4]
Its diet includes finfish, detritus, terrestrial invertebrates, and caridean shrimp such as those in the genus Macrobrachium.[5]
Brustiarius utarus reaches a maximum known standard length of 55 cm (22 in), but usually reaches an SL of 30 cm (12 in). It reaches a maximum weight of 1.7 kg (3 lb 12 oz). It closely resembles Bleekeriella leptaspis, and is frequently mistaken for it.[4]
Brustiarius utarus spawns throughout the year.[6][7] It is harvested by subsistence fisheries.[4]
