The northern rivers catfish (Neoarius utarus), also known as the salmon catfish,[2] is a species of catfish in the family Ariidae.[3] It was described by Patricia J. Kailola in 1990, originally under the genus Arius.[1] It inhabits freshwater bodies in Indonesia and Papua New Guinea.[3]

Its diet includes finfish, detritus, terrestrial invertebrates, and caridean shrimp such as those in the genus Macrobrachium.[4]

The Northern rivers catfish 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 (3.7 lb). It is closely related to Neoarius leptaspis, and is frequently mistaken for it.[3]

The Northern rivers catfish spawns throughout the year.[5][6] It is harvested by subsistence fisheries.[3]
