FBname: New Guinea thryssa
Comments: Inhabits streams and associated lagoons, in clear or turbid water; also in brackish estuaries (Ref. 44894).  A riverine species reaching nearly 900 km up the Fly River, but also down to the estuary.  Found in main river channels as well as smaller tributaries (Ref. 2847).  It forms shoals in deeper water of lagoons.  Breeding biology is poorly understood, but it seems likely that spawning takes place in fresh water as juveniles have been collected from the upper reaches of some Queensland rivers.  The diet consists of small crustaceans, fishes, insects and some plant material (Ref. 44894).  Piscivorous (at least as large adults), recorded as feeding on <i>Clupeoides papuensis</i> and <i>Melanotaenia nigra</i> in the Fly River.  The only anchovy that is restricted to mainly freshwater habitats (Ref. 44894).  The largest anchovy known so far.
