69KK jpeg 250mm (10in) TL fish from the Langlo River, Charleville, Queensland. Peter Unmack photo.
Up to about 600mm (2ft) TL and 8kg (17lb).
Silver perch have been stocked into Clayton Bore which leads into Lake Eyre (Unmack unpub. data). It has probably been introduced elsewhere, as it is a popular angling/eating fish, and fingerlings are readily available. There is also little monitoring on where fish hatcheries send fish to, even though it is illegal to translocate species outside their natural ranges.
Murray-Darling Drainage Basin in south-eastern Australia.
The primary threat is hybridisation with Welch's grunter, a very closely related species. However, it is not known if hybridisation will occur between them.
