The Barcoo grunter, Scortum barcoo, is a freshwater finfish native to the Lake Eyre and Bulloo-Bancannia catchments. The natural habitat of the barcoo grunter includes the low gradient rivers and creeks of the Lake Eyre Catchment. Waters are generally highly turbid and have a wide temperature and conductivity range.

Barcoo grunter is marketed under the name Jade perch.

It should be noted that currently, very little independent research on the aquaculture of Jade perch has taken place. The species is readily produced by hatcheries and has shown early success in pond growout and intensive tank culture. There is a narrow range where optimum growth rates occur which is probably 22⁰C to 28⁰C. Growth is negligible below 20⁰C. Marketable fish of 350 to 800gms can be grown in 8 to15 months in earth ponds.

Barcoo grunter is one of Australia’s many grunters. It is a heavily built fish with a small head. They are generally uniformly brownish-black. The fins are usually darker in colour than the body. These fish can be distinguished by their anal fin which has 8 rays. The Barcoo grunter are usually caught around 25cm to 30cm, but have been reported to 35cm.

The Barcoo Grunter is grown in Gippsland in controlled recirculation systems to marketable grow-out size

Limited commercial experience suggests that Jade perch appear to be well suited to production in well-managed recirculation tank systems with the aid of effective biological filtration. Limited commercial production has also occurred in purpose built earth ponds. Pond sizes can vary from 0.2 to 0.5 hectare surface area with depths of 0.7 to 2.5 metres. It is an advantage to have all ponds easily drainable.
