The Trout Cod is a large, deep-bodied species that has a big mouth and a straight head profile. It can be recognised by its overhanging upper jaw and the presence of a dusky horizontal stripe from the snout, through the eyes and onto the preoperculum.
In life, the fish is bluish grey or brown, with irregular spots and bars on the upper and lateral surfaces of the body as well as on the soft dorsal, anal and caudal fins. It is pale ventrally.
It is usually found in rapidly flowing freshwater streams, often near snags or over rocky or gravel substrates. Larger fishes are found in deeper water.
The species is endemic to Australia, occurring in scattered localities within the Murray-Darling system. Some fish have been translocated to coastal New South Wales.

Feeding and diet
Adult and juvenile fish eat other fishes, crustaceans, aquatic insects and molluscs. Larvae feed on zooplankton.
The Trout Cod is now listed as a threatened species, largely due to habitat degradation. It originally occurred widely throughout the southern Murray-Darling River system of New South Wales, the Australian Capital Territory, Victoria and South Australia. This fish has been a popular angling species, but it can no longer be taken in New South Wales, the Australian Capital Territory and Victoria.
