Description

The silver perch is a fish of the grunter family (Terapontidae) from the Murray-Darling basin in Australia. The species grows to about 40 cm and has a stocky, silver-grey body with a small head. Adults live in rivers, lakes and reservoirs and prefer fast-flowing water of rapids, often in groups just below the surface near rapids and weirs. As an omnivore it feeds on algae, water plants, insects and small invertebrates. Owing to dams and habitat loss the species is considered near threatened. It is a food fish and is harmless to humans.
