Most of the research into silver perch production has focused on pond based culture, however, some farmers are currently experimenting with intensive recirculation tank system farming for the over-wintering of fingerlings. The silver perch also act as a host for the larval mussels to develop into new baby mussels. These production systems should increase production of silver perch significantly.

Commercial feeds for silver perch are available in pellet form, with either sinking or floating properties. Habitat destruction and fishing have caused natural populations to drastically decline, leading to listing the species as vulnerable. In aquaculture farms, sexually mature silver perch broodstock are induced to spawn, often with a hormone injection of human chorionic gonadotropin (HCG). This occurs as a result of fatty tissues in the fish absorbing compounds released by blue green algae in the culture ponds. In the 1970's the Narranderra Fisheries Research Station began research on the hormone induced spawning of perch, and this technology was made available to industry in the early 1980's.
