Freshwater Jade Perch


Jade perch are a medium to large size grunter species heavily built body and small head, silver/black with irregular black blotches. Common length is 25cm-40cm. In the wild they are usually found in turbid waters of large rivers and waterholes.

The name Jade perch was adopted by the Aquaculture Association of Queensland [AAQ] members as a preferred name for the on selling to the restaurant trade. “Jade Perch” comes from the jade colour seen along the dorsal area of the fin.

Jade perch can’t tolerate cold temperatures but grow relatively fast in warmer conditions. They are easily weaned onto pelleted fish feed and their feeding behaviour is normally vigorous to extreme. They stop feeding when water temperature gets below 18 degrees.
