They can survive in water with temperatures ranging from 2 C to 35 C. Optimum growth rates occur between 23-28 C and growth is negligible below 12 C. Silver Perch are suited to aquaculture because of their high survival and rapid growth rates. Commercial production normally occurs in purpose built earthen ponds. Recommended pond size is 0.3 to 0.4 of a hectare surface area with depths of 0.7 to 1.5 metres. The ponds should be easily drainable and have a concrete sump to assist in the harvest of stock. A 1.5kg fish may produce up to 500,000 eggs.
Males are difficult to distinguish from femaels by external examination.
However Females are usually larger and more round when spawning. At spawning two or three male fish may follow the female near the surface of the water and activity and speed increase at spawning when fish may thrash the water surface. Eggs are spherical, amber coloured at first but colourless and transparent later, approximately 3m in diameter, non-adhesive and pelagic, but will come to rest on the bottom in still water. Eggs hatch within 30 hours at temperatures between 22 C and 31 C. Fry begin to feed about 5 days after hatching. Silver Perch are omnivores consuming zooplankton, small crustaceans, aquatic insects, molluscs, algae and plant material.
