Growing and harvesting jade perch

Breeding and fry production

In their natural habitat, jade perch spawn during the summer floods when water temperatures are above 23°C. In captivity the sexually mature broodstock are induced to spawn with a hormone injection. (Note: many chemicals used in aquaculture, such as hormones, require veterinary advice and prescriptions before use. Always check before use.)

The first-feeding larvae are about 5mm long and can be reared in a pond environment managed to achieve a stable zooplankton bloom (rotifers and copepods). Survival rates of 30% or higher are possible with larvae metamorphosing into fingerlings in 3-4 weeks (15mm long). Fingerlings can grow to 30-50mm in 8-12 weeks. These fingerlings can then be stocked into growout ponds or recirculation systems.
