Growing barramundi

Stocking rates

Commercial growout in ponds or recirculating systems starts once the fingerlings reach 30-100mm. Fingerlings are stocked at up to 15kg per cubic metre of water.

Feeding

The fingerlings are fed a semi-floating pellet 5-6 times a day when they are small. This decreases to 1-2 times a day as they grow. Pellet size increases as the fish size increases. Farmers feed their fish pellets until all feeding ceases.

The amount of feed required by a fish decreases rapidly with a decrease in water temperature. Maximum intakes occur at 27-29oC and decreases to almost zero at 20oC. Feed conversion ratios (total weight of fish produced per total dry weight of feed consumed) of 1.2:1 to 1.8:1 can be expected in well-managed operations at optimum temperatures.

Annual production from ponds can reach 30t per hectare but is more often 10-15t per hectare.
