Abstract
Cherax destructor was grown in four, 0.1 ha ponds with a shallow 'V' shaped bottom profile. Clover, Trifollium repens, was grown in three ponds as forage and flooded in three stages to optimize natural water column production and the provision of microbially enhanced detrital forage. The fourth pond had no forage crop sown in it. Animals (0.025 g in weight) were stocked at the rate of 7 to 8 m-2. Water level was raised in three stages. The flooding of ponds to rise water level tended to result in an increase in chlorophyll a. Changes in dissolved oxygen and chlorophyll a concentrations are discussed. Yield in cropped ponds after a 120 day growing period ranged from 411.1 to 626.0 kg ha-1. Yield from the uncropped pond was 350 kg ha-1. Highest yield occurred in the pond with the highest crop organic matter levels.
