Simulations have been conducted to suggest general principles for the arrangement of aerators within a rectangular pond used for the growout of marine shrimp such as Penaeus monodon and Penaeus japonicus. Computational fluid dynamic models were produced for three schemes that were identified in a survey of Australian Prawn Farming Association members. These arrangements are 'in-line' (series), 'parallel' (side by side), and 'diagonal' (diverting apart). Model results were assessed on the basis of benthic shear stress by classifying regions of pond bottom as 'red zone' (excessive stress), 'green zone' (desirable), and 'dead spots' (sediment traps). A comparison of results indicates that conventional aerators should be arranged diagonally or in parallel. It is also apparent that low-speed operation would be advantageous. These recommendations are consistent with the long-established practice of establishing pond-wide circulation.
