Dissolved oxygen is an important parameter of water quality in aquaculture. Aeration has been known to improve oxygen levels and yields, but its use is uncommon in many developing world environments due to high costs. As a more effective implementation, this thesis presents the use of a feedback diffused aeration control system to maintain adequate oxygen levels and increase energy savings. To demonstrate the potential, a model was developed to describe the interaction between the aerator and the pond and to predict the oxygen profiles of the water. Time-series simulations were performed to estimate the potential savings for a pond in Bangladesh, with and without the use of a feedback system. Results showed that the use of a control system led to an average of 66.0% in energy savings. Field validation experiments indicated an average prediction error of 3.64% and 4.91% for the top and bottom layers of the pond.
