Abstract: This study employs computational fluid dynamics (CFD) to analyse water flow created by a Taiwanese paddlewheel aerator in an aquaculture tank. By simulating several rotational speeds (30,70, and 103 rpm), the research examines the inefficiencies caused by higher speeds, where lifted water falls back into its original position, which is counterproductive in terms of water aeration These findings are critical for optimizing aerator performance to enhance oxygen transfer, a key factor for sustaining water quality in fish farming operations. The oxygen transfer rates derived from the CFD model will serve as input for a fish growth simulation model currently under development. This integrated approach will allow for more precise predictions of fish growth by correlating oxygen availability with physiological factors, ensuring improved aquaculture management and operational efficiency.
