The rapid expansion of large-scale aquaculture has created a demand for more efficient and sustainable farming systems. Among these, land-based circular tank is emerging as key solution due to its high efficiency, scalability, effective waste management capabilities. Optimizing the hydrodynamic characteristics these tanks crucial improving water quality ensuring health cultured fish. This study investigates large tanks, focusing on effects pusher configurations presence fish flow dynamics sewage collection efficiency. Field experiments were conducted under two conditions: with without fish, while varying diameter, deployment angles, number pushers. at different layers measured using Acoustic Doppler Velocimetry. results indicate that significant impact field compared diameter. optimal configuration circulation was identified when diameter 11 cm, angle 45°, pushers 6. significantly influenced distribution by expanding velocity zones. findings provide theoretical basis optimizing in thereby contributing improved health.
