    This study proposes an Optical Flow-based video analysis method for quantitatively estimating feeding responses and residual feed in olive flounder ( Paralichthys olivaceus) aquaculture. In flounder farming environments, direct measurement of feed consumption is challenging due to fine feed particles and high stocking density. To address this limitation, we applied FlowDiffuser, a deep learning-based Optical Flow algorithm, to quantify pixel-level motion between frames and employed an adaptive threshold based on the 80th percentile to filter out environmental noise caused by lighting changes and water surface ripples. Multi-temporal scale analysis revealed that a 1-minute moving average is optimal for detecting feeding responses, while a 120-minute moving average during nighttime is effective for estimating residual feed. Experimental results demonstrate 92% accuracy in feeding response detection (46 out of 50 instances) and 80% accuracy in residual feed estimation (8 out of 10 instances). This study demonstrates that feeding status can be indirectly assessed through behavioral changes of the fish population, even in high-density aquaculture environments where direct detection of individual feed particles is difficult. The proposed method provides a foundational technology for developing automated feeding systems in aquaculture.
