Abstract：Accurate assessment of the scaleanddistribution of offshore marineaquaculture iscritical for effective management，spatial planning，andecological protection.Thisstudyemployed high-resolutionSentinel-2A/Batellite imagery，a U-Netdeeplearningmodelforautomaticfeatureextraction，andhuman-computerinteractivecorrctiontomap the spatialextent of raft-based kelpfarming in Heiniwan Bay from2016 to2024.Theanalysisrevealedathree-phase development trajectoryintheaquaculture areaover thenine-yearperiod.Spatialdistribution exhibitedastable“north-south agglomerationwith central sparsity”patern.The observed spatiotemporal dynamics reflectthe combined influence of technolgical advancements，policy interventions，andnatural environmental conditions.These findings oferarobust scientific basis foroptimizingaquaculture zoning，adaptive management strategies，and ecological governance in coastal regions with comparable aquaculture practices and environmental settings.
