The marketization of sea area use rights is a critical mechanism for optimizing marine resource allocation efficiency and achieving the high-quality development of marine economy. Combining the natural attributes of marine resources with policy constraints, this study establishes a supply–demand theoretical model for sea area use rights transfer within the market equilibrium theory framework. Through model solving and equilibr...

Large yellow croaker (Larimichthys crocea) is an economically important marine fish, yet rapid and non-destructive discrimination between sea-caught and farmed collection-source groups remains challenging. This study developed a fish-level analytical workflow integrating YOLO11n-seg instance segmentation with visible–near-infrared hyperspectral imaging to extract relative reflectance ratios from six anatomical regions. The ana...
