reference points (such as F or SPR thresholds) for management may mask the risk of localized resource decline. Without
accounting for the spatial structural characteristics of the L. polyactis population, the recovery of the overall stock status in
recent years indicated by the stock assessment model may mask the differences in recovery among distinct subpopulations,
which could potentially lead to inappropriate management adjustments, such as the misallocation of fishing effort. Conducting
resource assessments that incorporate spatial dimensions and implementing regionally differentiated resource management are
key approaches to maintaining the productivity of L. polyactis populations in the Yellow and Bohai Seas and enhancing their
resource sustainability. This study presents a novel integrated analytical framework that couples spatio-temporal distribution
with stock status and their driving factors, which can be extended and applied to the analysis of population dynamics and the
formulation of management strategies for exploited fish species in the Yellow and Bohai Seas and even global marine waters.
