This research organized the historical changes in fishing catch data in Lake Biwa and proposed a new framework that integrates fisheries resource management and cultural landscape conservation. It clarified how, since 1960, the change in statistical aggregation methods from the port and regional levels to aggregated values for the entire Lake Biwa area has made it difficult to understand the unique fishing activities and environmental changes in the region. In addition, we presented a new perspective on reevaluating catch data not simply as an indicator for resource management, but also as an indicator for showing changes in cultural landscapes. Based on these findings, we proposed a new evidence-based policy framework that includes detailed data collection using citizen science methods, integration of quantitative data and qualitative value assessment, and policy formation through collaboration with diverse stakeholders.
