Post-harvest fish losses remain a persistent barrier to food security, profitability, and sustainability in tropical aquaculture supply chains. This study develops a novel fuzzy-integrated decision-support framework that incorporates both efficiency and stakeholder influence into the House of Risk 2 model, extending it into a multidimensional prioritization tool. The framework combines the Fuzzy Delphi Method to validate expert-driven mitigation options, Fuzzy Data Envelopment Analysis to measure strategy efficiency, and Fuzzy Interpretive Structural Modeling to quantify actor interdependence and influence, integrated through a fuzzy-modified House of Risk 2 model under a triangular fuzzy set environment. Eight mitigation strategies were validated, with capacity building, ice-use training, and market-facility improvement identified as the most effective and feasible. The model offers a data-driven approach for designing resource-efficient and institutionally coordinated mitigation strategies, highlighting the need for synergistic technical, infrastructural, and governance actions to achieve Sustainable Development Goal targets 12.3 and 14.7. © 2026 Chinese Institute of Industrial Engineers.
