This study evaluates the ecological and socio-economic vulnerabilities of the Philippine fish processing sector to climate change, focusing on the impacts of rising sea surface temperatures under the RCP 8.5 scenario and extreme weather events on fish species, processing operations, and dependent communities. Species such as Scomber australasicus, Gazza minuta, and Secutor insidiator were identified as the most vulnerable, with SST exposure emerging as the primary driver. Sectoral analysis revealed that drying and smoking operations face the highest vulnerability due to their reliance on weather- dependent traditional methods, limited infrastructure, and constrained financial and market resources. In contrast, canning and bottling sectors demonstrated lower vulnerability, supported by advanced technologies, controlled processing environments, and access to robust institutional and financial resources. Regional analysis highlighted elevated vulnerability in provinces like Masbate, Leyte, and Samar due to high exposure, while Western and Central Visayas exhibited sensitivity-driven vulnerabilities. These findings underscore the interconnectedness of ecological and socio-economic risks and provide a framework for addressing sector- and region-specific vulnerabilities. By aligning adaptation strategies with localized needs and systemic challenges, this study contributes to fostering resilience, sustainability, and competitiveness in the Philippine fish processing sector amidst evolving climate challenges.
