The Philippine fisheries sector has been affected by the impacts of climate change. Vulnerability to climate change pertains to a natural system's ability to cope with the negative impacts of climate change, variability, and extremes. Vulnerability Assessment (VA) provides a framework for climate change impacts evaluation over a broad range of systems. Tools such as Fisheries Vulnerability Assessment Tool (Fish Vool) have been developed to do VA. The "giant squid" diamondback (Thysanoteuthis rhombus) fishery in the province of Marinduque is an essential source of food and livelihood in the area. However, its vulnerability to climate change impacts has not been assessed. In this study, the "giant squid" fishery in Gasan, Marinduque, was assessed using Fish Vool. Results revealed that overall climate change vulnerability of the fishery is high, where both sensitivity and adaptive capacity are medium while exposure is high. Overall, the study provided a better understanding of the "giant squid" fishery vis-à-vis climate change and provided information for future fisheries management and conservation in the province
