Vulnerability Assessment of Pacific Whiteleg Shrimp (Penaeus vannamei) Farms and Vendors in Davao, Philippines Using FishVool

The impacts of climate change on shrimp aquaculture can vary widely and can have environmental and socioeconomic consequences. This study assessed the vulnerability to climate change impacts of selected small-scale shrimp farms of Penaeus vannamei and shrimpfish market vendors in the Davao region, the Philippines, using a modified Fisheries Vulnerability Assessment Tool (FishVool). Shrimp farmers and vendors were interviewed using two separate semi-structured questionnaires. A total of thirty-nine (n = 39) shrimp farmers and forty-eight (n = 48) market vendors from various market areas within the region were interviewed. Data regarding exposure (E), sensitivity (S), and adaptive capacity (AC) were collected following the FishVool parameters with modifications. Results revealed that the overall climate change vulnerability of the shrimp farmers was medium (M), where both exposure and adaptive capacity were low (L) while sensitivity was medium (M). In addition, the shrimp market vulnerability of the various sites examined revealed medium (M) scores for markets in Pantukan, Mabini, Tagum, Maco, Lupon, Davao City, and Digos, and high (H) vulnerability scores for the markets in Panabo and Sta Cruz. Overall, the study provided a better understanding of shrimp farming in relation to climate change impacts and vulnerability and provided information for future shrimp farm management, marketing, and climate change adaptation in the region.

Automated summary

This study assessed the vulnerability to climate change impacts of small-scale shrimp farms and shrimpfish market vendors in the Davao region, the Philippines. The results showed medium vulnerability for the shrimp farmers and varying vulnerability levels for different markets.
