sustainable mud crab fisheries
In the mangrove-rich waters of Micronesia, we’re investigating nature-positive strategies to enhance both fisher livelihoods and ecological sustainability. In partnership with the Locally-Managed Marine Area Network and the Conservation Society of Pohnpei, this research combines bioeconomic modeling with local fishery data to evaluate “crab fattening” — a practice where juvenile mud crabs are raised to market size in controlled environments. By identifying key thresholds and testing management scenarios, we aim to provide evidence-based guidance that supports community well-being while protecting wild crab populations.
Distant Water FISHING
Distant water fleets (DWFs) — industrial vessels operating far from their home nations — pose growing challenges to the sustainable management of fisheries, especially in low- and middle-income countries. In partnership with the U.S. Agency for International Development, we’re examining the impacts of DWF operations on local food security, marine biodiversity, and coastal livelihoods across four key regions. Our research supports the development of transparent, equitable fishing access agreements by creating tools to evaluate licensing systems and governance structures, helping coastal nations protect domestic resources and promote sustainable ocean economies.
small-scale fisheries vulnerability
Vietnam’s small-scale marine fisheries support the food security and livelihoods of millions, yet face increasing pressures from climate change. In collaboration with coastal fishing communities, and with support from The Nature Conservancy, our research assesses how climate impacts affect fisher livelihoods and evaluates adaptation strategies — particularly livelihood diversification — that can strengthen resilience. Using network analysis and vulnerability assessments, we aim to identify pathways that preserve cultural fishing traditions while informing policy interventions to support Vietnam’s 1.8 million marine fishers in a changing climate.
Cultural fisheries restoration
In the U.S.-Affiliated Pacific Islands, the forktail rabbitfish holds deep cultural significance, particularly among Guam’s Chamorro communities. As catches decline, traditional fishing knowledge and practices risk being lost to future generations. In partnership with Guam’s Division of Aquatic & Wildlife Resources, our research evaluates whether catch-based aquaculture and restocking programs could help revitalize these culturally important fisheries. Using advanced population modeling, we assess how different management scenarios might support both the traditional juvenile (mañahak) and adult (hiteng kahlao) fisheries while honoring Indigenous methods and cultural practices.
