Since its launch, USAID Oceans has been working in partnership with the Southeast Asia Fisheries Development Center (SEAFDEC) and the Coral Triangle Initiative for Coral Reefs, Fisheries, and Food Security (CTI-CFF) with the explicit goals of combating IUU fishing in Southeast Asia, improving the region’s capacity for building sustainable fisheries with enhanced management and regulatory frameworks, and addressing sectoral human welfare concerns. September 2019 marked the completion of the program’s fourth year—which will be its last full year of implementation, closing in May 2020. This Annual Progress Report provides an overview of the program and its accomplishments in the 2019 Fiscal Year, covering the period of October 1, 2018, through September 30, 2019.
