Abstract
This study employs an output-oriented Data Envelopment Analysis (DEA) approach to evaluate the operational efficiency of the offshore handline fishery in Khanh Hoa province during 2023/2024. Findings reveal that the average operational efficiency of the sampled fleet is 0.79, indicating that output could increase by up to 26% without additional input if vessels operated at optimal efficiency. Analysis shows that vessel size negatively impacts efficiency, with large-capacity vessels (over 450 CV)—despite receiving the most state support—exhibiting the lowest performance. This inefficiency is primarily attributed to the labor force's technical skills falling short of operational demands. Therefore, policies supporting the expansion of large-capacity offshore vessels must be integrated with strategies to enhance the skills and competencies of the fisheries workforce to ensure sustainable development.
