Tuna is an economically important fish in Indonesia, particularly in Morotai Island Regency, where it is a leading commodity. Since 2017, local governments have focused on managing tuna fisheries. However, over time, and particularly due to the impact of the COVID-19 pandemic, tuna fisheries management has not been optimal. This highlights the need for a new management model to maximize the production of this valuable resource. The proposed management model emphasizes responsible and sustainable fisheries management, specifically through the ecosystem approach to fisheries management (EAFM). This research aimed to assess the sustainability status of tuna fisheries based on EAFM criteria in Morotai Island Regency. Data collection for this study involved gathering information for each criterion across the six EAFM domains, using both primary and secondary data. Primary data were collected through direct surveys at the research site, in-depth interviews with respondents, and focus group discussions. The respondents included fishermen, business owners, and stakeholders. Secondary data were sourced from relevant agencies. The sustainability status of ecosystem-based tuna fisheries was analyzed using the six EAFM criteria and assessed using the flag model. The findings indicate that the sustainability of tuna fisheries in Morotai Island Regency, based on EAFM criteria, falls within a medium to very good range. The implementation of EAFM can be effective while maintaining the status of fish resources, fishing technology, and economic factors. Additionally, there is potential to enhance criteria related to habitat and ecosystems, as well as social and institutional domains.
