Status of Sustainability Tuna Fisheries Management in the Border Areas of Indonesia and Timor Leste in the Ombai Strait

The potential of tuna fisheries resources in the border area of Indonesia and Timor Leste in the Ombai Strait has provided benefits for fishermen. In order to ensure the creation of a balance between the availability of tuna fish resources and their use by fishermen, it is necessary to have sustainable tuna fisheries management in the border areas of Indonesia and Timor Leste. This research aims to assess the status of management sustainability, determine management driving factors and analyze management priority scenarios. Data analysis was carried out using Multiaspect Sustainability Analysis (MSA) with EXsimpro software. The sustainability of tuna fisheries management in existing conditions is classified as sustainable. The driving factors for improving tuna fisheries management consist of CPUE trends, range collapse of fish resources, fishing capacity, application of fish handling technology, local wisdom, fishermen's cooperation, savings ratio, fishermen's assets, community participation and fisheries improvement programs. The status of highly sustainable tuna fisheries management can be achieved through moderate scenarios and optimistic scenarios. Efforts must be made to improve the leverage factors for improving tuna fisheries management to achieve a highly sustainable management status.
