Abstract

This study discusses the management of tuna (Thunnus spp.) fisheries in the Indonesia Fisheries Management Area (IFMA) 714, with a focus on the waters of Maluku Province during the 2020–2024 period. The study aimed to analyze the management of yellowfin tuna (Thunnus sp.) fisheries in the waters of Maluku Province within IFMA714. A quantitative descriptive method was employed using secondary data obtained from the Statistics Data Portal of the Ministry of Marine Affairs and Fisheries (MMAF). The analyzed data included tuna production, the number of fishing vessels, and dominant fishing gear types. The results showed that tuna production fluctuated throughout the observation period, increasing in 2021, declining in 2022 and 2023, and then increasing significantly again in 2024. These fluctuations were influenced by oceanographic conditions, climate change, weather conditions, fishing intensity, operational costs, and market demand for tuna commodities. The number of fishing vessels also changed from year to year, reflecting the level of tuna resource utilization in the Maluku region. In addition, the dominant fishing gear shifted from trolling lines to handlines in 2024, indicating a transition toward more selective and environmentally friendly fishing practices. The findings suggest that sustainable tuna fisheries management through the control of fishing intensity, the use of environmentally friendly fishing gear, strengthened monitoring, and data-based management is essential to maintain tuna resource sustainability while supporting the long-term economic viability of fishing communities in Maluku Province.

Abstract

The mangrove ecosystem of Bengkalis Regency serves as a critical habitat for the mud crab (Scylla sp.). However, intense exploitation pressure and habitat degradation driven by anthropogenic activities threaten the sustainability of this crustacean stock in the wild. The aim of this study was to analyze the biological characteristics of mud crab (Scylla sp.) populations, evaluate the sustainability status of mud crab resources in the mangrove coastal area of Bengkalis Regency, and formulate adaptive management strategies to support sustainable fisheries management. The research was conducted from April to May 2025 using secondary data from the Ministry of Marine Affairs and Fisheries of Indonesia and relevant scientific publications. A Systematic Literature Review (SLR), meta-analysis, and Rapfish-MDS approach were employed to assess the sustainability status of mud crab (Scylla sp.) resources. using a Systematic Literature Review (SLR) and meta-analysis approach based on quantitative secondary data compiled from multiple scientific journals. The multi-dimensional sustainability status (ecological, economic, and socio-cultural dimensions) was adaptively evaluated using the Rapid Appraisal for Fisheries (Rapfish) technique based on Multi-Dimensional Scaling (MDS). Results and Discussion: Morphometric synthesis revealed that the S. serrata population exhibits a negative allometric growth pattern (b<3), indicating that carapace width growth is more dominant than weight gain due to moulting cycles and environmental conditions. The Rapfish analysis showed that the multi-dimensional sustainability index of the Bengkalis coastal area scored 45.3, classifying it under the Less Sustainable category. The economic dimension was identified as the primary vulnerability point with the lowest score (40.4), followed by socio-cultural (44.7) and ecological dimensions (48.7). Statistical validation proved robust, with Stress values of 0.14–0.17 and R2 of 0.94–0.96. Key leverage attributes identified include the fishermen's marketing system (RMS 8.1), ecotourism diversification (RMS 6.9), and the effectiveness of physical mangrove rehabilitation (RMS 1.1). Formulated adaptive management strategies include implementing silvofishery systems, enforcing catch-size regulations under Regulation of the Minister of Marine Affairs and Fisheries No. 12 of 2020, and strengthening Community Surveillance Group based on local wisdom.
