Dynamics of Tuna Fisheries Associated With Fish Aggregating Devices (FADs) Landed in Sorong City, Southwest Papua Province
The unregulated deployment of fish aggregating devices (FADs) has intensified exploitation, disrupting the marine food chain and reducing fish stocks. Tuna production at Sorong Coastal Fishing Port and Klademak Fishing Port, Sorong has declined annually due to uncontrolled FAD placement. This study maps tuna FAD distribution, catch production trends, fishing seasons, and weight distribution of landed tuna in Sorong City. Data sources include tuna catch records (2019–2024), FADs positions from fishermen’s GPS waypoints, and weight data from KKP enumerators (January–December 2024). Analyses include catch per unit effort (CPUE), the Fishing Season Index (using the moving average method), and descriptive spatial assessments. The research findings reveal that FADs are predominantly concentrated in the waters of Northern Waigeo, Northern Papua extending to the Pacific Ocean, and the Seram Sea. The distance between FADs ranges from 1.35 to 17.4 NM, with 86.75% positioned within 10 NM. Notably, all FADs remain unregistered. Tuna CPUE declined by 18.63% (2019–2024). The peak fishing season occurs in January, March-May, and October, with moderate activity in February, June, November, and December, and a lean season from July to September. Large tuna (>16 kg) are primarily caught April–December, while smaller tuna (<16 kg) dominate January–March.
