| Abstract | ||||
| This study aimed to identify the spatial distribution of Fish Aggregating Devices (FADs) within the fishing grounds of mini purse seine operations in the waters of Buru Regency, Maluku Province, and analyze the spatial relationship between FAD distribution, chlorophyll-a concentration, and sea surface temperature (SST) across different seasonal periods. A quantitative descriptive approach was applied, utilizing secondary oceanographic data derived from Aqua MODIS satellite imagery covering the period from December 2023 to November 2024. Chlorophyll-a and SST data were spatially analyzed using Geographic Information System (GIS) software and integrated with FAD coordinates obtained through field observations and interviews with 12 mini purse seine vessels, representing the entire population. The results indicate that FAD distribution remained consistently located from the northwestern to eastern waters of Buru Regency throughout the year, despite seasonal variations in environmental conditions. During the Southeast Monsoon (June–August 2024), chlorophyll-a concentrations peaked (0.22– 0.31mg/ m³), and SST values were relatively lower (27– 29°C) across most of the study area, indicating high primary productivity. Conversely, the West Monsoon and transitional seasons generally exhibited reduced productivity. However, fishers did not relocate their FADs, suggesting limited adaptation to oceanographic changes. The resulting spatial maps underscore that integrating oceanographic data with FAD distribution can serve as a foundational basis for spatial fishing zone policies and the sustainable management of small pelagic fish resources. | ||||
