Leveraging marine geospatial data to optimize fad placement for enhancing north gorontalo's coastal economy

Abstract

This study explores how marine geospatial data can optimize Fish Aggregating Device (FAD) placement to balance sustainable fisheries and economic benefits for North Gorontalo's coastal communities. In the Sulawesi Sea, part of Fisheries Management Area 716, FADs boost fish catches but risk overfishing and environmental harm if poorly managed. Issues like FADs being lost to strong currents, such as the "knife current," further complicate their use. This research employs geospatial tools, including ocean current modeling, potential fishing zone analysis, sea depth evaluation, and restricted zone identification, to recommend optimal FAD locations. It also assesses the economic impact of FADs on local communities. The methodology integrates spatial and ex-ante analyses, using data from on-site surveys and hydrodynamic modeling to classify FAD placement suitability into three categories: low (Class 1), medium (Class 2), and high (Class 3). Findings reveal 5 FADs in low-recommendation areas, 27 in medium, and 6 in high-recommendation zones. The study highlights that FADs significantly support the local economy, with pelagic fish constituting 83.37% of the 2021 catch (21,535,604 kg). By adhering to regulations and leveraging geospatial insights, optimal FAD placement can minimize losses, enhance yields, and sustain long-term economic benefits for North Gorontalo's coastal communities. The discussion emphasizes aligning FAD deployment with fishery potential and regulatory compliance to ensure sustainability
