Abstract

This study aims to analyze the potential of Fishing Ground Zones (ZPPI) in the coastal waters of North Bali using Sea Surface Temperature (SST) and chlorophyll-a concentration parameter. A descriptive quantitative and spatial approach was applied, utilizing Level 3 Aqua MODIS satellite imagery collected from January 2021 to January 2025. The analysis identified three zonation categories: potential zones (271.65 km²), less potential zones dominating most of the study area, and non-potential zones (50.1 km²). Although SST and chlorophyll-a are theoretically positively correlated with fishery productivity, linear regression tests revealed a very weak relationship, with the highest R-squared value of only 0.092 in 2024, suggesting that other oceanographic factors — such as Indonesian Throughflow dynamics and terrestrial nutrient runoff — play a more dominant role in driving chlorophyll-a variability in this region. Spatial distribution of potential zones is concentrated in strategic coastal areas near small island clusters and entirely within the 12-nautical-mile boundary, making them accessible for small-scale fishers. This study contributes a remote-sensing-based spatial dataset of ZPPI that can serve as a reference for sustainable coastal resource management planning in North Bali.
