| Abstract | ||||
| A potential site for mackerel tuna fishing in Indonesian waters is the Banda Sea FMA 714. The primary factor that constrains the distribution and abundance of fish is oceanographic factors. This research aimed to ascertain the relationship between fish dispersion and sea surface temperature in relation to chlorophyll-a, and delineate suitable mackerel tuna fishing spots in the Banda Sea. The analytical results endorsed the utilization of the pelagic habitat index (PHI) study. The results demonstrated a notable association between the distribution of mackerel tuna and the ideal sea surface temperature range of 29.15 to 31.85°C, together with chlorophyll-a concentrations of 0.05 to 0.40mg/ m³.The designated fishing zones are firmly defined, with March and October identified as the peak months. Hotspots, defined by oceanographic preferences, correlate with the spatial distribution of possible mackerel tuna fishing sites, hence enhancing the probability of feeding. This research indicated that fishing strategies, management, and conservation in the Banda Sea FMA 714 can be improved through the spatial regulation of high-potential fishing areas. | ||||
