## Abstract
Abstract Understanding the relationship between hotspot areas and the distribution and abundance of Yellowfin Tuna ( Thunnus albacares ) in the Banda Sea is crucial for effective fisheries management and conservation efforts in the region. This study explored this relationship using a satellite-based analysis approach. We attempted to analyze remote sensing for sea surface temperature, salinity, and chlorophyll-a parameters using catch data in November 2020-2022 with a total of 275 fishing points. The research findings indicate that the total catch weight per vessel falls within the salinity range of 33.8-34 psu, sea surface temperature range 30-31ºC, and chlorophyll-a concentration range 0.08-0.25 mg m −3 . Hotspots for Yellowfin Tuna were obtained from the salinity fronts. The distribution of Yellowfin Tuna is mainly found within a distance e of 0-20 km from the salinity front, and this area is an excellent feeding area. These hotspots can serve as indicators of the movement patterns of Yellowfin Tuna. The results of this study are expected to provide valuable insights into the spatial dynamics of Yellowfin Tuna in hotspot areas in the Banda Sea, ultimately contributing to more informed fisheries management strategies and conservation efforts in the region.
