Abstract

Small-scale fisheries play an important role in supporting coastal livelihoods, including in Pangandaran waters. Skipjack tuna (Katsuwonus pelamis) distribution is strongly influenced by sea surface temperature (SST). This study aims to map the optimal SST range for skipjack tuna in 2024 and analyze its spatial–temporal dynamics as an indicator of potential fishing grounds. SST data from Copernicus Marine Service (0.083° resolution, monthly) were analyzed descriptively based on optimal temperature ranges from previous studies. Results show SST ranged from 26.21 °C to 30.02 °C with clear seasonal patterns. Suitable conditions occurred mainly in January, May, July, and August, particularly during the southeast monsoon associated with upwelling. SST can serve as an initial indicator for fishing ground identification but should be combined with other oceanographic parameters
