Abstract

This study was conducted from May to October 2024 with the aim of analyzing the effect of Sea Surface Temperature (SST) and chlorophyll-a concentration (CHL) on the migration patterns of skipjack tuna (Katsuwonus pelamis) in Bone Bay, Luwu Regency. Primary data consisted of skipjack tuna catch data, geographic coordinates, and on-site SST measurements, collected by directly following fishing operations using fishing gear. Secondary data included satellite imagery from Sentinel-3 that included SST, CHL, and current velocity (CUR). The results showed that SST ranged from 29 to 31°C, with a significant relationship indicated by a p-value 0.005 and the lowest at 0.4 mg/m³. The best model based on AIC and CDE values was a combination of SST and CHL. However, partially, only SST had a significant effect on catches (p 0.05). This indicates that sea surface temperature is the most dominant oceanographic factor affecting fish catches.

Based on the CHL parameter, the most influential relationship was found at a concentration of 0.5–0.7 mg/m³ with a p-value &amp;gt;0.005 and the lowest at 0.4 mg/m³. The best model based on AIC and CDE values was a combination of SST and CHL.
