Abstract: Performance test of bigeye tuna ( Thunnus obesus ) potential fishing ground (PFG) in South of Java Indian Ocean (SJIO) has been conducted. The input data of this study were sub-surface temperature of Copernicus Marine Environment Monitoring Service (CMEMS) at a depth of 180 m and Argo Float at a depth of 200 m. PFG of bigeye tuna was developed by applying empirical cumulative distribution function (ECDF) analysis. Validation of PFG was done by applying quantitative method. A total number of 1,311 sample location of fish catchment during 2013 were overlayed with PFG map. The results show that the regions with high density of PFG were distributed around the latitudes of about 10°S to 17°S, with preferred temperature between 14.5°C and 17.5°C. Accuracy of CMEMS PFG and Argo Float PFG were 87.2% and 83.7% respectively. Based on the result of the analysis, it can be concluded that both of CMEMS and Argo Float sub-surface temperature shows a high performance.
