This research aims to determine the effect of providing rough fish and pellets with optimal dosages on the Giant Trevally culture to produce the highest growth in Pangandaran floating net cages. This research was conducted in August 2019 to September 2019 with 60 days fish rearing. The method used in this study was a Completely Randomized Design (CRD) with five treatments and three replications. The treatments were A (0% rough fish and 100% pellets), B (25% rough fish and 75% pellets), C (50% rough fish and 50% pellets), D (75% rough fish and 25% pellets) and E (100% rough fish and 0% pellets). The effect of each treatment was tested by analysis of variance (ANOVA) F test at an interval of 5%; if there were significant differences then followed by Duncan's multiple range test. The parameters observed in this study included fish survival (SR), Daily Growth Rate (LPH), Feed Efficiency (EPP) and water quality at the study site. The results obtained from this study were the provision of rough fish in Giant Trevally was able to increase the Daily Growth Rate (LPH) and the Efficiency of Feeding (EPP) for Giant Trevally. The highest growth value in this study was in treatment E (with 100% rough fish and 0% pellets) with LPH of 3.01%, total weight of 109.47gr and EPP of 30.60%.
