An experiment was conducted to observe the effect of commercial feeding, and trash fish feed supplement on cantang grouper fish growth in floating net cages at Situbondo, Indonesia. The method used in this experiment was designed with 4 treatments and 3 replications. Samples (26.49 ± 0.81 cm) were a stocking density of400 fish/cage and maintenance for 30 days. The treatments used were P0;commercial pellets, P1;100% beloso trash fish ( Saurida tumbil ), P2; 100% kurisi trash fish ( Nemipterus nematophorus ) and P3; mixed wasted fish; 50% beloso trash fish + 50% kurisi trash fish, with four replicates. The best treatment result is that P0 quantitatively has significant effect on feed growth, survival, and efficiency compared to other treatments; SGR (0.5618%), SR (85%), FCR (3.69), and EPP (27.08%) compared to other treatments. The best treatment result is that P0 quantitatively has significant effect feed on growth, survival, and efficiency feed utilization of cantang grouper ( E. fuscoguttatus-lanceolatus ) compared to other treatments.
