This study aimed to examine the effect of Gamal leaves flour supplementation in commercial feed on the growth of Nirwana tilapia ( Oreochromis niloticus ) fingerlings. The experimental design used was a non-factorial completely randomized design consisting of four treatments and four replications. The treatments studied included commercial feed without supplementation of Gamal leaves flour as a control (P0), commercial feed with supplementation of Gamal leaves flour 10% kg −1 feed (P1), commercial feed with supplementation of Gamal leaves flour 15% kg −1 feed (P2), and commercial feed with supplementation of Gamal leaves flour 20% kg −1 feed (P3). Nirwana tilapia fingerlings were stocked at a density of 1 fish L −1 . Nirwana tilapia fingerlings size ranges from 2-3 cm. Nirwana tilapia fingerlings maintenance period lasts for 40 days. The Annova test showed that the treatment gave a significant effect on the weight gain, length gain, daily growth rate, and feed conversion ratio (P 0,05). The best dose to increase the growth of Nirwana tilapia fingerlings was commercial feed with supplementation of Gamal leaves flour 10% kg −1 feed.
