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), but did not give a significant effect on the survival rate of Nirwana tilapia fingerlings (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. © Published under licence by IOP Publishing Ltd.
