Abstract
This research was conducted in the Hatchery Building 4 Faculty of Fisheries and Marine Science, Padjadjaran University. The implementation started from July to September 2023. The purpose of this study was to test the growth performance of G6 transgenic mutiara catfish by feeding commercial feed containing different proteins to induce growth rate and protein use efficiency. The treatment design used the complete randomized design (CRD) method with four treatments (A: 39% feed protein; B: 32% feed protein; C: 20% feed protein; and D: 37% feed protein (mixture of pindang tongkol and PF.1000)) with three replications. Data were analysed using Sigmaplot 15.0 for absolute weight gain (Wg), feed conversion ratio (FCR), protein retention (RP), and protein productive value (PPV) and using Duncan Multiple Range Test (DMRT) with 95% confidence level. The results showed that treatment A gave the best results on the value of Wg (average weight gain of 4619 g ± 344.3 g) and the lowest FCR (0.63 ± 0.058), and the best protein retention and PPV values were shown in treatment B, as follows 19.24% and 17.4%.
