Abstract
This research was conducted at the hatchery building 4, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. The implementation starts from November to December 2022. This experiment aims to test the growth performance of the G5 transgenic mutiara catfish by providing low protein feed. The treatment design used the completely randomized design method with four treatments (A:39% feed protein; B:31% feed protein; C:14% feed protein for transgenic catfish and D:39% feed protein for non transgenic fish as comparison) with three replications. Data were analyzed using Sigmaplot 15.0 for test parameters absolute weight gain (Wg), feed conversion ratio (FCR), protein efficiency ratio (PER), and protein retention (PR) and using the Duncan Multiple Range Test (DMRT) at a 95% confidence level. The best treatment results for feed efficiency and protein efficiency were obtained in treatments A and B with values of 1.25 and 1.43 as well as 2.04 and 2.23. Transgenic mutiara catfish can grow on a low protein diet is a new finding from this study.
