Abstract

This research examined the feeding rate optimization in TGGG (♀ tiger grouper × ♂ giant grouper) hybrid grouper cultivation. Feeding optimization is pivotal for cost efficiency in fish farming. This experimental research was conducted for 30 days using TGGG hybrid grouper fingerlings with an average size of 24.76 g (±1.67 g). Different feeding rates were applied in the treatments (4% fish biomass per day in treatment A, 5% in treatment B, and 6% in treatment C) with 2 repetitions of each treatment. Treatment A showed the best outcomes with the highest growth (WGR 38.0% and SGR 1.04% day-1), the most efficient FCR (i.e 3.69) and the highest BCR (i.e 1.08). To conclude, the optimal feeding rates include 4.10% fish biomass per day for BCR, 4.19% fish biomass per day for FCR, and 4.23% fish biomass per day for both WGR and SGR.
