Abstract

The quality and availability of seeds are the main problems in tilapia cultivation. One of the parameters that can be used to evaluate the quality of tilapia fish seeds is the RNA/DNA ratio. This research analyzes the influence of feeding Daphnia sp. enriched with amino acids on RNA/DNA performance in tilapia fish larvae. This research was carried out at the Nutrition Laboratory of the Aquaculture Study Program, Bosowa University, Makassar. RNA/DNA ratio analysis was carried out in October 2023 at the Takalar Brackish Water Aquaculture Fisheries Center Test Laboratory.  This research used a Completely Randomized Design (CRD) with four treatments and three replications as a quantitative experimental method. The treatments are : A (Daphnia sp. + amino acids 1 mL/liter); B (Daphnia sp. + amino acids 3 mL/liter); C (Daphnia sp. + amino acids 5 mL/liter) and D (Daphnia sp). The results showed that providing Daphnia sp. enriched with 3 mL/liter amino acids can increase tilapia larvae's RNA/DNA ratio, which amounted to 0.866. This research helps increase the availability of quality tilapia seeds.
