The Effect of Giving Various Natural Sources of ß-Carotene to Increased Color Intensity on the Oranda Goldfish (Carassius auratus)

This research aims to examine the effect of adding various sources natural ß-Carotene obtained from sweet potato flour, carrot flour and pumpkin color brightness Goldfish. The was carried out December 2021 February 2022 at Aquatic Animal Physiology Laboratory Building 2, Faculty Fisheries Marine Sciences, Padjadjaran University. experimental design used in this study a completely randomized (CRD) with five treatments three replications. were negative control (A), positive (B), 10% (C), (D) (E). Maintenance treatment on test fish for 60 days. Parameters observed included using Toca Color Finder (TCF), growth, life, air quality (Temperature, pH, Dissolved Oxygen). results showed that addition carotene feed had an increasing Oranda Goldfish (Carasius auratus). highest value found E as source ß-Carotene, namely 3.2 head, 3.3 body 2.5 tail. Survival rate is 100%. water parameter values ​​are good condition growth survival goldfish. Based observations temperature ranged 24.2°C - 28°C, pH 6.88-7.62 Oxygen 5.8-8.0 mg/L.
