- Goldfish (Carassius auratus) is one of the freshwater ornamental fish commodities that have high economic prospects. To produce the growth and survival of an optimal goldfish larvae is required to provide quality natural feed. The natural food that has been commonly given for ornamental fish larvae is Paramecium, Rotifera, Daphnia, Moina, Artemia and Tubifex. Factors affecting the success of ornamental fish cultivation, one of which is the feeding appropriate to the mouth opening of larvae and nutritional content. The aim of this research is to determine the best type of natural food in improving the growth and survival of oranda goldfish larvae (Carassius auratus). This research was conducted for 28 days April until May 2017 at Botia Hatchery, Biological Laboratory and Water Quality Laboratory, Ornamental Fish Culture Research Centers Depok. The method of this study was experimental, using a complete randomized design (CRD) with 3 treatments and 4 replications. The fish larvae used were ± 5.7mm in length and weighed ± 1.2 mg. Fish larvae were given 3 kinds of feed treatment: A (Moina sp.), B (Artemia sp.) and C (Tubifex sp.). Parameters measured were the growth of absolute weight, the absolute length growth, specific growth rate, survival rate and feed efficiency. Water quality parameters were temperature, pH, DO and ammonia. The result showed that the used of silk worm as first feed for larvae indicated the best performances. The growth of the absolute weight of (1073.30±112.52 mg), absolute length of (28.08±0.70 mm), specific growth rate (24.26±0.38%) and feed efficiency (84.21±4.06%).
