Abstract
Silver arowana fish, Osteoglossum bicirrhosum (Cuvier, 1829), is an ornamental fish originating from Brazil which has been popular among hobbyists. The increasing demand is not followed by an increase in fish production. To increase production, it is necessary to provide proper feed. The purpose of this study was to evaluate the production of arowana fish seeds by providing different natural feeds through growth and survival rate. This study was conducted using Completely Randomized Design (CRD). This study used 3 replications and 3 treatments (A: Tubifex sp., B: Chironomus sp., and C: combination of Tubifex sp. and Chironomus sp.). The length and weight results showed that treatment A had length of 0.45 cm, weight of 0.33 grams, treatment B had length of 3.36 cm, weight of 2.30 grams and treatment C had 1.65 cm, a weight of 1.28 grams. The survival rate showed that treatment A 60%,treatment B 100% and treatment C 67%. Based on these results, the natural feed of Chironomus sp. was very appropriate to increase the growth and survival rate of silver arowana fish seeds.
