<![CDATA[AbstractResearch on the effect of feeding frequency and feeding rate on growth, feed eficiency and survival rate of java barb larvae (Puntius javanicus Blkr) was conducted on 26 June-4 August 2018 at the Fish Hatchery and Breeding, Pinang Mancung Tebing Tinggi, North Sumatra. In this research the larvae were rearing in aquarium sized 40x30x30 cm filled with 15 L of water. Each aquarium was stocked two larvae per L.The experimental design useda completely randomized design (CRD) with two factors, namely feeding frequency with three levels: two times/day (F2), three times/day (F3) and four times/day (F4). The second factor was the feeding rate with three levels: P25 (25 %of body weight), P50 (50 % of body weight), P75 (75 % of body weight).To minimize errors, each level of treatment was repeated 3 times. The best growth rate in the treatment of F4P75 (feeding frequency four times/day with feeding rate 75% of body weight)with an absolute weight of 2.45 gr, absolute length 3.45 cm, average growth rate of 14.78 %/day, feed eficiency 24.56 % and survival rate 98.88 %. The condition of water quality is the water temperature 24,6-27,90C, pH 5,3-6,7 and dissolved oxygen 5,1-6,0 mg/l.
