This research was conducted in April - June 2018, held at the Laboratory of Aquaculture, Faculty of Agriculture, Asahan University. In this study using putak fish test fish that have gonad maturity level (TKG) III. The feed used is in the form of silk worms, tilapia seeds and commercial feed. feeding 3% of body weight with a frequency of feed 4 times a day. The maintenance of putak fish is carried out in tarpaulin ponds measuring 50 x 50 x 50 cm with putak fish 3 tails per container with a volume of water of 35 cm. Fish are kept for 21 days. Data analysis used ANOVA, the experimental design used a Completely Randomized Design (CRD) with 3 treatments and 9 replications. The treatments included treatment of different feeds with treatment of A (silk worms), B (tilapia seeds) and C (commercial feed). The ANOVA results showed that different feedings had a significant effect on the maturity of gonads of putak The results showed that gonad maturity and the highest growth of putak fish were found in treatment A (silk worms) with IKG value of 13.45%, Fecundity of 1231 grains with egg diameter of 3 mm, with a period of 11 days, with a daily growth of 3, 76 cm and daily weight of 5.59 grams.
