This study aims to determine the effect of using alternative ingredients as a combination feed on the growth of catfish. This research was conducted in October - November 2020 which took place at the Laboratory of the Experimental Pond of the Departemen of Aquaculture, Sriwijaya University. The test fish used were catfish seeds measuring 5 - 6 cm. The study was designed with an experimental method in the form of a completely randomized design (CRD). The treatment to be used is a combination of commercial feed with alternative feed as many as 5 treatments with 3 replications, P0: commercial feed 100%, P1: combination of commercial feed 25% and alternative feed 75%, P2: combination of commercial feed 50% and alternative feed 50%, P3: combination of 75% commercial feed and alternative feed 25%, and P4: alternative feed 100%. Based on the results obtained, it shows that the use of alternative feed as a combination of feed has no significant effect on growth, feed efficiency and survival of catfish. The use of alternative feed as a combination feed of 50% (P2) has an effect on the growth and feed efficiency which is high in catfish of catfish. The growth of absolute length, absolute weight, and efficiency of fish feed produced were 1.67 cm, 4.20 grams, and 53.25%.
