The sangkuriang catfish (Clarias gariepinus) is one type of freshwater fish that has high production value. The current problem related to the growth of catfish (C. gariepinus) seeds is less than optimal so it does not reach the required production target. Therefore,additional nutrition is needed from commercial pellets combined with the use of earthworms (Lumbricus rubellus). This study aimed to determine the effect of combined feed of commercial pellets and earthworms (L. rubellus) on efforts to improve feed efficiency, growth and survival rate of sangkuriang catfish fry  (C. gariepinus). The research  used was experimental method, starting from the preparation of  fish rearing containers, acclimatization and stocking of fish fry, rearing  and treatment harvesting, and data analysis. There were  two treatments used, namely P₀ (commercial pellets) and P₁ (commercial pellets 25% and earthworms 75%).  Variables observed included growth, survival rate, and feed efficiency.  The results of the study showed that the absolute length growth, absolute weight growth, survival rate and feed efficiency of sangkuriang catfish (C. gariepinus) fry was better in P₁ with using commercial pellets combined with earthworms (L. rubellus) (P₁). Feeding a combination of commercial pellets and earthworms (L. rubellus) in the right way affects better growth, higher feed efficiency, high survival and good water quality values to support the growth of sangkuriang catfish fry.
