Treatments applied Tubifex sp, Artemia sp and kutu air (Moina sp and Daphnia sp). Result indicated that the kind of natural food affected growth and survival rate of tawes larvae. The Tubifex sp diet provided the best result of growth rate 0.5475 g, daily growth rate 13,8 g, 32.3 mm in length and survival rate of 66,7%. The water quality parameters during the research were temperature 24,5-29oC, pH 6-7, DO 2,35-7,49 ppm, ammonia 0,33-2,61 mg/l.
