Waste of smoked fish processing still contains nutritious ingredients for fish feed. Aims of this research were to determine the effect of giving pellets from fish fumigation waste to the growth and proximate levels of fish. Dumbo catfishes that feed by recycled pellets and characterizing fungal content that might contaminate recycled pellets. Catfishes were grouped into five groups, and feed with a variation of smoked fish waste contents in pellets K.0 (Control), K.1 (0% of recycled waste), K.2 (30% of recycled waste), K.3 (60% of recycled waste), and K.4 (90% of recycled waste). Feeding and nourishment were performed for 30 days. Results indicated that K4 yields the highest yield of weight and length for catfishes with a length of 22.28±0.69 cm and weight 31.74±0.93 gr, in addition to the lowest FCR value 0.77.
