An experiment was conducted to evaluate the survival and growth of Kryptopteruslais larvae given fed intact and processed T. tubifex. Fish larvae used in this experiment waslarval of Kriptopterus lais 7 days old, while initial mean weigh and length of larvae were 0,002 g and 0,7 cm, respectively. The experiment used in this study was the completely randomized design, with three treatments and three replications; P1 (intact T.tubifex); P2 (Minced T.tubifex), and P3 (T. tubifex in blender). The results showed that there was no significant difference across treatments for survival rate and growth rate of Kryptoterus lais larvae (P > 0.05). The highest survival rate (38.27%) was recorded in P1(intract T.tubifex). In Addition, the highest weight (0.513 gr) and length (3.93 cm) of K. lais larvae were also found in P1.
