Larvae were fed with experimental diets from the beginning of feeding until adult (adolescence) (average weight: 67.1 g, length: 4.5 cm). Different levels of inulin had no significant effect on rate survival (P<0.05). The results showed that diet containing 3 gr inulin significantly caused the best FCR in Zebra fish (P<0.05). By increasing the inulin diet during the experiment, specific growth rate increased. Body weight gain had significant differences (P<0.05) as the highest and the lowest were observed in treatment 3 gr of inulin and control, respectively. The highest Condition factor was observed in 3 gr of inulin and the loa fish diet can improve the performance of the growth indices (FCR, SGR and CF), and increase larvae survival and final biomass, also this prebiotic can be considered as a suitable supplement for Cyprinidae diet.
