| Effect of ditary prebiotic inulin on growth performance, survival and body composition in Kutum (Rutilus frisii kutum) fry stage were investigated for 8 week in 2010. Fish with initially average weight 1.1 ± 0.82 g were randomly distributed into fiberglass tank (75 fish per tank). A commercial diet supplemented with inulin: 0 (control), 0.5%, 1.0% and 1.5% diet in a totally randomized design trial in triplicate groups. The result showed that inulin at level of 0.5% of diet had significience difference on growth performance including weight gain, food conversion ratio rate, final weight and intestinal lactic acid bacteria in comparison with other group (p<0.05). There was no significance difference in survival and body composition among the groups (p>0.05). The results of linear regression showed that there were a negative relationship between some growth indices and survival and supplementation level of inulin. Based on the present results inulin at dose rate of 0.5% could have a positeve affect growth and survival of kutum in culture. |
