Abstract :

AbstractPresent study was done in order to evaluate the effect of Bio-mos (Mannan Oligosaccharide) as a kind of prebiotic on growth and survival of juvenile wild carp. This research was designed a completely randomized design in four levels of 0, 0.2, 0.4 and 0.6% bio-mos and in four treatment with three  replicates. 35 carp juveniles with average weight of 10.8±0.4 gr. were stocked in each tank and fed during 8 weeks. The results of statistics analysis showed the positive effect of increasing level of bio-mos on some of the nutrition and growth indices like general weight (WG), special growth rate (SGR), condition factor (CF), and survival rate (SR) of wild carp. So that in the level of 0.6 % bio-mos, the amount of mentioned factors increased in comparison with other treatments. Results of this study showed that diets with 0.6 % supplementary bio-mos has effects on increasing of operation of growth and nutrition efficiency in wild carp. The results of chemical analysis of body composition did not show any significant differences between treatments. Also this prebiotic in level of 0.4 and 0.6 can be a suitable supplementary in the diet of wild carp.
