After acclimation, fish (6.87 ± 0.21 g) were allocated into 12 aquariums (20 fish per aquarium). Basal diet were supplemented with 0 (control), 1.5, 3 and 4.5 g kg -1 MOS in a totally randomized design trial in triplicate groups. At the end of the trial (8 weeks), growth factors (final weight, weight gain, specific growth rate (SGR), food conversion ratio (FCR), and condition factor) and immune responses (serum Ig levels, lysozyme activity and alternative complement activity (ACH50)) were assessed. The results showed no significant differences in growth and feeding parameters between control and MOS supplementation diets (P>0.05). The highest and the lowest growth performances were observed in 4.5 g kg -1 MOS and control group (P<0.05). Subsequently, immune responses (Ig levels, lysozyme activity and ACH50) were significantly higher in 4.5 g kg -1 MOS fed fish (P<0.05). The survival rate of control group was lower than the MOS groups, but not significant (P>0.05). These results indicate that MOS at 4.5 g kg -1 of the diet can be considered as a beneficial dietary supplement for improving the growth performance and immune response of gibel carp juveniles.

Basal diet were supplemented with 0 (control), 1.0, 2.0 and 3.0 g kg -1 MOS in a totally randomized design trial in triplicate groups. The experiment carried out in 100 liters PVC tanks. 20 juvenile carp with initially average weight 1.3 ± 0.17 g were stocked in tanks and fed up a day. There were no significant differences in growth and feeding parameters between fish fed control and MOS supplementation diets (P>0.05). The highest and the lowest growth performance were observed in 1.0 g kg -1 MOS and control treatment, respectively. There were no significant differences in survival rate and body composition among experimental groups (P>0.05), but in group treated with 1.0 g kg -1 MOS showed higher protein carcass (P>0.05) than other group. An elevation of hematocrit, lymphocyte (P<0.05), WBC, RBC, Hb and eosinophil (P>0.05) were found in the fish fed diet 1.0 g kg -1 MOS. The result indicated that 1.0 g kg -1 MOS can improved growth performance, survival, final production and some blood parameters of carp juvenile and it is appropriate for supplementation in the diet of cultured juvenile carp.

Fish were divided into 4 groups before fed diet for 8 weeks with 0.5%, 1% and 1.5% ginger extract and with unsupplemented commercial diet as the control. Results showed that there was a significant different in weight gain in fish fed ginger extract diet compared to the control (P<0.05). There were no significant differences in condition factor, feed conversion ratios, specific growth rate and survival between juveniles fed control and ginger extract supplementation (P>0.05).
