Ph.D. Thesis
Freshwater prawn, Macrobrachium rosenbergii was reared in experimental recirculatory aquaculture system for 60 days feeding mannan oligosaccharide (MOS) and beta-glucan supplemented diets to evaluate their effect on growth, survival, immune response and resistance to Aeromonas hydrophila infection. The basal diet (35% crude protein) was prepared and used in both the experiments, which were conducted in triplicate groups. In first experiment, juveniles of (0.86 ± 0.01 g) were fed with MOS incorporated diets at levels 0.0, 1.5, 3.0 and 4.5 g/kg. There was a significant difference (p < 0.05) observed in final weight and survival percentage in 1.5 g/kg group as compared to other groups. The significantly improved immune parameters and significantly higher resistance was observed to Aeromonas hydrophila in 1.5 g/kg group. The light microscopy of hepatopancrease revealed that there were no detrimental effects on tissues among the groups supplemented with MOS. The gut morphology showed significantly increased microvilli length, unification and absorptive area in 1.5 g/kg group as compared to other groups. In second experiment, juveniles (0.34 ± 0.01 g) were fed with beta-glucan incorporated diets at levels 0.0, 1.0, 2.0 and 3.0 g/kg. There was no significant difference (p > 0.05) observed in the growth parameters among the groups, however there was significant difference (p < 0.05) in survival in 1.0 g/ kg group as compared to other groups. The significantly improved immune parameters and significantly higher resistance was observed to Aeromonas hydrophila in 1.0 g/kg group. The light microscopy of hepatopancrease revealed that there were no detrimental effects on tissues in 1.0 g/kg group as compared to other groups. The gut morphology showed increased microvilli length, unification and absorptive area in 1.0 g/kg group as compared to other groups. The results indicate positive effect of dietary supplementation of mannan oligosaccharide (1.5 g/kg) and β-glucan (1.0 g/kg) in the culture of freshwater prawn, Macrobrachium rosenbergii juvenile. |
