Immunomodulation by 'ImmuPlus (AquaImmu)’ in giant freshwater prawn, <i>Macrobrachium rosenbergii </i>(De Man)

Abstract

ImmuPlus, a polyherbal commercial formulation was used to modulate the immune system of commercially important giant freshwater prawn <i>M. rosenbergii. </i>The prawns were fed with basal diet supplemented with ImmuPlus @ 1g/kg feed for 4 weeks. Results showed that the phenoloxidase activity (PO), haemagglutination and lysozyme activities were significantly

elevated in ImmuPlus-fed prawn up to 3 weeks of feeding and declined after 4 weeks of feeding. The total protein level in ImmuPlus-fed prawn raised up to 2^nd week of feeding. Incorporation of ImmuPlus at the rate of 1g/kg feed in the diet of prawn for 3 weeks may be beneficial in raising the immune status of prawn.
