The present study was carried out to evaluate the immunostimulant potential of Amla (Phyllanthus emblica). Formulated diets with different concentrations of ethanolic extract of P.emblica (D1=0%, D2=1% and D3=2%) were fed to T.mossambicus for 40 days, the Specific Growth Rate (SGR), Feed Conversion Ratio (FCR) were calculated and significant increase was observed in SGR & FCR. The experimental fishes were infected with Pseudomonas aeruginosa and after 5 days the haematological parameters like Total Erythrocyte count (TEC), Haemoglobin (Hb), Total leucocyte count (TLC), Differential leucocyte count (DLC), serum total protein, serum albumin and globulin levels were analyzed. The TEC, Hb, TLC, Lymphocytes, Neutrophils and monocyte counts increased significantly in D3 diet fed fishes. Highly significant increase was observed in serum total protein and albumin levels in fishes fed with D2 diet and increase in Globulin levels were insignificant. Basophil and Eosinophil counts decreased significantly. Thus P.emblica in fish feed preparations may be included as growth promoter and immunostimulator.
