Modulation of Immune Response in Edible Fish against Aeromonas hydrophila

The present study was to obtain a basic knowledge of the hematology of Catla catla Post challenged with Aeromonas hydrophila. Fish were fed diets representing different supplementation levels of Aegle marmelos fruit extract. The various concentration of fruit extract was 10mg, 20mg, and 30mg per 100g for each diet of fish. Supplementation of experimental feed after seven days collected from serum in treated fish to hematological parameters and biochemical parameters were analyzed between control and experiment. The results of the challenge test suggest that the fishes fed with 30mg Aegle marmelos diet had better immunostimulatory activity compared to the control group. Thus, our finding confirms our concentration that Aegle marmelos is a growth promoter and immunostimulant.
