Effect of orally administered azadirachtin on non-specific immune parameters of goldfish Carassius auratus (Linn. 1758) and resistance against Aeromonas hydrophila

► Azadirachtin (AZA) EC 25% modified non-specific immunity in Carassius auratus. ► 0.1-0.4% (AZA) fed groups showed gradual increase in haemato-immunological response. ► Dietary incorporation of Azadirachtin @ 0.4% enhances survival against A. hydrophila. ► Azadirachtin plays immunostimulatory role in C. auratus.
