ABSTRACT
Our present study investigates the effects of Illicium verum enriched diet on growth performance, immune response and disease resistance in Catla catla fingerlings against Aeromonas hydrophila. Experimental groups, i.e., infected C. catla were fed with 5 g/kg, 10 g/kg and 15 g/kg of I. verum diet for a period of 30 days showed a significant increase in their final body weight (FBW) over control. There was a significant increase (p < 0.05) in total weight gain (TWG), specific growth rate (SGR), feed conversion rate (FCR), protein efficiency ratio (PER), condition factor (CF) and survival rate (SR) in 10 g/kg and 15 g/kg groups compared to control; also from 31 to 60 days these groups showed an enhanced (p < 0.05) complement activity, phagocytic activity, respiratory burst activity and lysosome activity. The experimental group fed with 10 g/kg of I. verum diet showed the least cumulative mortality rate (5%) compared to 5 g/kg (30%) and 15 g/kg (15%) experimental groups and in control (10%) and negative control (75%). Our present study highlights that challenged fish fed with the mid dosage of 10 g/kg showed a significant increase in overall growth performance, non susceptibility to diseases and tolerance against A. hydrophila in C. catla compared to other experimental groups including the group given with high dosage of 15 g/kg. Thus our results suggest 10 g/kg as the optimal dosage of I. verum that can be used to enrich the fish diet for a better performance and effective immunostimulation in commercially important C. catla for its sustainable culture and is reported for the first time.
