In present investigation attempts had been made to detect dietary effect of kiwi fruit on growth performance and immunology of Mystus vittatus Fruits are an important part of a healthy diet in our daily routine. All the fishes were put in portable plastic pools   each portable plastic pools   stacked with 10 infected fish averaging 11.60 ± 0.80 g and those were fed at maintenance level for 60 days prior to the experiments.. the pathogens were isolated, characterized and identified as Aeromonas sp.,Escherichia coli, Edwardsiella sp. Mycobacterium sp and Vibrio sp.. The various concentration of soxlet extract of kiwi fruit was used as 20 ml/kg,(Dk-2) , 30 ml/kg (Dk-2), 50 ml/kg (Dk-3). 60 ml/kg(Dk-4) and Dk-1 as control. These feeds selected for further antagonistic activity against all the pathogens by formation of zone of inhibition..
