Abstract: The present study was conducted to evaluate the dose dependent bio fortification efficacy of methanolic extract of Triphala on Oreochromis mossambicus as reflected by growth parameters. (TD1=0.4 %, TD2=0.8 % and TD3=1.2 % Triphala) The specific growth rate (SGR), feed conversion ratio (FCR), feed efficiency rate and protein efficiency ratio, were assessed and documented in each terminations. Significant increase in SGR, optimum FCR, FER and PER were observed in Triphala supplementation group compared to control. FCR presented an inverse relation with SGR. . Significant increase in percentage of survival observed in Triphala fortified group after Aeromonas hydrophila infection compared to control. Hence present study confirmed that Triphala in fish feed preparations can act as growth promoter and immune booster.
