This study aimed to evaluate the potential of Lippia sidoides essential oil as a food additive for Cyprinus carpio koi carp in improving health parameters and resistance infection by Aeromonas hydrophila. A total 312 were divided into groups. Twenty-four animals lethal dose 50% (LD50) test group. The remaining 288 distributed 24 experimental units (n = 12) six treatments-Lippia0.250%, Lippia0.125%, Lippia0.063%, Lippia0.031%, alcohol, control-with four replicates each. fed thrice daily with 5% living biomass 55 days. At end period, five specimens collected from each treatment analyze intestinal tract's zootechnical performance, hematological analysis, microbiology. challenged A. hydrophila, mortality rate was monitored 100 Thymol component highest concentration (76.6%) L. sidoides. Fish Lippia0.125% had greatest post-challenge survival. Lippia0.063% showed increased those Lippia0.250% lactic acid bacteria intestine. Hematological analyses did not show significant differences among treatments. authors suggest new studies higher concentrations diet C. than used this study.
