Among the applications of medicinal plants, it is their use as antimicrobial agents. The objective of this study was to investigate the effect of some essential oils against an etiological pathogen Flavobacterium spp. responsible for several lost in rainbow trout, (Oncorhynchus mykiss) hatcheries, the strains used in this study were isolated from rearing tanks water and biofilm, identified as Flavobacterium spp. based on phenotypic, biochemical and enzymatic characterizations. A collection of eight essential oils were extracted, analyzed and tested for an inhibitory activity against the isolated strains, the effect on this bacterium has been demonstrated by the aromatogram method based on a screening of bacterial growth in a solid medium culture with disks containing essential oils. Our study’s results show that the chemical composition of the extracted essential oils play a crucial role in their antibacterial activity, which varies from 6 mm up to 34 mm as maximal inhibitory diameter.
