The composition of oils were analysed using GC/MS. Antibacterial effects of essential oils against <i>V. salmoninarum </i> were detected by agar diffusion and tube dilution assays. Thyme (125 μL ml <sup>-1 </sup> MIC) and clove (500 μL ml <sup>-1 </sup> MIC) essential oils were shown to possess strong antibacterial activity against <i>V. salmoninarum </i>. The main components of effective essential oils were carvacrol (63.57 %) and eugenol (85.99%), respectively. As a result, these two plant species that tested against <i>V. salmoninarum </i> which is causative agent of vagococcosis can be used as an antibacterial agent. For this purpose, in vivo antibacterial activities against vagococcosis of thyme and clove essential oils should be explored in the further studies. </span> </p> <hr /> <p style="text-align:justify;"> <span style="font-size:14px;"> <br /> </span> <br /> </p>}, number={2}, publisher={Ege University}, organization={Suleyman Demirel University, Scientific Research Project Grant.}
