BACKGROUND: Medicinal plants have a long history in the treatment of parasitic diseases and are usually free of side effects. Removing and killing tomonts and theronts of this parasite can prevent the parasite pathogenicity in fish. OBJECTIVES: The present study aimed to investigate the inhibitory effect of ethanolic extract of Zataria multiflora on both free and parasitic life stages. METHODS: Three soluble forms of Zataria multiflora extract (80 ml/L) were prepared, which contained freshly prepared solution, stored solution at room temperature for one month and stored solution at refrigerator for one month. Afterwards, different dilutions were prepared for each of the solutions and the tomonts and Theronts were treated with different dilutions of the extract. RESULTS: Zataria multiflora extract can kill all theronts at concentrations of 20 ml/L during 6.04 to 6.37 min and concentration of 10 ml/L during 31/2 to 32.4 min, respectively. However, at these concentrations, only 3.46-6.11 % of tomonts were killed herein after 4 hours. CONCLUSIONS: Tomonts were found to be more resistant to the parasiticides than theronts. The use of Zataria multiflora extract significantly reduced tomont reproduction and decreased Ich infectivity prevalence and intensity. Zataria multiflora extract prevented Ich infestation in naive fish and effectively treated infected fish.
