Objective:To investigate the effects of powdered silver zeolite (SZ) on the in vitro growth of the fish pathogen Saprolegnia sp. <br> Methods: The antifungal activity of SZ was evaluated by determining the minimum inhibitory concentrations using two-fold serial dilutions of powdered SZ in a glucose yeast extract agar at 22 °C. The growth of Saprolegnia sp. on the SZ agar treatments was compared to that on SZ-free agar controls. <br> Results:The results showed that SZ had an inhibitory effect on the in vitro growth of the tested fungi. The minimum inhibitory concentration of SZ for Saprolegnia sp. was also calculated at 600 mg/L, which is equal to 0.06 percent. <br> Conclusions:SZ is a potential good candidate to replace teratogenic and toxic agents, such as malachite green in aquaculture systems.
