Abstract: (147 Views) |
| A total of 50 goldfish (Carassius auratus) infected Ichthyophthirius multifiliis, weighing between 20-35 grams were placed in two control and treated aquariums with a volume of 1×1×2 m3 aeration of water with temperature conditions between 25-28 ℃ and pH = 7.2 with appropriate and nutritional conditions. The treated fish were anesthetized using clove extract and their contamination levels were checked before the experiment. The experiment showed that with increasing lavender essential oil concentration and duration, the rate of trophont losses was higher, and this difference was significant (p<0.05). The experiment also showed that concentrations of 0.1 and 0.25 ml of lavender essential oil had good effects on larval mortality. When larvae were exposed to a concentration of 0.5 ml for 60 minutes, almost 100% of the parasite larvae were killed, and the difference was significant (p<0.05). The results of this study showed that lavender essential oil is effective in eliminating parasites on the external surfaces of goldfish. |
