The effect of zeolite (Clinoptilolite) and clove oil (Eugenia caryophyllata) on survival and water quality factors in term of transportation on rainbow trout (Oncorhynchus mykiss)

The effect of zeolite (Clinoptilolite) and clove oil (Eugenia caryophyllata) has assessed in this study to investigate survival, physicochemical water factors transportation of rainbow trout (Oncorhynchus mykiss). 13 fish with an average weight about 80 ± 4.4 in 10 liters reservoir with a dewatering volume equal to eight liters was stored randomly. In this study, it was performed, four treatments and three replications for each treatment including control, clove oil (25 parts per million), zeolite (concentration 14 g per liter) and clove oil (40 parts per million) +zeolite (14 g per liter) treatment and survival factors of the final fish and quality of transportation water reservoirs including (ammonia (NH3), ammonium (NH4+), the degree of acidity (pH), carbon dioxide (CO2) and water temperature in the interval of 0.00, 6.00, 12.00, 18.00 hours was measured. Survival rate in the control treatment experiment was 97.44 percent at last and 100 percent in the rest of the treatments. Ammonia value in treatments during the interval had significant difference (P<0.05), so that at the times of 12.00 and 18.00 hours, ammonia in zeolites and clove oil + zeolite treatments was less and it had significant differences with control treatment (P<0.05). Zeolites and clove oil + zeolite treatments had the lowest ionized ammonium and it did have a significant difference with other treatments (P<0.05). Carbon dioxide value of water in clove oil treatments at the time 12.00 and 18.00 hours was more than other treatments and it showed a significant difference (P<0.05). PH levels were lower in the zeolite treatment but it didn’t have a significant difference among treatments (P>0.05). in this study, the usage of zeolite material to improve transportation water quality but clove oil was not effective
