Abstract: (27 Views) |
Background and Objectives: Tilapia farming is currently dynamic and expanding worldwide to provide a cost-effective source of animal protein for human communities. Iron plays a vital role in the biogeochemical cycles of the environment, and its main source for fish is through nutrition.
Methods: In this study, 120 tilapia fish with an average initial weight of 40-60 grams were randomly divided into 4groups with three replications. After acclimatization to environmental conditions, they were fed diets containing 0, 50, 100, and 150 mg/kg of iron nanoparticles for 8 weeks. At the end of the course, blood was also taken from the caudal vein while under anesthesia.
Findings: The results showed an increase in the total number of red blood cells, white blood cells, hematocrit percentage, hemoglobin concentration, and lymphocytes under the influence of iron nanoparticles, with a significant increase compared to the control group at the p < 0.05 level. Additionally, the liver enzymes of Nile tilapia following the replacement of iron nanoparticles in the diet, at a treatment dose of 150 mg/kg for 8 weeks, were reported to show a significant difference compared to the control group at the p < 0.05 level. Therefore, the use of iron nanoparticles improved the health and survival of fish without having a negative effect on the liver.
Conclusion: Improving hematological indicators creates better living conditions for this fish and has the potential to be an alternative source for iron deficiency. After completing the usual steps of studying the blood samples, liver enzyme tests were also performed. |
