Abstract:
Diazinon is one of the organophosphate toxins which has destructive impacts on skin and tissue in fish due to having high stability and low solubility in water. Farm fish are exposed to these toxins, since water wastes are not filtered after exiting. Aloe vera is pharmaceutic plant with anti-inflammatory and immune stimulant effect. This research was conducted to evaluate the short-term effect of Aloe vera on rehabilitate the tissue of common carp damaged by sub-lethal diazinon concentration. For this intent 90 carps with initial mean weight of 45.2±6.05 were divided into 9 aquariums. Sub-lethal diazinon concentration was applied at concentration of 0.5 mg/l. Treatments were including 1) diet containing 5% crude Aloe vera 2) Aloe vera 10% bathing 3) control (without Aloe vera) and each treatments were in 3 replicates. Results of the blood parameters including red blood cell, white blood cell and hemoglobin showed significant differences between treatments (P<0.05) But there were no significant differences in hematocrit, MCV, MCH and MCHC (P>0.05). Higher value of red blood cell, white blood cell and hemoglobin was observed in the Aloe vera bathing fishes but control fish was lowest among treatments. Histopathologic results showed hyperplasia in primary and secondary gill filaments, shortening the gill filaments and secondary gill base swelling in fish fed diet 5% of Aloe vera. Also hyperemia was observed in Aloe vera bath treatment. Generally it seems that, Aloe vera bath treatment had the better influence on recovery of tissue and blood factors improvement.
