Effects of Natural (Red Bell Pepper & Tomato) and Synthetic (Astaxanthin & Β-Carotene) Pigments on Flower Horn Fish (Cichlasoma Sp.) Blood Parameters

Objective: In this survey, we have checked the effects of natural (red bell pepper and tomato) and synthetic (astaxanthin and β-carotene) pigments on bloods factors of Flower horn (Cichlasoma sp.). Methods: Five treatments (three replicates/treatment) were employed. Fishes were separated in fifteen equal groups and were fed for eight weeks with diets containing10 g kg–1 red bell pepper and tomato and 100 mg kg-1 astaxanthin and β-carotene. At the end of trial blood samples were taken from 5 fish that caught randomize by cutting the caudal stem. Results: Results of blood factors showed there is significant differences between WBCs, RBCs, Hb, HCT and Lymphocytes between treatments (p< 0.05). The best result observed in treatment fed with red bell pepper. Between The factors of Monocytes and Neutrophils, there was no significant difference between treatments (p> 0.05). The results showed that the use of red bell pepper in diets for Flower horn is effective and profitable in its ration.
