The effect of natural (Red bell pepper and Tomato) pigments on the variability in color of Flower horn (Cichlasoma sp.)

In this survey, we have checked the effects of red bell pepper and tomato as a natural pigments source on the skin color of Flower horn (Cichlasoma sp.). Distributed randomly 45 fish of Flower horn in 9 aquarium Equal to 5 fish per aquarium. The trial was continued for 8 weeks. The fish were fed diets including 10 g kg–1 Red bell pepper and Tomato powder. Total carotenoid quantity of the fish was determined spectrophotometrically at the end of the experiment. The significance of them was analyzed using One-way ANOVA analysis software Spss 18. As an outcome, There was a significant correlation between treatments fed diets containing red bell pepper powder with other treatments (P<0.05). Showed higher concentrations of carotenoids in Treatments fed with food containing red bell pepper powder (0.05 µg g-1). There was no significant difference between treatment fed tomato powder and control treatment (P>0.05).
