Abstract

This study aims to examine the effect of adding carotenoids from red dragon fruit skin in the feed on the quantity and activity of chromatophore pigment cells in koi fish. The research employed a Completely Randomized Design (CRD) with four treatments of carotenoid doses from red dragon fruit skin (0, 1500, 2000, and 2500 mg/kg of feed) and three replications for each treatment. Koi fish were maintained for 60 days in twelve glass aquariums measuring 50x40x45 cm, each equipped with a filtration system. The results showed that the 2500 mg/kg feed dose resulted in the highest number of chromatophore cells in koi fish. Carotenoids from red dragon fruit skin can be used as a feed supplement to enhance the characteristics and brightness of koi fish color at a dose of 2500 mg/kg of feed.
