This study aimed to analyze the effects of astaxanthin in commercial feed on growth and color intensity of green swordtail fish, Xyphophorus helleri. A total of 150 green swordtail fish (Xyphophorus helleri) had an average weight of ± 2 g per fish was used. A Completely Randomized Design (CRD) was used consisting of five treatments and three replicates. The treatments were A (0 mg/kg), B (50 mg/kg), C (100 mg/kg), D (150 mg/kg), E (200 mg/kg). Observation of color intensity had done once every 10 days for four weeks using TCF (Toca Color Finder). The result showed that the addition of astaxanthin into commercial feeds with different doses has a significant effect on the skin color intensity of green swordtail fish (Xyphophorus helleri). Hence, the concentration of 200 mg/kg Astaxanthin had the optimum skin color intensity of green swordtail fish (Xyphophorus helleri).
Key words: Astaxanthin / skin color / Xyphophorus helleri
