The effect of Red Paprika Extract (Capsicum Annuum) in Feed on the Color Intensity Level of Comet Fish (Carassius auratus)

This study aims to analyze the effect of red paprika flour in fish feed to increase the color intensity of the Comet fish juvenile. The research method used a Complete Randomized Design experiment consist of four treatments and three replicates. The treatments consisted of various levels of addition red pepper extract, namely treatment A (0%), B (3%), C (5%) and D (7%). The investigation includes color intensity of the fish. Survival rate and water quality parameters data were also taken. The color observation data were analyzed using the Kruskal-Wallis analysis, if there was a significant difference, the Z test was performed. The results of this study indicated that the addition of 5% red paprika extract to the feed was the best treatment with an increase in the color intensity level of comet fish at 4.71. While the comet fish Survival Rate (SR) data in all treatments were observed to be 100% and the water quality during the maintenance period was in the optimal range and met the standards. The average temperature value was 24.7-26.4ºC, DO 5.6-5.8 mg/L and pH 6.67-7.53.
