Abstract
Description
Brightness of color is one of the factors that goldfish are in demand by the public. Feed containing carotenoids can affect the color pigment of fish. This study aims to determine the effect of the combination of Spirulina sp flour and Earthworm flour on color brightness and growth of goldfish. The method used is an experiment with a completely randomized design (CRD) which consists of 4 treatments with 3 replications. Treatment A (without the addition of flour), B (2% Spirulina flour, 10% Earthworm flour), C (4% Spirulina flour, 12% Earthworm flour), D (6% Spirulina flour, 14%). The results showed that treatment C had an effect on increasing the color of goldfish with an average value of 9.19, followed by treatment D with a value of 8.63, treatment B with a value of 7. 52 and treatment A with a value of 6.30. This study shows that the addition of a combination of Spirulina flour and Earthworms can increase the color of goldfish.
