Abstract

Color is the esthetics value of ornamental fish providing a barometer of its economic value. Red rainbow fish (Glossolepis incisus, Weber 1907) is an Indonesian native species of ornamental fish, which has the esthetics value of beauty in color. Improving the color quality of the red rainbow fish can be done through enrichment of carotenoids in feed. This research that aims to improve color quality of the fish through the carotenoid source of shrimp head meal in the feed was conducted at Research Station for Ornamental Fish Culture. Research design divided to six treatments dosage of shrimp head meal in feed which were 0% (control), 2%, 4%, 6%, 8%, and 10%. The level of coloration of the fish was observed every 10 days by using the standard color Toka Colour Finder (TCF). The results showed that a higher dosage of shrimp head meal in the feed increases the color quality of red rainbow fish. Dosage 10% showed the highest increase of red color on the abdomen, red color on the fins, and green on the back of the red rainbow fish were significantly different from the others dosage.
