THE EFFECTIVENESS OF SUPPLEMENTATION OF SPIRULINA SP AND ASTAXANTHIN WITHIN FEED TO COLOR QUALITY OF COMET FISH (CARASSIUS AURATUS)

Abstract

The purpose of this study was to analyze the effect of artificial feeding with the addition of a combination of Spirulina sp. and astaxanthin on the color quality of comet goldfish (Carassius auratus) seeds. The method used in this research was to apply a combination of dosages of Spirulina sp. and astaxanthin in artificial feed, namely 0% Spirulina sp.:0% Astaxanthin; 1% Spirulina sp.:0.1% Astaxanthin; 3% Spirulina sp.:0.1% Astaxanthin; and 5% Spirulina sp.:0.1% Astaxanthin. Experiments using a completely randomized design (CRD) consisted of four treatments and three replications, the color of the fish in each treatment was observed using a modified Toca Color Finder (TCF). The results of this study also indicate that the addition of 1% Spirulina sp. and 0.1% astaxanthin gave the best color to comet goldfish seeds.
