Efektivitas Penambahan Spirulina sp. Pada Pakan Terhadap Performa Warna dan Pertumbuhan Benih Ikan Koi (Cyprinus carpio)

Abstract

The purpose of study to analyze the effect of Spirulina sp. to feed on color perfomance and growth of koi fish (Cyprinus carpio), and to determine the appropriate dose Spirulina sp addition to the feed. The experiment using the Completely Randomized Design (CRD), consisted of four treatments and three replications. Each treatments added Spirulina sp 0%, 3%, 6%, dan 9%. Fish color measurements are carried out using a color meter modified Toca Color Finder (TCF). The Results of this study show that the addition Spirulina sp to the feed significantly influence on color level based, absolute weight growth, specific growth rate, and survival rate the koi fish (P<0,05), however not significantly influence on changes in the dimensions of red, changes in color brightness L*a*b, and total length growth the koi fish (P>0,05). Dose Spirulina sp 9% feed produce changes color level based, color brightness L*a*b highest koi fish
