Efektivitas Pemberian Spirulina Sp. dan Astaxanthin Dalam Pakan Terhadap Pertumbuhan benih Ikan Komet (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 growth of comet goldfish (Carassius
auratus) seeds. The method used in this research is 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 results of this study indicate that the addition
of Spirulina sp. and Astaxanthin in artificial feed had no significant effect on the length and
weight growth of comet fish fry (P>0.05). However, the highest growth in length and seed
weight of comet goldfish was achieved in a combination of 3% Spirulina sp. and 0.1%
astaxanthin in artificial feed.
