ANALISIS TINGKAT KECERAHAN WARNA IKAN PLATY PEDANG (XIPHOPHORUS HELLERI) MELALUI PENAMBAHAN ASTAXANTHIN DENGAN DOSIS BERBEDA PADA PAKAN KOMERSIAL
ABSTRACT: Platy sword fish
(Xiphophorus helleri) is one of ornamental fishes which are commonly raised.
The price of platy sword fish could decrease if they have fade coloration on
their body. One of solution to improve and maintain quality of the color is by
adding astaxanthine into its artificial feed. This study aims to analyze
effects of the astaxanthine addition in artificial feed on an increase of color
intensity of platy fish as well as to find optimal dose of astaxanthine. Fish
used to be tested is platy sword fish ( X. helleri ) with the total of 120
tails in which they have an average weight of 2,0 ± 0,06 g per fish.
Astaxanthine used in this study is obtained from PT. Indobeta Store Jakarta.
While feed used in this study is commercial pellet containing protein 30 % and
by adding astaxanthine based on the treatments, those are A treatment (0 mg
astaxanthine/kgfeed), B treatment (100 mg astaxanthine/kg-feed), C treatment (
200 mg astaxanthine/kg-feed ), and D treatment ( 300 mg astaxanthine/kg-feed ).
Observation of the color intensity was conducted in 6 weeks using TCF (Toca
Color Finder). The addition of astaxanthine into artificial feed with different
doses can influence on the increase of color intensity of platy sword fish (X.
helleri). Astaxanthine dose of 200 mg/kg feed is best dose for the increase of
color intensity of platy sword fish (X heller ).
