Efektivitas Pemberian Astaxanthin Pada Peningkatan Kecerahan Warna Ikan Badut (Amphiprion ocellaris)
Abstract
Ikan badut (Amphiprion ocellaris) adalah ikan hias air laut yang memiliki nilai ekonomis tinggi karena warnanya yang menarik. Peningkatan kualitas warna ikan badut yang bersifat permanen diperlukan untuk mendapatkan harga jual yang terbaik. Metode alternatif yang digunakan untuk meningkatkan warna ikan badut adalah dengan menggunakan astaxanthin. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh astaxanthin pada peningkatan intensitas warna, sintasan dan pertumbuhan ikan badut. Metode yang digunakan adalah Toca Colour Finder Modified (M - TCF). Penelitian dilakukan dengan rancangan acak lengkap (RAL) dengan perlakuan penambahan astaxanthin sebanyak 0, 20, 30, 40 mg/kg pakan. Ikan badut dengan padat tebar 20 ekor dipelihara selama selama 60 hari dalam akuarium berukuran 40 x 40 x 40 cm. Hasil penelitian menunjukkan bahwa penambahan astaxanthin memberikan pengaruh terhadap peningkatan warna dan sintasan tetapi tidak berpengaruh terhadap pertumbuhan. Penambahan astaxanthin sebanyak 30 dan 40 mg/kg pakan memberikan pengaruh terbesar dalam intensitas peningkatan warna ikan badut. Perlu dilakukan perhitungan analisa ekonomi terhadap penggunaan astaxanthin dalam budidaya ikan badut.
