ABSTRAK
Ikan koi kohaku (Cyprinus carpio L) merupakan salah satu jenis ikan koi yang memiliki harga tinggi. Kecerahan warna merah ikan koi kohaku menentukan harga jualnya. Penelitian ini untuk mengetahui pengaruh penambahan Spirulina platensis in the diet dengan dosis berbeda (1, 3 dan 5%) terhadap kualitas warna merah koi kohaku. Hasil penelitian ini menunjukkan bahwa penambahan Spirulina platensis melalui pakan dapat meningkatkan kualitas warna pada ikan koi. Pemberian pakan berupa pasta yang diperkaya dengan Spirulina platensis sebanyak 1% selama 5 minggu menghasilkan warna merah lebih cerah dibandingkan perlakuan lainnya dan kontrol. Perubahan warna yang terjadi tidak diikuti oleh perubahan panjang bercak warnanya. Penambahan Spirulina pada pakan tidak berpengaruh pada pertumbuhan berat dan panjang ikan koi.
