Abstract

Koi fish (Cyprinus carpio) is a freshwater ornamental fish that is popular with people today. The attractiveness of koi fish can be measured by its brilliant color and health or stamina. The brightness of color in ornamental fish can be improved by providing feed containing carotenoids. Carrots (Daucus carrota), pumpkin (Cucurbita moschata), sweet potatoes (Ipomoea batatas) and gumitir flowers (Tagetes spp.) Are some natural carotenoid sources that are thought to increase the brightness of ornamental fish. The purpose of this study was to determine the effect of the addition of natural pigments in feed on the brightness and growth of koi (C. carpio) seeds. This study used a Completely Randomized Design (CRD) with an experimental method of 5 treatments (P1, P2, P3, P4, P5) and 3 replications. P1 = ordinary pellet feed, P2 = addition of carrot flour, P3 = addition of pumpkin flour, P4 = addition of sweet potato flour, P5 = addition of gumitir flour. The results showed that pumpkin flour (P3) was the most effective ingredient in increasing the brightness of koi fish. The addition of pumpkin flour to the feed can also increase growth in weight and length. This value is the best value among all treatments.

Abstract

Pakan merupakan faktor yang memegang peranan penting dalam kegiatan budidaya ikan.Penelitian ini bertujuan untuk mengetahui persentase penggunaan eceng gondok yang optimal dalam pakan buatan terhadap pertumbuhan benih ikan nila. Penelitian ini dirancang dengan menggunakan metode Rancangan Acak Lengkap (RAL) yang terdiri dari 3 ulangan dan 3 perlakuan.Masing–masing perlakuan ditambahkan eceng gondok 10% (P1), 20% (P2), dan 30% (P3). Benih ikan nila memiliki kisaran berat 0,82-0,91 gram dan kisaran panjang 3,5-4 cm yang ditebar dalam akuarium (40x40x40) cm dengan jumlah benih yang ditebar sebanyak 15 ekor Ikan uji di beri pakan sebanyak 3% dari bobot biomasa dengan frekuensi pemberian tiga kali sehari, yaitu pukul 08:00, 02:00 dan 17:00 WITA. Pengaruh perlakuan pada penelitian ini menujukkan hasil yang berbeda nyata (P>0,5 terhadap berat mutlak, laju pertumbuhan berat harian, pertumbuhan panjang mutlak, dan laju pertumbuhan panjang harian. Perlakuan terbaik diperoleh pada perlakuan P1 dengan pertambahan berat mutlak 0,81±0.04 gr, laju pertumbuhan berat harian 0.65±0.03 %, pertumbuhan panjang mutlak 1 cm ±0.05, dan laju pertumbuhan panjang harian 0.23±0.01.
