Abstrak

Abstrak Penelitian dilakukan untuk mengetahui dosis vitamin E yang tepat dalam pakan buatan berbasis tepung ikan rucah dalam meningkatkan kematangan gonad ikan nila merah (Oreochromis niloticus). Penelitian ini menggunakan Rancangan Acak Lengkap dengan 4 perlakuan dan 3 kali ulangan. Perlakuan A (kontrol), perlakuan B (vitamin E 300 mg/kg pakan), perlakuan C (vitamin E 600 mg/kg pakan) dan perlakuan D (vitamin E 900 mg/kg pakan). Ikan uji yang digunakan adalah ikan nila merah sebanyak 120 ekor, dengan bobot ± 200 gram per ekor. Ikan nila merah sebanyak 10 ekor dimasukan kedalam bak pemeliharaan berukuran 1,5x1x1m. Pemberian pakan tiga kali sehari dengan feeding rate 3% selama 40 hari. Hasil penelitian menunjukkan bahwa penambahan vitamin E dalam pakan buatan (300 mg/kg pakan) memberikan pengaruh paling baik untuk meningkatkan kematangan gonad ikan nila merah. Nilai Indeks Kematangan Gonad (3,86 % ± 0,18) dan Tingkat Kematangan Gonad berkembang hingga TKG IV. Kata kunci: ikan nila merah, tepung ikan rucah, vitamin E, TKG, IKG Abstract The study was conducted to determine the exact dosage of vitamin E for increasing gonade maturation of red tilapia (Oreochromis niloticus). This research using completed random design with 4 treatments and 3 replications. Fish were threated by various of dosage of vitamin E (control; 300 mg/kg feed; 600 mg/kg feed; 900 mg/kg feed). 120 red tilapia averaging 200 g individual body weights were stocked in each of 12 tanks (1,5x1x1 m) filled with 900 L of water. Feeding rate 3% in three times a day for 40 days. The results showed that the addition of vitamin E (300 mg/kg feed) give best effect for increasing gonade maturation of red tilapia. Value for gonade somatic index (3,86 % ± 0,18) and gonade maturation rate improved on IV stage. Keyword : red tilapia, trash fish meal, vitamin E, TKG, IKG
