Pengaruh Dosis recombinant Growth Hormone (rGH) yang Berbeda ke Pakan Terhadap Pertumbuhan dan Kelangsungan Hidup Benih Ikan Kakap Putih (Lates calcarifer)

This study aims was to determined the effect of rGH and the best dosage of rGH on the growth and survival of white snapper juvenile. This research was conducted on September to October 2019 for 43 days which was held at the Department of Marine and Fisheries Resources Control, Bintan Islands, Riau Islands. This research was used completely randomized design (CRD) methode with 4 treatments and 3 replications. Data was analysed with One-Way ANOVA, the results showed that the rGH hormone gave effect on white snapper juvenile, where the best treatment was on treatment C with rGH hormone 10 mg / kg of feed which where absolute weight growth value was 27.74 g, daily weight growth rate was 0.55 g , absolute length growth was 2.47 cm, daily length growth rate was 0.05 cm, Survival Rate was 95.55%, FCR was 3,64, and feed efficiency was 31,40%Penelitian ini bertujuan untuk mengetahui pengaruh rGH dan dosis rGH yang terbaik terhadap pertumbuhan dan kelangsungan hidup benih ikan Kakap Putih. Penelitian ini dilakukan pada bulan September sampai November 2019 selama 43 hari yang bertempat di Dinas pengawasan Sumber Daya Kelautan dan Perikanan, Kabupaten Bintan Kepulauan Riau. Metode yang digunakan ialah eksperimental dengan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. Menggunakan analisis data dengan One-Way ANOVA menunjukkan bahwa hormon rGH memberi pengaruhnya terhadap benih ikan Kakap Putih dimana perlakuan terbaik adalah perlakuan C dengan dosis 10 mg/kg pakan dengan nilai pertumbuhan bobot mutlak  27,74 g, laju pertumbuhan bobot harian 0,55 g, pertumbuhan panjang mutlak 2,47 cm, laju pertumbuhan panjang harian 0,05 cm , Kelangsungan Hidup 95,55 %, FCR 3,64, dan efisiensi pakan 31,40% %
