Pengaruh Penambahan Dosis Probiotik Yang Berbeda Dalam Pakan Terhadap Laju Pertumbuhan Dan Kelulushidupan Ikan Selais (Ompok Hypophthalmus) Yang Dipelihara Dengan Sistem Bioflok Pada Media Air Rawa Gambut

ABSTRACT

This research aim to determine the optimal dose of additional probiotic EM4 in feed to the growth performance and survival rate of Catfish (Ompok hypopthalmus) by using biofloc system on peat swamp water. This research was conducted on 40 days from June,13 to August 2, 2019 at Technical Service Unit (UPT) of Hatchery, Faculty of Fisheries and Marine, University of Riau. This research was using experimental method by completely random design (RAL) one factor with three replications. The treatments were: P1 (without EM4), P2 (EM4 10 mL / kg of feed), P3 (EM4 15 mL / kg of feed), P4 (EM4 20 mL / kg of feed). The material used probiotic EM4, molasses and peat water with a pH of 4. The results showed that a different doses of additional probiotic EM4 affecting the growth performance and the survival rate of catfish (Ompok hypophthalmus) using biofloc system on peat swamp water. In addition, it also affected the absolute weight growth, absolute length growth, feed efficiency and feed conversion ratio. The optimal dose was at 10 mL/kg of feed as it showed significantly different results compared to control and was not differ significantly at higher doses. So that while being applied in terms of economy, 10 mL/kg was the most efficient dose, by giving the an absolute growth of 8.64 g, growth of an average length of 12.93 cm, the specific growth rate of 8.57%, the survival rate was 100%, feed efficiency was 120.4% and feed conversion ratio 0.8.
