Pengaruh Kombinasi Penyuntikan Ovaprim Dan Prostaglandin F2 Α (Pgf 2α) Terhadap Ovulasi Dan Penetasan Telur Ikan Nilem (Osteochilus Hasselti Cv)
The study was conducted in March - May 2018 in the Laboratory of Fish Hatchery and Breeding, Faculty of Fisheries and Marine, University of Riau, Pek-anbaru. The purpose of this research was to determine the effect of combination ovaprim and prostaglandin F2 α (PGF 2α) on ovulation and hatching of nilem fish (Osteochilus hasselti C.V). The method used in this research was an experiment method with Factorial Completely Randomized Design (CRD) with one factor, five treatments and three replications. The treatment used in this research was an injection of combination ovaprim and prostaglandin F2 α (PGF 2α) i.e. P1 (Ovaprim 0,4 ml/ kg + 0,1 ml/kg body weight PGF2 α), P2 (Ovaprim 0,5 ml/ kg + 0,1 ml/kg body weight PGF2 α), P3 (Ovaprim 0,6 ml/ kg + 0,1 ml/kg body weight PGF2 α ), P4 (Ovaprim 0,5 ml/ kg body weight), P5 (0,1 ml/kg body weight PGF2 α). The best treatment combination ovaprim and prostaglandin F2 α (PGF 2α) in P2= Ovaprim 0,5 ml/kg + 0,1 ml/kg body weight PGF2 α) with latent time (7.05 hours), total eggs stripping (76 eggs/gr broodstock), egg diameter increment (0,0516 mm), egg maturity increment (13,3%), Ovisomatic index (6,93%), fertilate rate (90,66%), hatching rate (87,59%) and survival rate of 5 days (95,76%). The temperature range from 27-300C, pH 4-7, DO 3,21-5,22 mg/l.
