Rice field eel (Monopterus albus) fish, often there is a failure in the process of and spawning. Rice field hormones Pregnan Mare Serum Gonadotropin (PSMG), human chorionic gonadotropin (hCG) and antidopamine (AD). maturation and determine the status sex completely randomized design (RAL) with seven treatments and seven as: Controls (0.95% NaCl of fish, AD 0.01 mg/kg of fish, PMSG 20 IU/kg+AD 0.01 mg mg/kg weight of fish. Aquarium used as many seven pieces with size cm. The result is best hormone combination treatme with hormone concentrations of estradiol 0.17 to 4.36%; HSI values maturity level TKG IV pregnancy rate 100%; contained in PMSG stimulates an increase FSH, estradiol caused performance of the enzyme aromatase process faster for 4 weeks, look at increasing GSI, H maturity, fecundity, body weight gain conclusion of this study is the induction of maturation eel rice can be done with PMSG 20IU+AD 0.01 mg/kg with a length of 22±2 cm results are females (mature) Keywords: Rice field eel, maturation, PMSG, hCG, antidopamine SUMMARY PUTRA. Hormonal Induction maturation of Rice albus). Guided AGUS OMAN SUDRAJAT and NUR are hermaphroditic protogynous. In the female final gonadal maturation, ovulation eel with a total length of 22±2 cm by inject This study aimed to induce gonadal of rice field eel. This study uses a reaply NaCl), PMSG 20 IU/kg weight of fish, hCG 20 IU/kg weight /PMSG 20 IU/kg+hCG 10 IU/kg weight of fish, mg/kg weight of fish, and hCG 20 IU/kg of treatment PMSG and antidopamin estradiol-17β 235.2 to 35.43 pg/ml; GSI values 2.07 to 3.52%; egg diameter 0.48 to 3.07 mm; gonad G IV; fecundity 128 eggs; length 0 cm; weights ; and sex status all female. This result because estradiol-17β concentration ormance so that affects vitellogenesis HSI, egg diameter, gonad was observed and sexual status injection for four weeks. Sex status of rice field eel and weight of about 5 g until 12 g hormonal induction mature).
