Abstract

ABSTRACTOsteochilus hasselti is found in the Tarai River that has been contaminated with organic pollution and it may affects the reproductive biology of the fish. A study aims to understand the reproductive biology of O. hasselti has been conducted. The fish was sampled 3 times, once/month, from November 2017 to January 2018.  Parameters measured were sex ratio, gonad maturity level, Gonad Somatic Index (GSI), fecundity and egg diameter. Results shown that there was 29 males and 49 females (sex ratio 1:2). Male has slimmer body, brighter color than those of the female. Genital papilla of the male was white, while that of the female was red. Size at maturity level in male ranged from 95 to 170 mm SL, while that of the females was 90 to 190 mm SL. The average GSI of male ranged from 1.61 to 8.51% while that of the females was 1.02 to 11.14%. The average fecundity was 65,451 eggs/female and egg diameter was 0.10 to 1.00 mm. Based on the size of egg diameter can be concluded this fish is total spawner. Keywords: Sex ratio, gonad maturity level, gonad somatic index, fecundity, total spawner

Abstract

ABSTRACT The study was conducted on 26-31 May 2018 at BBI Kurnia Indah Mahato Village KM 37 Tambusai Utara Rokan Hulu Regency. The purpose of this study was to determine the best dose of the effect of the combination of ovaprim and oxytocin hormones with different ratios for ovulation and hatching of fish eggs baung. The method used in this study is the experimental method. The treatments applied in this study were: P0 = Injecting with 100% ovaprim 0.5 ml / kg, P1 = Injecting with 25% oxytocin + 75% ovaprim, P2 = Injecting with 50% oxytocin + 50% ovaprim, P3 = Injecting with 75% oxytocin + 25% ovaprim, P4 = Injection with 100% oxytocin 0.7 ml / kg. The results of this study concluded that ovaprim can be combined with oxytocin to stimulate ovulation and hatching of eggs in baung fish (Hemibagrus nemurus). The best dosage was obtained in P2 treatment (50% ovaprim and 50% oxytocin) which resulted in the fastest latency time of 6 hours 31 minutes, the number of eggs stripping as much as 63 g / parent, and IOS value 3.17%, increase in egg diameter 0.343 mm, egg maturity increase 28%, fertilization value 68%, hatching value 71.3%, and survival value (SR5 days) of 77%. Keywords: Injections, Oxytocin Hormones, Ovaprim Hormones, Baung Fish ((Hemibagrus nemurus))
