Pengaruh Penyuntikan Hcg (Human Chorionic Gonadotropin) Dengan Dosis Berbeda Terhadap Ovulasi Dan Penetasan Telur Ikan Lele Lokal (Clarias Batrachus Linnaeus, 1758)

One of the economically valuable walking catfish species in Indonesia is Clarias batrachus. Due to high exploitation, this species may be at risk, making cultivation necessary. One of the key aspects of cultivation is the success of spawning. One of the applications of spawning is the use of hormones, and hCG is a hormone commonly used in fish spawning. This study aimed to determine the best dose of hCG (Human Chorionic Gonadotropin) injection on ovulation and hatching of local catfish eggs (Clarias batrachus Linnaeus, 1758). This research was conducted for 7 days in October 2024 at the Fish Hatchery and Breeding Laboratory, Faculty of Fisheries and Marine Sciences, Riau University. The method used in this study was an experimental method using a completely randomized design (CRD) with one factor consisting of 4 levels of treatment with three replications. The dose of hCG (Human Chorionic Gonadotropin) injection used in this study is as follows: P1 = Ovaprim injection at a dose of 0.5 ml/kg body weight (positive control), P2 = hCG injection at a dose of 700 IU hCG/kg body weight, P3 = hCG injection at a dose of 900 IU hCG/kg body weight, P4 = hCG injection at a dose of 1100 IU hCG/kg body weight. The result of this research was that the best hormone administration was found in P1 (Ovaprim injection dose of 0.5ml/kg body weight of the mother), which resulted in a latency time of 360 ± 0.00 minutes, egg diameter of 2.01 ± 0.01 mm, egg maturity of 95%, FR 93.38 ± 2.41%, HR 85.14 ± 7.68%, and SR 100%. In the number of eggs ovulated, the best results were found in P4 (hCG injection at a dose of 1100 IU hCG/kg fish body weight) with 6,113.82 eggs.
