In this experiment, golden rabbitfish (Siganus guttatus) were allocated between three treatment groups. The fish were injected with saline, human chorionic gonadotropin (hCG) and D‐Ala6, Pro9‐Net‐mGnRH. After injection, in 6 hr intervals, blood plasma samples were collected for steroid hormone (testosterone [T] in males and estradiol‐17β [E2] in females) using enzyme immune assay (EIA). In male fish, T levels significantly increased and reached 170 and 650 pg/ml for hCG and D‐Ala6, Pro9‐Net‐mGnRH treatments, respectively. Then T levels slightly decreased until 24 hr post injection. There were no significant changes of T levels in saline treatment. In female fish, we found significant changes in E2 levels at 2,567 and 524 pg/ml at 12 hr post injection in hCG and D‐Ala6, Pro9‐Net‐mGnRH treatments, respectively. No significant differences of E2 levels were observed in saline group. In the second experiment, we injected 100 golden rabbitfish with both hCG and D‐Ala6, Pro9‐Net‐mGnRH. Fish spawned successfully when hCG and D‐Ala6, Pro9‐Net‐mGnRH were given individually and in combination. Latency periods were between 46–64 hr with an average fertilization rate of 70%–90% and hatching rate of 56%–74%. The embryonic duration was 16–20 hr. The saline‐injected group produced no spawning. Our findings contribute to further understanding of exogenous hormones impact on golden rabbitfish reproductive endocrinology, refining breeding protocol and implications for fish propagation.

“…Hasil penelitian menunjukkan bahwa pemberian hormon Oodev pada pakan dapat meningkatkan pertumbuhan dari ikan giru yang diberi perlakuan. Diketahui bahwa Oodev merupakan produk hormon yang mengandung hormon GnRH dan antidopanim yang sering digunakan untuk pematangan gonad tahap awal pada ikan (Hoga et al 2018). GnRH merupakan neurohormon yang berperan dalam proses stimulus dan sintesis gonadotropin.…”

“…GnRH merupakan neurohormon yang berperan dalam proses stimulus dan sintesis gonadotropin. Pada vertebrata termasuk ikan, peningkatan serum gonadotropin dalam darah memberikan feedback positif terhadap sekresi Leptin dan Neuropeptida Y (NPY) yang diketahui berpengaruh dalam regulasi pertumbuhan somatik (Cortes 2012;Hoga et al 2018). Dalam penelitian ini tidak dilakukan pengukuran serum Leptin maupun NPY namun mekanisme kedua hormon ini dapat menjelaskan pertumbuhan yang terjadi pada ikan giru yang diberi perlakuan hormon Oodev.…”

“…Telah diuraikan bahwa hormon Oodev mengandung hormon GnRH yang berperan dalam stimulus dan sekresi hormon gonadotropin. Hormon Oodev juga mengandung antidopamin yang memberikan efek positif terhadap sekresi gonadotropin (Hoga et al 2018). Secara morfologi kematangan gonad dapat dilihat melalui penambahan bobot gonad akibat adanya perkembangan sel-sel gamet yang ada di dalam gonad (Cortes 2012).…”

Somatic growth and gonadal maturation play a crucial role in fish farming. To obtain high quality fries, broodstocks should be at the maturity stage of gonadal development and have precise body size. Widely used in fish farming, Oodev induces gonadal maturation as it contains pregnant mare serum gonadotropin and anti-dopamine that together actively affect gonadal maturation. Despite its popularity in fish farming, the effect of this hormone on the somatic growth and gonadal maturation of Amphiprion clarkii is not well understood. This research aims to determine the effect of Oodev mixed in fish feed on somatic growth and gonadal maturation of clownfish A. clarkii. The fish were treated for 30 days with three different levels of Oodev with a dose of 0 mL/kg, 0,5 mL/kg, and 1 mL/kg added in fish feed, designed in triplicate for each treatment. The results showed that treatment with 1 mL/kg Oodev had a more significant effect than control, increasing both length (0,9 cm in male and 0,7 in female) and weight (1,32 gram in male and 3,05 gram in female) of the treated fish. Similarly, the same dose had higher Gonadosomatic Index score than control with GSI of 0,47% (male) and 0,58% (female) higher than control respectively. In conclusion, the treatment with 1 mL/kg Oodev formulated ini fish feed showed the best effect on both somatic growth and GSI of A. clarkii. ABSTRAKPertumbuhan dan pematangan gonad memainkan peranan penting dalam budidaya ikan. Untuk memperoleh benih yang berkualitas, induk harus benar-benar matang gonad dan memiliki ukuran tubuh yang sesuai. Umum digunakan dalam kegiatan budidaya ikan, hormon Oodev dapat merangsang pematangan gonad karena hormon Oodev ini mengandung pregnant mare serum gonadotropin dan antidopamin yang sama-sama berperan dalam pematangan gonad. Sekalipun hormon ini begitu populer di bidang budidaya ikan, pengaruh hormon ini terhadap pertumbuhan tubuh dan pematangan gonad terhadap ikan giru (Amphiprion clarkii) belum banyak diketahui. Penelitian ini bertujuan untuk mengevaluasi pengaruh dan menentukan dosis pemberian hormon Oodev dalam pakan terhadap pertumbuhan panjang dan bobot serta pematangan gonad ikan giru. Ikan giru diberi perlakuan dengan tiga dosis hormon Oodev berbeda yaitu 0 mL/ kg, 0,5 mL/kg, dan 1 mL/kg dengan tiga pengulangan selama 30 hari pemeliharaan. Hasil menunjukkan dosis 1 mL/ kg meningkatkan pertumbuhan panjang tubuh pada jantan (0,9 cm) maupun betina (0,7 cm) dan pertumbuhan bobot pada jantan (1,32 gram) maupun betina (3,05 gram) lebih tinggi dengan kontrol. Sejalan dengan pertumbuhan panjang dan bobot, dosis 1 mL/kg meningkatkan nilai gonadosomatic index jantan dan betina yaitu 0,47% dan 0,58% lebih tinggi dengan kontrol. Dari hasil yang diperoleh dapat ditarik kesimpulan bahwa hormon Oodev dengan dosis 1 mL/kg dapat meningkatkan pertumbuhan dan nilai GSI A. clarkii.

Sex determination, growth performance and survival of Clarias gariepinus juveniles were examined as they responded to 17-methyl testosterone (MT) and absolute ethanol mixed in their feed. Varying levels of 50 mgKg-1 /MT, 100 mgKg-1 /MT and 0 mgKg-1 /MT were used. These inclusion levels further served as treatments TCG 50, TCG 100, TCG 0. A total of 270 Clarias gariepinus juveniles were stocked in six (6) concrete stagnant systems of 2metre by 2metre square. Treatments were duplicated and TCG 0 served as the control. Duration was for One hundred and twenty one (121) days. The mean initial weights were taken as 0.05±0.00 a g for treatment TCG 0, 0.06±0.01 a g for treatment TCG 50 and 0.05±0.00 a g for treatment TC 100. Highest mean weight gain of 2.40±0.21 b g observed in the study was seen in the Clarias gariepinus juvenile tank TCG 50. Performance index showed treatment TCG 50 performed highest with value 116.02±0.00 a. Survival rate was highest in treatment TCG 0 with 92.22±1.57 a %, higher in treatment TCG 100 with 83.33±7.86 a % and high in treatment TCG 50 with 81.11±1.57 a %. Condition factor K was greater than 1 throughout the study showing well-being of the fishes; highest in treatment TCG 50 at value 6.67. Water quality parameters were at normal ranges throughout the study.
