“…Oodev™ (oocyte developer) contains pregnant mare serum gonadotropin + dopamine antagonist (PMSG+DA) that can induce an increase in the GnRH level, which in turn stimulates the pituitary to generate gonadotropin; then, gonadotropin will stimulate the ovaries to mature the eggs in the fish (Nainggolan et al, 2014). Oodev™ successfully facilitates gonadal maturation in catfish (Pangasius hypophthalmus) (Agustinus, 2013), snakehead (Channa striata) (Anwar et al, 2018), Asian redtail catfish (Hemibagrus nemurus) (Putri et al, 2019), and Poropuntius tawarensis (Mellisa et al, 2022). Meanwhile, the use of Oodev™ in inducing barred loach gonadal maturation has never been reported.…”

Barred loach Nemacheilus fasciatus are unable to reproduce naturally in captivity due to the lack of environmental cues and gonadal maturation occurs slower than in the wild. To optimize breeding procedures for this fish species, we determined whether hormone application via the gills was an effective process and assessed hormone dosage treatments. Oodev™ was used to induce gonadal maturation and Ovaprim™ was used to induce spawning via a topical gill approach. Multiple maturation parameters such as gonadal-somatic index (GSI) and hepatosomatic index (HSI), fecundity, and egg diameter; and spawning parameters such as latency period, egg produce, fertilization rate (FR), hatching rate (HR), survival rate (SR) were recorded and compared between the hormone dosage treatments and control treatment. Both the Oodev™ gonadal maturation induction and Ovaprim™ spawning induction were effectively applied to barred loach via topical gill application. Gonadal maturation parameters were positively correlated with dosage and all were significantly different. Fry survival rate was not different between doses. The optimal dose of Oodev™ (0.75 µL/g fish) resulted in male GSI of 5.334 ± 0.320%, female GSI of 15.501 ± 0.675%, male HSI of 0.416 ± 0.023%, female HSI of 1.670 ± 0.104%, egg fecundity 4584.20 ± 493.216 eggs, egg diameter 0.964 ± 0.0151 mm. Ovaprim™ optimal dosage (3.00 µL/g female and 1.50 µL/g male) was resulted latency period 11.05 ± 0.52 hours, egg produced 3504.83 ± 358.57, FR 96.77 ± 0.88%, HR 83.62 ± 3.78%, and SR 91.44 ± 2.53%.

The Osteochilus melanopleurus (Bleeker, 1852) is one of the endogenous fish in the Siak River waters of Riau province which has high economic value. However, the fulfillment of needs still depends on the catch in nature. Efforts to overcome these problems are the availability of mature gonads. Broadly to accelerate the maturation of gonads through hormone induction until the fish are ready to be spawned to produce fish fry continuously. The purpose of this study was to analyze the effect of gonadotropin and anti-dopamine hormone induction with the trademark “Oodev” on the final gonad maturity (TKG) of the prospective broodstock of O. melanopleurus. The research was conducted from April to August 2021 in the fish rearing column and the experimental pond, Faculty of Fisheries and Marine Science. The research method was a Completely Randomized Design with 4 treatment levels and 3 replications, while the treatments were P0 (without Oodev injection), P1 (Oodev dose 0.5 mL/kg), P2 (0.7 mL/kg), and P3 (0,9 mL/kg). Measured responses: percentage of broodstock that reached TKG and egg diameter. The results of the research that have been carried out, the measurement of the diameter of the eggs produced showed that the use of the Oodev hormone at a dose of 0.7 mL/kg body weight of O.melanopleurus given every week for twelve weeks was able to stimulate the development of the gonads of O.melanopleurus. Ovaprim injection of 0.7 mL/kg body weight produced 89,566 eggs with a latency of 4 hours. oodev injection dose of 0.7 ml/kg BW or P2 treatment has succeeded in achieving a TKG of 82%.
