“…Furthermore, Egg diameter increased in each treatment from the beginning to the end of the study. The results of this study indicated that the high value of egg diameter were treatment C. Yulianto et al [25] concluded that Oodev hormone contains PMSG hormone, where the FSH content is greater and the LH is less. FSH functions for egg maturation and LH functions for egg production.…”

Poropuntius tawarensis is an endemic fish belonging to the Cyprinidae family found in Laut Tawar Lake, Central Aceh, Indonesia. P. tawarensis has a limited distribution and the fertilization only occurs in the rainy season. The purpose of this research was to observe the effect of Oodev hormone with different doses on the maturity of P. tawarensis. This study was used completely randomized design (CRD) consisting of 3 treatments and 3 replicates. Treatments used were the hormone doses of 0.25 mL/kg, 0.50 mL/kg and treatment without hormone (control). The parameters used in this study were gonadosomatic index (GSI), egg diameter, coefficients of variation (CV) of egg diameter, fecundity, and hepatosomatic index. The study revealed the highest value found in a dose of 0.50 mL/kg which the value of egg diameter was 0.8791±0.02 mm, coefficients of variation of egg was 6.46±0.49% and fecundity was 869±33.99 egg/kg. While the highest gonadosomatic index was found in a dose of 0.25 ml/kg (10.41±2.03%). Moreover, the induction of Oocyte developer (Oodev) hormone on the maturity of P. tawarensis did not significantly affect the hepatosomatic index (HSI), but Oodev hormone was efficient to accelerate the gonad maturity of fish.

“…The vitellogenesis process in fish is responsible for the rise in GSI values [14]. The vitellogenesis process will continue until the fish spawns, at which point the gonads will develop in weight and size in tandem with the growth of the gonads, reaching their maximum size when the fish spawns [15]. The gonado index is computed by comparing body length, which is linked to fish growth.…”

Silver rasbora (Rasbora argyrotaenia) is a high-value commodity. The problem in cultivation of silver rasbora is long goanadal maturation period. The gonadal maturation period can be accelerated by manipulation of feed using omega-3. Omega-3 can affect reproductive performance, egg development, and fish embryogenesis. The purpose of this study was to determine effect of addition of omega-3 in feed on gonadal maturity level and fecundity of silver rasbora. The observed parameters are gonadal maturity level, gonado somatic index, gonado index and fecundity. This research applied a completely randomized design (CRD) method which consist of four treatments, namely control (0 mg/kg feed), P1 (2500 mg/kg feed), P2 (5000 mg/kg feed), and P3 (7500 mg/kg feed). The result of this study was indicate addition of omega-3 to feed increased gonadal maturity at GML IV stage and had a signicantly effect on the gonado somatic index, gonado index, and fecundity of female silver rasbora. The optimal dose of omega-3 for silver rasbora gonads is 7500 mg/kg of feed, which results in an increase in gonadal maturity to GML IV with a GSI of 18,89 ± 2,24%, a GI of 143,63 ± 6,66 and fecundity of 924,76 ± 9,21 eggs/parent.

“…Kandungan pada Oodev memiliki hasil yang baik terhadap kematangan telur. Sejalan dengan pendapat Yulianto et al (2019) menyatakan bahwa FSH berfungsi pada proses ovulasi dan pematangan oosit sehingga ukuran diameter telur dapat bertambah dan pematangan oosit terbentuk sempurna karena pengaruh fungsi hormon gonadotropin yang diberikan. Rangsangan hormonal yang sesuai dapat meningkatkan diameter oosit yang dihasilkan oleh penyerapan lumen ovari.…”

Snakehead fish is a fish that has a high level of consumption and has many benefits in the health sector, but cultivation activities have not been carried out intensively because of the availability of snakehead fish which still utilizes catches from nature. In cultivation activities, the use of hormones is commonly used, one of which is used to support reproductive performance. One of them is the Oodev hormone, so this study aimed to determine the effect of Oodev with different doses on the final gonad maturation of snakehead fish. The research method used was a completely randomized design experiment with four treatments and three replications. The treatments were P0 (Oodev 0 mL/kg), P1 (Oodev 0.5 mL/kg), P2 (Oodev 1 mL/kg), P3 (Oodev 1.5 mL/kg). Oodev injections were carried out on TKG II fish at an interval of every 7 days. During maintenance, the fish were fed golden snails and small fish 2 times a day. The result of the research showed that Oodev is significant in the gonad maturation of common snakehead. The treatment P3 injection dose of 1.5 mL/kg with maturation gonad time for 16 days, ovi somatic index 4.26%, egg diameter increases of 0.113 mm, fertilization rate 91.43%, hatching rate 90.96. It was concluded that the Oodev injection had a significant effect on the gonad maturity of snakehead fish (P<0.05) in the P3 treatment (Oodev 1.5 mL/kg).Keywords: Channa striata; Dose; Gonad maturation; Hormone; Oodev
