“…The highest percentage of mature male broodstock was shown in the group B. The factor affecting gonad maturity and hormones was the shrimp's age (Mukti et al, 2020). The male broodstocks of tiger shrimp used in this study were more than 10 months old.…”

The purpose of this study was to evaluate the influence of different 17αmethyltestosterone injection frequencies at optimal doses to improve the quality of spermatophore and reproductive performance of captive male broodstock of tiger shrimp Penaeus monodon. Broodstocks of tiger shrimp weighing 51-65 g for males and 86-161 g for females were collected from ponds and stored in a 3,000 m 3 concrete tank. Male broodstocks were injected with 17α-methyltestosterone at the optimized protocol at 300 ng/100 g body weight at different injection frequencies, three times, four times, and five times at seven-day intervals. As a control, male broodstocks were injected with a saline solution to determine the spermatophore quality. Evaluation of the reproductive performance of the captive male was observed in the captive female broodstock tiger shrimp using artificial insemination. The weight of spermatophore (0.041 g), gonadosomatic index (7.71%), the total number of spermatozoa (64 × 10 6 cells/mL) significantly increased, and the percentage of abnormal spermatozoa significantly decreased by 73% as well as hatching rate increased to 43.14% at the injection frequency of four times compared to the other treatments. In conclusion, injection of 17α-methyltestosterone at the dosage of 300 ng/100 g body weight at the frequency of giving four times was effective enough to improve the reproductive performance of captive tiger shrimp. Therefore, the method proposed can be a strategy to produce better larvae and increase the income of the aquaculture business.

“…GnRH promotes the secretion of LH by stimulating the pituitary gland. Then, LH promotes testosterone hormone synthesis by stimulating the testis's Leydig cells (Mukti et al, 2020). Naturally, the process of sperm maturation in fish is influenced by environmental signals that the hypothalamus will capture.…”

“…However, the percentage decrease in the normal spermatozoa count indicated by broodstocks given oral 17α-MT was 42% lower compared to 17α-MT injection. Some of the factors that affect sperm production in male tiger shrimp P. monodon are shrimp weight, age, and environmental conditions of cultivation [21,22]. In general, the size of shrimp that can be used as a broodstock is the size achieved at the time of the first maturity that occurs in nature [22].…”

The effects of 17α-methyltestosterone administration on spermatophore quality in captive broodstock of tiger shrimp Penaeus monodon were investigated using injection method and oral method based on the optimized protocol. The experiment was designed to compare the oral administration group and injection group with two replications during a 38-day experimental period. Captive male broodstock of tiger shrimp weighing 57-95 g was collected from ponds and stored in a 10,000 m3 concrete tank (20 shrimp/tank). Male broodstocks were injected and orally administrated with 17α-methyltestosterone at the dose of 300 ng/100 g body weight. Data indicates that the injection of 17α-methyltestosterone showed the percentage of mature broodstock count and the percentage of normal spermatozoa count 1.07 and 1.38% higher and significantly differs from oral administration through mixing in feed at the maturation stage. However, at the time of the maturation and 1st re-maturation of both the methods, the weight of the spermatophores and the number of spermatozoa did not show any difference. Based on the comparison of the two methods used, the results are obtained that the administration of the hormone 17α-methyltestosterone can be done both through mixing in feed and through injection, but the administration of hormones through injection gives better results than the broodstock matures first simultaneously.

“…The value of the gonadosomatic index (GSI) can vary because it is closely related to the weight of the gonads and the body depending on the individual. Mukti [21] revealed that GSI increases with the increasing gonadal maturity stage. It was showed in this study, the high GSI were found in treatment B and C with the stage III, IV and V. In this study, the GSI value obtained was less than 20%.…”

Induction of oocyte developer hormones (oodev) on the maturity of Poropuntius tawarensis

2022

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.
