Ikan lele sangkuriang (Clarias gariepinus var. sangkuriang) Merupakan salah satu ikan air tawar yang banyak dikonsumsi dan dibudidayakan di Indonesia (Pratiwi, 2014). Untuk meningkatkan produksi ikan lele dapat dilakukan dengan cara menerapkan teknik Pemijahan buatan. Pemijahan buatan bisa dilakukan dengan perangsangan menggunakan hormon berupa Ovaprim. Ovaprim memiliki kandungan GnRH dan antidopamine. Namun, Hormon ovaprim ini memiliki harga yang mahal yaitu berkisar antara Rp 28.000- 30.000/ml, sehingga perlu dipelajari alternatif bahan dengan menggunakan hipofisa ayam broiler. Rancangan pen

The present study compared the effectiveness of the Carp pituitary gland extract (PGE) and the synthetic hormone Ovaprim on spawning success of the stinging catfish, Heteropneustes fossilis during induced breeding. The PGE hormone was administered at 6 mg/kg of body weight for females and 2 mg/kg of body weight for males. In contrast, Ovaprim was administered at 0.3 ml/kg body weight and 0.1 ml/kg of body weight for females and males, respectively.

Fifteen broodfish, (9 males and 6 females) having mean weight of 1kg were procured and used for the study. All brood fish were selected by external morphological characteristics following standard procedures. The hatchlings were further raised for ten weeks for growth study. The water parameters monitored were dissolved oxygen (6.65mg/l), pH (7.3) and temperature (28ºC). The results showed that there were no significant differences (p>0.05) in the mean fecundity

The research work was conducted for induced breeding of Vietnames Koi (Anabas testudineus) using carpPG extract and Ovaprim hormone at Tasty Fish and Feeds Industries Limited, Melandah, Jamalpur during March to May, 2015. Brood fishes were reared for 4-5 months in the brood rearing pond by providing farm-made artificial feed (containing 32% protein) for maturation before onset of breeding season. Two different hormones i.e., PG-PG (both for male and female), and PG-Ovaprim (PG for male and Ovaprim for female) were used as inducing agents for the purpose of induction of breeding A. testudineus.

The effects of reduced doses of Ovaprim™ (GnRHa + domperidone) on sperm release of Brycon orbignyanus and Prochilodus lineatus were evaluated. Furthermore, sperm quality was compared among fresh, equilibrated and post-thaw samples. Males received a single and reduced dose of Ovaprim™ (0.125 or 0.25 ml/kg); control males received pituitary extract (cPE; 3 mg/kg). Fresh sperm was evaluated for volume, concentration, seminal plasma osmolality and seminal plasma pH. Then sperm was diluted in a freezing medium, equilibrated for 15-20 min and frozen in nitrogen vapor vessel (dry-shipper). Sperm moti

Freshwater lobsters have been developed as a commodity for consumption since 2003. The need for this commodity is increasing but production is still very low, so the price of freshwater lobsters is quite high and expensive. Therefore, it is necessary to carry out reproduction to carry out the seeding process for Freshwater Lobsters (LAT) using an injection technique in the form of the Ovaprim Hormone to accelerate the maturity of the LAT gonads. This study aims to examine the administration of different doses of the ovaprim hormone on the maturation of freshwater lobster broodstock. The resear

The results of spawning in sangkuriang catfish farming do not always go according to the expected results, as many eggs died before hatcing. Therefore, it is necessary to use spawning hormones which can improve egg quality in order to increase profits in cultivation. This research was aimed to determine the difference on success performance of sangkuriang catfish using HCG, Ovaprim, and Spawnprim. This research used a randomized block design (RAK) with 3 treatments i.e P1 (HCG 500 IU/kg), P2 (Ovaprim 0,5 ml/kg), P3 (Spawnprim 0,5 ml/kg) and 3 groups of repetition i.e K1 (spawning group day-1),

The kissing gourami (Helostoma temminckii) is a freshwater species increasingly cultivated in controlled aquaculture systems. However, its production is hindered by the limited availability of broodstock and fry, which still heavily depend on natural catches that fluctuate seasonally. To address this challenge, controlled environment aquaculture offers a sustainable solution to boost the kissing gourami population. One effective method is semi-natural spawning through gonadotropin hormone induction using Ovaprim®, which promotes year-round reproductive readiness in broodstock. This study aims
