Evaluation of PMSG (Oodev®) application on hepatosomatic and gonadosomatic index of snakehead fish

Abstract

<p class="NoParagraphStyle"><strong>ABSTRACT</strong></p><p class="NoParagraphStyle"><strong> </strong></p><p class="NoParagraphStyle">Snakehead fish (<em>Channa striata</em>) is a freshwater fish commodities that have high economic value, while their needs depend on natural catching. In general, hormonal induction commonly used for the efficiency of female parent utilization and enhancement quality and quantity of fish fry. One of the hormones that can be used is pregnant mare serum gonadotropin (PMSG) and antidopamine with trademark Oodev®. These hormones contain many elements follicle stimulating hormone (FSH) which can trigger the early stages of gonad maturity. The purpose of this research was to determine the effectiveness of hormone PMSG on gonadosomatic index (GSI) and hepatosomatic index (HSI). The size of female fish was 30−40 cm, weighing of 500−700 g, adapted in the aquarium and then induced with different doses of PMSG, namely: treatment A dose: 0.75 mL/kg; B: 1.0 mL/kg; C: 1.25 mL/kg; D: 1.5 mL/kg and be repeated three times. Fishes were then reared up to 72 hours to determine the development of GSI and HSI. The results showed that the best treatment was at dose of 1.25 mL/kg with GSI and HSI values of 1.37% and 3.35%, respectively.</p><p class="NoParagraphStyle"> </p><p class="NoParagraphStyle">Keywords: PMSG, GSI, HSI, snakehead fish</p><p class="NoParagraphStyle"> </p><p class="NoParagraphStyle"> </p><p class="NoParagraphStyle"><strong>ABSTRAK</strong></p><p class="NoParagraphStyle"> </p><p class="NoParagraphStyle">Ikan gabus (<em>Channa striata</em>) merupakan salah satu komoditas air tawar yang mempunyai nilai ekonomi tinggi. Saat ini pemenuhan kebutuhan hanya bergantung pada hasil penangkapan dari alam. Pada umumnya cara pemijahan buatan dengan induksi hormon dilakukan untuk efisiensi penggunaan induk serta peningkatan kualitas dan kuantitas benih ikan. Salah satu hormon yang dapat digunakan adalah <em>pregnant mare serum gonadotropin</em> (PMSG) dan antidopamin dengan merk dagang Oodev®. Hormon-hormon tersebut banyak mengandung unsur <em>follicle stimulating hormon </em>(FSH) yang dapat memicu kematangan gonad tahap awal. Tujuan dari penelitian ini adalah untuk menguji efektivitas hormon PMSG terhadap nilai indeks gonadosomatik (IGS) dan indeks hepatosomatik (IHS). Induk ikan gabus yang digunakan berukuran 30−40 cm dengan bobot 500–700 g, diaklimatisasikan di akuarium kemudian diinduksi hormon PMSG dengan perlakuan dosis A: 0,75 mL/kg; B: 1,0 mL/kg; C: 1,25 mL/kg; D: 1,5 mL/kg dan dilakukan pengulangan sebanyak tiga kali. Selanjutnya ditunggu hingga 72 jam untuk mengevaluasi perkembangan IGS dan IHS nya. Hasil penelitian menunjukkan bahwa perlakuan terbaik adalah dosis 1,25 ml/kg dengan nilai rata-rata IHS 1,37% dan IGS 3,35%,</p><p class="NoParagraphStyle"> </p><p class="NoParagraphStyle">Kata kunci: PMSG, IGS, IHS, ikan gabus</p><p> </p>

Effect of Pregnant Mare Serum Gonadotropin and Antidopamine on the gonads of female bileh fish (Rasbora maninjau)

“…Growth in prospective broodstock fish increases due to gonad development [19]. The increase in gonad weight goes hand in hand with the IGS value, the greater the gonad weight, the greater the IGS value [13].…”

“…With the presence of antidopamine, the neurotransmitter is expected not to inhibit gonadal maturation so that the gonadal maturation process can be achieved more quickly. The combination of PMSG and antidopamine hormones has a positive effect on the reproductive performance of Tor douronensis, Channa striata, Poropuntius tawarensis, and Osteochilus hasselti [11,12,13,14,15]. The combination of PMSG and antidopamine hormones is expected to provide optimal results in the gonad maturation of bileh fish.…”

Hormonal induction maturation of silver pompano Trachinotus blochii

“…This result was influenced by some factors, i.e hormone contents, doze, and nutrient levels to support the gonad maturation process. PG600 is composed of PMSG (containing FSH+LH) (Hutagalung et al, 2015) and hCG (FSH+LH) (Nuraini et al, 2008), therefore PG600 was possibly better to induce the fish gonad maturation. Another treatment, such as control, still included in TKG I due to the existence of oogonium that was dominantly found on the egg cells histological figure, while hCG and PMSG treatment showed a gonad development as egg nucleus occurred and moved at the egg corner, but not yet reaching a phase when the egg cell merged as seen on PG600 treatment.…”

“…The PMSG hormone has many been applied in mammals to trigger superovulation and induce follicle production [11]. Furthermore, the PMSG application has also been performed in fish, as the 20 IU/kg dose could improve the female striped catfish broodstock reproduction performance apart from the spawning season [12], and the 1.25 g/kg PMSG dose could increase the GSI and HSI values of female snakehead fish broodstock at 3.35% and 1.37%, respectively [13]. The PMSG hormone induction at a 1.5 g/kg dose in snakehead fish could trigger the vitellogenesis process to provide a matured broodstock gonad faster [14].…”
