Dietary vitamin E on the reproductive performance of the fantail goldfish Carassius auratus auratus

Abstract

This research was conducted to examine the different dose of vitamin E in the diet on female broodstock reproduction performance of the fantail goldfish Carassius auratus auratus. This research consisted of four treatments with three replications. The use of vitamin E doses was 0, 125, 250, and 375 mg/kg. The vitamin E was dissolved in vegetable oil and mixed with albumen as a binder in feed. The vitamin E was sprayed at feed and was air dried. Female broodstock of the fantail goldfishes were reared for 40 days. The result showed that 375 mg/kg treatment performed the highest quality of reproduction. Egg diameter, gonadosomatic index, fecundity, and germinal vesicle breakdown of fish which are treated by 375 mg/kg vitamin E were respectively 0.92±0.05 mm, 8.86±4.62%, 56.00±29.18%, and 67.35±17.67% higher than control. Thus, 375 mg/kg of dietary vitamin E suplementating was a best dose to improve female broodstock productivity of the fantail goldfish Keywords: female broodstock, fantail goldfish, vitamin E, reproduction quality ABSTRAKPenelitian dilakukan untuk menguji suplementasi vitamin E dengan dosis berbeda dicampur ke dalam pakan komersial terhadap produktivitas induk betina ikan komet Carassius auratus auratus. Penelitian ini menggunakan empat perlakuan dengan tiga ulangan. Dosis vitamin E yang diberikan, yaitu 0, 125, 250, dan 375 mg/kg pakan. Vitamin E dilarutkan dalam minyak nabati dan dicampur dengan putih telur sebagai perekat pada pakan. Vitamin E disemprotkan ke pakan dan dikeringanginkan. Induk betina ikan komet pascasalin dengan bobot 72,78±19,47 g diberi perlakuan selama 40 hari. Hasil penelitian menunjukkan bahwa induk betina ikan komet yang diberi suplementasi vitamin E sebanyak 375 mg/kg dalam pakan memiliki diameter telur 0,92±0,05 mm, gonadosomatic index 8,86±4,62%, fekunditas 56,00±29,18 butir/g ikan, dan germinal vesicle breakdown 67,35±17,67% yang lebih tinggi dibandingkan kontrol. Dengan demikian, suplementasi vitamin E sebesar 375 mg/kg pada pakan adalah dosis terbaik dalam meningkatkan produktivitas induk betina ikan komet.Kata kunci: induk betina, ikan komet, vitamin E, kualitas reproduksi budidaya ikan hias pada skala massal. Hal ini akan memengaruhi kualitas dan kuantitas dari benih yang dihasilkan. Menurut Mansa dan Allah (2011), upaya untuk meningkatkan mutu dan jumlah produksi ikan hias dapat dilakukan melalui perbaikan nutrisi pada pakan induk. Perbaikan nutrisi pakan induk ikan akan berpengaruh positif tidak hanya pada kualitas telur dan sperma, tetapi juga terhadap mutu dan jumlah benih yang dihasilkan. Salah satu cara yang dapat dilakukan untuk perbaikan nutrisi pada pakan induk yaitu melalui suplementasi vitamin E.

Effect of vitamin E on the quality of egg bonylip barb fish Osteochilus vittatus (Valenciennes, 1842)

“…However, previous report showed the administration of vitamin E to fish feed in the amount of 300 mg kg -1 provides the best fecundity value compared to comet fish (James et al, 2008). Meanwhile, the administration of vitamin E at 375 mg kg -1 produced fecundity value of 56 eggs per gram compared to gold fish Carassius auratus (Arfah et al, 2013). In addition, the similar reports were also reported several researcher, for instance Izquierdo et al (2001), and Aryani and Hamdan (2014).…”

“…This resulted to average values ranged between 18.5-21.43% and 25.45-27.88%, respectively, where the vitamin E acts as an antioxidant in an effort to prevent the oxidation of fatty acids during vitelogenesis. Research reported by the vitamin E potentially prevents fat oxidation during vitelogenin (Arfah et al, 2013). The fatty acid content was continuously allocated to the egg during gonad development later used as energy reserves for subsequent application.…”

“…For this reason, the role is crucial in reproduction and egg quality improvement (Tahapari et al, 2019). Previous reports showed that the addition of vitamin E in feed was successfully improved the egg production and quality of Osteochilus kelabau (Nasution and Nuraini, 2014), Oreocromis niloticus (Nacimento et al, 2014), Carrassius auratus (Arfah et al, 2013); Osteochilus hasselti (Tarigan et al, 2017); and Oxyeleotris mamorata (Wahyudi et al, 2016).…”

GONAD DEVELOPMENT OF SANDFISH (Holothuria scabra) FED WITH VITAMIN E-SUPPLEMENTED DIET

“…Cultured sandfish broodstock needs longer time to mature and re-mature after spawning (Sembiring et al, 2017). Our proposed alternative to improve the reproduction performance of sandfish broodstock is by feeding them with vitamin E-supplemented feed which has shown to be effective for other freshwater fish and invertebrate species such as Mali fish (Labeobarbus festivus) need 150-450 mg/kg feed (Aryani et al, 2014), goldfish (Carassius auratus) need 375 mg/kg feed (Arfah et al, 2013), freshwater lobster, Astacus leptodactylus need 1,000 mg/kg feed (Barim-oz et al, 2011). Guppy fish, Poecilia reticulata need vitamin E 1,000 mg/kg feed for growth and good reproduction performance (Mehrad & Sudagar, 2010).…”

Optimizing the gonadal performance of broodstock Helostoma temminckii with addition of enrichment ingredients in feed

“…The addition of enriching ingredients in the form of glutathione and vitamin E is thought to be able to maintain the presence of fat granules, thereby increasing the number and size of egg yolk granules, resulting in an increase in egg volume and diameter [36]. As stated by [37], which stated that the addition of vitamin E to the feed can increase the size of the egg diameter of comet fish (Carassius auratus auratus). The egg must contain all the nutrients needed by the developing embryo and larva after the egg is fertilized so that the fish can meet their needs to initiate the consumption of external food.…”
