Effect of Dietary Vitamin E on Growth, Fecundity, and Leukocyte Count in Goldfish (Carassius auratus)

Abstract

As from January 2010 The Israeli Journal of Aquaculture-Bamidgeh (IJA) will be published exclusively as an on-line Open Access (OA) quarterly accessible by all AquacultureHub (http://www.aquaculturehub.org) members and registered individuals and institutions. Please visit our website (http://siamb.org.il) for free registration form, further information and instructions. This transformation from a subscription printed version to an on-line OA journal, aims at supporting the concept that scientific peer-reviewed publications should be made available to all, including those with limited resources. The OA IJA does not enforce author or subscription fees and will endeavor to obtain alternative sources of income to support this policy for as long as possible.

Influence of antioxidants on the growth performance, gonadosomatic index and biochemical properties of gonad and fertilization success in koi carp (Cyprinus carpioL.)

“…The female fish, when fed with vitamin E supplemented feed at 400 mg/kg, exhibited highest GSI value. This was in accordance with the findings of James et al (2008), who reported higher GSI in goldfish when fed with 300 mg vitamin E/kg diet. Similar results were confirmed by Gupta et al (1987), who observed higher GSI in Labeo rohita , Catla catla and C. carpio , by incorporating vitamin E in fish diets.…”

“…In the present study, both male and female koi carp exhibited higher growth performance indices only when fed with feed containing 200 mg/kg of vitamin E. The present result was in accordance with James et al (2008); Muchlisin et al (2016), and Sembiring and Hutapea (2019) who inferred that vitamin E at 300 mg/kg feed had the best weight gain and specific growth rate in goldfish ( Carassius auratus ), Javan mahseer ( Tor tambra ) and sand fish ( Holothuria scabra ) respectively. The authors also suggested that vitamin E affected the gonadal development, leading to gain average body weight in fish species.…”

“…Similar results were found in Mali Fish ( Labeobarbus festivus ), where lower hatchability of eggs was caused by process of egg fertilization and reduced spawning rate (Aryani et al, 2018). In a study conducted by James et al (2008) reported that a low level of vitamin E probably reduced the gonad development and fecundity in gold fish. Fish fed with vitamin E at different concentrations performed better when compared to fish fed with vitamin C at different concentrations.…”

“…with James et al (2008); Muchlisin et al (2016), and Sembiring and Hutapea ( 2019) who inferred that vitamin E at 300 mg/kg feed had the best weight gain and specific growth rate in goldfish (Carassius auratus), Javan mahseer (Tor tambra) and sand fish (Holothuria scabra)…”

“…However, studies regarding the effect of vitamin E on reproductive performance in male fish are scarce, although, in humans and animals, it has been used for improving sperm quality and preventing male infertility. James et al (2008) studied the effects of different levels of dietary vitamin E (0, 100, 200, 300 and 600 mg/kg diet) on growth, gonad weight, fecundity and leukocyte count of goldfish (Carassius auratus) and found that fish fed with 300 mg vitamin E/kg diet had the best feeding rate, weight gain, specific growth rate, heavier gonads, the higher number of eggs with better hatchability, high egg weight, diameter and larvae weight and length, lymphocyte and monocyte populations. Aryani et al (2018) analysed the influence of dietary incorporation of vitamin E (150, 300, 450 mg/ kg feed) on the maturity of gonads, somatic ovi index, fecundity, egg diameter and hatching rate in Mali fish (L. barbusfestivus) and stated that fish fed with vitamin E at 300 mg/kg feed gave the best results.…”
